    COMPANY,
    Defendant and Appellant.
    APPEAL from a judgment of the Superior Court for Los Angeles County,
    Stuart M. Rice, Judge. Reversed and remanded.
    Southern California Edison Company, Patricia A. Cirucci, Brian A. Cardoza,
    Carla M. Blanc; Lim, Ruger & Kim, Christopher Kim, Sandra Sakamoto, Arnold
    Barba, Julie Kwun; Greines, Martin, Stein & Richland, Timothy T. Coates,

    Grassini, Wrinkle & Johnson and Roland Wrinkle for Plaintiff and
    Respondent.
    Defendant Southern California Edison Company (Edison) appeals from a
    judgment following a jury trial in which the jury found in favor of plaintiff Simona
    Wilson on her claims for intentional infliction of emotional distress (IIED),
    negligence, and nuisance, and awarded her $1,050,000 in compensatory damages
    and $3 million in punitive damages. All of her claims are based upon her
    allegation that Edison failed to properly supervise, secure, operate, maintain, or
    control the electrical substation next door to plaintiff’s house (the Topaz
    substation), allowing uncontrolled stray electrical currents to enter the home. Stray
    current (or stray voltage) is the unavoidable byproduct of grounding an electrical
    system.
    The gas company found stray voltage on Wilson’s gas meter the year after
    she moved into the house, and again two years later. Edison paid for certain
    measures taken by the gas company, which virtually eliminated the voltage on the
    meter. After Wilson remodeled her master bathroom (four years after she moved
    into the house), she began to feel low levels of electricity in her shower, because
    the shower had metal pipes and the drain was connected to the ground, which
    allowed the stray electricity to flow when someone touched the shower while in
    contact with the drain. Edison offered to replace all or a portion of the metal pipes
    with plastic, which would eliminate the voltage in her shower, but Wilson refused
    the offer and insisted that Edison eliminate all stray voltage on her property. She
    subsequently filed the instant lawsuit.
    Edison contends that Wilson’s claims fall under the exclusive jurisdiction of
    the California Public Utilities Commission (the commission or PUC), that no
    substantial evidence supports her claims, that the damages award is excessive, and
    that punitive damages were unjustified. We conclude that the PUC has not
    exercised its authority to adopt a policy regarding the issues in this lawsuit, and
    therefore it does not have exclusive jurisdiction over Wilson’s claims. But we also
    2
    conclude that Wilson failed to present sufficient evidence to support her IIED and
    negligence claims, or to support an award of punitive damages. Finally, we
    conclude the verdict on the nuisance claim cannot stand because the trial court
    refused to give Edison’s proffered instruction regarding causation of Wilson’s
    physical symptoms, and therefore the jury relied upon irrelevant evidence when
    determining that claim. Accordingly, we reverse the judgment, order judgment
    entered in favor of Edison on the IIED and negligence claims, and remand to the
    trial court for a retrial on the nuisance claim.
    BACKGROUND
    A.    Fundamentals of Electrical Distribution Systems and Electricity
    Analysis of the facts and issues in this case requires a basic understanding of
    electricity and electrical distribution systems.
    Electricity is produced at a generating plant. Because it is not economical to
    send electricity over long distances at low voltages, the electricity produced at the
    plant is stepped up through transformers to a very high voltage before it is sent out
    over transmission lines. A substation, such as Edison’s Topaz substation at issue
    in this case, receives the high voltage electricity from the generating plant and
    steps it down through transformers to 4,000 volts. It then sends the electricity over
    distribution lines out to the neighborhood power poles, where an additional
    transformer steps down the voltage to 240/120 volts before delivering the
    electricity to homes or businesses.
    In order for electricity to flow, there must be a complete circuit. In other
    words, when electricity is sent out from a transformer to a “load” (i.e., something
    that is using electricity, such as a light or appliance), it must have a return path.
    Typically, electricity is sent over one conductor (wire), called the “hot,” and
    returns on another conductor called the neutral. The flow of electricity is referred
    3
    to as “current” and is measured in amperes (or amps); voltage is the pressure that
    drives the current. The amount of current depends in part upon the amount of
    resistance in the circuit; e.g., a 100-watt lightbulb has less resistance than a 60-watt
    lightbulb, so there will be a larger current flowing through it (and therefore the
    bulb burns brighter).1
    For safety reasons, electrical systems usually are grounded. That means that
    at various points in the system, including at the substation, a connection is made
    from the neutral to the ground, i.e., the earth. Because the earth is conductive, it
    can provide a return path for the flow of electricity. Therefore, if, for example, an
    energized wire fell to the ground from the distribution lines, the earth would
    provide a path for the current to return to the substation, where a protective device
    would break the circuit. But the conductivity of the earth also can present a danger
    to someone who touches a source of electricity. If that person is in physical
    contact with the earth, electricity will flow from the electrical source, through his
    or her body, to the earth and on to the distribution system or substation, thus
    completing the circuit. The amount of current will depend on the resistance of the
    person’s body, the amount of contact area, and the amount of voltage present.
    In a grounded electrical system, there will always be some current flowing
    back to the substation through the earth. This is referred to as neutral-to-earth
    voltage, or NEV, and it cannot be entirely eliminated. NEV is one cause of “stray
    voltage,” which is voltage of 10 volts or less appearing on objects, that are not part
    of an electrical system, that can be simultaneously contacted by members of the
    1
    The amount of current also depends on the amount of voltage. The amount of
    current is calculated using Ohm’s Law: current (in amps) equals voltage (volts) divided
    by resistance (ohms).
    4
    general public.2 Metal objects, such as water pipes or gas lines, that are buried in
    or connected to the earth will conduct electricity, so if a person in a home touched
    a water pipe that was energized due to NEV while also touching the earth or
    another conductor at a different voltage, a circuit would be completed and current
    would run through that person’s body. This “touch potential” can be eliminated by
    replacing metal pipes with plastic pipes or installing isolators (such as a short
    section of plastic pipe) to stop the flow of electricity onto metal fixtures, or by
    connecting (or “bonding”) the two conductors to equalize the voltage between the
    two.
    The physiological effects of current flowing through a person’s body
    depends upon the amount of the current. According to a leading reference, a
    woman who encounters a current of 0.3 milliamps (mA) would not feel anything.
    At 0.7mA, she would feel a slight tingling; that typically is the perception
    threshold. At 1.2mA, she would feel a shock, but it would not be painful and
    muscular control would not be lost. She would feel a painful shock at 6mA, but
    she would still have muscular control. The let-go threshold is at 10.5mA, and at
    15mA, she would feel a severe shock, have muscular contractions, and her
    breathing could be difficult.3 Administration of currents on patients often is used
    2
    Stray voltage also can be caused by wiring faults (i.e., a short circuit in which an
    energized conductor makes contact with a grounded surface) or corrosion of a neutral
    conductor.
    3
    These current figures are for 60-Hz, alternating current, like the electricity
    supplied to homes. Another leading reference chart, which takes into account the amount
    of time of the contact, shows that perception is possible up to 0.5mA, and that current
    above 10mA likely would produce involuntary muscle contractions, but there usually
    would not be any harmful physiological effects.
    5
    by physicians to determine whether they have nerve damage; they typically
    administer currents of 20 to 50mA, and can administer up to 120mA.4
    B.      History of the Property
    The house at issue in this case is located at 904 Knob Hill Drive in Redondo
    Beach, next door to Edison’s Topaz substation. Edison owned the house until
    1999.
    1.    1995-1997
    In 1995, Edison rented the house to the Pantucci family. Before renting the
    house to the Pantuccis, a corporate real estate agent from Edison asked Edison’s
    facilities manager to take a look at the electrical system because a previous tenant
    had complained that she got a shock in the kitchen from the sink or refrigerator.
    Edison hired an electrical contractor, Precision Electric, to go through the
    electrical panels and the house to make sure everything was in order. Precision
    Electric took voltage readings by the sink to the ground, and found no voltage.
    The contractor replaced a ground clamp and went through the entire house, but did
    not find any electrical problems. The contractor was called back to the house after
    another Edison agent touched the dishwasher door while standing in water (the
    dishwasher had leaked) and felt a shock. When Precision Electric checked the
    dishwasher, the water was gone, and there was no voltage between the dishwasher
    and a tack strip on the floor. The contractor told Edison the shock could have been
    4
    It is not clear if these applications involve alternating current or direct current. For
    direct current, the perception threshold is from 3.5mA to 5.2mA; a person would feel a
    shock (not painful) at 6mA to 9mA, and a painful shock at 41mA to 62mA; the let go
    threshold is at 51mA to 76mA; and the person would feel a painful and severe shock,
    with muscular contractions and difficulty breathing at 60mA to 90mA.
    6
    caused by the power feed to the dishwasher being in water when the dishwasher
    leaked.
    Soon after the Pantuccis moved into the house, they began to experience
    shocks in the bathtub, at the washing machine, in a kiddie pool in the backyard,
    and at other places around the house. The shocks were mild, and no one was hurt.
    The Pantuccis complained to Edison a couple of times, and Edison sent people
    several times to try to fix the problem, but it never got fixed.
    In April 1997, Edison’s lease administrator, Tina Drebushenko (now Van
    Breukelen) emailed several Edison employees regarding some calls she recently
    received from Ms. Pantucci about shocks she received when touching faucets. Ms.
    Pantucci also told her that the family no longer used the bathtub. Drebushenko
    reported that “[t]his problem was supposed to have been corrected some time ago,
    but the tenants report that it never really was . . . they just put up with it and
    stopped calling.” She said that Ms. Pantucci told her that the shocks were getting
    stronger, so Precision Electric was sent to the house. The electrician who went
    there detected some stray voltage, and also believed there was faulty wiring
    somewhere in the electrical system. Precision Electric asked for an Edison
    troubleshooting team to meet it at the house the following week “to rule out any
    substation problems.” When Ms. Pantucci called the next day to report that the
    problem had gotten worse after Precision Electric left, Drebushenko contacted
    Precision Electric and the troubleshooting team to have them meet at the house that
    same day.
    In her email to her colleagues, Drebushenko emphasized that Edison needed
    to “get this matter resolved once and for all or determine if it can[‘]t be solved.”
    She stated that she had submitted the property to be released for sale, but that
    Edison might want it as a buffer. She said that if Edison could sell the property, it
    7
    would first have to fix the problem, but if the problem cannot be fixed, Edison
    should consider demolishing the structure.
    The Pantuccis moved out a few months later, in September or October of
    1997.
    2.    1998
    In January 1998, Mark Raidy was preparing the house for possible sale. He
    met with several Edison employees at the house to try to determine the source of
    the shocks and find a solution to fix the problem. They opened the main circuit
    breaker (i.e., shut off power to the house) and took readings. They found two amps
    flowing in the service drop (i.e., wire) from the backyard pole to the house. They
    took readings on the water pipe into the house and out to the sprinklers in the
    backyard, and found no current. They agreed that the other likely path for the
    current was the sewer pipe, and determined they should replace the sewer pipe
    with plastic. Once the sewer pipe was replaced, they would meet again, and have a
    troubleman there to perform a test.
    They also found stray voltage inside the house. They took a reading, and
    found over five volts from the damp carpet/tack strip between the kitchen and
    dining area and the ground on a kitchen outlet. They agreed to do more
    troubleshooting at their next meeting. In an email to the meeting participants,
    Raidy told them: “If we can solve these problems and feel comfortable that they
    won’t recur, we will proceed to market the home. If constant maintenance is
    needed to prevent the re-occurrence of the problem, we should probably retain the
    property so we can control the maintenance. If we can’t solve the problem, we
    should not allow the property to be inhabited.”
    8
    Sometime later, Edison found there was a problem on a distribution pole up
    the street from the house. When the problem was fixed, the stray voltage at the
    house stopped.
    In June 1998, Raidy made a site visit at the house with Edison’s sales and
    leasing manager, Charles Kraushaar. Raidy told Kraushaar about the reports by
    prior tenants of shocks at the property. He said that Edison had determined that the
    source of the shocks was a faulty transformer on a distribution pole up the street;
    the transformer was replaced, which eliminated the problem. Kraushaar touched
    the faucet and showerheads that previously had produced shocks to verify there
    were no more shocks. Kraushaar had no concern about stray voltage at the site,
    and authorized the release of the property for sale.
    3.     1999-2008
    Edison sold the house to the Ozerans in 1999. Edison did not receive any
    reports of shocks at the house for the next five years. In 2004, the Ozerans
    complained to Edison that the tenants of the house were getting shocked in the
    laundry room in the garage, in the yard at the hose bibs, and in one of the
    bathrooms. Edison employee Matthew Norwalk was asked to investigate as part of
    a team that included people from Edison’s substation, field engineering, and power
    quality departments. Norwalk performed voltage measurements, and found
    voltages ranging from 11 to 15 volts inside and outside the house.5 The team
    investigated the design and integrity of all connections on the distribution system,
    wiring within the home, and connections and design of the substation, and
    performed modeling of substation grounding.
    5
    Those measurements were taken without a resistor in the line, which was standard
    practice at the time. In 2009-2010, the industry determined that a standard burden
    resistor should be used to ensure consistency.
    9
    Thousands of man-hours were spent by members of the team and others,
    trying to determine the source of the problem. They de-energized and inspected
    each circuit at Topaz to see if there were issues with any of the circuits.
    Ultimately, they found and replaced some corroded connectors, and determined
    after a ground study that the grounding of the system could be improved. They
    concluded, based on modeling, that the voltage around the substation could be
    equalized to bring down the difference in voltage between the house’s ground and
    the waterlines on the property by adding a common neutral.6
    The common neutral plan was implemented in February 2005. Afterwards,
    the Edison team performed voltage measurements at the house, and found the
    voltage had dropped to approximately 3.5 volts (without a resistor). Using a 1,000
    ohm resistor to replicate the internal resistance of a human body, the Edison team
    determined that a voltage of 3.5 volts would not produce any harmful level of
    current (the level of current would be approximately 3.5mA). Norwalk spoke with
    the tenants of the house, and they were satisfied with the results. Edison received
    no more complaints of shocks or stray voltage until 2008.7
    6
    In a common neutral system, a jumper is placed between the primary neutral (the
    neutral wire coming from the substation on the distribution poles) and the secondary
    neutral (the neutral wire used to supply the individual homes from the transformer on the
    distribution pole). By connecting these neutrals, Edison utilizes the grounding systems of
    all surrounding homes as well as the grounds installed for the transformer itself.
    7
    The Ozerans sold the house sometime after July 2005 to the Boekers. In
    preparation for the sale, Dr. Ozeran asked Edison for a letter to give to the buyer
    confirming that the voltage levels were safe. Edison wrote that letter, and confirmed that
    the level of current was 3.5mA, which is below the safety threshold of 5mA used by
    Underwriter’s Laboratory, and would not pose a safety hazard.
    10
    C.     Events Leading Up To Present Lawsuit
    Wilson bought the property in March 2007 and moved in with her husband,
    Ryan Fisher, and son.8 She asked the previous owner whether there were any
    safety hazards in the home with respect to the substation next door, and was told
    there had been no problems. Neither she nor Fisher was aware of any voltage
    problem with the house until August 2008.
    1.     Voltage on the Gas Meter
    When Fisher came home from work on August 22, 2008, he found tags from
    the gas company saying that it had found a dangerous condition; there was
    electricity (measured at 7 volts) detected at the gas meter.9 The tags indicated that
    the gas had been turned off, and Fisher was advised to call the electric company.
    In response to Fisher’s call, Norwalk came to the house and took a voltage
    measurement on the gas pipe entering the property. He measured 1.8 volts without
    a resistor. Norwalk told the gas company that the source of the voltage appeared to
    be NEV, and that Edison would investigate to see if it could be further reduced.
    Edison tested the effect of removing the common neutral, and discovered that the
    voltage on the meter went down when they disconnected it but the voltage from the
    hose bib to the ground went up to 8 volts, so they restored the common neutral.
    Generally, when the source of voltage at a gas meter is NEV, the gas company will
    accept that voltage level. To verify that the source of the voltage was NEV, Edison
    8
    She was pregnant with her second son when she moved in; he was born a few
    months later. Her husband moved out of the house in March 2009, and she and her
    husband divorced in April 2010.
    9
    Employees of Southern California Gas Company are directed to shut off the gas
    and notify a supervisor if they find any electricity at a gas meter; a higher skilled person
    then goes to the location and measures the current.
    11
    placed a device on the gas meter to record the voltage to see if the voltage trended
    the load on the substation. Upon learning that Edison was monitoring the voltage,
    the gas company restored service to the house. Edison ultimately determined that
    the voltage changed in direct relationship to the loading of the substation, which
    confirmed that the source of the voltage was NEV.
    The gas company notified Wilson again in April 2010 that it had detected
    electricity on the gas meter, although it did not turn off the gas at that time. The
    gas company also found voltage on the gas lines of other homes and facilities in
    the area. Representatives from the gas company had several meetings with
    representatives from Edison to try to find a way to address the problem.
    Ultimately, it was determined that the best way to eliminate voltages on the gas
    lines and meters was to install isolators on the gas service lines to the customers’
    homes. Edison paid several thousand dollars for the installation of isolators, which
    was completed in 2012 and reduced the voltage on the gas meters to less than one
    volt.10
    2.    Voltage in the Shower
    In the meantime, in March 2011, Wilson remodeled her master bathroom.
    The construction was done to code by Wilson’s father, who was a contractor. As
    part of the remodel, Wilson replaced an elevated bathtub with a shower that had a
    metal drain in the concrete on the floor, so it had contact with the earth.11 After the
    remodel, Wilson began feeling a “tingling sensation” while she was showering, but
    10
    The gas company subsequently replaced the main gas pipeline with a plastic gas
    main.
    11
    When the house was inspected after Wilson filed her lawsuit, all of the plumbing
    in the house used plastic plumbing except for the master bathroom shower and an outside
    shower that was installed at the time of the remodel.
    12
    she thought it was a pinched nerve. On the evening of April 19, Wilson told her
    boyfriend, Jason Stelle, that she was “feeling some kind of tingling” while
    showering. Stelle got in the shower to adjust the showerhead and “started feeling a
    tingling sensation as well.” After touching the showerhead a few more times, he
    realized that the sensation was not from his body, but was from the fixture. He
    touched it numerous times that evening and the next day to confirm there was a
    sensation before calling an electrician.
    Wilson’s father and the electrician came to the house on April 20 and took
    voltage readings. They found voltage on the pipe leading to the showerhead. They
    started looking for the cause, eventually turning off all the power to the house, and
    found there still was voltage. The electrician and Stelle called Edison.
    An Edison field technician came to the house a few days later and took
    voltage readings in the shower and other areas of the house. The technician told
    Stelle that there had been a history of problems with the house, and that there was
    not much he could do other than check to make sure it was not something that
    could be immediately fixed. He did not explain what the problems were. Another
    Edison representative came by later that day and did a similar walk-through and
    took voltage readings.
    About a week later, Norwalk came to the house and met with Stelle. At
    Stelle’s request, Norwalk took voltage measurements at the master shower and at
    the gas meter. The voltage at the shower was 2.2 volts with a 500 ohm resistor and
    2.4 volts without the resistor; the readings at the gas meter were 0.5 volts with the
    resistor and 1.7 without. Norwalk tried to explain the cause of the voltage; as
    Stelle understood Norwalk’s explanation, the substation was causing a voltage
    potential across the property that was within Edison’s standards, and Edison did
    not have plans to do anything about it. Stelle asked Norwalk to come back to the
    house on May 6 to meet with Wilson and explain it to her.
    13
    On May 6, Norwalk and two other Edison representatives (including Bill
    Stone, a claims representative) met at the house with Wilson, Stelle, Wilson’s
    father, and her electrician. Norwalk measured the voltage on the shower, and
    showed the group that it measured 2.4 volts without the resistor and 2.2 volts with
    the resistor. They then went to the gas meter, where Wilson’s electrician said he
    had measured 11 volts.12 The electrician had not used a resistor when taking that
    measurement. Using the electrician’s meter, with the probes exactly where he
    placed them, Norwalk added a resistor to see what the true value was. The voltage
    was reduced to nearly zero. Norwalk next took voltage readings in the hallway
    bathroom that was used by the children. He measured from the drain grate in the
    bathtub to the shower controls. Although he found some voltage without the
    resistor, the voltage bled to zero when the resistor was added.13
    The group returned to the kitchen, where Norwalk showed Wilson the data
    from the voltage monitor that had been placed on her gas meter. He showed her
    that the voltage was lower in the morning and higher at night, in direct relationship
    to the substation, and explained the same is probably true in her shower. He
    estimated that the voltage in the shower in the evening would be around 3 volts.
    He noted there was missing data from December 2010 to April 2011, because the
    data card on the monitor had filled up, but explained that the voltages recorded
    12
    The electrician showed Norwalk that he measured the voltage by inserting one
    probe in the dirt next to the substation, outside the home’s property line, and touched the
    other probe to the gas line entering the home. According to Norwalk, this is not the
    correct way to measure the voltage because there is no touch potential between those two
    points, i.e., a person cannot be standing on the dirt next to the substation while touching
    the gas line at the house.
    13
    Norwalk explained that the reason there was less voltage in the bathtub was
    because there is a rubber gasket between the drain and the sewer line, so there is no
    electrical connection.
    14
    before the monitor stopped recording were almost exactly the same as those
    recorded after the data card was replaced.
    What happened next is in dispute.
    According to Wilson, Norwalk advised her to shower during off-peak hours
    when the stray voltage was lower and to modify her house to make it less
    conductive. He did not make any specific recommendations as to how to modify
    the house, nor did he offer to have Edison do any work on her house during that
    meeting.14 During her discussions with the group, Wilson told the Edison
    representatives that she wanted the stray voltage completely eliminated. When she
    tried to explain some symptoms she was having in her hands, Stone, the claims
    representative, turned toward her and yelled, “It’s just your nerves.” The meeting
    ended when Wilson asked for a copy of the simulation study on the stray voltage
    that Norwalk had told Stelle about during his prior meeting and copies of work
    orders showing what work had been done on the property before she bought it;
    Stone told her she needed to request those documents in writing.
    According to Norwalk, he explained to Wilson at the meeting that the
    voltage in the shower could be mitigated through bonding, or by replacing a
    portion of the copper plumbing in the shower with a short piece of plastic piping.
    He told her that she could have her contractor perform the work, if that made her
    more comfortable, and she could submit the bill to Edison.15 Wilson told him that
    14
    According to Wilson, Edison did not offer to install isolators or replace the pipes
    in the shower until after she had hired an attorney and moved out of the home. Wilson
    believed that replacing the pipes with plastic pipes “would be substandard” and “just a
    bandaid.” In any event, she testified that she would not have accepted the offer at any
    time, because “[t]he only thing that would be acceptable to me is to completely eliminate
    the stray voltage on my property.”
    15
    A claims investigations manager for Edison testified that he spoke by phone with
    Wilson a few days after the May 6 meeting and told her he understood that Edison’s field
    personnel had determined the best way to address the voltage issue was to put a plastic
    15
    she did not want to expose her family to any more dust from construction. She
    became upset that Edison could not remove the voltage by doing something within
    the substation, and the meeting ended.
    Wilson moved out of the house in September 2011, after an inspector she
    hired told her she should get out. The inspector was a building biologist whose
    expertise was in electromagnetic fields. She sold the home in January 2013.
    3.     Wilson’s Symptoms
    After Wilson started feeling the electricity in the shower, she started
    throwing up all the time, and her body felt extremely weak. She started to have
    muscle fatigue and muscle spasms, and her hands were shaky. She could not hold
    a cup of coffee or type, and had constant numbness, pain, and tingling in her hands
    and feet.16 She had episodes in which her hands and feet turned red and were
    warm to the touch.
    She went to a neurologist, Dr. Rederich, in May 2011. Dr. Rederich
    performed some simple tests on her, and diagnosed her with nerve damage. He
    prescribed pain medication, and told her the nerves would regenerate over time.
    When her symptoms got worse, Wilson returned to Dr. Rederich. He told her that
    he thought she might be developing secondary erythromelalgia, a rare condition for
    which there was no cure, and referred her to a specialist, Dr. Beydoun. Dr.
    Beydoun concluded she did not have secondary erythromelalgia or nerve damage,
    insert into the metal plumbing. He told her that Edison would pay for the work, and put
    her up for a day or two while it was being done, but Wilson rejected the offer and said
    she wanted Edison to buy her house.
    16
    Wilson testified that many of these symptoms stopped after she had a
    hysterectomy in January 2012.
    16
    but he could not rule out the possibility that she had primary erythromelalgia,
    which is an inherited condition.
    D.     The Present Lawsuit
    On September 11, 2011, Wilson, on her own behalf and as guardian ad litem
    for her children, filed a complaint for damages against Edison, the Boekers (who
    sold the house to her), and the Boekers’ real estate agents. We need not discuss in
    detail the proceedings below. Suffice to say that the case was tried before a jury on
    Wilson’s claims for IIED, negligence, and nuisance as alleged in the first amended
    complaint. All of those claims alleged, in essence, stray voltage generated by the
    Topaz substation entered into Wilson’s home, causing shocks to Wilson, and that
    Edison knew of the stray voltage from the substation, but failed to properly
    operate, maintain, or control the substation, and failed to maintain the safety of the
    residents living next to the substation. Wilson contended at trial that any level of
    stray voltage on the property was unacceptable, and Edison was liable for failing to
    eliminate it.17
    After an eight-day trial, the jury found in favor of Wilson on all three claims.
    The jury awarded Wilson $375,000 in past non-economic damages and $175,000
    in future non-economic damages on her IIED and negligence claims, and $500,000
    17
    For example, during closing argument, Wilson’s attorney highlighted the most
    important evidence to show Edison’s liability: “No. 1, we know that the stray voltage
    problem on Knob Hill is a persistent, recurrent, serious problem that was never fixed.”
    Later, counsel told the jury: “I can tell you that if there was a bunch of voltage on my
    fixtures in my home, I would not say to myself well, gee, I wonder how this registers on
    the IEC chart, physiological chart, or I w[o]nder what the difference in potential between
    my showerhead and my drain. . . . [¶] What I’m thinking is, there is electricity in my
    house, on my fixtures, that people, real human being, including my own children, are
    being exposed to. And that is unacceptable.”
    17
    on her nuisance claim, and found Edison liable for punitive damages. Following a
    punitive damages phase, the jury awarded Wilson $3 million in punitive damages.
    The trial court entered judgment, and Edison timely filed motions for
    judgment notwithstanding the verdict and a new trial. In the motion for judgment
    notwithstanding the verdict, Edison argued for the first time that all of Wilson’s
    claims were barred by Public Utilities Code18 section 1759.19 The trial court
    denied both motions, by minute order and by a signed order. Edison timely filed
    notices of appeal following entry of each order.
    DISCUSSION
    Edison contends that Wilson’s claims fall under the exclusive jurisdiction of
    the PUC, that no substantial evidence supports her claims, that the damages award
    is excessive, and that punitive damages were unjustified. We find that the PUC
    does not have exclusive jurisdiction over Wilson’s claims, but we agree there was
    insufficient evidence to support her IIED and negligence claims and that the
    punitive damages award was unjustified. Although we reject Edison’s contention
    that there was insufficient evidence to support the nuisance claim, we find the jury
    may have relied upon irrelevant evidence in considering that claim, and therefore
    the nuisance claim must be retried.
    18
    Further undesignated statutory references are to the Public Utilities Code.
    19
    Edison had argued in a motion for summary judgment that Wilson’s nuisance
    claim was barred by section 1759, but its argument was premised on its understanding
    that the nuisance claim was based upon Wilson’s fear of harm from electromagnetic
    fields.
    18
    A.    Exclusive Jurisdiction of the PUC
    Section 1759 provides: “No court of this state, except the Supreme Court
    and the court of appeal, to the extent specified in this article, shall have jurisdiction
    to review, reverse, correct, or annul any order or decision of the commission or to
    suspend or delay the execution or operation thereof, or to enjoin, restrain, or
    interfere with the commission in the performance of its official duties, as provided
    by law and the rules of court.” On appeal, Edison argues that Wilson’s claims are
    barred under section 1759 by the PUC’s exclusive jurisdiction over the design,
    siting, operation, and safety of Edison’s electrical distribution system. Wilson
    contends Edison waived this issue by failing to plead it as an affirmative defense in
    the answer or raise it by demurrer, and that, in any event, section 1759 does not
    apply in this case. We conclude that the issue is one of subject matter jurisdiction
    that cannot be waived, but that section 1759 does not bar the trial court from
    litigating Wilson’s claims.
    1. Whether Section 1759 Applies is an Issue of Subject Matter Jurisdiction
    That Cannot Be Waived
    As noted, Edison did not argue that all of Wilson’s claims were barred by
    the PUC’s exclusive jurisdiction until it filed its post-trial motion for judgment
    notwithstanding the verdict. Wilson contends that Edison cannot raise exclusive
    jurisdiction on appeal because “[e]xclusivity is an affirmative defense . . . [that]
    must be pled in the defendant’s Answer—or it is waived.” (Citing Doney v.
    Tambouratgis (1979) 
    23 Cal. 3d 91
    (Doney).) Her reliance upon Doney is
    misplaced.
    
    Doney, supra
    , 
    23 Cal. 3d 91
    , and all but one of the other cases Wilson relies
    upon involve the exclusive remedy provision of the Workers’ Compensation Act
    19
    (Lab. Code, § 3600 et seq.).20 That act provides, in relevant part, that “[w]here the
    conditions of compensation set forth in Section 3600 concur, the right to recover
    compensation is . . . the sole and exclusive remedy of the employee or his or her
    dependents against the employer” (Lab. Code, § 3602, subd. (a)), and that “[i]n all
    cases where the conditions of compensation set forth in Section 3600 do not
    concur, the liability of the employer shall be the same as if this division had not
    been enacted” (Lab. Code, § 3602, subd. (c)). The legal theory supporting this
    exclusive remedy provision “is a presumed ‘compensation bargain,’ pursuant to
    which the employer assumes liability for industrial personal injury or death without
    regard to fault in exchange for limitations on the amount of that liability. The
    employee is afforded relatively swift and certain payment of benefits to cure or
    relieve the effects of industrial injury without having to prove fault but, in
    exchange, gives up the wider range of damages potentially available in tort.”
    (Shoemaker v. Myers (1990) 
    52 Cal. 3d 1
    , 16.)
    As the Supreme Court explained in Doney, “a defendant in a civil action
    who claims to be one of that class of persons protected from an action at law by the
    provisions of the Workers’ Compensation Act bears the burden of pleading and
    proving, as an affirmative defense to the action, the existence of the conditions of
    compensation set forth in the statute which are necessary to its application.
    [Citations.] ‘The employee is pursuing a common law remedy which existed
    before the enactment of the statute and which continues to exist in cases not
    covered by the statute. It is incumbent upon the employer to prove that the
    20
    The remaining case, Crookall v. Davis, Punelli, Keathley & Willard (1998) 
    65 Cal. App. 4th 1048
    , is a legal malpractice case involving the law firm’s failure to timely
    raise the defense of the antideficiency statute in a foreclosure action. (Id. at p. 1056.) It
    has no relevance to the exclusivity issue in this case.
    20
    Workmen’s Compensation Act is a bar to the employee’s ordinary remedy.’
    [Citation.]” (
    Doney, supra
    , 23 Cal.3d at pp. 96-97, fn. omitted.)
    The Supreme Court observed that finding a defendant waived the protection
    of the exclusive remedy provision by failing to raise it as an affirmative defense
    does not “result[] in the improper ‘conferral’ of subject matter jurisdiction by
    means of consent, waiver, or estoppel . . . [because] plaintiff was ‘pursuing a
    common law remedy which existed before the enactment of the statute and which
    continues to exist in cases not covered by the statute.’ [Citation.] The trial court
    clearly had subject matter jurisdiction over such an action unless and until it was
    properly demonstrated that the case was one ‘covered by the statute’ due to the
    presence therein of the conditions of compensation set forth in section 3600 of the
    Labor Code. . . . When, as in this case, no such demonstration has been made . . . ,
    the court properly proceeds to exercise its existing jurisdiction to enforce the
    common law remedy.” (
    Doney, supra
    , 23 Cal.3d at pp. 98-99.)
    In contrast to the workers’ compensation exclusive remedy provision, which
    is designed to protect the employer from tort liability that otherwise could be
    imposed in the absence of the workers’ compensation law, section 1759 is
    designed to protect the PUC’s constitutional and statutory authority to regulate
    utilities. As the Supreme Court explained in San Diego Gas & Electric Co. v.
    Superior Court (1996) 
    13 Cal. 4th 893
    (Covalt), “‘[t]he commission is a state
    agency of constitutional origin with far-reaching duties, functions and powers.
    (Cal. Const., art. XII, §§ 1-6.) The Constitution confers broad authority on the
    commission to regulate utilities, including the power to fix rates, establish rules,
    hold various types of hearings, award reparation, and establish its own procedures.
    (Id. §§ 2, 4, 6.)” 
    (Covalt, supra
    , 13 Cal.4th at pp. 914-915.) The Constitution also
    gives the Legislature plenary power to confer additional authority and jurisdiction
    upon the commission, which the Legislature did by enacting the Public Utilities
    21
    Act (§ 201 et seq.). 
    (Covalt, supra
    , 13 Cal.4th at p. 915.) “That law vests the
    commission with broad authority to ‘supervise and regulate every public utility in
    the State’ (§ 701) and grants the commission numerous specific powers for the
    purpose,” and “further authorized the commission to ‘do all things, whether
    specifically designated in [the Public Utilities Act] or in addition thereto, which
    are necessary and convenient’ in the exercise of its jurisdiction over public utilities.
    [Citation.]” 
    (Covalt, supra
    , 13 Cal.4th at p. 915.)
    In addition to the authority granted directly to the commission by the
    Constitution, “[t]he Constitution also confers plenary power on the Legislature to
    ‘establish the manner and scope of review of commission action in a court of
    record’ (Cal. Const., art. XII, § 5). Pursuant to this constitutional provision the
    Legislature enacted article 3 of chapter 9 of the Public Utilities Act, entitled
    ‘Judicial Review,’ . . . [which] prescribes a method of judicial review that is
    narrow in both ‘manner and scope,’” limiting review of a commission decision to
    an action filed directly in the Supreme Court by means of a petition for writ of
    review.21 
    (Covalt, supra
    , 13 Cal.4th at p. 915.) The Court noted that “the
    Legislature then made it clear in section 1759 of the Public Utilities Act that no
    other court has jurisdiction either to review or suspend the commission’s decisions
    or to enjoin or otherwise ‘interfere’ with the commission’s performance of its
    duties.” 
    (Covalt, supra
    , 13 Cal.4th at p. 916.)
    As this discussion makes clear, section 1759 is a statute involving subject
    matter jurisdiction, and divests trial courts of jurisdiction to entertain lawsuits that
    would interfere with the PUC’s regulation of utilities. Its application cannot be
    waived by the parties to the litigation. (See Harrington v. Superior Court (1924)
    21
    Chapter 9 subsequently was amended to allow for review by the court of appeal in
    addition to the Supreme Court. (§ 1756.)
    22
    
    194 Cal. 185
    , 188 [“Jurisdiction of the subject matter cannot be given, enlarged or
    waived by the parties. . . . ‘[W]here the jurisdiction of the court as to the subject
    matter has been limited by the constitution or statute the consent of parties cannot
    confer jurisdiction.’”].) Indeed, a judgment entered by a court without subject
    matter jurisdiction is void, and may be “‘attacked anywhere, directly or
    collaterally, by parties or by strangers.’” (Marlow v. Campbell (1992) 
    7 Cal. App. 4th 921
    , 928; see also Saffer v. JP Morgan Chase Bank, N.A. (2014) 
    225 Cal. App. 4th 1239
    , 1246 [“Subject matter jurisdiction may be raised for the first
    time on appeal. . . . In addition, an alleged lack of subject matter jurisdiction must
    be addressed whenever it comes to a court’s attention.”].) Therefore, Edison is not
    barred from asserting for the first time on appeal the trial court’s lack of
    jurisdiction under section 1759.
    2.     Section 1759 Does Not Bar Wilson’s Claims
    Having concluded that section 1759 raises an issue of subject matter
    jurisdiction that is not waived by a party’s failure to raise it in its answer or a
    demurrer, we must determine whether that statute bars Wilson’s claims. For that
    we turn to 
    Covalt, supra
    , 
    13 Cal. 4th 893
    , in which the Supreme Court developed a
    three-part test to determine whether section 1759 applies.
    a. The Covalt Test
    In 
    Covalt, supra
    , 
    13 Cal. 4th 893
    , the Supreme Court was required to
    reconcile section 1759 with another provision of the Public Utilities Act, section
    2106, that allowed private actions for damages against public utilities in certain
    circumstances. Section 2106 provides in relevant part that “[a]ny public utility
    which does, causes to be done, or permits any act, matter, or thing prohibited or
    declared unlawful, or which omits to do any act, matter, or thing required to be
    23
    done, either by the Constitution, any law of this State, or any order or decision of
    the commission, shall be liable to the persons or corporations affected thereby for
    all loss, damages, or injury caused thereby or resulting therefrom.”
    The Court noted that in an earlier case in which it had been required to
    reconcile these two provisions for the first time, Waters v. Pacific Telephone Co.
    (1974) 
    12 Cal. 3d 1
    (Waters), it had “declared the primacy of section 1759 and the
    correspondingly limited role of section 2106. The [Waters] court held that ‘in
    order to resolve the potential conflict between sections 1759 and 2106, the latter
    section must be construed as limited to those situations in which an award of
    damages would not hinder or frustrate the commission’s declared supervisory and
    regulatory policies.’” 
    (Covalt, supra
    , 13 Cal.4th at pp. 917-918, quoting 
    Waters, supra
    , 12 Cal.3d at p. 4.) The Covalt court explained that, under the Waters rule,
    an action for damages under section 2106 “is barred by section 1759 not only when
    an award of damages would directly contravene a specific order or decision of the
    commission, i.e., when it would ‘reverse, correct, or annul’ that order or decision,
    but also when an award of damages would simply have the effect of undermining a
    general supervisory or regulatory policy of the commission, i.e., when it would
    ‘hinder’ or ‘frustrate’ or ‘interfere with’ or ‘obstruct’ that policy.” 
    (Covalt, supra
    ,
    13 Cal.4th at p. 918.)
    The Covalt court observed that “[t]he Waters rule may be further understood
    by considering examples of how it has been applied by our Courts of Appeal.
    When the bar raised against a private damages action has been a ruling of the
    commission on a single matter such as its approval of a tariff or a merger, the
    courts have tended to hold that the action would not ‘hinder’ a ‘policy’ of the
    commission within the meaning of Waters and hence may proceed. But when the
    relief sought would have interfered with a broad and continuing supervisory or
    24
    regulatory program of the commission, the courts have found such a hindrance and
    barred the action under section 1759.” 
    (Covalt, supra
    , 13 Cal.4th at pp. 918-919.)
    The Court then turned to the case before it, in which the plaintiffs filed an
    action for damages and injunctive relief against a utility that alleged the utility’s
    powerlines that ran on land adjacent to the plaintiffs’ residence emitted “‘high and
    unreasonably dangerous levels of electromagnetic radiation onto plaintiffs’
    property.’” 
    (Covalt, supra
    , 13 Cal.4th at p. 911.) The Court applied the Waters
    rule by answering three questions: “The first question is whether the commission
    has the authority to adopt a policy on (1) whether electric and magnetic fields
    arising from the powerlines of regulated utilities are a public health risk and (2)
    what action, if any, the utilities should take to minimize that risk” (
    id. at p.
    923);
    “The next question is whether the commission has exercised the foregoing
    authority to adopt a policy on powerline electric and magnetic fields” (
    id. at p.
    926); “The final question is whether the present superior court action would hinder
    or interfere with that policy within the meaning of Waters [citation] and its
    progeny” (
    id. at p.
    935).
    As to the first question, the Court found that “the commission has broad
    authority to determine whether the service or equipment of any public utility poses
    any danger to the health or safety of the public, and if so, to prescribe corrective
    measures and order them into effect.” 
    (Covalt, supra
    , 13 Cal.4th at pp. 923-924.)
    It cited, among other things, section 761 of the Public Utilities Act, which provides
    “that whenever the commission finds that the ‘equipment, appliances, facilities, or
    service of any public utility, or the methods of manufacture, distribution,
    transmission, storage, or supply employed by it’ are ‘unsafe,’ it shall prescribe the
    equipment, appliances, facilities, or service to be provided or used by the utility,
    and shall further prescribe ‘rules for the performance of any service or the
    furnishing of any commodity’ by such utility” 
    (Covalt, supra
    , 13 Cal.4th at p. 924,
    25
    quoting § 761), and section 762, which provides that “whenever the commission
    finds that the equipment, apparatus, or facilities of any utility should be changed or
    improved, or new structures be erected, in order to promote the ‘security’ of its
    employees or the public, it shall order the utility to make such changes or erect
    such structures.” (§ 762; see 
    Covalt, supra
    , 13 Cal.4th at p. 924.)
    As to the next question, the Court noted that the Legislature initiated an
    inquiry into the potential health effects of electromagnetic fields (EMF) caused by
    electrical utility generating and transmission facilities, and directed the
    commission and the State Department of Health Services (DHS) to jointly conduct
    certain high-priority research projects and submit a report on the status of those
    research projects and recommendations, if any, for legislation to limit exposure to
    EMF. 
    (Covalt, supra
    , 13 Cal.4th at p. 926.) The commission and DHS did so, and
    concluded that California should take no action at that time to regulate EMF
    around electric power facilities because such actions would be premature given
    current scientific understanding of the issue. (Id. at p. 927.) Subsequently, the
    commission issued a decision in a proceeding regarding the construction of a new
    transmission line by Southern California Edison Company, in which the
    commission ruled that although it would not adopt standards prescribing maximum
    allowable EMF levels or require any action to be taken to change EMF exposure
    levels along existing transmission lines, it would be prudent to avoid new exposure
    to EMF, and therefore it would require the utility to take certain steps to avoid
    unnecessarily exposing people to EMF. (Id. at p. 928.) A short time later, the
    commission reopened and enlarged its inquiry into the topic of EMF, and
    appointed an advisory panel, which issued a report to the commission
    recommending certain interim actions. (Id. at pp. 929-930.) The commission held
    public hearings on those recommendations and issued an interim opinion and
    order, and ultimately established an EMF policy for electric utility facilities and
    26
    powerlines. (Id. at pp. 930-931.) The Court concluded that “[t]here is no doubt
    that the commission is still actively pursuing the broad policy inquiry into the
    potential health effects of powerline electric and magnetic fields” (
    id. at p.
    934),
    and that “the commission has exercised -- and is still exercising -- its constitutional
    and statutory authority to adopt a general policy on whether electric and magnetic
    fields arising from the powerlines of regulated utilities are a public health risk and
    what steps, if any, the utilities should take to minimize that risk” (
    id. at p.
    935).
    As to the final question, the Court concluded that most of the plaintiffs’
    claims failed to allege facts sufficient to state a cause of action, and the remaining
    claim, for nuisance, was barred by section 1759 because it would hinder or
    interfere with the commission’s policy. Addressing the nuisance claim, the Court
    noted that to award damages for nuisance under a theory that EMF impaired the
    use and enjoyment of the property because plaintiffs feared that EMF would cause
    them physical harm, the trier of fact would be required to find that a reasonable
    person viewing the matter objectively would experience a substantial fear that
    EMF cause physical harm and would deem the invasion so serious that it
    outweighs the social utility of the utility’s conduct. The Court found that those
    findings would be inconsistent with the commission’s conclusion that the available
    evidence does not support a reasonable belief that the EMF in question present a
    substantial risk of physical harm and that regulated utilities need take no action to
    reduce EMF levels from existing powerlines. (Id. at p. 939.)
    b. Application of the Covalt Test
    In applying the Covalt test to this case, Edison argues that (1) the PUC has
    broad authority “to regulate the design, siting, operation, and safety of electrical
    distribution systems”; (2) the PUC has exercised that authority by issuing
    regulations that “include detailed design, construction, operating, and safety
    27
    specifications for every possible aspect of electric distribution systems (e.g., G.O.
    95 [construction of overhead systems]; G.O. 128 [construction of underground
    systems]; G.O. 165 [inspection requirements]; G.O. 131-D [planning and
    construction of electric generation, transmission and distribution facilities]; G.O.
    174 [substations] . . .)”; and (3) the jury award obstructs and interferes with the
    PUC’s regulations and policy by “imposing liability on Edison for stray voltage
    that results from Edison’s compliance with those regulations” and “effectively
    finding that Edison was required to do something—‘completely eliminate[]’ stray
    voltage—that the PUC does not require.”
    The PUC itself offered a similar analysis in an amicus brief filed at the
    request of the trial court in two consolidated cases filed by Wilson’s neighbors
    against Edison based on allegations of stray voltage in the areas surrounding the
    Topaz substation.22 23 First, the PUC argued that the commission “has authority to
    adopt regulatory policies and programs regarding the design, construction,
    22
    The amicus brief was filed in the consolidated cases Daniel Richmond, et al. v.
    Southern California Edison Company (L.A.S.C. Case No. BC497689) and Lori Barber,
    et al. v. Southern California Edison Company (L.A.S.C. Case No. YC066729). We
    granted Edison’s request to take judicial notice of the amicus brief, which was filed on
    June 23, 2014, after Edison filed its appellant’s opening brief; Edison’s request was made
    before Wilson’s respondent’s brief was due. According to the amicus brief, the
    consolidated cases asserted claims based upon allegations that Edison “violated
    Commission General Order (‘GO’) 95, Rule 33.2 by allowing electric current to escape
    from its confines using the ground as a conductor” as well as other claims related to
    alleged excessive EMF radiation at the Topaz substation.
    23
    We recognize that the question whether the PUC has exclusive jurisdiction is a
    legal question, and we are not bound by the PUC’s determination. (See, e.g., PG&E
    Corp. v. Public Utilities Com. (2004) 
    118 Cal. App. 4th 1174
    , 1195 [“[I]n deciding this
    issue we necessarily take into account the PUC’s interpretation of the statutes it is
    charged to administer, mindful that the PUC’s interpretation is not controlling but is
    accorded weight commensurate with the thoroughness, validity, and consistency of the
    PUC’s reasoning. The PUC’s interpretation is one of ‘among several tools available to
    the court’ in determining the meaning and legal effect of a statute.”].)
    28
    operation, and maintenance and safety of utility equipment and facilities.” Next, it
    argued that the commission exercised its authority by “adopting various regulatory
    policies and programs governing the design, construction, maintenance, operation,
    and safety of the equipment and facilities such as those at issue in this case,”
    noting that those policies and programs “are reflected in various Commission
    orders, decisions, rules, and regulations,” such as the rules and requirements set
    forth in General Order (G.O.) 131-D, G.O. 95, and G.O. 128. In addition, the PUC
    noted that its “regulatory policies and programs in this area are continuing and
    ongoing,” citing the frequent amendments to G.O. 95 and the adoption in 2012 of
    G.O. 174, “containing ‘Rules for Electric Utility Substations.’” Finally, the PUC
    argued that court adjudication prior to a commission finding of wrongdoing
    “would interfere with the Commission’s authority to interpret and apply its own
    orders, decisions, rules and regulations regarding the design, construction,
    operation, maintenance and safety of utility equipment and facilities.” The
    commission noted that its “regulatory programs ensure, among other things, that
    regulated utilities will be subject to uniform requirements,” and that a trial court’s
    determination of the issues in the consolidated cases could “unintentionally result
    in new or inconsistent requirements regarding the design, construction, operation,
    maintenance, and safety of utility equipment and facilities.”
    In contrast to Edison’s and the PUC’s analysis, Wilson in her respondent’s
    brief focuses only on the second question, and appears to argue that section 1759
    applies only if “the PUC exercised its authority to specifically regulate the specific
    conduct for which the plaintiff sought civil damages.” She contends that because
    there is no regulation on stray voltage, Edison fails the Covalt test.
    We disagree with Wilson’s assertion that section 1759 applies in this case
    only if the PUC has issued a specific regulation on stray voltage. In Covalt, the
    Court observed that under the Waters rule, section 1759 barred an action for
    29
    damages “not only when an award of damages would directly contravene a specific
    order or decision of the commission, . . . but also when an award of damages
    would simply have the effect of undermining a general supervisory or regulatory
    policy of the commission, i.e., when it would ‘hinder’ or ‘frustrate’ or ‘interfere
    with’ or ‘obstruct’ that policy.” 
    (Covalt, supra
    , 13 Cal.4th at p. 918, italics added.)
    But we also disagree with Edison’s (and the PUC’s) assertion that the
    commission’s adoption of various policies governing the design, construction,
    maintenance, operation, and safety of electrical distribution facilities is sufficient
    to establish the PUC’s exclusive jurisdiction over the claims in this case.24
    As Wilson correctly points out, it is not sufficient that the PUC issued
    general regulations requiring that electrical distribution systems be operated and
    maintained in a manner to ensure safety and service, and setting forth certain
    design requirements. Indeed, the Supreme Court in Covalt cited with approval
    Pierce v. Pacific Gas & Electric Co. (1985) 
    166 Cal. App. 3d 68
    , in which the
    appellate court held that section 1759 did not bar the plaintiff’s action for damages
    caused by a defective transformer that exploded and sent 7,000 volts of electricity
    into house wiring designed to carry 120 volts. The Supreme Court noted the
    appellate court properly rejected “a contention that the superior court lacked
    jurisdiction under the Waters rule simply because a general regulation (Gen. Order
    No. 95) provides that electric supply systems shall be maintained in such a
    condition as to give ‘safe’ service and utilities shall ‘exercise due care to reduce to
    24
    There can be no dispute that the PUC has the authority to adopt a policy on safety
    issues, including stray voltage, arising from the operation of the Topaz substation. As the
    Supreme Court stated in Covalt, “the commission has broad authority to determine
    whether the service or equipment of any public utility poses any danger to the health or
    safety of the public, and if so, to prescribe corrective measures and order them into
    effect.” 
    (Covalt, supra
    , 13 Cal.4th at pp. 923-924.)
    30
    a minimum’ the hazards from overhead wires.” 
    (Covalt, supra
    , 13 Cal.4th at p.
    945.)
    Edison, however, does not solely rely upon the general safety and design
    regulations issued by the PUC. As Edison explains, those regulations specifically
    address grounding, including grounding requirements for common neutral systems
    like the Topaz system. (G.O. 95, Rules 21.4, 33.3, 58.2, 59.4.) Those regulations
    require that grounding be “effective” (G.O. 95, Rule 21.4) and set forth detailed
    minimum requirements for ground conductors (G.O. 95, Rules 33.3, 59.4).
    Because the PUC expressly requires that electrical distribution systems be
    grounded, and because (as even Wilson’s expert witness testified at trial) stray
    voltage is an inevitable byproduct of grounding, Edison argues that Wilson’s
    lawsuit – which imposes liability on Edison for damages resulting from this
    byproduct – contravenes the PUC’s grounding regulations because Edison cannot
    comply with those regulations while also satisfying Wilson’s demand that it
    completely eliminate stray voltage on her property.25
    Our review of the General Orders Edison cites and the cases in which PUC
    exclusive jurisdiction was found lead us to conclude, however, that the Covalt test
    is not satisfied here.
    First, although there is no doubt that the General Orders require grounding
    of substations, it may be that Edison could comply with the regulations and still
    mitigate the stray voltage that results from grounding. Although that is an issue
    that is more appropriately submitted to the PUC under the primary jurisdiction
    doctrine (see Farmers Ins. Exchange v. Superior Court (1992) 
    2 Cal. 4th 377
    , 390-
    391 [when a claim is originally cognizable in the courts, primary jurisdiction
    25
    Edison notes that Wilson testified that mitigation of touch potential by bonding or
    installing insulators would be insufficient because the stray voltage would not be
    eliminated.
    31
    “‘comes into play whenever enforcement of the claim requires the resolution of
    issues which, under a regulatory scheme, have been placed within the special
    competence of an administrative body; in such a case the judicial process is
    suspended pending referral of such issues to the administrative body for its
    views’”]), it does not mean that Wilson’s claims are barred under the Covalt test.
    Second, when the PUC adopted G.O. 174, entitled “Rules for Electric Utility
    Substations,” the commission explained why it was needed: “The Commission’s
    current General Orders 95, 128, and 165 are already designed to promote safe
    operation of electric utility and communications infrastructure facilities, and
    provide minimum safety requirements which the utilities are to supplement with
    additional safety precautions when local conditions warrant. However, these
    General Orders do not give guidance as to how utilities operate and maintain their
    substations, and there are no specific regulations governing substation operation.”
    (Order Instituting Rulemaking to Implement Com. Regs. Re Safety of Electric
    Utility Substations (Oct. 25, 2012) 2012 Cal. PUC LEXIS 470, *2, italics added.)
    G.O. 174 does not, however, contain any such regulations. Instead, the General
    Order requires each electric utility to establish and update an inspection program
    for its substations, maintain records of its inspections, and submit annual
    inspection program summaries and reports summarizing completed inspections to
    the Utilities Safety and Reliability Branch of the PUC. (G.O. 174, Rules 30, 31,
    32, 33, 40.) And although the PUC ordered the utilities to meet annually to share
    their newly developed practices and review their own practices in light of other
    utilities’ practices, with the expectation that “a ‘best practice’ will evolve that
    shows how to most effectively operate and safely control the electric systems in
    California . . . even as these practices continue to reflect the unique elements of
    each system” (Order Instituting Rulemaking to Implement Com. Regs. Re Safety of
    Electric Utility 
    Substations, supra
    , 2012 Cal. PUC LEXIS 470, at p. *10), it is
    32
    unclear whether this “best practice” will address stray voltage issues. Therefore,
    we cannot say with any certainty that litigation of Wilson’s claims would hinder or
    interfere with the PUC’s regulatory policy.
    Finally, the purported exercise of authority that Edison relies upon is of a
    vastly different character than the kinds of exercise of authority found in cases in
    which courts applied the Waters rule and found that section 1759 bars the
    plaintiff’s action. In most of those cases, the PUC conducted (or was in the
    process of conducting) investigations into or adopted regulations on the specific
    issue alleged in the plaintiffs’ lawsuit. (See, e.g., 
    Covalt, supra
    , 
    13 Cal. 4th 893
    [plaintiffs alleged damages due to defendant’s powerlines emitting EMF radiation
    on plaintiffs’ property; PUC conducted research projects on and investigations into
    the potential health effects of EMF]; Sarale v. Pacific Gas & Electric Co. (2010)
    
    189 Cal. App. 4th 225
    [plaintiffs sought damages and injunctive relief based on a
    utility’s alleged excessive trimming of commercially productive walnut trees
    located under the utility’s power lines; the commission had adopted a regulation
    mandating minimum distances that must be maintained between conductors and
    vegetation, expressly declined to mandate the maximum limits of tree trimming,
    and left to the determination of the utility whether greater clearance were necessary
    under the circumstances to accomplish the purposes of the regulation]; Brian T. v.
    Pacific Bell (1989) 
    210 Cal. App. 3d 894
    [plaintiffs sought damages and injunction
    to compel utility to restrict access of sexually explicit materials to adults through
    certain methods; commission had conducted investigation and hearings on how to
    restrict access and adopted a different method]; Schell v. Southern Cal. Edison Co.
    (1988) 
    204 Cal. App. 3d 1039
    [owner of an RV park filed action alleging his RV
    park was entitled to residential baseline gas and electricity allocations; proceedings
    were pending before the commission on whether RV parks should come under a
    special rate schedule for provision of baseline service].)
    33
    In light of the absence of any indication that the PUC has investigated or
    regulated the issue of stray voltage, and without any evidence that stray voltage
    cannot be mitigated without violating the PUC’s regulation requiring grounding,
    we cannot say that Wilson’s lawsuit would interfere with or hinder any supervisory
    or regulatory policy of the PUC. Therefore, we hold that Wilson’s claims are not
    within the exclusive authority of the PUC under section1759.
    C.    Sufficiency of the Evidence
    In its appellant’s opening brief, Edison argued there was insufficient
    evidence to support Wilson’s claims, focusing on specific elements in each cause
    of action that Edison asserted Wilson failed to prove. Wilson did not respond
    directly to Edison’s arguments in her respondent’s brief, and did not address at all
    the elements of her claims. Instead she asserted that Edison ignored the evidence
    of Edison’s conduct before Wilson purchased her home, and gave too little weight
    to the experiences of previous tenants and the evidence of Wilson’s emotional
    distress. We have examined the evidence presented at trial and conclude that
    Wilson failed to present sufficient relevant evidence to establish the elements of
    her IIED and negligence claims. We cannot conclude there was insufficient
    evidence to support Wilson’s nuisance claim, since it requires the jury to balance
    the gravity of the harm from the interference with Wilson’s use and enjoyment of
    her property against the social utility of Edison’s conduct. Nevertheless, we hold
    that judgment with respect to that claim must be reversed and remanded for retrial
    because the jury considered evidence of Wilson’s physical injuries (which should
    not have been considered because there was no evidence those injuries were
    caused by her exposure to stray voltage) in balancing the harm against the social
    utility and finding in favor of Wilson.
    34
    1.     IIED
    Edison contends there was no substantial evidence that it engaged in any
    extreme or outrageous conduct directed at Wilson, and therefore Wilson could not
    recover on her IIED claim. We agree.
    “The elements of the tort of intentional infliction of emotional distress are:
    ‘“(1) extreme and outrageous conduct by the defendant with the intention of
    causing, or reckless disregard of the probability of causing, emotional distress;
    (2) the plaintiff’s suffering severe or extreme emotional distress; and (3) actual and
    proximate causation of the emotional distress by the defendant’s outrageous
    conduct. . . .” Conduct to be outrageous must be so extreme as to exceed all
    bounds of that usually tolerated in a civilized community.’ . . . [¶] It is not enough
    that the conduct be intentional and outrageous. It must be conduct directed at the
    plaintiff, or occur in the presence of a plaintiff of whom the defendant is aware.”
    (Christensen v. Superior Court (1991) 
    54 Cal. 3d 868
    , 903 (Christensen).)
    Wilson’s theory at trial was that Edison had known for more than 20 years
    that there was stray voltage at the property Wilson purchased in 2007, that the level
    of stray voltage was dangerous, as evidenced by the physical injuries Wilson
    suffered, and that Edison’s decision to put the property on the market, its failure to
    eliminate the stray voltage, and its failure to warn Wilson caused Wilson extreme
    emotional distress due to her physical injuries and her fear of harm to herself and
    her children.26 Had the evidence at trial demonstrated that the level of stray
    voltage was dangerous and caused Wilson’s physical injuries, we might conclude
    the jury’s finding that Edison’s conduct was outrageous was supported by the
    evidence. But there was no such evidence.
    26
    Wilson’s counsel confirmed at oral argument that Wilson’s emotional distress was
    due in large part to her distress over her physical symptoms.
    35
    To be sure, Wilson presented evidence of various physical ailments she
    suffered, as well as evidence that she did not begin to suffer those ailments until
    after she remodeled her master bathroom and began to feel electricity in the
    shower. Wilson did not, however, present any competent evidence showing that
    those physical ailments were caused by her exposure to the stray electricity at her
    house.
    Although Wilson testified that a neurologist she went to in May 2011, Dr.
    Rederich, told her she had severed her nerve endings and that she might be
    developing secondary erythromelalgia, she also testified that Dr. Rederich could
    not definitively say what was causing her symptoms. Moreover, the specialist to
    whom Dr. Rederich sent Wilson, Dr. Beydoun, testified that Wilson did not, in
    fact, have any nerve damage or secondary erythromelalgia, and that he did not
    know the cause of her symptoms. Finally, Edison presented the testimony of an
    expert witness – the former chairman of the department of neurology of Yale
    Medical School, Dr. Waxman – who testified that he is not aware of any evidence
    that intermittent contact with low voltage electricity can cause any kind of nerve
    damage or erythromelalgia. In fact, he testified that electricity (at levels from
    10mA to 120mA) is administered to patients in a number of ways within the
    medical profession, including when administering nerve conduction tests, such as
    were performed on Wilson.
    Without expert testimony linking her physical symptoms to her exposure to
    stray voltage, Wilson could not rely upon those symptoms as evidence that Edison
    allowed dangerous levels of stray voltage on her property. (See Jones v. Ortho
    Pharmaceutical Corp. (1985) 
    163 Cal. App. 3d 396
    , 402 [“The law is well settled
    that in a personal injury action causation must be proven within a reasonable
    medical probability based upon competent expert testimony”]; see also 
    id. at p.
    403
    [“‘[I]n the absence of factual circumstances of probability understandable to a jury
    36
    there must be some scientific testimony that can be interpreted as an inference of
    hypothetical probability before we can allow a jury to speculate upon the rights of
    citizens. [¶] . . . If the experts cannot predict probability in these situations, it is
    difficult to see how courts can expect a jury of laymen to be able to do so”].) In
    fact, Edison had requested a jury instruction based upon the language in Jones, but
    Wilson objected to the instruction, and the court refused to give it on the grounds
    that Wilson was asking only for general damages, and not special damages.27
    While we acknowledge that Wilson did not seek to recover special damages for her
    physical injuries, she clearly relied upon evidence of those injuries in attempting to
    show both that the level of stray voltage at her house was dangerous and that she
    suffered emotional distress due to those injuries. Therefore, she was required to
    establish that those injuries were caused by her exposure to stray voltage, and the
    trial court erred in refusing Edison’s proposed instruction. Because Wilson did not
    present any evidence to establish the causal connection, we conclude that she failed
    to present sufficient evidence to support her IIED claim to the extent she relied
    upon her physical symptoms to show that Edison’s conduct was outrageous.
    To the extent Wilson contends the evidence she presented regarding stray
    voltage at her gas meter -- i.e., evidence that the gas company tagged her meter and
    turned off her gas service for a weekend in August 2008, and tagged her meter
    again in April 2010 -- establishes that the level of stray voltage on her property was
    dangerous, that evidence is insufficient to establish outrageous conduct by Edison.
    First, the fact that the gas company restored service when Edison explained that the
    27
    Edison’s proposed jury instruction stated: “In a personal injury action, causation
    must be proven within a reasonable medical probability based upon competent expert
    testimony. A possible cause only becomes probable when, in the absence of other
    reasonable causal explanations, it becomes more likely than not that the injury was a
    result of the defendant’s action.”
    37
    source of the voltage probably was NEV tends to show that any danger from the
    voltage on Wilson’s gas meter was not significant. Moreover, the evidence
    showed that Edison worked with the gas company to determine the best way to
    minimize the stray voltage at the gas meter, and ultimately paid to have the gas
    company install isolators throughout the neighborhood, which reduced the voltage
    on Wilson’s meter to nearly zero. Thus, a finding of outrageous conduct by Edison
    cannot be based upon Wilson’s allegation that Edison allowed dangerous levels of
    stray voltage onto Wilson’s property.
    Even if it could be found that a decision to put a property on the market
    when the levels of stray voltage were enough to perceive but were not dangerous
    constituted outrageous conduct, the evidence presented at trial was insufficient to
    hold Edison liable for IIED. Before Edison authorized the release of the property
    for sale in 1998, it investigated the source of shocks and found a problem on a
    nearby distribution pole; when that problem was fixed, the stray voltage at the
    house stopped. Edison’s sales and leasing manager went to the house and touched
    the areas that previously had produced shocks to verify there were no more shocks.
    After the property was sold in 1999, there were no reports of shocks for the next
    five years. Thus, the evidence showed that Edison reasonably believed at the time
    of the sale that it had eliminated the potential for shocks. And when Edison
    received a report of shocks in 2004, it thoroughly investigated the situation,
    conducted simulations, and implemented a plan to install a common neutral
    system. After the system was installed, Edison confirmed with the tenants that
    they were satisfied with the results, and Edison received no more complaints of
    shocks or stray voltage until Wilson’s gas meter was tagged in 2008.
    In short, the evidence presented at trial showed that Edison believed it had
    eliminated the potential for shocks when it put the house on the market in 1998-
    1999. When it received a report of shocks five or six years later, it responded by
    38
    installing a common neutral system, which appeared to fix the problem. When it
    received reports of electricity at Wilson’s gas meter several years later, it
    responded by working with the gas company to find a solution and paying for the
    installation of isolators on all of the gas service lines in the neighborhood. Finally,
    when it received the report that Wilson was experiencing an electrical current in
    her newly remodeled shower, Edison came to the house, took measurements to
    determine the level of electricity was not dangerous, explained how the current
    could be eliminated by installing isolators or bonding the fixture and the drain, and
    offered to pay for the installation of the isolators. This evidence is insufficient to
    establish that Edison’s conduct was “‘so extreme as to exceed all bounds of that
    usually tolerated in a civilized community.’”28 
    (Christensen, supra
    , 54 Cal.3d at p.
    903.) Therefore, the judgment in favor of Wilson on her IIED claim must be
    reversed.
    2.     Negligence
    To establish liability for Edison’s negligence, Wilson was required to
    present evidence that Edison owed a duty to Wilson, that Edison breached that
    duty, and that Edison’s breach was a proximate cause of the harm Wilson suffered.
    (Federico v. Superior Court (1997) 
    59 Cal. App. 4th 1207
    , 1210-1211.) Edison
    contends Wilson failed to establish any breach of duty. We agree.
    Wilson attempted to establish a breach of a duty by Edison through the
    testimony of her expert witness, electrical engineer Douglas Bennett. Bennett
    28
    To the extent Wilson relies upon her testimony that an Edison claims
    representative yelled at her during the May 6, 2011 meeting at her house when she
    described her symptoms, that evidence is insufficient to establish liability for IIED. (See
    Hughes v. Pair (2009) 
    46 Cal. 4th 1035
    , 1051 [“Liability for intentional infliction of
    emotional distress ‘“does not extend to mere insults, indignities, threats, annoyances,
    petty oppressions, or other trivialities”’”].)
    39
    testified that Edison violated standards in the electrical distribution industry in the
    way it designed its distribution system at the Topaz substation, but he did not know
    what was wrong with the design. He also stated that Edison violated standards by
    allowing dangerous levels of electricity to be present at Wilson’s home, although
    he could not state what constitutes a dangerous level. When asked why he
    believed Edison had not complied with its duties and responsibilities as a
    distributor of electricity, he said, “[b]ecause the voltage still exists at the property.
    And that’s not right. . . . [¶] [Wilson is] being subjected to these voltages. They
    are totally out of her control. They can only be addressed by the Edison Company
    to reduce the voltage present at her house.”
    Given the undisputed evidence that stray voltage is an unavoidable
    byproduct of grounding, which is required by the PUC, it cannot be the case that
    Edison breached a duty owed to Wilson by failing to eliminate all stray voltage at
    Wilson’s house, whether perceived or not. Moreover, because the only injury
    Wilson claimed in her lawsuit was emotional distress,29 she was required to show
    that Edison’s breach threatened physical injury to her. (See Potter v. Firestone
    Tire & Rubber Co. (1993) 
    6 Cal. 4th 965
    , 984-985 (Potter) [“[T]here is no
    independent tort of negligent infliction of emotional distress. [Citation.] The tort
    is negligence, a cause of action in which a duty to the plaintiff is an essential
    element. [Citations.] That duty may be imposed by law, be assumed by the
    defendant, or exist by virtue of a special relationship.”] “[U]nless the defendant
    has assumed a duty to plaintiff in which the emotional condition of the plaintiff is
    29
    Wilson’s counsel made clear in his closing argument to the jury that the harm for
    which Wilson sought to hold Edison liable was the emotional distress she suffered as a
    result of Edison’s conduct. He told the jury, “So what I’m asking for is for damages and
    what’s called general damages, anxiety, emotional distress, the inconvenience, the items
    that are on the verdict form that are – essentially these are the nonfinancial damages.
    What I’m asking for is for emotional distress for the past and for the future.”
    40
    an object, recovery is available only if the emotional distress arises out of the
    defendant’s breach of some other legal duty and the emotional distress is
    proximately caused by that breach of duty. Even then, with rare exceptions, a
    breach of the duty must threaten physical injury, not simply damage to property or
    financial interests.” 
    (Potter, supra
    , 6 Cal.4th at p. 985.) Thus, at the very least,
    there could not have been a breach of duty during the period when no shocks were
    felt on the property.30
    Even if we assume that exposure to low voltage shocks could threaten
    physical injury (despite the absence of evidence that the physical injuries Wilson
    suffered were caused by that exposure, and the testimony of Edison’s expert that
    such exposure does not cause physical injury), there is no evidence that Edison
    breached any duty of care in this case. As noted, the evidence showed that Edison
    had eliminated the touch potential in the house in 2005, inasmuch as there were no
    reports of shocks from that time until Wilson remodeled her bathroom in 2011.
    That remodel created touch potential in her shower because the water pipes she
    installed were metal and the drain was connected to the ground. Once she reported
    the problem to Edison, Edison owed her a duty to eliminate the touch potential.
    The evidence shows that Edison explained to Wilson (and her boyfriend) what
    needed to be done to eliminate the touch potential, and offered to pay for the
    installation of plastic isolators. Wilson, however, refused Edison’s offer, insisting
    that Edison had to eliminate all stray voltage on her property. In light of this
    30
    Although it might be argued that the stray voltage found at Wilson’s gas meter
    could demonstrate a potential threat of physical injury to the extent it could cause an
    explosion, the evidence showed that Edison acted to eliminate that threat. It responded to
    the reports of voltage by explaining to the gas company that the voltage was NEV and
    agreeing to monitor it (which appeared to address the gas company’s concern about any
    possible danger), and then paid for the installation of isolators on the service lines (which
    virtually eliminated the voltage).
    41
    evidence, we conclude that Wilson failed to present sufficient evidence to support
    her negligence claim because she failed to establish any breach of a duty by Edison
    that threatened physical injury to her.
    3.     Nuisance
    Edison contends the judgment on Wilson’s nuisance claim must be reversed
    because the claim is precluded under Civil Code section 3482, which provides that
    “[n]othing which is done or maintained under the express authority of a statute can
    be deemed a nuisance.” According to Edison, because the undisputed evidence
    establishes that the stray voltage Wilson experienced is an unavoidable byproduct
    of grounding, and the substation’s grounding is both required by and fully
    compliant with PUC regulations, Civil Code section 3482 applies.
    In making this argument, Edison relies upon Farmers Ins. Exchange v. State
    of California (1985) 
    175 Cal. App. 3d 494
    (Farmers). In that case, plaintiff
    insurance companies sought damages for automobile paint corrosion caused by the
    state’s pesticide spraying for medfly eradication. Rejecting the plaintiffs’
    argument that Civil Code section 3482 did not apply because the law at issue “did
    not ‘expressly authorize’ the state to damage automobile paint finishes,” the
    appellate court stated: “This misses the point. The authorizing statute need not
    predict the precise nature of the damages. It need only authorize the governmental
    action.” (Id. at p. 503.) Edison argues that in this case, “the PUC need not have
    ‘expressly authorized’ stray voltage to exist on properties around a utility’s
    electrical distribution infrastructure, . . . [i]t need only -- as it did -- impose the
    design, siting, operation, and safety requirements for Edison’s electrical
    distribution system, including grounding, with which Edison complied.”
    Edison’s reliance on 
    Farmers, supra
    , 
    175 Cal. App. 3d 494
    is misplaced. As
    the Supreme Court explained in Varjabedian v. City of Madera (1977) 
    20 Cal. 3d 42
    285 (Varjabedian), “‘“[a] statutory sanction cannot be pleaded in justification of
    acts which by the general rules of law constitute a nuisance, unless the acts
    complained of are authorized by the express terms of the statute under which the
    justification is made, or by the plainest and most necessary implication from the
    powers expressly conferred, so that it can be fairly stated that the legislature
    contemplated the doing of the very act which occasions the injury.”’ . . . A
    requirement of ‘express’ authorization embodied in the statute itself insures that an
    unequivocal legislative intent to sanction a nuisance will be effectuated, while
    avoiding the uncertainty that would result were every generally worded statute a
    source of undetermined immunity from nuisance liability.” (Id. at p. 291.)
    Applying this standard in the case before it, which involved a nuisance claim based
    upon odors emitted from the defendant city’s operation of a waste water treatment
    plant, the Supreme Court rejected the city’s argument that “the general
    authorization of municipal construction of sewage plants ‘expressly’ sanctions the
    production of any particular level of odors within the meaning of [Civil Code]
    section 3482.” 
    (Varjabedian, supra
    , 20 Cal.3d at p. 292.) The Court observed:
    “None of the Government Code statutes under which the city claims to act
    mentions the possibility of noxious emanations from such facilities. Nor can we
    find that such odors were authorized by the ‘plainest and most necessary
    implication’ from the general powers there conferred, or that it can be fairly said
    that the Legislature contemplated, to any extent, the creation of a malodorous
    nuisance when it authorized sewage plant construction. Indeed, one object of such
    plants is to remove harmful and obnoxious effluents from the environment.”
    (Ibid.)
    The appellate court in Farmers distinguished the Supreme Court’s decision
    in Varjabedian on the grounds that the nuisance complained of in Farmers, “the
    release of a chemically destructive spray into the atmosphere, was precisely what
    43
    was authorized by the various statutes [at issue].” (
    Farmers, supra
    , 175
    Cal.App.3d at p. 503.) The same cannot be said in this case. Rather, the nuisance
    complained of here is similar to the nuisance complained of in Varjabedian, i.e., a
    byproduct of a facility constructed in accordance with statutes or regulations
    authorizing such facilities. Therefore, we find that Civil Code section 3482 does
    not preclude Wilson’s nuisance claim.
    Although we reject Edison’s argument that Civil Code section 3482
    precludes Wilson’s nuisance claim, we cannot affirm the judgment on that claim. 31
    As we have explained, Wilson presented substantial evidence of various
    physical injuries she suffered, but failed to show that any of those injuries were
    caused by her exposure to stray voltage. In fact, the undisputed expert evidence
    established that exposure to that level of electricity would not cause injury. While
    we do not doubt that Wilson suffered from the symptoms she described, they were
    irrelevant to her claims in the absence of any showing of a causal connection
    between the symptoms and her exposure to stray voltage.32 It appears, however,
    that the jury considered Wilson’s injuries in reaching its verdict on at least one of
    31
    After oral argument, we asked the parties for briefing on whether the nuisance
    claim should be reversed and remanded on the grounds that (1) it cannot be determined
    whether the jury considered irrelevant evidence when determining whether the
    seriousness of the harm to Wilson outweighed the public benefit of Edison’s conduct; and
    (2) the jury was not instructed on the factors it was to consider to determine whether the
    seriousness of the harm to Wilson outweighed the public benefit of Edison’s conduct.
    We have received and considered the supplemental briefing from both parties.
    32
    We emphasize that Wilson’s theory at trial was that she suffered emotional
    distress as a result of physical symptoms purportedly caused by stray voltage, not that the
    stray voltage caused her emotional distress, which then caused the physical symptoms.
    In any event, she did not present any competent evidence that the symptoms she
    described could have resulted from emotional distress.
    44
    her claims, because it asked the court for a read back of Wilson’s testimony
    “regarding her symptoms and the dates of symptoms, doctor’s visits, et cetera.”
    There is no doubt that the jury considered this irrelevant evidence in
    deciding the nuisance claim. The jury was instructed to determine whether Wilson
    was harmed by Edison’s conduct and whether the seriousness of the harm
    outweighed the public benefit of Edison’s conduct.33 We acknowledge that to
    recover on a nuisance claim the harm the plaintiff suffers need not be a physical
    injury. (See, e.g., Acadia, California, Ltd. v. Herbert (1960) 
    54 Cal. 2d 328
    , 337
    [“regardless of whether the occupant of land has sustained physical injury, he may
    recover damages for the discomfort and annoyance of himself and the members of
    his family and for mental suffering occasioned by fear for the safety of himself and
    his family when such discomfort or suffering has been proximately caused by a
    trespass or a nuisance”]; Stoiber v. Honeychuck (1980) 
    101 Cal. App. 3d 903
    , 919
    [“The statutory definition of nuisance appears to be broad enough to encompass
    almost any conceivable type of interference with the enjoyment or use of land or
    property”]; Civ. Code, § 3479 [“Anything which is injurious to health, . . . or is
    indecent or offensive to the senses, or an obstruction to the free use of property, so
    33
    The jury was given CACI No. 2021, which instructed that, to establish her
    nuisance claim, “Wilson must prove all of the following: [¶] No. 1, that Southern
    California Edison Company by acting, or failure to act, created a condition or permitted a
    condition to exist that was harmful to [health, indecent] or offensive to the senses, or was
    an obstruction to the free use of property, so as to interfere with the comfortable
    enjoyment of life or property. [¶] No. 2, that this condition interfered with Simona
    Wilson’s use or enjoyment of her property. [¶] No. 3, that Simona Wilson did not
    consent to Southern California Edison Company’s conduct. [¶] No. 4, that an ordinary
    person would be reasonably annoyed or disturbed by Southern California Edison
    Company’s conduct. [¶] No. 5, that Simona Wilson was harmed. [¶] No. 6, that
    Southern California Edison Company’s conduct was a substantial factor in causing
    Simona Wilson harm; and [¶] No. 7, that the seriousness of the harm outweighed the
    public benefit of Southern California Edison Company’s conduct.”
    45
    as to interfere with the comfortable enjoyment of life or property . . . is a
    nuisance”].) Thus, the absence of evidence in this case to establish that Wilson’s
    physical injuries were caused by the stray voltage would not preclude recovery on
    her nuisance claim.
    Nevertheless, the jury’s verdict on the claim cannot stand because under
    Wilson’s theory of the case, those physical injuries were an integral part of the
    harm she purportedly suffered. For example, when explaining to the jury that it
    needed to determine how to compensate Wilson for her damages in the lawsuit,
    counsel for Wilson told the jury: “[Y]ou have to identify what are the harms and
    losses that were caused by Edison. . . . Ms. Wilson discovered on April 20th that
    there was electricity on her line. That date started an absolute nightmare for her
    and her family. She went to her doctor, to a neurologist, and was told that she had
    nerve damage which set off a chain of months and months and even years of tests,
    every blood test know[n] to mankind, skin biopsies, nerve conduction studies, over
    and over and over again. Specialist. Taking her kids to the doctor to make sure
    they are okay. [¶] She had to eventually leave the house. She was told by her
    inspector who was the only person not attached to Edison, get out of the house
    immediately. She couldn’t afford to keep paying the mortgage on this house and to
    live in another place. Her credit was destroyed. She has been -- she’s gone
    through all this emotional distress with her kids in that house. They see it. She’s
    worried about them. Are they feeding off me. It is absolutely a disaster.” When
    counsel later specifically addressed damages for her nuisance claim, counsel
    referred back to his earlier discussion of Wilson’s “nightmare,” stating: “What is
    the amount to compensate Ms. Wilson for interference with her use and enjoyment
    of her property. Ms. Wilson has -- basically from April 19 through today or
    through when she moved out [of her] house, that home was essentially rendered
    useless. . . . [¶] Having electricity all over your fixtures, it effectively destroyed
    46
    her use and enjoyment of the home. I mean, what else can I say. It’s a nightmare
    and we’ve gone through that. So I’m going to ask for $500,000 for the nuisance
    claim.” Counsel then discussed Wilson’s physical symptoms, and argued that all
    of the doctors who testified acknowledged that her symptoms were real. Because
    the evidence of Wilson’s physical injuries should not have been considered by the
    jury when evaluating the gravity of the harm Wilson suffered from Edison’s
    interference with her property, we must reverse the judgment and remand the
    matter to the trial court for a retrial on the nuisance claim.
    a. Jury Instructions on Retrial
    Because the nuisance claim must be retried, we must address an issue
    regarding the jury instruction for that claim. As noted, the jury was instructed that
    to find in favor of Wilson, it had to find that “the seriousness of the harm [suffered
    by Wilson] outweighed the public benefit of Southern California Edison
    Company’s conduct.” No instructions were given as to what factors the jury
    should consider in making this determination. We conclude that additional
    instructions are required because without any guidance on the factors to consider,
    the jury cannot properly assess the seriousness of the harm or the public benefit.
    In Covalt, the Supreme Court discussed the unique nature of a private
    nuisance cause of action. The Court compared nuisance to trespass, and noted that
    unlike trespass, a nuisance claim requires proof “that the invasion of the plaintiff’s
    interest in the use and enjoyment of the land was substantial, i.e., that it caused the
    plaintiff to suffer ‘substantial actual damage’” and that “‘[t]he interference with the
    protected interest [was] unreasonable’ [citation], i.e., it must be ‘of such a nature,
    duration or amount as to constitute unreasonable interference with the use and
    enjoyment of the land.’” 
    (Covalt, supra
    , 13 Cal.4th at p. 938.) The Court
    observed that “[t]his requirement flows from the law’s recognition that ‘Life in
    47
    organized society and especially in populous communities involves an unavoidable
    clash of individual interests. Practically all human activities unless carried on in a
    wilderness interfere to some extent with others or involve some risk of
    interference, and these interferences range from mere trifling annoyances to serious
    harms. It is an obvious truth that each individual in a community must put up with
    a certain amount of annoyance, inconvenience and interference and must take a
    certain amount of risk in order that all may get on together. The very existence of
    organized society depends upon the principle of “give and take, live and let live,”
    and therefore the law of torts does not attempt to impose liability or shift the loss in
    every case in which one person’s conduct has some detrimental effect on another.
    Liability for damages is imposed in those cases in which the harm or risk to one is
    greater than he ought to be required to bear under the circumstances, at least
    without compensation.’ (Rest.2d Torts, § 822, com. g., p. 112.)” 
    (Covalt, supra
    ,
    13 Cal.4th at pp. 937-938.)
    The Court explained that “[t]he primary test for determining whether the
    invasion is unreasonable is whether the gravity of the harm outweighs the social
    utility of the defendant’s conduct, taking a number of factors into account.”
    
    (Covalt, supra
    , 13 Cal.4th at p. 938, italics added.) The Court did not discuss those
    factors – because it found in that case that the nuisance claim was under the
    exclusive jurisdiction of the PUC – but instead cited to the Restatement Second of
    Torts, sections 826 through 831.
    Section 826 of the Restatement provides that an invasion is unreasonable if
    “(a) the gravity of the harm outweighs the utility of the actor’s conduct, or [¶]
    (b) the harm caused by the conduct is serious and the financial burden of
    compensating for this and similar harm to others would not make the continuation
    of the conduct not feasible.” (Rest.2d Torts, § 826.)
    48
    Section 827 of the Restatement lists the factors to be considered in
    determining the gravity of the harm from an intentional invasion of another’s
    interest in the use and enjoyment of land: “(a) The extent of the harm involved;
    [¶] (b) the character of the harm involved; [¶] (c) the social value that the law
    attaches to the type of use or enjoyment invaded; [¶] (d) the suitability of the
    particular use or enjoyment invaded to the character of the locality; and [¶] (e) the
    burden on the person harmed of avoiding the harm.” (Rest.2d Torts, § 827.)
    The factors to be considered in determining the social utility of conduct that
    causes an intentional invasion of another’s interest in the use and enjoyment of
    property are found in section 828 of the Restatement: “(a) the social value that the
    law attaches to the primary purpose of the conduct; [¶] (b) the suitability of the
    conduct to the character of the locality; and [¶] (c) the impracticability of
    preventing or avoiding the invasion.” (Rest.2d Torts, § 828.)
    Restatement sections 829 through 831 provide alternate tests to determine
    when an intentional invasion is unreasonable: when the harm caused by the
    invasion is “significant” and the actor’s conduct is “for the sole purpose of causing
    harm to the other” or “contrary to common standards of decency” (Rest.2d Torts,
    § 829); when “the harm resulting from the invasion is severe and greater than the
    other should be required to bear without compensation” (Rest.2d Torts, § 829A);
    when “the harm is significant and it would be practicable for the actor to avoid the
    harm in whole or in part without undue hardship” (Rest.2d Torts, § 830); or when
    the harm is “significant” and “the particular use or enjoyment interfered with is
    well suited to the character of the locality” and “the actor’s conduct is unsuited to
    the character of that locality” (Rest.2d Torts, § 831).
    The CACI instruction given to the jury in this case (CACI No. 2021) did not
    address any of these factors or alternate tests. The absence of any instruction on
    these factors or tests not only left the jury without any guidance as to the proper
    49
    focus of their deliberations,34 it also rendered CACI No. 2021 an incorrect
    statement of the law because it allowed the jury to find liability for nuisance even
    if the jury did not find that the harm to Wilson was substantial. The instruction
    merely stated, as the fifth element that Wilson must prove, “that Simona Wilson
    was harmed.” (See CACI No. 2021, element 6 [“6. That [name of plaintiff] was
    harmed”].) Moreover, the fourth element set forth in the instruction seemed to
    suggest that the harm need not be substantial, because it stated that Edison’s
    conduct needed only be enough to “reasonably” annoy or disturb an ordinary
    person. (CACI No. 2021, element 5 [“5. That an ordinary person would be
    reasonably annoyed or disturbed by [name of defendant]’s conduct”].)
    Had the jury been instructed on the proper factors to consider when
    weighing the gravity of the harm against the social utility of Edison’s conduct and
    found Edison liable, the statement of these elements would be sufficient because in
    finding in favor of Wilson the jury necessarily would have concluded that the harm
    was substantial. Without such instruction, it is not. Therefore, on retrial the jury
    must be given an additional instruction to supplement CACI No. 2021. The
    34
    In fact, Wilson’s attorney may have misled the jury about what it should consider
    when determining whether the seriousness of the harm outweighed the public benefit of
    Edison’s conduct. Addressing this element during closing argument, counsel stated:
    “[T]he final element here is that the seriousness of the harm outweighs the public benefit.
    That, I think, is an easy one because no one is claiming there’s a public benefit to putting
    unacceptable levels of voltage on fixtures.” Counsel misidentified the “public benefit” to
    be considered. The question is not whether the interference itself is a “public benefit.”
    Rather, the question is whether the conduct that causes the interference is a “public
    benefit.” (See Rest.2d Torts, § 828, subd. (a) [to determine the social utility of conduct
    that causes the invasion, one must consider “the social value that the law attaches to the
    primary purpose of the conduct”], italics added.)
    50
    additional instruction, which for clarity should immediately follow CACI No.
    2021, is as follows:35
    In determining whether the seriousness of the harm Wilson suffered
    outweighed the public benefit of Edison’s conduct you should consider the
    following factors.
    To determine the seriousness of the harm Wilson suffered, you should
    weigh:
    a. The extent of the harm, meaning how much the condition Edison caused
    (that is, stray voltage) interfered with Wilson’s use or enjoyment of her property,
    and how long that interference lasted.
    b. The character of the harm, that is, whether the harm involved a loss from
    the destruction or impairment of physical things she was using, or personal
    discomfort or annoyance.
    c. The value society places on the type of use or enjoyment invaded; in this
    case the property was used as a residence. The greater the social value of the
    particular type of use or enjoyment of land that is invaded, the greater the gravity
    of harm from the invasion.
    d. The suitability of the type of use or enjoyment invaded to the character of
    the locality. The character of a locality is based upon the primary kind of activity
    at that location, such as residential, industrial, or other activity.
    e. The extent of the burden (such as expense and inconvenience) on Wilson
    to avoid the harm.
    35
    By providing this instruction, we simply seek to give guidance to the trial court in
    this case. We suggest that the CACI committee consider our concerns regarding CACI
    No. 2021 and determine if additional instructions should be drafted for use generally in
    nuisance cases.
    51
    To determine the social utility of Edison’s conduct, you should weigh:
    a. The value society places on the primary purpose of the conduct that
    caused the interference. The primary purpose of the conduct means Edison’s main
    objective for engaging in the conduct. How much social value a particular purpose
    has depends upon how much its achievement generally advances or protects the
    public good.
    b. The suitability of the conduct that caused the interference to the character
    of the locality. The suitability of the conduct depends upon its compatibility to the
    primary activities carried on in the locality.
    c. The practicability or impracticality of preventing or avoiding the
    invasion.
    D.    Punitive Damages
    Edison contends the punitive damages award must be reversed because there
    is no substantial evidence that an Edison managing agent authorized or ratified any
    alleged malicious, oppressive, or fraudulent conduct. We agree.
    “In a civil case not arising from the breach of a contractual obligation, the
    jury may award punitive damages ‘where it is proven by clear and convincing
    evidence that the defendant has been guilty of oppression, fraud, or malice.’ (Civ.
    Code, § 3294, subd. (a).) ‘Malice’ is defined as intentional injury or ‘despicable
    conduct which is carried on by the defendant with a willful and conscious
    disregard of the rights or safety of others.’ (Id., § 3294, subd. (c)(1).) ‘Oppression’
    is defined as ‘despicable conduct that subjects a person to cruel and unjust hardship
    in conscious disregard of that person’s rights.’ (Id., § 3294, subd. (c)(2).)” (Roby
    v. McKesson Corp. (2009) 
    47 Cal. 4th 686
    , 712.) The term “despicable” is not
    defined in the statute, but the Supreme Court has observed that it is applicable to
    52
    “circumstances that are ‘base,’ ‘vile,’ or ‘contemptible.’” (College Hospital, Inc.
    v. Superior Court (1994) 
    8 Cal. 4th 704
    , 725.)
    When the defendant is a corporation, “[a]n award of punitive damages
    against a corporation . . . must rest on the malice of the corporation’s employees.
    [¶] But the law does not impute every employee’s malice to the corporation.”
    (Cruz v. HomeBase (2000) 
    83 Cal. App. 4th 160
    , 167.) Instead, the oppression,
    fraud, or malice must be perpetrated, authorized, or knowingly ratified by an
    officer, director, or managing agent of the corporation. (Civ. Code, § 3294, subd.
    (b).) “‘[M]anaging agent’ . . . include[s] only those corporate employees who
    exercise substantial independent authority and judgment in their corporate
    decisionmaking so that their decisions ultimately determine corporate policy.”
    (White v. Ultramar, Inc. (1999) 
    21 Cal. 4th 563
    , 566-567.)
    In this case, Edison notes that Wilson’s assertion that an officer or managing
    agent of Edison authorized or knowingly ratified alleged despicable conduct is
    based upon the testimony of two witnesses: William Perry, an employee of the gas
    company, who testified that discussions between Edison and the gas company
    regarding mitigation of stray voltage on neighborhood gas meters included vice
    presidents of Edison; and Tina Drebushenko, an Edison employee who sent emails
    regarding reports of shocks at the property in 1997 to several Edison employees,
    including at least one manager who “should have some impact with [Edison]
    policy.” Wilson does not dispute that this was the only evidence showing
    knowledge on the part of Edison officers or managing agents.
    But as Edison observes, even if this testimony establishes that managing
    agents ratified or authorized something, the conduct they ratified was far from
    despicable. While these managing agents no doubt were aware that stray voltage
    was present on Wilson’s property (although Wilson did not own the property at the
    time of Drebushenko’s email), they were made aware of that in the context of
    53
    Edison attempting to mitigate it to ensure the level of voltage did not present any
    danger to the occupants of the property. This certainly does not constitute
    oppression, fraud, or malice. Therefore, the punitive damages award must be
    reversed. Because Wilson failed to present sufficient evidence to support an award
    of punitive damages, she is not entitled to seek punitive damages on retrial of her
    nuisance claim.
    DISPOSITION
    The judgment is reversed. On remand, the trial court is directed to
    enter judgment in favor of Edison on Wilson’s IIED and negligence claims, and
    hold a retrial of her nuisance claim. On retrial, the trial court must instruct the jury
    on the factors it should consider in determining whether the gravity of the harm
    Wilson suffered outweighed the public benefit of Edison’s conduct that caused the
    interference. Wilson is not entitled to seek punitive damages on retrial. The
    parties shall bear their own costs on appeal.
