    Case Summary
    [1]   Indianapolis Power & Light Company (“IPL”) petitioned the Indiana Utility
    Regulatory Commission (“the Commission”) for approval of an increase to its
    base rates for provision of electricity, which had been in effect since 1995. The
    Commission granted requests for intervention by Citizens Action Coalition,
    Indiana Community Action Association, Indiana Coalition for Human
    Services, Indiana Association for Community Economic Development,
    National Association of Social Workers Indiana Chapter, and Indiana State
    Conference of the National Association for the Advancement of Colored
    People (collectively, “Joint Intervenors”), and by IPL Industrial Group (“IPL
    Group”), The Kroger Company, and the City of Indianapolis.1 The proposed
    rate increase was approved by the Commission. After the denial of various
    petitions for reconsideration, Joint Intervenors appealed. We affirm. 2

    The Indiana Office of the Utility Consumer Counselor (“the OUCC”) is a statutory party to rate
    proceedings, as a consumer representative.
    2
    By a separate order, we grant Joint Intervenors’ motion to dismiss the Commission as a party to this appeal.
    Because the Commission acted as a fact-finding administrative tribunal and no statute or administrative
    provision expressly makes the Commission a party on appeal, it is not a proper party on appeal from its own
    decision. See e.g., Citizens Action Coalition of Indiana, Inc. v. So. Indiana Gas & Electricity Co., 
    2017 WL 587261
    ,

    Commission of Indiana], as here, its action in making findings and issuing an order deemed detrimental by
    one of the parties is similar to that of a court which makes a decision determining a controversy between
    adverse parties. A court is never a party to an appeal from its decision.”)
    Court of Appeals of Indiana | Opinion 93A02-1604-EX-804 | April 5, 2017                                Page 3 of 23
    Issue
    [2]   Joint Intervenors articulate four issues claiming that the order lacks adequate
    support, particularly challenging (1) the lack of findings specifically addressing
    the impact of a particular rate component, a declining block rate (“DBR”),
    upon energy conservation, (2) the lack of findings specifically addressing the
    effect of DBR on elderly and African-American customers, (3) the rejection of a
    proposal for 25% low-income customer subsidies, and (4) the rejection of
    mandatory reporting by IPL of interruption-in-service data. We consolidate
    and restate the issues to conform to our standard of review, that is, a
    Commission order will stand unless no substantial evidence supports it or it is
    contrary to law,3 and address the following issue: Whether the Commission’s
    rate approval order is not conclusive and binding due to a lack of specific
    findings on factual determinations material to its ultimate conclusions.
    Facts and Procedural History
    [3]   On December 29, 2014, IPL, an investor-owned public utility providing
    electrical service to approximately 470,000 ratepayers in and around
    Indianapolis, filed a base-rate-increase petition with the Commission. IPL
    proposed that the fixed customer charge, a flat fee for access to the electrical
    grid, would rise from $6.70 per month to $11.25 per month for customers using
    3
    Northern Ind. Public Serv. Co. v. U.S. Steel Corp., 
    907 N.E.2d 1012
    , 1015 (Ind. 2009).
    Court of Appeals of Indiana | Opinion 93A02-1604-EX-804 | April 5, 2017                      Page 4 of 23
    0 to 325 kilowatt hours and from $11.00 to $17.00 for customers using over 325
    kilowatt hours. The energy charge, a volumetric charge equal to the approved
    rate multiplied by the number of kilowatt hours consumed, would rise from
    $0.093346 to $0.093935 for the first 500 kilowatt hours and from $0.070346 to
    $0.073000 thereafter.4 Because customers consuming greater than 500 kilowatt
    hours incrementally pay less than the lower-usage customers for the energy
    charge portion of the bill, the rate scheme incorporates a DBR.
    [4]   The Commission consolidated the base rate case with a facilities investigation
    case and conducted nine days of evidentiary hearings. At the hearing, Joint
    Intervenors opposed the increase to the monthly fixed customer charge and
    presented testimony opposing the DBR on grounds that charging less at higher
    usage rates penalizes low volume customers and does not promote energy
    conservation. Also, Joint Intervenors urged adoption of a 25% subsidy for
    certain customers, to be funded by an incremental usage increase on other
    customers, and requested an order that IPL provide Joint Intervenors with data
    on service interruption events pertaining to low-income customers.
    [5]   IPL presented testimony acknowledging that, in the absence of demand meters
    and/or time-of-use meters, the most cost-justified rate design would be a
    straight fixed-rate/variable rate. In this design, fixed rates are entirely

    The inclusion of fuel and Demand Side Management (“DSM”) charges would cause a rise to $0.097416
    from $0.096827 and to $0.076481 from $0.073827, for the first 500 kilowatt hours and over 500 kilowatt
    hours, respectively. There was also a third block reduced rate for residential users of electric hot water
    heaters and space heaters who consumed over 1,000 kilowatt hours per month.
    Court of Appeals of Indiana | Opinion 93A02-1604-EX-804 | April 5, 2017                          Page 5 of 23
    recovered from the fixed charges and variable costs are entirely recovered from
    variable charges. However, IPL proposed gradualism as opposed to a total
    conversion to straight fixed-rate/variable rate methodology within one rate
    proceeding. Additionally, there was testimony that economically efficient
    pricing is achieved when a price is set equal to the marginal cost of production,
    and that flat energy charges (eliminating DBR) do not mirror costs in that it
    does not cost twice as much to produce twice as much electricity.
    [6]   Economist Glenn Watkins (“Watkins”), who testified for the OUCC after
    conducting an evaluation of IPL’s proposal, opined that “the current level of
    customer charges is appropriate.” (Tr. at 8208.) According to Watkins, the
    proposed increases to the fixed monthly customer charge “violate the regulatory
    principle of gradualism, violate the economic theory of efficient competitive
    pricing, and are contrary to effective conservation efforts.” (Tr. at 8200.) With
    regard to DBR, Watkins recommended: “[DBR rates] be eliminated gradually
    to a flat rate structure. However, this restructuring of residential and small
    commercial rates should be done in a gradual and systematic manner to avoid
    rate shock to large volume heating customers.” (Tr. at 8212.) He
    recommended a phase out in three rate cases, with equal increments.
    [7]   On March 16, 2016, the Commission issued its final order approving IPL’s
    proposed rate increase and rejecting the proposals for a low-income customer
    subsidy and service interruption reporting requirements. We do not re-produce
    the eighty-three-page opinion here, but recite portions relevant to Joint
    Intervenor’s positions:

    Comprehensive Low Income Bill Payment Assistance Program
    Evidence. Joint Intervenors witness Howat recommended
    implementation of a low income rate that would be paid for by
    all classes of customers through a volumetric charge and that the
    low income rate be available to all residential customers at or
    below 150% of the poverty level. His recommendation was a
    25% discounted rate. He also recommended a plan to implement
    a low-income arrearage write-down program by retiring pre-
    program arrearages through 12 timely payments of discounted
    bills. He conducted and submitted analysis for the Commission’s
    consideration of the account activity among Low Income Home
    Energy Assistance program (“LIHEAP”) customers – number of
    overdue accounts, disconnect notices, and disconnection for
    nonpayment. Joint Intervenor witness Fraser presented
    demographic data concerning income levels and poverty rates in
    Indiana and Marion County.
    Industrial Group witness Phillips contended that recovery of
    social program costs is divorced from any cost causation
    principles and distorts electric price signals. He testified that the
    proposed program is best addressed by the Indiana state
    legislature.
    In rebuttal, IPL witness Gaske testified that the Joint Intervenors’
    proposal raises significant policy issues for the Commission to
    address and that perhaps the manner and amount of low income
    assistance would be more appropriately addressed in a generic
    proceeding involving all regulated electric utilities or by the
    legislature.
    Discussion and Findings. We recognize the importance of the
    issues raised by Joint Intervenors, but find that there are
    numerous implementation and policy related concerns. The
    timing of the introduction of the proposal in this proceeding has
    Court of Appeals of Indiana | Opinion 93A02-1604-EX-804 | April 5, 2017         Page 7 of 23
    not provided an opportunity for sufficient consideration of the
    complexities involved. As pointed out by Mr. Phillips, the
    application of costs that could be considered beyond the cost of
    electric service distorts electric service price signals. A well-
    designed proposal would include a thorough understanding of
    how it would create or alleviate any costs of providing electric
    service. Further, access to key demographic and billing
    information the affected utility or utilities collect and hold is
    integral to evaluating any specific program design. Absent this
    information, we decline to adopt Mr. Howat’s recommendations
    in this proceeding.
    Joint Intervenors also have proposed that IPL be ordered to
    collect and report trend data on arrearages, disconnections, and
    related data points. While a properly designed program of the
    type suggested by Joint Intervenors would benefit from this
    information, and we encourage IPL to consider working with the
    Joint Intervenors and other interested stakeholders in further
    identifying beneficial information, we decline to order such
    collection and reporting solely on the basis of the evidence before
    us. We believe that any such effort is best pursued by the utility
    and interested stakeholders outside the regulatory constraints of a
    specific Commission directive.
    Rate Design.
    Evidence. Dr. Gaske explained that the rate design objective was
    guided by two goals: (1) the residential increase would remain
    less than 10%; and (2) no rate schedule would receive a rate
    decrease. The rate design proposed for residential and
    commercial rate classes by Dr. Gaske included moving
    additional fixed costs into the customer charge component of the
    bill. The result is a customer charge that increases by a greater
    percentage than the overall rate increase. He explained that the
    proposed level does not include all the fixed costs. In conducting
    the revenue proof, Dr. Gaske gave effect to the movement of
    Court of Appeals of Indiana | Opinion 93A02-1604-EX-804 | April 5, 2017   Page 8 of 23
    customers who are eligible to migrate to a different rate schedule
    that would be more financially advantageous to them. He
    testified that after this case is concluded, IPL will notify those
    customers who would achieve lower bills by moving to a
    different rate schedule. The effect of this migration will result in
    the new rate schedule producing $1.187 million less in revenue,
    which was added to the overall rate increase requested.
    OUCC witness Watkins objected to the increase to the residential
    customer charge. He testified that it violates gradualism, violates
    efficient competitive pricing, and discourages conservation. Mr.
    Watkins also opposed Dr. Gaske’s proposed migration
    adjustment.5 The migration adjustment was based upon an
    analysis of customers and a determination that a number of the
    customers would be financially benefitted if they migrated to an
    alternative rate schedule. Mr. Watkins claimed that one cannot
    assume that a customer will choose to move to a more
    economical rate. He noted that savings for most would be less
    than 10%.
    ...
    Joint Intervenor witness Howat also objected to the increase to
    the customer charge and continuation of declining block rates.
    He testified that rate structures such as these have a
    disproportionate impact on low income, elderly, and African
    American customers, and that on average, low income customers
    use less electricity than the average or than their higher income
    counterparts.
    Industrial Group witness Phillips objected to the proposed
    increase in the demand charge for the HL class. . . . Kroger

    Migration refers to movement between an SS (energy only) rate and SL (demand plus energy) rate.
    Court of Appeals of Indiana | Opinion 93A02-1604-EX-804 | April 5, 2017                         Page 9 of 23
    witness Higgins testified that he supports IPL’s proposed rate
    design, including the increases to the demand charge for the HL
    and SL classes. City witness Sommer disagreed with IPL’s rate
    migration objective that no class receive a rate decrease. . . .
    In rebuttal, Dr. Gaske responded to Mr. Watkins’ testimony
    concerning economic efficiency and testified that economic
    theory supports the concept that economic efficiency is promoted
    by recovering fixed costs through a fixed charge and only
    variable costs in a variable charge. He noted that IPL is not
    proposing a straight fixed variable (“SFV”) rate design in this
    case. He testified that while a SFV rate design would provide
    better price signals, IPL’s proposed rates would continue to
    recover 75% of residential fixed costs through the energy charge
    and 81% of small commercial fixed costs. He agreed that
    declining block rates are not as cost-justified as a SFV rate design,
    but are more cost-justified than a flat energy charge in that the
    declining block rate structure represents a reasonable
    compromise approach in which successively larger rate blocks
    move closer to the marginal cost of energy. He further responded
    to Mr. Watkins’ contention that the increase in the customer
    charge violates a principle of gradualism by noting that
    gradualism looks at the total bill, which is the sum of both the
    customer and energy charges. The proposed increase in
    customer charge would significantly reduce the percentage
    increase in energy charge that would otherwise be required and
    thereby offset the increase in the customer charge which is the
    focus of Mr. Watkins’ argument.
    With respect to the Joint Intervenors’ position, Dr. Gaske cited
    details concerning the percentage of residential customers who
    are enrolled in the LIHEAP program and those who are not,
    showing that, in general, the energy usage characteristics among
    the residential class for LIHEAP customers are very similar to
    the no-assistance customers. As a result, proposals for lower
    customer charges and/or flat energy charges are likely to increase
    Court of Appeals of Indiana | Opinion 93A02-1604-EX-804 | April 5, 2017   Page 10 of 23
    the monthly bills of the significant portion of low income energy
    assistance customers who have above-average energy use, and
    reduce the bills of the significant portion of customers who are
    not low income but have below-average energy use.
    ...
    Discussion and Findings.
    Increase in Residential Customer Charge and Continuation of Declining
    Block Rates. There were only two arguments presented in
    opposition to IPL’s customer charge proposal: Mr. Watkins’
    contention that all costs are variable in the long run and therefore
    SFV rates represent inefficient pricing, and Mr. Howat’s
    testimony that Petitioner’s rate design produces a
    disproportionate impact on low income customers.
    As to the first argument, we note that IPL has not proposed SFV
    rates. While the proposed increases in the customer charge from
    $6.70 to $11.25 (for less than 325 kWh/month) and $11.00 to
    $17.00 (for greater than 325 kWh/month) move toward a more
    fixed and variable rate design consistent with traditional cost
    causation principals, it is demonstrably short of SFV rates. There
    is no evidence that the customer charge as designed even reaches
    the level of full distribution system fixed cost recovery. Cost
    recovery design alignment with cost causation principles sends
    efficient price signals to customers, allowing customers to make
    informed decisions regarding their consumption of the service
    being provided. The Commission investigated the rate design
    issue with regard to natural gas service in Cause No. 43180, and
    the general premise appears to be reasonably applicable to
    electric utilities in the context of distribution-related costs.
    Notwithstanding, gradualism in any movement is a reasonable
    consideration, and we find that the increase in customer charge is
    consistent with the Commission’s preference for gradual changes
    Court of Appeals of Indiana | Opinion 93A02-1604-EX-804 | April 5, 2017    Page 11 of 23
    in rate structures. We note that IPL’s proposed customer charge
    represents the first increase in the customer charge since base
    rates were last changed in 1995.
    With respect to the second argument, Dr. Gaske’s analysis
    demonstrated that approximately 8-10% of the customers within
    each residential class receive energy assistance, yet the median
    usage and the 90th percentile usage for energy assistance
    customers compared to no-assistance customers is similar. While
    switching to an inclining block rate structure may benefit low
    income/low energy users, it would harm a substantial number of
    low income/high energy users. Many low-income customers use
    more than the residential average amount.
    Ultimately, we find that Petitioner’s proposed rate design to
    increase the customer charge and maintain declining block rates
    should be approved. We further find that this structure does not
    violate principles of gradualism, because gradualism is best
    considered in the context of the entire customer bill and not
    discrete charges within the bill.

    [8]   The Commission subsequently issued a Nunc Pro Tunc Order unrelated to this
    appeal. On April 5, 2015, Joint Intervenors, IPL Group, and The Kroger
    Company filed petitions seeking reconsideration of various aspects of the Order.
    On June 1, 2016, the Commission denied those petitions. Joint Intervenors and
    the OUCC filed notices of appeal. Subsequently, the OUCC filed a motion to
    Court of Appeals of Indiana | Opinion 93A02-1604-EX-804 | April 5, 2017   Page 12 of 23
    dismiss its notice of appeal.6 The appeal initiated by Joint Intervenors
    proceeded.
    Standard of Review
    [9]    The Commission was created by the Indiana General Assembly to act
    “primarily as a fact-finding body with the technical expertise to administer the
    regulatory scheme designed by the legislature.” Northern Ind. Public Serv. v. U.S.
    Steel, 
    907 N.E.2d 1012

    responsibility “to insure that public utilities provide constant, reliable, and
    efficient service to the citizens of Indiana.” 
    Id. The Commission
    can exercise
    only that power which has been conferred upon it by statute. 
    Id. [10] This
    statutory scheme reflects a basic legislative policy that questions of rate-

    [11]   Indiana Code Section 8-1-3-1 provides for judicial review of the Commission’s
    decisions in language almost identical to provisions for judicial review of other
    administrative agency actions:
    Any person, firm, association, corporation, limited liability
    company, city, town or public utility adversely affected by any
    final decision, ruling, or order of the commission may, within
    thirty (30) days from the date of entry of such decision, ruling, or
    order, appeal to the court of appeals of Indiana for errors of law
    under the same terms and conditions as govern appeals in
    ordinary civil actions, except as otherwise provided in this
    chapter and with the right in the losing party or parties in the
    court of appeals to apply to the supreme court for a petition to
    transfer the cause to said supreme court as in other cases. An
    assignment of errors that the decision, ruling, or order of the
    commission is contrary to law shall be sufficient to present both
    the sufficiency of the facts found to sustain the decision, ruling,
    or order, and the sufficiency of the evidence to sustain the finding
    of facts upon which it was rendered.
    [12]   Our review is two-tiered:
    On the first level, it requires a review of whether there is
    substantial evidence in light of the whole record to support the
    Commission’s findings of basic fact. Citizens Action Coalition of
    Ind., Inc. v. N. Ind. Pub. Serv. Co., 
    485 N.E.2d 610
    , 612 (Ind.
    1985). Such determinations of basic fact are reviewed under a
    substantial evidence standard, meaning the order will stand
    unless no substantial evidence supports it. McClain [v. Review Bd.
    Of Ind. Dept. of Workforce Dev., 
    693 N.E.2d 1314
    , 1317-18 (Ind.

    Declining Block Rates – Disparate Impact
    [13]   At the hearing, Joint Intervenors opposed a rate scheme inclusive of DBR, that
    is, the volumetric charge decrease from $0.093935 to $0.070346 after the first
    Court of Appeals of Indiana | Opinion 93A02-1604-EX-804 | April 5, 2017   Page 15 of 23
    500 kilowatt hours of usage. Joint Intervenors argued that this is a disincentive
    for conservation and disproportionately harms elderly, African-American, and
    low income customers.
    [14]   In response to an inquiry about the “general public policy” applicable to DBR,
    Watkins testified:
    In 1978, Congress passed the Public Utility Regulatory Policies
    Act (“PURPA”). Among other things, PURPA established
    various conservation initiatives and mandates for electric utilities.
    Included in this Act is a clear policy to eliminate declining-block
    energy rates unless supported by costs. Specifically, PURPA
    states:
    ‘Declining Block Rates. The energy component of a rate, or the
    amount attributable to the energy component in a rate, charged
    by any electric utility for providing electric service during any
    period to any class of electric consumers may not decrease as
    kilowatt-hour consumption by such class increases during such
    period except to the extent that such utility demonstrates that the
    costs to such utility or providing electric service to such class,
    which costs are attributable to such energy component, decrease
    as such consumption increases during such period.’
    Since this time, most states and commissions have abandoned
    the once prevalent declining-block rate structures in favor of flat,
    or inverted, block rates. The general policy supporting the
    elimination of such declining-block rates is that this type of rate
    structure is clearly at odds with energy conservation due to the
    fact that the incremental price of electricity decreases as
    consumption increases, thereby creating somewhat of an
    incentive to use more and more electricity. Indeed, declining-
    block electricity rates became popular in the 1960s and early
    1970s and were used as a promotional tool to encourage the
    Court of Appeals of Indiana | Opinion 93A02-1604-EX-804 | April 5, 2017    Page 16 of 23
    increased usage of relatively cheap electricity during a time in
    which there were significant natural gas shortages through the
    Country.
    (Tr. at 8210.)
    [15]   On appeal, Joint Intervenors claim that the Commission’s order “is deficient
    because the Commission failed to make basic findings of fact or a conclusion of
    law as to whether DBR has a deleterious effect on energy conservation and
    energy efficiency programs sponsored by the utility.” Appellant’s Br. at 25.
    According to Joint Intervenors, the Commission “ignored the substantial
    evidence presented by both CAC and the OUCC, demonstrating that ‘this type
    of structure is clearly at odds with energy conservation due to the fact that the
    incremental price of electricity decreases as consumption increases, thereby
    creating somewhat of an incentive to use more and more electricity.”’
    Appellant’s Br. at 27 (quoting App. at 190-91). They ask that we remand the
    order “for the Commission to determine whether the DBR rate structure is
    deleterious to energy conservation and utility-sponsored energy efficiency
    programs.” Appellant’s Br. at 30.
    [16]   We do not find this particular relief warranted. Joint Intervenors did not bring
    a declaratory judgment action; rather, they intervened in a rate case. Rate-
    making is a legislative as opposed to a judicial function, and our Indiana
    Legislature has seen fit to establish a commission for the express purpose of
    hearing evidence and balancing and weighing the many complicated factors
    which must be taken into consideration in setting utility rates. State ex rel.

    261 Ind. 583
    , 586-87, 
    307 N.E.2d 870
    , 872 (1974). The enabling act does not authorize the Commission to issue
    declaratory rulings. See U.S. Steel Corp. v. No. Ind. Public Serv. Co., Inc., 
    482 N.E.2d 501
    , 506 (Ind. Ct. App. 1985), trans. denied.
    [17]   In their insistence upon particular language, Joint Intervenors attempt to shift
    the focus from the reasonableness of the order approving the rate change as a
    whole to one component. As the Commission acknowledged, an ideal rate
    scheme would closely align recovery of fixed costs with fixed rates and variable
    costs with variable rates based upon usage. However, there was ample
    testimony to support the Commission’s conclusions that, in light of the fact that
    IPL’s base rates had not been increased since 1995, an abrupt rate structure
    overhaul ignoring the principles of gradualism would be undesirable.
    Ultimately, the Commission incorporated the principle of “gradualism,” (App.
    at 96), and approved a rate structure that was not a straight fixed rate/variable
    rate structure.
    [18]   Joint Intervenors make a cursory claim that “approval of DBR despite its
    deleterious effect on energy conservation is contrary to federal law, state rule,
    and existing precedent.” Appellant’s Br. at 27. They note that the National
    Energy Policy Act of 1992 encourages state regulators of utilities to consider
    setting rates to promote energy efficient investments. They also note that, in a
    separate utility case, the Commission found the utility’s proposal to gradually
    eliminate DBR rates to be reasonable. See In re Verified Petition of So. Ind. Gas &
    Electric Co., Cause No. 43839, 2011 Ind. PUC LEXIS 115, 215 (I.U.R.C. Apr.
    Court of Appeals of Indiana | Opinion 93A02-1604-EX-804 | April 5, 2017     Page 18 of 23
    27, 2011). The parties do not dispute the proposition that public policy, federal
    and State, favors and encourages conservation.
    [19]   Nonetheless, encouragement is not a mandate. Joint Intervenors direct us to no
    statutory requirement that each individual component of a rate scheme reflect
    the most environmentally conservative approach or that abandonment of older
    methodology be immediate and total. At bottom, Joint Intervenors suggest a
    reweighing of evidence, with conservation – based upon their interpretation of
    customer usage signals – being paramount. They do not demonstrate the
    unreasonableness of the rate increase as a whole.
    [20]   In a similar vein, Joint Intervenors argue that the Commission “did not make
    any specific findings of fact or make an ultimate finding of reasonableness as to
    the material issue raised regarding whether the continuance of the DBR
    structure disproportionately harms elderly consumers and African American
    consumers.” Appellant’s Br. at 31. Joint Intervenors observe that the
    Commission has a duty to see that the rates are fair and reasonable, both to the
    consumers and to the utility; claim that “no party rebutted the [Joint
    Intervenor] evidence on this issue”; and ask for remand “to determine whether
    the DBR rate structure disproportionately harms elderly and African American
    ratepayers.” Appellant’s Br. at 31-32.
    Court of Appeals of Indiana | Opinion 93A02-1604-EX-804 | April 5, 2017   Page 19 of 23
    [21]   Joint Intervenors presented testimony to the effect that lower income customers
    use less electricity on average.7 IPL presented testimony that their customers
    participating in energy assistance programs show similar characteristics of
    usage compared to customers not receiving assistance, looking at median usage
    and 90th percentile usage. Even assuming that DBR has a disproportionate
    negative impact upon certain groups of customers, the Commission is required
    by statute to approve rates that are fair and reasonable inclusive of the entire
    customer base. There is no statutory requirement that the impact upon
    particular sub-groups be separately addressed. Joint Intervenors have not
    demonstrated that the Commission failed to conform to statutory standards.
    [22]   “On matters within its jurisdiction, the Commission enjoys wide discretion.
    The Commission’s findings and decision will not be lightly overridden just
    because we might reach a contrary opinion on the same evidence.” NIPSCO

    , 5-6 (Ind. Ct. App. 2015)
    (internal citation omitted.) As explained by Watkins, “it is generally accepted
    that to the extent possible, joint costs should be allocated to customer classes
    based on the concept of cost causation,” but “although there are certain
    principles used by all cost of service analysts, there are often significant
    disagreements on the specific factors that drive individual costs.” (Tr. at 8147-
    48.)

    The data base was not limited to IPL or Indiana customers.

    [23]   Challengers have the burden of showing there is insufficient evidence in the
    record to support the findings of the Commission; they cannot merely cite to
    other evidence of record which would support a determination more favorable
    to their position. Bethlehem Steel Corp. v. N. Ind. Pub. Serv. Co., 
    397 N.E.2d 623
    ,
    628 (Ind. Ct. App. 1979). Here, the findings contain enough detail such that we
    can determine whether the order is reasonable, within the wide discretion of the
    Commission.
    Subsidy Program and Reporting Requirements
    [24]   Joint Intervenors complain that the Commission did not make sufficient
    findings to support its rejection of Joint Intervenors’ requests for a 25% subsidy
    to low-income customers and for mandatory reporting of service interruption
    events so as to assist the Intervenors in supporting future arguments with such
    data. As a threshold matter, we observe that Joint Intervenors argue that the
    Commission must make findings with respect to disparate socioeconomic
    impact of rate increases, but have not shown that the Commission had a
    statutory duty to make any findings at all in this regard. Joint Intervenors were
    permitted to intervene in a rate-making case, but this did not change the nature
    of the proceeding from rate-making to a broad socio-economic inquiry akin to
    that which might be undertaken by the General Assembly.
    [25]   The Commission is to approve rates that are just and reasonable. Within the
    statutory language, there is no requirement that the unique position of
    particular groups of consumers be separately considered. Joint Intervenors are
    Court of Appeals of Indiana | Opinion 93A02-1604-EX-804 | April 5, 2017   Page 21 of 23
    not entitled to specific findings on propositions they have injected unless it is a
    matter material to the rate decision. Citizens Action 
    Coalition, 485 N.E.2d at 612
    .
    In other words, the Commission does not have to justify to Joint Intervenors
    why it rejected a subsidy outside general rate-making principles and a reporting
    obligation. Joint Intervenors had to justify to the Commission why a direct
    subsidy and reporting requirement should be adopted within a rate case. They
    failed to do so.
    [26]   That said, the Commission has shown some inclination to hear socio-economic
    evidence in a rate case. It did not simply ignore the Joint Intervenors’
    argument. Rather, after hearing limited evidence, the Commission
    acknowledged the need for broader-based evidence and observed that the
    legislature is better suited to determinations of if and when one citizen is
    burdened to benefit another. Undeniably, lower income persons at times
    struggle to obtain basic necessities. But the struggle for necessities of life is
    broader; what of those who have above-poverty incomes but increased
    expenses, a larger family size, or significant medical needs? The drawing of
    lines in the face of myriad considerations and competing concerns is
    traditionally a function performed by our General Assembly. See Citizens Action
    Coalition v. Public Serv. Co., 
    450 N.E.2d 98
    , 103 (Ind. Ct. App. 1983) (affirming
    the Commission decision declining to require Indiana electric utilities to offer a
    “life-line” rate structure providing a below-cost rate for essential residential
    customer needs and observing, “any decision to implement an assistance

    program not based on sound regulatory principles must be made by the
    legislature.”)8
    [27]   Again, Joint Intervenors have not shown that the Commission failed to
    conform to statutory standards or failed to make requisite findings.
    Conclusion
    [28]   Joint Intervenors have not shown that the Commission decision approving a
    rate design that includes DBR is unsupported by requisite findings. Joint
    Intervenors have not shown that the rate approval order is non-binding due to a
    lack of more extensive factual findings on matters introduced by Joint
    Intervenors which were not directly material to components of the approved
    rate design.
    [29]   Affirmed.

    In the order affirmed on appeal, the Commission found that a rate “targeted” to specific income or
    demographic groups of residential customers was prohibited by law and a general lifeline rate structure was
    not an effective and equitable means of providing assistance to low-income residential customers. Citizens
