    LUNDBERG STRATTON, J.
    {¶ 1} This appeal stems from a major proceeding in which the Ohio
    Public Utilities Commission authorized new generation rates for the American
    Electric Power operating companies (“AEP”) Columbus Southern Power
    Company and Ohio Power Company. The appellants, the Office of the Ohio
    Consumers’ Counsel (“OCC”) and Industrial Energy Users-Ohio (“IEU”), raise
    13 propositions of law. We hold that the commission committed reversible error
    on three grounds, affirm on all other issues, and remand the order to the
    commission for further proceedings.
    I. Factual Background
    {¶ 2} In 2008, the General Assembly enacted Senate Bill 221, 2008
    Am.Sub.S.B. No. 221 (“S.B. 221”), which substantially revised the regulation of
    SUPREME COURT OF OHIO
    electric service in Ohio. Before S.B. 221, there was Senate Bill 3. Adopted in
    1999, Senate Bill 3, 148 Ohio Laws, Part IV, 7962, was designed “to facilitate
    and encourage development of competition in the retail electric market.” AK

    95 Ohio St. 3d 81
    , 
    765 N.E.2d 862
    .
    Competition, however, “fail[ed] * * * to develop according to expectations.”

    114 Ohio St. 3d 340

    , ¶ 3.
    {¶ 3} This failure followed a nationwide trend. Soon after several states
    passed deregulatory laws, “two tumultuous events—the crisis of electric power in
    California and the collapse of the world’s largest electric trading corporation,
    Enron”—“cast something of a cloud over the deregulation movement, which had
    been almost the signature cause of the 1980s and 1990s.” Cudahy, Whither
    Deregulation: A Look at the Portents (2001), 58 N.Y.U. Ann.Surv.Am.Law 155,
    155. Beyond these particular crises, “the cost of generating power increased
    significantly, due primarily to increases in the costs of the underlying fuel
    sources.” Van Nostrand, Constitutional Limitations on the Ability of States to
    Rehabilitate Their Failed Electric Utility Restructuring Plans (2008), 31 Seattle
    U.L. Rev. 593, 593–594. Several states experimenting with deregulation found,
    as did Ohio, that “the anticipated competition did not develop.” 
    Id. at 593.
           {¶ 4} Faced with a lack of competition, rising electricity prices, and
    unpalatable market-based rates, the commission and utilities responded with
    various rate plans not expressly contemplated by statute. In reviewing these
    plans, we recognized the possibility that additional legislative action might be
    required. In Ohio Consumers’ Counsel, 
    114 Ohio St. 3d 340
    , 2007-Ohio-4276,
    
    872 N.E.2d 269
    , ¶ 41, we observed, “[A]s we continue to see the rate-stabilization
    plans appealed from the commission, we presume that the commission is sharing
    its evaluations and reports on the effectiveness of competition with the legislature,
    * * * so that it can continue to evaluate the need for further legislative action.”
    2
    January Term, 2011
    {¶ 5} “[F]urther legislative action” arrived with S.B. 221.          The bill
    addressed several areas of concern with electric markets.         Pertinent here, it
    established new standards to govern generation rates. See R.C. 4928.141 through
    4928.144.    Broadly speaking, the new regulatory regime requires electric-
    distribution utilities to provide consumers with “a standard service offer of all
    competitive retail electric services necessary to maintain essential electric service
    to consumers, including a firm supply of electric generation service.”          R.C.
    4928.141(A). The utility may provide the offer in one of two ways: through a
    “market rate offer” under R.C. 4928.142 or through an “electric security plan”
    under R.C. 4928.143. The market-rate offer, as the name implies, sets rates using
    a competitive-bidding process to harness market forces.
    {¶ 6} AEP applied for the second option, an electric security plan
    (“ESP”). It filed its application on July 31, 2008, and multiple parties intervened.
    A hearing was held from November to December 2008, briefing was completed
    over the holidays, and on March 18, 2009, the commission issued a 77-page
    opinion and order modifying and approving the plan. Two rounds of rehearing
    applications followed, resolved by entries on July 23 and November 4. OCC and
    IEU appealed. AEP has intervened in support of the commission.
    II. Discussion
    {¶ 7} The appellants have raised 13 propositions of law, which we have
    reduced to ten issues. We begin with the three issues in which the appellants have
    demonstrated error.
    A. OCC Propositions of Law 1, 2, and 3: The commission violated
    the law by granting a retroactive rate increase, but OCC is not
    entitled to a monetary refund
    {¶ 8} In its first three propositions of law, OCC argues that the
    commission unlawfully granted AEP a $63 million retroactive rate increase, in
    violation of R.C. 4928.141(A), as well as the rule established in Keco Industries,
    3
    SUPREME COURT OF OHIO
    Inc. v. Cincinnati & Suburban Bell Tel. Co. (1957), 
    166 Ohio St. 254
    , 2 O.O.2d
    85, 
    141 N.E.2d 465
    .       We agree with OCC on the merits: the commission
    unlawfully granted a retroactive rate increase. For reasons discussed, however,
    OCC has not established that it is entitled to its requested remedy of a refund.
    1. The commission unlawfully granted AEP a retroactive rate increase
    {¶ 9} AEP had sought a rate increase effective January 2009, but the
    commission did not issue an order until mid-March. Thus, from January through
    March, AEP collected less revenue than it would have if the application had been
    approved before January 1.        In response to this delay in rate relief, the
    commission set AEP’s rates at a level “intended to permit the companies to
    recover 12 months of revenue over a 9-month period.” The additional increase
    totaled $63 million.
    {¶ 10} This was retroactive ratemaking. Although the commission did not
    authorize AEP to rebill customers for usage from January through March, it
    reached the same financial result by setting rates from April through December
    2009 at a level sufficient to recover lost revenues from January through March.
    In AEP’s words, “the Commission’s decision * * * yield[s] a similar financial
    impact as would have occurred if a decision had been issued by December 28,
    2008 * * *.” By approving rates that recouped losses due to past regulatory delay,
    the commission violated this court’s case law on retroactive ratemaking, as well
    as provisions of S.B. 221.
    {¶ 11} A rate increase making up for revenues lost due to regulatory delay
    is precisely the action that we found contrary to law in Keco. “[A] utility may not
    charge increased rates during proceedings before the commission seeking same [,]
    and losses sustained thereby”—that is, while the case is pending—“may not be
    recouped.” 
    Keco, 166 Ohio St. at 259
    , 2 O.O.2d 85, 
    141 N.E.2d 465
    . Likewise,
    in Lucas Cty. Commrs. v. Pub. Util. Comm. (1997), 
    80 Ohio St. 3d 344
    , 348, 
    686 N.E.2d 501
    , we ruled that “utility ratemaking * * * is prospective only” and that
    4
    January Term, 2011
    R.C. Title 49 “prohibit[s] utilities from charging increased rates during the
    pendency of commission proceedings and appeals.” 
    Id. These cases
    make plain
    that present rates may not make up for dollars lost “during the pendency of
    commission proceedings.” 
    Id. That is
    exactly what occurred here.
    {¶ 12} The appellees respond by arguing that Keco’s rule does not apply
    in proceedings under the new statutes of S.B. 221. We need not decide whether
    Keco continues to apply, as the ruling also violates a provision of S.B. 221 itself,
    under R.C. 4928.141(A). That section specifically prescribes the applicable rates
    if a new standard service offer has not been approved by January 1, 2009:
    preexisting rates “shall continue * * * until a standard service offer is first
    authorized under section * * * 4928.143.” (Emphasis added.) R.C. 4928.141(A);
    see R.C. 4928.01(A)(33) (“ ‘Rate plan’ means the standard service offer in effect
    on the effective date of the amendment of this section by S.B. 221 of the 127th
    general assembly, July 31, 2008”).
    {¶ 13} This section rules out retroactive rate increases. The requirement
    to continue existing rates is mandatory. Although the statute does not expressly
    prohibit a retroactive rate increase, the express remedy (to “continue” existing
    rates until new rates are approved) rules out nonexpress remedies (such as
    tracking and restoring the difference between old and new rates if approval is
    delayed). See, e.g., Myers v. Toledo, 
    110 Ohio St. 3d 218
    , 2006-Ohio-4353, 
    852 N.E.2d 1176
    , ¶ 24 (“the express inclusion of one thing implies the exclusion of
    the other”). This statutory and case law concerning retroactive ratemaking spans
    nearly 50 years. Cf. Clark v. Scarpelli (2001), 
    91 Ohio St. 3d 271
    , 278, 
    744 N.E.2d 719
    (“It is presumed that the General Assembly is fully aware of any prior
    judicial interpretation of an existing statute when enacting an amendment”).
    {¶ 14} Thus, under either the case-law or under R.C. 4928.141(A), the
    commission violated the law when it granted AEP additional rates to make up for
    the regulatory delay.
    5
    SUPREME COURT OF OHIO
    2. OCC did not avail itself of the remedy provided by law
    {¶ 15} This conclusion leads to the more difficult question: What remedy
    is available for OCC? The unlawful rate increase lasted until the end of 2009 and
    has been fully recovered, so reversing the retroactive increase will not reduce
    ongoing rates. The rule against retroactive rates, however, also prohibits refunds.
    {¶ 16} OCC argues that the commission should have made the entire rate
    increase subject to refund but cites no authority under which the commission
    could have done so. As OCC recognizes, under Keco, we have consistently held
    that the law does not allow refunds in appeals from commission orders. As we
    stated only two years ago, “any refund order would be contrary to our precedent
    declining to engage in retroactive ratemaking.” Ohio Consumers’ Counsel v. Pub.
    Util. Comm., 
    121 Ohio St. 3d 362
    , 2009-Ohio-604, 
    904 N.E.2d 853
    , ¶ 21; see also,
    e.g., Green Cove Resort I Owners’ Assn. v. Pub. Util. Comm., 
    103 Ohio St. 3d 125
    , 2004-Ohio-4774, 
    814 N.E.2d 829
    , ¶ 27 (“Neither the commission nor this
    court can order a refund of previously approved rates, however, based on the
    doctrine set forth in Keco * * *”); Keco, 
    166 Ohio St. 254
    , 2 O.O.2d 85, 
    141 N.E.2d 465
    , paragraph two of the syllabus (R.C. Title 49 “affords no right of
    action for restitution of the increase in charges collected during the pendency of
    the appeal”). These precedents remain good law and still apply to these facts,
    thus prohibiting the granting of a refund.
    {¶ 17} We recognize that the no-refund rule transforms OCC’s win on the
    merits into a somewhat hollow victory.        Any apparent unfairness, however,
    remains a policy decision mandated by the larger legislative scheme. As Keco
    and other cases have noted, the statutes protect against unlawfully high rates by
    allowing stays.     R.C. 4903.16 authorizes the court to stay execution of
    commission orders.      This section makes “clear that the General Assembly
    intended that a public utility shall collect the rates set by the commission’s order,
    giving, however, to any person who feels aggrieved by such order a right to
    6
    January Term, 2011
    secure a stay of the collection of the new rates after posting a bond.” 
    Keco, 166 Ohio St. at 257
    , 2 O.O.2d 85, 
    141 N.E.2d 465
    . The stay remedy “completely
    abrogated” the form of refund (a restitution order) sought in that case. 
    Id. at 259.
           {¶ 18} The difficulty for OCC is that to obtain such a stay, it must
    “execute an undertaking * * * conditioned for the prompt payment by the
    appellant of all damages caused by the delay in the enforcement of the order.”
    R.C. 4903.16; see also Office of Consumers’ Counsel v. Pub. Util. Comm. (1991),
    
    61 Ohio St. 3d 396
    , 403–404, 
    575 N.E.2d 157
    (the bond requirement applies to
    OCC under “R.C. 4903.16, and this court’s interpretation thereof”). OCC acted
    with diligence and speed to secure a financial remedy in this case: it filed an
    action in prohibition, a quick—and premature—appeal, an action for a writ of
    procedendo, and a motion to suspend the order in this case. Critically, however,
    OCC did not seek to post a bond—in fact, it affirmatively sought to avoid doing
    so.
    {¶ 19} OCC concedes that it failed to post bond, but asserts that it is “not
    financially capable of posting any bond other than a nominal amount,” a
    circumstance that makes “a stay * * * truly an illusory remedy at best unless the
    Court relieves OCC from filing a bond.” To the degree that the bond requirement
    poses a barrier, however, it is one that must be cured by the General Assembly.
    Unquestionably, it is the prerogative of the General Assembly to establish the
    bounds and rules of public-utility regulation. See, e.g., Akron v. Pub. Util. Comm.
    (1948), 
    149 Ohio St. 347
    , 359, 
    78 N.E.2d 890
    (“the legislative branch of the state
    government may confer upon” the commission “very broad [powers]” for the
    “supervision, regulation and, in a large measure, control of the operation of public
    utilities”). And our “revisory jurisdiction” over agency proceedings is limited to
    that “conferred by law.” Section 2(d), Article IV, Ohio Constitution.
    {¶ 20} The legislature has seen fit to attach a significant requirement to
    the court’s stay power: the posting of a bond sufficient to protect the utility
    7
    SUPREME COURT OF OHIO
    against damage. R.C. 4903.16. If the General Assembly so desired, it could
    remove or loosen this condition on the stay power. It has not done so, despite
    decades of cases refusing to grant a refund. At bottom, then, the statutory scheme
    creates OCC’s problem. We understand the difficulty a public agency such as
    OCC faces in dealing with the bond requirement. Nevertheless, the statute is
    clear, and it clearly applies. Whether it is wise to apply the bond requirement to
    OCC is a matter for the General Assembly to consider, not this court.
    {¶ 21} For these reasons, we hold that the commission’s decision to
    authorize a retroactive rate increase was unlawful, but we deny OCC’s refund
    request.
    B. IEU Proposition of Law 3; OCC 5: In approving a provider-of-last-resort
    charge, the commission relied on a justification lacking any record support.
    {¶ 22} The commission approved the recovery of roughly $500 million in
    provider-of-last-resort (“POLR”) charges over the three years of the plan. OCC
    and IEU attack the charge on several grounds, including that the commission
    lacked record support.
    {¶ 23} Under Ohio law, customers may purchase generation service from
    a competitive supplier. If such a supplier fails to provide service, “the supplier’s
    customers * * * default[] to the utility’s standard service offer * * * until the
    customer chooses an alternative supplier.” R.C. 4928.14. This obligation to stand
    ready to accept returning customers makes the utility the “provider of last resort,”
    or “POLR.” See, e.g., Constellation NewEnergy, Inc. v. Pub. Util. Comm., 
    104 Ohio St. 3d 530
    , 2004-Ohio-6767, 
    820 N.E.2d 885
    , ¶ 39, fn. 5 (“POLR costs are
    those costs incurred by [the utility] for risks associated with its legal obligation as
    the default provider, or electricity provider, of last resort, for customers who shop
    and then return to [the utility] for generation service”). In other reviews of POLR
    charges, we have admonished the commission to “carefully consider what costs it
    8
    January Term, 2011
    is attributing” to “POLR obligations.” Ohio Consumers’ Counsel v. Pub. Util.
    Comm., 
    114 Ohio St. 3d 340
    , 2007-Ohio-4276, 
    872 N.E.2d 269
    , ¶ 26.
    {¶ 24} Below, the commission approved a POLR charge totaling over
    $500 million over the term of the ESP. It described the charge as cost-based.
    “[T]he POLR rider will be based on the cost to the Companies to be the POLR
    and carry the risks associated therewith * * *.” (Emphasis added.) Likewise, it
    stated that it was allowing recovery of “estimated POLR costs.” (Emphasis
    added.) Again on rehearing, the commission stated that it had “determined that
    the Companies should be compensated for the cost of carrying the risk associated
    with being the POLR provider.” (Emphasis added.) This characterization of the
    POLR charge as cost-based lacks any record support; therefore, we reverse the
    portion of the order approving the POLR charge.
    {¶ 25} We have carefully reviewed the record, and we can find no
    evidence suggesting that AEP’s POLR charge is related to any costs it will incur.
    AEP derived its charge using a mathematical formula created to price exchange-
    traded options. The company analogized an option to buy and sell securities to
    the statutory right to shop for power, changed some variables, and applied the
    formula. This formula, called “the Black-Scholes model” after two of its creators,
    is the only evidence AEP presented in support of its POLR charge.
    {¶ 26} Contrary to the order, this formula simply does not reveal “the cost
    to the Companies to be the POLR and carry the risks associated therewith.” The
    record shows that the model does not even purport to estimate costs, but instead
    tries to quantify “the value of the optionality [to shop for power] that is provided
    to customers under Senate Bill 221.” Value to customers (what the model shows)
    and cost to AEP (the purported basis of the order) are simply not the same thing.
    AEP’s own witness made this clear—“[t]rying to recover the costs of the
    Companies’ POLR obligation retrospectively would fail, because it ignores the
    very nature of the POLR obligation. The value of the customers’ right to switch
    9
    SUPREME COURT OF OHIO
    under S.B. 221 comes from the option customers are given to switch suppliers,
    while still having the safety net of the ESP rate * * *.” (Emphases added.)
    {¶ 27} Even assuming that AEP accurately priced the option, we fail to
    see how the amount a customer would be willing to pay for the right to shop
    necessarily establishes AEP’s costs to bear the attendant risks. The order does not
    explain the relationship between the two.       And witnesses for other parties
    confirmed that the POLR charge was not based on cost. A witness for OCC
    testified that AEP has “not identified any specific costs they are incurring related
    to the POLR obligation.” Another witness agreed that AEP does “not appear to
    have an actual out of pocket expense.” Along similar lines, a member of the
    commission’s staff stated that “a POLR charge, if one is considered appropriate,
    would be significantly below what AEP is requesting.”
    {¶ 28} Other facts in the record further call into question the accuracy of
    AEP’s POLR theory.       The record showed that AEP has had “virtually no”
    shopping in the last eight years, including no residential shoppers.            No
    countervailing evidence predicted an uptick in shopping. No witness testified that
    more switching could be expected in the future, and AEP performed no “actual
    customer surveys” or “studies apart from the Black-Scholes model” to determine
    whether shopping was likely to increase. On the contrary, the commission’s own
    economist testified that “there are many reasons to think that substantial migration
    will not quickly occur, even if the market price falls below the SSO [standard
    service offer] price.” Even AEP’s witness testified that “[d]esire to switch, in
    [his] view, will be when there’s an economic advantage,” but that “today,” there
    is “no economic advantage.” Accordingly, AEP did not even “have a plan to
    purchase” options to hedge its own POLR risk. At the very least, all this evidence
    raises doubts about the proposition that AEP would justifiably expend $500
    million to bear the POLR risk.
    10
    January Term, 2011
    {¶ 29} In short, the manifest weight of the evidence contradicts the
    commission’s conclusion that the POLR charge is based on cost. In contrast with
    our recent admonition that the commission must “carefully consider what costs it
    is attributing” to “POLR obligations,” Ohio Consumers’ Counsel, 
    114 Ohio St. 3d 340
    , 2007-Ohio-4276, 
    872 N.E.2d 269
    , ¶ 26, no evidence supports the
    commission’s characterization of this charge as based on cost. Ruling on an issue
    without record support is an abuse of discretion and reversible error. See, e.g.,
    Indus. Energy Users-Ohio v. Pub. Util. Comm., 
    117 Ohio St. 3d 486
    , 2008-Ohio-
    990, 
    885 N.E.2d 195
    , ¶ 30. Therefore, we reverse the provisions of the order
    authorizing the POLR charge.
    {¶ 30} On remand, the commission may revisit this issue. To be clear, we
    express no opinion on whether a formula-based POLR charge is per se
    unreasonable or unlawful, and the commission may consider on remand whether a
    non-cost-based POLR charge is reasonable and lawful.           Alternatively, the
    commission may consider whether it is appropriate to allow AEP to present
    evidence of its actual POLR costs. However the commission chooses to proceed,
    it should explain its rationale, respond to contrary positions, and support its
    decision with appropriate evidence.
    C. OCC Proposition of Law 6: The commission erred in determining
    that ESPs may include items not specifically authorized by statute
    {¶ 31} In its sixth proposition of law, OCC argues that R.C.
    4928.143(B)(2) does not permit AEP to recover certain carrying costs associated
    with environmental investments. That section states, “The [electric security] plan
    may provide for or include, without limitation, any of the following,” and then
    lists nine categories of cost recovery. OCC argues that this section permits plans
    to include only listed items; the commission and AEP argue that (B)(2) permits
    unlisted items. We agree with OCC.
    11
    SUPREME COURT OF OHIO
    {¶ 32} By its terms, R.C. 4928.143(B)(2) allows plans to include only
    “any of the following” provisions.       It does not allow plans to include “any
    provision.” So if a given provision does not fit within one of the categories listed
    “following” (B)(2), it is not authorized by statute.
    {¶ 33} The commission believes that the phrase “without limitation”
    allows unlisted items, asserting that the nine categories are “illustrative, * * * not
    exhaustive.” But this phrase does not allow unlisted items. Rather, it allows
    unlimited inclusion of listed items. The list limits the type of categories a plan
    may include, while the phrase “without limitation” allows as many or as much of
    the listed categories as the commission finds reasonable—subject to any other
    applicable limits, which we do not consider here.
    {¶ 34} The plain language of the statute controls, and this interpretation
    leads to a reasonable result. However, the appellees’ interpretation would remove
    any substantive limit to what an electric security plan may contain, a result we do
    not believe the General Assembly intended.
    {¶ 35} For the foregoing reasons, we reverse the commission’s legal
    determination that R.C. 4928.143(B)(2) permits ESPs to include unlisted items.
    On remand, the commission may determine whether any of the listed categories
    of (B)(2) authorize recovery of environmental carrying charges.
    D. IEU Proposition of Law 1: The commission did not lose jurisdiction
    over the case when the 150-day approval deadline expired
    {¶ 36} In its first proposition of law, IEU argues that the commission “lost
    jurisdiction over AEP-Ohio’s July 31, 2008 ESP Application when it failed to
    authorize an ESP within the 150-day time frame required by R.C. 4928.143.” We
    disagree.
    {¶ 37} “ ‘As a general rule, a statute which provides a time for the
    performance of an official duty will be construed as directory so far as time for
    performance is concerned, especially where the statute fixes the time simply for
    12
    January Term, 2011
    convenience or orderly procedure.’ ” In re Davis (1999), 
    84 Ohio St. 3d 520
    , 522,
    
    705 N.E.2d 1219
    , quoting State ex rel. Jones v. Farrar (1946), 
    146 Ohio St. 467
    ,
    471–472, 
    32 Ohio Op. 542
    , 
    66 N.E.2d 531
    . “This is so ‘unless the nature of the act to
    be performed or the phraseology of the statute or of other statutes relating to the
    same subject-matter is such that the designation of time must be considered a
    limitation upon the power of the officer.’ ” 
    Id., quoting State
    ex rel. Smith v.
    Barnell (1924), 
    109 Ohio St. 246
    , 255, 
    142 N.E. 611
    .
    {¶ 38} Under this principle, deadlines concerned with “the prompt
    conduct of the public business” should be considered “directory,” not mandatory.
    Jones at 472. The use of the word “shall” to institute the deadline does not
    change this.    See Davis at 522 (“even with ‘shall’ as the operative verb, a
    statutory time provision may be directory”). And a deadline provision that does
    not “mandate any particular result if the * * * decision is untimely” further
    supports a directory interpretation. State ex rel. Larkins v. Wilkinson (1997), 
    79 Ohio St. 3d 477
    , 479, 
    683 N.E.2d 1139
    ; see also, e.g., Davis at 522 (a deadline
    was directory where it did “not include any expression of intent to restrict the
    jurisdiction of the court for untimeliness”).
    {¶ 39} Applying these standards, we hold that R.C. 4928.143(C)(1)’s 150-
    day deadline is directory and that the commission retained jurisdiction over the
    case when the deadline expired.
    {¶ 40} R.C. 4928.143(C)(1) provides: “The commission shall issue an
    order under this division for an initial application under this section not later than
    one hundred fifty days after the application’s filing date and, for any subsequent
    application by the utility under this section, not later than two hundred seventy-
    five days after the application’s filing date.”
    {¶ 41} Considering the act as a whole, we find it plain that the General
    Assembly enacted the 150-day deadline to ensure prompt review of initial ESP
    applications. To begin with, that is how we generally interpret such provisions, In
    13
    SUPREME COURT OF OHIO
    re 
    Davis, 84 Ohio St. 3d at 522
    , 
    705 N.E.2d 1219
    , and numerous provisions of
    S.B. 221 confirm that the general rule applies here. For example, the introductory
    section of S.B. 221 requires electric distribution utilities to provide a standard
    service offer by a specific date, January 1, 2009. R.C. 4928.141(A). Given that
    the law took effect July 31, 2008, the utilities and the commission had not quite
    six months to have new rates put into effect. Six months is a comparatively short
    amount of time for a major rate proceeding; the commission is given almost twice
    as much time (275 days) to resolve a distribution-rate proceeding, see R.C.
    4909.42, and later ESP proceedings. See R.C. 4928.143(C)(1). Moreover, the
    statute expressly permits utilities to file their applications “prior to the effective
    date of any rules the commission may adopt for the purpose of this section.” R.C.
    4928.143(A).
    {¶ 42} All this suggests that the General Assembly meant to hasten the
    filing and review of initial ESPs, not set a jurisdictional bar. IEU points to no
    factors that suggest the opposite. For example, R.C. 4928.143 does not impose
    any consequence for exceeding the 150-day deadline.            It does not mandate
    dismissal and refiling. Notably, this consequence is required in other scenarios,
    but not for expiration of the 150-day deadline. See R.C. 4928.143(C)(2)(a) and
    (b).
    {¶ 43} R.C. 4928.143(C)(1)’s deadline effectuates “the proper, orderly,
    and prompt” resolution of initial ESP applications. 
    Jones, 146 Ohio St. at 472
    , 
    32 Ohio Op. 542
    , 
    66 N.E.2d 531
    . The deadline is not jurisdictional, and we reject IEU’s
    first proposition of law.
    E. IEU Proposition of Law 2: IEU has not shown error in
    AEP’s acceptance and appeal of its ESP
    {¶ 44} In its second proposition of law, IEU argues that the commission
    should have “prohibit[ed] AEP-Ohio from accepting the benefits of the higher
    14
    January Term, 2011
    rates approved in the ESP while simultaneously preserving the right to withdraw
    and terminate the approved ESP.” This argument lacks merit.
    {¶ 45} Under R.C. 4928.143(C)(1), the commission must do one of three
    things when an ESP is filed: it must “approve,” “modify and approve,” or
    “disapprove” the application.      “If the commission modifies and approves an
    application,” the utility “may withdraw the application, thereby terminating it, and
    may file a new standard service offer.” R.C. 4928.143(C)(2)(a).
    {¶ 46} In this case, the commission modified and approved the ESP. AEP
    filed tariffs instituting the new rates but stated in its cover letter, “The Companies
    do not waive * * * their right under § 4928.143(C)(2), Ohio Rev. Code, regarding
    withdrawal of their Application.” According to IEU, AEP “has never formally
    accepted its approved ESP, is still taking the benefits of the ESP, and has filed an
    appeal of its ESP to this Court.” IEU contends that a utility “cannot accept the
    benefits of the rates approved in an ESP while simultaneously preserving the right
    to withdraw and terminate the ESP.”
    {¶ 47} IEU has not met its burden of showing error. The law permits
    utilities to withdraw modified ESPs, but does not require it, R.C.
    4928.143(C)(2)(a), and IEU cites no authority requiring “formal acceptance” of
    an ESP. The fact that AEP has neither withdrawn nor formally accepted its
    application does not show error.
    {¶ 48} We will not weigh in on whether AEP could collect ESP rates for
    some period of time and then withdraw the plan. AEP has not done so, and we do
    not address hypothetical questions. See State ex rel. Elyria Foundry Co. v. Indus.

    {¶ 49} IEU has failed to demonstrate legal error, and we reject its second
    proposition of law.

    SUPREME COURT OF OHIO
    F. OCC Proposition of Law 4: The commission adequately
    explained why it was not following prior decisions in allowing
    AEP to keep the proceeds of “off-system sales”
    {¶ 50} In its fourth proposition of law, OCC argues that the order departed
    from precedent without sufficient explanation. The commission allowed AEP to
    keep all proceeds from “off-system sales,” meaning unregulated sales to other
    resellers and not to retail customers, rather than requiring AEP to give the net
    profits of those sales as a rate credit to consumers. OCC asserts that in past cases,
    the commission required utilities to share with customers the revenue from such
    sales. According to OCC, the commission has departed from this precedent
    without sufficient explanation.
    {¶ 51} At the outset, we note that OCC does not argue that the underlying
    decision was substantively unlawful and unreasonable. In fact, OCC concedes
    that the law “does not require profits from off-system sales to be included in the
    ESP rates”that is, shared with customers. Its argument is procedural and
    limited to whether the commission “failed to explain why it was departing from
    precedent.”
    {¶ 52} It is true that we have instructed the commission to “respect its
    own precedents in its decisions to assure the predictability which is essential in all
    areas of the law, including administrative law.” Cleveland Elec. Illum. Co. v.
    Pub. Util. Comm. (1975), 
    42 Ohio St. 2d 403
    , 431, 71 O.O.2d 393, 
    330 N.E.2d 1
    ,
    superseded on other grounds by statute as recognized in Babbit v. Pub. Util.
    Comm. (1979), 
    59 Ohio St. 2d 81
    , 89, 13 O.O.3d 67, 
    391 N.E.2d 1376
    . This does
    not mean that the commission may never revisit a particular decision, only that if
    it does change course, it must explain why. See, e.g., Util. Serv. Partners, Inc. v.
    Pub. Util. Comm., 
    124 Ohio St. 3d 284
    , 2009-Ohio-6764, 
    921 N.E.2d 1038
    , ¶ 18;
    Office of Consumers’ Counsel v. Pub. Util. Comm. (1985), 
    16 Ohio St. 3d 21
    , 21–
    22, 16 OBR 371, 
    475 N.E.2d 786
    (“A few simple sentences in the commission’s
    16
    January Term, 2011
    order in this case would have sufficed” to explain why a previous order had been
    overruled). The new course also must be substantively reasonable and lawful, but
    OCC, as noted, has not placed that at issue here.
    {¶ 53} Here, the commission explained why it did not follow the cases
    cited by OCC as precedent. None of them arose under the applicable body of law,
    S.B. 221. And the commission further concluded that the applicable law now in
    place does not even require OCC’s requested treatment, a point that OCC
    concedes.
    {¶ 54} The commission adequately explained why it did not follow the
    cases cited by OCC.      As this is the only basis on which OCC attacks the
    commission’s treatment of off-system sales, we reject its fourth proposition of
    law.
    G. IEU Proposition of Law 4: IEU fails to show error concerning
    the approval of charges related to a pair of generation stations
    {¶ 55} In its fourth proposition of law, IEU argued that the commission
    should not have allowed recovery of charges associated with a pair of generation
    stations. According to IEU, the commission “cannot use traditional cost-based
    ratemaking selectively to increase rates where it believes particular categories of
    competitive generation costs are not currently reflected in rates.” (Emphases sic.)
    {¶ 56} “ ‘[A] party who contends’ ” that rates and charges are
    unreasonable “ ‘has the burden on appeal to the Supreme Court under Section
    4903.13, Revised Code, of showing that they are unjust, unreasonable or
    unlawful.’ ” AT & T Communications of Ohio, Inc. v. Pub. Util. Comm. (1990),
    
    51 Ohio St. 3d 150
    , 154, 
    555 N.E.2d 288
    , quoting Columbus v. Pub. Util. Comm.
    (1959), 
    170 Ohio St. 105
    , 10 O.O.2d 4, 
    163 N.E.2d 167
    , paragraph two of the
    syllabus. IEU fails to carry its burden here. At no point does appellant even
    purport to cite a specific legal authority that prohibits cost-based rates in an ESP.
    Several times, it asserts that S.B. 221 prohibits the commission’s action. S.B.
    17
    SUPREME COURT OF OHIO
    221, however, is over 50 pages long, so this general citation does not provide
    enough guidance.
    {¶ 57} Conclusory assertions that the commission cannot do something
    fall well short of demonstrating reversible error. IEU’s argument in its fourth
    proposition is inadequately developed, and we reject it on that basis.
    H. IEU Proposition of Law 5: IEU fails to show error in the approval of
    AEP’s vegetation-management and smart-grid programs.
    {¶ 58} In its fifth proposition of law, IEU challenges the commission’s
    approval of parts of AEP’s proposed enhanced-vegetation-management1 and
    smart-grid programs. Neither challenge succeeds.
    {¶ 59} Regarding the vegetation-management program, IEU faults the
    commission for inconsistency—it approved this distribution charge but not others
    that had been requested. AEP had proposed four types of charges related to
    distribution service. The commission decided not to address three of the four,
    finding it better to examine those charges in “a distribution rate case where all
    components of distribution rates are subject to review.” Nevertheless, it allowed
    recovery of an “enhanced vegetation initiative,” based on its findings that “a
    specific need exists” for the initiative and that the charges were necessary to
    expand the current program.
    {¶ 60} IEU asserts that this decision to approve some but not all
    distribution charges was unexplained. That is not true. The commission did
    explain why it considered one distribution program but not the others—“AEP-
    Ohio has demonstrated in the record of this proceeding that it faces increased
    costs for vegetation management and that a specific need exists for the
    implementation of the enhanced vegetation initiative * * *.” IEU does not explain
    1. “Vegetation management” refers to trimming trees, clearing rights-of-way, and other activities
    necessary to keep wires clear. See generally Corrigan v. Illum. Co., 
    122 Ohio St. 3d 265
    , 2009-
    Ohio-2524, 
    910 N.E.2d 1009
    , ¶ 15.
    18
    January Term, 2011
    in any further detail what else the commission should have explained, so this
    portion of its argument is settled.
    {¶ 61} In the other part of its fifth proposition, IEU argues that the
    commission approved AEP’s “gridSMART” proposal “without any showing that
    [it] satisfied the cost-effectiveness requirements of R.C. 4928.02(D).”          The
    provision cited by IEU states that “it is the policy of the state” to “[e]ncourage
    innovation and market access for cost-effective supply- and demand-side retail
    electric service including, but not limited to, demand-side management, time-
    differentiated pricing, and implementation of advanced metering infrastructure.”
    IEU has not demonstrated legal error.
    {¶ 62} To begin with, and contrary to IEU’s assumption, R.C. 4928.02(D)
    does not impose strict “cost-effectiveness requirements” on any given program—
    indeed, by its terms, it does not require anything. It simply expresses state policy.
    As we have held, such policy statements are “guideline[s] for the commission to
    weigh” in evaluating utility proposals to further state policy goals, and it has been
    “left * * * to the commission to determine how best to carry [them] out.” Ohio
    Consumers’ Counsel v. Pub. Util. Comm., 
    125 Ohio St. 3d 57
    , 2010-Ohio-134,
    
    926 N.E.2d 261
    , ¶ 39–40.          The commission plainly weighed this policy
    consideration in reviewing the programs. That alone is grounds to reject IEU’s
    argument.
    {¶ 63} In any event, the commission acted in step with the policy of R.C.
    4928.02(D).     By approving the initiation of the smart-grid program, the
    commission “[e]ncourage[d] innovation and market access” for “supply- and
    demand-side retail electric services,” specifically including “implementation of
    advanced metering infrastructure.” R.C. 4928.02(D). As to cost-effectiveness,
    the commission imposed several requirements to ensure prudent spending:
    “separate accounting for gridSMART, an opportunity to approve and update the
    plan each year, assurance that expenditures are made before cost recovery occurs,
    19
    SUPREME COURT OF OHIO
    and an opportunity to audit expenditures prior to recovery.”       Moreover, the
    commission cut in half the proposed cost-recovery and required AEP to seek
    federal stimulus funding.      These provisions reduced costs and imposed
    mechanisms to protect consumers from unwarranted spending.
    {¶ 64} For the foregoing reasons, we reject IEU’s fifth proposition of law.
    I. IEU Proposition of Law 6: IEU has not demonstrated error in the
    commission’s setting of AEP’s fuel-cost baseline
    {¶ 65} ESPs may provide for “[a]utomatic recovery” of “the cost of fuel
    used to generate the electricity supplied under the offer,” “provided the cost is
    prudently incurred.” R.C. 4928.143(B)(2)(a). In its sixth proposition of law, IEU
    asserts that the commission violated the prudently-incurred-cost requirement
    when it used certain estimated fuel-cost figures in establishing AEP’s base rate.
    This argument lacks merit.
    {¶ 66} We note up front that IEU does not attack the use of an estimate
    per se, but merely the commission’s choice of what estimate to use. IEU, AEP,
    and the commission’s staff each proposed fuel-cost estimates; the commission
    adopted staff’s. And we further note, because the record confirms, that no matter
    which estimate was used, only actual costs were to be recovered.
    {¶ 67} IEU argues that the commission’s choice of estimate violates R.C.
    4928.143(B)(2)(a). That section authorizes “[a]utomatic recovery” of “the cost of
    fuel” “provided the cost is prudently incurred.” The commission complied with
    this section. As noted above, only actual costs will be recovered, and as the
    commission stated in its order, they will be subject to prudence review (“the FAC
    [fuel adjustment clause] mechanism includes a quarterly reconciliation to actual
    FAC costs incurred,” and the staff recommendation was adopted for “an annual
    prudency and accounting review” of the FAC).
    {¶ 68} Moreover, IEU points to no legal authority that speaks to how the
    commission should determine or estimate fuel-cost baselines.        Any lack of
    20
    January Term, 2011
    statutory guidance on that point should be read as a grant of discretion. See, e.g.,
    Payphone Assn. v. Pub. Util. Comm., 
    109 Ohio St. 3d 453
    , 2006-Ohio-2988, 
    849 N.E.2d 4
    , ¶ 25 (“When a statute does not prescribe a particular formula, the
    PUCO is vested with broad discretion”). IEU simply has not shown an abuse of
    discretion. It asserts that the commission’s estimate has the effect of “pushing too
    much money associated with the FAC into the deferral bucket.” But while IEU
    explains why it does not like that decision, it neither cites legal authority
    prohibiting the commission’s approach nor persuasively explains how the order
    was objectively unreasonable. That is not enough to demonstrate reversible error.
    {¶ 69} We reject IEU’s sixth proposition of law.
    J. IEU Proposition of Law 7: IEU fails to demonstrate any violation
    of R.C. 4903.09’s requirement of a reasoned explanation.
    {¶ 70} Last, in its seventh proposition of law, IEU alleges that the
    commission violated R.C. 4903.09 by failing to sufficiently detail “the reasons
    prompting the decisions arrived at.” R.C. 4903.09. IEU lodges this objection at
    a fatally high level of generality.     Had the commission issued a one-page
    summary order to resolve this case, it might suffice to assert simply that “the
    Orders omit the required documentation of the Commission’s reasoning.” But the
    order and entries on rehearing fill 140 pages—while we do not equate breadth
    with depth, IEU must do more to show error.
    {¶ 71} Given the rehearing requirements, IEU needs to show at least three
    things to prevail under R.C. 4903.09: first, that the commission initially failed to
    explain a material matter; second, that IEU brought that failure to the
    commission’s attention through an application for rehearing; and third, that the
    commission still failed to explain itself. IEU’s nonspecific allegations establish
    none of these points. (The only example developed by IEU concerns the POLR
    charge, which we have already discussed.)
    21
    SUPREME COURT OF OHIO
    {¶ 72} IEU has not specifically explained how the commission failed to
    explain itself. On that basis, we reject its seventh proposition of law.
    III. Conclusion
    {¶ 73} Some of the issues raised are best left to the General Assembly,
    which has the responsibility to monitor the development and implementation of
    the new regulatory regime. We can resolve legal disputes, but we cannot fill
    gaps. While our goal is always to determine the intent of the General Assembly,
    we also recognize that our decisions may reveal gaps unintended by that body. If
    that occurs, or the law otherwise fails to achieve its policy objectives, the
    legislature is the appropriate body to determine those issues.
    {¶ 74} For the foregoing reasons, we reverse in part, affirm in part, and
    remand this case to the commission.
    Order affirmed in part
    and reversed in part,
