    ADVOCATING FOR TARIFF EQUITY,
    Appellees.
    Before: LETICA, P.J., and M. J. KELLY and BOONSTRA, JJ.
    BOONSTRA, J.
    Petitioner appeals by right the April 12, 2018 order of the Public Service Commission
    (PSC) authorizing petitioner to adopt a rate increase. We affirm.
    I. PERTINENT FACTS AND PROCEDURAL HISTORY
    The issues in this case arise following the enactment of 
    2016 PA 341
    , sometimes
    informally called “Act 341,” through which the Legislature amended the PSC’s enabling act,
    MCL 460.1 et seq.1 The PSC’s April 12, 2018 order includes a concise summary of the
    proceedings leading to the decision below:
    1
    The amendments included the addition of MCL 460.6w, in furtherance of this state’s resolve to
    encourage both competition and alternative energy sources in the provision of electricity, while
    guaranteeing reliability of service. We will discuss that provision in greater detail later in this
    opinion.
    -1-
    On May 15, 2017, [petitioner] filed an application seeking authority to
    increase its rates for the sale of electric energy, approval of depreciation accrual
    rates, and other related matters. The rate increase sought in this proceeding is
    based on the company’s projections for relevant items of investment, expenses,
    and revenues for a test year covering the calendar year ending December 31,
    2018. In its application, [petitioner] averred that, without rate relief, the company
    will experience a jurisdictional electric revenue shortfall of $51,700,000, on an
    annual basis, during the test year.
    * * *
    According to [petitioner], the net impact of all matters to be considered in
    this proceeding supports the company’s requested rate relief of $51,700,000. The
    company maintained that, absent rate relief in this amount, it will experience
    revenues so low as to deprive it of a reasonable return on its investments in
    violation of the federal and state constitutions.
    Administrative Law Judge Mark E. Cummins (ALJ) held a prehearing
    conference on June 22, 2017. At the prehearing conference, the ALJ granted
    petitions to intervene filed by the Michigan Department of the Attorney General
    (Attorney General) and [the Association of Businesses Advocating for Tariff
    Equity (ABATE)]. The Commission Staff (Staff) also participated.
    An evidentiary hearing was held on November 15, 2017, after which
    timely briefs and reply briefs were filed. On February 8, 2018, the ALJ issued his
    Proposal for Decision (PFD). The parties filed exceptions to the PFD on February
    26, 2018, and replies to exceptions on March 8, 2018.
    The PSC granted petitioner’s request for rate relief, but applied the “net CONE [Cost of
    New Entry]” methodology to adjust certain costs related to petitioner’s provision of “capacity”
    services to customers who have chosen an alternative electric supplier. It therefore granted rate
    relief in the amount of $49,895,000.2 The order granting the rate relief further specified that the
    new rates would go into effect two weeks after the order was entered.
    This appeal followed. On appeal, petitioner challenges two aspects of the PSC’s order:
    (1) the two-week delay in implementation; and (2) the use of the CONE methodology. This
    Court granted the motion of the Michigan Electric and Gas Association (MEGA) to file a brief as
    amicus curiae.3
    2
    This April 12, 2018 order authorized a rate increase in the amount of $49,118,000, but an
    April 27, 2018 amendatory order corrected the amount of the rate increase to $49,895,000.

    II. STANDARD OF REVIEW
    This Court’s standard of review for PSC orders is narrow and well defined. Under
    MCL 462.25, “[a]ll rates, fares, charges, classification and joint rates fixed by the [PSC] and all
    regulations, practices, and services prescribed by the [PSC]” are presumed to be lawful and
    reasonable. See also Mich Consol Gas Co v Pub Serv Comm, 
    389 Mich. 624
    , 635-636; 209
    NW2d 210 (1973). A reviewing court should defer to the PSC’s administrative expertise in
    reviewing an order setting rates, and should not substitute its judgment for that of the PSC.
    Attorney General v Pub Serv Comm No 2, 
    237 Mich. App. 82
    , 88; 602 NW2d 225 (1999).
    However, a final order of the PSC must be authorized by law and must be supported by
    competent, material, and substantial evidence on the whole record. Const 1963, art 6, § 28; In re
    Consumers Energy Co, 
    279 Mich. App. 180
    , 188; 756 NW2d 253 (2008). A party aggrieved by
    an order of the PSC has the burden of proving by clear and convincing evidence that the order is
    unlawful or unreasonable. MCL 462.26(8). To establish that a PSC order is unlawful, the
    appellant must show that the PSC failed to follow a statutory requirement or abused its discretion
    in the exercise of its judgment. In re MCI Telecom Complaint, 
    460 Mich. 396
    , 427; 596 NW2d
    164 (1999).
    Whether the PSC exceeded the scope of its authority is a question of law that we review
    de novo. In re Complaint of Pelland Against Ameritech Mich, 
    254 Mich. App. 675
    , 682; 658
    NW2d 849 (2003). This includes issues of statutory interpretation. In re Complaint of Rovas,
    
    482 Mich. 90
    , 102; 754 NW2d 259 (2008). We give an administrative agency’s interpretation of
    relevant statutes respectful consideration, but not deference. 
    Id. at 108.
    III. DELAYED IMPLEMENTATION OF NEW RATES
    Petitioner and amicus MEGA argue that the PSC erred by ordering that the rate relief it
    granted in its April 12, 2018 order apply only to service provided on and after April 26, 2018,
    i.e., that the order essentially not take effect until that later date. We disagree.
    MCL 460.6a(1) conditions changes in rates or rate schedules by regulated gas or electric
    utilities on PSC approval. MCL 460.6a(5) requires that the PSC make a “final decision with
    respect to a completed petition or application to increase or decrease utility rates within the 10-
    month period following the filing of the completed petition or application;” otherwise, “the
    petition or application is considered approved.” That subsection further provides that where the
    petitioning utility “makes any significant amendment to its filing, the commission has an
    additional 10 months after the date of the amendment to reach a final decision, and also that “[i]f
    the utility files for an extension of time, the commission shall extend the 10-month period by the
    amount of additional time requested by the utility.”
    In this case, the parties stipulated to extend the 10-month period by 28 days, and the PSC
    entered its April 12, 2018 order granting rate relief precisely 10 months and 28 days after
    petitioner filed its petition, i.e., on the last day available for a timely decision under
    MCL 460.6a(5). Although that order, as adjusted by the April 27 amendatory order,
    substantially granted petitioner’s request for a rate increase, it declared that petitioner “is
    authorized to implement the rates approved by this order on a service rendered basis for service
    provided on or after April 26, 2018.” Petitioner argues that the two-week implementation delay
    -3-
    will cost it $1.9 million, to which it claims it is entitled, which amount petitioner arrived at by
    calculating the weekly average of the total annual increase and then doubling that value.
    Petitioner also argues that by delaying implementation of the new rates by two weeks, the PSC
    was attempting to extend the statutory period available for it to reach a decision, and that the
    April 12, 2018 order, as amended, should therefore not be considered a “final decision” for
    purposes of MCL 460.6a(5). The result would be that petitioner’s original petition should be
    deemed approved as filed. Both arguments hinge on the extent to which the PSC may issue an
    order providing that some of its aspects would not go into effect immediately. We conclude that
    the PSC acted within its authority in this case.
    A. COLLATERAL ATTACK
    Before addressing the issues raised by petitioner, we must first address the PSC’s
    contention that petitioner’s claim is an impermissible collateral attack on the PSC’s earlier
    decision in In the Matter, on the Commission’s Own Motion, to Revise the Standard Rate
    Application Filing Forms and Instructions (Case No. U-18238). In that case, the PSC undertook
    to reevaluate its standard filing requirements for rate cases following the enactment of Act 341.
    Among the issues considered was whether the PSC could give rates an effective date other than
    the date on which the rates were approved. In a footnote of a July 31, 2017 order, the PSC
    stated:
    MCL 460.6a(5) states that the Commission must “reach a final
    decision . . . within the 10-month period following the filing of [a] completed
    petition or application . . . .” (Emphasis added.) As a result, based on the
    Commission’s legal interpretation of this directive, the Commission finds that an
    order settling the rights of the parties and disposing of all issues in controversy in
    a rate case, aside from enforcement of that decision (i.e., the issuance of tariff
    sheets, determining the appropriate rate design, etc.), will, at the very least, be
    issued by the Commission within 10 months. . . . The Commission further finds
    that the distinction between the Legislature’s use of the words “reach a final
    decision” versus “issue a final order,” the latter of which is, in fact, used in a
    different context elsewhere within MCL 460.6a, also provides additional support
    for the Commission’s interpretation. [Case No. U-18238, Order Summarizing
    Investigation and Partially Closing Docket, p 6 n 8 (Footnote 8).
    In other words, the PSC distinguished between issuing a final decision and implementing that
    decision, and concluded that it did not need to implement a decision within the time frame within
    which the decision itself needed to be made. The Michigan Electric and Gas Association
    (MEGA) and Consumers Energy Company (Consumers) filed petitions seeking rehearing and
    clarification of the PSC’s language in Footnote 8, resulting in the PSC’s issuance of an order
    clarifying that statement on October 11, 2017. See Case No U-18238, order entered October 11,
    -4-
    2017.4 Neither MEGA nor Consumers further challenged or appealed the October 11, 2017
    order.
    A collateral attack occurs when a party uses “a second proceeding to attack a tribunal’s
    decision in a previous proceeding.” Worker’s Compensation Agency Director v MacDonald’s
    Industrial Prods, Inc (On Reconsideration), 
    305 Mich. App. 460
    , 474; 853 NW2d 467 (2014). A
    “collateral attack” on a previous decision is generally impermissible; a party aggrieved by a
    decision in an earlier proceeding instead has resort to the appellate process in the context of that
    same proceeding. See 
    id. at 475.
    Only decisions that are void for lack of subject matter or
    personal jurisdiction may be collaterally attacked. 
    Id. The PSC
    argues that, because petitioner
    did not raise any objections in connection with the orders in Case No. U-18238, and did not
    appeal the PSC’s conclusions in Footnote 8, petitioner should be precluded from attacking in this
    case the PSC’s determination that a timely final decision may include a provision for delayed
    implementation of its terms. In the context before us, we disagree.
    The PSC acknowledges that Case No. U-18238 was not a contested rate case; instead, it
    was a unilateral revisiting by the PSC of certain of its procedures in the wake of the passage of
    Act 341. Although the PSC’s decision in that case was issued with an extensive distribution list,
    which included petitioner, it did not actually decide any rights or responsibilities of petitioner or
    any other entity. Footnote 8 of that decision, and the PSC’s later clarification of it, merely
    asserted in the abstract that the PSC believed it was able to delay implementation of a final
    decision in a ratemaking case. In fact, the PSC itself calls Case No. U-18238 a “case with no
    monetary impact” on petitioner and one in which “the stakes were low compared to a rate case
    with tens of millions of dollars at stake.” At the time the orders in Case No. U-18238 were
    entered, petitioner was not a party to the case whose rights were being adjudicated, but rather
    was merely invited to submit comments or objections as an interested person; moreover,
    petitioner was not “aggrieved” by the PSC’s abstract statement of law found in Footnote 8 (and
    the later clarification), see Worker’s Compensation Agency Director (On 
    Reconsideration), 305 Mich. App. at 475
    , and it is far from clear that petitioner would have possessed standing to take an
    appeal from the PSC’s orders in that case. See MCR 7.203(A), (B). Under these circumstances,
    we conclude that the collateral attack doctrine does not bar petitioner’s claim relating to delayed
    implementation.
    The PSC further argues that, if the collateral attack doctrine does not apply, this Court
    should nonetheless apply some form of issue preclusion to bar petitioner’s claim in the manner
    of a claim barred by collateral estoppel. We disagree.
    4
    In its October 11, 2017 order, the PSC referred to an earlier case in which its final order was
    issued 8 days after its final decision, clarifying that “footnote 8 was intended to be transparent in
    notifying stakeholders that the Commission plans on having the preparation, review, and
    approval of final tariff sheets conforming to the Commission’s final decision handled in an
    expeditious manner after the issuance of the final decision.”

    “Collateral estoppel bars relitigation of an issue in a new action arising between the same
    parties or their privies when the earlier proceeding resulted in a valid final judgment and the
    issue in question was actually and necessarily determined in that prior proceeding.” Leahy v
    Orion Twp, 
    269 Mich. App. 527
    , 530; 711 NW2d 438 (2006), citing 1 Restatement Judgments,
    2d, § 27, p 250. However, this Court has noted, and the PSC concedes, that “ratemaking is a
    legislative, rather than a judicial, function, and thus the doctrines of res judicata or collateral
    estoppel ‘cannot apply in the pure sense.’ ” In re Application of Consumers Energy Co for Rate
    Increase, 
    291 Mich. App. 106
    , 122; 804 NW2d 574 (2010) (quotation marks and citation
    omitted). Our Supreme Court has also noted that courts are reluctant to apply preclusion
    doctrines when questions of law are involved and the causes of action do not arise from the same
    subject matter or transaction. Young v Edwards, 
    389 Mich. 333
    , 339; 207 NW2d 126 (1973).
    Further, “A question has not been actually litigated until put into issue by the pleadings,
    submitted to the trier of fact for a determination, and thereafter determined.” VanDeventer v
    Mich Nat’l Bank, 
    172 Mich. App. 456
    , 463; 432 NW2d 338 (1988).
    As noted, Case No. U-18238 was not a contested rate case, and did not actually decide
    any rights or responsibilities of any party. Footnote 8 (and the later clarification) merely asserted
    as an abstract legal proposition, and without applying the conclusion to any set of facts, that the
    PSC was able to delay implementation of a final decision in a ratemaking case. The mere fact
    that no utility elected to expend resources to challenge that footnoted statement (beyond the
    clarification given by the PSC) does not mean that the issue was actually litigated. 
    Id. We decline
    to apply preclusion principles to petitioner’s claim in this case.
    Accordingly, although the question of the PSC’s prerogative to issue a final order that
    includes some delay in its implementation was abstractly addressed in Case No. U-18238, we
    conclude that petitioner’s claim in this case is not an impermissible collateral attack on the PSC’s
    decision in that earlier case. Further, the matter was not fully litigated in that case, and collateral
    estoppel would not apply in this situation even if the doctrine were fully applicable in this appeal
    of a ratemaking order. Accordingly, petitioner is not precluded from raising this issue.
    B. FINAL DECISION
    Notwithstanding that petitioner is not precluded from raising this issue, we conclude that
    the PSC was permitted to issue a final decision with delayed implementation in this case.
    Petitioner argues that the PSC erred by purporting to issue a final decision in the form of an order
    approving rate relief while delaying implementation of the new rates by two weeks. We
    disagree.
    Resolution of this issue requires us to interpret the language of MCL 460.6a(5). When
    interpreting a statute, our goal is to ascertain and give effect to the intent of the Legislature.
    Mich Ed Ass’n v Secretary of State (On Rehearing), 
    489 Mich. 194
    , 217; 801 NW2d 35 (2011).
    Our starting point is the language of the statute itself. United States Fidelity Ins & Guaranty Co
    v Mich Catastrophic Claims Ass’n (On Rehearing), 
    484 Mich. 1
    , 13; 795 NW2d 101 (2009). The
    Legislature is presumed to have intended the meaning it plainly expressed, Joseph v Auto Club
    Ins Ass’n, 
    491 Mich. 200
    , 206; 815 NW2d 412 (2012), and clear statutory language must be
    enforced as written, Velez v Tuma, 
    492 Mich. 1
    , 16-17; 821 NW2d 432 (2012); People v Dowdy,
    
    489 Mich. 373
    , 379; 802 NW2d 239 (2011).
    -6-
    MCL 460.6a(5) provides:
    Except as otherwise provided in this subsection and subsection (1), if the
    commission fails to reach a final decision with respect to a completed petition or
    application to increase or decrease utility rates within the 10-month period
    following the filing of the completed petition or application, the petition or
    application is considered approved. If a utility makes any significant amendment
    to its filing, the commission has an additional 10 months after the date of the
    amendment to reach a final decision on the petition or application. If the utility
    files for an extension of time, the commission shall extend the 10-month period
    by the amount of additional time requested by the utility.
    The plain language of MCL 460.6a(5) provides that the PSC must “reach a final
    decision” on a petition or application within the prescribed time frame; it does not say that any
    increase or decrease in utility rates ordered in response to that petition or application must be
    fully implemented within that time frame. As discussed below, we conclude that a significant
    difference exists between a “final decision” and the ultimate implementation of that decision,
    such that the phrase “final decision” cannot reasonably be read to encompass full
    implementation.
    As stated earlier in this opinion, and while not binding on our statutory interpretation, the
    PSC in Footnote 8 of its July 31, 2017 order in Case No. U-18238 cited Black’s Law Dictionary
    (7th ed, 1999) and distinguished “final decision” from “final order,” stating that a “final
    decision” from the PSC is “an order settling the rights of the parties and disposing of all issues
    in controversy in a rate case, aside from enforcement of that decision.” In its October 11, 2017
    order, the PSC reaffirmed its conclusion that the terms “final decision” and “final order” have
    different meanings, noting that “[p]er Black’s Law Dictionary, ‘final decision’ is defined as ‘[a]
    court’s last action that settles the rights of the parties and disposes of all issues in controversy,
    except for the award of costs (and, sometimes, attorney’s fees) and enforcement of the
    judgment,’ whereas ‘final order’ is defined as ‘[a]n order that is dispositive of the entire case.’ ”
    These definitions recognize a difference between finality in the decision-making process and
    finality in implementation of that decision.
    Although our court rules do not distinguish “final decision” from “final order,” they do
    define a “final order” appealable by right as, but for exceptions not applicable here, “the first
    judgment or order that disposes of all the claims and adjudicates the rights and liabilities of all
    the parties.” MCR 7.202(6)(a)(i). And, when considering the question of “finality” for purposes
    of appealability, our Supreme Court has held that whether an order has “immediate and
    significant effect” is not dispositive of the question, and that there is “nothing inherently
    inconsistent with an order being ‘final’ . . . for one purpose and not another.” Great Lakes Steel
    v Pub Serv Comm, 
    416 Mich. 166
    , 180; 330 NW2d 380 (1982).
    In light of this, we conclude that the PSC’s April 12, 2018 order was a “final decision”
    within the meaning of MCL 460.6a(5). Moreover, the statutory obligation was for the PSC to
    reach a “final decision” within the prescribed time frame, not that its decision regarding rate
    relief must be fully implemented within that time frame. If the Legislature had intended that the
    PSC’s decision on a petition or application be fully implemented by the time frame prescribed in
    -7-
    MCL 460.6a(5), it could have easily said so; we will not read such a requirement into the clear
    language of the statute. See Mich Ed 
    Ass’n, 489 Mich. at 218
    . The PSC was not required to treat
    petitioner’s petition as accepted merely because it entered an order granting rate relief that would
    not take immediate effect.
    C. CONFISCATORY RATES
    Petitioner also argues that, even if the PSC acted within its authority in delaying
    implementation of the requested rate relief, it was damaged by that delay and should be
    compensated for what it argues were two weeks of “confiscatory” rates. We disagree.
    “A public utility has a right to a just and reasonable rate of return on its investment,” and
    such utilities “are protected from being limited to rates that are confiscatory.” ABATE v Pub
    Serv Comm, 
    208 Mich. App. 248
    , 269; 527 NW2d 533 (1994). As petitioner points out, our
    Supreme Court has stated that “[e]very day a warranted rate increase is withheld is a day in
    which justice has been denied . . . .” Mich Consol Gas Co v Pub Serv Comm, 
    389 Mich. 624
    ,
    637; 209 NW2d 210 (1973). However, Mich Consol Gas Co does not stand for the proposition
    that a decision recognizing a utility’s entitlement to a rate increase must be given immediate
    effect in all circumstances.5 Our Supreme Court has acknowledged that “[a] public utility has a
    substantive right, set forth in the statutes and rooted in the constitution, to rate relief where the
    revenue produced by an existing rate structure is less than the amount required by the statutes or
    the constitution,”6 and that this includes “a right to immediate relief where compelling
    circumstances indicate that such relief is necessary.” Consumers Power Co v Pub Serv Comm,
    
    415 Mich. 134
    , 145; 327 NW2d 875 (1982) (citations omitted). Although the Court in
    Consumers Power Co ultimately approved the circuit court’s decision to grant a temporary
    injunction to allow immediate collection of higher rates in order to prevent irreparable harm to a
    utility determined to be entitled to such rate relief, 
    id. at 154-156,
    the Court recognized the
    general principle that, absent compelling circumstances that demonstrate a utility’s entitlement to
    immediate rate relief, “[t]he power to decide whether any rate relief should be provided and
    whether immediate relief shall be provided is vested in the commission.” 
    Id. at 145.
    In this case, petitioner does not argue that Supreme Court’s statements in Consumers
    Power Co concerning the PSC’s prerogative to decide whether to grant immediate rate relief do
    not apply. Instead, petitioner simply states that “rate relief without delay” was “the practice that
    existed before the decision” in that case, and that it “remained the more common practice up
    5
    The issue addressed in Mich Consol Gas Co was the constitutionality of a statutory limitation
    on judicial review of a PSC decision, and the Court in that case notably added the following
    qualifier to the above-quoted language, “unless judicial action, as in this case, can be taken.” No
    such issue is present in this case.
    6
    “Both the Michigan Constitution and the United States Constitution preclude the government
    from depriving a person of life, liberty, or property without due process of law.” Reed v Reed,
    
    265 Mich. App. 131
    , 159; 693 NW2d 825 (2005). See also US Const, Am XIV, § 1; Const 1963,
    art 1, § 17.
    -8-
    until now.” Even if immediate rate relief is indeed “the more common practice,” petitioner does
    not explain why the PSC should have been required to follow that practice in this particular
    instance.
    Petitioner notes that under MCL 462.25, “[a]ll rates, fares, charges, classification and
    joint rates fixed by the commission and all regulations, practices and services prescribed by the
    commission shall be in force and shall be prima facie, lawful and reasonable until finally found
    otherwise in an action brought for the purpose . . ., or until changed or modified by the
    commission . . . .” However, nothing in the statutory language requires that a rate-relief order
    must require immediate implementation.
    Petitioner argues that if we conclude that the PSC has the ability to delay implementation
    of rate relief it has granted, there is nothing to stop it in the future from exceeding the two-week
    delay at issue in this case and to prescribe delays of much longer periods. However, a utility
    affected by a delay in implementation remains free to argue that a particular delay is “arbitrary,
    capricious, or an abuse of discretion” under MCL 24.306(1). In this case, petitioner complains
    that the PSC offered no explanation for the two-week delay in question, but stops short of
    arguing that the lack of explanation rendered that delay arbitrary, capricious, or an abuse of
    discretion. Accordingly, the propriety of the reasons underlying the unexplained delay is not
    before this Court, nor does a delay of 14 days in implementing a decision that was 11 months in
    the making strike this Court as per se arbitrary, capricious, or an abuse of discretion.
    Finally, appellee ABATE argues that petitioner’s calculation that the two-week delay will
    cause it to in incur a $1.9 million shortfall in revenue is speculative. We agree. Petitioner
    cannot state with certainty at this juncture, merely because it could have collected a higher rates
    for those two weeks if the PSC had ordered immediate implementation, that its inability to do so
    would cause an actual shortfall of a particular amount, or that the delay in implementation would
    deny it a “just and reasonable rate of return on its investment,” 
    ABATE, 208 Mich. App. at 269
    .
    We agree with ABATE that the delay at issue cannot necessarily be equated with a $1.9 million
    shortfall in revenue. Moreover, we cannot conclude that the two-week implementation delay
    necessarily imposes confiscatory rates in the interim. 7
    For these reasons, we hold that the PSC did not exceed its authority by including within
    its April 12, 2018 order granting rate relief, as amended, a two-week delay in implementation.
    IV. METHODOLOGY FOR CALCULATING CAPACITY COSTS
    Petitioner also argues that the PSC erred by applying the “net CONE” methodology to
    calculate the capacity costs that petitioner was entitled to recoup. We disagree.
    7
    The PSC notes that “although [it] found a rate increase appropriate to account for planned
    capital investments and increasing operating expenses,” it “never suggested that [petitioner’s]
    existing rate was confiscatory or lower than the lowest reasonable rate.”
    -9-
    MCL 460.6a(4) authorizes the PSC to establish procedures for considering and deciding
    utilities’ petitions to raise rates, and requires the PSC to “authorize a utility to recover the cost of
    fuel, purchased gas, or purchased power only to the extent that the purchases are reasonable and
    prudent.” The statute does not specify how the PSC is to determine a utility’s costs, or what is
    reasonable and prudent, and so this Court has generally deferred to the PSC’s decisions
    concerning such methodology. See Attorney General v Pub Serv Comm, 
    262 Mich. App. 649
    ,
    655, 658; 686 NW2d 804 (2004). “The PSC is entitled to consider ‘all lawful elements’ in
    determining rates . . . .” Detroit Edison Co v Pub Serv Comm, 
    221 Mich. App. 370
    , 385; 562
    NW2d 224 (1997), citing MCL 460.557(2); MCL 460.6a(2). Further, “[t]he PSC is not bound by
    any single formula or method and may make pragmatic adjustments when warranted by the
    circumstances.” Detroit 
    Edison, 221 Mich. App. at 375
    .
    An “alternative electric supplier” (AES) is an entity other than a public utility selling
    electric generation service to retail customers. MCL 460.10g(1)(a). “Capacity obligations”
    refers to an electric provider’s duty to ensure that it has the means to provide electricity to its
    customers “as set by the appropriate independent system operator, or commission.”
    MCL 460.6w(8)(a). Although some consumers in this state have the option of obtaining
    electricity from an AES, petitioner remains obligated to make available its transmission and
    distribution facilities for that purpose, and also retains a role in ensuring that AESs have
    sufficient capacity to consistently meet their customers’ needs. Because petitioner incurs costs
    related to these AES customers, it is permitted to incorporate a “capacity charge” into its rates.
    At issue in this dispute is whether the PSC correctly calculated the capacity charge to
    include costs that petitioner was entitled to recover while excluding charges that are a not
    recoverable by means of a capacity charge. MCL 460.6w sets forth provisions intended to
    ensure that electric suppliers maintain sufficient capacity to meet their customers’ needs
    consistently. MCL 460.6w(3) directs the PSC to establish a capacity rate to be applied to
    alternative electric load, and, in order to “ensure that noncapacity electric generation services are
    not included in the capacity charge,” requires the PSC to “include the capacity-related generation
    costs included in the utility’s base rates, surcharges, and power supply cost recovery factors,”
    and “subtract all non-capacity-related electric generation costs . . . .” See MCL 460.6w(3)(a),
    (b).
    We do not read this language as mandating the use of “actual costs” according to the
    method proposed by petitioner. Moreover, as ABATE notes, it is not clear that MCL 460.6w
    even applies to petitioner inasmuch as it appears on its face only to apply to tariffs established
    under the Midcontinent Independent System Operator (MISO), a Regional Transmission
    Organization (RTO) that operates as an alternative to PJM Interconnection, LLC (PJM), which is
    the RTO within whose jurisdiction petitioner operates. See, e.g., MCL 460.6w(12)(a) (defining
    “[a]ppropriate independent system operator” to mean MISO). Indeed, MCL 460.6w(11)
    expressly states,
    Nothing in this act shall prevent the [PSC] from determining a generation capacity
    charge under the reliability assurance agreement, rate schedule FERC No. 44 of
    the independent system operator known as PJM Interconnection, LLC, as
    approved by the Federal Energy Regulatory Commission in docket no. ER 10-
    2710 or similar successor tariff.
    -10-
    Accordingly, the PSC’s April 12, 2018 order in this case indicated that the PSC “agrees with
    [petitioner] that nothing in Act 341 requires that [petitioner’s] capacity rate be set using the
    mechanism set forth in the statute.” Rather, the PSC concluded that “subsections (a) and (b) of
    Section 6w(3) provide guidance . . . for determining capacity costs and rates.”
    Petitioner does not contest this reading of the statute, but instead argues that MCL 460.11
    in any event “requires the [PSC] to set rates based on cost of service.” MCL 460.11 states that,
    but for exceptions not here applicable, the PSC “shall ensure the establishment of electric rates
    equal to the cost of providing service to each customer class,” and sets forth a methodology for
    making such calculation while providing that the PSC “may modify this method if it determines
    that this method of cost allocation does not ensure that rates are equal to the cost of service.”
    In considering petitioner’s calculation of recoverable capacity charges, the PSC
    expressed concern that petitioner’s proposed methodology would include costs not actually
    related to capacity. The PSC determined, based on its staff’s analysis, that the appropriate
    methodology was to “identify production costs and then only consider those corresponding to the
    cost of a [combustion-turbine plant] as capacity-related.” The PSC further noted that its staff
    “contended that [petitioner] should be permitted to recover only the costs that are directly related
    to capacity service,” which thus meant the “exclusion of some production-demand classified
    costs,” and suggested that “the proper cost of capacity is the Cost of New Entry (CONE), or the
    cost to build a combustion turbine (CT).” The PSC quoted its staff in elaborating as follows:
    The characteristics of a CT are such that it effectively supplies only capacity. A
    CT is relatively expensive to run to produce energy, but relatively inexpensive to
    build. Therefore, it is only economically utilized to supply energy in those hours
    when load is at its highest. These hours are also those which are considered to set
    the capacity need of the utility to serve its customers. Plants other than CTs are
    more expensive to build and less expensive to run, making them the most cost-
    effective choice only if they run enough hours a year so that the total cost is
    lower. Therefore, the difference between the cost to build a CT and any other
    type of plant is the capital cost expended to produce lower energy costs. In
    Staff’s opinion, this cost should properly be considered an energy cost. However,
    the net sales to the market should be applied as an offset to the capacity-related
    costs. As all energy is bid into the market at the cost to run a plant, but plants are
    paid if dispatched at the highest bid called in the supply stack, these net-energy
    market sales (imperfectly) capture what Staff would consider to be the energy
    related portion of capacity costs. Therefore, to remove all costs above a CT and
    then apply an offset which effectively, if imperfectly, does the same, would be
    double counting the offset.
    Petitioner argues that the PSC’s chosen methodology deviated from the requirement to
    base rates on actual costs. However, the record shows that the PSC recognized the problem of
    isolating the costs of providing capacity to AESs to ensure their reliability, which petitioner was
    entitled to recover, from ordinary operating costs. The PSC’s chosen methodology was intended
    to address that issue. Again, we generally defer to the PSC regarding such decisions. See
    MCL 460.6a(4); Attorney 
    General, 262 Mich. App. at 655
    .
    -11-
    Petitioner suggests that instead of resorting to the net CONE to calculate costs, the PSC
    should simply have stricken from petitioner’s proposal any costs it deemed not properly part of
    the calculation and otherwise stayed with petitioner’s approach. Even if petitioner’s proposed
    methodology was a reasonable choice, it is the PSC’s prerogative to choose among competing
    methodologies for such calculations. See MCL 460.6a(4); Attorney 
    General, 262 Mich. App. at 655
    .
    Petitioner protests that the use of net CONE constituted a departure from long prevailing
    precedent. Petitioner cites cases to show previously prevailing practice, but cites no authority for
    the proposition that the PSC, having once applied a methodology, does not have discretion to
    reconsider the matter in subsequent cases. Instead, petitioner asserts that the PSC offered no
    reason for the change, and thus that the use of net CONE was arbitrary and capricious. We
    disagree.
    As stated, the PSC noted that, under MCL 460.6w(11), the PSC retained the prerogative
    of “determining a generation capacity charge,” and also that “nothing in Act 341 requires that
    [petitioner’s] capacity rate be set using the mechanism set forth in the statute.” The PSC
    nonetheless took guidance from the direction in MCL 460.6w(3) that the PSC establish a
    capacity rate “to be applied to alternative electric load,” and also to “ensure that noncapacity
    electric generation services are not included in the capacity charge” by requiring the PSC under
    Subdivision (a) to “include the capacity-related generation costs included in the utility’s base
    rates, surcharges, and power supply cost recovery factors,” and under Subdivision (b) to
    “subtract all non-capacity-related electric generation costs . . . .”
    In this case, the PSC announced that it found it “appropriate to revisit the methodology”
    it had approved in an earlier case. It also set forth extensive explanations, including that not “all
    production capacity-related costs are incurred to provide capacity,” and offered exhibits to show
    “that the rates calculated for [AES customers] and standard service customers using net CONE
    do not differ,” in support of its conclusion that net CONE is reasonable because it “begins with
    total embedded production-related costs and subtracts non-capacity-related costs.” The PSC also
    indicated that it “may revisit, in a future rate case, whether to retain this net CONE
    methodology” or revert to “using fixed costs offset by fuel and other revenues.”
    Our review of the record reflects that the issue of the appropriate methodology for
    determining capacity costs was extensively litigated in this case, was the subject of an extensive
    evidentiary record, including expert testimony, was thoroughly briefed by the parties, and was
    the subject of intense and detailed analysis by the PSC. In its order, the PSC presented at length
    the reasoning underlying its choice of methodology, and the problems it was attempting to
    address; its reasoning was not unlawful, unreasonable, or unsupported by evidence. For these
    reasons, petitioner has not shown that the PSC failed to follow a statutory requirement or abused
    its discretion in the exercise of its judgment when it chose to employ the net CONE methodology
    for the purpose of separating petitioner’s general operating costs from its costs in supplying
    capacity to AESs as required for the latter to guarantee their ability to meet their customers’
    needs at times of highest demand. Accordingly, we defer to that decision. MCI Telecom
