    STATE CORPORATION COMISSION, ET AL.
    FROM THE STATE CORPORATION COMMISSION
    Appalachian Power Company (“Appalachian”) and the Office of the Attorney General,
    Division of Consumer Counsel (“Consumer Counsel”), 1 both challenge different rulings made by
    the State Corporation Commission (“Commission”) during its triennial review of Appalachian’s
    rates, terms, and conditions pursuant to Code § 56-585.1. For the following reasons, we reverse
    in part, affirm in part, and remand for further proceedings consistent with this opinion.
    I. BACKGROUND
    A. Triennial Review
    Under Code § 56-585.1, the Commission is required to conduct a review every three
    years 2 of Appalachian’s rates, terms, and conditions for providing generation, distribution, and
    transmission services. The Commission must determine Appalachian’s earned return for the
    1
    Consumer Counsel is joined by Sierra Club and the Virginia Poverty Law Center in its
    appeal, but for the sake of brevity, all appellants in Record No. 210634 will be referenced
    collectively as “Consumer Counsel” throughout this opinion.
    2
    These reviews were previously conducted on a biennial basis, but in 2015, the General
    Assembly enacted legislation that canceled Appalachian’s biennial review scheduled for 2016,
    froze its rates, and scheduled the next review for 2020, which would cover the years 2017-2019.
    See Code § 56-585.1:1(A). The years of 2015 and 2016, which were not covered by any review,
    are referred to as the “transitional-rate period.” Appalachian’s last review was in 2014.
    three-year period and then compare it to a 140-point band around Appalachian’s approved return
    on equity (“ROE”). Code § 56-585.1(A)(8). If the earnings fall more than 70 points below or
    above the approved ROE, the Commission must conduct a going-forward rate case to determine
    how much to adjust rates. If the earnings are more than 70 points below the approved ROE, the
    Commission must order an increase in the rates to recover the revenue reduction, and if the
    earnings are more than 70 points above the approved ROE, the Commission must order bill
    credits for customers. See Code § 56-585.1(A)(8)(a)-(b). But if the earnings fall within the 140-
    point band, the statute dictates that the Commission does not conduct a going-forward rate case
    and that no bill credits are issued. See Code § 56-585.1(A)(8).
    On March 31, 2020, Appalachian filed its application with the Commission for a triennial
    review pursuant to Code § 56-585.1. For the 2017-2019 triennial-review period at issue in this
    case, Appalachian’s approved ROE was 9.42%. In its application, Appalachian requested an
    increase in its base rates totaling nearly $65 million because its earnings were more than 70
    points below its authorized ROE for the triennial-review period. Appalachian claimed that it had
    earned a return of 8.24% on its common equity, which was the equivalent of $23.6 million in
    pre-tax earnings below 8.72%, the bottom of its authorized ROE band.
    In its application, Appalachian explained that its earnings during the test period reflected
    the recordation of three different costs authorized by Code § 56-585.1(A)(8). Appalachian
    recorded $88.3 million in December 2019 for “the remaining Virginia jurisdictional share of
    certain impaired coal generating assets that were retired early,”3 which referred to several coal-
    3
    The total impairment cost recorded on Appalachian’s books was $93 million, but the
    Virginia retail share subject to the Commission’s jurisdiction was $88.3 million. See 6 J.A. at
    2904-05. See generally Code § 56-581(A).
    2
    fired power plants, or portions thereof, that were retired in 2015. 1 J.A. at 15. Appalachian also
    recorded $32.6 million for costs associated with severe weather events and $33.7 million for
    costs associated with projects necessary to comply with laws and regulations related to coal
    combustion by-product management. According to Appalachian, these three combined
    categories of costs resulted in its triennial earnings falling below the ROE band by $23.6 million,
    which was the reason it was requesting a 6.5% residential rate increase for the next 3 years.
    Appalachian also asked the Commission to adjust its authorized ROE going forward to
    9.9% instead of the existing 9.42%. Appalachian argued that this increase was necessary to
    reflect investment risks and the need for financial integrity and to ensure that it remained
    competitive with its peers. Lastly, Appalachian requested changes to existing rate schedules and
    certain terms and conditions to better reflect the costs incurred by the company. The
    Commission held an evidentiary hearing for Appalachian’s application from September 14-18,
    2020.
    B. Retirement of Coal-Fired Power Plants
    In 2011, Appalachian decided to retire early several of its coal-fired power plants, or
    portions thereof, in 2015. Appalachian’s 2010 depreciation study reflected retirement dates
    between 2015 and 2019 for these facilities. In 2014, Appalachian confirmed that the planned
    2015 retirements should be treated on the books as normal retirements (as opposed to
    abandonments) and included them in a new depreciation study filed as part of its 2014 biennial
    review.
    In 2015, Appalachian retired these units as planned and ceased recording depreciation on
    them in accordance with applicable accounting standards. The retired units at that time had a
    remaining net book value of $88.3 million for Virginia jurisdictional purposes. The company’s
    3
    July 2015 accounting memorandum referred to these retired units as “normal retirements” that
    were probable of future recovery and not “abandonment[s].” 6 id. at 2436.250. As a result,
    Appalachian did not record an impairment of the units’ remaining net book value in 2015. In
    2016, 2017, and 2018, Appalachian continued to report these units as normal retirements, not
    abandonments, and did not record an impairment. These decisions led to a significant
    depreciation-reserve deficiency.
    In December 2019, Appalachian recorded these retired units as asset impairments so that
    all remaining costs would be recorded within the current triennial-review period as permitted by
    statute. Code § 56-585.1(A)(8) provides that “costs associated with asset impairments related to
    early retirement determinations made by the utility for utility generation facilities fueled by
    coal,” which are “recorded per books by the utility for financial reporting purposes and accrued
    against income” and “not proposed for recovery under any other subdivision of this subsection,”
    “shall be attributed to the test periods under review and deemed fully recovered in the period
    recorded.” 4
    Appalachian explained in interrogatories submitted to the Commission’s Staff that it had
    recorded the asset impairment “[b]ased on management’s interpretation of Virginia law and more
    certainty regarding [Appalachian’s] triennial revenues, expenses and resulting earnings upon
    reaching the end of the three-year review period.” 6 J.A. at 2436.219; see also id. at 2436.226,
    2436.263. Appalachian’s accounting manager also stated in written testimony that the company
    had impaired these assets because, “based upon circumstances at that time,” the remaining costs
    4
    This subsection was amended in 2018 to remove the phrase “prior to December 31,
    2012” after “costs associated with asset impairments related to early retirement determinations
    made by the utility” and to add the phrase “and deemed fully recovered in the period recorded.”
    2018 Acts ch. 296, at 513.
    4
    of the units were no longer “probable of future recovery” under generally accepted accounting
    principles (“GAAP”) governing regulated operations because pursuant to Code § 56-
    585.1(A)(8), “such recorded costs are deemed to have been recovered from [Appalachian’s]
    customers through rates in effect during” the triennial-review period. Id. at 2902; see also 8 id.
    at 3271 (testifying at the five-day hearing before the Commission that management deemed these
    costs “no longer probable of future recovery” because Appalachian “had sufficient earnings to
    recover those through [its] current rates through this triennial period”). External auditors
    reviewed Appalachian’s financial statements between 2015 and 2019 and issued unqualified
    opinions that the financial statements conformed with GAAP, and Commission Staff admitted at
    the Commission hearing on Appalachian’s application that Appalachian recorded an asset
    impairment “[f]or financial reporting purposes,” 10 id. at 4240; see also 13 id. at 5660 (“Staff is
    not questioning the Company’s accounting or attempting to force the Company to account for
    costs in a specific way under GAAP.”).
    In its response to Appalachian’s application, Consumer Counsel’s accounting witness
    proposed expensing the entire $88.3 million prior to 2017 with none of the costs being expensed
    within the current triennial-review period. Commission Staff proposed a plan that would
    separately amortize the $88.3 million over 10 years, beginning in 2015, the year that the units
    were retired. Doing so would mean that approximately 30% of the costs would be expensed
    within the current triennial review.
    In rejecting Appalachian’s recording of the entire $88.3 million within the current
    triennial-review period, the Staff concluded that “[t]he event that triggered the 2019 write-off
    was an evaluation of [Appalachian’s] expected Triennial Period earnings, not an early retirement
    determination,” 5 id. at 2295; see also 10 id. at 4166-67, making the asset impairment not
    5
    “related to early retirement determinations” as defined by Code § 56-585.1(A)(8). A Staff
    witness testified at the Commission’s hearing on Appalachian’s application that the language of
    the statute “makes it clear” that an early retirement determination and the recording of an asset
    impairment “are connected” and should be made simultaneously or contemporaneously with
    each other. See 10 J.A. at 4241-43.
    The General Assembly passed House Bill 528 during the 2020 regular session, and after
    Appalachian had filed its triennial-review application, the Governor signed the bill, which
    became effective on July 1, 2020. The bill provides that the Commission must determine the
    amortization period for the recovery of any appropriate costs due to the early retirement of
    electric generation facilities and lays out certain factors that the Commission is required to
    consider in making that determination. See 2020 Acts ch. 662, at 994 (codified at Code § 56-
    585.1(E)). The parties disputed whether this bill was retroactive, making it applicable to
    Appalachian’s triennial review and affecting how the Commission handled Appalachian’s costs
    from the 2015 early retirement of some of its coal-fired power plants. This new legislation
    requires the Commission to establish an amortization period of recovery by “perform[ing] an
    independent analysis of the remaining undepreciated capital costs,” “establish[ing] a recovery
    period that best serves ratepayers,” and “allow[ing] for the recovery of any carrying costs that the
    Commission deems appropriate.” Code § 56-585.1(E).
    C. Inter-Company Power Agreement
    In 2011, the Commission approved Appalachian’s application to enter into an Inter-
    Company Power Agreement (“ICPA”) with Ohio Valley Electric Cooperation (“OVEC”). One
    of the conditions of this approval was that Appalachian pay the lower of OVEC’s cost or the
    market cost of non-affiliated power purchases for any energy and capacity purchases made under
    6
    the ICPA to serve its Virginia customers. See In re Appalachian Power Co., Case No. PUE-
    2011-00058, 
    2011 WL 3528704
    , at *2 (Va. S.C.C. Aug. 3, 2011). Appalachian was required to
    maintain records, available upon request, to show that any purchases it had made complied with
    this requirement. Appalachian purchased both energy and capacity under this ICPA.
    As part of Appalachian’s application, it presented evidence that its ICPA-energy costs
    were approximately $49 million below comparable market-energy costs. Appalachian did not
    provide similar evidence for comparable market-capacity costs, asserting that comparable data
    did not exist because it had purchased long-term capacity from OVEC and the only other market
    data was for short-term capacity. Instead of presenting market prices for capacity, Appalachian
    presented a 2011 Benchmark Study that demonstrated the costs of a comparable alternative to the
    long-term capacity (extending through 2040) that Appalachian had purchased under the ICPA —
    a “new build base-load power plant,” 6 J.A. at 2874. Consumer Counsel presented comparisons
    of the ICPA-capacity costs to market-capacity costs that allegedly indicated payments by
    Appalachian were above market value. Consumer Counsel recommended that the amount of
    ICPA-capacity costs above market-capacity costs be removed from Appalachian’s rates as
    excessive.
    D. 2017 Depreciation Study
    When the Commission conducted Appalachian’s 2014 biennial review, it denied
    Appalachian’s request to adjust depreciation rates for its coal-fired power plants and ruled that
    “depreciation rates should not be changed at this time” but that “the Commission [would] revisit
    this issue as part of [Appalachian’s] next biennial review.” In re Appalachian Power Co., Case
    No. PUE-2014-00026, 
    2014 WL 6851256
    , at *28 (Va. S.C.C. Nov. 26, 2014). The Commission
    made this decision because the EPA was in the process of adopting new rules that would “likely
    7
    affect the useful lives of all coal-fired plants” and that “could substantially impact the
    reasonableness of the depreciation studies and the resulting depreciation rates.” 
    Id.
    Accordingly, the Commission concluded that it would be reasonable to review depreciation rates
    at the next biennial review when the potential impacts of the EPA’s proposed regulations would
    be further known pursuant to the new rules that were expected to be issued by then. See 
    id.
     The
    General Assembly, however, subsequently enacted legislation freezing Appalachian’s rates and
    canceling the next biennial review scheduled for 2016. See Code § 56-585.1:1(A).
    Following the transitional-rate period, Commission Staff requested that Appalachian
    submit a study of depreciation rates for its assets as of December 31, 2017. Appalachian
    complied and provided Staff with the 2017 Depreciation Study. Appalachian, however, did not
    request approval for implementing the study’s proposed depreciation rates and rejected the
    Commission Staff’s request to implement the updated depreciation rates for 2018 and 2019
    based on the Staff’s revisions to the 2017 Depreciation Study. As part of its application,
    Appalachian calculated its depreciation expenses for 2018 and 2019 based on the depreciation
    rates approved by the Commission in 2012, not the depreciation rates produced by the 2017
    Depreciation Study and the Staff’s revisions.
    E. Commission’s Findings
    Following the evidentiary hearing on Appalachian’s triennial-review application, the
    Commission found that “Appalachian has not established that it was reasonable to conclude in
    December 2019 that the remaining costs of these retired units were no longer probable of future
    recovery” for the purposes of recording them as asset impairments. 14 J.A. at 5914-15. The
    Commission also rejected Appalachian’s argument that the Commission had no discretion to
    review Appalachian’s decision to record the asset impairments. The Commission reasoned that
    8
    “[i]n every historical earnings review under [Code § 56-585.1], the Commission has necessarily
    been required to rule on the reasonableness of the utility’s regulatory accounting entries, along
    with other proposed regulatory adjustments from both the utility and case participants.” Id. at
    5914. After the Commission has determined the reasonableness of these entries and adjustments,
    Code § 56-585.1 dictates certain outcomes.
    The Commission also held that Appalachian had not met its burden to establish the
    reasonableness of its depreciation expenses during the triennial period for purposes of
    determining its reasonable earned return. The Commission instead found that its Staff’s revised
    2017 Depreciation Study represented reasonable depreciation expenses and implemented the
    revised depreciation rates as of December 31, 2017. The Commission also found that its Staff’s
    regulatory treatment of the retired units was reasonable and based upon sound professional
    judgment. The Staff’s recommendations included removing the retired units from the 2017
    Depreciation Study, implementing a 10-year straight-line amortization of their remaining costs
    from the date of their retirements, and converting the retired units into regulatory assets.
    The Commission rejected Appalachian’s argument that these findings unlawfully change
    base rates for prior rate periods when rates were otherwise frozen. The Commission pointed out
    that this Court has affirmed the legality of the Commission’s consistent regulatory-accounting
    practice of establishing reasonable depreciation expenses and regulatory assets and has affirmed
    that such a practice does not constitute a retroactive change in rates. See 14 J.A. at 5918-19
    (citing Washington Gas Light Co. v. State Corp. Comm’n, Record No. 040878, 
    2004 WL 7331918
    , at *1 (Va. Oct. 8, 2004) (unpublished)). The Commission did not apply Code § 56-
    585.1(E), which was added to the statute in 2020, to these proceedings. The Commission held
    9
    that this amendment to the statute became effective after Appalachian filed its triennial-review
    application and did not expressly state that the amendment was to operate retroactively.
    Next, the Commission rejected Consumer Counsel’s position that Appalachian incurred
    expenses under the ICPA, which was approved in 2011, greater than comparable market prices
    and that as a result, Appalachian’s recognized triennial expenses should be decreased. The
    Commission found that Appalachian’s ICPA-energy costs were $49 million below comparable
    market-energy costs and that Appalachian’s ICPA-capacity costs could not be compared to
    market-capacity costs because the market-capacity costs proffered by Consumer Counsel for
    comparison purposes were for short-term capacity while the purchases under the ICPA were for
    long-term capacity.
    Finally, the Commission determined that Appalachian’s earned return was not more than
    70 basis points above or below 9.42%. Accordingly, customers would not receive a bill credit,
    nor would Appalachian be permitted to increase its rates. The Commission also determined that
    Appalachian’s ROE for the next triennial review should be reduced to 9.2%.
    Both Appalachian and Consumer Counsel filed petitions for reconsideration. The
    Commission granted reconsideration and suspended its final order. In its reconsideration order,
    the Commission clarified that it “did not perform a going-forward rate review” and “did not ‘set’
    or otherwise establish going-forward rates” based upon its determination of Appalachian’s
    reasonable rate of return in the triennial-review period. 14 J.A. at 6180. However, it confirmed
    that a fair ROE in the next triennial period “was any point within the range of 8.3% to 9.3% and
    chose 9.2% for this purpose.” Id. at 6180-81 n.6. Although the plain language of Code § 56-
    585.1 does not require a going-forward rate case in every historical earnings review, the
    Commission found no constitutional violations in denying a rate increase because the General
    10
    Assembly has provided other procedures by which a utility may challenge its rates. Specifically,
    Appalachian could apply for emergency rate relief under Code § 56-245 or a rate increase under
    Chapter 10 of Title 56 pursuant to the Commission’s rate-case rules. The Commission also
    found that Appalachian’s arguments on this point appeared to be barred under approbate-
    reprobate principles because, according to the Commission reading of the record, Appalachian
    had taken successive positions that were either inconsistent or mutually contradictory.
    Next, the Commission reconsidered its findings related to Appalachian’s 2015 retirement
    of certain coal-fired power plants. The Commission concluded that its findings continued to
    “represent a reasonable and rational exercise of [its] delegated discretion under [Code § 56-
    585.1].” 14 J.A. at 6184. The Commission found that Appalachian’s decision to impair these
    assets was not reasonable because Appalachian never established that these assets were “no
    longer probable of future recovery” before recording the asset impairments. Id. at 6187. No
    change in circumstances or triggering event had occurred in 2019 to cause these assets to be
    impaired, and they remained probable of future recovery as they had been since their retirement
    in 2015.
    The Commission rejected Appalachian’s argument that the statute removed the
    Commission’s regulatory discretion to review Appalachian’s decision to record these asset-
    impairment costs under Code § 56-585.1(A)(8). Under the Commission’s view, subsection D of
    the statute gives the Commission authority to challenge “the reasonableness or prudence of any
    cost incurred” by a utility. 14 J.A. at 6189. The Commission concluded that subsection A(8)
    “directs how the Commission must treat (i.e., deem fully recovered in the period recorded)
    certain costs” but “does not remove the Commission’s authority to determine the reasonableness
    of such costs in the first instance.” Id.
    11
    The Commission also rejected Consumer Counsel’s request to reduce the $88.3 million
    remaining net book values with Appalachian’s alleged overearnings from 2015 and 2016. The
    Commission determined that due to the transitional-rate period, Appalachian’s regulatory
    earnings during those years had not been audited or litigated, and thus, the Commission had
    never concluded that Appalachian had over-earned. Under those circumstances, forcing
    Appalachian to write off any of the $88.3 million in 2015 and 2016 was unreasonable.
    Finally, the Commission reconsidered its findings that ICPA-capacity costs should be
    allowed for purposes of determining Appalachian’s earned return during the triennial-review
    period. The Commission reiterated its prior findings that the market-capacity costs proffered by
    Consumer Counsel for comparison were based on “a single-year construct” with a pricing model
    using a “three-year delivery period,” while the ICPA-capacity costs were based on “a long-term
    baseload generation capacity asset that extends through 2040.” Id. at 6198. The Commission
    also emphasized that other evidence presented by Appalachian was sufficient to establish the
    reasonableness of the ICPA-capacity costs. See 6 id. at 2874-76 (comparing the 2011
    Benchmark Study to ICPA-capacity costs rather than Consumer Counsel’s proffered market-
    capacity costs). Both Appalachian and Consumer Counsel appealed.
    II. APPALACHIAN’S APPEAL
    On appeal, Appalachian’s 11 assignments of error can be distilled into the following
    issues:
    A. whether impairment costs related to Appalachian’s coal-fired
    power plants should have been deemed fully recovered in the
    triennial-review period in which they were recorded pursuant
    to Code § 56-585.1(A)(8),
    B. whether the Commission’s refusal to order an increase in rates
    or to analyze the sufficiency of going-forward rates constituted
    a constitutional taking, and
    12
    C. whether the Commission should have implemented the revised
    depreciation rates from Appalachian’s 2017 Depreciation
    Study.
    We will take up each of these issues in turn.
    A. Coal-Fired Plant Impairment Costs
    1.
    The first issue involves a debate over the textual and contextual meaning of various
    statutory provisions. Well-established principles guide our interpretative task. Virginia tradition
    has always been to ask “not what the legislature intended to enact, but what is the meaning of
    that which it did enact. We must determine the legislative intent by what the statute says and not
    by what we think it should have said.” Carter v. Nelms, 
    204 Va. 338
    , 346 (1963). We thus do
    not inquire as to “what the legislature meant; we ask only what the statute means.” Tvardek v.
    Powhatan Vill. Homeowners Ass’n, 
    291 Va. 269
    , 277 n.7 (2016) (quoting Oliver Wendell
    Holmes, The Theory of Legal Interpretation, 
    12 Harv. L. Rev. 417
    , 419 (1899)).
    Following this tradition, “[i]t is our duty to interpret the statute as written and when this
    is done our responsibility ceases.” City of Lynchburg v. Suttenfield, 
    177 Va. 212
    , 221 (1941);
    see also Continental Baking Co. v. City of Charlottesville, 
    202 Va. 798
    , 805 (1961). Because
    “[w]e can only administer the law as it is written,” Coalter v. Bargamin, 
    99 Va. 65
    , 71 (1901),
    the interpretative principle that precedes all others is that “courts must presume that a legislature
    says in a statute what it means and means in a statute what it says there,” Arlington Cent. Sch.
    Dist. Bd. of Educ. v. Murphy, 
    548 U.S. 291
    , 296 (2006) (citation omitted). 5
    5
    A literal reading of the statutory text, of course, should never “result in a manifest
    absurdity.” Butler v. Fairfax Cnty. Sch. Bd., 
    291 Va. 32
    , 37 (2015). That said, “the anti-
    absurdity principle — understood in its legal sense — serves only as an interpretative brake on
    irrational literalism. This fail-safe applies in situations in which a purely literal reading forces
    13
    In this case, as in most cases involving statutory interpretation, litigants argue the
    competing policy virtues of their proffered interpretations. In Virginia, however, judicial review
    does not evaluate “the propriety, wisdom, necessity and expediency of legislation.” Willis v.
    Mullett, 
    263 Va. 653
    , 658 (2002) (alteration omitted) (quoting City of Richmond v. Fary, 
    210 Va. 338
    , 346 (1969)). When a statutory text speaks clearly on a subject, “effect must be given to it
    regardless of what courts think of its wisdom or policy.” Temple v. City of Petersburg, 
    182 Va. 418
    , 423 (1944). Courts committed to neutral principles of interpretation “are not ‘free to pave
    over bumpy statutory texts in the name of more expeditiously advancing a policy goal.’”
    Southwest Airlines Co. v. Saxon, 
    142 S. Ct. 1783
    , 1792 (2022) (quoting New Prime Inc. v.
    Oliveira, 
    139 S. Ct. 532
    , 543 (2019)). Divinations of “the spirit or reason of the law,” Saville v.

    , 452 (1913), and “vague invocations of statutory
    purpose,” Southwest Airlines Co., 142 S. Ct. at 1792-93, cannot take precedence over a clearly
    worded statutory text.
    2.
    Working within this interpretative paradigm, we turn to the text of the governing statutes.
    The 2013 amendment to Code § 56-585.1(A)(8) permitted, inter alia, costs “associated with asset
    impairments related to early retirement determinations” that were “recorded per books by the
    utility for financial reporting purposes” to be “attributed to the test periods under review.” See
    2013 Acts ch. 2, at 7.6 In 2018, another amendment to subsection A(8) required these costs as
    the statutory text into an ‘internally inconsistent’ conflict or renders the statute ‘otherwise
    incapable of operation.’” Tvardek, 291 Va. at 280 (citation omitted).
    6
    When the phrase “associated with asset impairments related to early retirement
    determinations” was added to the statute in 2013, it was limited to early retirement decisions
    “made by the utility prior to December 31, 2012,” 2013 Acts ch. 2, at 7. In 2018, the phrase
    “prior to December 31, 2012” was deleted by the General Assembly. 2018 Acts ch. 296, at 513.
    14
    recorded to be “deemed fully recovered in the period recorded.” 2018 Acts ch. 296, at 513.
    When this statute was first enacted in 2007, a different subsection granted the Commission the
    general power to “determine, during any proceeding authorized or required by this section, the
    reasonableness or prudence of any cost incurred or projected to be incurred, by a utility in
    connection with the subject of the proceeding.” Code § 56-585.1(D). The combined text of the
    2013 and 2018 amendments to subsection A, however, uses very different language:
    In any triennial review proceeding, for the purposes of reviewing
    earnings on the utility’s rates for generation and distribution
    services, the following utility generation and distribution costs not
    proposed for recovery under any other subdivision of this
    subsection, as recorded per books by the utility for financial
    reporting purposes and accrued against income, shall be attributed
    to the test periods under review and deemed fully recovered in the
    period recorded: costs associated with asset impairments related
    to early retirement determinations made by the utility for utility
    generation facilities fueled by coal . . . .
    Code § 56-585.1(A)(8) (emphases added).
    Appalachian argues that the plain meaning of the 2013 and 2018 amendments applies
    specifically to this case. The syllogism is simple:
       The Commission was conducting a “triennial review
    proceeding.” Id.
       The costs were “recorded per books by the utility for financial
    reporting purposes” in compliance with governing financial-
    reporting standards. Id.
       Thus, the costs “shall be attributed to the test periods under
    review and deemed fully recovered in the period recorded.” Id.
    In response, the Commission argues that subsection D continues to grant the Commission
    regulatory discretion to determine on a case-by-case basis whether the shall-be command of
    subsection A(8) should be understood as a mere suggestion that the Commission has the
    discretion to either accept the recording and recovery of an asset-impairment cost as reasonable
    15
    or reject it as unreasonable. See, e.g., Comm’n Br. (Record No. 210391) at 16 (“[T]he General
    Assembly gave the Commission the authority to determine the reasonableness of any cost in
    connection with this proceeding, and there is no statutory exclusion for asset impairment costs.”).
    We believe traditional canons of statutory construction militate against this view.
    a.
    Statutory amendments are presumed to amend statutes — to change something that was
    there or to add something that was not there before. See Kerns v. Wells Fargo Bank, N.A., 
    296 Va. 146
    , 157 (2018) (“[W]hen current and prior versions of a statute are at issue, there is a
    presumption that the General Assembly, in amending a statute, intended to effect a substantive
    change in the law.” (citation omitted)); City of Richmond v. Sutherland, 
    114 Va. 688
    , 693 (1913)
    (“It must be presumed that the Legislature, in making the amendment, . . . intended by this added
    provision to make some change in the existing law.”). Sometimes that presumption does not
    work, such as when an amendment seeks only to clarify and confirm existing law. See Chappell
    v. Perkins, 
    266 Va. 413
    , 420 (2003) (“Legislation is presumed to effect a change in the law
    unless there is clear indication that the General Assembly intended that the legislation declare or
    explain existing law.”). But in the mine-run of cases, the presumption remains unrebutted. That
    is the case here.
    The 2007 enactment of subsection D in Code § 56-585.1 granted the Commission
    regulatory discretion to determine “the reasonableness or prudence” of a utility’s costs “incurred
    or projected to be incurred.” The parties debate whether this statutory grant of discretion extends
    to determining the time frame in which those costs are recoverable. We need not resolve this
    debate, however, because the 2013 and 2018 amendments to subsection A(8) took away any such
    regulatory discretion to determine the reasonableness of “costs associated with asset impairments
    16
    related to early retirement determinations” for coal-fired power plants that were “recorded per
    books by the utility for financial reporting purposes and accrued against income.” Code § 56-
    585.1(A)(8). 7 Those particular costs cannot be treated as a regulatory asset and amortized over
    whatever length of time the Commission deems to be reasonable or prudent. Instead, by statute,
    these costs “shall be attributed to the test periods under review and deemed fully recovered in the
    period recorded.” Id. The imperative “shall be” applies both to the timing of the attribution of
    costs as well as to the timing of the recovery of those costs.
    The 2013 amendment to subsection A(8) uses technical language found nowhere else in
    the Code of Virginia. There is no common, layperson meaning to the terms “asset impairments,”
    “recorded per books,” or “financial reporting purposes.” These are terms of art used in the
    administrative regulations governing corporate finances. Because Code § 56-585.1(A)(8)
    addresses a “technical subject” using words “obviously transplanted from another legal source,”
    Antonin Scalia & Bryan A. Garner, Reading Law: The Interpretation of Legal Texts 73 (2012)
    (quoting Felix Frankfurter, Some Reflections on the Reading of Statutes, 
    47 Colum. L. Rev. 527
    ,
    537 (1947)), we must “explain them by reference to the art or science to which they are
    appropriate.” Corning Glass Works v. Brennan, 
    417 U.S. 188
    , 201 (1974) (alteration omitted)
    7
    Our colleagues in dissent contend that costs governed by subsection A(8) are still
    subject to the Commission’s regulatory authority under subsection D because there is no express
    language in A(8) delineating such a limitation like there is in subsections A(4) and A(6) of the
    same statute. See post at 40. But under our view there is an obvious reason why the General
    Assembly thought it unnecessary to make such a proviso. By its plain terms, subsection A(8)
    wholly supplants the regulatory discretion authorized by subsection D because subsection A(8)
    only requires that the costs listed be “recorded per books by the utility for financial reporting
    purposes,” taking those costs entirely out of the realm of regulatory accounting for the purposes
    of recovery. Subsections A(4) and A(6), however, do not mention financial reporting and thus
    require an express statement to remove the costs governed by those subsections from the
    Commission’s regulatory discretion.
    17
    (quoting Greenleaf v. Goodrich, 
    101 U.S. 278
    , 284 (1880)). This canon of interpretation is an
    obvious and ancient linguistic tool. “[T]erms of art” and “technical terms,” Blackstone reminded
    his 18th-century audience, “must be taken according to the acceptation of the learned in each art,
    trade, and science.” 1 William Blackstone, Commentaries *60. This concept is particularly
    pertinent when a law — like any one of the plethora of modern statutes — “regulates a particular
    trade, industry, or other narrowly defined sub-group.” James A. Heilpern, Dialects of Art: A
    Corpus-Based Approach to Technical Term of Art Determinations in Statutes, 
    58 Jurimetrics J. 377
    , 381 (2018).
    The term-of-art canon applies to this case. Code § 56-585.1(A)(8) speaks of costs
    “recorded per books by the utility for financial reporting purposes.” This expression has a highly
    refined legal meaning when applied to publicly traded companies incorporated in the United
    States. Under subsection A(8), the books of these companies “for financial reporting purposes”
    are governed by rules and regulations promulgated by the Securities and Exchange Commission
    (“SEC”) under authority granted by, inter alia, the Securities Act of 1933, the Securities and
    Exchange Act of 1934, the Sarbanes-Oxley Act of 2002, and the Dodd-Frank Wall Street Reform
    and Consumer Protection Act of 2010.8
    Among other things, these statutes and a host of federal rules and regulations empower
    the SEC to enforce the financial-reporting duties imposed upon publicly traded companies. One
    of the principal purposes of SEC oversight is to ensure that investors of publicly traded
    companies have accurate information from which to gauge the true worth of a company before

    deciding whether to buy, sell, or trade the company’s stock. 9 To lawfully report the financial
    state of a publicly traded company to the SEC, the company must use the legal definitions and
    required practices known as “generally accepted accounting principles,” or “GAAP.” See
    generally 15 U.S.C. § 78m(b)(2)(B)(ii) (requiring companies to “devise and maintain a system of
    internal accounting controls sufficient to provide reasonable assurances that . . . transactions are
    recorded as necessary (I) to permit preparation of financial statements in conformity with
    generally accepted accounting principles or any other criteria applicable to such statements, and
    (II) to maintain accountability for assets”). The SEC presumes that financial statements “not
    prepared in accordance with [GAAP]” are “misleading or inaccurate.”

    Under GAAP, an asset impairment is simply “the condition that exists when the carrying
    amount of a long-lived asset (asset group) exceeds its fair value.” FASB ASC 360-10-20. An
    “impairment loss” exists when
    the carrying amount of a long-lived asset (asset group) is not
    recoverable and exceeds its fair value. The carrying amount of a
    long-lived asset (asset group) is not recoverable if it exceeds the
    sum of the undiscounted cash flows expected to result from the use
    and eventual disposition of the asset (asset group). That
    assessment shall be based on the carrying amount of the asset
    (asset group) at the date it is tested for recoverability, whether in
    use or under development. An impairment loss shall be measured
    as the amount by which the carrying amount of a long-lived asset
    (asset group) exceeds its fair value.
    FASB ASC 360-10-35-17 (emphasis added) (citations omitted). An asset is tested for
    “recoverability” when there are “events or changes in circumstances,” FASB ASC 360-10-35-21,
    that could affect the “undiscounted cash flows expected to result from the use and eventual
    disposition of the asset,” FASB ASC 360-10-35-17. The FASB ASC provides a list of example
    “events or changes in circumstances,” including “[a] significant adverse change in legal factors
    or in the business climate that could affect the value of a long-lived asset (asset group), including
    an adverse action or assessment by a regulator,” FASB ASC 360-10-35-21, but “the list of events

    and circumstances . . . is not intended to be all-inclusive,” Joanne M. Flood, Wiley Practitioner’s
    Guide to GAAP 2022: Interpretation and Application of Generally Accepted Accounting
    Principles 425 (2022).
    No GAAP definition related to impairment expressly states or reasonably implies that
    cash flows are to be considered from the use and eventual disposition of other assets or other
    asset groups not deemed to be impaired. In fact, the asset-impairment section of the FASB ASC
    states the exact opposite. See FASB ASC 360-10-35-29 (“Estimates of future cash flows used to
    test the recoverability of a long-lived asset (asset group) shall include only the future cash
    flows . . . that are directly associated with and that are expected to arise as a direct result of the
    use and eventual disposition of the asset (asset group).”). See generally Flood, supra, at 426-27.
    Income from sources other than the impaired assets are legally irrelevant to the question whether
    an asset should be deemed an unrecoverable loss and thus impaired for financial reporting
    purposes. To be sure, the point of the impairment-loss concept is to require companies to admit
    the obvious — that an asset should be considered a loss because the asset’s carrying amount will
    not exceed the “cash flows” that would result from the continued “use” of the asset and its
    “eventual disposition.” See FASB ASC 360-10-35-17. To not record the asset impairment
    properly would violate GAAP and mislead investors, lenders, suppliers, and customers. 11

    (recognizing the standard for inferring scienter is “whether the need to write-down the asset was
    ‘so apparent’ to the defendant before the announcement [of financial statements] that a failure to

    b.
    In this case, independent public auditors verified Appalachian’s reporting of the impaired
    assets. Consistent with GAAP standards and relevant federal laws, rules, and regulations, the
    auditors “perform[ed] procedures to assess the risks of material misstatement of the consolidated
    financial statements, whether due to error or fraud, and perform[ed] procedures that respond to
    those risks.” 6 J.A. at 2929. “Such procedures included examining, on a test basis, evidence
    regarding the amounts and disclosures” in Appalachian’s financial statements and “evaluating
    the accounting principles used and significant estimates made by management, as well as
    evaluating the overall presentation of the consolidated financial statements.” Id. The auditors
    confirmed that Appalachian’s books, including its entries for asset-impairment costs, were in
    conformity with GAAP.
    Faced with this uncontradicted evidence, Commission Staff admitted that Appalachian
    properly recorded the asset impairment costs during the triennial-review period “[f]or financial
    reporting purposes,” 10 id. at 4240, and that the Staff was “not questioning the Company’s
    accounting or attempting to force the Company to account for costs in a specific way under
    GAAP,” 13 id. at 5660. Thus, from the perspective of investors and the public at large, the costs
    were properly recorded on the company’s books for financial reporting purposes consistent with
    GAAP.
    This background is necessary because the 2013 and 2018 amendments to Code § 56-
    585.1(A)(8) are unlike any other statutory provision governing the Commission’s regulatory
    authority. These amendments took away the Commission’s regulatory discretion to override
    GAAP-compliant, asset-impairment costs “not proposed for recovery under any other
    subdivision of this subsection.” Code § 56-585.1(A)(8). The plain language of the 2013 and
    22
    2018 amendments makes clear that asset-impairment costs “shall be attributed to the test periods
    under review and deemed fully recovered in the period recorded.” Id. Prior to these
    amendments, this would not have been the case. A utility could comply with GAAP in recording
    asset-impairment costs and yet still have those costs deferred beyond the present review period
    by the Commission. The 2013 and 2018 amendments to subsection A(8) changed, not clarified,
    existing law by expressly limiting the Commission’s broad scope of regulatory discretion under
    subsection D. Cf. Appalachian Power Co. v. State Corp. Comm’n, 
    284 Va. 695
    , 706 (2012)
    (holding that the use of “shall” in the statute governing the approval of a rate-adjustment petition
    “clearly states the intent of the legislature” and precluded the Commission from denying
    recovery for certain incurred costs, which the Commission had deemed would produce unjust
    and unreasonable rates).
    What is true generally is true here: Where a statute includes a general provision with
    broad terms and a specific provision with narrow terms, the latter qualifies the former. See
    Chesapeake Hosp. Auth. v. State Health Comm’r, ___ Va. ___, ___, 
    872 S.E.2d 440
    , 447 (2022)
    (“Under the rules of statutory construction, when one statute speaks generally on an issue and
    another addresses the same issue in a more specific manner, ‘the two should be harmonized, if
    possible, and where they conflict, the latter prevails.’” (citation omitted)); Scalia & Garner,
    supra, at 183 (stating that “[i]f there is a conflict between a general provision and a specific
    provision, the specific provision prevails”). The Commission erred in concluding otherwise.
    3.
    On brief and during oral argument, the Commission argued that our reasoning misses a
    crucial point — that the Commission made a factual finding that the assets (the early retired coal-
    fired power plants) were not impaired, Comm’n Br. (Record No. 210391) at 15-22, because the
    23
    costs associated with retiring these assets could be “recovered” through Appalachian’s aggregate
    future rate income. See Oral Argument Audio (Record No. 210391) at 39:00 to 39:32. We take
    this claim seriously given our respect for the Commission’s role in determining disputed facts
    and our deference to its factfinding. See Wal-Mart Stores E., LP v. State Corp. Comm’n, 
    299 Va. 57
    , 75 (2020); City of Alexandria v. State Corp. Comm’n, 
    296 Va. 79
    , 93-94 (2018). Even so,
    just as we do not allow litigants to camouflage legal conclusions as factual assertions, Doe ex rel.
    Doe v. Baker, 
    299 Va. 628
    , 641 (2021), we do not defer to factual findings based upon faulty
    legal definitions, Virginia Elec. & Power Co. v. State Corp. Comm’n, 
    284 Va. 726
    , 736 (2012)
    (“[T]he Commission’s decision, if based upon a mistake of law, will be reversed.”). The
    Commission’s assertion that the coal-fired power plants are not factually “impaired assets”
    makes two legal assumptions that we reject.
    First, the Commission assumes that if Appalachian can successfully amortize the total
    costs in the future as a regulatory asset under approved rates, those costs are “probable of future
    recovery,” Oral Argument Audio (Record No. 210391) at 39:13 to 39:47, and thus, by definition
    cannot be an impairment loss. This assumption relies on the Commission exercising broad
    discretion under Code § 56-585.1(D) and applying regulatory accounting principles pursuant to
    that discretion. The 2013 and 2018 amendments to subsection A(8), however, changed the law
    and removed the Commission’s regulatory discretion for certain categories of costs, including
    asset-impairment costs related to early retirement determinations made by the utility for coal-
    fired power plants. See supra at 22-23. If the amendments to subsection A(8) did not change the
    law regarding the Commission’s regulatory discretion for these costs, those amendments were
    meaningless because subsection D has been in Code § 56-585.1 since its inception. See 2007
    Acts ch. 888, at 2418. Appalachian has argued to both the SCC below and to us on appeal that
    24
    amended subsection A(8) “does not permit the Commission to decide that a disagreement with
    an impairment ‘on a regulatory accounting basis’ can impact whether the impairment is recorded
    ‘for financial reporting purposes.’” 14 J.A. at 6014-15 (citation omitted); see also Appalachian
    Br. (Record No. 210391) at 18-23; Reply Br. (Record No. 210391) at 1-6. We agree.
    Regulatory accounting under FASB ASC Topic 980 allows a regulated entity to record a
    regulatory asset for the purpose of deferring costs “even though a nonregulated enterprise would
    be required to expense these costs currently” under financial accounting principles. Flood,
    supra, at 1300; see also FASB ASC 980-340-25-1 (recognition of regulatory assets). But
    amended subsection A(8) requires only that these asset-impairment costs, “as recorded per books
    by the utility for financial reporting purposes and accrued against income, shall be attributed to
    the test periods under review and deemed fully recovered in the period recorded.” Under the
    governing legal standard for financial accounting purposes, an “impairment loss . . . is not
    recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use
    and eventual disposition of the asset (asset group).” FASB ASC 360-10-35-17 (emphasis
    added). The “use and eventual disposition of the asset” refers to the impaired asset, id., not the
    company’s remaining, unimpaired assets. Appalachian properly recorded these asset-impairment
    costs for financial reporting purposes as conceded by the Commission’s Staff and confirmed by
    Appalachian’s auditors. See supra at 20-22. From a pure financial accounting perspective,
    which is all that is required under amended subsection A(8), distinguishing impaired assets
    (which cannot financially save themselves) from unimpaired assets (which eventually can) is the
    very reason for the definition of impairment loss.
    Second, the Commission’s non-impairment factual finding presupposes that, as a matter
    of law, a determination of an impairment loss can only be made simultaneously with the early
    25
    retirement of an asset. See 14 J.A. at 6185 (noting that Appalachian decided in 2011 to early
    retire the assets and retired the assets in 2015 but that Appalachian “did not conclude that the
    units were impaired when retired” and “continued to conclude that the Retired Units were not
    impaired . . . until December 2019”). This conclusion, the Commission Staff argued below,
    follows from the statutory requirement that the asset impairments be “related to early retirement
    determinations,” Code § 56-585.1(A)(8). See 5 J.A. at 2295; 10 id. at 4165-76, 4240-43. Upon
    this assumption, the Commission summarily rejected Appalachian’s asset-impairment
    determination in 2019 because it could have been — and necessarily should have been — made
    in 2015 when the coal-fired power plants, or portions thereof, were retired early from service.
    See 14 id. at 6187 (“[A]t the time Appalachian recorded such [asset-impairment] cost, there had
    been no change or triggering event causing an impairment; i.e., the Retired Units were still
    probable of future recovery, just as they had been since 2015.”).
    We find no merit in the Commission’s conflation of early retired assets and impaired
    assets. An asset can be retired from service early and never become impaired, and an impaired
    asset can easily be “related” to a prior early retirement, Code § 56-585.1(A)(8). Nothing in the
    statute requires these distinct actions to be contemporaneous. The “related” modifier means to
    be “[c]onnected in some way” or to have a “relationship to or with something else.” Black’s
    Law Dictionary 1541 (11th ed. 2019). It has a broader meaning than simultaneous or
    contemporaneous. 12
    12
    Cf. Celotex Corp. v. Edwards, 
    514 U.S. 300
    , 307-08 (1995) (recognizing that “related
    to” in a statute is a “choice of words” that “suggests a grant of some breadth”); Shaw v. Delta Air
    Lines, Inc., 
    463 U.S. 85
    , 96-97 (1983) (concluding that “[a] law ‘relates to’ an employee benefit
    plan, in the normal sense of the phrase, if it has a connection with or reference to such a plan”);

    242 Va. 337

    clause covering claims ‘relating to’ a contract is broader than a clause covering claims ‘arising
    26
    The narrative of this case illustrates the relationship between the 2019 asset-impairment
    determination and the prior 2015 early retirement. In 2015, when Appalachian retired some of
    its coal-fired power plants, and portions thereof, the remaining net book value of these units for
    Virginia jurisdictional purposes was $88.3 million. Appalachian recorded this same $88.3
    million amount as an asset-impairment cost in 2019. The $88.3 million is “related” or
    “connected” because it would not have existed without Appalachian’s decision to early retire
    these units. This broad relationship is all that is required by Code § 56-585.1(A)(8).
    In Appalachian’s last review in 2014, Appalachian submitted a depreciation study that
    included proposed depreciation rates for the units that it anticipated retiring in 2015, but the
    Commission denied Appalachian’s request to change depreciation rates at that time due to
    uncertainty of upcoming EPA regulation and the effect that it would have on coal-fired power
    plants, see In re Appalachian Power Co., 
    2014 WL 6851256
    , at *28. The Commission instead
    directed that the depreciation rates be revisited at the next review scheduled for 2016. See 
    id.
    That review, however, never happened because the General Assembly enacted legislation
    canceling the 2016 review. See supra note 2. While Appalachian submitted a new depreciation
    study in 2017 at the Commission’s direction, a 2018 letter from the Commission regarding the
    study expressed “concerns about the Company’s proposal to depreciate the undepreciated
    balance of the 2015 retirements” and recommended that Appalachian “address its proposed
    accounting and ratemaking treatment of the 2015 Retirements in the Company’s next triennial
    review,” which was then scheduled for 2020. 6 J.A. at 2436.169. In 2018, the General
    Assembly also amended Code § 56-585.1(A)(8), directing that asset-impairment costs related to
    early retirement determinations “for the purposes of reviewing earnings on the utility’s rates for
    out of’ a contract” (citation omitted)).
    27
    generation and distribution services” should be “deemed fully recovered in the period recorded.”
    2018 Acts ch. 296, at 513.
    As Appalachian explained, this series of events “constitute[d] a change in circumstances”
    that permitted Appalachian to record the $88.3 million net book value of its retired assets as an
    asset impairment because applicable GAAP standards were satisfied under newly amended
    subsection A(8). See 6 J.A. at 2944; 13 id. at 5498. 13 This decision by Appalachian to record
    the asset-impairment costs in 2019 was confirmed by an independent auditor as complying with
    GAAP. 6 id. at 2929. Because the 2013 and 2018 amendments to Code § 56-585.1(A)(8) have
    removed the Commission’s discretion to alter the recovery of these costs that were recorded on
    the books for financial reporting purposes, the Commission’s factfinding on this issue is based
    on mistakes of law and must be reversed. 14
    13
    Given our holding, it is unnecessary to address Appalachian’s argument that even
    under the Commission’s theory of probable future recovery under regulatory accounting, the
    Commission’s 10-year amortization plan that begins in 2015 does not make the entire $88.3
    million probable of future recovery. First, Appalachian argues that the amortized costs covering
    2015 and 2016 will never be recovered because those years were outside the triennial-review
    period. See Oral Argument Audio (Record No. 210391) at 46:22 to 46:52. Second, the
    amortized costs distributed from 2017-2019 during the triennial-review period will never be
    recovered in the future because rates are only adjusted in a going-forward rate case in a triennial
    review and rates are not adjusted retroactively. See id. at 46:53 to 47:13. Under Appalachian’s
    view, while half of the $88.3 million may be probable of “recovery” in the future under the
    Commission’s amortization plan, not all of it will be recovered because half of that amount will
    have already been distributed to previous years not covered by future rate changes.
    14
    Nothing in this opinion should be read to contradict the remainder of Code § 56-
    585.1(A)(8), including the provision that the Commission “shall . . . authorize deferred recovery
    of such costs” that “fall more than 70 basis points below the fair combined rate of return” and
    “allow the utility to amortize and recover such deferred costs over future periods as determined
    by the Commission.”
    28
    B. Constitutional Taking
    In the alternative, Appalachian argues that the Commission’s refusal to order an increase
    in rates or to analyze the sufficiency of going-forward rates constituted a constitutional taking.
    Given our holding that the Commission erred in finding that the asset-impairment costs were
    unreasonable, we need not address this alternative argument as it is now moot. See
    Commonwealth v. White, 
    293 Va. 411
    , 419 (2017) (reaffirming that “[t]he doctrine of judicial
    restraint dictates that we decide cases ‘on the best and narrowest grounds available’”).
    C. Depreciation Rates
    Finally, Appalachian argues that the Commission erred in implementing depreciation
    rates from a revised 2017 Depreciation Study for the years 2018 and 2019. “[T]he standard of
    review applied to a Commission decision ‘will depend on the nature of the decision under
    review.’” City of Alexandria, 296 Va. at 93 (citation omitted). While we are “not inextricably
    bound” by and “will not hesitate to reverse” a Commission’s decision that “is based on a mistake
    of law,” the Commission’s findings of facts are reviewed under a different paradigm. Id. at 93-
    94 (citation omitted).
    “The Commission is charged with the responsibility of finding the facts and making a
    judgment,” and “[t]his [C]ourt is neither at liberty to substitute its judgment in matters within the
    province of the Commission nor to overrule the Commission’s finding of fact unless we can say
    its determination is contrary to the evidence or without evidence to support it.” Board of
    Supervisors of Campbell Cnty. v. Appalachian Power Co., 
    216 Va. 93
    , 105 (1975). “In this
    context, we only ask whether a rational factfinder could have interpreted the historical facts,
    accompanied by reasonable inferences therefrom, in a way supportive of and consistent with the
    SCC’s conclusions.” City of Alexandria, 296 Va. at 94. This highly deferential standard exists
    29
    because the Commission “is exercising a legislative function delegated to it by the General
    Assembly” when exercising its ratemaking authority. Id. (citations omitted). “We thus ‘presume
    that where the General Assembly has not placed an express limitation in a statutory grant of
    authority, it intended for the Commission, as an expert body, to exercise sound discretion.’” Id.
    (citation omitted).
    The Commission ordered at Appalachian’s last review in 2014 that “depreciation rates
    should not be changed at this time” and that the issue would be revisited at the “next biennial
    review.” In re Appalachian Power Co., 
    2014 WL 6851256
    , at *28. Because the General
    Assembly canceled the 2016 biennial review, Appalachian contends that the language in the
    Commission’s 2014 order means that “any changes to [Appalachian’s] depreciation rates were
    delayed until this proceeding” 15 and that the Commission erred in “disregard[ing] its 2014 Final
    Order” and implementing depreciation rates from the revised 2017 Depreciation Study for 2018
    and 2019. Appalachian Br. (Record No. 210391) at 36, 38-39. The Commission, however, did
    not err in finding that Appalachian’s depreciation rates were unreasonable.
    To begin, Appalachian has the “burden to show that the expenses it seeks to have
    included in its rate base are just and reasonable,” Hopewell Cogeneration Ltd. P’ship v. State
    Corp. Comm’n, 
    249 Va. 107
    , 115 (1995) (citing Code § 56-235.3), and Appalachian has failed to
    do so. Appalachian’s sole argument on appeal is that the Commission is bound by the
    15
    This contention that the depreciation-rate change was delayed because of the rate
    freeze put in place by the General Assembly when it canceled the 2016 biennial review fails to
    recognize “the distinction between the ‘rates’ which are allowed to be charged by an electric
    utility as determined by the Commission for a biennial period, and the ‘ROE’ set in the same
    biennial review process.” Virginia Elec. & Power Co., 284 Va. at 736. Just because the General
    Assembly froze the rates that Appalachian was allowed to charge does not mean that the
    depreciation rates that help determine Appalachian’s ROE were also necessarily frozen during
    this period.
    30
    depreciation rates previously approved by the Commission in 2012 because the Commission’s
    2014 order did not change the rates at that time and stated that it would revisit the issue at the
    next review. But nothing in the Commission’s 2014 order alters Appalachian’s burden to show
    that the depreciation expenses it sought to include in its rate base were reasonable. Nor does any
    language in the Commission’s 2014 order take away the Commission’s discretion to review the
    reasonableness of Appalachian’s depreciation expenses as part of the present triennial-review
    proceeding. And no statutory provision expressly limits the Commission’s authority to review
    the reasonableness of Appalachian’s depreciation expenses in this scenario. For these reasons,
    we presume that the General Assembly “intended for the Commission, as an expert body, to
    exercise sound discretion” in determining reasonable depreciation rates for Appalachian, City of
    Alexandria, 296 Va. at 94.
    Appalachian was carrying a significant depreciation-reserve deficiency during the
    triennial period under review and did not request a change in depreciation rates to address that
    deficiency. Instead, the Commission’s Staff in 2017 requested that Appalachian submit a new
    depreciation study when the Staff realized that Appalachian was still using rates implemented
    from a 2010 depreciation study despite the Commission’s expectation that depreciation studies
    should be submitted at least every five years. See 12 J.A. at 5178. In this triennial-review
    proceeding, the Commission in its sound discretion implemented the depreciation rates from the
    revised 2017 Depreciation Study for the years 2018 and 2019. Because a rational factfinder
    could have interpreted these facts as supportive of the Commission’s conclusion that
    Appalachian’s depreciation rates were not reasonable due to its significant depreciation-reserve
    deficiency, we cannot overrule the Commission’s findings on this issue.
    31
    III. CONSUMER COUNSEL’S APPEAL
    In its cross-appeal, Consumer Counsel contends that the Commission’s final order erred
    in three ways:
    A. the Commission failed to apply Code § 56-585.1(E)
    retroactively;
    B. the Commission should not have established a regulatory asset
    for the early retirement costs of the coal-fired power plants,
    which would be amortized over ten years, but instead should
    have deemed those costs to be recovered by Appalachian’s
    overearnings in 2015 and 2016; and
    C. the Commission should not have found Appalachian’s
    evidence sufficient to demonstrate that its ICPA costs were
    lower than market costs.
    We will address each of these issues in turn.
    A. Retroactive Application of Code § 56-585.1(E)
    In the 2020 regular session, the General Assembly passed House Bill 528, adding
    subsection E to Code § 56-585.1. See 2020 Acts ch. 662, at 994. Code § 56-585.1(E) provides:
    “Notwithstanding any other provision of law, the Commission shall determine the amortization
    period for recovery of any appropriate costs due to the early retirement of any electric generation
    facilities owned or operated by any Phase I Utility or Phase II Utility.” The new subsection
    further lays out certain factors that the Commission shall consider in making that determination.
    Appalachian filed its triennial-review application on March 31, 2020, and subsection E became
    effective on July 1, 2020. We have previously recognized that “when a statute is amended while
    an action is pending, the rights of the parties are to be decided in accordance with the law in
    effect when the action was begun, unless the amended statute shows a clear intention to vary
    such rights.” Washington v. Commonwealth, 
    216 Va. 185
    , 193 (1975).
    32
    “It has long been the law of the Commonwealth that retroactive application of statutes is
    disfavored and that ‘statutes are to be construed to operate prospectively only unless a contrary
    intention is manifest and plain.’” City of Charlottesville v. Payne, 
    299 Va. 515
    , 528 (2021)
    (citation omitted). “Absent an express manifestation of intent by the legislature, this Court will
    not infer the intent that a statute is to be applied retroactively.” 
    Id.
     (citation omitted). Chief
    Justice Marshall long ago advised that “a court . . . ought to struggle hard against a [statutory]
    construction which will, by a retrospective operation, affect the rights of parties.” United States
    v. Schooner Peggy, 5 U.S. (1 Cranch) 103, 110 (1801). “The inquiry into whether a statute
    operates retroactively demands a commonsense, functional judgment about ‘whether the new
    provision attaches new legal consequences to events completed before its enactment.’” Martin v.
    Hadix, 
    527 U.S. 343
    , 357-58 (1999) (citation omitted).
    On appeal, Consumer Counsel contends that subsection E should be interpreted to apply
    retroactively to Appalachian’s triennial-review application because it “contains clear language
    showing retrospective legislative intent.” Consumer Couns. Br. (Record No. 210634) at 17. We
    disagree. Nothing in the language of subsection E makes it manifest and plain that the General
    Assembly intended for the subsection to apply retroactively.
    In support of its argument, Consumer Counsel focuses heavily on one word in subsection
    E and one opinion among the dozens of our opinions addressing the retroactivity doctrine. The
    word is “any,” which was used twice in the new subsection: “any appropriate costs” and “any
    electric generation facilities owned or operated.” Code § 56-585.1(E). As the sole authority for
    the claim that “any” indicates retroactive intent, Consumer Counsel cites Sussex Community
    Services Ass’n v. Virginia Society for Mentally Retarded Children, Inc., 
    251 Va. 240
     (1996). In
    that 4-3 opinion, the majority held that the language “any restrictive covenant” in a statutory
    33
    amendment governing the construction of certain types of restrictive covenants should be
    interpreted to apply retroactively and encompassed the construction of all restrictive covenants of
    that type “whether recorded before or after” the enactment of the amendment. Sussex, 251 Va. at
    244-45. In his dissent, Chief Justice Carrico stated that retroactive intent should not be so easily
    inferred from the sole use of the word “any” and that a broader perspective confirmed that the
    General Assembly was not attempting to apply the statute retroactively. Id. at 245-46 (Carrico,
    J., dissenting).
    The Commission in the present case summarily rejected Consumer Counsel’s argument
    that relied upon Sussex. We reject it as well. In Sussex, the statutory amendment in question
    was being applied prospectively by the majority to an event that would occur, if at all, after the
    amendment’s enactment — the alleged breach of a restrictive covenant — not retroactively to the
    recording of that restrictive covenant, an event “completed before its enactment,” Martin, 
    527 U.S. at 357-58
    . This before-and-after distinction is critical for understanding why the factual
    context and legal reasoning of Sussex are inapplicable here.
    The United States Supreme Court emphasized this distinction in Union Dry Goods Co. v.
    Georgia Public Service Corp., a case in which a state had mandated a rate increase for sales of
    electricity that became effective in the second year of a five-year sales contract between a
    supplier and buyer of electricity. See 
    248 U.S. 372
    , 373 (1919). The Supreme Court held that
    the legally prescribed rate prospectively applied to all sales of electricity after the effective date
    of the rate increase but not to the sales of electricity that had already occurred. See 
    id. at 375-77
    .
    It did not matter that the parties before the court still had three more years left on their contract
    subject to the lower price.
    34
    By analogy, the same was true in Sussex. It did not matter that the restrictive covenant
    had been recorded many years prior to the statutory amendment and continued to run with the
    land because the statutory amendment only applied prospectively to the interpretation of whether
    the restrictive covenant had been breached after the amendment’s enactment. While the ratio
    decidendi of Sussex was reasonably debatable, the result was clearly correct because the new
    statutory amendment applied to the interpretation of the restrictive covenant sought to be
    enforced after the amendment’s enactment and declared that the covenant should be construed to
    include the proposed use of the property. For this reason, the Commission correctly rejected
    Consumer Counsel’s interpretation and application of Sussex to this case.
    The Commission also rejected Consumer Counsel’s argument that the phrase
    “[n]otwithstanding any other provision of law” in Code § 56-585.1(E) “bolsters retrospective
    intent,” Consumer Couns. Br. (Record No. 210634) at 19. This language does not make
    subsection E retroactive. The non obstante phrase merely means that when subsection E does
    apply (the presumption is that it applies prospectively only) it takes precedence over any other
    conflicting provision of law. See generally Scalia & Garner, supra, at 126-27.
    Beyond the absence of a manifest and plain intention for subsection E to be applied
    retroactively in the text of subsection E, another bill amending Code § 56-585.1 in the same 2020
    General Assembly session demonstrates that the General Assembly did not intend for the new
    subsection E to be applied retroactively. Senate Bill 731 added an additional requirement for the
    Commission’s determination of the company’s fair rate of ROE, effective July 1, 2020, but also
    included the language in two different subsections that this additional requirement should apply
    to “applications received by the Commission on or after January 1, 2020,” 2020 Acts ch. 1108, at
    35
    2120 (codified as amended at Code § 56-585.1(A)(2)(a)-(b)). This language indicated a manifest
    and plain retroactive application of the new statutory language.
    As we have previously stated, “in enacting other amendments to the Act, the General
    Assembly employed language plainly manifesting a retroactive intent,” and “failure to use
    language of this nature” in another amendment to the same statute demonstrates that it was “not
    intended to be applied retroactively,” Berner v. Mills, 
    265 Va. 408
    , 414 (2003). In other words,
    “the General Assembly knows how to make its intent manifest that a statute has retroactive
    application,” City of Charlottesville, 299 Va. at 531. In this case, there is no textual support that
    the General Assembly intended for subsection E to be applied retroactively, and the contextual
    language of other amendments made to the same statute in the same General Assembly session
    demonstrates that subsection E was not intended to operate retroactively. 16 The Commission,
    therefore, did not err in summarily rejecting Consumer Counsel’s retroactivity argument.
    B. Recovery of Early Retirement Costs
    In its appeal, Consumer Counsel challenges both Appalachian’s recording of the early
    retirement costs of its coal-fired power plants as asset-impairment costs and the Commission’s
    ten-year amortization plan for the early retirement costs in its final order. Consumer Counsel
    instead argues that if the Commission had considered Appalachian’s overearnings from 2015 and
    2016, it would have found that the early retirement costs had already been recovered by
    Appalachian through revenues collected in 2015 and 2016. See Consumer Couns. Br. (Record
    16
    Given our holding that subsection E should not be applied retroactively, we need not
    address Consumer Counsel’s argument that retroactive application of subsection E does not
    disturb a vested or substantive right, see Consumer Couns. Br. (Record No. 210634) at 23-28, or
    Appalachian’s contention that subsection E does not apply at all to asset impairments and has no
    effect on subsection A(8), see Appalachian Br. (Record No. 210634) at 14-17.
    36
    No. 210634) at 28-38. Given our holding above that the Commission erred in finding that the
    asset-impairment costs were unreasonable, see supra at 28, we need not address Consumer
    Counsel’s argument as it is now moot. See White, 293 Va. at 419 (applying the best-and-
    narrowest doctrine).
    C. ICPA Costs
    Consumer Counsel’s final issue contends that the Commission erred in finding that
    Appalachian’s evidence was sufficient to demonstrate that its ICPA costs were lower than
    market costs. We see no merit in this contention.
    The Commission has the statutory authority “to scrutinize transactions between a utility
    and one of its affiliates” because “the contracting parties have a unity of interests and do not deal
    at arm’s length,” which presents “the opportunity for double profit at the ratepayers’ expense.”
    Commonwealth Gas Servs., Inc. v. Reynolds Metals Co., 
    236 Va. 362
    , 367 (1988). Appalachian
    bore the burden of proving the reasonableness of affiliate expenses under the ICPA. See 
    id. at 368
    . The question is whether Appalachian met this burden by submitting “satisfactory proof . . .
    to the Commission of the cost to the affiliated interest,” Code § 56-78. “No proof shall be
    satisfactory . . . unless it includes the original (or verified copies) of the relevant cost records and
    other relevant accounts of the affiliated interest . . . properly identified and duly authenticated.”
    Code § 56-79. In its 2011 order approving the ICPA, the Commission stated: “For cost recovery
    purposes during any rate proceeding, [Appalachian] bears the burden to prove that, for any
    purchases made from OVEC to serve [Appalachian’s] Virginia jurisdictional customers,
    [Appalachian] paid the lower of OVEC’s cost or the market price of non-affiliated power.” In re
    Appalachian Power Co., 
    2011 WL 3528704
    , at *2.
    37
    Sufficient evidence supports the Commission’s factual finding that Appalachian
    shouldered its burden of proof on this issue in the 2020 triennial-review proceeding.
    Appalachian presented a 2011 Benchmark Study that demonstrated the costs of a comparable
    alternative to the long-term capacity (extending through 2040) that Appalachian had purchased
    under the ICPA — a “new build base-load power plant,” 6 J.A. at 2874. Contesting this
    assertion, Consumer Counsel presented evidence of short-term, market-capacity costs that were
    based on a single-year construct with a three-year delivery period. The Commission stated in its
    reconsideration order that it had considered the evidence of both Appalachian and Consumer
    Counsel and found that “current market data does not exist to reasonably compare ICPA capacity
    costs.” 14 id. at 6198. The Commission further “found sufficient other evidence presented by
    [Appalachian] to establish the reasonableness of such costs for purposes of the triennial review.”
    Id.
    When the evidence does “little more than show that the parties’ experts disagreed,” this
    “does not render the Commission’s findings contrary to the evidence.” Wal-Mart Stores E., LP,
    299 Va. at 74 (citation omitted). “The Commission is entitled to interpret the conflicting
    evidence and to decide the weight to afford it.” Id. (citation omitted). “We cannot sit as a board
    of revision to substitute our judgment for that of matters within the province of the
    Commission.” City of Alexandria, 296 Va. at 103. We thus affirm the Commission’s findings
    on this issue. 17
    17
    Given our ruling, we offer no opinion on Appalachian’s argument that federal-
    preemption principles preclude the Commission from disallowing the ICPA costs. See
    Appalachian Br. (Record No. 210634) at 39-44.
    38
    IV. CONCLUSION
    In sum, we hold that (i) the Commission erred in finding that it was not reasonable for
    Appalachian to record its costs associated with the early retirement of its coal-fired power plants
    as asset impairments; (ii) the Commission did not err by implementing depreciation rates from
    the revised 2017 Depreciation Study for the years 2018 and 2019 in the triennial review; (iii) the
    Commission did not err by refusing to apply Code § 56-585.1(E) retroactively; and (iv) the
    Commission did not err in finding Appalachian’s affiliate costs under the ICPA to be reasonable.
    All remaining issues in both appeals are now moot. Accordingly, the Commission’s rulings are
    affirmed in part and reversed in part, and the matter is remanded for further proceedings
    consistent with this opinion.
    Affirmed in part,
    reversed in part,
    and remanded.
    SENIOR JUSTICE MIMS, with whom JUSTICE POWELL joins, dissenting in part.
    In section II.A.2 of the Court’s opinion, the majority holds that the 2013 and 2018
    amendments to Code § 56-585.1(A)(8) took away the Commission’s discretion to determine the
    reasonableness of “costs associated with asset impairments related to early retirement
    determinations” for coal-fired power plants that were “recorded per books by the utility for
    financial reporting purposes and accrued against income.” Code § 56-585.1(A)(8). According to
    the majority, once Appalachian recorded the asset impairment costs in its books, the Commission
    was required by Code § 56-585.1(A)(8) to attribute the asset impairment costs “to the test
    periods under review and deem them fully recovered in the period recorded.” Id. I disagree, and
    therefore respectfully dissent from this portion of the majority’s opinion.

    In determining that it had authority to review the reasonableness of Appalachian’s
    decision to record the asset impairment costs, the Commission relied on Code § 56-585.1(D),
    which states as follows:
    The Commission may determine, during any proceeding
    authorized or required by this section, the reasonableness or
    prudence of any cost incurred or projected to be incurred, by a
    utility in connection with the subject of the proceeding. A
    determination of the Commission regarding the reasonableness or
    prudence of any such cost shall be consistent with the
    Commission’s authority to determine the reasonableness or
    prudence of costs in proceedings pursuant to the provisions of
    Chapter 10 (§ 56-232 et seq.)
    The first sentence of subsection (D) is an extremely broad grant of authority by the
    General Assembly, authorizing the Commission to review “the reasonableness or prudence of
    any cost” incurred by a utility. The only time that authority is curtailed is in certain narrow
    instances where the General Assembly has specifically delineated such a limitation. For
    example, in Code § 56-585.1(A)(6), the General Assembly determined that certain costs
    associated with new underground facilities created to improve electric service reliability were “in
    the public interest” and therefore would be “deemed to be reasonable and prudently incurred and,
    notwithstanding the provisions of subsection C or D, shall be approved for recovery by the
    Commission.” Similarly, in Subsection (A)(4), the General Assembly carved out additional
    costs that would not be subject to a reasonableness inquiry in accordance with Subsection (D).
    Subsection (A)(4) states that certain costs incurred by the utility for transmission services,
    demand response programs approved by the Federal Energy Regulatory Commission, and
    providing service to a business park “shall be deemed reasonable and prudent.” Code § 56-
    585.1(A)(4).
    40
    Significantly, the General Assembly added the referenced specific exclusion from the
    effect of Subsection (D) to Subsection (A)(6) in 2018, during the same session that it amended
    Subsection (A)(8) to include the language that would deem the costs recorded per books by the
    utility “fully recovered in the period recorded.” 2018 Acts ch. 296. However, the General
    Assembly did not include a similar carve out from Subsection (D) in Subsection (A)(8).
    It is notable that in Section III.A of its opinion, when considering whether the General
    Assembly intended to apply amendments to Subsection (E) retroactively, the majority found it
    significant that during the same session, the General Assembly employed specific language to
    manifest its retroactive intent in to two different subsections. Because the General Assembly did
    not employ the same language in Subsection (E), the majority concludes that it did not intend
    Subsection (E) to operate retroactively. Similarly, because the General Assembly added a
    specific exclusion from Subsection (D) to Subsection (A)(6) in 2018 but did not include such an
    exclusion in Subsection (A)(8) during the same session, I conclude that asset impairment cost
    claims remain subject to review for “reasonableness and prudence” by the Commission.

    utilities.” Level 3 Commc’ns of Va., Inc. v. State Corp. Comm’n, 
    268 Va. 471
    , 474 (2004).
    Further, we “presume that where the General Assembly has not placed an express limitation in a
    statutory grant of authority, it is intended for the Commission, an expert body, to exercise sound
    discretion.” Virginia Elec. & Power Co. v. State Corp. Comm’n, 
    284 Va. 726
    , 741 (2012). This
    Court has repeatedly said that “[w]hen interpreting and applying a statute, we ‘assume that the
    General Assembly chose, with care, the words it used in enacting the statute, and we are bound
    by those words.’” Kiser v. A.W. Chesterton Co., 
    285 Va. 12

    , 100 (2001)); accord Rives v. Commonwealth, 284
    
    41 Va. 1
    , 3 (2012). Therefore, “‘when the General Assembly has used specific language in one
    instance, but omits that language or uses different language when addressing a similar subject
    elsewhere in the Code, we must presume that the difference in the choice of language was
    intentional.’”

    Because the General Assembly chose not to include a carve out from Subsection (D) in
    Subsection (A)(8), I believe it intended Subsection (D) and Subsection (A)(8) to be read
    together. See, e.g., Pro. Bldg. Maint. Corp. v. Sch. Bd. of Cty. of Spotsylvania, 
    283 Va. 747
    , 757
    (2012) (Mims, J., concurring) (observing that underlying statute within the Virginia Public
    Procurement Act and the 2000 amendment thereto “must [be] read . . . as an integrated whole”)
    (citing Alston v. Commonwealth, 
    274 Va. 759
    , 769 (2007) (statutes “should be so construed as to
    harmonize the general tenor or purport of the system and make the scheme consistent in all its
    parts and uniform in its operation, unless a different purpose is shown plainly or with irresistible
    clearness”)); Bowman v. Concepcion, 
    283 Va. 552
    , 563 (2012) (“[W]e will construe statutes that
    address the same general subject ‘so as to avoid repugnance and conflict between them and, if
    possible, to give force and effect to each of them.’”) (quoting City of Lynchburg v. English
    Constr. Co., 
    277 Va. 574
    , 584 (2009)). Under this construct, the Commission retains its
    authority to determine “the reasonableness or prudence of any cost incurred” by a utility in the
    categories listed under Subsection (A)(8). Accordingly, the Commission was acting within its
    authority when it considered whether it was reasonable for Appalachian to record $88.3 million
    in asset impairment costs in 2019.
    Asset impairment costs associated with the retired units was the most contentious issue
    before the Commission. It considered three different proposals regarding the $88.3 million asset
    42
    impairment cost. According to Appalachian, because it recorded the $88.3 million as an asset
    impairment cost in its books for financial reporting purposes, the full amount of this expense fell
    within the earnings review period, and Appalachian would be entitled to a rate increase.
    Consumer Counsel asserted that none of the $88.3 million should be considered an expense
    within the earnings review period, which likely would have led to a decrease in Appalachian’s
    rates. The third proposal, and the one the Commission found reasonable and approved, was put
    forth by Commission Staff and recommended the $88.3 million cost be amortized over ten years,
    starting in 2015 when the units were retired. This resulted in approximately 30% of the expense
    falling within the current earnings review period. I believe it was within the Commission’s
    broad discretion to determine that this proposal was the most reasonable way to allocate the asset
    impairment costs.
    The majority’s holding also takes away the Commission’s ability to protect rate payers
    from potentially unreasonable accounting practices that will result in rate increases. Now that
    Appalachian will be permitted to allocate all the asset impairment costs for the retired units in
    2019, Appalachian’s earnings for the triennial review period will be lowered to such an extent
    that the Commission will be required to conduct a going-forward rate case and Appalachian will
    be entitled to raise its rates. In its application, Appalachian stated that its proposed rate increases
    “are designed to effect an increase of approximately $65 million over current rates.” (JA 16).
    Appalachian acknowledged that under its proposal, on average, most rate payers would see a
    6.5% increase (JA 17). While other actions taken by the Commission might result in a slightly
    lower increase, there is no doubt that Appalachian’s accounting choices for this triennial review
    period, the reasonableness of which the Commission can no longer review, will result in a rate
    increase.
    43
    I believe the Commission properly exercised its authority under Code § 56-585.1(D)
    when it reviewed the reasonableness of Appalachian’s decision to record the asset impairment
    costs in 2019, and I would affirm the Commission’s ruling on this issue. I therefore respectfully
    dissent from Section II.A.2 of the majority’s opinion. I join the remainder of the opinion.
