    EASTERLY, Associate Judge: The Office of the People’s Counsel for the
    District of Columbia (“OPC”) brings this challenge to two orders of the D.C. Public
    Service Commission (“the Commission”) in Formal Case No. 1156, in which the
    Commission approved a multiyear rate plan for the Potomac Electric Power
    Company (“Pepco”)’s electricity distribution services from 2020 to 2022.
    Specifically, OPC argues that the Commission should not have permitted Pepco to
    recover costs from its distribution customers that it incurred in conducting a remedial
    investigation and feasibility study regarding possible environmental damage at or
    from its facilities at 3400 Benning Road NE, Washington, D.C. (“the Benning Road
    site”). OPC also contests the inclusion of two energy efficiency rebate and loan
    programs targeting small businesses in Pepco’s rate plan, which would permit Pepco
    to recover the costs of those programs from its customers in a future rate case.
    We vacate the Commission’s orders as to both issues and remand for further
    proceedings consistent with this opinion.
    3
    I.    OPC’s Challenge to Pepco’s Recovery of Remedial Investigation Costs
    A.     Facts and Procedural History
    Pepco’s Benning Road site is a 77-acre lot bordered by the Anacostia River
    on its western side. The site contains a service center used to support its transmission
    and distribution operations. The site also contains a power plant that began operating
    in or around 1906, consisting of structures including a generating station, cooling
    towers, and storage facilities. The generating station shut down in 2012.
    In 1999, attempting to step back from its then-active energy production
    business, Pepco applied to the Commission in Formal Case No. 945 for
    authorization to divest its generating assets according to its proposed plan. The D.C.
    Council, however, had “concerns”—the exact nature of which is not clear from the
    record—about the proposed sale of two generating stations, including the one at
    Benning Road, and thus it requested that the Commission hold the divestiture in
    abeyance. In order to move its divestiture application forward, and after engaging
    in “comprehensive negotiations,” Pepco agreed to comply with specific conditions
    regarding those stations. These conditions were memorialized in Section 1.05 of the
    resulting settlement agreement, hereinafter the “FCN 945 Settlement,” which
    provided:
    4
    Nothing in this Settlement Agreement shall be construed
    as requiring Pepco to include in the sale of the [generating
    a]ssets, the Company’s generating stations located at
    Benning Road and Buzzard Point in the District of
    Columbia; provided, however, that if the Benning Road
    and Buzzard Point generating stations are not included in
    the sale of the [generating a]ssets, the Company shall be
    thereafter barred and estopped from asserting or exercising
    any legal right that it might otherwise have to recover from
    customers located in the District of Columbia any stranded
    costs associated with those generating stations. In
    connection with any Pepco base rate proceeding in the
    District of Columbia instituted after June 30, 2000, the
    Benning Road and Buzzard Point generating stations shall
    not be included in the cost of service for purposes of
    determining the Company’s District of Columbia
    jurisdictional revenue requirement.
    The Commission approved this settlement agreement pursuant to its rules and
    procedures. See 15 D.C.M.R. § 130.13-.17 (2022).
    Ten years later, the United States Environmental Protection Agency (“EPA”)
    released a report detailing environmental toxins found on and around the Benning
    Road site. The report concluded that chemical contaminants known as PCBs 1 “have
    1
    “PCBs” refers to polychlorinated biphenyls, a solid waste that persists in the
    environment without degrading; if a person consumes fish or other organisms that
    have been contaminated with PCBs from their environment, the PCBs can cause “a
    variety of adverse health effects, including cancer.” Consent Decree at 2, District of
    Columbia v. Potomac Elec. Power Co., No. 1:11-cv-00282-BAH (D.D.C. Aug. 17,
    2011) [hereinafter “DOEE Consent Decree”], https://benningservicecenter.com/
    library/documents/BenningConsentDecree.pdf; https://perma.cc/WC6U-27WW.
    5
    been released from the site to the Anacostia River,” tracing one release of PCBs to
    “the generating station’s cooling tower basins,” which discharge into the river. It
    further concluded that “[t]he only potential uncontained potential source [of PCBs]
    identified on the site” was a sludge dewatering area previously used in association
    with the cooling towers.
    In response to the report, the District Department of Energy and Environment
    (“DOEE”) 2 notified Pepco that it intended to sue the company for abatement of
    hazardous conditions resulting from the Benning Road site. To settle the intended
    suit, Pepco entered into a consent decree in 2011 with the DOEE, which in part
    bound Pepco to conduct a remedial investigation and feasibility study (“RI/FS”) that
    would inform any future remedial actions. 3 As of the time of Pepco’s application in
    this case, the company’s work on the RI/FS was ongoing.
    In 2018, Pepco entered into a settlement agreement to resolve its 2017 rate
    application, Formal Case No. 1150, before the Commission (hereinafter the “FCN
    2
    At the time, the DOEE was known as the District Department of the
    Environment.
    3
    DOEE Consent Decree at 6.
    6
    1150 Settlement”).     OPC was also a party to the settlement.               Pepco had
    unsuccessfully sought to place its RI/FS costs in a “regulatory asset” in previous rate
    cases, but finally secured it in this settlement. 4 In relevant part, the FCN 1150
    Settlement provided:
    The Parties agree that Pepco will receive regulatory asset
    treatment in the total amount of $3.3 million in actual costs
    incurred to conduct a remedial investigation (“RI”) at the
    Benning facility. Pepco will begin to recover the $3.3
    million over a 10-year amortization period, with carrying
    costs based on the Company’s Commission-authorized
    rate of return. This recovery relates only to the RI costs
    that have already been incurred as a result of the [DOEE]
    Consent Decree . . . and does not relate to, or have any
    precedential effect on, the recovery of additional RI costs
    incurred as a result of the [DOEE] Consent Decree. . . .
    Notwithstanding the foregoing provision, the Parties agree
    that all Parties retain the right to challenge in future rate
    cases Pepco’s entitlement to any further recovery from
    ratepayers of this $3.3 million regulatory asset.
    The Commission approved this settlement pursuant to its rules and procedures. See
    15 D.C.M.R. § 130 (2022).
    4
    As the Commission explained at oral argument, a “regulatory asset” is a
    “tracking mechanism” that enables examination of which of the company’s costs
    were associated with a given item—here, the Benning Road RI/FS. As OPC
    explained in its reply brief, expenses recorded in a regulatory asset “are recognized
    as deferrals instead of period expenses” and are “deferred for potential future rate
    recovery.”
    7
    In 2019, Pepco applied to the Commission for authority to establish its
    distribution rates for 2020 to 2022 through a multiyear rate plan, initiating Formal
    Case No. 1156. A multiyear rate plan is an alternative form of regulation that permits
    the utility to avoid the traditional annual rate application process. In its application,
    Pepco requested that the Commission approve recovery of a portion of its amortized
    RI/FS costs that were included in the regulatory asset established in the FCN 1150
    Settlement. Specifically, Pepco asked for permission to include approximately $1.9
    million of its actual RI/FS costs incurred through December 31, 2017, in its
    calculation of the rates it would charge its distribution customers under the plan. It
    also requested similar recovery of its actual RI/FS costs incurred from January 1,
    2018, through June 30, 2019, approximately totaling an additional $3 million.
    The Commission received testimony and briefing from the various parties,
    including argument from OPC that Section 1.05 of the FCN 945 Settlement barred
    recovery of any RI/FS costs from the Benning Road site.              The Commission
    subsequently issued an order approving a modified version of Pepco’s multiyear rate
    plan that reflected some concessions to objections raised by OPC and others, but
    granted Pepco’s request to include in its rates the $1.9 million in pre-2018 RI/FS
    costs. After restating the relevant language from the FCN 1150 Settlement, the
    Commission noted that “[a] review of the Company’s request raises concerns about
    8
    the past uses of the site and how costs for the RI/FS . . . should be allocated among
    generation, transmission, and distribution, and ultimately the amount that should be
    recovered from District distribution customers.” But the Commission went on to
    conclude that it was “persuaded by Pepco that the [RI/FS] costs were prudently
    incurred and are recoverable consistent with Commission precedent.” Without
    further explanation or any reference to the FCN 945 Settlement, the Commission
    stated that it would permit the recovery “as the costs were approved in Formal Case
    No. 1150.” It then deferred Pepco’s related request for recovery of RI/FS costs
    “incurred after those approved in Formal Case No. 1150” (referring to the post-
    December 31, 2017, costs), to be considered in a future rate case “once the Benning
    Road environmental costs and future use of the property [are] determined.”
    OPC filed a request for reconsideration of the Commission’s order,
    challenging among other decisions the Commission’s approval of the RI/FS cost
    recovery from distribution customers. The Commission issued a second order
    declining to reconsider its initial order, but stating it would provide “clarification”
    of aspects of that order. In this clarifying order, the Commission engaged for the
    first time with OPC’s assertion that the FCN 945 Settlement barred recovery of the
    RI/FS costs captured in the regulatory asset. It stated that it was “not persuaded by
    OPC’s argument concerning the legal effect of [the FCN 945] Settlement
    9
    Agreement,” which “on its face . . . did not bar recovery of Pepco’s costs for future
    environmental remediation, only stranded costs and future operating costs.”
    Because in its view the “plain language” of the FCN 945 settlement agreement did
    not bar recovery, the Commission reaffirmed that it would allow recovery “because
    the costs were approved in Formal Case No. 1150.”
    This petition for review followed. 5
    5
    OPC filed two petitions for review, now consolidated: one of the initial
    order, filed after OPC requested reconsideration but before the Commission ruled
    on that request, and one of the subsequently issued clarifying order. The
    Commission asserts that this court lacks jurisdiction over the first petition because
    the initial order was not final at the time of filing, while OPC asserts that the
    Commission’s failure to grant or deny reconsideration within 30 days rendered its
    order final by statute. See 
    D.C. Code § 34-604
    (b). The Commission had instead
    issued a series of orders “tolling” its time to act on the request.
    We need not decide whether the Commission, by its own orders, had the
    power to toll the 30-day deadline under 
    D.C. Code § 34-604
    (b) to grant or deny
    reconsideration of its initial order. Even assuming that OPC’s first petition was
    technically premature when filed, we have jurisdiction over both its petition for
    review of the Commission’s initial order and its petition for review of the
    Commission’s clarifying order because the former was final by the time this case
    was submitted for our consideration. See West v. Morris, 
    711 A.2d 1269
    , 1271 (D.C.
    1998).
    10
    B.    Analysis
    The Commission did not engage with the possible effects of the FCN 945
    Settlement in its initial order, instead stating merely that the “costs were approved”
    already in the FCN 1150 Settlement, and it repeated this rationale in its clarifying
    order. Before this court, the Commission rightly concedes that the FCN 1150
    Settlement did not, as its orders indicated, guarantee full recovery of the costs
    allocated to the regulatory asset approved therein and instead permitted OPC to
    challenge recovery.     We therefore focus our analysis here on whether the
    Commission erred in concluding that the FCN 945 Settlement posed no bar to
    recovery of the RI/FS costs because, by its “plain language,” the FCN 945
    Settlement agreement applied only to stranded costs and “future operating costs.”
    Before we engage in this analysis, we address our standard of review.
    Broadly, our review of the Commission’s orders is limited. We defer to the
    Commission’s “findings of fact . . . unless it shall appear that such findings are
    unreasonable, arbitrary, or capricious.” Apartment & Off. Bldg. Ass’n of Metro.

    D.C. Code § 34-606
    ). And we will affirm the Commission’s

    under the circumstances.

    short, our deference is contingent on the Commission “fully and clearly explain[ing]
    what it does and why it does it.”

    , 739 (D.C. 2017) (“To permit
    meaningful judicial review, we require the Commission to explain its actions fully
    and clearly.” (brackets omitted)).
    Focusing more particularly on the FCN 945 Settlement—the basis for OPC’s
    challenge to the Commission’s initial and clarifying orders—the Commission argues
    that we are obligated to defer to its reading of this agreement. The Commission
    relies on a decision from the United States Court of Appeals for the D.C. Circuit,
    National Fuel Gas Supply Corp. v. Federal Energy Regulatory Commission, which
    states that the D.C. Circuit will “give deference to an agency’s reading of a
    settlement agreement even where the issue simply involves the proper construction
    of language.” 
    811 F.2d 1563
    , 1569 (D.C. Cir. 1987). But this decision is not binding
    12
    on our court, 6 and under our case law, it is far from clear that this court defers to any
    degree to the Commission’s interpretations of settlement agreements. See Grand
    Hyatt Wash. v. D.C. Dep’t of Emp. Servs., 
    963 A.2d 142
    , 146-47 (D.C. 2008)
    (“Settlement agreements . . . are contractual in nature and are interpreted under the
    same rules as contracts[,]” meaning “the written language will govern the parties’
    rights . . . .”); Dyer v. Bilaal, 
    983 A.2d 349
    , 355 (D.C. 2009) (“[W]e review de novo

    deference to agency interpretation is “based on the agency’s presumed expertise in
    construing the statute[s] it administers” (internal quotation marks omitted)). Even
    accepting for the sake of argument that deference to agency interpretation were
    warranted in this context, it would only be appropriate where there was ambiguous
    language and the agency’s interpretation of that language was reasonable. See
    MorphoTrust USA, Inc. v. D.C. Cont. Appeals Bd.,

    , 583 (D.C. 2015)

    13
    conditions must be met: (1) the statutory language in question must be ambiguous,
    and (2) the agency’s interpretation must be reasonable.” (internal parallel citation
    omitted)). We thus turn to the plain language of the settlement to see if we discern
    ambiguity in its terms. See D.C. Metro. Police Dep’t v. Pinkard, 
    801 A.2d 86
    , 90
    (D.C. 2002).
    The FCN 945 Settlement states that in future base rate proceedings “the
    Benning Road and Buzzard Point generating stations shall not be included in the cost
    of service” to be passed on to its customers. The Commission read this to mean that
    “the Benning Road and Buzzard Point generating stations[’ future operating costs]
    shall not be included in the cost of service.” But this provision of the settlement
    agreement contains no language limiting its application as to time (i.e., costs
    incurred in the past, present, or future) or as to types of costs that can be attributed
    to the generating station (i.e., only operating costs). The Commission simply read
    in language that is not there. At oral argument before this court, the Commission
    conceded that the plain language of the FCN 945 Settlement did not support its
    determination that the agreement only applied to future operating costs.           The
    Commission is bound by the plain language of the agreement that the parties signed
    and it approved.
    14
    Even so, interpretive questions remain regarding the scope of the application
    of the FCN 945 Settlement to the RI/FS costs at the Benning Road site. To the extent
    that the Commission is asking this court to conclude in the first instance that no
    RI/FS costs are actually attributable to the Benning Road generating station and
    thereby to uphold its determination that Pepco could pass on these costs to its
    distribution customers, we cannot do so. The exact scope of what costs may be
    attributed to the generating station is a complex and fact-intensive inquiry that
    cannot be answered on the record before us. For example, the basic question of how
    much of the 77-acre parcel of land at Benning Road was used for the generating
    station has yet to be addressed. The Commission seemed to acknowledge the
    complexity of these questions when it denied for the time being recovery of RI/FS
    costs incurred after the FCN 1150 Settlement and expressed “concerns about the
    past uses of the site and how costs for the RI/FS . . . should be allocated among
    generation, transmission, and distribution, and ultimately the amount that should be
    recovered from District distribution customers.”       Now that the Commission
    concedes that the FCN 1150 Settlement did not guarantee full recovery of the RI/FS
    costs discussed therein, see supra, the same concerns would presumably pertain.
    We therefore vacate the Commission’s order as to its approval of recovery of
    the Benning Road RI/FS costs and remand for the Commission to consider whether
    15
    the FCN 945 Settlement bars recovery of some or all of those costs. On remand, the
    Commission must provide a reasoned interpretation of the scope of the agreement
    based on substantial evidence and set out why under its interpretation the RI/FS costs
    are or are not within the settlement’s reach.
    II.    OPC’s Challenge to Inclusion of Energy Efficiency Programs in Pepco’s
    Rate Plan for Future Recovery
    A.     Facts and Procedural History
    While Pepco’s application in Formal Case No. 1156 for a multiyear rate plan
    including the recovery of RI/FI costs discussed above was still pending, the Covid-
    19 pandemic broke out. In response, the Commission requested further testimony
    from the parties to FCN 1156 reflecting the impact of the pandemic. Pepco
    submitted an “enhanced” plan that featured various revisions and, in pertinent part,
    proposed new energy efficiency rebate and loan (“EERL”) programs primarily
    targeting its small commercial customers. Pepco asked the Commission to approve
    the programs, the $5 million cost of which Pepco could later recover, along with a
    return at the associated cost of capital, 7 via a regulatory asset in a future rate case.
    7
    Pepco’s proposed asset treatment included an additional return on the carried
    balance of the assets at a rate authorized by the Commission. In other words, if
    16
    The Commission’s initial order approved Pepco’s proposed EERL programs,
    stating that it was “persuaded [the programs] are reasonable and will provide needed
    relief to customers during the Covid-19 pandemic.” In its request for reconsideration
    of the initial order, OPC challenged this decision, arguing that Pepco had failed to
    comply with a provision of the CleanEnergy DC Omnibus Amendment Act of 2018,
    which provides:
    As of October 1, 2019, the electric company . . . , after
    consultation and coordination with the Department of
    Energy and the Environment and the District [Sustainable
    Energy Utility (“SEU”)] and its advisory board, may apply
    to the Commission to offer energy efficiency and demand
    reduction programs in the District that the company can
    demonstrate are not substantially similar to programs
    offered or in development by the SEU, unless the SEU
    supports such programs.
    
    D.C. Code § 8-1774.07
    (g)(4).
    In its clarifying order, the Commission rejected this argument on two primary
    grounds: (1) because “§ 8-1774.07(g)(4) does not contain the words ‘shall’ or
    ‘must’” and “does not contain any sanctions or consequences for failing to
    granted recovery of the asset, Pepco would recover an additional set percentage of
    the asset value from its customers on top of the base recovery. That additional profit
    is referred to as the cost of capital.
    17
    coordinate with the SEU,” the statute was “directory” and not mandatory in nature,
    and (2) “Pepco made the determination that its program did not fall within the
    purview of this statute,” which the Commission deemed “reasonable” because the
    “overall intent of these statutory provisions” was to apply to “long-term [energy
    efficiency] programs primarily aimed at low-to-moderate-income customers,” not
    the short-term commercial programs proposed. 8
    This petition for review followed.
    B.      Analysis
    Where, as here, we are confronted with questions of statutory interpretation,
    we look first to the plain language of the statute and, if that language is ambiguous,
    then and only then do we defer to the Commission’s interpretation if reasonable.
    Pinkard, 
    801 A.2d at 90
    ; MorphoTrust USA, Inc., 115 A.3d at 583. Section
    8
    The Commission further concluded that it saw “no basis to conclude that
    Pepco violated the statute” absent a showing by OPC that the EERL program was
    duplicative of an SEU initiative, because the “overall intent” of § 8-1774.07 is “to
    prevent the duplication of [energy efficiency] and demand reduction programs that
    the SEU may be developing.” Finally, the Commission stated it was “reasonable
    and consistent with Commission precedent” for Pepco to place the costs of these
    programs in a recoverable regulatory asset because the programs were “in the public
    interest” and “help[] to address the District’s climate change commitments.”
    18
    8-1774.07(g)(4) of the D.C. Code provides that, “after consultation and coordination
    with” the DOEE and the DC SEU, an energy company like Pepco “may apply to the
    Commission to offer energy efficiency and demand reduction programs in the
    District.” We conclude that the Commission erred in determining both that this
    statute did not apply to the EERL programs included in Pepco’s multiyear rate plan
    and, even if it did apply, it did not require predicate steps by Pepco before including
    these programs in its application to the Commission.
    We first address what programs fall within the scope of 
    D.C. Code § 8-1774.07
    (g)(4).    By its plain language, the statute applies broadly and
    unambiguously to “energy efficiency and demand reduction programs in the
    District.” 
    D.C. Code § 8-1774.07
    (g)(4). This unquestionably describes Pepco’s
    proposed programs. The Commission’s determination to the contrary appears to rely
    on language in § 8-1774.07(g)(5) suggesting that the Commission must consider
    whether an application will primarily benefit low- and moderate-income residential
    ratepayers. 9 But this language does not qualify the scope of § 8-1774.07(g)(4).
    9
    
    D.C. Code § 8-1774.07
    (g)(5) provides that “[a]n application submitted by
    the electric company . . . pursuant to this subsection shall meet [1] the long-term and
    annual energy savings metrics, which shall primarily benefit low- and moderate-
    income residential ratepayers to the extent possible, [2] quantitative performance
    indicators, and [3] cost-effective standards established by the Commission.”
    19
    Section 8-1774.07(g)(5) discusses what factors the Commission should consider
    when evaluating the merits of an application it has already received.            The
    consultation-with-the-DOEE-and-SEU provision in § 8-1774.07(g)(4) outlines a
    step the company must take before submitting an application.
    Moreover, the Commission’s interpretation of D.C. § 8-1774.07(g)(4) is at
    odds with the District’s broader energy goals that underlie the statute and the
    administrative structure the District has established to pursue those goals. The
    Council for the District of Columbia created the SEU in the Clean and Affordable
    Energy Act of 2008, D.C. Act 17-497, 
    55 D.C. Reg. 9225
     (Oct. 22, 2008). The
    SEU’s express purpose is “to develop, coordinate, and provide programs for the
    purpose of promoting the sustainable use of energy in the District of Columbia.”
    
    D.C. Code § 8-1773.01
    (19) (emphasis added). Indeed, the legislative history of the
    SEU’s establishment reveals that the Council was motivated to create such a utility
    because Pepco and the Commission’s collective efforts to coordinate energy
    programs without further oversight were “not adequate” and “plainly [did] not
    work.” Report on Bill No. 17-492 before the Committee on Public Services and
    Consumer Affairs, Council of the District of Columbia, at 8-9, 12-13 (June 2, 2008).
    And the District added the specific language in subsection (g) to “clarif[y] that any
    energy efficiency or demand reduction program must be created in consultation with
    20
    the Department of Energy and the Environment and the Sustainable Energy Utility
    and its advisory board.” Amendment No. 1 to Bill No. 22-0904, D.C. Council, at 2
    (Nov. 27, 2018) (emphasis added). It would be irrational and counterproductive to
    carve out short-term programs targeting small business consumers from this
    administrative structure when District-wide coordination of “any” energy efficiency
    program is the statute’s manifest goal.
    Having determined that the proposed programs fall within the statute’s ambit,
    we further conclude that the consultation-with-the-DOEE-and-SEU provision in
    § 8-1774.07(g)(4) is mandatory by its plain language. Contrary to the Commission’s
    reasoning in its clarifying order, a statute need not contain the exact words “shall”
    or “must” in order to be mandatory. Here, the grammatical construction of the
    sentence leaves no room for Pepco to act at its discretion. To say an “electric
    company . . . , after consultation and coordination with the Department of Energy
    and the Environment and the District SEU and its advisory board, may apply to the
    Commission” means that that electric company “may not before such consultation
    apply to the Commission.” The Commission’s focus on the lack of express penalty
    was also misguided; as OPC correctly pointed out, the denial of any application
    submitted without the required consultation and coordination is sufficient
    consequence in itself.
    21
    In its brief to this court, the Commission takes a new approach and appears to
    argue that pursuant to its broad ratemaking authority under 
    D.C. Code § 34-1504
    (d)(1) (“Notwithstanding any other provision of law, the Commission may
    regulate the regulated services of the electric company through alternative forms of
    regulation” (emphasis added)), it has the power to waive the consultation-with-the-
    DOEE-and-SEU requirement. We cannot agree.
    We note at the outset that, because the Commission did not articulate the
    ability to grant such waivers as one of its stated grounds for granting Pepco’s request,
    we cannot affirm on this basis. Walsh v. D.C. Bd. of Appeals & Rev., 
    826 A.2d 375
    ,
    380 (D.C. 2003) (“An administrative order can only be sustained on the grounds
    relied on by the agency, and not on agency counsel’s post hoc rationalizations.”
    (cleaned up)). Furthermore, taking this argument at face value would yield absurd
    results. 10 Whatever the exact boundaries of the Commission’s authority under
    § 34-1504(d)(1), we need not define them in this case because §§ 8-1774.07(g)(4)
    and 34-1504(d)(1) “can be harmonized and deemed to have concurrent operation,”
    Stevens v. D.C. Dep’t of Health, 
    150 A.3d 307
    , 316 (D.C. 2016) (internal quotation
    10
    As the Commission conceded at oral argument, the Commission could not,
    for example, discriminate freely in disregard of the Human Rights Act so long as it
    did so while establishing an alternative form of regulation.

    marks omitted), alleviating any need to curb one for the benefit of the other. Section
    8-1774.07(g)(4) imposes a consultation requirement on Pepco prior to its application
    to the Commission; once an application has been properly presented to the
    Commission, the Commission retains its full regulatory authority over that
    application.
    Because Pepco was required by § 8-1774.07(g)(4) to consult with the DOEE
    and DC SEU prior to its application but the Commission granted its application in
    the absence of any evidence that Pepco complied with this prerequisite, we vacate
    the Commission’s order as to its approval of Pepco’s EERL programs. 11
    III.   Conclusion
    For the foregoing reasons, we vacate the Commission’s orders in relevant part
    and remand for further proceedings consistent with this opinion.
    So ordered.
    11
    We therefore do not reach the parties’ arguments regarding the
    Commission’s substantive assessment, see supra note 8, of whether the EERL
    programs would be duplicative of other SEU initiatives, or whether the programs
    meet the District’s climate change goals and serve the public interest.
