    Opinion by Arthur, J.
    ______________________________________
    Filed: January 28, 2016
    In 2013 the General Assembly enacted legislation enabling regulated gas
    companies to recover the estimated costs of certain infrastructure replacement projects
    through a surcharge on customer bills. See Md. Code (1998, 2010 Repl. Vol., 2014
    Supp.), § 4-210 of the Public Utilities Article (“PUA”). Shortly after the statute took
    effect, Baltimore Gas and Electric Company (“BGE”) sought approval of a plan to
    accelerate the replacement of outdated gas distribution infrastructure and to begin
    imposing a customer surcharge during the initial implementation of the plan. The Public
    Service Commission approved the plan, subject to the condition that BGE could not
    implement the surcharge until it submitted additional information about the individual
    infrastructure projects that were to be undertaken in 2014.
    The Circuit Court for Baltimore City affirmed the Commission’s order after the
    Office of People’s Counsel (“OPC”) petitioned for judicial review. On appeal, OPC
    contends: (1) that the Commission erred by authorizing BGE to collect estimated project
    costs before the completion of each project; and (2) that the Commission acted
    unlawfully by conditionally approving the plan before the Commission had evaluated the
    individual projects. We conclude that OPC has shown no basis for reversing the
    Commission’s decisions.
    LEGISLATIVE BACKGROUND
    A.     Parties to this Appeal
    This appeal involves three entities established by or regulated under the Public
    Utilities Article of the Maryland Code.
    The Maryland Public Service Commission is an independent unit in the executive
    branch of State government (PUA § 2-101(b)), with jurisdiction over public service
    companies that operate utility businesses within the State. PUA § 2-112(a). The
    Commission’s primary duties are to “supervise and regulate” the companies subject to its
    jurisdiction to “ensure their operation in the interest of the public” and to “promote
    adequate, economical, and efficient delivery of utility services in the State without unjust
    discrimination[.]” PUA § 2-113(a)(1)(i).
    BGE is a public service company regulated by the Commission. In general, public
    service companies have a duty to “furnish equipment, services, and facilities that are safe,
    adequate, just, reasonable, economical, and efficient, considering the conservation of
    natural resources and the quality of the environment.” PUA § 5-303. BGE provides gas
    service to approximately 655,000 customers across 800 square miles in Baltimore City
    and central Maryland.
    OPC is an agency that acts independently of the Public Service Commission. OPC
    has a duty to “appear before the Commission and courts on behalf of residential and
    noncommercial users in each matter or proceeding over which the Commission has
    original jurisdiction, including a proceeding on the rates, service, or practices of a public
    service company[.]” PUA § 2-204(a)(2).
    B.     Traditional Rate-Making Procedures
    Title 4 of the Public Utilities Article governs the Commission’s rate regulation
    authority. The Commission has “the power to set a just and reasonable rate of a public
    service company[.]” PUA § 4-102(b). A public service company has a corresponding
    duty to “charge just and reasonable rates for the regulated services that it renders.” PUA
    -2-
    § 4-201.
    In ordinary ratemaking proceedings, the Commission analyzes data from a prior
    “test year” to project a utility’s future income and expenses:
    The [Public Service Commission] establishes [just and reasonable] rates by
    examining the utility’s income and expenses during a test year, calculating
    the rate base (the fair value of the property used and useful in rendering
    service) during that year, determining the utility’s cost of capital (its
    required rate of return), and then multiplying that rate of return against the
    rate base. The result is the amount of income to which the utility is
    entitled. To the extent that level of income significantly differs from the
    test year’s net income, the Commission orders an adjustment in the utility’s
    rates – an increase or a decrease, as the case may be.
    Bldg. Owners & Managers Ass’n of Metro. Baltimore, Inc. v. Pub. Serv. Comm’n of
    Maryland, 
    93 Md. App. 741
    , 753 (1992); see Office of People’s Counsel v. Maryland
    Pub. Serv. Comm’n, 
    355 Md. 1
    , 8 (1999) (citing Pub. Serv. Comm’n of Maryland v.
    Baltimore Gas & Elec. Co., 
    273 Md. 357
    , 360 n.2 (1974)); Maryland People’s Counsel v.
    Heintz, 
    69 Md. App. 74
    , 84-85 (1986).
    In a conventional proceeding to set rates, the Commission will “calculate the test
    year’s rate base, i.e., ‘the fair value of the company’s property used and useful’ in
    rendering the service.” Severstal Sparrows Point, LLC v. Pub. Serv. Comm’n of
    Maryland, 
    194 Md. App. 601
    , 620 (2010) (quoting PUA § 4-101(3)). A public service
    company ordinarily is not entitled to recover costs simply because the costs were incurred
    prudently; instead, the Commission normally requires the company to show that the costs
    relate to an asset “used and useful” in providing service. E.g. Columbia Gas of
    Maryland, Inc. v. Pub. Serv. Comm’n of Maryland, 
    224 Md. App. 575
    , 584-86 (2015)
    (holding that Commission did not err in denying portion of gas company’s request for
    -3-
    rate increase that sought to recover anticipated remediation costs for property not used
    and useful in providing gas service).
    A recent rate case, In the Matter of the Application of the Washington Gas Light
    Company for Authority to Increase Its Existing Rates and Charges and to Revise Its
    Terms and Conditions for Gas Service, Order No. 84475, 102 Md. PSC 332 (2011),
    illustrates limits on this traditional recovery model. Along with a rate increase
    application, Washington Gas Light sought approval of an “Accelerated Pipe Replacement
    Plan,” by which it would finance replacement of its aging gas infrastructure through a
    customer surcharge. 
    Id. at 341,
    378-79. The Commission declined to approve that
    proposed surcharge, commenting that approving a surcharge merely because a company
    plans to increase its infrastructure investments “would represent a fundamental shift from
    long-standing rate-making principles[.]” 
    Id. at 342;
    see also 
    id. at 383.
    The Commission
    determined that the gas company could recover the costs of its plan by filing “more
    frequent rate cases” to adjust the rate “in smaller increments” after the assets were placed
    in service. 
    Id. at 342.1
    1
    Although the Commission has rejected several requests from utilities to approve
    surcharges to recover costs contemporaneously with improvements, in 2013 the
    Commission authorized Pepco, an electric distribution company, to impose a “tracker”
    surcharge mechanism to finance accelerated projects to improve grid resiliency. On an
    appeal resulting from that decision, this Court affirmed the Commission’s order without
    reaching the issue of whether the Commission has exceeded its statutory authority in
    approving the surcharge, as that issue had not been raised before the Commission.

    ___, No. 2173, Sept. Term 2014, slip op. at 26-28 (filed Dec. 15, 2015).

    C.     Enactment of the 2013 STRIDE Law
    Between 2011 and 2013, the General Assembly considered a series of bills that
    would empower the Public Service Commission to authorize gas companies to promptly
    recover infrastructure replacement costs through a customer surcharge.2 The 2013
    General Assembly enacted “An Act Concerning Gas Companies – Rate Regulation –
    Infrastructure Replacement Surcharge.” The proposal was commonly referred to as the
    Strategic Infrastructure Development and Enhancement (STRIDE) law. The law took
    effect on June 1, 2013. See 2013 Md. Laws, ch. 161, § 2.
    The legislation added section 4-210 to the Public Utilities Article. This new
    section includes an express statement of legislative intent: “It is the intent of the General
    Assembly that the purpose of this section is to accelerate gas infrastructure improvements
    in the State by establishing a mechanism for gas companies to promptly recover
    reasonable and prudent costs of investments in eligible infrastructure replacement
    projects separate from base rate proceedings.” PUA § 4-210(b).
    Pursuant to this section, a gas company may file “a plan to invest in eligible
    infrastructure replacement projects” accompanied by “a cost-recovery schedule . . . that
    includes a fixed annual surcharge to recover reasonable and prudent costs” of those
    projects. PUA § 4-210(d)(1). A plan filed by a gas company must include: “(i) a time
    line for the completion of each eligible project; (ii) the estimated cost of each project; (iii)
    a description of customer benefits under the plan; and (iv) any other information the
    2
    See S.B. 8, 2013 Reg. Sess. (cross-filed as H.B. 89); S.B. 541, 2012 Reg. Sess.
    (cross-filed as H.B. 662); S.B. 332, 2011 Reg. Sess. (cross-filed as H.B. 856).
    -5-
    Commission considers necessary to evaluate the plan.” PUA § 4-210(d)(2).
    The Commission is required to “take a final action to approve or deny the plan”
    within 180 days after the gas company files the plan. PUA § 4-210(e)(1)(ii). The
    Commission “may approve a plan if it finds that the investments and estimated costs of
    eligible infrastructure replacement projects are: (i) reasonable and prudent; and (ii)
    designed to improve public safety or infrastructure reliability over the short term and long
    term.” PUA § 4-210(e)(3).
    The term “[e]ligible infrastructure replacement” is defined as “a replacement or an
    improvement in an existing infrastructure of a gas company that: (i) is made on or after
    June 1, 2013; (ii) is designed to improve public safety or infrastructure reliability; (iii)
    does not increase the revenue of a gas company by connecting an improvement directly
    to new customers; (iv) reduces or has the potential to reduce greenhouse gas emissions
    through a reduction in natural gas system leaks; and (v) is not included in the current rate
    base of the gas company as determined in the gas company’s most recent base rate
    proceeding.” PUA § 4-210(a)(3).
    The cost-recovery schedule associated with a plan must include a fixed annual
    surcharge, which may not exceed $2 per month for each residential customer, and which
    is capped pursuant to a formula for non-residential customers. PUA § 4-210(d)(4)(i).
    After the approval of a plan, the gas company must file an annual reconciliation “to
    adjust the amount of a surcharge to account for any difference between the actual cost of
    a plan and the actual amount recovered under the surcharge.” PUA § 4-210(h). A
    surcharge established by the cost-recovery schedule “shall be in effect for 5 years from
    -6-
    the date of initial implementation of an approved plan.” PUA § 4-210(g)(1)(i).
    The statute sets forth specific requirements for calculating the “estimated cost” of
    each eligible project included in the plan. PUA § 4-210(d)(3). Of central importance to
    the instant appeal is a statutory provision that specifies when the estimated project costs
    may be recovered through the surcharge. Subparagraph (d)(3)(ii) provides that the
    “estimated project costs . . . are collectible at the same time the eligible infrastructure
    replacement is made.” PUA § 4-210(d)(3)(ii) (emphasis added).3
    FACTUAL AND PROCEDURAL BACKGROUND
    A.     BGE’s Application
    On August 2, 2013, one month after the effective date of the statute, BGE
    submitted an “Application . . . for Approval of a Gas System Strategic Infrastructure
    Development and Enhancement Plan and Accompanying Cost Recovery Mechanism.”
    According to the application, BGE wished to “accelerate significantly” the replacement
    of “gas system assets that have reached the end of their useful life,” in order to “enhance
    safety and reliability for its customers.”
    BGE proposed to completely replace the oldest and most leak-prone components
    3
    In full, subparagraph (d)(3)(ii) states: “The estimated project costs described in
    subparagraph (i) of this paragraph are collectible at the same time the eligible
    infrastructure replacement is made.” Subparagraph (i) provides that when calculating the
    estimated cost of each project, the gas company shall include the pretax rate of return on
    the company’s investment in the project, as well as depreciation and property taxes
    associated with the project. PUA § 4-210(d)(3)(i). Subparagraph (i) cross-references
    paragraph (2) of the subsection, which states that “[a] plan under this subsection shall
    include . . . the estimated cost of each project[.]”
    -7-
    of its gas distribution system over a period of 30 years. The application stated that BGE
    planned to replace the entire population of five “asset classes.”4 According to BGE,
    those assets had been installed many decades ago, in most cases more than 50 years
    earlier.
    BGE planned to invest a total of $400 million during the initial five-year period
    from 2014 to 2018. BGE proposed a monthly surcharge of $0.32 per residential customer
    and $1.87 per non-residential customer, beginning February 2014. The surcharge would
    then increase each year until 2017, when it would be capped at $2 per month for
    residential customers and $11.55 per month for non-residential customers.
    Upon receiving the application, the Commission suspended the proposed rates and
    initiated proceedings to evaluate the plan. OPC participated in the proceedings to
    represent the interests of ratepayers.5
    B.     Hearing Before the Commission
    The parties presented testimony and arguments at an evidentiary hearing on
    November 12, 13, and 14, 2013, in accordance with PUA § 3-107 and COMAR 20.07.02.
    In support of the application, four BGE executives testified regarding the details of
    4
    The application identified the assets as: “(1) pre-1982 plastic ‘Ski-Bar’ service
    risers, (2) Bare Steel Main, (3) Cast Iron Main, (4) Bare Steel Services, and (5) Copper
    Services.” In industry terminology, “mains” are gas distribution lines that serve as a
    common source for “service lines” that supply gas to individual customer meters.
    “Risers” are components that protect the service line as it transitions upward from below
    ground to the customer’s meter above the ground.
    5
    Maryland Energy Group and W.R. Grace & Co., groups comprised of large
    industrial and non-profit energy users, also intervened. Those parties submitted an initial
    brief, but presented no witnesses at the eventual hearing.
    -8-
    the proposed infrastructure replacements, the expected customer benefits, and the
    customer surcharge. According to BGE’s witnesses, the five “asset classes” described in
    the application represented only 21 percent of BGE’s gas distribution system mileage, but
    had accounted for 73 percent of all gas leak repairs in 2012. BGE estimated that the plan
    would roughly double the existing rate at which BGE had been replacing its pipelines.
    BGE’s proposal envisioned that customers would begin paying a surcharge on
    their monthly bills contemporaneously with, and in many cases after, its upgrades of the
    gas-delivery infrastructure. For example, the company expected to invest $65 million in
    its STRIDE projects in 2014 and to collect $3 million from customers that year.
    According to BGE, the total charges collected over five years would cover less than 10
    percent of BGE’s cumulative investments in the projects. The company would then
    recover the remainder of the costs over the useful life of the replaced assets.
    OPC offered testimony from Dr. Karl Pavlovic, an energy industry consultant,
    who recommended that the Commission deny the application. Among other things, Dr.
    Pavlovic contended that BGE’s plan was deficient in that it did “not identify or specify
    the investment costs” for replacing the targeted assets.
    Dr. Pavlovic opined that BGE’s proposed cost-recovery mechanism would
    contravene the established ratemaking principle that “investment cost recovery from rate
    payers does not begin until the associated assets are placed in service and used and
    useful.” He interpreted language from PUA § 4-210(d)(3)(ii), stating that “estimated
    project costs . . . are collectible at the same time the eligible infrastructure replacement is
    made,” to mean that “project costs can be included in the surcharge once a project is
    -9-
    completed.” (Emphasis added.) According to Dr. Pavlovic, the surcharge should not be
    based on future cost projections, but “should be calculated on actual historical costs in a
    [12] month period and collected over the subsequent 12 month period.” The foundation
    of his interpretation was his understanding that cost recovery under the new statute
    should be “consistent with the principles underlying the revenue requirement model[.]”
    Disputing Dr. Pavlovic’s interpretation, BGE and its witnesses contended that the
    intent of the legislation was to accelerate improvements by providing for prompt cost
    recovery contemporaneously with the implementation of the projects.
    The Commission’s staff also participated in the hearing pursuant to PUA §
    3-104(e). A staff engineer commented that BGE’s submissions were not detailed enough
    for staff to evaluate whether the plan met all statutory requisites for approval, because
    BGE had not identified specific projects to be implemented. The staff recommended that
    the Commission direct BGE to present a more detailed list of proposed 2014 projects
    within 30 days after an initial order, so that the Commission staff could ensure that each
    project met eligibility requirements. A BGE representative agreed to supply the
    remaining necessary information after the conclusion of the case.
    C.     The Commission’s Conditional Approval of the Application
    On January 29, 2014, the final day of the 180-day period for consideration of the
    application (see PUA § 4-210(e)(1)), the Commission issued Order No. 86147. The
    Commission set forth its findings and conclusions in a 40-page opinion that accompanied
    the order. The Commission declared: “[W]e find that BGE’s Application meets the
    requirements of [s]ection 4-210 and we conditionally grant the Company’s request. . . .
    -10-
    We approve the proposed cost recovery surcharge subject to the requirements set forth in
    [s]ection 4-210 and this Order.”
    The Commission nevertheless found BGE’s submissions to be lacking in a few
    important respects. Specifically, the Commission found that the BGE had not sufficiently
    identified the “time line for completion of each eligible project” and the “estimated cost
    of each project” pursuant to PUA § 4-210(d)(2)(i) and (ii). (Emphasis added.) As a
    result, the Commission could not yet determine whether the proposed investments and
    estimated costs were “reasonable and prudent” to qualify for approval under PUA §
    4-210(e)(3). The Commission wrote:
    According to BGE, the initial five year (2014-2018) estimated cost for its
    STRIDE Plan will be $400 million. BGE takes the position that each
    vintage asset class represents a “project.” Thus, according to BGE, the
    timeline for each project ranges from three years for the Ski-Bar risers to 30
    years for cast iron main and copper services. However, we conclude that
    the term “project” in Section 4-210(d)(2) means something more specific,
    concrete and practical than a broadly outlined plan. In fact, the Company
    essentially concedes as much, since BGE agreed to file a detailed list of
    2014 projects within 30 days of a Commission order approving its Plan, as
    Staff recommended, with the same level of detail as is found in the
    Company’s annual gas distribution system report. In order for the
    Commission to conclude that each project is reasonable and prudent both
    from an infrastructure and cost standpoint, we condition approval of BGE’s
    Plan . . . upon a Commission review of the time line and costs for each of
    BGE’s projects.
    The Commission directed BGE to file a list of projects to be initiated in 2014,
    along with the time lines and estimated costs for each project. The Commission gave
    BGE 30 days to file the list. It ordered that BGE could not implement the 2014 surcharge
    until after the Commission had approved the 2014 project list, time lines, and cost
    estimates. The Commission required BGE, each year thereafter, to submit information
    -11-
    about projects for the upcoming year.
    Addressing the question of statutory interpretation that had dominated much of the
    proceeding, the Commission concluded that BGE would not be required to await the
    completion of each infrastructure project before collecting the surcharge. The
    Commission recognized that “the new STRIDE statute represents a departure from
    traditional ratemaking principles.” The Commission emphasized that the express
    legislative purpose was that “reasonable and prudent costs” could be “recovered ‘separate
    from base rate proceedings.’” Consistent with that reading, the Commission determined
    that the statutory provision “that estimated project costs ‘are collectible at the same time
    the eligible infrastructure replacement is made’ . . . authorizes contemporaneous cost
    recovery at the time eligible infrastructure replacement work is being performed.”
    The Commission clarified, however, that “estimated project costs may not be
    recovered by the surcharge until BGE has begun making its initial STRIDE
    replacements.” In a footnote, the Commission added that it anticipated that approval of
    those submissions would be completed “at an Administrative Meeting after Staff and the
    Commission have had a reasonable time to review BGE’s project filing.”
    At the conclusion of Order No. 86147, the Commission ordered that BGE’s
    STRIDE plan was “approved, subject to the acceptance by BGE of the conditions
    contained in this Order[.]” The Commission also ordered BGE to notify the Commission
    within 30 days whether it would accept all conditions contained in the order. Finally, the
    Commission ordered that the plan would be denied if BGE failed to do so.
    -12-
    D.     Developments after the Conditional Approval
    On February 21, 2014, BGE formally notified the Commission that it had accepted
    the conditions imposed by Order No. 86147. BGE submitted a list of 55 projects to be
    initiated in 2014, “including project description, location, estimated cost, type of
    infrastructure replaced, risk assessment . . . , estimated project completion date[,] and
    reasons for replacement.” Citing changed circumstances since the initial application,
    BGE estimated a decrease in capital expenditures for 2014 projects. BGE also asked the
    Commission to authorize higher surcharges for residential customers and for most
    categories of non-residential customers.
    Shortly thereafter, on February 27, 2014, OPC filed a petition for judicial review
    in the Circuit Court for Baltimore City. Both the Commission and BGE filed responses.
    Meanwhile, OPC submitted comments to the Commission regarding BGE’s 2014
    projects. The parties again appeared at the Commission’s administrative meeting on
    March 26, 2014, at which the Commission heard arguments, but did not receive any new
    sworn testimony. The Commission’s staff announced that it had reviewed the project list
    and recommended that the Commission approve the completed application. The
    commissioners voted to approve the projects and to authorize BGE to impose the
    requested surcharges effective April 2014. The Commission issued a letter order after the
    meeting to formalize its decision.
    In the action for judicial review in the circuit court, OPC challenged aspects of
    both Order No. 86147 and the March 26, 2014, letter order. Among other things, OPC
    contended that the Commission had erred by concluding that the statute authorized BGE
    -13-
    to collect estimated project costs before the proposed projects were completed and by
    conditionally approving the plan before the Commission had received a list of projects.
    At a hearing on September 5, 2014, the circuit court issued an oral decision denying
    OPC’s petition. On September 12, 2014, the circuit court entered an order affirming
    Order No. 86147.
    OPC noted a timely appeal from the circuit court’s judgment.
    QUESTIONS PRESENTED
    OPC presents the following two questions, which we quote:
    1.     Did the Commission act unlawfully and in contravention of PUA §
    4-210(d)(3)(ii), when it issued Order No. 86147, in which the
    Commission authorized BGE to begin collection of the estimated
    cost of each eligible infrastructure replacement before it was made?
    2.     Did the Commission act unlawfully when it issued Order No. 86147,
    in which the Commission approved BGE’s STRIDE Plan even
    though the Commission found that the Plan did not consist of
    “projects” as expressly required by PUA §§ 4-210(d)(1) and (e)(3)?
    As discussed below, OPC has failed to show that the Commission erred or
    otherwise acted unlawfully.
    DISCUSSION
    I.
    The Public Utilities Article “sets forth the limited ‘scope of review’ . . . over
    decisions by the Public Service Commission.” Town of Easton v. Pub. Serv. Comm’n,
    
    379 Md. 21
    , 30 (2003). It states: “Every final decision, order, or regulation or the
    Commission is prima facie correct and shall be affirmed unless clearly shown to be: (1)
    unconstitutional; (2) outside the statutory authority or jurisdiction of the Commission; (3)
    -14-
    made on unlawful procedure; (4) arbitrary or capricious; (5) affected by other error of
    law; or (5) if the subject of review is an order entered in a contested proceeding after a
    hearing, unsupported by substantial evidence on the record considered as a whole.” PUA
    § 3-203 (emphasis added).
    The appellate court’s task is to review the Commission’s decision, not the decision
    of the circuit court. See Mid-Atlantic Power Supply Ass’n v. Maryland Pub. Serv.
    Comm’n, 
    143 Md. App. 419
    , 432 (2002).
    A.     Commission’s Interpretation of Cost Collection Provisions
    As the primary issue in this appeal, OPC contends that an “error of law” affected
    the Commission’s order. OPC specifically contends that the Commission erred when it
    interpreted the statute as authorizing a gas company to recover estimated project costs
    after the initial implementation of the projects and before the completion of each project.
    OPC’s challenge concerns the language of a provision describing the “estimated costs”
    included with a gas company’s infrastructure replacement plan: “The estimated project
    costs . . . are collectible at the same time the eligible infrastructure replacement is made.”
    PUA § 4-210(d)(3)(ii).
    In a section of the opinion titled “OPC’s Objections,” the Commission wrote:
    OPC argued that project costs may not be included in the surcharge until
    projects are completed. The traditional rate base recovery models have
    only allowed utilities to collect revenues based upon assets that are
    currently used and useful. However, in this case there is legislation that
    specifically states that the estimated project costs “are collectible at the
    same time the eligible infrastructure replacement is made,” and that
    reasonable and prudent costs shall be recovered “separate from base rate
    proceedings.” The statute authorizes contemporaneous cost recovery at the
    time eligible infrastructure replacement work is being performed.

    The parties disagree over the appropriate weight that should be given to this
    interpretation.
    Generally, “[a] great deal of discretion is necessarily vested in the Commission in
    order that it may properly discharge its important and complex duties.” People’s Counsel

    deference,” but “[t]hat deference is, by no means, dispositive” and not as great as the
    deference owed to factual findings.

    include whether agency officials adopted their view “soon after its passage” (Office of
    People’s Counsel v. Maryland Pub. Serv. 
    Comm’n, 355 Md. at 16
    ), whether the
    interpretation “has been applied consistently and for a long period of time,” “the extent to
    which the agency engaged in a process of reasoned elaboration in formulating its
    -16-
    interpretation,” and “the nature of the process through which the agency arrived at its
    interpretation[.]”

    (quoting Baltimore Gas & Elec. Co. v. Pub. Serv. 
    Comm’n, 305 Md. at 161-62
    ) (quotation marks omitted).
    OPC urges this Court to grant little or no weight to the Commission’s
    interpretation of PUA § 4-210(d)(3)(ii), because these proceedings presented the
    Commission with its “first opportunity” (Wallace H. Campbell & Co., Inc. v. Maryland
    Comm’n on Human Relations, 
    202 Md. App. 650
    , 671 (2011)) to construe the newly
    enacted statute. Although this 2014 interpretation of the 2013 law had not yet been
    applied consistently over a long period of time, other relevant considerations indicate that
    the Commission’s interpretation deserves deference.
    OPC asserts that the Commission provided “little (if any) elaboration in
    formulating its interpretation.” According to OPC, “the Commission’s discussion and
    interpretation – in its entirety – of . . . PUA § 4-210(d)(3)(ii)” consists of a single
    paragraph. We disagree that the Commission’s analysis was so limited. Earlier portions
    of the opinion extensively discussed competing interpretations of the provision offered by
    the parties. The opinion included analysis of section 4-210 in its entirety, from which the
    Commission drew inferences regarding how the legislature intended to motivate gas
    companies to accelerate infrastructure replacements. The opinion later cited
    subparagraph (d)(3)(ii) to support the conclusion that “estimated project costs may not be
    recovered by the surcharge until BGE has begun making its initial STRIDE
    replacements[.]” As a whole, the well-considered opinion provided a reasoned
    elaboration of this provision within its statutory context.
    -17-
    Further examination of the record reveals that the adversarial presentation of this
    issue sharpened the Commission’s statutory analysis. In addition to written testimony
    regarding the meaning of the subparagraph, one of the commissioners examined OPC’s
    witness, Dr. Pavlovic, regarding OPC’s preferred interpretation. OPC’s expert testified
    that the statute’s reference to the “time” when a gas company makes a replacement could
    refer to a number of things, including “when the underlying asset is in the process of
    being put in the ground” or “not until . . . the asset is in the ground and functioning.” He
    opined that the Commission should equate the time the eligible infrastructure
    replacement “is made” with the time that the replacement has been “placed in service.”
    The commissioner asked Dr. Pavlovic to explain why the statute would refer to the
    recovery of “estimated” costs if the gas company could not collect the costs until the
    replacement had been “placed in service,” when the actual costs would already be known.
    Dr. Pavlovic commented that the reference to a cost estimate amounted to “an
    inconsistency or ambiguity as it were in the legislation.” He encouraged the Commission
    to use its own expertise where the statute was “unclear” and to resolve the question by
    applying principles of the conventional recovery model. The commissioner, by contrast,
    expressed doubt that there would be any need for the new statute if the traditional cost-
    recovery principles continued to apply:
    [COMMISSIONER:]           But coming back to your testimony, you would
    have liked the statute to have said placed in
    service before cost could be recovered?
    DR. PAVLOVIC:             I would like the statute to have said placed in
    service, recovery – this provision is talking about
    the recovery. Recovery will begin when the asset
    -18-
    is placed in service.
    [COMMISSIONER:]           I know you’re not a lawyer, but a lot of your
    testimony deals with your view of the statute. . . .
    That’s why I’m trying to clarify in my mind, if the
    statute wanted to say placed in service, it could
    have easily said placed in service. That’s a pretty
    common phrase in utility regulation; is it not?
    DR. PAVLOVIC:             Yes.
    [COMMISSIONER:]           Are you familiar at all with the concept that if
    somebody thinks part of the statute is ambiguous,
    that you have to try to read the statute as a whole
    so that no terms are rendered meaningless or
    incorrect?
    DR. PAVLOVIC:             Yes.
    [COMMISSIONER:]           So if we took your reading of the statute that the
    recovery only occurs after the asset is placed in
    service, what do we do with the estimated budget
    cost of that same subsection of the statute?
    After reading the language once more, Dr. Pavlovic commented, “the statute, it’s
    difficult here.” He concluded his answer by saying: “I mean to square this provision
    with, as I said, what I understand to be the overall intent, which is to apply the traditional
    revenue requirement model to the recovery of this investment, but to – in a more timely
    manner, I can’t make these completely consistent and I certainly admit that.”
    Like the Commission’s written explanation of its decision, the hearing transcript
    demonstrates that the agency engaged in a thorough reasoning process in formulating its
    interpretation. Normally, this Court owes deference when an agency has “carefully
    considered the statutory language during an adversarial adjudicatory proceeding and
    issued [a] formal, written opinion[] that detail[s] the reasons for reaching its conclusion,”
    -19-
    as long as the agency’s interpretation does not clearly violate the wording of the statute.

    222 Md. App. 347
    , 357 n.7
    (concluding that this Court normally would defer to an interpretation expressed by the
    Workers’ Compensation Commission in written opinion after adversarial hearing, but
    ultimately holding that the relevant language unambiguously supported the agency’s
    interpretation), cert. granted, 
    443 Md. 234
    (2015).
    Giving weight to the Commission’s interpretation would be particularly
    appropriate here where even OPC, the party challenging the Commission’s interpretation,
    advanced the position that the statute was ambiguous and encouraged the agency to use
    its expertise to determine the meaning of potentially ambiguous terms. See Baltimore
    Gas & Elec. Co. v. Pub. Serv. 
    Comm’n, 305 Md. at 159
    (stating that the presence of a
    vague term susceptible to more than one interpretation “in an administrative statute such
    as the Public Service Commission Law suggests that the General Assembly intended to
    entrust the formulation of specific standards to the technical expertise of those charged
    with enforcing the statute”). As compared to this Court, the Commission certainly
    possesses far greater expertise in deciding how to accomplish the legislative purpose of
    accelerating infrastructure improvements through a surcharge.
    We are unconvinced that the Commission’s interpretation carries minimal or no
    authoritative weight. Because the Commission has “clearly demonstrate[d] that it has
    focused its attention on the statutory provisions in question, thoroughly addressed the
    relevant issues, and reached its interpretation through a sound reasoning process,” its
    interpretation should “be accorded the persuasiveness due a well-considered opinion of
    -20-

    Comm’n, 305 Md. at 161-62
    )
    (quotation marks omitted). As explained below, however, even upon a plenary review of
    this issue, we would arrive at the same answer as the Commission.
    B.     Meaning of Section 4-210(d)(3)(ii) of the Public Utilities Article
    When interpreting a provision of the Public Utilities Article, as with any other
    statute, we first examine the ordinary meaning of the enacted language, “reading the
    statute as a whole to ensure that no word, clause, sentence or phrase is rendered
    surplusage, superfluous, meaningless or nugatory.” Peters v. Early Healthcare Giver,
    Inc., 
    439 Md. 646
    , 665 (2014) (quoting Nichols v. Suiter, 
    435 Md. 324
    , 339 (2013))
    (quotation marks omitted). A court may neither add nor subtract words to alter the
    meaning of statutory terms and must avoid forced or subtle constructions that limit or
    extend a statute’s application. See, e.g., Clipper Windpower, Inc. v. Sprenger, 
    399 Md. 539
    , 553 (2007). “In every case, the statute must be given a reasonable interpretation, not
    one that is absurd, illogical, or incompatible with common sense.” Espina v. Jackson,
    
    442 Md. 311
    , 322 (2015) (citations omitted); Lockshin v. Semsker, 
    412 Md. 257
    , 276
    (2010).
    OPC contends that the Commission violated these principles by “improperly
    substitut[ing] its own preferred words, phrases, and tenses that the Commission believed
    the General Assembly should have chosen.” OPC highlights some differences between
    the words of PUA § 4-210(d)(3)(ii) (“estimated project costs . . . are collectible at the
    same time the eligible infrastructure replacement is made”) and words from the
    -21-
    conclusion stated in the opinion: “The statute authorizes contemporaneous cost recovery
    at the time eligible infrastructure replacement work is being performed.” According to
    OPC, the Commission “rewrote” the provision to say that “estimated project costs . . . are
    collectible at the time the eligible infrastructure replacement work, including
    preconstruction planning, has begun or is being performed.”6
    But even as it criticizes the Commission for rewriting (or, more precisely,
    paraphrasing) the statutory language, OPC then goes on to offer its own paraphrase of
    PUA § 4-210(d)(3)(ii). According to OPC, subparagraph (d)(3)(ii) means that “STRIDE
    Project costs may not be collected from residential ratepayers in the STRIDE surcharge
    until (and unless) each STRIDE project for which ratepayers are being charged has been
    ‘made,’ or completed.” (Emphasis added.)
    OPC’s analysis focuses most acutely upon a single word – “made.” OPC asserts
    that “the verb ‘made’” was “used in its simple past tense.” Citing online dictionaries,
    OPC tells us: “‘Made’ means ‘built, formed, or shaped in a particular way.’ . . . Further,
    ‘made is the ‘simple past tense and past participle of ‘make,’ which means that it refers to
    something that has already been ‘built, formed or shaped in a specified way.”7
    6
    The opinion does not mention cost recovery during a “preconstruction planning”
    phase. OPC’s inaccurate characterization is not based upon the language of the opinion
    but upon certain testimony from BGE witnesses. Later in the opinion, the Commission
    specifically clarified that estimated costs “may not be recovered by the surcharge until
    BGE has begun making its initial STRIDE replacements,” which we interpret to mean
    that BGE may not recover the costs until construction work has begun.
    7
    In support of this proposition, OPC cites a web page accessed on July 20, 2015:
    http://dictionary.reference.com/browse/made?s=t. The source does say that the word
    “made” is the “simple past tense and past participle of make.” It does not say that the
    -22-
    OPC’s parsing of the sentence is flawed. An example of the verb “to make” used
    in the “simple past tense” is: “The gas company made a replacement.” Subparagraph
    (d)(3)(ii), however, does not employ that formulation. Instead, the subparagraph uses the
    word “made” as a participle along with the present tense verb “is” – the estimated costs
    become collectible at the same time the replacement “is made.” In other words,
    subparagraph (d)(3)(ii) uses the verb “to make” in the present tense, but in the passive
    voice. A simplified example of that passive formulation is: “The replacement is made by
    the gas company.” The active-voice equivalent of that sentence is: “The gas company
    makes the replacement,” using the present tense. Translated from the passive to the
    active voice, the meaning of “at the same time the eligible infrastructure replacement is
    made” is substantially similar to “at the same time the gas company makes the eligible
    infrastructure replacement.”
    OPC’s interpretation might be accurate if the statutory language had employed the
    passive voice and the present perfect tense, so that it provided that estimated project costs
    become collectible at the same time “the eligible infrastructure replacement has been
    made.” That reading, however, would not reflect the language as actually enacted, in the
    passive voice and present tense.
    Our ultimate question of interpretation is to determine when the “estimated project
    costs . . . are collectible[.]” PUA § 4-210(d)(3)(ii). The statute directs that those
    meaning of the word is restricted to “something that has already been” made. Nor does it
    discuss the meaning of the phrase “is made,” which is the actual language in the pertinent
    statute.
    -23-
    estimated costs may be collected “at the same the eligible infrastructure replacement is
    made.” 
    Id. The Commission
    interpreted this phrase, within the statutory context, to
    mean that costs may be collected once a gas company begins making the infrastructure
    replacements. OPC contends that the only permissible reading of this sentence is that the
    gas company may not collect the costs until it finishes making the replacements.
    Depending on the context, a reference to the “time” something “is made” could
    refer to either the period of time during which something is being made (“we’ll listen to
    music while dinner is made”) or the point in time when the process of making something
    has been completed (“dinner is made; let’s eat”). In subparagraph (d)(3)(ii), the potential
    ambiguity is resolved by the clarifying phrase “at the same time.” Under OPC’s
    interpretation, the “time” an infrastructure replacement “is made” represents a discrete
    instant: after that moment, the gas company may recover a surcharge, but before that
    moment, the company may not recover anything. The statute, however, contemplates
    that the surcharge will be paid not at one discrete time, but over a long period of time.
    Specifically, the surcharge “shall be in effect for 5 years from the date of initial
    implementation of an approved plan,” and the surcharge may continue for certain
    ongoing projects even after that five-year period. PUA § 4-210(g)(1).
    Under OPC’s reading, a gas company would never be permitted to collect the
    costs “at the same time” the replacement “is made”; it could recover costs only after the
    replacement has been made or completed. The timing of the two actions (replacement
    and collection) would always be different and would never be “the same.” OPC’s
    interpretation at worst contradicts the meaning of the phrase “at the same time,” and at
    -24-
    best renders that term meaningless.8 Under fundamental principles of construction, we
    must reject OPC’s interpretation because it fails to account for the General Assembly’s
    use of the word “same.” See, e.g., Chow v. State, 
    393 Md. 431
    , 453-55 (2006) (rejecting
    interpretation of statute that would render word “transfer” in statute meaningless or
    nugatory).
    Of course, to understand the meaning of statutory language, we must look beyond
    individual words and clauses to the larger context, including other surrounding provisions
    and the apparent purpose of the enactment. See, e.g., Williams v. Peninsula Regional
    Med. Ctr., 
    440 Md. 573
    , 580-81 (2014) (citing 
    Lockshin, 412 Md. at 275-76
    ). This
    additional context casts further doubt upon OPC’s suggested interpretation.
    This sentence in PUA § 4-210(d)(3)(ii) does not describe the collection of mere
    “costs,” but the collection of “estimated project costs” that are to be included in an
    application. Subsection (d), which governs the contents of a plan filed by a gas company,
    specifies that a plan must include “a cost-recovery schedule associated with the plan that
    includes a fixed annual surcharge on customer bills to recover reasonable and prudent
    costs of proposed eligible infrastructure replacement projects.” PUA § 4-210(d)(1)(ii).
    Subsection (d) is predominantly forward-looking. The gas company files a “plan” for
    “proposed . . . projects” along with “estimated” costs. Overall, this language suggests
    8
    At the judicial review hearing, the circuit court judge proposed the following
    hypothetical: “Suppose I said to my granddaughter, ‘Be quiet while the fudge is made.’”
    Counsel for OPC replied that “in that context,” he “would concede” that the word
    “while” is a “durational term,” which implies that that the sentence refers to the time the
    fudge “is being made.” Much like the word “while,” the phrase “at the same time”
    conveys the duration of the action.
    -25-
    that a surcharge reflecting estimated costs may be recovered before the gas company has
    completed all of the work and before the actual costs are known.
    Other portions of the statute are explicitly backward-looking. Most notably, the
    statute requires a gas company, after the approval of a plan, to file an annual
    reconciliation “to adjust the amount of a surcharge to account for any difference between
    the actual cost of a plan and the actual amount recovered under the surcharge.” PUA §
    4-210(h) (emphasis added). This feature of the statute strengthens the implication that
    the gas company can begin to recover its costs before it has completed all of the work and
    before the actual amount of the costs are known.
    Subsection (d) is not the only provision to address cost collection. Elsewhere, the
    statute directs: “A surcharge under this section shall be in effect for 5 years from the date
    of initial implementation of an approved plan.” PUA § 4-210(g)(1)(i). Under the most
    reasonable reading of this sentence, a customer surcharge begins to take effect on the date
    that the gas company initially implements its plan. Under OPC’s interpretation, the
    surcharge would not be “in effect” from the initiation of the approved plan, but would
    take effect much later, after the completion of projects.
    At best, OPC’s reading is in substantial tension with many features of the statute.
    OPC’s interpretation would render the word “same” in PUA § 4-210(d)(3)(ii) essentially
    meaningless; it struggles to explain why the provision refers to “estimated” costs that
    would need to be adjusted to reflect the “actual” costs at the end of the year; and it
    substantially undermines the overlapping direction that the surcharge mechanism takes
    effect “from the date of initial implementation[.]” PUA § 4-210(g)(1)(i). By contrast,
    -26-
    the Commission’s interpretation is consistent with section 4-210 in its entirety.
    C.     Effect of “Just and Reasonable Rate” Definition of PUA § 4-101
    OPC largely ignores the tension between its strained interpretation of
    subparagraph (d)(3)(ii) and the surrounding provisions. OPC does, however, encourage
    this Court to look beyond the statute and to infuse the reading of section 4-210 with other
    factors usually considered in the traditional rate-of-return regulatory model. We reject
    that approach because, by all objective indications, the STRIDE law represents a
    departure from that conventional model.
    OPC posits that, because a surcharge is a “rate,” the surcharge must also meet the
    enumerated requirements of a “just and reasonable rate.” Within the rate regulation title,
    the term “‘just and reasonable rate’ means a rate that: (1) does not violate any provision
    of [the Public Utilities A]rticle; (2) fully considers and is consistent with the public good;
    and (3) . . . will result in an operating income to the public service company that yields,
    after reasonable deduction for depreciation and other necessary and proper expenses and
    reserves, a reasonable return on the fair value of the public service company’s property
    used and useful in providing service to the public.” PUA § 4-101. In OPC’s view, the
    language that “estimated project costs are collectible . . . at the same time the eligible
    infrastructure replacement is made” should be treated as restating the requirement of
    PUA § 4-101(3) that a public service company is authorized to earn a return on property
    that is “used and useful” in providing service to the public.
    In response, the Commission argues that it makes little sense to attempt to
    “reconcile” the new STRIDE surcharge mechanism with traditional recovery models.
    -27-
    The Commission concedes that, in the traditional ratemaking context, the Commission
    “disfavors tracker surcharges” that permit a utility to begin recovering costs from
    ratepayers immediately upon expenditure. The Commission argues, however, that the
    General Assembly “has expressed a clear desire that the Commission deviate from that
    position” when evaluating surcharges under the STRIDE law because the language of
    PUA § 4-210 makes it “quite clear” that “the STRIDE Act was intended as an exception
    to traditional ratemaking.”
    OPC’s argument has a number of infirmities. First and foremost, the defined term
    “just and reasonable rate” does not appear in section 4-210. The General Assembly
    easily could have incorporated the “used and useful” component by adding the defined
    term “just and reasonable rate” to surcharge provisions of the STRIDE law. We must
    respect the legislature’s choice not to do so. See, e.g., Toler v. Motor Vehicle Admin.,
    
    373 Md. 214
    , 223-24 (2003) (explaining that decision to employ defined term in one
    section but different term in another part of statute dealing with same overall subject
    usually indicates that legislature intends two different meanings).
    The statute here conspicuously indicates the opposite of any intention to make the
    surcharge comport with the methods of traditional base rate cases. The General
    Assembly expressly stated its intent to “establish[] a mechanism for gas companies to
    promptly recover reasonable and prudent costs . . . separate from base rate proceedings.”
    PUA § 4-210(b) (emphasis added). The statute ensures this separation by prohibiting the
    Commission from “consider[ing] a revenue requirement or rate-making issue that is not
    related to the plan when reviewing a plan for approval or denial unless the plan is filed in
    -28-
    conjunction with a base rate case.” PUA § 4-210(e)(5).
    The General Assembly established new and distinct standards for evaluating a
    request for a customer surcharge pursuant to the STRIDE law. Specifically, the STRIDE
    surcharge is designed “to recover reasonable and prudent costs of proposed eligible
    infrastructure replacement projects.” PUA § 4-210(d)(1)(ii) (emphasis added). The
    “investments and estimated costs” recovered through the surcharge must be: “(i)
    reasonable and prudent; and (ii) designed to improve public safety or infrastructure
    reliability over the short term and long term.” PUA § 4-210(e)(3) (emphasis added).
    Section 4-210 does not guarantee the gas company a reasonable return on the fair value
    of assets used and useful in providing service, as in the traditional rate-of-return model;
    instead, it merely permits the gas company, between base rate cases, to recover certain
    “reasonable and prudent” costs through surcharges that do not exceed a statutory
    maximum. The adjustments to scrutinize the replaced infrastructure under a traditional
    rate analysis do not occur until a post-approval rate case. See PUA § 4-210(d)(5)-(6);
    PUA § 4-210(g); PUA § 4-210(i).
    The STRIDE law is not the first instance in which the General Assembly has
    established a rate mechanism procedurally and substantively distinct from conventional
    ratemaking. In Office of People’s Counsel v. Maryland Pub. Serv. Comm’n, 
    355 Md. 1
    (1999), the Court of Appeals rejected the notion that rates set outside the traditional
    regulatory scheme must strictly satisfy the statutory criteria for “just and reasonable
    rates.” In 1995, the General Assembly had enacted legislation authorizing an alternative
    method for setting telecommunications rates, to permit greater price flexibility than was
    -29-
    provided by the traditional recovery model. 
    Id. at 9.
    The 1995 statute (currently codified
    at PUA § 4-301) provided that, notwithstanding the statutory definition of just and
    reasonable rates, the Commission could regulate telephone companies through alternative
    forms of price regulation to ensure “affordable and reasonably priced” service. Pursuant
    to that statute, the Commission established telecommunications rates through a price-cap
    regulatory plan, which it considered to be a “‘broader and more forward-looking measure
    of rate reasonableness’” than the traditional rate-of-return measures. Office of People’s
    Counsel v. Maryland Pub. Serv. 
    Comm’n, 355 Md. at 7
    , 11.
    OPC challenged that price regulation, contending that the “affordable and
    reasonably priced” criterion of the new statute was in addition to, rather than a substitute
    for, the definition of “just and reasonable rates.” 
    Id. at 20-21.
    Rejecting that view, the
    Court focused upon the statutory definition of “just and reasonable rates,” which included
    the requirement that rates “‘will result in an operating income to the public service
    company . . . yielding . . . a reasonable return upon the fair value of the company’s
    property used and useful in rendering service to the public.’” 
    Id. at 8-9
    (quoting former
    art. 78, § 69(a)). The Court reasoned that this defined term “requires a traditional rate
    analysis to be made from a specified comparison of costs, rates[,] and profits[.]” 
    Id. at 23.
    Those enumerated criteria for evaluating justness and reasonableness do not apply
    when the Commission regulates a utility by means of an alternative mode of regulation
    that does not use a traditional rate-of-return methodology. 
    Id. at 23-24.
    The new
    statute’s guarantee of “‘affordable and reasonably priced’” service acted as the
    “equivalent” of the general mandate that a utility charge “‘just and reasonable rates.’” 
    Id. -30- at
    24.
    Similarly, in Severstal Sparrows Point, LLC v. Pub. Serv. Comm’n of Maryland,
    
    194 Md. App. 601
    , 620 (2010), this Court concluded that the definition of a “just and
    reasonable rate” in PUA § 4-101 did not apply to another form of regulation “outside the
    realm of traditional rate-of-return ratemaking.” In that case, this Court construed a 1999
    statute that obligated electricity suppliers to offer certain customers “‘backstop’
    electricity supply, known as Standard Offer Service[.]” 
    Id. at 605.
    The statute required
    the service to be offered “at a market price that permits recovery of the verifiable,
    prudently incurred costs to procure or produce the electricity plus a reasonable return.”
    PUA § 7-510(c)(3)(ii)(2). In addition, the statute gave the Commission limited oversight
    to ensure that the price was procured “in a manner that is designed to obtain the best price
    for residential and small commercial customers[.]” PUA § 7-510(c)(4)(ii)(1).
    Ultimately, this Court concluded that the Commission erred when it attempted to graft
    elements of a traditional rate case onto this more abbreviated oversight process,
    controlled by statutory criteria other than section 4-101. Severstal Sparrows 
    Point, 194 Md. App. at 622-26
    .
    Consistent with these authorities, we conclude that the Commission is not required
    to evaluate the justness and reasonableness of a customer surcharge under the 2013
    STRIDE law based strictly on criteria that are associated with the traditional base rate
    recovery models. Section 4-210 authorizes a surcharge “outside the traditional
    ratemaking process.” Severstal Sparrows 
    Point, 194 Md. App. at 619
    (citing Office of
    People’s Counsel v. Maryland Pub. Serv. 
    Comm’n, 355 Md. at 23
    ). The Code
    -31-
    undoubtedly mandates that BGE charge “just and reasonable” rates for its gas service.
    See PUA § 4-201; Office of People’s Counsel v. Maryland Pub. Serv. 
    Comm’n, 355 Md. at 25
    . Yet, in this context, the requirements that costs recovered through the surcharge be
    reasonable, prudent, and otherwise in accordance with section 4-210 serve as the
    “equivalent” of that standard. Office of People’s Counsel v. Maryland Pub. Serv.
    
    Comm’n, 355 Md. at 24
    . The Commission here correctly declined OPC’s invitation to
    overwrite the STRIDE methodology with elements of the traditional rate-of-return
    methodology where neither the statutory language, nor the statutory scheme, nor logic
    compels the application of those principles here.9
    D.     Confirmation Through Other Indicia of Legislative Intent
    Even if we agreed that this statute were reasonably susceptible to the alternative
    interpretation offered by OPC, our next task would be to consult “other indicia of
    9
    BGE argues that the “used and useful” component of the “just and reasonable
    rate” definition does not prohibit the Commission from authorizing concurrent surcharges
    before assets are placed in service. BGE points out that “[t]he meaning and the concept
    of the words ‘used and useful in rendering service to the public’ have been held to have a
    certain elasticity since the phrase first came into use.” Baltimore Gas & Elec. Co. v.
    McQuaid, 
    220 Md. 373
    , 379 (1959). Thus, even in an ordinary rate case, the rate-setting
    body might be able to consider certain assets that, although not currently in use, are
    “likely to be placed in service within the period for which the rates are fixed.” 
    Id. at 380.
    According to BGE, the surcharges approved by the Commission comport with PUA § 4-
    101(3) because there is “some measure of certainty” that the assets not currently in use
    “will in fact be coming into use shortly[.]” Bldg. Owners & Managers Ass’n of Metro.
    Baltimore, Inc. v. Pub. Serv. Comm’n of Maryland, 
    93 Md. App. 741
    , 770-71 (1992). As
    a result of our holding that PUA § 4-210 authorizes a surcharge separate from the
    ordinary rate setting process, it is unnecessary to decide the extent to which the
    Commission, pursuant to its ordinary ratemaking powers, may approve contemporaneous
    surcharges based on cost projections.
    -32-
    legislative intent . . . , including the relevant statute’s legislative history, the context of
    the statute within the broader legislative scheme, and the relative rationality of competing
    constructions.” Harrison-Solomon v. State, 
    442 Md. 254
    , 265-66 (2015) (citing Witte v.
    Azarian, 
    369 Md. 518
    , 525-26 (2002)). OPC’s reading finds no support in these sources.
    The Commission’s construction is faithful to the express “purpose and intent” of
    the General Assembly, which was “to accelerate gas infrastructure improvements . . . by
    establishing a mechanism for gas companies to promptly recover reasonable and prudent
    costs . . . separate from base rate proceedings.” PUA § 4-210(b) (emphasis added).
    OPC’s construction of the statute would do little to accomplish the General Assembly’s
    stated aims. In contrast to OPC’s, the Commission’s interpretation represents a more
    reasonable method of accelerating a gas system overhaul because it allows substantially
    more prompt cost recovery than previously available under base rate proceedings.
    Although there is little need to look beyond the pages of the Maryland Code to
    ascertain the meaning of this provision, other materials associated with this statute’s
    legislative history confirm the Commission’s interpretation.10 A summary of the law
    prepared by the Department of Legislative Services states: “The estimated project costs
    approved in the surcharge are collectible during the same time the eligible infrastructure
    replacement is being made.” Fiscal and Policy Note for S.B. 8 (2013 Reg. Sess.), at 2.
    10
    Even where the words of a statute make its meaning clear, courts may consider
    legislative history and other external manifestations of legislative intent to confirm the
    correctness of the interpretation. See, e.g., Guttman v. Wells Fargo Bank, 
    421 Md. 227
    ,
    239-40 (2011).
    -33-
    The report goes on to assess the probable effect of the legislation on ratepayers, operating
    under that assumption: “[T]here is a mismatch between the recovery of infrastructure
    costs and the benefits from the infrastructure investment. As a result, it could be said that
    the risk of recovery for the company is reduced – i.e. shifted to ratepayers by virtue of the
    fact that ratepayers pay for the costs earlier.” 
    Id. at 8.
    Because the Court of Appeals has
    often treated similar materials as persuasive evidence of the apparent intent of the
    General Assembly (e.g. Gomez v. Jackson Hewitt, Inc., 
    427 Md. 128
    , 177-78 (2012);
    Moore v. State, 
    388 Md. 623
    , 635-36 & n.4 (2005)), it would also be appropriate to do so
    here.
    In addition to its “plain language” arguments, OPC rounds out its brief with some
    criticisms of the policy of allowing utilities to begin recovering costs before assets have
    been placed in service. OPC and other interested parties presented these and other
    concerns to members of the General Assembly at a hearing of the Senate Finance
    Committee on January 7, 2013.11 In our view, OPC’s policy criticisms should be directed
    to the General Assembly, not to the Maryland courts.
    The essence of OPC’s argument is that, by enacting these words – “the estimated
    project costs . . . are collectible at the same time the eligible infrastructure replacement is
    made” – the General Assembly prohibited gas companies from recovering estimated
    costs until after each project has been completed. Although OPC argues that that is

    -34-
    “plain” to OPC, it was not plain to the Department of Legislative Services, or to the
    parties who protested to the General Assembly that the legislation would enable gas
    companies to begin charging customers before benefits accrued to those customers. Even
    Dr. Pavlovic, OPC’s expert witness before the Commission, did not contend that the
    statute “plainly” or unambiguously dictates OPC’s preferred result.
    The statute neither says nor means that “costs may not be collected from
    residential ratepayers in the STRIDE surcharge until (and unless) each STRIDE project
    . . . has been ‘made,’ or completed[.]” Properly construed, “[t]he statute authorizes
    contemporaneous cost recovery at the time eligible infrastructure replacement work is
    being performed.” The Commission did not err.
    II.
    As its first issue in this appeal, OPC challenged the correctness of an interpretation
    of the statute expressed in the Commission’s opinion. OPC’s second asserted grounds
    are nowhere near as clearly defined as the first. Throughout its brief and reply brief, OPC
    variously accuses the Commission of “act[ing] unlawfully,” “exceed[ing] its statutory
    authority,” “refus[ing] to follow clear statutory mandates,” ignoring “procedural
    requirements,” making an “improper reading of the law,” erring in “how it applied [its]
    interpretations to the facts,” and making a decision based on information that was “not in
    the evidentiary record[.]”
    In considering these arguments, we are again guided by the standard of judicial
    review, under which “Commission decisions are presumptively correct” (People’s
    Counsel v. Pub. Serv. 
    Comm’n, 52 Md. App. at 722
    ), and the petitioner bears the burden
    -35-
    to “clearly show[]” the Commission’s decision to be unconstitutional, outside statutory
    authority, made on unlawful procedure, arbitrary or capricious, affected by legal error, or
    unsupported by substantial evidence. PUA § 3-203. To some extent, OPC’s challenge
    concerns whether the Commission exceeded the regulatory powers vested in it by the
    General Assembly, powers which are “truly awesome[.]” Baltimore Gas & Elec. Co. v.
    Pub. Serv. Comm’n of Maryland, 
    75 Md. App. 87
    , 99 (1988). The Commission not only
    has powers “specifically conferred by law” but also “the implied and incidental powers
    needed or proper to carry out its functions,” and those powers must be “construed
    liberally.” PUA § 2-112.
    OPC’s characterization of this alleged error varies, but OPC does advance one
    unifying theme. According to OPC, “the Commission erred when it failed to follow the
    express language in PUA § 4-210(d)(1)(i) and (e)(3) by authorizing BGE to begin
    recovering estimated costs for an eligible infrastructure replacement even though it
    determined the plan had no ‘projects.’” OPC relies on subparagraph 4-210(d)(1)(i),
    which authorizes a gas company to file “a plan to invest in eligible infrastructure
    replacement projects[.]” (Emphasis added.) OPC also points to paragraph (e)(3), which
    authorizes the Commission to approve a plan based on findings about “the investments
    and estimated costs of eligible infrastructure replacement projects[.]” (Emphasis added.)
    OPC argues that the STRIDE law “requires the Commission to review ‘projects’ prior to
    approving a ‘plan.’” The Commission, by contrast, granted a preliminary approval of
    -36-
    BGE’s broader program, conditioned on subsequent annual reviews of those projects.12
    Although paragraph (a)(3) enumerates criteria for evaluating whether a project is
    an “eligible infrastructure replacement project,” the statute does not describe what
    constitutes a “project.” Instead, the definitions subsection states: “‘Project’ means an
    eligible infrastructure replacement project proposed by a gas company in a plan filed
    under this section.” PUA § 4-210(a)(5). The statute defines a “[p]lan” within section
    4-210 to mean “a plan that a gas company files under subsection (d) of this section.”
    PUA § 4-210(a)(4). By using these vague and self-referential definitions for “project”
    and “plan,” the General Assembly indicated that it “intended to entrust the formulation of
    specific standards to the technical expertise” of the Commission. Baltimore Gas & Elec.
    Co. v. Pub. Serv. Comm’n of 
    Maryland, 305 Md. at 159
    . This contested proceeding
    presented the Commission with its first opportunity to articulate those standards.
    In its opinion, the Commission expanded upon the meaning of the term “project.”
    12
    In its brief, BGE has argued that this Court should not reach the merits of the
    second question on appeal. BGE contends that any issues related to approval of the 2014
    project list are now moot because the Commission failed to take a second “appeal” after
    the Commission issued the March 26, 2014, letter order. This argument is misplaced.
    Order No. 86147, which expressly contemplated further proceedings before the ultimate
    approval of the surcharge, “was at least arguably not a final reviewable order without the
    implementing Letter Order.” Mid-Atlantic Power Supply Ass’n v. Maryland Pub. Serv.
    Comm’n, 
    143 Md. App. 419
    , 458 (2002). The arguably premature filing of OPC’s
    petition, however, did not limit the circuit court’s jurisdiction. Because a petition for
    judicial review is not an “appeal” but an original action, the time requirements for filing a
    petition for judicial review are not jurisdictional. Kim v. Comptroller of Treasury, 
    350 Md. 527
    , 535 (1998). Consequently, the circuit court had the power to grant appropriate
    relief from both orders, even if the January 29 order was not a final order for the purpose
    of judicial review, because the Commission issued the letter order before any proceedings
    took place in the circuit court. See 
    id. at 534-36;
    see also ABF Freight Sys., Inc. v.
    Gilchrist, 
    125 Md. App. 419
    , 424-26 (1999).
    -37-
    BGE had taken the position that each “asset class” qualified as a single “project.”
    Operating on that assumption, BGE submitted time lines ranging from three years to 30
    years for the replacement of the different asset classes, while providing total cost
    estimates for each the initial five years of implementation. The Commission concluded
    that these general estimates were inadequate, explaining that “the term ‘project’ in
    [s]ection 4-210(d)(2) means something more specific, concrete[,] and practical than a
    broadly outlined plan.” Put differently, the Commission concluded that BGE had
    provided information for five categories of projects, without identifying the individual
    projects within those categories.
    The Commission “agree[d] with OPC in its interpretation” that the gas company
    must submit project costs and time lines for each project so that the Commission could
    “establish the reasonableness and prudence of the projects.” The Commission declared
    that “BGE must meet the statutory requirements to provide the costs and timeline for
    completion of each project before surcharge recovery may commence.” Thus, contrary to
    OPC’s assertion on appeal, the Commission did not authorize “BGE to begin recovering
    estimated costs . . . even though it determined the plan had no ‘projects.’” In fact, the
    Commission did the opposite. The immediate effect of Order No. 86147 was to prohibit
    BGE from imposing the surcharge as of January 29, 2014, subject to later review of a list
    of 2014 projects.13
    13
    If the Commission had failed to take action on January 29, 2014, the last day of
    the 180-day statutory review period, BGE would have been authorized to implement the
    plan even without an approval. See PUA § 4-210(f)(1).
    -38-
    OPC takes no issue with the Commission’s conclusions about the level of
    specificity required for the “projects” included with a gas company’s plan, and OPC
    agrees with the conclusion that review of a project list, along with estimated costs and
    time lines, was necessary before authorizing the surcharge. Moreover, OPC has not
    disputed that BGE complied with the Commission’s conditions when it submitted the
    necessary project list on February 21, 2014, which the Commission subsequently
    reviewed and approved at the administrative meeting on March 26, 2014. For that
    reason, by the time that the Commission actually authorized BGE to begin collecting the
    customer surcharge, the substantive basis for OPC’s objections no longer existed: BGE
    had identified “projects” for 2014, and the Commission had reviewed the reasonableness
    and prudence of those projects as required by the statute. The same characteristic of
    Order No. 86147 to which OPC objects – the Commission’s multi-step process for
    reviewing the plan – was precisely the feature that ensured that the ultimate decision
    would comport with the statute.
    OPC protests, however, that by inviting BGE to make “after-the-fact changes to its
    plan,” the Commission “prevent[ed] full review prior to approval of the plan[.]” OPC
    theorizes that “the project modifications and surcharge changes” from BGE’s filing on
    February 21, 2014, “amounted to amendments that should have been treated under the
    120-day schedule provided for in paragraph (e)(2).” Yet assuming that the Commission
    should have treated BGE’s updated project list as an amendment, the Commission was
    not necessarily required to wait any particular period of time or to conduct a full hearing
    before acting on those amendments. The statute sets a 120-day maximum period for
    -39-
    considering an amendment, not a 120-day minimum. See PUA § 4-210(e)(2) (“Within
    120 days after a gas company files an amendment to an approved plan, the Commission
    shall take final action to approve or deny the amendment”). The statute includes no
    specific requirement of a hearing on an amendment to a plan. In general, the Public
    Utilities law directs the Commission to “institute and conduct proceedings reasonably
    necessary and proper to the exercise of its powers or the performance of its duties.” PUA
    § 3-104(a)(1).
    As illustrated by this Court’s opinion in Building Owners and Managers Ass’n of
    Metropolitan Baltimore, Inc. v. Pub. Serv. Comm’n of Maryland, 
    93 Md. App. 741
    , 764-
    72 (1992) (“BOMA”), the Public Service Commission has considerable discretion in
    deciding whether to require separate proceedings for reviewing different elements of a
    rate request. In BOMA, at the conclusion of a conventional rate case, the Commission
    had authorized a “two-step increase” in BGE’s electricity rates, granting an immediate
    rate increase and also authorizing BGE to file an amended rate schedule several months
    later when a new plant was expected to begin operation. 
    Id. at 746.
    The Commission
    directed the company to file revised tariff schedules, along with data necessary for the
    Commission to verify the reasonableness of the second rate increase. 
    Id. at 766-77.
    The
    Commission determined that it was unnecessary and against the public interest to require
    a separate and expensive proceeding that would only repeat much of the presentation
    from the first hearing. 
    Id. at 766.
    For that reason, the Commission accepted the final
    submissions as a compliance filing for an administrative meeting, giving the parties the
    opportunity to express their views without formal testimony. 
    Id. at 767.
    -40-
    On appeal in BOMA, OPC contended that the Commission had acted arbitrarily,
    acted without substantial evidence, and deprived ratepayers of due process when it
    approved the second rate increase without a new proceeding and a full hearing. 
    Id. at 768-69.
    This Court rejected those arguments, holding that the Commission did not abuse
    its discretion or act unlawfully by refusing to require an entirely new, and largely
    duplicative, rate case. 
    Id. at 771-72.
    In light of the reasoning of BOMA, there is nothing
    inherently objectionable about the type of multi-step procedure used here by the
    Commission.
    After a contested hearing in this case, the Commission had already determined,
    based on BGE’s initial submissions, that projects to replace assets in the categories
    targeted by BGE would qualify as eligible infrastructure replacement projects and would
    improve public safety and infrastructure reliability. The Commission required more
    information to reach a conclusion as to whether “each proposed project [wa]s reasonable
    and prudent both from an infrastructure and cost standpoint,” in accordance with PUA §
    4-210(e)(3). Having already reviewed the company’s overarching program, the
    Commission decided to make those remaining determinations through a series of
    abbreviated proceedings, first by reviewing the projects and estimated costs for 2014,
    followed by review of annual filings in each of the subsequent four years.
    OPC argues that, under these circumstances, such a “conditional approval” was
    unlawful, and that the Commission’s only option was to deny BGE’s application. In
    essence, OPC asks this Court to invalidate the Commission’s approval of the 2014
    projects and surcharge and to send all parties back to the beginning of the process. OPC
    -41-
    concludes: “if BGE wishes to proceed again under § 4-210 for recovery of these costs,
    the parties should be provided an opportunity to determine what, if any, of BGE’s
    projects meet the statutory requirements, and then, and only then, may the Commission
    determine if it wishes to approve a plan and whether a surcharge crafted in accordance
    with § 4-210 may be imposed upon customers.”
    The Commission has already provided that relief (“an opportunity to determine
    what, if any, of BGE’s projects meet the statutory requirements”) through its multi-step
    approval. The process devised by the Commission eliminated unnecessary delay, while
    also ensuring that ratepayers would not pay surcharges in 2014 and in subsequent years
    until after the Commission had determined that the proposed projects and estimated costs
    were reasonable and prudent. We see no unlawfulness or abuse of discretion in the
    Commission’s informed decision to invite BGE to amend its proposals and to review
    those amendments at an informal administrative meeting, rather than to require an
    entirely new proceeding.
    CONCLUSION
    For the reasons stated in this opinion, we affirm the judgment of the circuit court,
    which affirmed the decision of the Public Service Commission. OPC has not clearly
    shown that the Commission based its decision on an error of law or that the decision was
    otherwise unlawful.
