  •       TEXAS COURT OF APPEALS, THIRD DISTRICT, AT AUSTIN
    NO. 03-03-00386-CV
    Cities of Alvin, Dickinson, Fort Stockton, Friendswood, La Marque, League City,
    Lewisville, and Texas City; Office of Public Utility Counsel;
    and State of Texas, Appellants
    v.
    Public Utility Commission of Texas; First Choice Power, Inc.; and Alliance
    for Retail Markets, Appellees
    FROM THE DISTRICT COURT OF TRAVIS COUNTY, 200TH JUDICIAL DISTRICT
    NO. GN203764, HONORABLE JOHN K. DIETZ, JUDGE PRESIDING
    OPINION
    This appeal concerns the Public Utility Commission’s order increasing the fuel-factor
    component of the price-to-beat for First Choice Power, Inc. When appellants1 sought judicial review
    of that order, the district court dismissed the case in part, concluding that many of appellants’
    challenges were untimely challenges to the validity of the rule governing fuel-factor adjustments.
    In the alternative, the court affirmed the order. We will affirm the district court’s judgment.
    1
    Appellants are the Cities of Alvin, Dickinson, Fort Stockton, Friendswood, La Marque,
    League City, Lewisville, and Texas City (“the cities”); the Office of Public Utility Counsel (“OPC”);
    and the State of Texas.
    BACKGROUND
    Texas is in transition from a regulated market for electricity toward a competitive
    market for the production and sale of electricity. See State v. Public Util. Comm’n, 
    131 S.W.3d 314
    ,
    318-20 (Tex. App.—Austin 2004, pet. filed) (“2003 Rulemaking Case”); see also Tex. Util. Code
    Ann. ch. 39 (West Supp. 2004); see generally 
    id. §§ 11.001-64.158
    (West 1998 & Supp. 2004)
    (“PURA”). As part of the transition, integrated utilities were required to “unbundle” into companies
    that respectively generate, transmit and distribute, and provide electricity; the unbundled companies
    may be wholly separate or remain affiliated. PURA § 39.051(b).
    During the transition period, the Public Utility Commission (“the Commission”) sets
    a price-to-beat for affiliated retail electric providers (“AREPs”) that provide electricity to residential
    and small commercial customers. See PURA § 39.202(a). The price-to-beat is the base rate of the
    utility affiliated with the AREP (6% less than the utility’s rate charged on January 1, 1999) as
    modified by the fuel factor, which adjusts the price-to-beat to account for changes in fuel prices. 
    Id. Previously, the
    fuel factor was set so that the utility could recover its estimated fuel
    cost; the resulting fees charged for fuel were later reconciled with the utility’s actual fuel expenses.
    See PURA § 36.203; see also Nucor Steel v. Public Util. Comm’n, 
    26 S.W.3d 742
    , 745 (Tex.
    App.—Austin 2000, pet. denied). Companies could not automatically pass through their fuel costs
    (PURA § 36.201), and were required to show efficient generation, effective cost controls, and
    negotiation of the lowest reasonable fuel cost for its non-affiliated contracts. 
    Nucor, 26 S.W.3d at 745
    (citing 17 Tex. Reg. 7067 (1992), amended 18 Tex. Reg. 836 (1993)). For purchases from
    affiliated providers, the utility also had to show that the fuel expenses were reasonable and necessary
    2
    and that the affiliate did not charge the utility any more than it did other utilities in a similar class.
    
    Nucor, 26 S.W.3d at 745
    .
    During the transition period, the showing necessary to obtain an adjustment of the fuel
    factor is streamlined. An AREP may request that the Commission adjust the fuel factor up to twice
    per year by demonstrating that “the existing fuel factor does not adequately reflect significant
    changes in the market price of natural gas and purchased energy used to serve retail customers.”
    PURA § 39.202(l). The Commission’s rule implementing subsection (l) provides in relevant part
    as follows:
    An affiliated retail electric provider may request that the commission adjust the fuel
    factor(s) established under subsection (f)(3) of this section not more than twice in a
    calendar year if the affiliated retail electric provider demonstrates that the existing
    fuel factor(s) do not adequately reflect significant changes in the market price of
    natural gas and purchased energy used to serve retail customers. . . . The
    methodology for calculating the adjustment to the fuel factor(s) shall be the
    following:
    (A) For each business day of the ten-day period ending no more than ten business
    days before the filing of a fuel factor adjustment application, an average of the
    closing forward 12-month NYMEX Henry Hub natural gas prices, as reported
    in the Wall Street Journal, is calculated.
    (B) The average forward price for each business day calculated in subparagraph (A)
    of this paragraph will then be averaged to determine a ten-day rolling price.
    (C) The percentage difference between the averaged ten-day rolling price calculated
    under subparagraphs (A) and (B) of this paragraph and the averaged ten-day
    rolling price used to calculate the current fuel factor(s) is calculated. If the
    current fuel factor was calculated through an adjustment under subparagraph (E)
    of this paragraph, then the averaged ten-day rolling price calculated concurrent
    with that adjustment shall be used. If the percentage difference is 4.0% or more,
    the current fuel factor(s) may be adjusted.
    3
    (D) To adjust the current fuel factor(s), the percentage difference is added to one and
    then multiplied by the current factor(s). The results are the adjusted fuel
    factor(s) that will be implemented according to the procedural schedule in clause
    (i) and (ii) of this subparagraph:
    (i) if no hearing is requested within 15 days after the petition has been filed,
    a final order shall be issued within 20 days after the petition is filed;
    (ii) if a hearing is requested within 15 days after the petition is filed, a final
    order shall be issued within 45 days after the petition is filed.
    26 Tex. Reg. 2680, 2707 (2001) (“Rule 25.41(g)(1)”).2 When adopting rule 25.41, the Commission
    recognized “the undeniable fact that REPs [retail electric providers], affiliated or not, will not incur
    costs after 2002 based on a historic fuel mix; rather, all REPs will be purchasing power in the
    market.” 26 Tex. Reg. at 2692.
    This Court upheld rule 25.41 against a challenge that the Commission failed to
    establish a sufficient headroom—the difference between the price-to-beat and the sum of non-
    bypassable charges approved by the Commission. See Reliant Energy, Inc. v. Public Util. Comm’n,
    
    62 S.W.3d 833
    , 838 (Tex. App.—Austin 2001, no pet.). Although no party in the original
    rulemaking process directly appealed the use of the NYMEX index3 to assess and correct
    2
    The rule was amended in part by 28 Tex. Reg. 3249 (2003). The successive versions of
    the rule were codified at 16 Tex. Admin Code § 25.41. For convenience, we will refer to the version
    adopted in 2001 as “rule 25.41” and the amended version adopted in 2003 as “amended rule 25.41.”
    3
    The “NYMEX index” in this case is the New York Mercantile Exchange index of the
    closing forward 12-month natural gas prices at the Henry Hub. It is published in the Wall Street
    Journal. The Commission will compute an average of the prices each day (see rule 25.41(g)(1)(A)),
    then average those averages (see rule 25.41(g)(1)(B)). See State v. Public Util. Comm’n, 
    131 S.W.3d 314
    , 319 n.3 (Tex. App.—Austin 2004, pet. filed) (“2003 Rulemaking Case”).
    4
    inadequacies in the fuel factor, this Court later upheld amended rule 25.41 against challenges to the
    use of the NYMEX index, among other issues. See 2003 Rulemaking Case, 131 S.W.3d. at 322-25.
    On May 9, 2002, First Choice applied to the Commission to increase its fuel factor
    under rule 25.41. The Commission found that First Choice’s fuel factor was originally set based on
    a natural gas price of $3.111/MMBtu4, and the relevant average natural gas price on the NYMEX
    index for ten business days from April 24, 2002 through May 7, 2002 was $3.817/MMBtu—an
    increase of 22.69%. The Commission found that it had previously concluded that the NYMEX gas
    index was representative of the price of natural gas and purchased energy, and that a 4% change in
    that price would satisfy minimally the requirement in utility code section 39.202 for “significant”
    change. The Commission determined that, because rule 25.41 was defined as the exclusive means
    of showing changes in the price of natural gas for this purpose, evidence of First Choice’s actual
    costs and revenues was irrelevant; the only change First Choice had to show was the change in the
    NYMEX index. The Commission also concluded that the rate ceiling for the price-to-beat contained
    in PURA section 39.202(p) is not applicable to fuel factor adjustments under PURA section
    39.202(l). Based on this demonstrated “significant” increase of greater than 4% in the price of
    natural gas and purchased energy used to serve retail customers, the Commission raised First
    Choice’s fuel factor by 22.69%; the Commission found that First Choice’s fuel factor would rise
    from 2.18¢/kWh5 to 2.67¢/kWh, causing a typical residential customer using 1000 kWh per month
    to pay an additional $4.93 per month.
    4
    MMbtu stands for one million British thermal units, a unit of measurement of gas.
    5
    kWh stands for kilowatt hour, a measure of energy.
    5
    The Commission also concluded that a statutory provision requiring electric utilities
    to reimburse the cities’ reasonable expenses for participating in a ratemaking proceeding does not
    apply in this case because First Choice is an AREP, not an electric utility. See PURA §§ 33.023
    (requiring electric utilities to pay expenses), 31.002(6)(H) (excluding retail electric providers from
    definition of electric utility).
    Appellants sought judicial review of the Commission’s order. The district court
    found that most of appellants’ challenges were actually directed to the validity of rule 25.41 and
    should have been brought in the original rulemaking challenge. Consequently, the court determined
    that the validity challenges brought in this ratemaking proceeding were untimely and that it had no
    jurisdiction over them; the court alternatively denied the challenges.6 The court also denied the
    6
    The challenges over which the district court concluded it lacked jurisdiction included
    challenges by all appellants. It included the following:
    OPC’s assertions that the Commission (1) exceeded its authority by increasing the fuel
    factor without requiring First Choice to demonstrate the statutorily mandated factors—i.e., that the
    existing fuel factor does not adequately reflect significant changes in the market price of natural gas
    and purchased energy used to serve retail customers, (2) acted arbitrarily and abused its discretion
    by basing its decision on criteria irrelevant under PURA section 39.202(l) and rule 25.41(g)(1) and
    by failing to consider criteria relevant under these provisions, (3) acted arbitrarily and abused its
    discretion by raising the fuel factor without substantial evidence that the fuel factor did not
    adequately reflect significant changes in the market prices of natural gas and purchased energy used
    to serve retail customers as required by these provisions, (4) acted arbitrarily and abused its
    discretion by raising the fuel factor without making findings of fact on the market prices of natural
    gas and purchased energy used to serve retail customers, the significance of changes in the market
    prices, and the inadequacy of the fuel factor to reflect those changes, and (5) improperly excluded
    evidence of First Choice’s costs and revenue, rendering its decision unsupported by substantial
    evidence and violative of PURA section 39.202(l) and rule 25.41(g)(1).
    The State’s assertions that the Commission eliminated the statutory requirement that First
    Choice demonstrate that the existing fuel factor does not adequately reflect significant changes in
    the market price and violated constitutional and statutory due-process requirements by imposing a
    6
    challenges timely and appropriately brought in this ratemaking proceeding, including contentions
    that the fuel-factor adjustment increased the price-to-beat to an impermissible level and that First
    Choice was required to reimburse the cities’ expenses incurred in this proceeding.
    DISCUSSION
    The State, OPC, and the cities raise several issues on appeal. Because many of these
    issues overlap, we will discuss them as if they were raised collectively. Appellants assert that the
    district court erred by concluding that it lacked jurisdiction to consider their challenges, excluding
    evidence of First Choice’s actual costs and windfall profits, rendering a judgment not supported by
    substantial evidence or necessary findings of fact, setting the price-to-beat too high, finding no
    violation of due process in the 45-day time limit, and failing to require First Choice to reimburse the
    cities’ costs.
    JURISDICTION
    The district court concluded that it lacked jurisdiction over most of appellants’
    challenges to the Commission’s order because they were untimely challenges to the validity of rule
    25.41 that were filed in the wrong court. A validity challenge “tests a rule on procedural and
    45-day time limit for processing fuel-factor adjustments.
    The cities’ assertions that the Commission failed to consider evidence of the price First
    Choice actually paid for natural gas and power used to serve retail customers and improperly
    authorized a windfall for First Choice, violating PURA section 39.202(l) and rule 25.41(g)(1) by
    failing to require First Choice to demonstrate that the existing fuel factor does not adequately reflect
    significant changes in the market price of natural gas and purchased energy used to serve retail
    customers.

    constitutional grounds.” 2003 Rulemaking 
    Case, 131 S.W.3d at 321
    (citing Eldercare Props., Inc.
    v. Texas Dep’t of Human Servs., 
    63 S.W.3d 551
    , 558 (Tex. App.—Austin 2001, pet. denied)). The
    scope of a validity challenge also includes whether the agency had statutory authority to promulgate
    the rule. Railroad Comm’n v. ARCO Oil and Gas Co., 
    876 S.W.2d 473
    , 477 (Tex. App.—Austin
    1994, writ denied). PURA requires as follows: “A person who challenges the validity of a
    competition rule must file a notice of appeal with the court of appeals and serve the notice on the
    commission not later than the 15th day after the date on which the rule as adopted is published in
    the Texas Register.” PURA § 39.001(f). Because appellants failed to file these challenges in this
    Court within 15 days after the adopted rule was published, the district court determined that it did
    not have jurisdiction over the validity challenges; the court alternatively decided the merits of
    appellants’ challenges and denied them.
    Appellants contend that the district court had jurisdiction because they challenge the
    application of the rule, not its validity. An applicability challenge does not question the general
    validity of a rule, but seeks a judicial declaration regarding the application of the rule in a particular
    fact situation. 
    Eldercare, 63 S.W.3d at 558
    . Appellants describe the district court’s decision as the
    application of a new and radical form of res judicata, and they caution that a company unaware that
    a rule affecting it was being adopted would find itself subject to the rule without recourse.
    Appellants assert that courts have jurisdiction to review Commission decisions, and that validity
    challenges generally may be pursued through declaratory-judgment actions. See PURA § 15.001;
    Tex. Gov’t Code Ann. §§ 2001.038, .174 (West 2000) (part of the Administrative Procedures Act
    [“APA”]). Appellants argue that, because the rule uses the language of the statute, the basis for their
    8
    challenges was not apparent until the Commission misapplied it. They also contend that they
    challenge, not the language of the rule, but the Commission’s failure to follow the rule by conflating
    the rule’s provisions, excluding relevant evidence, and raising the fuel factor based on an inadequate
    record.   They further contend that, between the adoption of the rule and its application,
    circumstances demonstrated that the Commission’s theories supporting the rule were not borne
    out—e.g., the NYMEX index proved not to accurately represent the market price of natural gas and
    purchased energy. They also warn that limiting challenges to the transition rules sets a precedent that
    will haunt future litigants in administrative proceedings and increase this Court’s case load.
    Appellants urge that we have discussed the scope of challenges permissible in district
    court in a case that, while distinguishable, should guide us to consider all of their challenges in this
    ratemaking proceeding. See City Pub. Serv. Bd. of San Antonio v. Public Util. Comm’n, 
    96 S.W.3d 355
    (Tex. App.—Austin 2002, no pet.). In that case, we held that a challenge asserting that the
    Commission considered evidence outside the scope of the rule (from a previous proceeding declared
    void) was a challenge to the application of the rule, not to the validity of the rule’s failure to mention
    the use of that evidence. 
    Id. at 360.
    Here, we have the converse; appellants challenge the validity
    of the rule through challenges to the application of the rule. While appellants state some issues
    asserting that the rule was applied in unexpected ways, some challenges at their core address the
    validity of terms of the rule. We conclude that the latter should have been brought by direct appeal.
    The district court’s decision that it lacks jurisdiction over validity challenges is based,
    not on res judicata, but on statutory limits on the time and place for validity challenges. Unlike the
    general statutes permitting declaratory judgments regarding the validity of rules and substantial-
    9
    evidence reviews, challenges to the validity of a competition rule must be brought by direct appeal
    to this Court not more than 15 days after the date on which the rule as adopted is published in the
    Texas Register. Compare Tex. Gov’t Code Ann. §§ 2001.038, .174, and PURA § 15.001, with
    PURA § 39.001(f). Appellants’ argument that section 39.001(e) requires that appeals be conducted
    under the APA does not prevail because the APA applies “unless otherwise provided”; the time and
    venue limitation of section 39.001(f) provides otherwise. See PURA § 39.001. This specific statute
    controls over the more general permission of validity challenges through declaratory-judgment
    actions. See Columbia Hosp. Corp. v. Moore, 
    92 S.W.3d 470
    , 473 (Tex. 2002); Lufkin v. City of
    Galveston, 
    63 Tex. 437
    , 439 (1885). Section 39.001(f) is unchallenged, mandatory, and exclusive.
    Under the plain language of section 39.001(f), the district court had no jurisdiction over validity
    challenges, which must have been brought by direct appeal to this Court within 15 days after the
    adopted rule was published. See 
    id. The statute
    does not provide that persons challenging the
    validity of a rule may wait until the rule is applied to them before challenging the validity of its terms
    under another provision. See 
    id. While some
    persons may be bound before they are aware of the
    formulation of competition rules and the need to challenge them, we need not consider that issue
    because there is no indication in the record that we face that situation here.
    Dismissal of validity challenges in this case should not create a torrent of validity
    challenges because of the specific limitation of the rule to competition rules. See § 39.001(f). The
    legislature determines the scope of our jurisdiction and that of district courts. Tex. Const. art. V,
    §§ 6, 8; see also Tex. Gov’t Code Ann. §§ 22.220, 24.007 (West 2004). PURA requires that
    challenges to the validity of competition rules be brought directly and quickly in this Court. See
    10
    PURA § 39.001(f). Although we may read the scope of challenges to validity narrowly, we cannot
    ignore statutory mandates in hopes of avoiding an onslaught of preemptive validity challenges.
    Some of the challenges in this case are applicability challenges, some are validity
    challenges, and others straddle the line between the types. Rather than parsing the classifications
    at the outset, we will address the merits of challenges to the application of the rule, and dismiss those
    addressed to rulemaking that are not properly before us.
    SUBSTANTIVE CHALLENGES
    For the permissible challenges to the application of the statute and rule, we review
    the Commission’s actions under the substantial-evidence standard, which provides as follows:
    If the law authorizes review of a decision in a contested case under the substantial
    evidence rule or if the law does not define the scope of judicial review, a court may
    not substitute its judgment for the judgment of the state agency on the weight of the
    evidence on questions committed to agency discretion but:
    (1) may affirm the agency decision in whole or in part; and
    (2) shall reverse or remand the case for further proceedings if substantial rights of
    the appellant have been prejudiced because the administrative findings,
    inferences, conclusions, or decisions are:
    (A) in violation of a constitutional or statutory provision;
    (B) in excess of the agency’s statutory authority;
    (C) made through unlawful procedure;
    (D) affected by other error of law;
    (E) not reasonably supported by substantial evidence considering the reliable
    and probative evidence in the record as a whole; or
    11
    (F) arbitrary or capricious or characterized by abuse of discretion or clearly
    unwarranted exercise of discretion.
    Tex. Gov’t Code Ann. § 2001.174.
    When construing a statute, we must try to interpret the statute in a way that gives
    effect to the plain meaning of the statute’s words and effectuates the legislature’s intent. Tex. Gov’t
    Code Ann. §§ 312.003, .005 (West 1998); State v. Gonzalez, 
    82 S.W.3d 322
    , 327 (Tex. 2002).
    Statutory construction is a question of law that we review de novo. 
    Id. We are
    not bound by an
    agency’s interpretation of a statute that it administers or enforces. Rylander v. Fisher Controls Int’l,
    Inc., 
    45 S.W.3d 291
    , 299 (Tex. App.—Austin 2001, no pet.). The supreme court summarized the
    process as follows:
    We look first to the “plain and common meaning of the statute’s words.” Fitzgerald
    v. Advanced Spine Fixation Sys., Inc., 
    996 S.W.2d 864
    , 865 (Tex. 1999) (quoting
    Liberty Mut. Ins. Co. v. Garrison Contractors, Inc., 
    966 S.W.2d 482
    , 484 (Tex.
    1998)). If a statute’s meaning is unambiguous, we generally interpret the statute
    according to its plain meaning. 
    Fitzgerald, 996 S.W.2d at 865
    . Moreover, we
    determine legislative intent from the entire act and not just from isolated portions.
    Jones v. Fowler, 
    969 S.W.2d 429
    , 432 (Tex. 1998). Thus, we “read the statute as a
    whole and interpret it to give effect to every part.” 
    Jones, 969 S.W.2d at 432
    .
    
    Gonzales, 82 S.W.3d at 327
    . Regardless of whether the statute is ambiguous, we may consider,
    among other matters, the object sought to be attained, the circumstances under which the statute was
    enacted, the legislative history, the common law or former statutory provisions, including laws on
    the same or similar subjects, the consequences of a particular construction, the administrative
    construction of the statute, and the title (caption), preamble, and emergency provision. Tex. Gov’t
    Code Ann. § 311.023 (West 1998).
    12
    Generally, we construe agency rules in the same manner as statutes, striving to give
    effect to the agency’s intent and following the plain language of the rule unless it is ambiguous.
    Rodriguez v. Service Lloyds Ins. Co., 
    997 S.W.2d 248
    , 254 (Tex. 1999). But if there is vagueness,
    ambiguity, or room for policy determinations in the regulation, we will defer to the agency’s
    interpretation unless it is plainly erroneous or inconsistent with the language of the rule. H.G.
    Sledge, Inc. v. Prospective Inv. & Trading Co., 
    36 S.W.3d 597
    , 604 (Tex. App.—Austin 2000, pet.
    denied). The agency’s interpretation of its rule represents the view of the regulatory body that
    drafted and administers the rule and essentially becomes a part of the rule itself. 
    Id. Although the
    agency’s interpretation of a statute is entitled to respect and weight, it does not bind us. Fisher
    
    Controls, 45 S.W.3d at 299
    .
    Proof of entitlement to increase fuel factor
    Appellants raise several challenges to the nature and sufficiency of the evidence
    considered by the Commission when increasing First Choice’s fuel factor. They contend that the
    Commission violated its statutory authority by increasing the fuel factor (1) while not requiring First
    Choice to present necessary evidence, (2) allowing First Choice to present irrelevant evidence, and
    (3) barring appellants from presenting relevant evidence. Appellants contend that the evidence
    considered does not satisfy the statute or the rule.
    Appellants argue that the Commission exceeded its authority and rendered portions
    of PURA section 39.202(l) and rule 25.41 meaningless by adjusting First Choice’s fuel factor based
    only on a showing of a minimum 4% change in the NYMEX index. They correctly note that the
    statute does not refer to the NYMEX index and argue that the rule only uses the NYMEX index as
    13
    the mechanism by which the adjustment is calculated once the need for an adjustment is otherwise
    proved. They assert that there must be, in addition to proof of a 4% change in the NYMEX index,
    proof of the market price of gas and energy used to serve retail customers, proof of significant
    change in that price, and proof that the existing fuel factor does not adequately reflect that significant
    change. They complain that the record lacks evidence linking the NYMEX index, the price that First
    Choice paid for such gas and energy, and the market price of gas and energy actually used to serve
    retail customers. They contend that the Commission contravened PURA § 39.202(l) when it failed
    to determine whether the market prices of natural gas and purchased energy embedded in First
    Choice’s purchased power contracts had significantly increased. Because the index is the only
    evidence First Choice offered to support an adjustment of its fuel factor, appellants contend that First
    Choice supplied no evidence to support the fuel-factor increase; accordingly, they assert that the
    Commission exceeded its authority by adjusting the fuel factor based solely on the increase in the
    NYMEX index.
    1. Use of the NYMEX index
    Resolution of many of appellants’ issues turns on the extent of the use of the NYMEX
    index permitted by statute and rule. Neither the statute nor the rule specifies how a provider must,
    or must not, demonstrate change to the relevant market price or the fuel factor’s inadequacy to reflect
    that change. See PURA § 39.202(l); rule 25.41(g)(1). The express language of rule 25.41 authorizes
    the NYMEX index as the means to calculate the remedy for inadequacies in the fuel factor and sets
    4% as the minimum level of change in the NYMEX index to permit adjusting the fuel factor. See
    rule 25.41(g)(1)(A)-(D). But both the rule and the Commission’s discussion of it indicate that the
    14
    NYMEX index will be used to assess the adequacy of the fuel factor to reflect significant changes
    in the market price of gas and purchased energy used to serve retail customers.
    Appellants argue that the demonstration of the inadequacy of the fuel factor is a
    bifurcated process requiring separate determinations of the adequacy of the fuel factor and the
    adjustment of the fuel factor. They rely on the fact that the first sentence of the rule restates the
    statute’s outline of the assessment process and only the subsections detailing the adjustment
    mechanism mention the NYMEX index. See rule 25.41(g)(1). Although it is possible to extrapolate
    from this structure the idea that the assessment and the adjustment are separate analyses, that
    extrapolation is not required and that idea is not consistent with the Commission’s discussion
    contemporaneous with the adoption of the rule or with the rule’s implementation. Appellants’
    bifurcation of the analysis would permit a finding of a significant change that fails to meet the 4%
    threshold, while a unitary process defines a 4% change as “significant” and adjusts the fuel factor
    upon a showing of that change. The less strained reading is that the comparison of the current
    NYMEX index with the index supporting the existing fuel factor, coupled with the 4% threshold,
    is the analysis for the significance of the change in the market price and of the adequacy of the fuel
    factor to reflect that change.
    Whether the NYMEX index reflects the market price of natural gas and purchased
    energy used to serve retail customers concerns the validity of the rule. The Commission explained
    in the 2001 rulemaking proceeding that the NYMEX index is evidence of the market price of natural
    gas and purchased energy—regardless of the generation source of that electricity—used to serve
    retail customers. See 26 Tex. Reg. at 2692-94. The Commission noted “the undeniable fact that
    15
    REPs, affiliated or not, will not incur costs after 2002 based on a historic fuel mix; rather, all REPs
    will be purchasing power in the market.” 
    Id. at 2692.
    Purchases by REPs are, by definition, made
    to supply electric energy “to retail customers.” See PURA § 31.002(17) (retail electric providers
    supply electric energy to retail customers). The Commission also stated, “Beyond 2002, the market
    price of generation will likely be set by gas-fired generation, and as such, it is appropriate to apply
    the changes in the market price of natural gas and purchased energy to the entire fuel factor in order
    to maintain the level of headroom in the price-to-beat.” 
    Id. at 2693.
    The Commission emphasized
    its intent to rely on market indices by providing for the use of an electricity commodity index after
    a sufficiently liquid one developed. 
    Id. at 2693.
    Although commenters expressed concerns about
    the adequacy and reliability of the NYMEX index to represent the relevant market price (see, e.g.,
    26 Tex. Reg. at 2682, 84, 91), the Commission rejected those concerns by adopting the NYMEX
    index as the sole measure of the market price. Thus, the Commission concluded that the NYMEX
    index represents the market price of natural gas and purchased energy used to serve retail customers.
    The Commission also determined in the 2001 rulemaking proceeding that a change
    in the NYMEX index represents the requisite significant change in the market price. The
    Commission described the 4% change in the NYMEX index as the “materiality threshold” for
    changes in the index to show the statutorily required “significant changes” in market prices and
    therefore support adjustment of the fuel factor.7 See 26 Tex. Reg. at 2694. The Commission thus
    7
    The Commission wrote:
    Based on the comments received, the commission concludes that a 4.0%
    materiality threshold is reasonable. The commission disagrees with those
    commenters suggesting that there be no materiality threshold. PURA §39.202(l)
    16
    linked the measurement of the adequacy of the fuel factor to reflect significant changes in market
    price and the mechanism to correct inadequacies, and concluded that the NYMEX index was
    sufficient for both tasks. The Commission has implemented the rule consistent with its discussion.
    Although the amended rule is not before us, the Commission confirmed its adoption
    of the NYMEX index for these purposes in the 2003 rulemaking proceeding amending rule 25.41.
    2003 Rulemaking 
    Case, 131 S.W.3d at 319
    . Because the Commission did not waver in its devotion
    to the NYMEX index, the arguments pertaining to the use of market price in that proceeding are
    instructive and persuasive regarding the Commission’s interpretation of the enabling statute and the
    extent of the use of the NYMEX index under rule 25.41. See 
    id. at 322-23.
    The 2003 amendments
    mainly concerned the threshold amount of change in the NYMEX index and the length of the period
    measured to evaluate the market price. 
    Id. at 319;
    see also 28 Tex. Reg. 3249 (2003). The
    Commission concluded that the statute’s reference to “market price” required use of a market index,
    and also concluded that the NYMEX index was sufficiently correlated to the market price of both
    specifies that PTB fuel factors may be adjusted for ‘significant changes in the
    market price of natural gas and purchased energy . . . .’ (emphasis added). Use
    of the term ‘significant’ indicates that some sort of threshold be demonstrated in
    order to justify an adjustment under § 39.202(l). . . .
    The commission concludes that a 4.0% materiality threshold is reasonable
    because such a threshold is analagous [sic] to the existing materiality threshold
    in the current fuel rule. While the commission recognizes that the current 4.0%
    threshold is based on the current solid fuel and gas mix of the integrated utility,
    in a competitive market, the market clearing price of purchased power will be set
    by the marginal unit in the market, which will most likely be a combined-cycle
    gas turbine.

    natural gas and of purchased energy used to serve retail customers. See 2003 Rulemaking 
    Case, 131 S.W.3d at 323
    (citing 28 Tex. Reg.at 3261-63); see also PURA § 39.202(l). The Commission
    rejected use of AREPs’ actual costs, stating that “[b]asing price-to-beat fuel factor adjustments solely
    on the actual costs of the affiliated REP and not the market price of natural gas and purchased energy
    (as required by statute) will ignore the market prices that non-affiliated REPS must incur to compete
    against the affiliated REP.” 2003 Rulemaking 
    Case, 131 S.W.3d at 323
    (quoting 28 Tex. Reg. at
    3261).
    Appellants further complain that the Commission misapplied its own rule by making
    the adjustment automatic upon the finding of an index increase of more than 4%. The rule provides
    that, upon a showing that the index has changed by 4% or more, the Commission “may” adjust the
    fuel factor. Although the rule does not mandate a change on that showing, neither does it require
    an additional showing. If the index shows that the market price has changed and the fuel factor has
    not changed, it is logical under the Commission’s reasoning to conclude that the fuel factor does not
    reflect the changed market price. Further, there is no finding or conclusion that the change is
    automatic, only that the Commission has determined that a 4% change in the NYMEX index
    satisfies the statutory requirement of a significant change. We decline to read the preamble of the
    rule and the statute to require showings additional to the 4% change in the NYMEX index average
    found sufficient by the Commission to satisfy both the statute and the rule.
    The suitability of the NYMEX index to measure the relevant market price was
    decided in the rulemaking proceeding, and we cannot review it in this ratemaking proceeding. The
    Commission’s determination in the rulemaking proceeding to use the NYMEX index as the sole
    18
    means to correct inadequacies in the fuel factor, combined with its linkage between the
    determination of adequacy and the correction of inadequacies, supports the Commission’s use in this
    proceeding of the NYMEX index as the sole measure of the adequacy of the fuel factor.8 The
    absence of any reference to the NYMEX index in the statute does not prohibit the Commission from
    using it for these purposes, and that use does not render the statute or the rule meaningless in whole
    or in part. Although the Commission could have chosen other methods either to assess the adequacy
    of the fuel factor or to adjust it—i.e., looking to the AREP’s actual costs, as appellants urge—we
    find no support for the argument that exclusive use of the NYMEX index to assess the adequacy of
    the fuel factor violates either the statute or the rule in a way subject to attack in this ratemaking
    proceeding. The Commission explained in the rulemaking proceeding why use of the AREP’s actual
    costs was not only inappropriate but also contrary to the intent of the transitional statutes. The
    Commission’s choice of the NYMEX index was unchallenged by direct appeal and reinforced in the
    2003 amendment process. Therefore, this suit for judicial review of the ratemaking decision did not
    invoke the district court’s jurisdiction to review the adoption of the NYMEX index-dependent
    method. The challenges to the application of the rule and statute in this regard likewise lack merit.
    2. Admissibility and sufficiency of evidence about adequacy of fuel factor
    Appellants complain about the type and sufficiency of the evidence admitted at the
    ratemaking hearing. Appellants decry the exclusion of their evidence regarding the prices actually
    8
    We reached a similar conclusion based on additional testimony regarding the 2003
    amendments to rule 25.41, which retained use of the NYMEX index but adjusted the materiality
    threshold and the measuring period. See generally, 2003 Rulemaking 
    Case, 131 S.W.3d at 322-23
    .
    19
    paid by First Choice for natural gas or purchased energy used to serve retail customers. They assert
    that First Choice’s evidence of NYMEX index rates is no evidence of the adequacy of the fuel factor
    to reflect significant changes in the market price of natural gas and purchased energy used to serve
    retail customers, and thus that First Choice failed to produce necessary evidence. They contend that
    evidence of the NYMEX index alone cannot satisfy various elements of the statute and rule. They
    contend that there was no evidence that First Choice would suffer losses if the Commission did not
    increase its fuel factor. They also contend that the increase of First Choice’s fuel factor based on
    such limited evidence contravenes legislative intent for the price-to-beat.
    Appellants argue that, by not requiring the AREPs to provide evidence of the actual
    prices paid for gas and energy “used to serve retail customers,” the Commission has written words
    out of the statute. But the statute does not require “actual” prices paid, nor does it require the prices
    paid by an individual AREP; instead, it mandates that the “market” price is the standard to be used.
    The Commission decided within its authority that the relevant market price was the price that a new
    REP would have to pay to serve retail customers as reflected by the NYMEX index, not the price
    paid by First Choice or other AREPs.9 As discussed above, the Commission determined in the
    rulemaking proceedings that the natural gas price drives the market price of purchased energy.10 See
    9
    In our opinion on amended rule 25.41, we discussed the Commission’s theory that the use
    of current market prices, regardless of the price actually paid by affiliated retail electric providers
    under possibly lower long-term contracts, would further its goal of enabling and encouraging
    competitive electric providers to enter the market. 2003 Rulemaking 
    Case, 131 S.W.3d at 322-25
    .
    10
    Appellants correctly point out that the district court inaccurately states in Conclusion of
    Law #7 that PURA section 39.202(l) looks “only to the market price of natural gas and purchased
    energy as determined by the NYMEX Henry Hub index.” (Emphasis added.) The statute does not
    refer to the NYMEX index. However, because the conclusion of law is also accurately based on rule
    25.41, the stray language in that conclusion regarding the statute did not harm appellants.
    20
    26 Tex. Reg. at 2694-95. Because that is the market in which REPs, companies that serve retail
    customers, purchase energy or gas, the NYMEX index is evidence of the price of gas and energy
    used to serve retail customers. Comparison of the current index to the index used to set the existing
    fuel factor is evidence of whether that market price has changed. Comparison of the rate of change
    to the 4% materiality threshold determines whether any change is statutorily significant. Under the
    rule as adopted in 2001, the NYMEX index is not irrelevant, is not just some evidence, but is
    conclusive evidence of the elements of the statute and the rule.
    Accordingly, the Commission did not err by excluding evidence of prices actually
    paid for gas and energy, nor did it err by “ignoring” unrebutted evidence that the fuel-factor
    adjustment would lead to a windfall profit for First Choice. The Commission follows the rules of
    evidence applicable in civil cases. 16 Tex. Admin. Code § 22.221 (2004). “Irrelevant, immaterial,
    or unduly repetitious evidence shall be excluded.” 
    Id. Evidence is
    relevant if it has any tendency
    to make the existence of any fact that is of consequence to the determination of the action more
    probable or less probable than it would be without the evidence. Tex. R. Evid. 401. Evidence
    regarding First Choice’s purchase price and any windfall profits resulting from the fuel-factor
    adjustment does not bear on whether the NYMEX index has changed the requisite amount. The
    Commission did not err by excluding or refusing to consider such evidence.
    Appellants’ arguments that the Commission’s actions contravene legislative history
    are not persuasive. Appellants contend that the legislature made the fuel factor adjustable in order
    to keep the price-to-beat from falling significantly below market so that competitors could enter the
    market, to provide a safe harbor for customers to receive service from their familiar suppliers at
    21
    regulated rates 6% lower than rates in effect before the transition began, and to protect providers
    from uncompensated losses.11         The intent to develop a competitive market supports the
    Commission’s action. The 6% price break was guaranteed only at the beginning of the period; the
    statute sets no upward limit on the price-to-beat due to fuel-factor adjustments. See PURA
    § 39.202(a), (l). The Commission determined that maintaining the price-to-beat at below-market
    levels would hinder the legislature’s goal to have competitors enter the market. 26 Tex. Reg. at
    2680, 92. While the Commission may have been concerned that setting too high a minimum change
    in the NYMEX index could inflict losses on AREPs, neither the statute nor the rule confines the fuel-
    factor’s adjustability to loss prevention. Even if a price rise is not necessary to prevent losses, the
    Commission is within its discretion to determine that achievement of the legislature’s express policy
    goal to foster competition (see PURA § 39.001(a)) outweighs other concerns. If, as appellants urge,
    11
    Appellants cite both case law and legislative history. See Reliant Energy, Inc. v. Public
    Util. Comm’n, 
    62 S.W.3d 833
    , 838 (Tex. App.—Austin 2001, no pet.); see also Public Utility
    Regulatory Act: Hearings on S.B. 7 Before the Senate Spec. Comm. on Elec. Util. Restructuring,
    76th Leg., R.S. at 18 (March 1, 1999). Appellants’ arguments echo comments in the rulemaking
    proceeding before the Commission:
    OPC explained that the legislative policy for the price to beat is to provide a
    safe haven for residential and small commercial customers from any adverse
    impacts of competition that might arise during the transition period. The use of
    a fuel factor mechanism for adjustments, OPC explained, indicates that PTB
    customers would not face any consequences greater than under a regulated cost
    of service rate. OPC reasoned that the Legislature was aware that this provision
    placed risks on the affiliated REP, which no longer owned generation. OPC
    contended that the affiliated REP is required to absorb that risk unless it
    becomes so onerous that an adjustment to the PTB needs to be requested on
    financial integrity grounds.
    26 Tex. Reg. at 2692.
    22
    the Commission misinterpreted legislative intent in promulgating the rule in 2001 and applying it
    in this case in 2002, the legislature had ample opportunity during its regular session in 2003 and four
    subsequent special sessions to clarify its intent. Although the legislature’s silence is far from
    dispositive,12 its silence on this issue is significant.
    The Commission decided in the rulemaking proceeding that it would adjust an
    AREP’s fuel-factor based on evidence of sufficient change in the NYMEX index over a specified
    period. The Commission indicated in the rulemaking proceeding, and confirmed in this adjustment
    proceeding, that the NYMEX index data alone would support the adjustment. There is no dispute
    that First Choice provided the NYMEX-derived data supporting a fuel-factor adjustment. The
    Commission did not err by excluding or failing to consider other evidence—even evidence of
    windfall profits that the Commission found “troubling.” The Commission made findings and
    conclusions regarding what evidence was necessary under the rule and the statute to justify an
    increase in the fuel factor, and concluded that First Choice had supplied the necessary evidence. We
    conclude that sufficient evidence supports those findings and conclusions.
    3. Allowability of size of increase of price-to-beat
    Appellants argue that the fuel-factor increase violates a set limit on the price-to-beat.
    See PURA § 39.202(p). That section provides:
    12
    “It is at best treacherous to find in congressional silence alone the adoption of a controlling
    rule of law.” Girouard v. United States, 
    328 U.S. 61
    , 69 (1946), quoted in Boys Markets, Inc. v.
    Retail Clerks Union, Local 770, 
    398 U.S. 235
    , 241 (1970).
    23
    On finding that a retail electric provider will be unable to maintain its financial
    integrity if it complies with Subsection (a), the commission shall set the retail electric
    provider’s price-to-beat at the minimum level that will allow the retail electric
    provider to maintain its financial integrity. However, in no event shall the price-to-
    beat exceed the level of rates, on a bundled basis, charged by the affiliated electric
    utility on September 1, 1999, adjusted for fuel as provided by Subsection (b).
    
    Id. Appellants argue
    that the phrase “in no event” means that the price-to-beat can never exceed the
    September 1, 1999 rate (“the 1999 rate”) and that application of the statute is not limited to situations
    in which the provider’s financial integrity is threatened. They assert without contradiction that the
    fuel-factor adjustment in this case causes First Choice’s price-to-beat to exceed its 1999 rate.
    The Commission argues that the adjustment in subsection (p) relates only to the initial
    setting of the price-to-beat. Subsection (p) refers to hardships imposed by compliance with
    subsection (a), which defines the price-to-beat and its period of applicability:
    (a) From January 1, 2002, until January 1, 2007, an affiliated retail electric provider
    shall make available to residential and small commercial customers of its
    affiliated transmission and distribution utility rates that, on a bundled basis, are
    six percent less than the affiliated electric utility’s corresponding average
    residential and small commercial rates, on a bundled basis, that were in effect
    on January 1, 1999, adjusted to reflect the fuel factor determined as provided by
    Subsection (b) and adjusted for any base rate reduction as stipulated to by an
    electric utility in a proceeding for which a final order had not been issued by
    January 1, 1999. These rates on a bundled basis shall be known as the “price-to-
    beat” for residential and small commercial customers, except that the “price-to-
    beat” for a utility is the rate in effect as a result of a settlement approved by the
    commission after January 1, 1999, if the commission determines that base rates
    for that utility have been reduced by more than 12 percent as a result of a final
    order issued by the commission after October 1, 1998.
    (b) The commission shall determine the fuel factor for each electric utility as of
    December 31, 2001.
    PURA § 39.202.
    24
    We conclude that subsection (p) does not prevent the price-to-beat from rising above
    the 1999 rates due to fuel-factor adjustments under subsection (l). Subsection (p) expressly applies
    only when the Commission finds that the provider will be unable to maintain its financial integrity
    if it complies with subsection (a). The “in no event” language applies to that situation alone; i.e.,
    regardless of the threat to financial integrity, the rate cannot exceed the 1999 price. The interaction
    of other provisions supports this constraint on the reach of subsection (p). Subsection (a) establishes
    the price-to-beat at a rate 6% below the rate charged on January 1, 1999, modified by the fuel factor
    determined under subsection (b). See 
    id. § 39.202.
    Subsection (b) concerns only the initial setting
    of the fuel factor on December 31, 2001. The specificity of subsection (b) ties these interconnected
    subsections to the outset of the transition period. By contrast, the twice-yearly adjustments permitted
    under subsection (l) are not mentioned by subsection (p); we conclude that the adjustments under
    subsection (l) are not limited by subsection (p). Consumers get an initial price break of up to 6%,
    but adjustments due to increases in the market price of gas and energy can thereafter drive the price-
    to-beat higher.
    Even if subsection (p) applied through the entire transition period, its express terms
    limit its application to adjustments to the price-to-beat based on preservation of financial integrity
    as described in the first sentence of subsection (p). Reading it to limit adjustments based on market
    price under subsection (l) would cap the price-to-beat for several years regardless of energy prices,
    rendering the fuel-factor adjustment provisions of subsection (l) essentially nugatory in an
    inflationary energy market and preventing providers from recovering their fuel costs.              The
    Commission’s interpretation implements the legislature’s balance between protecting consumers and
    fostering competition.
    25
    As the State’s policy changes from regulation to competition in the provision of
    electricity, so too must the measures taken to protect the customers. The legislature has placed its
    faith in market forces to ultimately provide price control. The Commission’s implementation of its
    rules, while a departure from historical procedure, is within the bounds of legislative directives and
    the Commission’s rules.
    45-day time limit
    Appellants complain that the 45-day timeline for the fuel-factor adjustment process
    is far too short. They contend that it prevents them from mustering evidence and having a
    meaningful hearing. They argue that the timeline is unprecedented for a contested case and is driven
    by the Commission’s desire to have an uncontested process.
    This is primarily a challenge to the rule that would have been appropriate in the
    rulemaking proceeding. When these arguments were raised regarding the amended rule, this Court
    was not persuaded and concluded that the Commission had acted within its authority in adopting the
    45-day timeline. 2003 Rulemaking 
    Case, 131 S.W.3d at 325-26
    . This Court held that the 45-day
    timeline satisfied the Administrative Procedures Act, that the relatively short period helped provide
    market certainty and responsiveness to market shifts, and that the process of evaluating changes in
    the NYMEX index was so straightforward that it did not require extensive preparation or lengthy
    hearings. 
    Id. at 326.
    This Court declined to rule out the possibility that a particular entity might be
    able to show a deprivation of due process in a particular case.
    Appellants do not show that the application of this rule has deprived them of due
    process. They argue that they were prevented from developing and presenting evidence, but their
    26
    complaints concern evidence of First Choice’s actual costs and other factors beyond the NYMEX
    index, all of which the Commission deemed irrelevant. They do not argue that the time limit
    prevented them from mustering evidence pertaining directly to changes in the NYMEX index itself.
    Because we have found no error in the exclusion of evidence not pertaining to the change in the
    NYMEX index, we find no deprivation of due process if the 45-day time period prevented
    development of any such evidence deemed irrelevant under the statutory and regulatory scheme.
    Failure to require reimbursement of cities’ rate-case expenses
    Appellants complain that the Commission violated statutory authority and agency
    precedent by failing to require First Choice to reimburse the cities for reasonable expenses incurred
    in this proceeding. The relevant statute provides:
    (a) The governing body of a municipality participating in or conducting a
    ratemaking proceeding may engage rate consultants, accountants, auditors,
    attorneys, and engineers to:
    (1) conduct investigations, present evidence, and advise and represent the
    governing body; and
    (2) assist the governing body with litigation in an electric utility ratemaking
    proceeding before the governing body, a regulatory authority, or a court.
    (b) The electric utility in the ratemaking proceeding shall reimburse the governing
    body of the municipality for the reasonable cost of the services of a person
    engaged under Subsection (a) to the extent the applicable regulatory authority
    determines is reasonable.
    PURA § 33.023. Appellants argued, and the ALJ found, that this is a ratemaking case and, for
    purposes of ratemaking reimbursement, the Commission can require an AREP to “assume the role
    27
    of an electric utility.” The ALJ opined that requiring reimbursement of the cities’ expenses promotes
    the goal of encouraging municipalities to participate in ratemaking proceedings.
    The Commission acknowledged the policy concerns favoring reimbursement, but
    concluded that the statutory exclusion of “retail electric provider” from the definition of “electric
    utility” bars application of the responsibilities of an electric utility on First Choice, which is an
    affiliated retail electric provider. See PURA § 31.002(6)(H) (“‘Electric utility’ . . . does not include
    . . . a retail electric provider . . . .”). Although the statute separately defines AREPs (id. § 31.002(2))
    and retail electric providers (id. § 31.002(17)), it defines AREPs as a subset of retail electric
    providers. 
    Id. § 31.002(2)
    (“‘Affiliated retail electric provider’ means a retail electric provider that
    is affiliated with or the successor in interest of an electric utility certificated to serve an area.”).
    Appellants contend that the reimbursement requirement applies to AREPs. They
    contend that the fuel-factor adjustments are ratemaking proceedings and that AREPs are electric
    utilities for the purpose of these proceedings. They assert without contradiction that the fuel-factor
    adjustment is within the definition of a ratemaking proceeding. See Southwestern Pub. Serv. Co. v.
    Public Util. Comm’n, 
    962 S.W.2d 207
    , 218-19 (Tex. App.—Austin 1998, pet. denied) (because fuel
    cost reconciliation proceedings change rates, they are ratemaking proceedings and therefore require
    reimbursement of municipalities’ costs). However, First Choice and the Commission oppose the
    arguments that AREPs are utilities.
    Appellants cite statutes defining utilities as well as more general provisions to support
    their argument that AREPs are utilities for reimbursement purposes. They contend that the
    definitions in section 31.002 exclude only retail electric providers—not AREPs—from the definition
    of electric utility, and distinguish AREPs from retail electric providers. See 
    id. § 31.002(2),
    6(H),
    28
    (17). They contend that this distinction is real because AREPs remain under some regulation, while
    retail electric providers are not regulated. Appellants contend that the larger context of PURA
    supports treating the AREPs as utilities for this purpose. They cite the distinction between the
    AREPs’ “rates” (indicating regulation) and the “prices” to be determined by competition (indicating
    nonregulation) as showing that AREPs are more like regulated utilities than unregulated providers.
    Compare 
    id. § 39.202,
    with 
    id. § 39.001.
    They argue that the placement of the burden of proof in
    contested cases on the “incumbent electric utility” by PURA section 39.003 means that AREPs must
    be utilities because otherwise AREPs would not have the burden of proof in the fuel-factor
    adjustment cases like this one.
    We disagree. The plainest reading of the definitions is that, because AREPs are a
    subset of retail electric providers which expressly are not electric utilities, AREPs are not electric
    utilities. While AREPs may be regulated more than unaffiliated retail electric providers, appellants’
    argument that the general placement of the burden of proof on utilities requires that AREPs be
    treated as utilities is unpersuasive because the fuel-factor adjustment statute itself specifically places
    the burden of proof on AREPs. See 
    id. § 39.202(l).
    We conclude that First Choice is an AREP, not a utility, and that neither statutory
    law, case law, nor agency precedent requires First Choice to reimburse the cities’ costs on these
    facts.
    CONCLUSION
    Appellants brought many challenges to the Commission’s adjustment of First
    Choice’s fuel factor. The district court correctly concluded that it had no jurisdiction over challenges
    29
    to the validity of the rule because appellants did not comply with the time and venue requirements
    for such challenges. The district court correctly concluded that the remainder of the challenges were
    without merit, finding that the Commission acted within its authority by raising the fuel factor and
    by not ordering First Choice to reimburse the cities for their expenses. Because the Commission did
    not abuse its discretion, exceed its authority, act arbitrarily, or otherwise err in any way shown
    harmful to appellants, we affirm the district court’s judgment.
