    KING, Circuit Judge:
    In this appeal, plaintiff Old Dominion Electric Cooperative challenges the district
    court’s dismissal of its state law claims seeking nearly $15 million in damages from
    defendant PJM Interconnection, LLC. Following a severe cold weather outbreak in
    January 2014, Old Dominion unsuccessfully sought to recover certain electricity
    generation costs from PJM in an administrative proceeding before the Federal Energy
    Regulatory Commission (“FERC”). Old Dominion subsequently instituted the underlying
    litigation in Virginia state court, pursuing four putative state law claims against PJM which
    seek the same relief unsuccessfully claimed before FERC.
    PJM timely removed the state court proceedings to the Eastern District of Virginia,
    pursuant to 
    28 U.S.C. § 1441
    (a). PJM maintained therein that Old Dominion’s complaint
    contests electricity transmission rates set forth in PJM’s federally filed tariff and that the
    district court was vested with federal question jurisdiction under 
    28 U.S.C. § 1331
    . PJM
    promptly moved to dismiss the complaint for failure to state a claim, while Old Dominion
    moved for a remand to state court.
    On March 31, 2020, the district court denied Old Dominion’s remand motion and
    dismissed each of its claims with prejudice. See Old Dominion Elec. Coop. v. PJM
    Interconnection, LLC, No. 3:19-cv-00233 (E.D. Va. Mar. 31, 2020), ECF No. 26 (the
    “Dismissal Opinion”). In so ruling, the court determined that, consistent with our 2004
    decision in Bryan v. BellSouth Communications, Inc., 
    377 F.3d 424
     (4th Cir. 2004), Old
    Dominion’s putative state law claims effectively challenge the terms of PJM’s federal
    tariff. As such, and in accord with the principles enunciated by the Supreme Court in Gunn
    2
    v. Minton, 
    568 U.S. 251
     (2013), and Grable & Sons Metal Products, Inc. v. Darue
    Engineering & Manufacturing, 
    545 U.S. 308
     (2005), the court ruled that the claims present
    a substantial federal question. In granting PJM’s motion to dismiss, the court further
    resolved that the so-called “filed-rate doctrine” barred it from awarding damages on Old
    Dominion’s claims. On appeal, Old Dominion maintains that PJM’s tariff stands only as
    a defense to its putative state law claims and that the district court consequently lacked
    subject matter jurisdiction over those claims. As explained herein, Old Dominion’s
    contentions are unpersuasive and are rejected. We therefore affirm the judgment of the
    district court.
    I.
    A.
    Old Dominion is a nonprofit electric utility that serves customers in Virginia,
    Maryland, and Delaware. It generates and markets wholesale electric power, in part from
    the operation of three natural-gas-fired power plants in Virginia and Maryland. PJM, on
    the other hand, is not a utility but is instead a “regional transmission organization,” an
    entity that operates the electrical grid in a defined geographic area and in accord with
    extensive regulatory oversight by FERC. PJM is charged with supervising the transmission
    of electricity in its market region, which consists of 13 states and the District of Columbia.
    In fulfilling that responsibility, PJM controls the transmission facilities owned by its
    member utilities — including Old Dominion. See 
    18 C.F.R. § 35.34
    (j), (k).
    3
    PJM’s relationship with each of its member utilities is governed by FERC’s
    regulatory framework. The Federal Power Act vests FERC with exclusive regulatory
    authority over “the transmission of electric energy in interstate commerce and the sale of
    such energy at wholesale in interstate commerce,” directing FERC to ensure that all “rates
    and charges made, demanded, or received by any public utility for or in connection with
    the transmission or sale of electric energy” be “just and reasonable.” See 
    16 U.S.C. §§ 824
    (a), 824d(a). Accordingly, FERC requires regional transmission organizations like
    PJM to file schedules of proposed electricity transmission rates with the agency for its
    approval. Once authorized by FERC, those rates are set forth in tariffs, which “[c]arry the
    force of federal law,” in the same sense as ordinary federal regulations. See Bryan v.
    BellSouth Commc’ns, Inc., 
    377 F.3d 424
    , 429 (4th Cir. 2004). Further, under the regulatory
    rule known as the “filed-rate doctrine,” the transmission rates charged by utilities in
    association with the generation and sale of electric power may not be higher or lower than
    those set forth in FERC-approved tariffs. See Ark. La. Gas Co. v. Hall, 
    453 U.S. 571
    , 576
    (1981).
    PJM’s FERC-approved tariffs include (1) its Open Access Transmission Tariff (the
    “PJM Tariff,” or simply “the Tariff”) and (2) its Amended and Restated Operating
    Agreement (the “Operating Agreement”). The PJM Tariff prescribes rules controlling
    PJM’s management of the mid-Atlantic energy market and, as relevant in this appeal, fixes
    the price at which power generators may offer their energy production to PJM in standard
    4
    electricity auctions — specifically at $1000 per megawatt-hour. See J.A. 127. 1 The
    Operating Agreement, to which participating utilities like Old Dominion subscribe, reflects
    the terms of the Tariff. The Operating Agreement further affords PJM expansive powers
    to take “measures appropriate to alleviate an Emergency, in order to preserve reliability”
    in the electric market, principally by calling on its member utilities “to start, shutdown, or
    change output levels of [their] generation units” at any time. See Old Dominion Elec.
    Coop. v. FERC, 
    892 F.3d 1223
    , 1228 (D.C. Cir. 2018). As the relevant regulatory tariffs,
    the PJM Tariff and Operating Agreement together “conclusively and exclusively
    enumerate the rights and liabilities of the contracting parties.” See Marcus v. AT&T Corp.,
    
    138 F.3d 46
    , 56 (2d Cir. 1998) (internal quotation marks omitted). That is, all business
    that PJM conducts with electric utilities in its extensive market region must conform to the
    terms of its FERC-approved tariffs.
    The standards established and imposed by the PJM Tariff and Operating Agreement
    became particularly significant during the January 2014 “polar vortex,” a weather
    disturbance that brought uncharacteristically frigid temperatures to much of the eastern
    United States. See J.A. 25. The polar vortex prompted abrupt increases in consumer
    demand for electricity, which, in turn, required utilities and transmission organizations like
    Old Dominion and PJM to take swift actions to ensure that reliable supplies of power were
    available for use in heating homes and businesses. As temperatures plummeted, PJM
    1

    the parties in this appeal.
    5
    directed its member utilities to prepare for increases in their electric generation output.
    With respect to Old Dominion, PJM issued specific instructions for the utility to purchase
    sufficient quantities of natural gas to begin operating its Virginia and Maryland power
    plants at full capacity. Old Dominion maintains that — at that time — PJM also
    represented to Old Dominion’s agents that the company would “make [Old Dominion]
    whole for its fuel and other costs associated with purchasing the natural gas.” Id. at 26; see
    also Br. of Appellant 5.
    When PJM issued its directives to Old Dominion, the price of natural gas had spiked
    above its pre-polar vortex levels due to the weather-related strains on energy production
    resources. Once paired with the costs of operating the Virginia and Maryland facilities,
    the heightened gas purchase price forced Old Dominion’s net costs for electricity
    generation to approximately $1200 per megawatt-hour — well north of the $1000
    maximum rate fixed by the PJM Tariff. In compliance with PJM’s orders, Old Dominion
    nevertheless purchased the needed fuel at the inflated price. After it did so, however, PJM
    repeatedly cancelled its operation requests or scaled them back in duration because of
    overestimates of consumer demand for power. The weather-driven market conditions
    compelled Old Dominion to sell generation capacity to PJM at a substantial loss, and Old
    Dominion ultimately incurred an aggregate sum of $14,925,669.58 in costs that exceeded
    the rate that it could legally charge PJM under the Tariff. In the disputes that followed,
    neither party contested that those losses — sustained because Old Dominion’s sales
    exceeded PJM’s tariffed rate — were unrecoverable under the express terms of the Tariff.
    6
    B.
    Old Dominion first sought relief from the excess incurred costs by way of a June
    2014 administrative proceeding before FERC. See Old Dominion Elec. Coop., 
    151 FERC ¶ 61,207
     (2015). Relying on its facility operation expenses and the excessive costs of
    natural gas purchased but not burned, the utility petitioned FERC for the full amount of its
    excess costs and damages — again, $14,925,669.58. Old Dominion did not dispute that its
    January sales to PJM fell within the scope of the Tariff and Operating Agreement
    provisions that control the entities’ relationship.   Indeed, Old Dominion “repeatedly
    conceded” before FERC that the PJM Tariff “categorically precluded” the compensation it
    sought. See Old Dominion, 892 F.3d at 1231. Old Dominion nevertheless petitioned FERC
    for a retroactive waiver of the Tariff’s rate-cap provisions, relying on equitable
    considerations and PJM’s representations that it would “make [Old Dominion] whole” for
    the excessive costs it had incurred during the polar vortex emergency. See J.A. 26.
    PJM intervened in the proceeding and, in consideration of its desire to fairly
    compensate Old Dominion, actually supported the utility’s waiver request.             FERC
    nevertheless denied relief, concluding that the filed-rate doctrine and the corresponding
    rule against retroactive ratemaking — a rule that prohibits the agency from adjusting
    tariffed rates retroactively absent limited and inapplicable exceptions — prohibited
    granting any waiver of the PJM Tariff’s established rates. Old Dominion sought a
    rehearing of FERC’s denial order, but FERC also denied that request. See Old Dominion
    Elec. Coop., 
    154 FERC ¶ 61,155
     (2016). FERC explained that the above-mentioned
    equitable concerns did not grant it any authority to waive the filed-rate doctrine and that
    7
    doctrine’s bar on compensating Old Dominion above the Tariff’s $1000 rate cap.
    Additionally, the agency determined that no outside contract providing for recovery of the
    emergency-related losses had been made between the parties, and that, in any event, FERC-
    approved rates cannot be modified or superseded by way of informal private agreements.
    Although appellate relief was sought by Old Dominion in 2018, the D.C. Circuit
    denied its petition for review of FERC’s adverse decisions. In so ruling, the court of
    appeals observed that the “emphatic rules against retroactively changing filed rates”
    disarmed Old Dominion’s arguments supporting a waiver of the PJM Tariff’s rate cap. See
    Old Dominion, 892 F.3d at 1231. The court also approved of FERC’s determination that
    it lacked discretion to waive filed rates “for good cause or for any other equitable
    considerations.” Id. at 1230. Although Old Dominion sought review in the Supreme Court
    of the adverse ruling by the court of appeals, the Court promptly denied its petition for a
    writ of certiorari. See Old Dominion Elec. Coop. v. FERC, 
    139 S. Ct. 794
     (2019). 2
    2
    Old Dominion was not alone in its efforts to recover losses incurred during the
    polar vortex event. Other PJM member utilities were similarly faced with substantial
    excessive costs associated with PJM’s emergency procedures that, under the terms of the
    PJM Tariff, were not compensable. Duke Energy, for example, sought a waiver of PJM’s
    rate cap just as Old Dominion did. As in this case, FERC denied Duke’s waiver request
    and the D.C. Circuit affirmed FERC’s decision. See Duke Energy Corp., 
    151 FERC ¶ 61,206
     (2015); Duke Energy Corp. v. FERC, 
    892 F.3d 416
     (D.C. Cir. 2018).
    8
    C.
    On January 5, 2017, Old Dominion filed this civil action against PJM in the Henrico
    County Circuit Court in Virginia. 3 In alleging a breach of several purported private
    contracts, the operative Amended Complaint sets forth the same factual contentions at issue
    in the FERC proceedings, focusing on PJM’s “failed assurances” that the company would
    “make [Old Dominion] whole for its fuel and other costs” incurred in connection with the
    polar vortex event. See J.A. 26. The Amended Complaint alleges four discrete claims
    against PJM, each purportedly grounded in state law: two claims for breach of contract,
    one for unjust enrichment, and another for negligent misrepresentation. Those claims are
    alleged in the alternative, with each asserting that it entitles Old Dominion to damages in
    the sum of $14,925,669.58 — the precise amount Old Dominion sought in petitioning
    FERC for a waiver of the PJM Tariff’s rate cap. See 
    id. at 30-33
    . The Amended Complaint
    refers to the applicable Tariff only once, to allege that Old Dominion and PJM “entered
    into a transaction that was outside of the requirements . . . set forth in any tariff or other
    regulated PJM policy or process.” 
    Id. at 29
    .
    PJM removed Old Dominion’s state court lawsuit to the Eastern District of Virginia
    in April 2019. By its Notice of Removal, PJM maintained that, as required by 
    28 U.S.C. § 1441
    (a), the litigation could have been initiated in federal court, namely on grounds of
    3
    Old Dominion’s initial 2017 state court complaint in Henrico County was filed
    after the failure of the utility’s administrative pursuits before FERC, but prior to the 2018
    resolution of its appeal to the D.C. Circuit. The operative Amended Complaint was filed
    by Old Dominion in March 2019, shortly after the Supreme Court’s denial of certiorari in
    the FERC litigation.
    9
    federal question jurisdiction. More specifically, PJM asserted that Old Dominion’s state
    law tort and contract claims “arise under” federal law, as contemplated by 
    28 U.S.C. § 1331
    , because they (1) are completely preempted by federal law or, alternatively,
    (2) necessarily raise a substantial federal question by challenging the terms of an applicable
    federally filed tariff. PJM also moved to dismiss the entirety of the Amended Complaint
    for failure to state a claim, relying on the PJM Tariff and contending that Old Dominion’s
    demands for relief are barred by the filed-rate doctrine. Old Dominion opposed PJM’s
    motion to dismiss and moved for a remand to the Virginia state court, insisting that its
    claims do not fall within the scope of federal question jurisdiction because their allegations
    are entirely confined to violations of state law.
    By its Dismissal Opinion and Final Order of March 31, 2020, the district court
    denied Old Dominion’s motion to remand and granted PJM’s motion to dismiss the
    Amended Complaint. Addressing the question of subject matter jurisdiction, the Dismissal
    Opinion first explained that Old Dominion’s four claims could “arise under” federal law in
    either of two ways: under the “complete preemption” doctrine, or otherwise under the
    “substantial federal question” doctrine. See Dismissal Opinion 13. Finding the former to
    be inapplicable, the court concluded that, by effectively challenging the terms of the FERC-
    filed PJM Tariff, Old Dominion’s claims “necessarily raise” a substantial federal question.
    
    Id. at 27-28
    . Because it possessed subject matter jurisdiction over the claims, the court
    went on to conclude that the filed-rate doctrine proscribed it from awarding relief that
    would, in effect, alter the Tariff’s rate cap as applied to Old Dominion. Accordingly, the
    court dismissed with prejudice each of the four claims alleged in the Amended Complaint.
    10
    In its Dismissal Opinion, the district court focused its analysis on our decision in
    Bryan v. BellSouth Communications, Inc., 
    377 F.3d 424
     (4th Cir. 2004), which concerned
    the removal to federal court of a putative state law claim in North Carolina that challenged
    allegedly unfair telephone service rates charged by BellSouth. The rates charged by
    BellSouth and other telecommunications carriers were controlled by the Federal
    Communications Commission (the “FCC”) through filed tariffs. We concluded in Bryan
    that the plaintiff’s claim — which, by requesting damages, effectively sought a refund of
    some portion of BellSouth’s service rate and thereby contested the terms of the carrier’s
    federal tariff — necessarily presented a substantial question of federal law and ran afoul of
    the filed-rate doctrine. See 
    id. at 430-32
    . We recognized in Bryan that, because federal
    tariffs “are the law, not mere contracts,” suits that effectively challenge the substance of
    such tariffs “arise[] under federal law” and may be heard in federal court. 
    Id. at 429-30
    .
    The Dismissal Opinion deemed Bryan as controlling here, and further determined
    that exercising federal jurisdiction was appropriate under the Supreme Court’s Gunn-
    Grable framework, which must be employed in assessing whether a claim rooted in state
    law nonetheless poses a “substantial federal question.” See Gunn v. Minton, 
    568 U.S. 251
    ,
    258 (2013) (citing Grable & Sons Metal Prods., Inc. v. Darue Eng’g & Mfg., 
    545 U.S. 308
    ,
    313-14 (2005)). The district court thus ruled that, by demanding the same relief sought
    before FERC — relief unambiguously barred by the terms of the PJM Tariff — Old
    Dominion’s claims necessarily raise a substantial federal question suitable for adjudication
    in federal court. Old Dominion has timely noted this appeal from the dismissal of its claims
    with prejudice, and we possess jurisdiction pursuant to 
    28 U.S.C. § 1291
    .
    11
    II.
    We review de novo a district court’s determination that it possessed subject matter
    jurisdiction over a plaintiff’s claims. See Mulcahey v. Columbia Organic Chems. Co., 
    29 F.3d 148
    , 151 (4th Cir. 1994). PJM removed Old Dominion’s state court proceedings to
    the district court pursuant to 
    28 U.S.C. § 1441
    (a), which requires that a state case “be fit
    for federal adjudication at the time the removal petition is filed.” See Moffitt v. Residential
    Funding Co., 
    604 F.3d 156
    , 159 (4th Cir. 2010) (quoting Caterpillar Inc. v. Lewis, 
    519 U.S. 61
    , 73 (1996)). PJM’s Notice of Removal asserted that the district court possessed
    federal question jurisdiction over Old Dominion’s claims alleged in the Amended
    Complaint under 
    28 U.S.C. § 1331
    , which affords the federal courts jurisdiction over “civil
    actions arising under the Constitution, laws, or treaties of the United States.”
    In determining whether a claim “arises under” the laws of the United States, courts
    abide by the “well-pleaded complaint rule,” assessing whether the plaintiff’s cause of
    action — as stated on the face of the complaint — has some basis in federal law. See
    Merrell Dow Pharms. Inc. v. Thompson, 
    478 U.S. 804
    , 807-08 (1986). The “vast majority”
    of such claims are those directly created by federal law, and a defense or counterclaim that
    raises a federal question is not an adequate basis for § 1331 jurisdiction. See id. at 808
    (citing Louisville & Nashville R.R. v. Mottley, 
    211 U.S. 149
     (1908)). It follows that, as a
    general proposition, the plaintiff is the “master of the complaint” and may keep his
    complaint out of federal court simply by “eschewing claims based on federal law.” See
    Caterpillar Inc. v. Williams, 
    482 U.S. 386
    , 398-99 (1987). Under the corollary “artful
    pleading” doctrine, however, “a plaintiff may not defeat removal by omitting to plead
    12
    necessary federal questions in a complaint.” See Franchise Tax Bd. v. Constr. Laborers
    Vacation Tr., 
    463 U.S. 1
    , 22 (1983); see also Travelers Indem. Co. v. Sarkisian, 
    794 F.2d 754
    , 758 (2d Cir. 1986) (“[A] plaintiff may not defeat removal by clothing a federal claim
    in state garb, or, as it is said, by use of ‘artful pleading.’”).
    Claims for relief that are rooted in state law, then, may nevertheless “arise under”
    federal law and fall within the scope of federal question jurisdiction in one of two narrow
    instances. First, under the “complete preemption” doctrine, federal jurisdiction is proper
    under § 1331 “when Congress ‘so completely pre-empt[s] a particular area that any civil
    complaint raising th[e] select group of claims is necessarily federal in character.’” See
    Pinney v. Nokia, Inc., 
    402 F.3d 430
    , 449 (4th Cir. 2005) (quoting Metro. Life Ins. Co. v.
    Taylor, 
    481 U.S. 58
    , 63-64 (1987)). Second, federal question jurisdiction may be exercised
    “where the vindication of a right under state law necessarily turn[s] on some construction
    of federal law.” See Merrell Dow, 
    478 U.S. at 808-09
     (quoting Franchise Tax Bd., 
    463 U.S. at 9
    ). The “substantial federal question” doctrine, that is, operates to permit removal
    of a complaint from state court where “a plaintiff’s ability to establish the necessary
    elements of his state law claims must rise or fall on the resolution of a question of federal
    law.” See Pinney, 
    402 F.3d at 449
    . In these circumstances, because Old Dominion’s claims
    pose a substantial question of federal law, we need not decide whether the district court
    was vested with jurisdiction by way of complete preemption. 4
    4
    We observe, however, that the complete preemption doctrine is most likely
    inapplicable in this situation. The Supreme Court has explained that it is “reluctant” to
    find that federal law provides the exclusive cause of action in an area that is federally
    (Continued)
    13
    Although the substantial federal question doctrine has long been recognized in the
    federal courts, the Supreme Court brought clarity to what it called an “unruly doctrine”
    through the Gunn-Grable framework. 5 See Gunn v. Minton, 
    568 U.S. 251
    , 258 (2013)
    (citing Grable & Sons Metal Prods., Inc. v. Darue Eng’g & Mfg., 
    545 U.S. 308
    , 313-14
    (2005)). Gunn-Grable provides for a four-part test, explaining that
    federal jurisdiction over a state law claim will lie if a federal issue is:
    (1) necessarily raised, (2) actually disputed, (3) substantial, and (4) capable
    of resolution in federal court without disrupting the federal-state balance
    approved by Congress.
    
    Id.
     Since the Court’s decision in Gunn in 2013, that four-part test has been the principal
    means for assessing whether resolution of a state law claim requires consideration of
    federal law, such that federal question jurisdiction is appropriate. See, e.g., Pressl v.
    Appalachian Power Co., 
    842 F.3d 299
    , 303 (4th Cir. 2016).
    Several years before the Court’s creation of the Gunn-Grable test, our decision in
    Bryan described the substantial federal question doctrine as follows:
    regulated. See Metro. Life Ins. Co. v. Taylor, 
    481 U.S. 58
    , 65 (1987). Indeed, in our 2005
    decision in Lontz v. Tharp, we identified only three statutes to which the Court has applied
    the complete preemption doctrine — specifically, the Labor Management Relations Act,
    ERISA, and the National Bank Act. See 
    413 F.3d 435
    , 441 (4th Cir. 2005). Recognizing
    the doctrine’s historically sparse application, the Seventh Circuit has ruled that the Federal
    Power Act — the very statute affording FERC the rate-regulation authority at issue in this
    case — does not completely preempt associated state law claims. See Ne. Rural Elec.
    Membership Corp. v. Wabash Power Ass’n, Inc., 
    707 F.3d 883
    , 896 (7th Cir. 2013).
    5
    In Gunn, the Court expounded on the state of the substantial federal question
    doctrine by noting that while “outlining the contours” of the rule did not involve “paint[ing]
    on a blank canvas . . . the canvas looks like one that Jackson Pollock got to first.” See

    [W]hen, as here, state law creates the plaintiff’s cause of action, the lower
    federal courts possess jurisdiction to hear “only those cases in which a well-
    pleaded complaint establishes . . . that the plaintiff’s right to relief necessarily
    depends on resolution of a substantial question of federal law.”
    See 
    377 F.3d 424
    , 428-29 (4th Cir. 2004) (quoting Franchise Tax Bd., 
    463 U.S. at 27-28
    ).
    We ruled therein that a federally filed and approved regulatory tariff “carries the force of
    federal law” and that “a claim that seeks to alter the terms of the relationship . . . set forth
    in a filed tariff therefore presents a federal question.” Id. at 429. In similar fashion, a claim
    seeking to have a court fix a special, reasonable tariffed rate unique to the plaintiff
    “effectively challenges” the relevant filed tariff in contravention of the filed-rate doctrine
    and likewise raises a substantial federal question. Id. at 429-30. In such a situation, the
    filed-rate doctrine — which strictly directs that “the rate of the carrier duly filed is the only
    lawful charge,” and bars the courts from permitting such inequity among ratepayers —
    compels a dismissal of the plaintiff’s claim. Id. (quoting Louisville & Nashville R.R. v.
    Maxwell, 
    237 U.S. 94
    , 97 (1915)).
    III.
    On appeal, Old Dominion maintains that the district court did not possess federal
    question jurisdiction over its state law claims against PJM, and that the court’s dismissal
    of those claims was accordingly erroneous. More specifically, Old Dominion contends
    that the PJM Tariff is merely a defense to its state claims, rather than being integral to the
    claims’ demands for relief. In light of our Bryan decision and our application of the Gunn-
    Grable framework, however, we are satisfied that the district court possessed jurisdiction
    15
    under the substantial federal question doctrine. Consistent with Bryan, the Dismissal
    Opinion correctly determined that Old Dominion’s claims effectively challenge the terms
    of the PJM Tariff, and that, by extension, the filed-rate doctrine obliged the district court
    to dismiss the putative state claims in the Amended Complaint. We are satisfied that Bryan
    controls the resolution of this dispute because, as in that case, Old Dominion’s asserted
    right to relief necessitates recourse to the Tariff that controls the utility’s relationship with
    PJM, thereby presenting a substantial federal question.
    Nor are we persuaded that Bryan has somehow been weakened or undermined by
    subsequent decisions of this Court, or by the Supreme Court’s Gunn-Grable test. The
    Fourth Circuit decisions relied on by Old Dominion as having eroded Bryan’s rulings are
    entirely consistent with Bryan’s treatment of the substantial federal question doctrine. 6 The
    Gunn-Grable framework, meanwhile, is likewise consistent with Bryan’s standard, and our
    application of Gunn-Grable in this case counsels the same outcome as our application of
    Bryan. As such, we must affirm the district court’s ruling that it possessed subject matter
    jurisdiction. Consistent therewith, we also affirm the court’s dismissal with prejudice of
    Old Dominion’s Amended Complaint and its four claims.
    6
    We also observe that, even if Old Dominion had identified Fourth Circuit decisions
    that conflict with Bryan, a panel of this Court cannot circumscribe or undermine an earlier
    panel decision, pursuant to McMellon v. United States and its progeny. See 
    387 F.3d 329
    ,
    333 (4th Cir. 2004) (en banc) (“When published panel opinions are in direct conflict on a
    given issue, the earliest opinion controls, unless the prior opinion has been overruled by an
    intervening opinion from this court sitting en banc or the Supreme Court.”); see also United
    States v. Williams, 
    808 F.3d 253
    , 261 (4th Cir. 2015); Payne v. Taslimi, 
    998 F.3d 648
    , 654
    (4th Cir. 2021).
    
    16 A. 1
    .
    The crux of this appeal concerns the applicability of Bryan to the facts of this case
    and whether Old Dominion’s claims may fairly be said to necessarily raise a substantial
    federal question. PJM deems Bryan to be dispositive, while Old Dominion considers that
    decision to be watered down at best, if not impliedly overruled by the Supreme Court. As
    explained below, we agree with the district court that Bryan remains “binding case law,”
    is factually comparable to this case, and compels the decision we reach today. See
    Dismissal Opinion 21.
    The Bryan decision resolved a question concerning the removal to federal court of
    a North Carolina state law challenge to service rates charged by BellSouth, a major
    telecommunications firm later acquired by AT&T.         Seeking to represent a class of
    BellSouth customers, plaintiff Bryan alleged that the carrier’s “Federal Universal Service
    Charge,” a fee assessed to recoup BellSouth’s required payments to a federal
    telecommunications fund, was an excessive charge that contravened North Carolina’s
    unfair trade practices law. See 
    377 F.3d 424
    , 426 (4th Cir. 2004). BellSouth removed the
    state court litigation to the Middle District of North Carolina, contending that Bryan’s
    complaint necessarily raised federal legal questions. BellSouth explained that the fee
    contested by Bryan was definitively established alongside other service rates in its
    “Schedule of Charges,” a tariff filed with and approved by the FCC. 
    Id.
    Following BellSouth’s removal to federal court, plaintiff Bryan filed an amended
    complaint alleging three state law claims: (1) a claim alleging that BellSouth had engaged
    17
    in unfair trade practices by failing to disclose how it calculated the service fee and that the
    fee was in excess of what was paid into the federal fund; (2) an unjust enrichment claim,
    maintaining that the fee was excessive and unlawful; and (3) a claim alleging a breach of
    the covenant of good faith and fair dealing that stemmed from BellSouth’s charging an
    excessive fee. The amended complaint generally sought damages in excess of $10,000 for
    each member of the putative class. Bryan moved for a remand to state court, while
    BellSouth moved to dismiss the amended complaint pursuant to the filed-rate doctrine. In
    disposing of those motions, the district court first determined that removal was proper
    because the plaintiff directly alleged that the amount of the federally tariffed fee was
    excessive. The court then dismissed Bryan’s second and third claims, but remanded her
    first claim alleging unfair trade practices, ruling that the unfair trade practices claim did
    not present a federal question. BellSouth appealed the order remanding and denying
    dismissal of that claim, maintaining that it also challenged the FCC tariff and therefore
    arose under federal law.
    On appeal, we vacated and remanded. Our decision concluded that the unfair trade
    practices claim “effectively challenge[d]” BellSouth’s filed rate, that it therefore presented
    a federal question, and that the district court erred in remanding the claim and should have
    dismissed it under the filed-rate doctrine. See Bryan, 
    377 F.3d at 430
    . Relying on the
    Supreme Court’s 1983 decision in Franchise Tax Board v. Construction Laborers Vacation
    Trust, we first explained that federal question jurisdiction will exist for a state law claim
    only where the plaintiff’s complaint establishes that his right to relief “necessarily depends
    on resolution of a substantial question of federal law.” 
    Id. at 429
     (quoting 
    463 U.S. 1
    , 28
    18
    (1983)). Recognizing that filed tariffs carry the force of federal law, we then resolved that
    any claim seeking to alter the terms of the relationship between parties to a federally
    approved tariff necessarily presents a federal question. By the same token, we recognized
    that a claim for relief that would require a court to determine a reasonable tariffed rate
    specific to a plaintiff “effectively challenges” the terms of the tariff, again posing a
    substantial federal question. Id. at 430-31. That is so, we explained, because the filed-rate
    doctrine bars a court from awarding damages that would have the effect of altering the
    tariffed rate ordinarily paid by the plaintiff. And doing so would disturb the doctrine’s dual
    aims of preventing discrimination among ratepayers and safeguarding the ratemaking
    authority of federal agencies.
    Ultimately, we determined in our Bryan decision that, although the unfair trade
    practices claim underlying the appeal did not directly challenge BellSouth’s tariffed rate,
    it had the legal effect of requesting a court to fix a reasonable rate particular to the plaintiff,
    thereby presenting a substantial federal question.           Because that claim alleged that
    BellSouth’s rate was deceptive and sought damages in that regard, we found that “the only
    plausible reading” of the claim was that plaintiff Bryan effectively sought a refund of some
    portion of BellSouth’s tariffed fee. See Bryan, 
    377 F.3d at 432
    . As a result, awarding the
    requested damages would have violated the filed-rate doctrine. We therefore concluded
    that the district court possessed federal question jurisdiction over the North Carolina unfair
    trade practices claim and should have dismissed it.
    19
    2.
    a.
    Old Dominion’s putative state law claims are of course facially different from the
    North Carolina claim at issue in Bryan, principally alleging the existence of an outside
    contract instead of unfair trade practices. That distinction aside, however, the utility’s four
    claims in its Amended Complaint fit squarely within the map of our analysis in Bryan. In
    fact, although Old Dominion’s claims present an “effective challenge” to the PJM Tariff,
    the claims pursued by Old Dominion set up an even more direct challenge to that tariff than
    was the situation in Bryan. 7
    The Bryan decision controls in this appeal because, as was the situation therein, the
    type of relief sought here is incontrovertibly barred by the governing regulatory tariff. 8
    That is, determining that the four putative state claims afford Old Dominion a right to relief
    in the first instance requires consideration and construction of the federal tariff that controls
    7
    Old Dominion misreads the Bryan decision in part, observing that the amended
    complaint in that case “directly challenged a component of a FCC-filed tariff” and asserting
    that Bryan is inapposite for that reason. See Br. of Appellant 28, 30. But the claims
    presenting direct challenges to BellSouth’s service fee — that BellSouth unjustly enriched
    itself and breached the covenant of good faith and fair dealing by charging an excessive
    fee — were not on appeal in Bryan. See 
    377 F.3d at
    427 & n.4. Rather, plaintiff Bryan’s
    unfair trade practices claim, which only “effectively challenge[d]” BellSouth’s FCC tariff,
    was the claim we assessed in Bryan and is that which is relevant to this appeal. 
    Id. at 430
    .
    8
    We also observe that Bryan’s consideration of a telecommunications tariff
    approved by the FCC does not render that case distinguishable from this litigation, which
    involves a FERC-approved tariff. Public utility regulation, which extends to firms
    supplying electricity, gas, and the like, is “essentially the same form of regulation” as that
    relating to common carriers providing transportation or communications services. See
    Cahnmann v. Sprint Corp., 
    133 F.3d 484
    , 487 (7th Cir. 1998).
    20
    the entirety of Old Dominion’s relationship with PJM. In Bryan, the refund sought by the
    plaintiff was barred and forbidden by BellSouth’s FCC tariff. Here, the reimbursement for
    electricity generation costs sought by Old Dominion’s Amended Complaint is similarly
    precluded by the PJM tariff. In both situations, the plaintiff seeks a special tariffed rate
    unique to it, which federal law plainly disallows. Because no court can award the damages
    that Old Dominion seeks without finding some way around the terms of the PJM Tariff,
    “the plaintiff’s right to relief necessarily depends on resolution of a substantial question of
    federal law.” See Bryan, 
    377 F.3d at 430
     (quoting Franchise Tax Bd., 
    463 U.S. at 28
    ). 9
    More specifically, a straightforward assessment of Old Dominion’s various claims
    reveals that they seek to “alter the terms of the relationship” set forth in the federally filed
    PJM Tariff. See Bryan, 
    377 F.3d at 429
    . As we explained in Bryan, such an objective
    necessarily presents a federal question. Under both the Tariff and Operating Agreement,
    9
    Old Dominion also claims on appeal that the district court ran afoul of the well-
    pleaded complaint rule by considering matters outside of the Amended Complaint —
    including the PJM Tariff, the Operating Agreement, and the FERC and D.C. Circuit
    proceedings — in its jurisdictional analysis. As the court explained in its Dismissal
    Opinion, however, it properly took notice of those matters in scrutinizing the nature of Old
    Dominion’s removed claims. See Dismissal Opinion 2-3 nn. 3-4, 11 n.9 (explaining that a
    court is not confined to pleadings in ruling on a motion to remand). It is not the case that
    “the grounds for removal must appear on the face of the complaint, unaided by reference
    to other pleadings or the notice of removal.” See 14C Charles A. Wright et al., Federal
    Practice & Procedure § 3734 (rev. 4th ed. 2021). Rather, “in the context of possible
    federal-question jurisdiction,” it is appropriate for the court to conduct an examination of
    the record as a whole “to reveal the true nature of the plaintiff’s claim.” See id.; accord
    Franchise Tax Bd. v. Constr. Laborers Vacation Tr., 
    463 U.S. 1
    , 22 (1983) (“[I]t is an
    independent corollary of the well-pleaded complaint rule that a plaintiff may not defeat
    removal by omitting to plead necessary federal questions in a complaint.”). The Dismissal
    Opinion astutely observed that both parties made repeated references to and relied on the
    PJM Tariff and the earlier administrative proceedings and appeals.
    21
    Old Dominion’s relationship with PJM is structured such that when the utility sells its
    power generation capacity to PJM, it may not charge more than $1000 per megawatt-hour.
    The parties do not dispute here — nor did they in the proceedings before FERC and the
    D.C. Circuit — that the losses incurred from Old Dominion’s generating electricity at a
    cost of roughly $1200 per megawatt-hour are not compensable under the PJM Tariff. In
    petitioning FERC for a waiver of the Tariff, Old Dominion alleged that it sustained
    $14,925,669.58 in losses — precisely the sum demanded in each of its four state law claims
    against PJM. There can be no good faith contention that the relief that Old Dominion now
    seeks is different in character than it was during the utility’s administrative proceedings.
    The damages sought are for the costs incurred during the 2014 polar vortex — that is, costs
    “in connection with the transmission or sale of electric energy subject to the jurisdiction of
    [FERC].” See 16 U.S.C. § 824d(a). And as the district court observed, “the governing
    federal statute leaves scant room for [Old Dominion] to maneuver.” See Dismissal Opinion
    19. Simply put, federal law provides that Old Dominion cannot have what it asks for, and
    the utility is not entitled to “artfully plead” away the fact that its claims seek to alter the
    terms of its tariffed relationship with PJM, thereby presenting a federal question under
    Bryan.
    By extension, awarding the relief that Old Dominion now seeks would require
    “entering a judgment that would serve to alter the rate paid by [the] plaintiff,” as the
    damages demanded exceed the sum authorized by law under the PJM Tariff’s rate cap. See
    Bryan, 
    377 F.3d at 429
     (quoting Hill v. BellSouth Telecomms., Inc., 
    364 F.3d 1308
    , 1316
    (11th Cir. 2004)). That is, Old Dominion requests a court to stand in the shoes of 
    FERC 22
    and set a reasonable tariffed rate specifically for purposes of compensating it for its polar
    vortex-related losses. We made plain in our Bryan decision that such a maneuver promotes
    discrimination among ratepayers and impinges upon the ratemaking jurisdiction of federal
    agencies, in contravention of the filed-rate doctrine’s simple mandate that “the rate of the
    carrier duly filed is the only lawful charge.” 
    Id.
     (quoting Louisville & Nashville R.R. v.
    Maxwell, 
    237 U.S. 94
    , 97 (1915)). Bryan explained that any claim “hav[ing] the effect of
    imposing different rates upon different customers” invokes the filed-rate doctrine, poses a
    substantial question of federal law under that doctrine, and must be dismissed pursuant
    thereto. Id. at 430. Again, Bryan compels our conclusion that the district court possessed
    federal question jurisdiction and properly dismissed Old Dominion’s putative state law
    claims as posing an “effective challenge” to the PJM Tariff. 10
    b.
    Under Bryan, it is evident that the substance of each of Old Dominion’s four claims
    necessarily invokes a substantial federal question. 11 The PJM Tariff, then, cannot be
    10
    We expressed in Bryan that our rulings should not be taken to imply that the filed-
    rate doctrine is “conterminous with the scope of federal question jurisdiction.” See 
    377 F.3d at
    430 n.8. Rather, we clarified that in certain instances — as in this appeal — “the
    inquiries merge,” 
    id.,
     and as the district court characterized it here, “there is no daylight
    between the question of jurisdiction and dismissal in regard to claims that challenge federal
    tariffs,” see Dismissal Opinion 28. Indeed, as the Bryan dissenter conceded, “claims
    requiring the court to second-guess the reasonableness of [an agency’s rate] determination
    are properly said to require the court to resolve a substantial federal question.” See 
    377 F.3d at 435
     (Luttig, J., dissenting).
    11
    Old Dominion correctly reminds us that the question of whether a state claim
    “necessarily” poses a federal question typically calls for consideration of whether the
    federal issue constitutes a “necessary element” of the claim. See Pinney v. Nokia, Inc., 402
    (Continued)
    23
    construed simply as a defense to the claims’ allegations when the Tariff is vital to the relief
    that they seek. Old Dominion maintains that, if anything, the Tariff only extinguishes its
    right to relief. We find that characterization to be premature, however, as determining that
    the utility enjoys such a right in the first place requires consulting the terms of the Tariff.
    Old Dominion roots its effort to cast the PJM Tariff as a preemptive affirmative
    defense in our decision in Burrell v. Bayer Corp., 
    918 F.3d 372
     (4th Cir. 2019). Those
    comparative efforts, however, are unavailing. The Burrell decision did not concern any
    dispute over a regulatory tariff, nor did it involve Bryan’s controlling principle that an
    effective challenge to a filed tariff poses a substantial federal question. Burrell involved a
    removal to federal court of state law negligence and product liability claims relating to a
    defective birth-control device. The district court ruled that it possessed federal question
    jurisdiction because the plaintiffs’ complaint was “replete with” explicit allegations that
    the defendant had violated Food and Drug Administration (“FDA”) regulations, thus
    “necessarily raising” substantial questions of federal law. 
    Id. at 379
    . Having concluded
    F.3d 430, 449 (4th Cir. 2005). The parties disputed before the district court whether
    Virginia or North Carolina law governs Old Dominion’s claims. Technical construction
    of the elements of those claims is unnecessary, however, because Bryan directs that the
    nature of the claims and the damages they seek inherently poses a federal question.
    Nevertheless, it is apparent that weighing the merits of Old Dominion’s tort and contract
    claims — under either Virginia or North Carolina law — would require resort to federal
    law. Put succinctly, the allegations set forth in each claim relate solely to the relationship
    between the parties that is exclusively controlled by the PJM Tariff. See Cahnmann, 
    133 F.3d at 488
     (“Any rights that the plaintiff has to complain about a breach of contract are
    rights granted to her by the original tariff . . . .”).
    24
    that it retained jurisdiction over the plaintiffs’ claims, the court granted the defendant’s
    motion to dismiss on preemption grounds.
    We explained on appeal, however, that the statutory provision granting the FDA
    regulatory authority over the birth-control device contained a preemption provision barring
    state remedies for violations of common-law duties unless the alleged wrongs “parallel[ed]
    federal regulatory requirements.” See Burrell, 918 F.3d at 377 (internal quotation marks
    omitted). Accordingly, the plaintiffs were obliged to plead the regulatory violations in
    order to fend off a preemption defense.          We thus concluded that the only “federal
    questions” involved in Burrell operated as defenses to the plaintiffs’ claims and that,
    because jurisdiction does not lie under 
    28 U.S.C. § 1331
     simply because a federal defense
    is “anticipated in the plaintiff’s complaint,” the district court erred in failing to remand. 
    Id. at 381
    .
    Although Burrell’s resolution turned on an application of the substantial federal
    question doctrine, that decision bears little factual resemblance to the dispute now before
    us. The Burrell plaintiffs’ right to the relief they sought could be established without any
    resort to federal law; it was only the case that, after such right was established, federal law
    posed the possibility of cutting off the plaintiffs’ ability to recover. That is not the situation
    here. In this case, there is not merely a “lurking question of federal law in the form of the
    affirmative defense of preemption.” See Burrell, 918 F.3d at 382 (internal quotation marks
    omitted). Instead, the federal law embodied in the PJM Tariff is part and parcel of each of
    Old Dominion’s claims. The utility simply cannot prove that PJM owes it nearly $15
    million “in connection with the transmission or sale of electric energy,” see 16 U.S.C.
    25
    § 824d(a), without “seek[ing] to alter the terms of the relationship . . . set forth in [PJM’s]
    filed tariff,” see Bryan, 
    377 F.3d at 429
    . In sum, Old Dominion’s contention that the Tariff
    is merely a defense to its claims is without merit.
    c.
    In these circumstances, we are persuaded that the Bryan decision permits only one
    resolution of this appeal. The nature of Old Dominion’s claims places them squarely within
    the scope of the PJM Tariff, such that the utility’s right to relief is inextricably intertwined
    with federal law. Critically, that fact does not change by virtue of Old Dominion having
    artfully clothed its inherently federal claims “in state garb.” See Travelers Indem. Co. v.
    Sarkisian, 
    794 F.2d 754
    , 758 (2d Cir. 1986). Just as in Bryan, Old Dominion seeks with
    its putative state claims to alter the terms of its tariffed relationship with PJM, to be
    awarded a tariffed rate different from that enforced against other electric utilities, and
    ultimately to undermine FERC’s statutory authority to ensure that all “rates and charges
    made . . . in connection with the transmission or sale of electric energy” be “just and
    reasonable.” See 16 U.S.C. § 824d(a). Accordingly, each of Old Dominion’s claims by
    necessity poses a substantial federal question, and the district court possessed subject
    matter jurisdiction.
    B.
    1.
    Old Dominion alternatively asserts that, irrespective of how it may bear on this
    appeal, the Bryan decision “has not withstood the test of time.” See Br. of Appellant 28.
    According to Old Dominion, Bryan lacks “continuing precedential force” in view of this
    26
    Court’s subsequent decisions and the Supreme Court’s formulation of the Gunn-Grable
    standard. See Reply Br. of Appellant 29. With respect to our precedent, Old Dominion
    specifically maintains that we have weakened or eliminated Bryan’s “effective challenge”
    standard in explaining federal preemption defenses in Burrell and Pinney v. Nokia, Inc.,
    
    402 F.3d 430
     (4th Cir. 2005), a predecessor to Burrell that similarly found that federal
    regulatory defenses to state law tort claims did not provide a district court federal question
    jurisdiction.
    Old Dominion’s arguments in this regard are unconvincing, as Burrell and Pinney
    are not inconsistent with Bryan. Those decisions bore no relation to Bryan’s assessment
    of veiled challenges to regulatory tariffs and did not question or undermine Bryan’s
    interpretation of the substantial federal question doctrine. Moreover, the PJM Tariff does
    not operate as a defense of the sort considered in Burrell and Pinney. And multiple
    decisions of our sister circuits are in accord with Bryan’s determination that challenges to
    federal tariffs present questions of federal law. See, e.g., Cahnmann v. Sprint Corp., 
    133 F.3d 484
    , 488-89 (7th Cir. 1998); Ne. Rural Elec. Membership Corp. v. Wabash Power
    Ass’n, Inc., 
    707 F.3d 883
    , 891-92, 893 n.5 (7th Cir. 2013); Hill v. BellSouth Telecomms.,
    Inc., 
    364 F.3d 1308
    , 1315-17 (11th Cir. 2004); Marcus v. AT&T Corp., 
    138 F.3d 46
    , 56
    (2d Cir. 1998).
    Moving beyond Burrell and Pinney, Old Dominion argues that the Supreme Court’s
    decisions in Gunn v. Minton, 
    568 U.S. 251
     (2013), and Grable & Sons Metal Products,
    Inc. v. Darue Engineering & Manufacturing, 
    545 U.S. 308
     (2005), impliedly overruled
    Bryan by seeking to “refine” the “unruly” substantial federal question doctrine as it existed
    27
    at the time of Bryan’s decision. See Reply Br. of Appellant 29 (quoting Flying Pigs, LLC
    v. RRAJ Franchising, LLC, 
    757 F.3d 177
    , 182 (4th Cir. 2014)). We agree with the district
    court, however, that Bryan’s explicit standard “closely tracks the Gunn-Grable
    framework,” and that the latter did no harm to the former. See Dismissal Opinion 15 n.11.
    Gunn-Grable principally inquires whether a “state-law claim necessarily raise[s] a
    stated federal issue, actually disputed and substantial,” reflecting the well-established
    standard of the substantial federal question doctrine. See Gunn, 
    568 U.S. at 258
     (quoting
    Grable, 
    545 U.S. at 314
    ). Bryan’s own characterization of that doctrine was drawn from
    the Supreme Court’s decision in Franchise Tax Board v. Construction Laborers Vacation
    Trust, 
    463 U.S. 1
     (1983), which itself informed the Court’s development of the Gunn-
    Grable test. See Grable, 
    545 U.S. at
    312-14 (citing Franchise Tax Board in tracing the
    history of the “longstanding . . . variety of federal ‘arising under’ jurisdiction [that] will lie
    over state-law claims that implicate significant federal issues”).           Gunn-Grable then
    counsels a further normative consideration, namely whether the state claim at hand is
    “capable of resolution in federal court without disrupting the federal-state balance
    approved by Congress.” See Gunn, 
    568 U.S. at 258
    . That concern is also revealed in
    Bryan, however, as reflected in the rationale behind its “effective challenge” standard —
    that is, any lawsuit seeking to enforce or invalidate a federally filed tariff may appropriately
    be heard in the federal courts. In sum, Bryan and Gunn-Grable share a common foundation
    and spell out harmonious legal principles. As such, Bryan remains good law in our circuit.

    2.
    Although the district court grounded its jurisdictional determination in Bryan’s
    standard, it appropriately conducted an independent assessment of the Gunn-Grable
    framework. And we perceive no error in the court’s explicit conclusion that the same result
    obtains when the Supreme Court’s standard is applied to the facts here. The Gunn-Grable
    test provides that there is federal question jurisdiction over a state law claim where the
    claim presents a federal issue that is (1) necessarily raised, (2) actually disputed,
    (3) substantial, and (4) capable of resolution in federal court “without disrupting
    Congress’s intended division of labor between state and federal courts.” See Gunn, 
    568 U.S. at 258
    . Each of those four factors is readily established in this appeal.
    As explained at length above, Old Dominion’s putative state claims “necessarily
    raise” a federal issue by seeking relief made unavailable by a federally filed regulatory
    tariff.    The utility’s Amended Complaint explains that the requested damages of
    $14,925,669.58 reflect costs incurred during Old Dominion’s operations during the polar
    vortex in January 2014. Those costs are not compensable under the PJM Tariff’s rate cap.
    By suing PJM for the expenses anyway, Old Dominion effectively challenges the
    enforceability of PJM’s federal tariff and seeks to amend its terms.
    The federal issue at hand is, of course, also “actually disputed” — the parties
    disagree whether the PJM Tariff precludes Old Dominion’s ability to recover. With regard
    to whether the issue is adequately “substantial,” the Supreme Court in Gunn explained that
    that inquiry looks to “the importance of the issue to the federal system as a whole” and “the
    broader significance of the . . . question for the Federal Government.” See 
    568 U.S. at 260
    .
    29
    Here, Old Dominion seeks to have a state court circumvent FERC’s exclusive authority to
    regulate electric utilities and the interstate electricity transmission market, and we are
    satisfied that a maneuver of that nature poses an issue of “substantial” significance to the
    federal government.
    Lastly, Old Dominion’s claims may appropriately be resolved in federal court for
    much the same reason: they seek to obtain an excuse from strict compliance with federal
    regulatory rules.     Such an endeavor is most appropriately pursued in the federal
    administrative setting, as previously pursued here. PJM’s removal of Old Dominion’s
    claims to federal court did not “disrupt[] Congress’s intended division of labor between
    state and federal courts” in any way — if anything, the removal could best be said to have
    righted that intended division. See Gunn, 
    568 U.S. at 258
    . Accordingly, Gunn-Grable is
    not only compatible with our decision in Bryan, but likewise directs that the district court
    possessed subject matter jurisdiction over Old Dominion’s claims.
    C.
    In sum, Bryan and Gunn-Grable make it clear that Old Dominion’s claims
    necessarily present a substantial question of federal law. In these circumstances, Old
    Dominion’s claims make no bones about seeking relief precluded by the PJM Tariff, asking
    a state court to fix a reasonable tariffed rate applicable only to the utility’s 2014 losses, and
    effectively challenging the terms and enforceability of the Tariff’s rate cap. Given those
    efforts, the district court aptly recognized that the substantial federal question doctrine and
    the filed-rate doctrine work in tandem to render Old Dominion’s claims nonviable. We
    decline Old Dominion’s invitation to turn a blind eye to that reality, and instead resolve
    30
    that the district court was properly vested with federal question jurisdiction and correctly
    dismissed Old Dominion’s claims.
    IV.
    Pursuant to the foregoing, the judgment of the district court denying remand and
    dismissing Old Dominion’s claims with prejudice is affirmed.
    AFFIRMED
