Opinion concurring in the judgment filed by Senior Circuit Judge EDWARDS.

KAREN LECRAFT HENDERSON, Circuit Judge: PJM Interconnection LLC (PJM), which manages an electrical grid spanning thirteen states and the District of Columbia, hired Petitioner Market Monitoring Analytics LLP as its independent market monitor (IMM) to monitor and report on market conditions in PJM’s region. For a time, PJM permitted IMM to sit in on meetings held between the PJM Board of Managers (Board) and PJM’s Liaison Committee, a nonvoting body that serves as a forum for open communications between PJM Members and the Board. That practice came to an end, however, when PJM decided to enforce a provision in the Liaison Committee’s charter limiting attendance to end-use customers and regulated utilities serving the PJM market region. IMM complained to the Federal Energy Regulatory Commission (FERC or Commission) regarding this policy change and the Commission sided with PJM. IMM now petitions for review. Because we conclude that IMM lacks standing, we dismiss the petition for lack of jurisdiction.

I. BACKGROUND

Since the 1990s, the Commission “has encouraged transmission providers to establish ‘Regional Transmission Organizations’” (RTOs) as part of a broader effort to create a 3 more competitive and efficient electricity market. Morgan Stanley Cap. Grp. Inc. v. Pub. Util. Dist. No. 1 of Snohomish Cnty., 554 U.S. 527, 536 (2008). RTOs are Commission- regulated entities that have operational control of “all transmission services in a particular region independent of the utilities that own the transmission lines.” NRG Power Mktg., LLC v. FERC, 718 F.3d 947, 950 (D.C. Cir. 2013). “Among other things, these organizations manage the electricity grid in their respective geographic regions, steady the supply of and demand for energy in those regions, and ensure that the grid remains reliable over the long haul.” Vistra Corp. v. FERC, 80 F.4th 302, 307 (D.C. Cir. 2023) (citation omitted).

The Commission’s rules also require each RTO to “perform a market monitoring function to ensure that markets within [its] region . . . do not result in wholesale transactions or operations that are unduly discriminatory or preferential.” Elec. Power Supply Ass’n v. FERC, 391 F.3d 1255, 1260 (D.C. Cir. 2004) (citation modified); accord 18 C.F.R. § 35.34(k)(6). RTOs “can choose to perform the monitoring function themselves or use an independent contractor.” Elec. Power Supply Ass’n, 391 F.3d at 1260.

Whether they are in-house or hired from the outside, the Market Monitors operate as auditors within their RTOs, “largely confined to observing the [RTO] market’s operations and . . . offering recommendations” on how to improve market conditions. Old Dominion Elec. Coop. v. FERC, 892 F.3d 1223, 1233 (D.C. Cir. 2018). They generally have no authority to implement Commission-approved tariffs and must operate independently of any regulated utilities operating within the RTO’s market region. See 18 C.F.R. § 35.28(g)(3)(iii)(A), (vi). Under the Commission’s rules, the Market Monitor performs three core functions: (1) “[e]valuate existing and proposed market rules, tariff provisions and market design elements and 4 recommend proposed rule and tariff changes”; (2) “[r]eview and report on the performance of the wholesale markets” to its RTO; and (3) “[i]dentify and notify the Commission” of any violations of the Commission’s rules or the RTO’s tariffs. 18 C.F.R. § 35.28(g)(3)(ii)(A)–(C). “[T]o enable the Market Monitoring Unit to carry out its functions,” the Commission’s rules require each RTO to provide its Market Monitor with unfettered “access” to the RTO’s “market data” and “databases of market information.” Id. § 35.28(g)(3)(i)(A)–(B). RTOs must also codify these disclosure policies in their tariffs. See id. § 35.28(g)(3)(i).

PJM is an RTO that operates transmission facilities in thirteen states and the District of Columbia. Del. Div. of the Pub. Advoc. v. FERC, 3 F.4th 461, 463 (D.C. Cir. 2021). As the Commission’s rules require, PJM outlined the powers and responsibilities of its Market Monitoring Unit in Attachment M of its Open Access Transmission Tariff (Attachment M or PJM Tariff).

Section IV of Attachment M describes the functions and responsibilities of PJM’s Market Monitor. It provides that the Market Monitor is to “objectively monitor the competitiveness of PJM Markets, investigate violations of FERC or PJM Market Rules, recommend changes to PJM Market Rules [and] prepare reports for the Authorized Government Agencies.” Addendum (Add.) 14–15, § IV.A. The Market Monitor may also “initiate and propose” changes to the PJM Market Rules and the PJM Tariff. Add. 15–16, § IV.D. Subsection G of Section IV provides that the Market Monitor “may, as it deems appropriate or necessary[,] . . . participate . . . in stakeholder working groups, committees or other PJM stakeholder processes.” Add. 17. 5 Attachment M goes on to address, in Section V, the Market Monitor’s entitlement to “Information and Data.” Add. 21 (emphasis omitted). Pursuant to Section V, the Monitor “shall be provided” all “information gathered or generated by PJM in connection with its scheduling and dispatch functions, its operation of the transmission grid in the PJM Region or its determination of Locational Marginal Prices.” Add. 21, § V.A. Section V also empowers the Market Monitor to make reasonable requests for information in the hands of any PJM Market Participant, so long as the Monitor “determines that [this] information is required to accomplish” its objectives. Add. 21, § V.B.1. And if an entity “does not provide [the] requested information within a reasonable time, the Market Monitoring Unit may initiate . . . regulatory or judicial proceedings to compel . . . production,” by, for example, “petitioning the Commission for an order.” Add. 21–22, § V.B.2.
