PJM Board Moves Forward with MOPR Overhaul

Jul 9, 2021

Reading Time : 2 min

The MOPR imposes an offer floor (i.e., a minimum bid price) on certain electric generation resources in PJM’s capacity auctions. While historically the rule has applied in only limited circumstances, FERC directed major reforms to the MOPR in 2019 that expanded its reach: The bid price of any generator receiving a “state subsidy” is mitigated to the MOPR’s offer floor under the current rule. The expanded rule has become a major point of tension between FERC and the states, which view the rule as impeding their ability to promote emissions-free electric generation such as wind, solar and nuclear power.

If approved by FERC, the forthcoming reforms would significantly scale back the MOPR and would provide states with more latitude to shape their resource mixes without federal intervention. All market sellers would be required to provide two attestations to PJM prior to an auction to avoid mitigation: (1) an attestation confirming that the seller is not exercising buyer-side market power (BSMP) and (2) an attestation confirming that the seller is not receiving “Conditioned State Support.” The first attestation means that the seller is not offering its resource(s) uneconomically with the intent of suppressing market clearing prices. The second means that the seller is not receiving financial support from a state for the sale of a FERC-jurisdictional product, where such support is conditioned on clearing in a capacity auction. 

If PJM has reason to believe, despite an attestation to the contrary, that a seller is receiving “Conditioned State Support,” PJM will submit a filing with FERC indicating its intent to apply the MOPR and will do so pending FERC approval. In practice, very few state energy policies would fall into this new category, particularly since any such “conditioning” likely would already be preempted under federal law, consistent with the Supreme Court’s Hughes decision.1 With regard to the possible exercise of BSMP, PJM will make its own determination whether a sell offer constitutes an exercise of BSMP, though PJM may elevate any such concern to FERC. PJM may request additional documentation from market participants if PJM suspects the potential for BSMP.2 

A summary of the PJM proposal is available here. The FERC filing is expected later this month.


1 See Hughes v. Talen Energy Mktg., LLC, 577 U.S. 1117 (2016). PJM’s proposal makes clear that state subsidies will not be deemed Conditioned State Support so long as they do not condition such support on clearing in a PJM auction.

2 PJM’s proposal notes that PJM may suspect BSMP if a seller intends to offer a resource that PJM believes is uneconomic in such a way that will lower the clearing price in an area where the seller has a “net short” position (i.e., the seller is buying more capacity than it is selling).

On January 16, 2026, the National Energy Dominance Council (NDEC) and governors from each of the 13 states in PJM issued a Statement of Principles urging PJM Interconnection, L.L.C. (PJM) to hold an emergency backstop auction and take other measures to support the entry of new capacity to preserve the reliability of the PJM region. The Statement of Principles calls on PJM to expeditiously file with the Federal Energy Regulatory Commission (FERC or the Commission) tariff revisions that would overhaul aspects of PJM’s market rules to address rising electricity prices and growing reliability risks in the PJM region. The Statement of Principles comes at a time of growing concern that PJM will not have sufficient capacity in the coming years to meet demand due to the retirement of existing generation resources, the glacial pace of new entry and projected increased demand associated with data center development.

On December 19, 2025, the Federal Energy Regulatory Commission (FERC or the Commission) issued its much-anticipated order on show cause proceeding concerning the co-location of generation and load within the PJM Interconnection, L.L.C. (PJM) market.[1] In the order, the Commission finds that PJM’s tariff is unjust and unreasonable because it does not provide sufficient clarity on the rates, terms, and conditions of service applicable to generators serving Co-Located Load and does not include transmission services appropriate for customers that are willing and able to limit their use of the transmission system in certain conditions.

On November 7, 2025, the New York Department of Environmental Conservation (NYSDEC) and the New Jersey Department of Environmental Protection (NJDEP) reversed their prior positions and approved Clean Water Act (CWA) Section 401 Water Quality Certifications and other environmental permits for the Transcontinental Gas Pipeline Company’s (Transco) Northeast Supply Enhancement Project (NESE). NESE is a 25-mile natural gas pipeline expansion project certificated by the Federal Energy Regulatory Commission (FERC) that is intended to deliver 400,000 dekatherms per day of natural gas produced in Pennsylvania to local distribution company customers in New York City through new facilities in Middlesex County, New Jersey and an underwater segment traversing the Raritan and Lower New York Bays.
