The Federal Energy Regulatory Commission (FERC) issued an order on the Minimum Offer Price Rule (MOPR) in the PJM Interconnection, L.L.C. (PJM) tariff on June 29, addressing recent controversies over the capacity market impact of some generators receiving state rate subsidies. In the June 29 order, FERC rejected two alternative proposals by PJM to modify the MOPR in response to concerns of state subsidization of new generation resources, granted a complaint filed by market participants against the MOPR, and instituted a paper hearing proceeding under Section 206 of the Federal Power Act (FPA) to determine the just and reasonable revisions to the PJM tariff that would be necessary to address the subsidization issues. The resulting FERC proceeding promises to significantly reshape the PJM capacity market, which has struggled for years to address in a manner that FERC would accept the market impacts of subsidies to specific resources. FERC’s decision, although limited to PJM, could also lead to widespread changes in other capacity markets dealing with the same issues.
The MOPR is a feature of PJM’s Reliability Pricing Model (RPM), which is PJM’s capacity market. Through the RPM, PJM conducts a series of auctions to procure resources to meet regional reliability reserve requirements. A variety of resources may participate, including fossil-fuel, renewable, and demand response resources. Winners of the auction are awarded a fixed price for their capacity in exchange for a commitment to make their capacity available for dispatch by PJM.
