PJM stakeholders Jan. 22 kicked off discussions on creating a “backstop” auction to be held in September at the insistence of the Trump administration and the governors of the RTO’s 13 states.
The Members Committee discussed the feasibility of holding such an auction and how the logistics of creating the rules for doing so should be balanced with other elements of the Critical Issue Fast Path (CIFP) proposal the Board of Managers selected for addressing large load growth Jan. 16.
The White House’s National Energy Dominance Council (NEDC) and state governors, issued the same day as the board announced its choice, envisions a one-time auction that procures new resources for a 15-year commitment period. (See White House and PJM Governors Call for Backstop Capacity Auction.)
“The PJM board should file tariff revisions expeditiously, as PJM has already received stakeholder input through the 2025 [CIFP] process, and no further CIFP processes are necessary,” they said in a statement of principles.
In its announcement of its CIFP proposal choice, the board said the RTO’s existing backstop capacity procurement method should be accelerated: It is currently triggered only after three consecutive capacity auctions fall short of the reliability requirement. (See PJM Board of Managers Selects CIFP Proposal to Address Large Load Growth.)
“Accelerating a backstop capacity procurement is especially necessary in light of FERC’s recent decision on co-location and its request for more information on utilization of this backstop procurement framework,” it said in a letter to stakeholders.
Addressing the MC on Jan. 22, board Chair and interim CEO David Mills said both the government’s and the board’s proposals don’t bear any resemblance to the existing backstop. PJM’s load forecast shows data center demand is likely to rise for a significant amount of time. “A one-time auction is not going to scratch the itch completely,” he said.
Designing an auction able to provide certainty for the supply and demand side of the auction on that timeline will require the states and FERC to be involved and take ownership over the outcome, Mills said. What can’t be allowed to happen is for there to be extended fruitful discussions only for an uninvolved party to fire a flare in the final hours, he said.
Even with a backstop auction, Mills said there are significant barriers to getting new resources built, including transmission upgrades, financing, tariffs, siting, permitting and supply chain constraints. Significant new capacity is unlikely to be available until 2032.
Manager Vickie VanZandt said the challenges of siting transmission could impede any resource adequacy benefits a backstop auction might provide. States and transmission owners will have to work together to overcome the likelihood of immense public pushback against network upgrades required to make new resources procured through a backstop deliverable.
Pennsylvania Deputy Secretary of Policy Jacob Finkel said he could not underscore the gravity of a bipartisan group of 13 governors and the White House calling on PJM to conduct the auction. He pushed back against suggestions that the September deadline was meant to be before the midterm elections in November, saying nine months seemed to be workable.
“We want this RTO to work; we want to solve this problem, but changes have to occur,” he said.
Constellation Energy Vice President of Wholesale Market Development Adrien Ford said the feasibility of holding a backstop auction in September depends on the design PJM decides to adopt and whether it tries to build off the existing capacity product or define a new one.
She said Constellation has been working with Vistra to revise the backstop mechanism that a coalition of resource owners and data center developers proposed during the CIFP process that would build off the existing definition of capacity, triggering if a capacity auction cleared below 98% of the reliability requirement and allowing for up to seven-year commitments. The auction would be open to new or reactivated resources; existing resources with offers higher than the maximum price for the Base Residual Auction that cleared short; and traditional demand response.

Mills said his vision of success is a ready-to-launch mechanism that accomplishes what PJM has been asked to do: Establish a market mechanism that marries new committed demand to new supply. To get to that point, stakeholders will need to chew through a lot of details, but he said that’s within their capability. He said he believes that in four to six weeks, there will be great progress on creating a workable design.
Unintended Consequences
Mills also called for stakeholders to identify areas where unintended consequences could be created by running auctions to procure capacity outside BRAs. One such challenge could be the creation of an additional cycle of grid upgrades being triggered.
The PJM Public Power Coalition’s Carl Johnson warned that a parallel capacity auction with the potential to deliver higher value for sellers could cannibalize projects already in the interconnection queue. If a substantial number of planned resources that PJM expected to come online and offer into the Reliability Pricing Model instead seek to participate in a backstop auction, there would be no net change in the amount of supply available to the grid, and the market would be even more short.
The Natural Resources Defense Council’s Claire Lang-Ree said the success of the backstop auction relies on the other components of the board’s CIFP proposal. If the bring your own new generation (BYONG) and “Connect and Manage” DR pathways for data centers aren’t strong enough, she said it would be hard to see why they would want to participate in a potentially more expensive backstop auction.
The BYONG model would allow large loads to meet their own capacity needs with new resources, which would qualify for an expedited interconnection track. Large loads that do not participate in BYONG would be subject to curtailment through load-serving entities ahead of pre-emergency load management resources in a model similar to PJM’s proposed mandatory non-capacity backed load (NCBL) brought during CIFP — though the load would remain in the capacity market. (See PJM Revises Non-capacity Backed Load Proposal.)
Mills said those changes are another area that will require buy-in from states to be successful: Because PJM cannot distinguish between consumers directly, it will be up to state utility commissions and utilities to disentangle large loads from organic economic growth.
Greg Poulos, executive director of the Consumer Advocates of the PJM States (CAPS), said he is concerned an auction awarding multiyear commitments would shift risk onto consumers.
Consumer advocates and representatives of Pennsylvania Gov. Josh Shapiro’s office urged PJM to extend the price collar that limited capacity prices to between $175 and $325/MW-day for the 2026/27 and 2027/28 auctions. Finkel said the 2028/29 BRA is not going to be able to procure enough supply and will clear at the $550/MW-day maximum price, a jump in prices he argued would not come with any reliability benefit.

Paul Sotkiewicz, president of E-Cubed Policy Associates, said constraining capacity prices would ensure that a parallel backstop auction would cannibalize resources from RPM.
