PJM Launches Major Capacity Market Reform Review as Grid Reliability Concerns Grow

PJM Interconnection on May 6 launched a broad review of its wholesale electricity markets with the release of a report outlining long-term options for maintaining grid reliability amid surging power demand, rising costs, and weakening investor confidence. The paper, titled “Powering Reliability Through Market Design,” assesses whether the existing capacity market can continue to support reliability as large data centers rapidly reshape demand growth across the region.

The grid operator noted that current market conditions are increasing strain on both consumers and developers. Electricity demand tied to artificial intelligence and data center expansion is increasing far faster than new generation resources can be developed and connected to the grid. At the same time, construction costs for new power plants have climbed sharply, development timelines have lengthened, and shifting federal and state policies have increased uncertainty for investors.

PJM’s Board of Managers earlier this year directed staff to evaluate both immediate and structural reforms to the capacity market, known as the Reliability Pricing Model. The review follows mounting concern over price volatility in recent capacity auctions and questions about whether short-term market signals alone can attract enough new generation to preserve reliability.

The report outlines three broad approaches for stakeholder consideration rather than endorsing a single solution. One option would preserve a common reliability standard through expanded long-term commitments designed to shield consumers from price spikes while supporting investment in new resources. A second approach would allow varying reliability standards based on customer class, geography or willingness to pay. A third framework would shift greater emphasis toward energy and ancillary service markets, with the capacity market serving primarily as a backstop mechanism.

The grid operator warned that the current framework may no longer be sustainable and indicated that state regulators, federal policymakers, consumer advocates and market participants will play a central role in shaping the next phase of market design reforms.
