PJM Interconnection announced the results of its latest capacity auction. For the majority of the PJM region, capacity prices for the 2025/26 delivery year hit record highs, to $269.92/MW-day, up from $28.92/MW-day in the last auction. This will impact ComEd electricity bills in June of 2025. Capacity prices are a portion of ComEd’s supply rate–it is not immediately clear how much this will increase overall bills.

It’s been a busy summer advocating for electric customers at PJM, a power grid operator that controls the flow of electricity over big transmission lines that stretch across northern Illinois and all or parts of a dozen other states. Here’s a breakdown of some major developments concerning PJM this summer–the good, the bad, and the ugly.

"The complaints build on a long-simmering dispute among the market monitor, consumer advocates and the clean energy industry over whether efficiency programs should be treated like traditional generating resources."

"In a strong step forward for affordable, reliable and clean energy, a committee at the nation’s largest power grid operator voted overwhelmingly to begin a discussion on how to design and evaluate cost-effective alternatives to running expensive, polluting power plants past their desired close date."

“PJM is dragging its feet on the clean energy transition and doing everything it can, instead, to create exceptions for itself,” said Clara Summers, the Consumers for a Better Grid campaign manager at the Citizens Utility Board.
