As data centers continue expanding across the mid-Atlantic, Audubon-based PJM Interconnection is modernizing how new energy projects connect to the grid, writes Ethan Howland for Utility Drive.
Recent reforms to PJM’s surplus interconnection rules have opened the door for a surge in battery storage development. This aims to address mounting pressure on capacity prices and power reliability.
The changes come as new storage projects, like two 10-megawatt batteries in Virginia, signal a shift toward cleaner, more flexible infrastructure. These projects help offset demand spikes from data centers while reducing reliance on inefficient peaker plants.
Analysts estimate PJM could now unlock up to 26 gigawatts of interconnection capacity for new resources, including batteries, at a time when regional grid stability is under scrutiny.
Despite lagging behind California and Texas in storage deployment, PJM’s reform marks a turning point. The operator’s new fast-track process already includes 7 gigawatts of storage projects that could come online within the next two capacity auction cycles.
With talk of data centers coming to places like Conshohocken, these upgrades represent a critical link between technology growth and sustainable energy planning.
