PJM Interconnection, the operator of the Mid-Atlantic power grid serving Maryland and 12 other states, is moving to finalize regulations governing how data centers connect to and draw power from the regional grid. The rules are expected to address queue management, cost allocation, and load forecasting as data center demand has surged across the region. PJM's service territory includes some of the highest concentrations of data center capacity in the world, particularly in Northern Virginia. The finalized regulations will affect how future projects are planned and approved across the mid-Atlantic and Midwest.
PJM's rule changes will directly shape the pace and economics of data center development across a 13-state footprint that already hosts a disproportionate share of U.S. data center capacity. Formal interconnection rules carry binding force, meaning hyperscalers and colocation providers will need to adjust siting and contracting strategies to comply.
Named grid operator PJM, a formal regulatory finalization process, and the Maryland policy context triggered selection. The story's binding regulatory consequence for a major U.S. power grid region ranked it near the top of this run.
