PJM finds generation capacity shortfall, points to new data centers
July 19, 2026
The largest grid in the U.S. continues to find electricity demand rising faster than new generation is being built. On Tuesday the PJM Interconnection, the body in charge of the grid from New Jersey to Virginia and west to Chicago, announced results from its capacity auction for the 2028 delivery year. For the third year in a row, capacity prices hit the administrative price cap at $325/MW-day. Without the cap, PJM estimates prices would have cleared at $554/MW-day. The price cap protects households and businesses from paying billions to existing generators when construction and interconnection timelines limit how fast new supply can come online. It also protects consumers from potentially overstated data center load forecasts. However, the cap reduces the incentive to build new power plants, batteries, or demand response in a region where capacity is urgently needed. Source: PJM.
