Electricity demand in Pennsylvania and surrounding states is outstripping supply
Electricity demand in Pennsylvania and surrounding states continues to grow, causing high prices and potential grid strain. The regional grid operator, PJM Interconnection, held its capacity auction, securing power for 2028 with prices hitting a cap. The demand is largely driven by the expected growth of data centers, leading to calls for their exclusion from the general auction.
Electricity demand in Pennsylvania and neighboring states is outstripping supply, leading to sustained high prices, according to the recent capacity auction results from PJM Interconnection, the regional grid operator. The auction, which secures electricity for generation starting in 2028, saw prices hit a cap of $325 per megawatt day, a cap initially put in place after Pennsylvania Gov. Josh Shapiro sued PJM over a previous spike in costs. Despite the cap, consumers are facing embedded high prices, with former Pennsylvania Consumer Advocate Patrick Cicero noting that electric rate increases over the last 18 months are costing ratepayers an additional $220 to $320 annually.
PJM President and CEO David Mills stated that demand for electricity continues to grow faster than supply, leading to slimmer reserves and increased risk for the system. Robert Routh of the Natural Resources Defense Council (NRDC) highlighted that this surging demand is primarily driven by the anticipated expansion of data centers. Both NRDC and some lawmakers are advocating for data centers to be excluded from the general capacity auction, arguing that their unique characteristics and significant power consumption disproportionately drive up prices for all other consumers. PJM, for its part, has indicated it is taking steps to prepare for this new demand, including helping large load customers directly purchase power from generators.
