Data centers drive 76% surge in PJM power prices

Wholesale power prices in the PJM Interconnection, the largest grid market in the nation, soared by almost 76% in the first quarter year-over-year, largely due to the escalating energy demands of data centers. Monitoring Analytics, PJM's independent market monitor, reported that the total cost of wholesale power reached $136.53 per megawatt-hour, up from $77.78 in the same period last year. The monitor warned that these "very large" price impacts on customers are irreversible and will intensify unless the issues related to data center load are promptly addressed. The report highlighted that data center growth, particularly for artificial intelligence, has contributed to a $13 billion cost increase for customers across PJM's sprawling 13-state grid, which includes Virginia, home to the world's largest concentration of data centers. PJM, overseen by the Federal Energy Regulatory Commission (FERC), faces criticism from governors and utility leaders for not responding urgently to the rising prices and a backlog of generation projects. Pennsylvania Gov. Josh Shapiro had threatened to withdraw his state from PJM if actions were not taken, leading to a cap on future capacity prices through 2029. PJM has also recommended solutions, including requiring utilities and suppliers to make longer-term commitments for power supply. PJM spokesperson Jeff Shields stated that the rising prices accurately reflect tightening supply-and-demand conditions in the wholesale markets, and the grid operator is working with states and member companies to mitigate consumer impacts through market rule reforms and transmission expansion projects.
