Power prices on America's largest grid rose 76%
Power prices on the PJM Interconnection, the largest electrical grid in the U.S., have surged by 76% over the past year. This increase is primarily attributed to the rising demand from data centers, which has outpaced the grid's capacity to supply electricity. Monitoring Analytics has criticized PJM for its inadequate response to this demand and for delaying necessary upgrades.
- ▪Wholesale prices for one megawatt-hour of electricity rose to $136.53, up from $77.78 last year.
- ▪Monitoring Analytics stated that the current supply of capacity in PJM is not adequate to meet the demand from large data center loads.
- ▪PJM has faced criticism for its lack of transparency and for delaying software upgrades that are essential for managing the grid.

Monitoring Analytics pointed the finger at data centers and PJM’s failure to handle their surging demand adequately. The market monitor pulled no punches. “The price impacts on customers have been very large and are not reversible,” Monitoring Analytics wrote.
