Electricity costs are set to climb across a broad swath of the eastern United States, driven largely by the surging energy demands of data centers. The price signal came this week from PJM Interconnection, the grid operator covering 13 states, which released results from its latest auction for power delivery from June 2028 through May 2029. The auction showed a sharp increase in capacity costs, a trend that analysts attribute directly to the rapid buildout of facilities supporting artificial intelligence, cloud computing, and other data-intensive work.

The independent market monitor, Monitoring Analytics, has flagged the shift, noting that data centers alone are expected to add billions of dollars in new electricity expenses over the next several years. These facilities, which require massive, round-the-clock power for servers and cooling systems, are now the single largest driver of new demand in the PJM region. Utilities and grid planners are scrambling to secure enough generation capacity to meet this load, which has pushed auction prices well above previous cycles.

For businesses and households in the affected states, the immediate impact will be higher bills as these capacity costs are passed through. But the longer-term story is about infrastructure. The auction results underscore a fundamental change in how electricity is consumed, with digital infrastructure now competing directly with traditional industrial and residential users for supply. PJM’s next steps will be closely watched, as the region tries to balance reliability, affordability, and the economic pull of the data center boom.
