Electricity demand across the PJM Interconnection region is growing at an unprecedented pace, driven by rapid expansion of data centers, advanced manufacturing, electrification, and broader economic growth. A new analysis by Å·ÃÀÇéɫƬ finds that without timely deployment of significant new clean energy resources, Mid-Atlantic and Midwest states face serious reliability risks and dramatically higher electricity costs over the next decade.Ìý

There is a growing mismatch between demand growth and new conventional generation that presents an immediate challenge to grid reliability and affordability across the PJM region. To evaluate system-wide impacts, Å·ÃÀÇéɫƬ modeled PJM under two scenarios: aÌýbase case, where all generation resources are available, and a no clean power case, where noÌýnewÌýwind, solar, or storage projects are added beyond those already under construction or required by law.Ìý

Key Data Points:ÌýÌý

• Without new clean energy development, Å·ÃÀÇéɫƬ estimates that ratepayers across nine PJM states would pay anÌýadditionalÌý$360 billionÌýover the next ten years, driven primarily by higher wholesale electricity prices.ÌýÌý
• The average residential household would seeÌý$3,000 to $8,500ÌýinÌýadditionalÌýelectricity costs over theÌýnextÌýdecade.ÌýÌýÌý
• In the “no new clean power” case, PJM becomes increasingly reliant on aging, higher-cost fossil fuel generation and imported electricity. Net power imports rise nearly 300% by 2035, increasing exposure to fuel price volatility and operating hours with extremely high electricity prices.Ìý
