PJM Forecasts Record 166.3-GW Demand as Heatwave and AI Load Strain US Grid

Summary
PJM Interconnection expects electricity demand to hit a record 166.3 gigawatts on Thursday evening, topping its previous summer peak from 2006 as extreme heat spreads across the central and eastern US.
Temperatures above 100F from Boston to Washington and heat indexes up to 114F are set to drive heavy air-conditioning use through the July 4 holiday weekend and World Cup knockout matches in several host cities.
New York's grid operator also sees demand nearing record highs, while MISO said its peak could be challenged across 15 Midwest and Southern states and that it may rely on PJM for support.
PJM warned in May that demand is rising faster than new supply can be built, with power plants taking twice as long and costing twice as much as a decade ago.
AI data centers and electric vehicles are adding to the strain, especially in northern Virginia, as US health officials warn prolonged heat can be deadly after 2,325 heat-related deaths were recorded in 2023.

Data Center-Driven Grid Crisis: PJM’s Struggle with Record Demand, Soaring Prices, and Sustainability Challenges
Overview
As early July 2026 approaches, the PJM Interconnection region faces a critical period of grid strain caused by a combination of an anticipated heatwave and the rapid addition of large data centers in Maryland and nearby states. This surge in energy demand from data centers is making the grid more vulnerable, prompting urgent questions for grid operators and policymakers about how to maintain reliability and fairly distribute costs. In response, PJM’s Board is actively considering new strategies, including requiring data centers to provide their own power, to address these immediate and growing challenges.
