AI Data Centers Fuel Billions in New Power Costs as Regulators Scramble to Contain the Surge
AI’s explosive growth is colliding with the U.S. power grid, and the fallout is about to hit household and business electricity bills across 13 states served by PJM Interconnection. Consumers are being asked to underwrite a massive new layer of demand from data centers just as political and regulatory pushback mounts.

In 2024, soaring prices inside PJM’s territory triggered a lawsuit from Pennsylvania Governor Josh Shapiro over “skyrocketing” power costs, a case that resulted in a settlement and new price caps on what generators can charge for keeping power ready at times of peak demand. Those caps would soon become the only brake on an AI-driven cost surge.

By mid-2024 through 2026, data centers rapidly expanded across PJM’s footprint, especially in Virginia, the country’s largest data center hub. Their electricity needs piled an estimated $29 billion onto consumer bills in the region beginning in 2024, setting the stage for more dramatic hikes to come.

In PJM’s latest capacity auction, published this week, that pressure became unmistakable. The price generators charge PJM for power readiness hit the system’s cap of $325 per megawatt-day, translating into $16.4 billion in costs for ratepayers. PJM’s independent market monitor estimates that data centers alone account for roughly $6.3 billion of that total, the portion now directly tied to AI-related demand.

Absent the cap secured in the Pennsylvania settlement, PJM says the clearing price would have reached $554.72 per megawatt-day — implying far steeper increases. Even with caps, the largest U.S. grid operator now concedes that it will add $6.3 billion in electricity costs for consumers over the next two years because of the booming energy needs of data centers, hitting millions of households and businesses across its 13-state region.

Political resistance is intensifying. This week, New York Governor Kathy Hochul imposed the nation’s first statewide moratorium on large-scale data center construction, explicitly citing fears over “spiraling utility rates” tied to AI and cloud buildouts. As regulators weigh grid reliability, climate goals, local pollution, and noise against the economic upside of the AI boom, investors are watching to see whether mounting community and policy backlash begins to cool what has so far been a highly lucrative data center spending spree.
