AI Data Centers May Raise US Power Bills by $6.3 Billion

Data Centers Could Add $6.3 Billion to Americans’ Electricity Bills Within 3 Years – Reports

The rapid expansion of AI and cloud data centers is expected to raise electricity costs for millions of Americans. PJM Interconnection, the largest U.S. power grid operator, estimates that its latest capacity auction will add about $6.3 billion in electricity costs to customers over the next three years as demand for power continues to surge.

According to Monitoring Analytics, PJM’s independent market monitor, growing electricity demand from data centers is the main driver behind the higher costs. In the latest auction, capacity prices reached the maximum allowed level of $325 per megawatt-day, reflecting increasing pressure on the regional power system.

The impact has been building for several years. Since 2024, electricity demand from data centers has added an estimated $29.4 billion in capacity costs across PJM’s service area, which covers 13 states and Washington, D.C. Data centers accounted for about 38% of the costs in the most recent capacity auction, according to the market monitor.

The latest auction also highlighted growing supply challenges. PJM failed to secure enough generation capacity to meet its reliability target, leaving the grid about 6.8 GW short of its requirement. The shortfall increases concerns about maintaining reliable electricity supplies during periods of peak demand.

To address rising demand, PJM plans additional measures, including a special reliability procurement process and a registry to track electricity use by large customers such as AI data centers. The grid operator says these steps are intended to strengthen reliability as electricity demand continues to accelerate.

The rapid growth of AI infrastructure is creating challenges beyond the technology sector. Every AI query requires electricity from energy-intensive data centers. Unless new power plants, transmission lines, and grid upgrades are developed quickly, households and businesses could face higher electricity bills as utilities invest to keep pace with demand.

The findings show that the AI boom is reshaping the U.S. electricity market. Policymakers, utilities, and technology companies are now working to expand power generation while protecting consumers from rising costs. Future investment in new generation, grid infrastructure, and energy storage will be critical to supporting AI growth without placing excessive financial pressure on electricity customers.
