Data centers drive 55% of US electricity demand growth
Data centers are driving a significant increase in U.S. electricity demand, reversing a two-decade trend of flat consumption. Projections from various organizations indicate that data centers could account for a substantial portion of national electricity use by 2030, putting immense strain on the power grid. Utilities are struggling to build new generation capacity quickly enough to meet this rapidly accelerating demand.
After two decades of stagnant growth, total U.S. electricity demand is surging, primarily driven by the rapid expansion of data centers. According to the Lawrence Berkeley National Laboratory, data centers consumed 176 terawatt-hours in 2023, more than double the amount from five years prior. The Electric Power Research Institute (EPRI) projects this could escalate to 9% to 17% of all U.S. electricity by 2030, placing significant pressure on national power infrastructure.
The North American Electric Reliability Corporation (NERC) dramatically revised its decade-long electricity demand forecast in 2024, increasing it by 65% to 132 gigawatts. This surge is creating a critical challenge for utilities, which face a five- to ten-year timeline to permit and build new power plants, a pace far slower than the 18-month construction cycle for data centers. The imbalance leads to perpetual power shortfalls, making electricity more expensive for consumers.
Artificial intelligence applications are further intensifying this demand, with Goldman Sachs Research estimating AI could account for over a quarter of global data center power demand by 2027. States like Virginia, where a quarter of the electricity already serves data centers, and Texas, which sees competition for grid capacity from both AI data centers and cryptocurrency miners, are experiencing significant strain. Projections by EPRI indicate that by 2030, states such as Arizona, Indiana, Iowa, Nebraska, Nevada, Oregon, and Wyoming could also see data centers consume a fifth or more of their electricity, necessitating substantial grid upgrades.
