What's driving the surge in data center electricity demand?
U.S. data center electricity use is projected to nearly double — from 4% to 9% of total national consumption — by 2030. That forecast comes from ANS Nuclear Newswire. The shift is already affecting utility planning and grid interconnection queues across the country.
Artificial intelligence is a key driver of this growth. Broader digital infrastructure expansion is pushing demand higher as well.
Why does nuclear fit what data centers need?
Large hyperscale data center campuses can require hundreds of megawatts of power. They also need maximum uptime — around the clock, every day of the year.

Nuclear plants deliver reliable, 24/7 electricity with stable long-term costs. That directly matches what data center operators require, and it reduces exposure to fuel-price swings and transmission constraints, as reported by ANS Nuclear Newswire.
Leading hyperscalers also carry aggressive decarbonization commitments. Those commitments rule out heavy reliance on fossil fuels, and nuclear generation meets that clean-energy requirement.
The restart of Three Mile Island as the Crane Clean Energy Center is one example of how existing nuclear capacity is being repositioned to serve this kind of demand.
What else do data centers need beyond power?
Power is only part of the picture. Data centers also need fiber connectivity, a skilled local workforce, and community acceptance.
On the other side, they can deliver real tax revenue and jobs — especially when paired with a major energy project. Nuclear plants can meet the core energy requirements while also supporting the broader siting and economic factors that come with large data center deployments.
Federal land is another avenue being explored. The DOE has opened a request for information on AI data centers on federal land, which could expand where these facilities get built.
Frequently asked questions
Q: How much U.S. electricity do data centers use now, and where is that headed? A: Data centers currently account for about 4% of U.S. electricity consumption. That figure is projected to reach 9% by 2030.
Q: Why is nuclear considered a strong match for data centers? A: Nuclear provides 24/7 reliable electricity with stable long-term costs. It reduces exposure to fuel-price volatility and supports decarbonization goals. All of those factors align with what hyperscale data centers need for uptime and clean energy commitments.
