The US Department of Energy has launched an initiative to add 5 gigawatts of nuclear capacity through power uprates at existing plants and restarts of retired reactors, according to federal energy data. The effort aims to expand generation from the current fleet without the longer timelines associated with new construction.

The push fits within a broader capacity goal. Federal policy targets growth in US nuclear capacity from roughly 100 gigawatts today to 400 gigawatts by 2050, a fourfold increase that would require a combination of new reactors, life extensions, uprates, and restarts. Reaching that level would mark one of the largest expansions of any electricity source in the country.

Restarts have become a central tool. The Nuclear Regulatory Commission approved its first-ever reactor restart at Holtec's Palisades plant in Michigan, and additional restarts at Crane Clean Energy Center and Duane Arnold are scheduled for 2027 and 2029. Much of the demand pull comes from technology companies seeking firm, carbon-free power for data centers.

A pipeline of advanced reactors and small modular designs is also developing across the country, adding to the projected capacity growth. The data shows a sector pursuing near-term gains from existing assets while building toward a much larger long-term capacity base, with electricity demand from computing and electrification driving the planning.
