Data Centers Turn To Nuclear Power
Coverage from Iowa Capital Dispatch, Yahoo Finance, and others
Data center developers and technology companies are turning to existing nuclear plants, proposed small modular reactors, and long-term power contracts as electricity demand rises and grid availability tightens.
Microsoft, Google, Meta, and Riot Platforms are pursuing different versions of this approach, ranging from the planned restart of Iowa’s 615-megawatt Duane Arnold plant to early-stage reactor concepts for future AI campuses. The strategy could provide dependable power, but permitting, financing, construction timelines, supply chains, and local opposition make many nuclear-powered data center plans long-term rather than immediately available.
The story now centers more narrowly on concrete nuclear supply paths for data centers, especially the Duane Arnold restart and existing-plant deals, rather than the broader mix of nuclear possibilities. It also more clearly frames new small modular reactor concepts as longer-dated and less immediate than restarts and upgrades.
The story has broadened from a few nuclear-backed data center examples into a wider industry trend involving major tech firms, utilities, and government agencies. It now emphasizes that nuclear deals are moving into more concrete planning, while also highlighting major execution and grid risks.
