TerraPower plans to announce a second nuclear plant serving a data center this year, targeting a 2027 groundbreaking.

TerraPower expects to announce its next nuclear project during 2026, with the plant planned to serve a data center. Chief Executive Officer Chris Levesque said the company is targeting a 2027 groundbreaking for the second project.

The Bill Gates-backed company was described as the only U.S. company currently building a utility-scale nuclear power plant. The planned data-center project would be separate from that first plant and remains at the pre-announcement stage described by management.

Levesque declined to identify the data-center customer. The source also does not provide the project’s location, generating capacity, reactor configuration, contract structure, power-delivery schedule, construction cost, financing, or regulatory status.
