Holtec, Constellation and NextEra plan 2.25 GW of nuclear restarts

Three previously closed US nuclear plants are being prepared for recommissioning, restoring a combined 2.25 GW as AI and data-centre power demand rises. The DOE is providing up to $4.4 billion in loans, with Microsoft and Google backing the projects via long-term power purchase agreements.

• Palisades (800 MW) in Michigan targets a return around March 2027
• Constellation is spending about $1.6 billion to restart Three Mile Island Unit 1 (835 MW)
• Duane Arnold (615 MW) in Iowa is expected back in Q1 2029
• The US DOE is providing up to $4.4 billion in loans for the three projects
