Constellation and Google partner on nuclear uprates

· Climate · United States

Constellation Energy, the biggest US nuclear plant operator, said it would work with Google on nuclear uprates, adding carbon-free power capacity without building new reactors. The move supports the Trump administration's goal of adding 5 gigawatts of carbon-free nuclear capacity by 2029 without deploying a single new reactor. Big Tech's growing electricity demand, especially from AI data centers, is driving interest in existing nuclear plants as a source of firm, clean power.

Why it matters：Uprates offer the fastest near-term route to new firm clean power, and Big Tech's willingness to fund them could reshape how data center demand is met.

Key points

  • Constellation is the largest US nuclear operator.
  • The administration targets 5 GW of added carbon-free nuclear capacity by 2029.
  • No new reactors would be built under the plan.
