Google contracts for 3,590 MW of power from Constellation Energy in the US' largest power grid, with new nuclear energy accounting for ~25% of that supply
Google (GOOGL.O) has contracted for 3,590 megawatts of power from Constellation Energy (CEG.O) in the US' largest power grid …
Context & Ripple Effects
Google has been assembling a diverse power-procurement portfolio: a 500 MW small-modular-reactor agreement in 2024, hydroelectric contracts in 2025, and geothermal supply for Nevada data centers in 2026. The Constellation contract is a substantially larger commitment within a single grid.
It also follows demand-response agreements with five utilities covering up to 1 GW of load reduction. Together, the supply contract and load-flexibility arrangements make electricity availability an operating input for Google rather than a background utility expense.
First-order effects
- Google secures 3,590 MW of contracted power from Constellation in the largest US power grid, with roughly one-quarter of the supply tied to new nuclear energy.
- Constellation gains a major committed customer for its power portfolio, including the new nuclear portion of the contracted supply.
Second-order effects
- Google can pair long-term supply procurement with its existing demand-response arrangements, giving it both contracted capacity and a mechanism to reduce consumption during grid peaks.
- Constellation’s nuclear-backed offer becomes a direct alternative within Google’s procurement mix to the hydro, geothermal and future small-reactor agreements Google has already signed.
Third-order effects
- Large data-center buyers are increasingly treating contracted generation and flexible demand as complementary forms of capacity, concentrating more bargaining power in long-term power agreements.
- If similar contracts proliferate, access to firm generation—rather than only data-center sites or computing hardware—will more directly determine where large-scale compute can be added.
The trend: Power procurement is becoming a form of compute-capacity planning, with large buyers combining firm clean generation contracts and controllable load.
