Google signs 20-year nuclear power deal
Constellation will invest $4.3B upgrading 11 reactors to add 890MW for the PJM grid under a two-decade PPA.
The Verge reported on October 7 that Google has signed a 20-year power purchase agreement with Constellation, the largest US nuclear operator, covering efficiency upgrades at 11 reactors across six sites in Illinois, Pennsylvania and New Jersey. Constellation will invest more than $4.3 billion, adding 890MW of nuclear capacity over five years — roughly one large new reactor or three small modular ones. A separate 15-year, 2,700MW energy supply agreement provides revenue floor for Constellation’s other PJM plants. Yesterday’s newswire item about a “$1B nuclear purchase” was this deal’s iceberg tip.
Why PJM
All six sites connect to PJM, the largest US regional grid (13 states plus DC) and home to Loudoun County, Virginia — the world’s biggest data-center hub. PJM is strained to breaking by AI demand: a market monitor has warned FERC that unreliable interconnections could cause blackouts, January’s “emergency” power auction was postponed by a FERC directive to shield ordinary customers from data-center-driven costs, and New Jersey rates are up 54% in five years. The deal’s essence is buying AI load a reserved seat on the grid, insulated from the congestion it creates.
Google’s emissions paradox
The framing is clean energy, but the ledger has another side: Google’s emissions rose 18% last year on a 37% jump in electricity demand, and data centers are driving a wave of new gas plants. Nuclear is the only option that simultaneously satisfies “24/7 carbon-free” and “at scale” — which is why Suncatcher is putting compute in orbit, Amazon is funding community programs, and Google is buying reactors. Three routes, one problem.
From buying power to locking it
For the industry, the signal is that PPAs have turned from ESG posture into infrastructure strategy: a 20-year term spans the life of the current data-center generation, and the 890MW is squeezed out of existing reactors — far faster than new construction. For the grid, long-term corporate contracts accelerate a two-track electricity market: AI loads with signed deals get power, while households and small businesses without them face the price increases. The next regulatory battleground is already legible.
