Constellation signs 20-year nuclear PPAs with Google and Amazon in PJM

Constellation Energy signed 20-year power purchase agreements with Google and Amazon inside a single week, and the two contracts support almost 1.1 gigawatts of nuclear expansion in PJM, according to Utility Dive. The same report puts the Google agreement at 890 megawatts and $4.3 billion of investment, a pairing that places private capital where a regulated customer would normally sit: a hyperscaler balance sheet standing in for a rate base.

PJM Interconnection is short about 6.8 gigawatts of new capacity and struggling to find resources as data center demand rises, and the grid operator will delay a planned reliability backstop procurement auction following the Federal Energy Regulatory Commission's Sept. 29 decision to only partly approve it — a delay that pushes the region's new firm supply toward private contracts while the operator's own procurement stalls.

Constellation describes the Google agreement as a direct response to PJM's Bring Your Own Power proposal and says the deal aligns with the White House's ratepayer protection pledge, an alignment easier to claim when a hyperscaler signs the invoice: grid-wide benefits funded by private entities, as the company puts it, with the customers who would otherwise carry the cost of new generation left outside the transaction.

Chief executive Joe Dominguez framed the model in those terms, saying the Google agreement can serve as a template for technology companies and energy producers working together in a way that delivers grid-wide benefits funded by private entities, and that preserving and expanding the existing nuclear fleet is critical to meeting the country's growing energy needs. That means firm, dispatchable output carried on a corporate contract instead of a regulated return, which puts it on the side of the transition trade where capacity is re-rating while pure renewables absorb margin compression.

The operating design is less familiar than the term sheet: the Google agreement incorporates load-shaping and demand-response capability so consumption can be trimmed when the grid is under stress, which gives a data center's load some of the flexibility of a dispatchable resource. The companies expect the agreement, spanning six nuclear sites, to sustain roughly 4,400 existing jobs and create about 7,200 temporary construction positions — two figures that say as much about what is being financed as the megawatt count does. Six operating sites and a workforce already in place point toward uprates and life extension rather than greenfield reactors, which the announcement's own language supports where it describes commercial investments in nuclear uprates and complicates where the headline calls the capacity new nuclear. The coverage does not break the 890 megawatts down by site or by type, so the mix remains unstated.

The technology arrangement runs deeper than a cloud contract: under an expanded five-year agreement, the two companies will apply AI to site selection, power flow modeling, permitting and interconnection planning, generation optimization and infrastructure security, with Constellation building Gemini Enterprise agentic workflows into its core operations, according to the announcement. Three of those six applications — site selection, permitting and interconnection planning — address the consent-and-queue risk that can outlast a capital raise, while the rest address how an existing plant runs. The companies' summary presents the nuclear investment and Google's technology as a single package supporting the growth of artificial intelligence and digital infrastructure, which makes the software part of the underwriting.

This route suits a grid short on capacity because uprates at licensed sites generally sit behind interconnection service that is already in place, suggesting the megawatts arrive without a new queue position or right-of-way, both of which have become binding constraints on PJM's buildout. A 20-year contract also gives the developer revenue visibility long enough to fund work at sites that already have fuel, staff and transmission in place.

Equity markets moved within hours, with Constellation shares up almost 14% in morning trading, and a move that size on a 20-year contract is a read on the counterparty as much as the megawatt — a hyperscaler underwriting nuclear operating economics for two decades carries a different risk profile than merchant output sold into PJM's auctions, and investors appear to have priced that difference immediately.

This publication has argued that grid access has become a customer class rather than a queue position, set by who can pay and through which budget line, and a 20-year nuclear PPA is that argument with a signature on it. Google's own record runs the same way: the company funded a virtual power plant built from hardware already in homes, and it has contracted 396 megawatts at Fervo Energy's Cape Station, where an initial 33-megawatt unit has begun selling power.

The Amazon contract is the thinner half of the pair in the public record: Utility Dive reports it was signed within the same week and sits inside the same roughly 1.1-gigawatt total, but gives no capacity, site list or price for it, and subtracting the 890 megawatts credited to Google leaves a little over 200 megawatts at most, arithmetic on two reported figures rather than a disclosed one. The coverage likewise gives no price per megawatt-hour, no split of the $4.3 billion between plant investment and technology spend, and no schedule for when the new output reaches the grid.

The coverage gives no new date for PJM's delayed backstop auction, and the timing of that procurement will decide how much of this becomes template. Until an auction date appears, the immediate test of Constellation's model is the next hyperscaler contract, and whether it looks like the Google agreement, with software and load-shaping attached, or like the Amazon one, whose terms the coverage does not describe.
