Google’s 3,590 MW Contract Isn’t a Grid Connection

Google has contracted for 3,590 MW from Constellation Energy. It has also signed agreements with five US utilities to reduce up to 1 GW of data-center demand at peak times. The company arranging for more electricity is preparing to use less when the grid is strained.

Google can secure future generation years before its electricity can reach a particular building. Utilities must also plan for the hours when that building competes with other customers. Those demands now shape Google’s power deals alongside the price and source of supply.

Google’s contracts have outgrown renewable matching

In 2021, Google said its renewable procurement should help create new resources rather than assume existing supply was fixed. That addressed how to add cleaner electricity. It left open when a particular data center could draw from a constrained grid.

In July 2025, Google signed two 20-year hydroelectric power-purchase agreements with Brookfield, worth $3 billion and covering up to 670 MW. In October, Google and NextEra Energy signed a 25-year supply agreement that includes restarting the 615 MW Duane Arnold nuclear plant in Iowa. Both tied Google to named assets for periods much longer than a typical technology product cycle.

Google’s Constellation agreement reaches further into planned generation: roughly 25% of its 3,590 MW is expected from new nuclear supply. The contract’s total is not the capacity of new reactors, and those reactors have yet to operate. Google has arranged future output before the computing demand arrives.

A data-center site inherits its grid’s constraints

Google said it would invest $17 billion in its first Wyoming data center, pay for all the electricity the project uses and form a Community Council to address concerns about local growth. The commitments belong together. Paying for consumption addresses who bears the bill; it does not settle when power can be delivered or whether the community accepts the development around it.

Google also bought Crusoe’s southeast Wyoming data-center site after Crusoe reportedly failed to secure Google as a customer for the project. By buying the site instead, Google took on the challenge of turning a location into a powered campus.

Some developers have turned to aeroderivative turbines or diesel generators rather than wait for conventional connections. On-site generation can change a project’s schedule, but it brings equipment, permitting and fuel questions of its own. The power-delivery problem is the gap between capacity a company has arranged and capacity a building can use.

Google is offering to manage demand, not just buy supply

PJM Interconnection proposed requiring large data centers either to bring their own generation or curtail consumption to help avert large-scale outages. A data center that cannot bring enough power to a stressed system may still be easier to connect if it can reliably reduce its load when the system needs relief.

Google’s demand-response agreements with five US utilities cover up to 1 GW of potential reductions in data-center consumption during peak periods. Google, Nvidia and Emerald AI later launched an alliance focused on data centers adjusting electricity use to grid conditions. These arrangements give utilities a way to change demand when another generation contract cannot help in time.

Potential curtailment is not a measured gigawatt reduction. Google still has to make those reductions dependable enough for a utility to count on them. Its buildings must be able to change their electricity use when other customers need the grid.

Nuclear customers can support new supply—or claim existing supply

Owners of roughly a third of US nuclear plants were reported to be in talks with technology companies in 2024. Existing plants already have generating equipment, operating histories and grid connections. Buying their output can give a data-center customer a long-duration arrangement without waiting for a new plant, though it does not necessarily add electricity to the system.

Meta moved on both sides of that distinction. Its agreements with Vistra, TerraPower and Oklo cover purchases from existing plants and support for reactor projects, targeting up to 6.6 GW by 2035. Amazon signed a 20-year agreement to buy 690 MW from Constellation, supporting more than $3 billion of investment in Maryland. A long contract gives a generator a customer against which to plan; the generator still has to deliver the capacity.

Google’s other generation deals put dates on the wait. It agreed to buy the initial output of a 1.6 GW Arkansas solar project if it becomes operational as planned in 2029, and up to 150 MW of geothermal electricity for Nevada data centers beginning in 2028. A buyer planning a new campus has to work with those scheduled starts, not just the projects’ capacity figures.

The power position sits on the balance sheet

Google can reserve future output, but it cannot control every generator’s timetable or the pace of data-center demand. It has also provided a credit backstop to support financing for a TeraWulf data-center project with Anthropic in Kentucky, planned to come online in the second half of 2027. Google is backing construction involving another AI company as well as securing power for its own sites.

Those deals sit within much larger spending plans. Bloomberg reported that Alphabet, Meta, Microsoft, Amazon and Oracle had more than $3 trillion in collective future AI spending commitments, including more than $1 trillion at Alphabet. By May 2026, reported hyperscaler unsecured-bond issuance had reached $155 billion for the year, more than 45% above total issuance in 2025. The cost of insuring against debt defaults at Alphabet and four other major hyperscalers also reached its highest level since 2021. Investors may finance a long buildout and still charge more for its risk.

Customers face that exposure, too. OpenAI was reportedly hiring a lead to hedge electricity costs across its data-center portfolio. Securing a facility does not fix the price of the power it will use.

In Wyoming, Google has promised to pay for every watt its planned building consumes. The promise can be signed years in advance. The wire still has to deliver each watt.
