AI infrastructure just became a 22-year energy contract

Hyperscaler AI infrastructure is now underwritten by two-decade clean-power contracts, and the unit of account is no longer a kilowatt-hour on the spot market. It is a forward commitment to a specific plant, paired with a site that can run it cool.

Yahoo Finance's September 9, 2026 report on the Reuters wire, citing the deal Google signed with Finnish utility Fortum, is the cleanest test of that shift. The 22-year agreement covers up to half the output of the Loviisa nuclear plant, runs through its planned life extension to 2050, and ships with three new data centers on a grid that runs cold by design. Fortum's stock moved 15.5% on the news, the largest single-day gain in European utilities that day, which is the market reading the contract as structural, not a hedge.

The repeatable mechanism is straightforward. A hyperscaler needs firm, low-carbon, siting-friendly megawatts that survive regulatory and grid queues for the full useful life of a GPU cluster. Spot power and five-year hedges cannot guarantee that. A 20-year nuclear contract can. The Finland deal is the first time a US hyperscaler has crossed the Atlantic to do it, which makes Loviisa a reference price for the next round of European utility negotiations.

The bear case is live. Alphabet has already raised its 2026 capex envelope to between $195B and $205B, and AI services revenue still has to clear the buildout. Long-dated energy underwriting solves the power problem. It does not solve the demand problem.
