Google announced a two-year €13 billion investment in Finnish AI infrastructure, anchored by long-term nuclear power purchase agreements with utility Fortum. The capital commitment — equivalent to $15 billion at current exchange rates — will fund data center expansion in the Hamina region and marks the first time a U.S. hyperscaler has structured nuclear procurement outside North America for inference workloads.

The nuclear offtake agreements span two decades and will draw from Finland's existing fleet, including the 1,600 MW Olkiluoto 3 reactor that reached full commercial operation in April 2023. Google will receive baseload capacity beginning Q4 2025, with phased expansion through 2027 as Hamina's cooling infrastructure scales. Fortum declined to disclose per-megawatt pricing but confirmed the contracts include inflation indexing tied to European wholesale power markets. The €13 billion figure includes land acquisition, cooling systems, and fiber backhaul to Stockholm and Frankfurt peering points.

This matters because Google is solving the same constraint throttling U.S. data center deployment — grid reliability for 24/7 inference clusters — but moved faster in a jurisdiction with surplus nuclear capacity and permitting velocity. Finland's energy mix is 34% nuclear, the third-highest share in Europe, and Olkiluoto 3 alone added more baseload capacity than any U.S. nuclear plant commissioned since Watts Bar 2 in 2016. The deal structure bypasses the 8-12 year timelines facing U.S. hyperscalers attempting small modular reactor partnerships, giving Google a material advantage in European GPU cluster density through 2029.

The choice of Hamina is precise. Google has operated a seawater-cooled facility there since 2011, giving it established fiber routes and thermal discharge permits that competitors lack. The new buildout will add an estimated 400 MW of AI-specific compute, roughly 3x the inference capacity of Google's Iowa facilities. European regulators have signaled they will exempt AI infrastructure from certain carbon accounting rules if power is contractually tied to nuclear or hydro, a carve-out that makes the Fortum deal more economically durable than U.S. wind-and-solar PPAs currently under renegotiation.

Operators should track three follow-on events. First, whether Microsoft or Amazon announce competing Nordic nuclear deals within 90 days — both have scouted Norwegian hydro partnerships but lack Finland's regulatory clarity. Second, whether Google extends the Fortum contracts beyond 20 years, which would signal confidence in post-2040 European AI demand and imply they expect current LLM architectures to persist. Third, watch Finnish parliamentary debate in Q3 2025 on permitting for a fourth domestic reactor; passage would validate hyperscaler demand as a driver of European nuclear economics.

The €13 billion commitment is larger than Google's cumulative European data center spend from 2019-2023 combined, compressed into 24 months. That velocity is the signal.
