Where it stands

Google and Fortum signed a 22-year nuclear power purchase agreement on 9 September 2026 as Google announced €13 billion for Finland’s AI infrastructure. The investment is planned for 2027 and 2028. Power purchases from the existing Loviisa plant begin at a smaller level in 2028, reaching 50% of capacity for 2030–2049. Long-term sales give Fortum more certainty to fund continued operation and upgrades. This is a future electricity-supply arrangement, not the opening of a new reactor. The companies will also explore additional energy projects, whose construction is not assured by this agreement.

Background

Data centres run large numbers of computers and need electricity for both processing and cooling. Expanding AI services therefore creates a need for dependable power alongside new buildings and servers. Nuclear plants can provide low-carbon electricity without depending on sunlight or wind conditions. But keeping an ageing plant operating requires licences, maintenance and investment. A long-term buyer can make that investment easier to plan by providing predictable demand. Google’s agreement links its future electricity needs with work to extend the life of Fortum’s existing Loviisa plant.

How it developed

Earlier context: extending Loviisa’s operating life

How it started
An existing nuclear plant needs investment to keep operating

Fortum’s Loviisa plant has 2 reactors that began commercial operation in 1977 and 1980. The plant supplies about 10% of Finland’s electricity. Its operating licences extend to 2050, but continued operation still needs investment in the existing facility. Fortum estimates a life-extension programme of about €1 billion. Securing a long-term customer helps provide the revenue certainty needed to plan that work.

9 September 2026: contract signed; supply begins in 2028

New fact
The contract starts in 2028 and expands from 2030

The agreement signed on 9 September 2026 runs for 22 years. Google’s purchases start at a smaller level in 2028 and cover 50% of Loviisa’s capacity during 2030–2049. Fortum says the arrangement supports lifetime-extension investment and an expected 10-megawatt capacity increase. Google’s separate €13-billion programme covers AI infrastructure in Finland during 2027 and 2028. The companies also agreed to explore further nuclear, renewable and flexible energy projects. Those exploratory plans are not approvals to build additional reactors. The purchase agreement concerns electricity; it does not transfer ownership of half the plant to Google.

Why it matters for UPSC

GS3 · Energy securityGS3 · Infrastructure

For GS3, connect AI infrastructure with energy security, low-carbon electricity and investment planning. Distinguish a signed power contract from an operating new plant. Nuclear power is low-carbon, but is not generally classified as renewable energy.

Key terms

Data centreA facility housing computers, storage and network equipment that provide digital services. Running the computers produces heat, so cooling also uses resources. AI expansion therefore needs a power and cooling plan as well as computing hardware.

Power purchase agreementA contract setting terms for buying electricity over a specified period. A long-term buyer gives a generator more predictable demand and revenue. Signing such a contract is different from immediately receiving all the contracted electricity.

Nuclear lifetime extensionWork that enables an existing nuclear plant to continue operating beyond its earlier planning horizon, subject to regulatory approval and safety requirements. It can involve maintenance and equipment upgrades. It is not the same as constructing a new reactor.

Low-carbon electricityElectricity produced with comparatively low greenhouse-gas emissions over its life cycle. Nuclear power belongs in this category. Low-carbon does not mean impact-free: safety, waste management and other environmental responsibilities remain.

Renewable energyEnergy from naturally replenished sources such as sunlight and wind. Nuclear power uses mined fuel and is not generally classified as renewable. A clean-energy programme can include both renewable generation and low-carbon nuclear power.

Capacity and generationCapacity describes how much power a facility can supply at a given moment, commonly measured in megawatts. Generation describes electricity produced over time. Buying output associated with plant capacity does not mean buying ownership of the plant itself.

Grid and flexibilityThe grid carries electricity between producers and users. Flexibility helps balance supply and demand as conditions change, using tools such as storage or adjusted consumption. A data centre’s supply contract does not eliminate the need for a functioning shared grid.

Memorandum of understandingA document recording intentions for cooperation. Here, further energy projects are to be explored. That stage must be distinguished from a final investment decision, construction approval and an operational facility.
