Google to Invest $15 Billion in Finland AI Infrastructure With 22-Year Nuclear Power Deal

Google is committing at least €13 billion, or about $15.1 billion, to artificial intelligence infrastructure in Finland over the next two years, marking the company's largest single investment in Europe and highlighting the increasingly important relationship between AI computing and electricity supply. The investment, scheduled for 2027 and 2028, will finance new data-centre and supporting infrastructure projects across four Finnish locations — Hamina, Kajaani, Muhos and Vaala — as Google expands capacity for services including Gemini, Search, Maps and YouTube. Alongside the technology investment, Google has signed a long-term nuclear power agreement with Finnish utility Fortum, creating a direct link between Europe's AI expansion and its race to secure reliable low-carbon electricity.

The scale of the announcement reflects a broader change in the economics of artificial intelligence. Training and operating increasingly powerful AI models requires enormous amounts of computing capacity, and the servers running those systems consume substantial quantities of electricity. For Google, expanding AI services therefore means expanding not only data centres and semiconductor capacity but also the physical energy infrastructure needed to keep those facilities running around the clock. Finland is attractive in that respect because it combines a cool climate, abundant low-carbon electricity and an established digital infrastructure ecosystem. Google's existing presence in Hamina gives it an operational base from which to expand further.

The most strategically important part of the announcement may be Google's agreement with Fortum. The companies have signed a 22-year power-purchase agreement under which Google will purchase 50% of the output from Fortum's Loviisa nuclear power plant from 2030 through 2049. Google describes this as its first nuclear power agreement outside the United States. The contract is designed to give Fortum long-term revenue certainty that can support a programme to extend the plant's operating life, ensuring that the facility can continue producing electricity for decades rather than being forced to close once its existing operating period ends.

Loviisa is already an important component of Finland's electricity system. Fortum says the plant currently employs approximately 580 people and supplies around 10% of Finland's electricity. Without the planned lifetime-extension investment programme, the company says the plant would not be able to continue operating beyond 2030. Google's agreement therefore goes beyond supplying electricity to one corporate customer: it potentially helps keep an existing nuclear asset operating and contributing to the wider Finnish grid for a much longer period. Fortum shares jumped more than 8% following the announcement, underscoring how significant investors considered the agreement for the Nordic utility.

Google is also planning to use renewable electricity as part of the expansion. The company announced additional power-purchase agreements with onshore wind developers Valorem and Suomen Hyötytuuli, taking the total new-to-the-grid onshore wind capacity supported by Google's Finnish agreements to 629 megawatts. It is also contracting a 94-megawatt battery system near its Kajaani site, scheduled to become operational in late 2027. The battery is intended to provide flexibility to the electricity system and help balance supply and demand during periods when wind production is low.

This model reflects a significant evolution in how large technology companies approach energy. Instead of simply purchasing power from the existing grid, hyperscalers are increasingly becoming long-term partners in energy markets. They are signing power contracts, supporting new generation, investing in batteries and working with utilities to strengthen transmission networks. The objective is partly corporate: ensuring that data centres have access to enough electricity. But it also changes the economics of new energy projects because a technology company with a long-term power contract can provide developers with a predictable customer and revenue stream.

Finland offers several advantages for this strategy. Its northern climate can reduce cooling requirements for data centres, lowering one of the major energy costs associated with large-scale computing. Google's Hamina facility has also used seawater-based cooling and heat recovery, with excess heat distributed to local homes and businesses. Google says its decade-plus presence in Hamina has included partnerships with Finnish suppliers and more than 40 social and community organizations, giving the company an established local ecosystem as it expands.

The new investment will extend Google's footprint well beyond Hamina. The company plans infrastructure projects in Kajaani, Muhos and Vaala, including locations in northern Finland where existing grid capacity and proximity to low-carbon electricity can reduce the need for some new transmission investment. Google says it is working with Fingrid and Business Finland to identify infrastructure locations that are compatible with the Finnish electricity system. The approach is intended to align new data-centre demand with areas where electricity infrastructure is already available or can be expanded efficiently.

The economic impact could be substantial. Google estimates that its Finnish infrastructure programme will contribute roughly $3.6 billion to Finland's gross domestic product during construction. The company expects the initiative to support more than 37,000 jobs during the initial construction phase and around 7,000 jobs annually once the facilities are operating. Those numbers include the wider economic activity created through construction, suppliers and supporting infrastructure rather than implying that Google itself will directly employ all of those workers.

For Finland, the agreement comes as European governments compete to attract AI infrastructure investment while trying to limit the pressure that rapidly growing data centres can put on national electricity systems. AI facilities can consume huge quantities of power, and sudden concentrations of demand can require expensive grid upgrades. Google's approach of pairing new computing infrastructure with long-term energy commitments could provide a model for other countries seeking to capture the economic benefits of AI without allowing data-centre growth to destabilize electricity markets.

The nuclear component is particularly significant because it reflects a broader shift in the technology industry's attitude toward atomic energy. For years, renewable power-purchase agreements were the primary tool used by major technology companies to reduce emissions from electricity consumption. More recently, the rapid growth of AI has highlighted the limitations of relying exclusively on variable renewable generation. Wind and solar power can be highly competitive but fluctuate with weather and time of day. Nuclear plants, by contrast, can provide steady low-carbon electricity and operate continuously, making them attractive for data centres that cannot tolerate interruptions.

Google's Fortum agreement also signals that extending the life of existing nuclear plants can be a practical part of the AI energy strategy. Building new reactors takes many years and requires substantial capital, regulatory approvals and construction capacity. Keeping functioning reactors in operation for longer can potentially add reliable electricity sooner. Fortum and Google are going further by signing a memorandum of understanding to explore additional electricity generation and flexibility capacity, including the potential development of new nuclear reactors at the Loviisa site.

That does not mean Finland is becoming dependent on Google for its electricity supply. The companies say the structure of the partnership is designed to add low-carbon energy and strengthen the Finnish electricity system as Google's demand grows. Google is also supporting grid enhancements and initiatives intended to maintain energy affordability. Its new battery project and wind partnerships are designed partly to help the broader system balance variable renewable generation.

For investors, the announcement illustrates how the AI boom is expanding far beyond semiconductor manufacturers and cloud companies. Utilities, nuclear operators, renewable-energy developers, battery manufacturers, grid-equipment suppliers and transmission companies are all becoming potential beneficiaries of the massive infrastructure cycle created by AI. Electricity availability is increasingly emerging as a competitive advantage for data-centre operators, which could make regions with abundant reliable power more valuable in the global AI race.

Google's decision also reinforces the idea that energy strategy is becoming part of Big Tech's core infrastructure planning. The company is effectively securing a portion of the electricity required for future computing capacity years in advance. The 22-year nuclear agreement extends well beyond Google's immediate investment window of 2027 and 2028, showing that the company is planning its AI infrastructure around energy availability over decades rather than quarters.

There are, however, risks. The economics of data centres depend on continued demand for AI services, while electricity markets are sensitive to regulatory changes, transmission constraints, construction delays and shifts in energy prices. Nuclear power projects also face complex technical and regulatory requirements. Google's long-term commitments therefore represent both an opportunity and a substantial bet: that demand for AI computing will remain strong enough to justify the physical infrastructure being built today.

The Finland announcement is ultimately less about one data centre or one power contract than it is about the changing relationship between technology and energy. The AI industry has entered a phase in which computing power is constrained not only by chips and servers but also by access to dependable electricity. Google's decision to combine a $15 billion infrastructure expansion with nuclear, wind, battery and grid investments shows how technology companies are responding.

For Finland, the deal brings investment, jobs and a deeper role in Europe's AI economy. For Google, it provides additional capacity in a country with strong low-carbon energy credentials and favourable data-centre conditions. For the wider market, it offers another indication that the next stage of the AI boom could become as much an energy-infrastructure story as a software or semiconductor story.

Investors will watch the expansion schedule at Hamina, Kajaani, Muhos and Vaala, progress on the Loviisa lifetime-extension programme, and the development of Google's additional wind and battery projects. The bigger market question will be whether other technology companies sign comparable long-term nuclear contracts as AI data-centre electricity demand continues to rise across Europe and the United States.
