Google announced a €1 billion expansion of its data-center campus in Hamina, Finland, on 20 May 2024. The announcement was reported in dollar terms in some headlines, but Google’s primary figure was in euros; no dated exchange rate is applied here. The project was expected to add about 100 permanent full-time jobs, support thousands of construction-related jobs, and provide recovered data-center heat for Hamina’s district-heating system.
What Google announced
The project is an expansion of Google’s existing Hamina campus, not a consumer product or a separate national data-center network. Business Finland said the investment would lift Google’s total investment in Finland above €4.5 billion. That includes about €3.5 billion invested in the Hamina data center and related infrastructure since 2009.
Google bought the former Summa paper mill and neighboring land in 2009 and opened its first Hamina data center in 2011. Google’s Hamina location information lists construction of a seventh data center announced in 2024.
Investment, jobs and schedule
| Measure | What was announced or estimated | Qualification |
|---|---|---|
| Expansion investment | €1 billion | Google announcement, 20 May 2024; the figure is denominated in euros |
| Total Google investment in Finland | More than €4.5 billion | Business Finland’s 2024 figure, including earlier investment |
| Permanent employment | About 100 new full-time jobs | Expected addition; the campus had about 400 full-time and contractor roles at announcement time |
| Direct construction jobs | About 1,900 per year | Business Finland/Deloitte estimate, averaged over the next two years |
| Indirect construction jobs | About 1,650 per year | Business Finland/Deloitte estimate, averaged over the next two years |
| Induced jobs | About 640 per year | Business Finland/Deloitte estimate, averaged over the next two years |
| Service readiness | Toward the end of summer 2025 | Yle’s contemporaneous forecast in May 2024, conditional on construction proceeding smoothly; it is not proof that the facility was completed |
The construction estimates are annual averages for a two-year period, not a promise of permanent positions. The roughly 100 full-time roles are the more relevant figure for the campus’s longer-term operating workforce.

Where the Finnish data center is located
The campus is in Hamina, in Finland’s Kymenlaakso region on the Gulf of Finland. Its industrial heritage matters: Google repurposed the former Summa paper-mill site rather than establishing the campus on an undeveloped location. Hamina is also the home of Haminan Energia, the city-owned energy company involved in the heat-recovery project.
Cooling, electricity and environmental design
Seawater cooling
Google says the Hamina site uses seawater from the Gulf of Finland for cooling. That design uses the local coastal environment as part of the facility’s cooling system, although the announcement does not provide a project-specific water-consumption figure or a comparison with alternative cooling systems.
Carbon-free energy share
Google’s location information says Finland achieved 98% Google carbon-free energy in 2023. That is a country-level figure for Google’s Finnish operations and does not mean every hour of the Hamina expansion will be powered entirely by carbon-free electricity.
How the waste-heat system is intended to work
Google and Haminan Energia planned to capture excess heat from the data center and send it into Hamina’s district-heating network. Business Finland and Google said the recovered heat could equal about 80% of Hamina’s annual district-heating demand, serving homes, schools and public-service buildings.

Google said the heat would be supplied free of charge apart from a nominal €1 plus VAT annual administrative fee. The project was expected to begin contributing by late 2025. That is a planned delivery target, not confirmation that the network was already receiving the stated volume.
Data centers produce substantial low-grade heat because servers operate continuously. A district-heating connection can make that heat useful only when collection equipment, transmission pipes and the receiving network are designed and operated together. The 80% figure is an estimate of annual district-heating demand, so actual output can vary with weather, server load, maintenance and seasonal heating needs.
What the expansion could mean for Finland and Hamina
Local employment
Construction creates a temporary surge across contractors and suppliers, reflected in the Business Finland/Deloitte estimates. Once the new capacity is operating, the expected employment effect is smaller but more durable: about 100 additional full-time positions on top of the campus’s existing workforce.
Regional infrastructure and tax base
A €1 billion industrial expansion can generate demand for construction, electrical, engineering, security, facilities and energy services. The available announcement does not quantify tax receipts, household-income gains or the final split between Finnish and international suppliers, so those effects should not be treated as measured outcomes.

Heat for public buildings and households
If the planned connection reaches its design estimate, Hamina’s district-heating system could rely far less on other heat sources during operating periods. The benefit is local: it concerns customers connected to Hamina’s network, not Finnish households generally.

Why the currency wording matters
“$1 billion” is a headline convention for this story, while the primary announcement used €1 billion. Exchange rates move over time, so converting the amount without stating a date can create a misleading impression of the project’s value. For comparing this project with other data-center investments, use the original euro figure or identify the conversion date and rate.
The Bottom Line
Google’s Finland project is a €1 billion expansion of its Hamina data-center campus, expected to add about 100 permanent jobs and support thousands of annual construction-related jobs. Its distinctive local feature is planned heat recovery for Hamina’s district-heating network, with a design estimate equal to roughly 80% of annual demand; completion and real-world output were not established by the May 2024 announcement.
