Google plans to invest at least €13 billion in Finland during 2027 and 2028, linking a major expansion of its digital infrastructure with agreements to secure electricity. The company announced the plan on September 9, 2026, covering data centres, supporting infrastructure and partnerships in Hamina, Kajaani, Muhos and Vaala.
The public-interest question extends beyond computing: how will this expansion fit into the electricity system used by households and other businesses? The accompanying energy arrangements provide some detail, although the announcements do not establish what consumers will ultimately pay.
A long-term customer for an existing nuclear plant
Finnish energy company Fortum has signed a 22-year power purchase agreement with Google. Such a contract gives a generator a long-term customer for electricity. Fortum says the agreement provides revenue certainty to support investment in extending the operation of its Loviisa nuclear plant through 2050.
Under Fortum’s published terms, supply starts at a smaller level in 2028 and reaches 50% of the plant’s capacity for 2030 through 2049. Google is buying electricity under the arrangement; ownership of the plant remains with Fortum.
The companies are also exploring potential business models for new reactors at Loviisa. That work remains exploratory. It should not be read as confirmation that new reactors have been approved or will be built.
Wind and batteries also feature in the plan
Google’s separate energy announcement says additional wind agreements bring the new onshore wind capacity it has contracted in Finland to 629 megawatts. It also describes a 94-megawatt battery system near Kajaani, expected to begin operating in late 2027.
The battery is intended to help balance the grid as electricity supply and demand change. Google says it is working with grid operators to explore temporarily reducing data-centre demand during periods of grid stress. That wider work is described as a feasibility exercise, rather than a commitment already in operation across the new sites.
What remains to be demonstrated
Google presents affordability as an objective of its energy programme. Future household bill savings are not established by these announcements. Its employment projections likewise describe jobs expected to be supported across the economy, rather than confirmed Google vacancies.
The next useful evidence will be delivery: construction progress, energy projects entering service and measured outcomes for the wider electricity system.
