Why Finland, and why now
The cheapest industrial power in the EU, a grid that retired coal four years early, and five gigawatts of data-centre demand forming. The numbers, and the part they leave out.
When an international investor asks why Finland, the honest answer starts with a Eurostat table: in the second half of 2025, industry paid less for electricity in Finland than anywhere else in the EU. The spot market averaged roughly 41 €/MWh across the year, down on the year before, with only hydro-heavy Sweden and Norway cheaper in Europe. Cheap power here is not a phase. It is structure.
Where the power comes from
The structure is simple to describe. Olkiluoto 3, Europe's most powerful reactor, runs at the base of the system, and wind has grown from a tenth of consumption in 2021 to nearly thirty percent today. Fossil fuels supplied under five percent of generation in 2024, and the last coal plants closed in spring 2025, four years ahead of the legal deadline. Carbon neutrality by 2035 is not a pledge but a statutory obligation, and the power system is arriving early.
Abundance has a flip side that the brochures skip: volatility. Finland logged more negative-price hours than any other European market in 2023 and 2024, and the spread between windy and still hours keeps widening. For a generator, that is a discipline. For storage, it is the business case, which is why battery projects sit where the volatility does.
Where demand is coming from
Demand has noticed, and the numbers are almost comically large. Developers have filed grid-connection enquiries with Fingrid totalling more than 50,000 megawatts, against a national peak load of about 15,000. Fingrid's own planning chief calls the figure staggering and is blunt that most of these will never be built; his realistic estimate is that around a tenth materialise, which would still add some 5,000 megawatts, a third of today's peak. Microsoft's first Finnish region is under construction in Kirkkonummi, with its waste heat contracted into district heating, and in June 2026 the company signed a preliminary agreement for a second site in the GigaVaasa industrial zone on the west coast. Google, which has cooled its Hamina campus with seawater since 2009, bought a nine-hundred-hectare site in Vaala, in central Finland, early this year. Hydrogen and industrial electrification queue behind.
Policy moves too, and not only one way. From July 2026, data centres lose Finland's lower industrial electricity tax class, a change worth about 47 million euros a year to the treasury. It does not change the fundamentals. It does reward the developer who reads Finnish policy in the original and hears about drafts before they become law.
How projects get built
What the numbers leave out is how projects actually get built. Finland is a single price area with a transparent grid operator, which is exactly why the connection queue is crowded: capacity, not capital, is the scarce input, and it goes to projects that are real. And every route to ready-to-build runs through a municipality. There are over three hundred of them, each with a planning monopoly and its own habits. Finns appreciate direct talk and kept promises, and word travels fast. That sentence has survived every rewrite of this site, because it is the operating manual.
Our answer to why now is the portfolio: about 1.5 GW in development across some twenty sites in battery storage, solar and data-centre land, with part of the solar portfolio in a project development partnership with FRV. The public projects are on the map. The rest we share individually: write to Mikke Vepsäläinen.
