Finland taxed the electrons

Google owns a 1,400-hectare plot across Kajaani and Muhos in northern Finland, land bought for a data-center project once valued near a billion euros. As of this month that project is on hold. On 1 July 2026 Finland moved data centers out of its lower electricity-tax category and into the general one, taking the rate from 0.05 to 2.24 cents per kilowatt-hour, an increase of 2.19 cents on every unit, close to 44 times the old charge.

Google told the Finnish government during the spring consultation that it had not yet made an investment decision for the sites and that regulatory stability and predictable operating conditions ranked among the factors that would decide it. The government, aware the relief was what drew hyperscalers north in the first place, says it is preparing a new support scheme aimed at value-added data centers for the autumn. That leaves a gap: the higher tax is already live, the replacement incentive is not.

Germany taxed the waste heat

Germany did not raise a power tax; it raised a build standard. Under the Energy Efficiency Act, any data center above 300 kilowatts of connected load that starts operating from 1 July 2026 must reuse at least 10 percent of the heat it produces, a share that climbs to 15 percent in 2027 and 20 percent in 2028. Operators meet it by piping heat into a district network or reusing it on site, which means the choice of location now depends on whether there is a heat customer nearby.

The law passed in 2023, but this is the month it starts shaping concrete. Frankfurt, where data centers already draw up to 40 percent of the city's power, is exactly where the rule bites hardest: land near existing heat networks gains value, and a greenfield site with no offtaker becomes a harder business case. It is a capital cost baked into the design, not a line on the monthly bill.

The map, not the model, now sets the bill

Put the two together and a pattern appears that no single announcement spells out: within one internal market, the running cost of an identical rack now swings sharply with the border it sits behind. Finland priced the electricity; Germany priced the heat. Sweden's northern hydro, France's nuclear baseload and Spain's cheap solar suddenly look more attractive, not because the hardware changed but because the policy did. In the UK, where grid-connection queues already stretch years, the same logic drives siting toward Scotland and the North. Capacity follows that math, and it is already moving.

For an operator the practical response is to model total landed cost per country before signing land: the electricity-tax band, the waste-heat capex, the grid-connection queue and the local carbon rules, not just the headline power price. The uncomfortable implication is a sovereignty one. If the friendliest mix of cheap power and spare grid keeps sitting in a handful of regions, Europe's AI capacity concentrates there, and some of the friendliest options sit outside the EU entirely.
