Fingrid's Grid Review Puts Google's €13bn Finnish Investment in the Queue
Finland's TSO is rewriting connection rules as contracted data centre capacity already exceeds forecast demand by 2030, putting Fortum's nuclear PPA at network risk.
Fingrid had signed connection agreements covering around 5 GW of data centres, more than 3 GW of electric boilers and over 4 GW of electricity storage by mid-August, CEO Asta Sihvonen-Punkka told Montel on Tuesday (2026-08-25), adding that the country's grid is congested and allocation rules are under review.6
Google's €13bn ($15.1bn) commitment, announced in September, sits behind that queue. The company will invest in Finnish AI infrastructure across 2027 and 2028 and has signed a 22-year power purchase agreement with Fortum for up to half the output of the Loviisa nuclear plant — the largest single demand addition on record for the Finnish system.7
The contracted pipeline already exceeds the demand forecast. The Finnish Data Center Association told a Helsinki conference on Wednesday (2026-05-20) that data centre power demand will more than triple to 1.2 GW by 2030, up from operational capacity of around 368 MW at the time, which represented roughly 2% of national consumption.2 Fingrid's 5 GW of signed data centre agreements is four times that 2030 forecast, which means the allocation problem precedes the Google announcement by months.6,2
Fingrid's CEO said power demand in Finland is set to rise by up to 40% by 2030.6 The Google deal is not yet in those numbers, which were anchored at mid-August.
Fortum's CEO offered a different reading in June. Speaking to Montel on Thursday (2026-06-11), he said Finland can handle "massive" power demand growth, citing land availability and grid access as the country's structural advantages.4 That was ten weeks before Fingrid's congestion warning. The utility is selling supply capacity; the TSO is rationing connection slots. Both can be right simultaneously, and for now both are.
Finland day-ahead power closed at €33.36/MWh on 2026-09-18, cheap relative to the broader European market but no longer close to the near-zero prices that drew early data centre interest. Finnish prices are not pricing scarcity; they are pricing a system with surplus generation that is running short of connection headroom, which is a different constraint.6
The supply side has its own timing mismatch. Installed wind capacity reached 9.4 GW in 2025, covering around 28% of total electricity consumption, according to Renewables Finland.1 Industry participants expect data centre demand to support further onshore wind investment. But the Loviisa PPA is nuclear, contracted for 22 years, running on a base-load clock that does not depend on wind build rates.7,1
The data centre opposition in the United States has focused on cost pass-through — whether new industrial loads pay for grid upgrades or whether those costs fall on residential customers. The US secretary of energy proposed a rule to speed up grid connections for curtailable data centres, as reported by The Economist.3 Finland's constraint is upstream of that debate. The bottleneck is not cost allocation; it is physical network capacity and the criteria by which Fingrid decides who connects first.6
The politics around that decision carry weight beyond the energy sector. Finland raised defence spending to 2.9% of GDP in 2025, and directed part of its innovation budget toward civil preparedness, infrastructure and cybersecurity, according to the Atlantic Council.5 Data centre investment now intersects with that security spending, giving opposition a national-interest framing that was not available a year ago.
Fortum is exposed at both ends. As a state-owned utility, it signed the PPA anchoring Finland's largest single new load, and it holds the generation assets contracted to meet it. If Fingrid tightens connection criteria — curtailment obligations, phased capacity releases, load-flexibility requirements — Google's €13bn commitment carries connection risk that the current day-ahead price does not price. The outcome of Fingrid's allocation review, not the headline investment figure, is what determines whether the Loviisa PPA delivers what both sides contracted for.7,64
