tl;dr: Google is investing €13bn in Finland—its largest single European investment—to build three new data centres, expand its Hamina site, and power growing AI demand. As part of the deal, Google signed a 22-year contract with utility Fortum to purchase up to 50% of the output from the Loviisa nuclear plant, which supplies about 10% of Finland's electricity. Finland's cool climate, low-carbon power, and uncongested grid have made it a magnet for data centre investment, with TikTok also announcing a $1bn facility there this week.
