TikTok building second Finland data centre
TikTok plans a second billion‑euro data centre in Lahti, Finland, moving more European user data onto the continent as part of a data‑localisation push and signalling heavy infrastructure investment for consumer apps. The project underlines that large consumer platforms are now judged on hard infrastructure issues like data residency and scalable power capacity. (investing.com)
TikTok is spending another 1 billion euros on a data centre in Lahti, Finland, less than a year after it announced its first Finnish site in Kouvola. The new Lahti site starts at 50 megawatts and can scale to 128 megawatts, which puts it in the size range of a major cloud campus, not a simple backup room. (newsroom.tiktok.com, usnews.com) This is not TikTok buying office space. A 50 megawatt data centre is an electricity-hungry warehouse full of servers, and 128 megawatts is enough power to make grid access and long-term energy supply part of the business plan from day one. (usnews.com, powermag.com) The reason TikTok is doing this in Europe is simple: European regulators care where user data lives and who can reach it. In May 2025, Ireland’s Data Protection Commission fined TikTok 530 million euros and said transfers of European Economic Area user data to China broke the General Data Protection Regulation. (dataprotection.ie) That ruling did not ban TikTok in Europe, but it did order corrective steps and said transfers to China had to be suspended if TikTok did not bring its processing into compliance within six months. The pressure point was remote access by staff in China, not just the physical location of the servers. (dataprotection.ie) TikTok’s answer is a program called Project Clover, a multibillion-euro effort to keep European user data inside Europe and wrap it in tighter access controls. TikTok says its Norway site at Hamar came fully online in 2025, its first Finland investment was announced in May 2025, and the new Lahti build is the second billion-euro Finnish step in that same plan. (tiktok.com, newsroom.tiktok.com, newsroom.tiktok.com) Finland is not a random pin on a map. TikTok says it chose Lahti for secure digital infrastructure, and data-centre developers keep choosing Finland because cold weather cuts cooling costs and the grid can support large facilities powered by low-carbon electricity. (newsroom.tiktok.com, dayonedc.com) Lahti and Kouvola also sit close enough to work like a cluster instead of isolated outposts. Reports on the Finnish buildout place the two cities roughly 60 kilometers apart, which makes it easier to share staff, network links, and resilience planning across both sites. (afterdawn.com, newsroom.tiktok.com) The bigger shift is that consumer internet companies now have to look like infrastructure companies. A video app with 150 million-plus European users is being judged not only on its feed and moderation, but on substations, server halls, audit controls, and whether regulators believe the data can stay under European rules. (newsroom.tiktok.com, dataprotection.ie) That is why a Finland construction story is really a power-and-sovereignty story. TikTok is spending data-centre money to solve a trust problem, and Europe is forcing one of the world’s biggest consumer apps to prove itself with concrete, steel, and megawatts.
