TikTok has unveiled a €1 billion ($1.16 billion) investment in a data center in Lahti, Finland, as it expands its European infrastructure footprint.
The project follows a similar billion-euro investment in Kouvola announced in 2025, marking the company’s second major data center development in the country and reinforcing Finland’s role in its long-term regional strategy.
Lahti Build Expands Finnish Footprint
The data center will be located in the Kiveriö district of Lahti, around 100 km (60 miles) north-east of Helsinki. The project is expected to contribute to the regional economy and support the growth of the local digital ecosystem.
Capacity and timeline have not been disclosed. However, Reuters reports the facility will launch with an initial capacity of 50 MW, with potential to scale to 128 MW.
Once operational, TikTok said the facility will strengthen its ability to store European user data locally, under strict access controls and advanced monitoring systems.
“Finland offers a unique combination of strong digital infrastructure, access to clean and reliable energy, and a highly skilled workforce,” said Christian Hannibal, head of public policy for TikTok in Finland.
“That makes it a natural choice as we continue to expand our European infrastructure and strengthen how we protect and store data locally.”
TikTok’s first Finnish site in Kouvola remains under development and forms part of the same broader infrastructure strategy, with both facilities expected to support long-term European data localization.
This latest announcement comes amid reports that TikTok has pulled back from expanding its data center footprint in Ireland, pointing to a rebalancing of capacity toward Nordic markets where power availability, land, and permitting conditions may be more favorable.
Elsewhere in the Nordic region, TikTok utilizes three Green Mountain data center buildings at the wholesale colocation company’s OSL2-Hamar campus in Norway.
Regulatory Pressure
Both TikTok investments in Finland form part of Project Clover, the company’s €12 billion ($14 billion) European data sovereignty initiative aimed at strengthening how it stores and manages data from more than 200 million European users.
Through Clover, TikTok has established a dedicated European data enclave with enhanced technical, operational, and governance safeguards.
The company has engaged NCC Group to independently oversee, verify, and track its data controls, including monitoring data flows and reporting anomalies.
The buildout reflects growing regulatory pressure in Europe, where policymakers are increasingly focused on data access, algorithm transparency, and platform risk under frameworks such as the Digital Services Act and broader EU data governance rules.
Localizing infrastructure and pairing it with independent oversight is becoming a key mechanism for demonstrating compliance and maintaining market access.
The move also follows a period of regulatory uncertainty in the US, where TikTok restructured its operations under a new joint venture model designed to address national security concerns around data access and governance.
Together, these moves underline a broader shift toward localized infrastructure, stricter oversight, and region-specific operating models.
Finland’s Data Center Momentum
Finland continues to attract data center investment due to its cool climate, abundant renewable energy, and supportive policy environment. Hyperscalers, including Google and Microsoft, have expanded significantly in the country in recent years.
In January, DayOne, the Singapore-headquartered data center operator with facilities across APAC, unveiled early-stage plans to develop a data center project in Nurmijärvi, around 30 km north of Helsinki, as it accelerates its European expansion.
According to Research and Markets, Finland’s data center market is forecast to grow at a compound annual growth rate of nearly 54% between 2024 and 2030.
