TikTok announced the next stage of its expanded investment in Europe with a USD 1.2 billion data center project in Lahti, Finland. The new data center will store TikTok's EU user information separately from the company's home base in China, in compliance with EU directives.

Project Clover Expansion

The development is part of Project Clover, an initiative designed to store EU user data outside of the company's home base in China in compliance with EU directives. The project is TikTok's USD 1.2 billion  initiative that was developed in order to align with rising demand from EU regulators about how TikTok manages data collection.

The new data center is TikTok's second in Finland, following its Kouvola development, which opened last year. The Lahti center will host EU user info and ensure that the company doesn't need to transfer information back to China for processing.

Location and Economic Impact

The data center will be located in the Kiveriö district of Lahti and will contribute to the regional economy and support the growth of the local digital ecosystem, according to TikTok. Once operational, the Lahti data center will strengthen TikTok's ability to support the default storage of European user data in Europe, under strict access controls and advanced monitoring systems.

The company hasn't shared further information on production plans, but Data Center Dynamics reported that China-based data center company DayOne is developing a 128MW campus in Lahti, which is presumably linked to TikTok's latest announcement.

Regulatory Background

In May 2025, TikTok was fined 530 million euros for infringements of GDPR regulations relating to the transfer of EU user data to China. The ruling also dictated that TikTok would be required to revise its data processes for assessment by EU authorities moving forward.

Given the scope of the penalty and the business opportunities for the app in the region, the expanded investment in EU data centers makes sense and will ensure that TikTok can continue to grow in the market without needing to rely on external data processing.

Broader Infrastructure Development

Project Clover has also seen the activation of new data centers in Norway and Ireland, with its Finland-based projects providing more capacity to keep EU user data isolated. The expanded infrastructure investment demonstrates TikTok's commitment to maintaining compliance with European Union data protection requirements while supporting its continued operations in the region.
