TikTok has unveiled plans to invest €1 billion ($1.16 billion) in a second data center in Finland, marking a significant step in its European infrastructure development. The announcement, made on April 7, highlights the company's continued effort to enhance data security and storage capabilities within the region.
The new data center will be located in the Kiveriö district of Lahti, a city northeast of Helsinki and west of Kouvola, where TikTok is already constructing its first Finnish data center. The first facility, announced nearly a year ago in April 2025, is being developed by Hyperco and is expected to offer an initial IT capacity of 100MW.
Christian Hannibal, TikTok’s head of public policy in Finland, emphasized the country’s appeal for such projects. "Finland offers a unique combination of strong digital infrastructure, access to clean and reliable energy, and a highly skilled workforce", he said. "That makes it a natural choice as we continue to expand our European infrastructure and strengthen how we protect and store data locally."
Both data centers in Finland are integral to TikTok's broader Project Clover initiative, a €12 billion ($13.8 billion) strategy aimed at bolstering European digital sovereignty. This project includes establishing multiple data center locations across Europe to address concerns about the security and localization of user data.
The company has previously opened facilities in other European countries, including a data center in Dublin, Ireland, which began operations in September 2023. While TikTok initially planned to expand its data center presence in Ireland, reports indicate that those plans have since been scaled back. In Norway, TikTok utilizes three data center buildings at Green Mountain’s OSL2-Hamar campus, all of which have been operational since April 2025.
Although TikTok has not disclosed the data center partner for the Lahti project, the Chinese data center company DayOne is known to be developing a 128MW campus in the same area. DayOne, which operates independently after rebranding from GDS International in January 2025, has also invested in Hyperco’s Kouvola data center project currently being used by TikTok. These developments further signal DayOne's growing footprint in the region.
The investment in European data centers is part of TikTok's ongoing response to global concerns about its ownership by ByteDance, a Chinese company. Governments in several countries have called for reassurance that user data is not being transferred to China. Project Clover aims to address these concerns by ensuring data storage remains within Europe.
TikTok’s investment in Finland reflects the growing importance of the country as a data center hub. While most of Finland’s data centers are concentrated around Helsinki, Lahti is emerging as an attractive alternative, with other companies like Polarnode and FCDC also developing facilities in the area.
As TikTok continues to expand its infrastructure across Europe, its commitment to data security and localization remains a central focus of its strategy. The second Finnish data center represents another step in solidifying its efforts under Project Clover.
