TikTok Investing $1.16 Billion for Second Data Center in Finland

TikTok has announced that it will invest €1 billion, or $1.16 billion, to build its second data center in Finland. The new facility will be located in Lahti, a city in southern Finland, and will initially operate with a 50-megawatt capacity.

The Lahti site is designed to scale up to 128 megawatts as service demand increases. The facility is currently expected to begin operations next year.

This development follows TikTok’s first Finnish data center project in Kouvola. That initial facility is scheduled to begin energy operations by the end of this year.

The investment is part of TikTok’s €12 billion European data sovereignty initiative. This strategy aims to keep the data of its 200 million European users protected within the region.

TikTok currently stores European user data in facilities located in the United States, Ireland, and Norway. The new Finnish centers will help shift more of this information exclusively to European soil.

Storing data locally helps the company respond to increasing scrutiny from Western regulators over data privacy and security. TikTok is owned by the Chinese technology company ByteDance.

Earlier this year, the company restructured its operations in the United States, giving the American technology firm Oracle a majority stake to avoid a national ban.

Finland’s growing reputation as a data hub

Finland has become a highly attractive destination for international tech companies building digital infrastructure. The country offers a stable regulatory environment and access to lower-cost renewable energy resources.

Finland’s electricity generation is heavily focused on green and low-carbon sources. The national energy mix is led by nuclear power, followed by wind and hydropower.

The country successfully closed its last coal-fired power plant in 2025. This transition allows tech companies to operate energy-intensive infrastructure while meeting their internal climate goals.

Finland operates five nuclear reactors, including the 1,600-megawatt Olkiluoto 3, which is among the most powerful reactors in the world. Energy companies like Fortum are actively modernizing turbines at other plants to maintain a reliable power grid for industrial use.

Despite the benefits, the rapid growth of the data center industry has sparked some environmental and cost concerns. Critics note that the massive electricity demand from these facilities could potentially drive consumer energy prices higher.

To manage these challenges, Finland is prioritizing grid stability and testing innovative systems, including artificial intelligence pilots designed to balance energy distribution. Tech companies are also integrating into the local energy network to offset their footprint.

For example, Google is expanding a heat recovery system at its Hamina data center to provide district heating for the surrounding community. These cooperative models are becoming standard practice for foreign companies looking to operate sustainably in the Finnish market.
