Nordic data center firm atNorth is looking to expand one of its campuses in Finland.

Yle reports the company has applied for a building permit for three new data center buildings in Kouvola. The local council is set to discuss the request this week.

The data centers would be located in Ummeljoki/Myllykoski, expanding its in-development FIN04 campus.

Kouvola is the administrative capital of Kymenlaakso, located some 135km (83.8 miles) northeast of Helsinki.

Plans for FIN04 were first announced in late 2023. At the time, the company said the 23-hectare site would open with 60MW with potential to reach "several hundred megawatts" when fully built. The company now lists the site as offering up to 430MW of capacity across 45 hectares, with a path to “several hundred additional megawatts.”

Yle said ground was broken on the first building in 2024 and is due to go live in the first half of 2027. AtNorth’s website said the site will be ready for operation in the first half of 2026.

The FIN04 site will be connected to the local district heating scheme, run by local energy company, KSS Energia.

Nordic operator atNorth currently operates seven data centers across Sweden, Iceland, and Finland, with more in development in Finland, Denmark, Sweden, and Norway.

The company previously acquired two Finnish data centers, FIN01 and FIN03 in Vallila and Espoo, respectively, from its former parent Advania, and has also announced the construction of a third 15MW facility in Espoo.

AtNorth was formed as Advania Data Centers in 2012 from three components: Skyrr, a public sector IT specialist in Iceland; Kerfi, a Swedish outfit with roots in a Nokia spin-off called Datapoint, and Hands from Norway. The company de-merged from the Advania Group in 2017 and rebranded to atNorth in 2020. Swiss investment manager Partners Group acquired the company in December 2021.

US colo giants Digital Realty and Equinix are reportedly competing to acquire atNorth, according to a recent report.
