GreenScale has announced plans for a large data center development in southern Norway.

The company this week announced the acquisition of Tonstad DataPark, a new data center development located in the municipality of Sirdal in West Agder County (NO2), Norway. Terms of the deal were not shared.

Tonstad DataPark spans a 420,000 square meter (4.5 million sq ft) site with 300MW of grid capacity, approved by Glitre Nett and Statnett. GreenScale aims to invest more than €2.5 billion ($2.85bn) developing a four-building campus, with the first phase of capacity targeted for 2027.

GreenScale claimed the site will be the largest data center development of its kind in Norway.

“This latest chapter in our short but remarkable story is a big step forward for us and the viability of using alternative or renewable energy sources for Hyperscale and AI-ready data centers as a whole, while bringing a new 300MVA campus to the market in a very well developed region for customers in Europe” said Dan Thomas, GreenScale CEO.

“With every facet of this facility oriented towards supporting customer requirements for network, compute, and high-density workloads, it was crucial for us to develop in a region with high levels of energy stability, alternative and renewable sources of power, and at the same time ensure a sustainable economic development.”

Investment firm Digital Transformation Capital Partners (DTCP) launched GreenScale last year with plans to develop 1GW of capacity.

The company was seeded with DTCP’s Atlantic Hub unit, which is developing two campuses in Northern Ireland and the Republic of Ireland. At the time, DTCP said GreenScale was also targeting 300MW of developments in the Nordics, but didn’t share details.

“After five years in development, we are delighted that GreenScale is realizing the exciting vision for Tonstad DataPark,” said Tore Knapskog, CEO of Tonstad DataPark. “We chose to work with DTCP and GreenScale as they gave us complete confidence in being able to deliver – from securing the power, the land, and ultimately building a sustainable data center campus. The last 12 months have been a truly collaborative partnership – one built on trust and ability.”

DTCP is an investment management firm with $3 billion in assets under management; DTCP Infra specializes in European digital infrastructure investments, including mobile towers, fiber networks, and data centers. The firm’s infrastructure investments include fiber companies Community Fibre, Cellnex Netherlands, Open Dutch Fiber, and German data center firm Maincubes.

DTCP was spun out of Deutsche Telekom in 2015 but retains close ties to the telco. Last month, Deutsche Telekom said the company was planning to add five new hubs to its existing estate of 16 data centers through an initiative known as Project Xcalibur, which is the name GreenScale had been operating under prior to officially launching.
