Korkia advances over 2 GW of data center sites across its development portfolio

Data center sites in Korkia’s development portfolio now total over 2 GW of planned data center capacity. Five key sites in the UK, Finland, Sweden and Chile are developed alongside renewable generation and battery storage, and four of them are targeting grid connection by the end of 2029.

Access to power has become one of the defining constraints for new industry and energy infrastructure investments. Grid capacity is limited in many markets, and sites with secured land, permits and a clear route to the grid are in short supply. In September 2026, Korkia announced its expanded investment focus into powered land for data centers. Many of these sites are developed together with renewable generation and battery storage projects in Korkia’s existing portfolio, offering data center operators a clear and near-term route to power.

“Our powered land sites have moved quickly from strategy to scale. We currently have over 2 GW of data center capacity across four markets, and the first sites can be connected to the grid as early as 2028. These sites bring together a defined route to grid power with renewable generation and storage on site, so we can offer data center developers access to power on a timeline that few sites in these markets can match. That is where we see the value,” says Mikko Kantero, Executive Vice President, Portfolio Management & Growth at Korkia.

Advanced key sites in the UK and Finland

Longmarsh, United Kingdom

Korkia’s largest powered land site, Longmarsh in Norfolk, combines up to 1 GW of data center capacity with 1.3 GWp of solar and battery storage on about 1,900 hectares. The project is planned across two sites, with the data center campus located next to solar generation and battery storage so that it can draw power directly from the solar farm. Grid connection at the Walpole substation is expected in 2031 or earlier. A public consultation by Korkia’s development partner Evolution Power is open until 26 November 2026.

“It’s exciting to see our UK powered land sites moving forward. Longmarsh project shows how much potential there is in combining new electricity demand with generation and storage,” says Peter Bolton, Vice President, Portfolio Investments at Korkia.

Malakakangas, Finland

In Sievi, Korkia and Semecon are developing a data center site near to Fingrid’s Kukonkylä substation. The planned capacity for the site is 250 MW, with connection date in late 2028, and there is potential to scale up to 580 MW in 2029 as a higher-voltage connection becomes available. The site sits next to the Malakakangas hybrid generation park, where the 77 MW wind farm and 125 MW battery storage are already ready-to-build, and permitting for a 70 MW solar park is underway. Zoning and the environmental impact assessment for the data center are targeted for completion during 2027, with strong support from the municipality.

Ylivieska, Finland

In Ylivieska, a 15-hectare site has been reserved for a data center. The site is located in an area already zoned for industrial use, which supports a faster route to permitting. A 70 MW connection on the existing connection line is expected to be available in early 2029. The possibility to reuse the data center’s waste heat is also being studied in cooperation with the local energy company Herrfors.

“Northern Ostrobothnia combines a growing base of renewable generation with access to the transmission grid, which makes it a natural location for new large electricity users. In Sievi and Ylivieska, we work with Semecon and the municipalities to develop sites that bring new demand close to generation, and open dialogue with residents and local businesses is an essential part of that work,” says Matti Manner, Vice President, Nordics at Korkia.

Further opportunities in Sweden and Chile

Sweden

In Sweden, Korkia is advancing powered land opportunities that build on its development team in Sweden and its portfolio of solar and battery storage projects. One of these is a data center site in central Sweden, a region with an established data center presence. Grid connection for the site is targeted for late 2029. With an established data center market, Sweden is a natural market for combining new electricity demand with generation and storage.

Chile

In Chile, Korkia is advancing powered land opportunities that build on its established renewables platform and local development partnerships. One of these is a data center site in the Santiago region, which is emerging as one of South America’s leading data center hubs. The site has the potential to connect to the grid in late 2029. Chile’s strong renewable resources and growing data center demand make it a natural market for combining new electricity demand with generation and storage. The country’s National Data Center Plan aims to triple national capacity by 2030, and recent regulatory changes allow faster approvals for data centers.

Building the infrastructure the energy transition needs

As electrification accelerates, the power system needs a combination of renewable generation, energy storage, grid capacity and well-planned locations for large new electricity users. Rather than focusing on a single technology, Korkia looks at the power system as a whole. It invests in the pieces the system needs, where it needs them, and helps solve the bottlenecks that slow the transition down.

“The world is electrifying fast, and the power system needs infrastructure to keep up. We invest in the pieces the system needs and help solve its bottlenecks. Powered land is a natural extension of that work: by bringing new electricity demand together with renewable generation, battery storage and grid infrastructure, we help build a stronger, more flexible grid while creating long-term value for our investors and customers,” says Mikko Kantero.

Powered land is one part of this approach, alongside Korkia’s solar, wind and battery storage assets. Every site is developed with long-term value in mind: for investors, for local communities and for a stronger, more resilient power system.
