Korkia Pushes Over 2 GW of Data Center Sites Toward Grid Connection by 2029

Korkia's data center development portfolio now totals over 2 GW of planned capacity, with five key sites in Finland, the UK, Sweden and Chile and four targeting grid connection by the end of 2029, the company said in a news.cision.com announcement on November 11, 2026. Korkia is a Helsinki-based private investor that develops utility-scale solar, wind and battery storage projects with local partners.

Korkia's Five Sites and Their Grid Timelines

Korkia said the first sites can be connected to the grid as early as 2028. The company pairs the sites with renewable generation and battery storage, and in September 2026 it announced an expanded investment focus into powered land for data centers.

"Our powered land sites have moved quickly from strategy to scale," said Mikko Kantero, Executive Vice President, Portfolio Management & Growth at Korkia. "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."

The largest 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. Grid connection at the Walpole substation is expected in 2031 or earlier, and a public consultation by development partner Evolution Power is open until November 26, 2026.

In Sievi, Korkia and Semecon are developing a 250 MW site near Fingrid's Kukonkylä substation, with a connection date in late 2028 and potential to scale to 580 MW in 2029. A 15-hectare site in Ylivieska has a 70 MW connection expected in early 2029, and waste heat reuse is being studied with local energy company Herrfors. Sites in central Sweden and the Santiago region of Chile both target grid connection in late 2029.

Korkia's Development Scale

According to akta.pro company records, Korkia has over 160 renewable energy projects in active development and a 15 GW mature portfolio of solar, wind and BESS projects, with an additional 9 GW in early-phase development. The same records show the late-phase portfolio grew 101% in 2025, reaching approximately 15 GW by year-end, and that Korkia entered Chile in 2023 through a joint development company with Solar Ray.

Korkia's UK and Finnish Project History

In June 2026, Korkia achieved ready-to-build status for the 150 MWp Stonestreet Green Solar and 99.9 MW BESS project in Kent, UK, with partner Evolution Power, according to akta.pro company records. In September 2026, Evolution Power, a UK joint venture between Korkia and Evolution Power Holdings, secured a GBP-15-million development finance facility to support its solar and battery energy storage portfolio, Renewablesnow reported. Korkia also secured EUR 10.7 million in financing in September 2026, including a EUR 5 million loan from Nefco and a EUR 5.7 million bond issue, the company said at the time.

Korkia's Next Steps in the UK and Finland

Zoning and the environmental impact assessment for the Sievi data center are targeted for completion during 2027. The Longmarsh public consultation runs until November 26, 2026.
