A solar farm developer is expanding into the data center sector, with plans to develop a campus in Finland. The municipality of Iisalmi this week announced that Swedish energy company Helios Nordic Energy is planning a new data center in the Tervamäki area. While full details have not been disclosed, the campus could span more than 100 hectares, and the company is currently progressing through the permitting process with the municipality.
“Finland's strengths for locating data centers include a safe and predictable operating environment, a reliable electricity grid, a cool climate, and high-quality telecommunications connections,” said Aleksi Aalto, project developer at Helios. “Finland has an excellent opportunity to become a leader in the industry. The need for data centers is now growing significantly, and in the current global situation, it is in the interest of all of us internet users that information about us can be processed securely on servers located in Finland.”
Iisalmi is a town and municipality in the North Savo region of central Finland. Fingrid Oyj’s transmission line runs to the west of the proposed site, with the data center expected to connect to Fingrid’s planned Tervamäki substation in the area.
"Tervamäki's large-scale data center planning project will open up a new, significant industry for the Iisalmi and Upper Savo region. If implemented, the project will bring significant investments to our region during the construction period and, most importantly, in the longer term, will create permanent jobs. Tervamäki is a natural continuation of the Vuorimäki and Rajamäki clean transition energy projects. The City of Iisalmi sees this as a desirable development for the future,” added Iisalmi Mayor Jarmo Ronkainen.
