Helios: Tervamaki, Lisalmi

Lot Size: 247 acres

This site is being developed by Helios Nordic Energy Finland Oy as part of the company's expansion from solar and battery storage into data center land development. The project has moved through a submitted zoning initiative, with an environmental impact assessment now beginning alongside the municipal zoning review to evaluate the area's suitability for data center use. More than 100 hectares have been reserved for the campus, though no land purchase has taken place and no technical specifications have been disclosed. The site is planned to connect to a new regional grid substation, and local government has expressed support, describing it as a continuation of existing regional clean-energy development, though the project remains conditional on completing permitting.

Operating Company

Operated by:

Helios Nordic Energy Finland Oy is the Finnish subsidiary of Sweden's Helios Nordic Energy AB, founded in 2019 by Andreas Tunbjer, Magnus Rahm, and Johan Lundin. The Finnish entity was incorporated in January 2023, registered under Finnish business ID 3335744-4, and headquartered in Helsinki. Rather than operating facilities, Helios works as a land and project developer, managing site selection, permitting, and grid connection before handing projects to investors once they reach ready-to-build status. Since 2024, the company has been owned by SunMind, a subsidiary of VINCI Concessions, and remains led by group CEO Andreas Tunbjer. Helios has recently expanded from its core solar and battery-storage business into data center land development, including an early-stage project near Iisalmi, Finland.
