Project description

Solarigo is developing a large-scale hybrid park in Toholampi, Finland, combining utility-scale solar power generation with battery energy storage (BESS). With a planned total capacity of approximately 250 MW, the project is the largest in Solarigo’s history and marks the company’s first project to advance into the zoning phase.

The hybrid park is planned primarily on agricultural land, with part of the project area located on former peat production sites. By combining renewable energy generation with battery storage, the project is designed to support both clean electricity production and greater flexibility in the power system.

The project’s grid connection is expected to be enabled by a planned substation in Ullava, strengthening the region’s energy infrastructure and facilitating the integration of renewable energy into Finland’s transmission network.

Once completed, the Toholampi Hybrid Park is expected to become one of Finland’s most significant solar power and energy storage projects.

Zoning process initiated

Solarigo has submitted a zoning initiative for the development of the Toholampi Hybrid Park. During the zoning process, a public information event will be organized, and the project will be developed in close cooperation with local stakeholders. The project’s impacts will be assessed in greater detail as the planning process progresses.

Q1/2025

Preliminary assessments

Extensive preliminary studies have been carried out as part of the project development process, with particular emphasis on environmental and biodiversity assessments. Based on the current plans, no need for an Environmental Impact Assessment (EIA) procedure has been identified for the project.
