Ilmatar is preparing an approximately 45 MW wind farm in Loviisa, Uusimaa. The Tetom planning area is located east from Koskenkylä and is currently fully in forestry use.

The project is planned to comprise 8 wind turbine locations. Due to high-quality wind conditions the site is well suited for wind power production. In addition, the site is one of the only planned wind farm projects in Uusimaa’s coming regional master plan.

Project development and schedule

Tetom’s partial land use plan process was commenced in 2014. Ilmatar plans to deploy the latest turbine technology with expected tip heights up to 340m from sea level. The environmental impacts of the project will be investigated as part of the land use plan process.

The parallel use of the wind farm areas for example in recreational and berry picking purposes will be allowed also after the wind farm has been commissioned.

The construction schedule for the wind farm is open due to delays in the land use plan process. Ilmatar’s target is to start construction operations in early-2020s and the project to start generating power in 2024-2025.

Asset management

Ilmatar Service Oy, a subsidiary of Ilmatar Energy, will take over the wind farm’s technical and commercial management once the project has been commissioned.


Ilmatar is developing the project through its project company, Ilmatar Loviisa Oy, which is domiciled in Loviisa.

Current status

Tetom’s partial land use plan process is on-going. Drafting phase materials are available in:


In the next phase, a plan proposal will be submitted for public viewing.
