Korsnäs Offshore Wind Farm

Metsähallitus' Climate Programme promotes the attainment of Finland's climate targets and transition to a carbon-neutral society by 2035 through increasing carbon sinks, carbon storage and clean energy production as well as by cutting emissions. In line with this, we are developing an offshore wind farm, 15 km off the coast of Korsnäs municipality, on the west coast of Finland.

In this project, Metsähallitus operates both as a project developer for wind power and as an issuer and lessor of reservation and access rights contracts. We are looking for a partner whose expertise is in building and operating the wind power business once the project is completed in the late 2020s. The partner must meet our responsibility criteria.

The planned nominal capacity of the Korsnäs offshore wind farm is at least 1,300 megawatts. If the offshore wind farm were completed now, it would increase Finland’s wind power production by almost a fifth.


In 2021, nature surveys were launched in the planned area of the Korsnäs offshore wind farm. The surveys will be continued in 2022.
Other preliminary studies related to environmental impact assessment (EIA) are also underway.
Wind measurements and local stakeholder events will begin towards the end of year 2021.

Korsnäs offshore wind farm: Facts and figures

During the first phase of the project, 70 to 100 turbines with a nominal power of 12 to 20 megawatts would be built in the area.
The annual production of the wind farm is estimated at about 5,000 GWh. For instance, it would be enough to meet the electricity needs of 250,000 detached houses throughout the year, including electric heating.

Next steps in Korsnäs offshore wind farm project

Wind power projects are progressing through several stages.
As the project progresses, its effects on the local community and natural values are assessed, permits are applied for, and zoning issues are clarified. At the same time, the technical design and implementation of the project is progressing.

Metsähallitus’ operating model for offshore wind power

Korsnäs is the first offshore wind power project where Metsähallitus acts as a project developer.
As this is a large-scale project, we will organize a tender competition to find a responsible partner for the project. Partners are sought domestic and abroad.

Offshore wind power and Finland's climate goals

Finland’s goal is to be a fossil-free welfare society by 2035 through increasing carbon sinks, carbon storage and clean energy production as well as by cutting our emissions.
Our goal is to triple wind power production in our areas by 2030.

Great potential in offshore wind

The construction and operation of an offshore wind farm has significant positive effects on the regional economy and business activities.
As soon as the wind farm is in operation, the energy company responsible for its business will pay the municipality a significant property tax.
