Tahkoluoto offshore wind farm extension


Suomen Hyötytuuli Oy is planning to extend Tahkoluoto wind farm in Pori.
The planned area is located at sea, approximately 4 kilometres from the Tahkoluoto port area and 30 kilometres northwest of the Pori city centre. On the north side, the area is bordered by the municipal boundary of Merikarvia. The total area is approximately 135 square kilometres.

The wind farm envisaged for the planned area will consist of up to 45 offshore wind turbines with a maximum height of about 310 metres and a unit capacity of about 11–20 MW. The project contributes to Finland’s climate objectives, and if implemented, it will produce approximately 1,000–1,900 GWh of carbon-neutral electricity annually.
The environmental impact of the project is currently being assessed.

Approval process

The official EIA website for the project, where you can find the EIA report and instructions for submitting a statement or opinion, is available on the website of Finland’s environmental administration at ymparisto.fi/porimerituulipuistoYVA.

The component master plan is currently being prepared. The land use documents can be found on the City of Pori’s website at https://www.pori.fi/merituulipuisto


In accordance with the project plan presented in the EIA report, illustrative videos were created at Aboa Mare using the Wärtsilä Voyage (formerly Transas) ship handling simulator. The videos are available at:
