About the project

Niinimäki wind farm is located in the town of Pieksämäki, Finland.

The wind farm consists of 22 wind turbines with a total capacity of 145.2 MW. The total height of the turbines is 250 metres. The estimated annual production of the wind farm is over 400 GWh, which is equivalent to the annual electricity consumption of about 80,000 households (5,000 kWh/household).

The construction of the Niinimäki wind farm started in winter 2022. The wind farm was handed over to its owners Helen and Ålandsbanken Tuulivoima Erikoissijoitusrahasto in September 2025. OX2 is responsible for the technical and commercial management of the wind farm.
