VSB Finland has commissioned the 148 MW Karahka wind farm located in Oulainen, in the Northern Ostrobothnia region, Finland.
Owned by the Finnish utility company Helen and the Bank of Åland Wind Power Special Investment Fund, the 25 wind turbines are spread across an area of approximately 2,300 hectares. VSB Finland began developing the Karahka wind power project in 2016. In 2022, the project entered its construction phase when building permits were issued. In the same year, VSB sold Karahka to Helen and the Bank of Åland Wind Power Special Investment Fund, while remaining responsible for construction and commissioning. The Karahka wind farm is the second in a series of domestic renewable energy projects delivered by VSB to Helen and Ålandsbanken. Helen holds the majority ownership of the wind farm with a 51% stake.
For the wind farm, VSB, Nordex, and their partners adopted an innovative approach for the tower design, combining 27 concrete tower blocks topped with a steel section. This breakthrough enables taller hub heights, advancing wind power technology. The concrete components for these hybrid towers were produced locally by Lujabetoni in Kärsämäki.
