Ilmatar Commissions 186 MW Pahkakoski Wind Farm

Ilmatar has officially started commercial operations at its Pahkakoski Wind Farm in Ii, Northern Ostrobothnia, which comprises 30 turbines with a combined capacity of 186 MW. The Pahkakoski wind farm is estimated to produce a total of 600 gigawatt-hours (GWh) of clean, emission-free renewable energy annually. This corresponds to the electricity needs of up to 240,000 apartments or more than 30,000 detached houses.

Construction began at the end of 2023. To optimize progress, Ilmatar applied the so-called TCI contracting model (Transport, Crane and Installation), where special transports, lifting, and installation work are not included in the turbine supplier’s delivery, as is typical. Pahkakoski is one of the first large-scale projects in Europe built using this model. The turbines at Pahkakoski are among the tallest in Finland, with a tip height of 245 meters. The park is one of the largest single wind farms ever built in Finland.

The 30-turbine Pahkakoski wind farm is Ilmatar’s second-largest project. The largest, a 36-turbine park in Alajärvi, South Ostrobothnia, was commissioned in December 2023. Ilmatar now operates 109 turbines commercially. Currently, Ilmatar has ten wind farms and one solar farm in commercial operation. In total, Ilmatar has more than one gigawatt of renewable production in operation and is fully investment-ready.
