The developer announced last week it would sell the project to a trio of Finnish companies but continue being responsible for its technical and commercial management under a 15-year agreement.
Construction is due to start imminently, with turbine installation scheduled for 2024 and commissioning expected in 2025.
A total of 64 turbines will sit on 155-meter towers, and the other five will use 145-meter towers.
The order, which includes a 35-year service agreement, is Siemens Gamesa’s second in Finland for the 5.X platform, following a deal for 14 SG 5.8-155 turbines for the 81MW Alajoki-Peuralinna site in central Finland signed late last year.
It is claimed the Lestijärvi project will be capable of achieving record-low levelised cost of energy (LCoE). Lestijärvi will be the largest wind farm in Finland by installed capacity and generate about 1.3TWh/year, representing roughly 2% of the country’s total electricity production.
According to the Finnish Wind Power Association, Finland aims to supply around 30% of its electricity demand from wind energy, up from around 7% in 2019.
