Siemens Gamesa has signed a 455 MW deal with Swedish developer OX2 to supply its Siemens Gamesa 5.X platform to the Lestijärvi site for what will be Finland’s largest ever wind farm, assisting the country in making a giant leap in its energy transition. The wind project would be using 69 SG 6.6-170 turbines, which will be installed in Central Ostrobothnia in 2024. The wind turbines have a 170-meter rotor and a 6.6 MW generator.
As per the reports, following an 81 MW agreement for the SG 6.6-155 variant in early 2021, this is the second Finnish site to employ the Siemens Gamesa 5.X. Lestijärvi will also be the country’s largest wind farm in terms of installed capacity, with annual energy production of roughly 1.3 terawatt hours, or around 2 per cent of Finland’s total electricity production, when completed. A 35-year full scope service agreement will also be in place for the wind farm, ensuring that the turbines run at their greatest capacity throughout their lifespan. A total of 64 turbines will be on 155-meter towers, while the remaining 5 will be on 145-meter towers.
Finland expects to add 30 TWh of wind capacity by 2030, accounting for almost 30 per cent of the country’s electricity demand, up from around 7 per cent at the end of 2019. In August 2021, Taaleri Energia placed a 126 MW order with Vestas for the Isoneva project in Finland, bringing the total number of solid orders for the EnVentus platform in Finland to over 1.8 GW. The wind farm is located in the municipality of Siikajoki in northwestern Finland.
