Finland – Siemens Gamesa has agreed to supply its leading 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 will install 69 SG 6.6-170 turbines at the site in Central Ostrobothnia in 2024. The wind turbines have a 170-meter rotor and a 6.6 MW generator, resulting in one of the industry’s lowest Levelized Cost of Energy (LCoE).
This is the second Finnish site to use the Siemens Gamesa 5.X, following an 81MW deal signed in early 2021 for the SG 6.6-155 variant. Lestijärvi will also be the country’s largest wind farm in terms of installed capacity, with an annual energy production of about 1.3 terawatt hours, equivalent to about 2% of Finland’s total electricity production.
The wind farm will also be covered by a 35-year full scope service agreement, ensuring that the turbines operate at full capacity throughout their lifespan. Sixty-four turbines will be installed on 155-meter towers, while the remaining five will be installed on 145-meter towers.
Indeed, according to the Finnish Wind Power Association, Finland plans to install 30 TWh of wind capacity by 2030, which would account for approximately 30% of the country’s electricity demand, up from approximately 7% at the end of 2019.
