The wind project will deploy 69 of the SG 6.6-170 turbines to be installed in 2024 at the site in Central Ostrobothnia. The wind turbines are equipped with a 170-metre rotor and 6.6 MW generator providing one of the lowest Levelised Cost of Energy (LCoE) in the industry.
This is the second Finnish site that will use the Siemens Gamesa 5.X following an 81 MW deal signed for the SG 6.6-155 variant in early 2021. Lestijärvi will also be the largest ever wind farm in the country by installed capacity and when completed its annual energy production will be about 1.3 terawatt hours, equivalent to around two percent of Finland's total electricity production.
The wind farm will also be covered by a 35-year full scope service agreement assuring the turbines operate at their maximum capacity over their lifetime. A total of 64 turbines will sit on 155-metre towers, and the other five will use 145-metre towers.
“This contract marks an important step for the Siemens Gamesa 5.X platform in Finland” said Lars Bondo Krogsgaard, CEO of Siemens Gamesa’s Onshore business unit. “Working with long-standing partner OX2 we are helping the country to take giant strides in its energy transition by providing one of the lowest LCoE across the industry. The Nordics are again showing strong appetite to use leading technology to provide competitive green energy.”
Indeed, according to the Finnish Wind Power Association, Finland plans to install 30 TWh of wind capacity by 2030, which would provide around 30 percent of the country’s electricity demand, up from around 7 percent at the end of 2019.
