Siemens has been awarded its first commercial offshore wind order from Finland: the company will supply, install and commission 10 wind turbines, each with a capacity of 4 MW and a rotor diameter of 130 m, for the Tahkoluoto offshore wind farm in the Baltic Sea.

With a capacity of 40 MW, the first Finnish offshore wind power plant is expected to have an annual net power production of over 155 GWh. Installation of the wind turbines is scheduled to begin in the summer of 2017, with the start of operations expected by autumn 2017. Siemens will not only deliver the turbines, but will also be responsible for the service. The customer is Suomen Hyötytuuli Oy, a wind power producer owned by eight Finnish utilities, headquartered in Pori.

"This order marks a significant milestone for Siemens. The project is not only the first offshore wind farm in Finland, but will also be used by the Finnish government to demonstrate that offshore wind power is a feasible solution for this area," said Michael Hannibal, CEO Offshore of the Siemens Wind Power and Renewables Division.”

Tahkoluoto offshore wind farm is located approx. 0.5 to 3 km from shore in water depths from 8 to 15 m. The wind turbines will be mounted on specially designed, gravity-based steel foundations in order to withstand heavy ice loading. The government of Finland is also contributing € 20 million toward the demonstration project in icing conditions.

“The conditions for offshore wind power are excellent in Finland. We have a long coastline, windy conditions, shallow waters, and a hard seafloor,” says Toni Sulameri, the Managing Director of Suomen Hyötytuuli Oy. In 2010, Siemens already supplied one wind turbine with a capacity of 2.3 MW to Suomen Hyötytuuli Oy for the Pori pilot project, located 1.2 km off the Finnish coast. This pilot turbine will be surrounded by the 10 wind turbines of the Tahkoluoto wind farm.
