Wind turbines manufacturer Senvion has concluded the turbine delivery and service contract for the 203MW Trianel Borkum II (TWBII) wind farm project in the German North Sea.

In September 2016, Senvion has entered into a conditional contract for the offshore wind farm, which will be installed 45 kilometers north of the island Borkum.

Last April, a group of 20 shareholders from Germany and Switzerland have given their consent to build the €800m Trianel Borkum II wind farm.

Planned to be installed at a water depth between 25m and 35m, the offshore wind farm will include 32 Senvion 326.2M152 turbines with a power upgrade.

The facility will hold capacity to generate around 800 million kilowatt-hours of electricity per annum, which can power about 210,000 households annually.

The installation of the turbine components is expected to begin in spring 2019 at the project, which is near to the alpha ventus wind farm that features six 5M 126 Senvion offshore turbines.

Senvion CEO Jürgen Geissinger said: "We are very pleased with the completion of this contract and the confidence the Trianel project-consortium has shown in our turbines.

“We look forward to a successful partnership together. It is particularly significant that Senvion has been awarded one of the last offshore projects under the current German feed-in tariff regime.”

TWB II commercial director Klaus Horstick said: “From spring 2018 onwards the Trianel Windpark Borkum II will be installed in the North Sea and will expand the municipal offshore engagement."

The stakeholders in the Trianel offshore wind farm II include EWE holding 37.5% and a joint venture of the electricity utility of the city of Zurich and the Swiss company Fontavis holding 24.51%. A 37.99% stake is held by 17 Stadtwerken from Germany and the Stadtwerk-Cooperation Trianel.
