Siemens Energy erected the 2.3 MW, 93-metre-tall turbines for German energy corporation E.ON over 122 days. The two companies are set to collaborate again on the London Array off the coast of the UK, the world’s first gigawatt-class offshore wind plant.

Rødsand II is among the world’s largest offshore wind farms and follows Rødsand I, a 72-turbine wind plant that began operating in a neighbouring location in 2003.

E.ON has invested about €400 million ($554 million) in this wind farm. This year two other E.ON offshore wind farms have become fully operational: Robin Rigg, which at 180 MW is one of the UK’s largest offshore wind farms, and Germany’s Alpha Ventus, the world’s first far shore, deep water wind farm.

“We now have gathered enough experience to master the further challenges in the German North and Baltic Seas. Offshore Wind is a strategic focus of E.ON’s renewable business,” said Frank Mastiaux, CEO of E.ON Climate & Renewables.

Jens-Peter Saul, CEO of the Siemens Wind Power Business Unit, described the project as “another important milestaone for us”.

“In the last 19 years we’ve put up 16 offshore wind parks totaling over 500 wind turbines, all of which are running reliably and successfully,” he said.

In the first stage of the London Array project, Siemens will supply 175 wind turbines of 3.6 MW each to the owners’ consortium, which includes E.ON, Denmark’s DONG Energy and Masdar Power, a renewable energy project developer based in Abu Dhabi.
