Siemens in Cape Wind turbine deal

Siemens has signed a deal to supply turbines to Cape Wind, in a boost to the project team seeking to build the first US offshore wind farm.

The German group will supply its 3.6MW turbines, a transformer platform and 15 years-worth of service to the wind farm in Nantucket Sound south of Cape Cod, Massachusetts.

Siemens is not currently releasing the number of turbines involved in the agreement, said a spokeswoman for the company in the US.

Cape Wind has a nameplate capacity of 468MW, representing 130 of the turbines, and has so far secured power purchase agreements equivalent to 77.5% of its output.

Siemens was first linked with Cape Wind in early 2010. The manufacturer has previously said it expects an proportionate number of turbines – amounting to 101 – to make up the first tranche of the project.

Siemens said it will base its O&M activities  for Cape Wind at Falmouth Harbor Cape Cod, and will subcontract construction of the offshore platform to Cianbro, which will carry out production at its facility in Brewer, Maine.

The turbine deal comes soon after Siemens officials reportedly said Cape Wind had moved sufficiently far forward with construction to qualify for US federal tax credits. The German giant has also indicated it may help finance the project, which still faces legal challenges from opponents.

"This is a significant milestone for this project and we're excited about it," said Massachusetts Governor Deval Patrick. "Massachusetts will be a pioneer in the emerging offshore wind industry, which brings with it both clean energy and good jobs."

Jim Gordon, president of Cape Wind said: "The completion and execution of the contracts between Cape Wind and Siemens brings the experience and financial strength of the leading global offshore wind supplier into America's first offshore wind farm ensuring important energy, environmental and economic benefits for Massachusetts and the region."
