German Offshore Wind Power Link for 1 Million Homes Gets Going

Siemens AG and TenneT Holding BV completed an 800-megawatt power-transmission project that will link two North Sea wind farms to Germany’s land-based electrical grid.

BorWin2 combines an offshore platform and 200 kilometer (125 mile) direct-current cable that can transmit enough power for about 1 million homes, grid operator TenneT said today in an e-mailed statement. The Global Tech 1 and Veja Mate wind farms will be hooked to BorWin2, it said.

“This is the first offshore grid connection worldwide to take up commercial operation with efficient direct-current technology,” Jan Mrosik, head of Siemens’ energy management division, said in a separate statement. Siemens built the project with Italian cable company Prysmian SpA.

Germany is banking on offshore wind farms to cut fossil fuel use and help replace nuclear power generation capacity that has been lost as it shutters its atomic reactors by 2022. Germany is set to become the biggest market for offshore wind installations this year, for the first time overtaking the U.K.

TenneT, which invested in BorWin2 with Mitsubishi Corp., said it sees grid connections with a total capacity of at least 7.1 gigawatts by 2019 in the North Sea. The Sylwin1, HelWin1 and HelWin2 links will start operating in the first half, Siemens said.
