Chancellor Angela Merkel’s renewable power strategy has received a considerable boost after Germany’s power transmission companies put forward plans to build four electricity Autobahns to link wind turbines off the north coast with manufacturing centres in the south of the country, at a cost of $24bn.

Tennet, Amprion, 50 Hertz and Transnet BW intend to strum up support for their plans to build 3800km high-voltage electricity lines over the next ten years.

In a first blueprint for the government, the companies proposed 2,100km of direct-current power lines – similar to those used for undersea links like that between the UK to the European continent – to connect the North Sea and the Baltic coasts to the south.

The stability of the electricity network has proved a serious headache for Frau Merkel as it was designed to pipe nuclear electricity from south to north, not renewable electricity from the coast.
