The German government is set to ignore calls for more offshore wind blocs, as the country’s grid is not sufficiently developedOffshore wind energy turbine installation to take in the extra energy.

The country’s first offshore auction finished last month with the winners willing to go without subsidies for the first time.

“You can forget lifting the caps before the election in September,” the Social Democrat’s spokesman for energy, Bernd Westphal, said in an interview at a wind conference in the port of Bremerhaven. “With power grid expansion delays, this just won’t make sense.”

Speaking at the same event, Felix Wuertenberger, head of Vattenfall’s offshore development in Germany and the Netherlands, on Wednesday urged the government to raise auction limits beyond the planned 3 gigawatts in 2017 and 2018 to bring down technology costs.

Developers of North Sea wind projects need to build at least 4 gigawatts of capacity a year from 2020 — equal to one turbine a day — to keep the industry buoyant, said Siemens Gamesa Renewable Energy’s new Chief Executive Officer Markus Tacke at the event.

Some 7 gigawatts a year would be more appropriate to “generate sufficient volume to lower costs and sustain innovation,” said Tacke. Just 1 percent of the sea’s wind power potential is currently under development, according to the company.

Germany’s plan to build three high-voltage power lines to transmit wind and solar power from the north to the south of the country won’t be realized before 2025 and at the moment the country is struggling to incorporate the levels of green energy already coming into the system.
