Clean power supplied almost all of Germany’s power demand for the first time on Sunday, marking a milestone for Chancellor Angela Merkel’s “Energiewende” policy to boost renewables while phasing out nuclear and fossil fuels.
Solar and wind power peaked at 2 p.m. local time on Sunday, allowing renewables to supply 45.5 gigawatts as demand was 45.8 gigawatts, according to provisional data by Agora Energiewende, a research institute in Berlin. Power prices turned negative during several 15-minute periods yesterday, dropping as low as minus 50 euros ($57) a megawatt-hour, according to data from Epex Spot.
Countries around Europe are building increasing amounts of renewable capacity in order to reduce their carbon emissions and boost supply security. Last year Denmark’s wind farms supplied 140 percent of demand, while the U.K. had no coal-fired power stations meeting electricity demand for about four hours on May 10 as a result of plant breakdowns.
“Events like this highlight that eventually we may need to start curtailing because of market-wide oversupply,” said Monne Depraetere, an analyst for Bloomberg New Energy Finance. “In the long-run, that may provide a case to build technologies that can manage this oversupply -- for example more interconnectors or energy storage.”
