German Day-Ahead Power Drops on High Wind Output, Warmer Weather

German electricity for next-day delivery fell as forecasts for more wind generation indicated higher supplies.

Baseload German power for the next working day, for delivery around the clock, slid as much as 27 percent to 32.25 euros ($43.42) a megawatt-hour and last traded at 32.50 euros at 6:09 p.m. Berlin-time, according to broker data compiled by Bloomberg.

Wind generation tomorrow will rise to more than 20,000 megawatts compared with a low of around 7,000 megawatts today, Meteologica SA, a Madrid-based weather forecaster, said on its website.

German power line operators warned today that high wind output tomorrow may put the grid’s stability at risk and have asked for idled reserve plants to start up to keep the balance, German grid operator Tennet TSO GmbH said today in an e-mailed statement.

German February power gained for the first time in four days. The contract rose as much as 2.6 percent to 44.65 euros a megawatt-hour, after dropping to a four-week low of 43.30 euros on Jan. 25. French power for February advanced as much as 4.3 percent to 51.75 euros, the biggest daily increase since Bloomberg started tracing the record Nov. 2012. The contract had slid to a record 49.50 euros on Jan. 25.

In France, nuclear power generation is set to increase to 59,851 megawatts on Feb. 1 from 58,183 megawatts tomorrow, according to data from the country’s grid operator Reseau de Transport d’Electricite. The 1,335-megawatt nuclear reactor St. Alban-2 will resume output Jan. 30 after an unplanned halt yesterday due to a boiler fault, RTE said.
