In Frankfurt, the maximum temperature tomorrow is forecast at 5 degrees Celsius (41 Fahrenheit), in line with the five-year seasonal average, according to CustomWeather Inc. data on Bloomberg. Temperatures in Paris were forecast at 8 degrees Celsius, also in line with the average.
Wind output in Germany is predicted to rise to more than 20 gigawatts tomorrow, Meteologica SA, a Madrid-based weather forecaster, said on its website. Wind generation rose to a record 22.2 gigawatts on Jan. 3 of this year, data from European Energy Exchange AG showed.
German 2013 power has declined for the past four years, losing 17 percent this year to 44.05 euros, broker data show. That’s the lowest for a year-ahead contract since December 2009.
