FRANKFURT, Dec 7 (Reuters) - German day-ahead power prices were boosted on Thursday by forecasts for falling wind power output from high levels this week but the contract proved to be the exception in a generally falling market.
* Traders said that demand was easing for next week while German wind generation, one of the most important swing factors in the region, is due to recover to healthy levels. France has meanwhile stabilised nuclear output after recent shortfalls had led to concern.
* German day-ahead baseload was 11.5 percent up at 34 euros ($40.04) per megawatt hour (MWh), while the equivalent French price was 9.4 off at 63 euros. The price premium over Germany reflects the generally tight nuclear situation.
* Electricity production from German wind turbines will likely fall 4.6 gigawatts (GW) in Germany to 22.4 GW on Friday but come in around 18-20 GW early next week, Thomson Reuters data showed.
* Given this picture, the currently high week-ahead price could not be sustained and dropped 7.8 percent to 41.5 euros.
* Supply concerns for the French market have been calmed with capacity of 83.6 percent of the installed total available for production. Three weeks ago, levels stood around 70 percent.
* French week 1 fell 3 percent to 64.2 euros.
* Year-ahead prices eased, shrugging off gains in the related coal and oil markets.
* Cal’18 French power shed 0.7 percent to 42.6 euros/MWh.
* The equivalent German contract was 0.8 percent down at 36.5 euros.
* Cif Europe coal for 2018 gained 0.2 percent to $85.9 a tonne and carbon for Dec 2017 expiry was level at 7.27 euros a tonne.
* In eastern Europe, the Czech price for the day-ahead was 5.75 euros up at 37 euros while year-ahead delivery was 10 cents down at 38 euros.
* BayernLB said in a market research note that impulses from coal and carbon were too weak to lift the German curve benchmark contract although demand indications for electricity next year remain strong in a buoyant economy.
* German utility Uniper told analysts and investors it plans to pay about 310 million euros in dividends for 2018, a year-on-year increase of about a quarter. Its Datteln 4 coal-fired plant is now due to come on stream in the fourth quarter of 2018. It had been expected to start in the first half.
