FRANKFURT, Oct 21 (Reuters) - European prompt prices on Tuesday were lifted by expectations for a sharp a decline in German wind power generation, which will make the country an importer on the day-ahead. "The signal is bullish for Germany. Wind supply is deceasing significantly," said LSEG analyst Xiulan He, also listing rising German demand. French baseload for the day ahead was at 69 euros ($80.47) per megawatt hour (MWh) at 0740 GMT, up 39.4%, LSEG data showed. German day-ahead was indicated in a 119-124 euros/MWh bid-ask range, having closed at 63.3 euros. LSEG data showed Germany wind power output at 17.6 gigawatts (GW) on Wednesday, more than half down from a projected 36.5 GW on Tuesday, and France's wind output will likely lose 4.1 GW to hit 5.7 GW. Countering the impact of supply shortfalls was overnight routine data from French nuclear operator EDF, showing that reactor availability has gained 7 percentage points compared with Monday, standing at 79% of installed capacity. Power demand signals were also mixed in the two main markets. Germany was due to see an increase by 600 MW day-on-day to 58.3 GW, led by falling temperatures, and France was set for a decline by 400 MW to 46.5 GW, as local temperatures ticked higher. German year-ahead baseload was 1% lower at 87.1 euros/MWh and its French equivalent contract was quoted flat, but untraded, after closing at 56.5 euros/MWh. EU energy ministers on Monday backed a proposal to phase out Russian oil and gas imports to the bloc by January 2028. German retail consumer portal Verivox said that a 6.5 billion euros state subsidy to lower electricity grid costs will likely cut end-consumer prices by 6% from January onwards, compared with October. They should reach 32.33 cents/kilowatt hour on average. The grid costs, a price element worth more than a quarter of household bills, had risen 47% between 2020 and 2025.
