EUROPE POWER-Spot prices fall in subdued pre-holiday trade

FRANKFURT, May 25 (Reuters) - European prompt power prices for the coming days fell on plenty of wind power and weakening demand on Wednesday ahead of a holiday on Thursday, which ushered in lower industrial and business activity in the rest of the week.

Germany's Friday baseload, on a bridging day after May 26's Ascension Day, traded at 66 euros ($70.44) per megawatt hour (MWh) at 0850 GMT, down 64% from Wednesday delivery.

The equivalent French price was bid down 13% from Wednesday delivery at 162 euros, but untraded.

Supply from German wind turbines was due to rise to 29.6 and 38.8 gigawatt (GW) on Thursday and Friday, respectively, from 13 GW predicted for Wednesday, Refinitiv Eikon data showed.

Daily German wind volumes should be down at between 5 and 13 GW next week, the data showed, which pushed up the week-ahead baseload price up by 2.7% to 192 euros.

French nuclear power availability remained at 50% of installed capacity.

Power demand in Germany was seen at 52.5 GW on Friday after 58.2 GW Wednesday, and in France was pegged at 40.7 GW that day, down from 44.9 GW.

Along the curve, German front-year baseload added 2% at 228 euros, tracking firmer carbon and oil.

Its French counterpart was untraded after closing at 303 euros.

European CO2 allowances for December 2022 expiry increased by 0.2% to 81.47 euros a tonne after a weaker start.

Gas supply has been stable of late and milder weather has curbed demand but concerns that Russia could disrupt or halt flows have a knock-on effect on the wider power sector.

Gazprom said on Wednesday its supply of gas to Europe through Ukraine via the Sudzha entry point was down. Flows to Germany via Poland were also lower.
