(Recasts to describe curve losses tracking CO2, RWE news)
FRANKFURT, Oct 9 (Reuters) - European forward power prices fell on the wholesale market on Tuesday afternoon as carbon emissions prices, which have a big influence especially on Germany’s electricity sector, slid.
* German baseload Cal’19, the European benchmark, was 2.6 percent off from its previous close at 54.2 euros ($62.24) a megawatt hour (MWh), a one-week low and down from an earlier session high of 55.9 euros.
* European December 2018 expiry CO2 allowances, which power generators must hold to cover their output, shed 4.3 percent to 21 euros a tonne.
* German power generation relies on hard and brown coal for just under 40 percent of total output.
* French baseload power for 2019 delivery was down 2.5 percent at 59 euros/MWh. While France relies mainly on nuclear energy that is virtually CO2 free, its market interacts with Germany’s due to smooth interconnection.
* European delivery API2 coal for 2019, another big generation cost, was 1.8 percent down at $97 a tonne.
* Spot power prices fell on more wind power supply and with demand easing in a brief early-autumn temperature surge expected to end next week.
* The German baseload power price for the day-ahead , at 63.75 euros/MWh, was 5.9 percent down.
* The equivalent French price was 6.3 percent off at 67.5 euros/MWh.
* German wind power generation will likely rise by 1.9 gigawatts (GW) to 7 GW on Wednesday, and then reach 15 GW on Thursday, Refinitiv Eikon data showed.
* French nuclear supply remains at 73.1 percent of maximum capacity.
* Electricity demand will likely fall 0.8 GW day-on-day in Germany and 1 GW in France. Next week showed predicted average falls to daily demand levels of around 61.5 GW and 48.3 GW, down 4.5 GW and 2.1 GW respectively from those recorded on Tuesday in the two countries.
* German utility RWE expects to reduce output of lignite, also called brown coal, at its Hambach mining site, an RWE spokeswoman said, following a court ruling that will delay plans to expand it by clearing an ancient forest.
* Local lignite mined in Germany is not traded in a transparent fashion but tends to directly supply nearby power generation plants.
* The Hambach news could be good for hard coal if generators needed substitutes to maintain the overall share of coal generation, traders said, adding that alternatively, competing energies might obtain market shares lost by lignite.
