German and French wind power supply is set to remain above average until Thursday, when stiller, warmer weather is forecast to take over, even as analysts expect a drop on Monday.
The German Monday baseload contract (TRDEBD3) was untraded at 0855 GMT but had a bid price at €80 per megawatt-hour, above the €61/MWh closing price for Friday.
The French Monday baseload (TRFRBD3) was similarly untraded.
On the supply side, German wind output was expected to fall by 9.2 gigawatts to 21.2 GW on Monday, while solar supply was forecast to drop 5.5 GW to 15.1 GW, LSEG data showed.
Wind supply is expected to stay strong through early next week before high pressure takes hold from around next Thursday, although hydro remains deeply constrained with low rainfall and high temperatures, said analysts at Engie's EnergyScan.
"For the spot market, this should yield a near-term bearish bias on renewables, then a firm bullish pivot as wind fades and heat intensifies across the region from mid-next week," they said.
French wind output was expected to dip 610 megawatts to 2.8 GW and demand is expected to rise nearly 2 GW as average temperatures rise 4.2 degrees Celsius to 27.5 C, LSEG data showed.
French nuclear availability rose four percentage points to 60% of total capacity as two reactors returned from planned outages.
High temperature warnings persist for the Saint Alban nuclear plant on the Rhone river in eastern France, operator EDF said.
LSEG forecasts showed that Rhone river temperatures could go over the cooling temperature threshold on July 14, requiring a reduction in power.
The Golfech and Blayais plants are facing warmer water temperatures next week, LSEG data showed, which could lead to production restrictions.
The flow rate on the Garonne river in the south is also dropping to near the threshold where it could force power reductions at the Golfech nuclear plant, LSEG data showed.
