EU Daily Renewables: UK to See High Wind Output Next Week

Latest forecasts show an upward revision in wind power forecasts across CWE for next week but output across the region will be relatively low, likely to support some fossil-fuel burn. In the UK, forecasts for wind output have been significantly revised up to reach load factors of up to 48% next week.

• German combined onshore and offshore wind output is forecast at 1.9-12.9GW during base load in the period to 30 September. Output has been revised up from Sunday onwards, while forecasts have been revised down for this week. Peak hour solar PV output is forecast at 10.2-20GW during the same period.
• French solar PV output has been revised down to reach 3.7-6.6GW during peak-load hours in the next nine days. Base load wind output has been revised up to 1.4-6.2GW in the period to 30 September.
• French nuclear reactor availability has risen to 67% this morning, up from 65% the day before, however, availability is likely to be lower today due to an extended halt at the Flamanville 1 reactor.
• In the UK, wind output is forecast at 6.1-13.3GW during base-load hours, equal to load factors of 22-48%, in the period to 28 September.
• Swiss hydropower reserves last week were stable week on week at 84.6% of capacity, or 7.54TWh, as of 18 September, widening the deficit to the five-year, BFE data show.
• The German Epex Spot base load edged higher on the day by €0.92/MWh to €103.98/MWh, from €49.46/MWh, narrowing the premium to the French market to €18.34/MWh, from €20.15/MWh a day earlier.
• The GB Epex Spot base load rose to £84.8/MWh, from £82.95/MWh the day before amid lower wind power generation.
