The operator said it anticipated a margin of around 4.4 GW, or 7.4 per cent excess generation at peak times, which is slightly higher than last year’s 3.7GW.

It said a combination of factors were responsible for the higher margins for this winter, including more generation being available, as well as increased levels of battery storage.

Last winter, the energy markets across Europe were able to cope with consumer demand, despite record-high prices of gas and oil driven by the Ukraine war.

Coordination and cooperation across European electricity systems helped to meet the demand – if one country was producing excess energy, interconnectors would be used to transport this to other areas of the continent where demand outstripped supply.

This winter, both European gas storage and French nuclear power have greater availability than last year, the ESO said, which will help to support electricity and gas flows across Europe into Great Britain.
