LONDON (Reuters) -National Grid said on Thursday it was confident Britain would have sufficient electricity supplies this winter despite the closure of some nuclear units and uncertainly over coal plant availability, although there may be periods of tightness.

Britain's National Grid (LON:NG) is responsible for overseeing the country's energy supply and making sure supply and demand are evenly balanced.

"While we remain confident there is sufficient supply to meet peak demand, we should prepare for some tight periods during the winter," National Grid's Electricity System Operator (ESO) said in an early winter outlook published on Thursday.

National Grid ESO forecast its underlying average cold spell electricity peak demand at 59.5 GW which "assumes that there is no suppression of peak demand in Winter 2021/22 due to the ongoing COVID-19 pandemic," the report said.

National Grid ESO said its base case for de-rated margin, which is a measure of the amount of excess capacity expected above peak electricity demand, is currently 4.3 gigawatts for Winter 2021/22, or 7.3% of capacity.
