Energy system operator expects winter power supplies to outstrip demand by almost 9% this year

The risk of winter blackouts in Great Britain has tumbled to its lowest in four years even after the shutdown of the UK’s last coal plant, thanks to investments in low-carbon electricity sources.

The National Energy System Operator (Neso) expects Britain’s winter power supplies to outstrip demand by almost 9% this year in its base case scenario, the greatest margin since the winter of 2019 to 2020.
