Transmission system operator National Grid predicts that the UK will be able to generate around 10% more electricity than the peak demand this winter.

The margin, which was revealed as part of the company’s winter outlook report, is higher than last winter’s 6.6% and the previous winter’s 5.1%.

The 6GW margin is higher than in previous winters because power stations that have not won capacity markets contracts have indicated that they will be available to provide back-up electricity.

National Grid said it was “confident that we have the right products and strategy in place to help us to balance the system, even under colder conditions than we have experienced in recent years”.

Gas from Rough

Around one billion cubic metres (BCM) of gas is expected to be withdrawn from Centrica’s soon-to-close Rough storage facility over the winter.

National Grid said: “Total gas demand for the winter is forecast at 51BCM, with a peak demand forecast for a one-in-20 winter of 502 million cubic metres per day.

“We expect there to be sufficient gas available to meet this demand.”
