Low carbon power sources provide most of Britain's electricity over winter period

The figures are being released at the end of our fortnightly Winter Power Update, which has been providing regular updates of our generation statistics covering 1st November 2022 to 28th February 2023, when demand is usually at its highest.

The final figures show that overall, during the winter period, onshore and offshore wind provided 60% of our low carbon power (31.4 TWh), followed by nuclear which generated 26% (14.34 TWh) - enough to power 14 million British homes all year round.

This increased Britain’s energy security over the winter by reducing the demand for imported gas by over 9.7 billion cubic meters (or over 66% of total Liquified Natural Gas imports) – saving British consumers over £15,700,000,000.

RenewableUK’s Executive Director of Policy Ana Musat said: “These latest figures show that low carbon power sources, led by wind, played a central role in keeping the lights on this winter by providing the lion’s share of Britain’s electricity. Reliable homegrown clean energy is boosting our energy security and saving hard-pressed British consumers billions of pounds in expensive gas imports, as well as moving us closer towards net zero. Now we need to ramp up the roll-out of new clean energy projects as fast as possible to maximise the benefits of renewables to billpayers and businesses in the years ahead”.
