Solar generation reached a new record in Great Britain on 22 April 2026, hitting 14,426 megawatts at 11:30 and supplying 37% of the country’s electricity demand, according to data from Solar Energy UK and the National Energy System Operator (NESO).

The surge in output contributed to a record low reliance on fossil fuels across the electricity system. At the same time, natural gas accounted for just 2% of Great Britain’s electricity supply at both 11:30 and midday, generating approximately 799 MW during the peak solar period.

The new milestone surpasses the previous record of 14,414 MW set on 7 April 2026, highlighting the rapid pace of growth in solar generation capacity in recent weeks.

Households on agile energy tariffs benefited from periods of negative pricing during times of high solar output, as excess renewable generation pushed wholesale electricity prices below zero.

“What was once thought to be impossible is today’s reality: a grid being dominated by cheap, zero-carbon energy. This will become the norm as renewables grow ever faster, powering the economy and driving down prices for us all,” said Chris Hewett, Chief Executive of Solar Energy UK.
