The UK avoided the need for gas imports worth £1bn in March 2026 thanks to record electricity generation from wind and solar, reveals Carbon Brief analysis.
Wind generation hit a new record for the month of March on the island of Great Britain, up 38% year-on-year, while solar nearly matched the output of last year’s exceptionally sunny spring.
Together, wind and solar generated 11 terawatt hours (TWh) of electricity in March 2026, up a combined 28% and setting a new record for the month, as shown in the figure below.
This record wind and solar output avoided the need to import 21TWh of gas – roughly 18 fully loaded tankers of liquified natural gas (LNG) – which would have cost around £1bn at current high prices due to the Iran war.
(This is based on gas costing 130p per therm, or £44 per megawatt hour, compared with the range of 120-170p per therm seen over the past month.)
At the same time, the record output from wind and solar saw electricity generation from gas falling 25% year-on-year in March 2026 to the lowest level ever recorded for the month.
This meant that gas was setting the price of electricity roughly 25% less often in March 2026 than in the same month in 2022, when fossil-fuel prices spiked after Russia’s invasion of Ukraine.
