Power generated by renewable energy sources exceeded the electricity generated by gas during the last four months.
Between 1 October and 28 February, power generated by wind, hydro and solar reached 47TWh, according to the Energy Climate Intelligence Unit (ECIU).
During the same period, 46TWh of electricity was generated by gas.
Other sources of generation, including nuclear and biomass, generated 28TWh over the winter period.
The renewable energy figure represents a year-on-year increase of 4TWh on last winter.
Across the whole of 2022, the UK renewable power capacity grew by 3.4GW compared to 2021.
Jess Ralston, head of energy at ECIU, said: “We’re seeing the old electricity system give way to the new, with renewables becoming the backbone and displacing more and more gas.
“Battery storage is ramping up faster than expected, boosting the UK’s energy security and leaving us less exposed to international gas markets.
“Lifting the ban on onshore wind will help. But with the US and the EU going gangbusters for renewables, eyes are on the government, the chancellor and the Budget to decide on how the UK stays an attractive market for the investments that will ultimately bring down bills.”
According to the ECIU’s analysis, the UK would have needed to import 22% more gas during the winter without its renewable energy production.
Due to its increases in renewable power generation, the UK became a net electricity exporter in 2022 for the first time since 2010 and electricity exports in the third quarter of 2022 were eight times higher than in the same quarter the previous year.
The ECIU analysis follows a Drax Electric Insights report which revealed that Britain broke the record for “greening its grid” after producing 100% clean electricity for 25 hours in December, the longest period on record.
