Power imports from the continent cost Britain more than £250m a month in the second quarter of the year.
Figures from the latest Drax Electric Insights report show electricity imports have reached record levels, with 19.8% of demand met by overseas sources over the three months to June.
More than a tenth of electricity came from France alone. Overall, Britain imported 12.2 TWh last quarter, more than the country’s nuclear output (10.7 TWh), and close to total production from fossil fuels (13.6 TWh).
Dr Iain Staffell of Imperial College London, who leads the quarterly Drax Electric Insights report, said: “Fewer dispatchable generators means less competition and higher prices, making cheaper electricity from the continent much more attractive to import.
“The government must be mindful of the need to retain sufficient dispatchable generation capacity on our system for both energy security and affordability reasons as it works towards its ambition of having a clean power grid by 2030.”
