With bills still "very high" compared to late 2021, "I'm giving us two years to end" electricity subsidies by early 2025, Bruno Le Maire told broadcaster LCI -- a day after vowing to slash France's debt and deficits with cuts to public spending.

State-owned energy firm EDF produced its lowest amount of electricity in 30 years last year, as many nuclear reactors -- the heart of France's energy system -- have been taken offline due to corrosion discovered in emergency cooling systems.

Energy prices have also been mounting across Europe from the throttling of the flow of Russian gas since Moscow attacked Ukraine last year.

Increases in electricity bills have been less sharp in France thanks to government subsidies, at four percent in 2022 and 15 percent this year -- at a projected cost of 45 billion euros ($49 billion) in 2023.

But Le Maire said there was "no longer a need to keep up" subsidies for gas, as prices have fallen back, vowing to end them this year.

The finance minister had on Thursday said it was time to cut public spending to rein in annual budget deficits and France's overall debt, one of the highest burdens in the 27-member European Union.

Both figures had swollen from Paris' "whatever it takes" response to the coronavirus crisis and the energy price surge.

"It's vital to speed up debt reduction" between now and the end of President Emmanuel Macron's second term in 2027, Le Maire insisted in an interview with regional daily Courrier Picard.
