EDF's fortunes had already taken a hit after the government ordered it last month to cap electricity bills for French clients, even as prices have spiked on global markets.

The measure, which was enacted just weeks before Macron is expected to seek a second term in April, infuriated critics who accused him of electoral posturing that would cost the company some eight billion euros ($9.1 billion).

While EDF normally generates the bulk of its electricity from its network of 56 nuclear reactors across France, many are near the end of their 40-year lifespans and around a dozen have been shut or will be soon to carry out safety inspections over corrosion risks.

That will force the group to buy power on the European market, expected to cost it some 11 billion euros this year -- even as its total debt load now stands at 43 billion euros.

"EDF is experiencing problems linked to reactor outages, it's selling less nuclear power, and so it's revenues are down and it needs financial support from the state," Finance Minister Bruno Le Maire told RTL radio.

This month Macron announced plans to build as many as 14 new next-generation EPR2 reactors to reduce the country's reliance on fossil fuels, which EDF has said could cost some 50 billion euros.

EDF has also been corralled into buying the nuclear turbine operations in France from the American conglomerate GE, which had bought the business just six years before when Macron was finance minister.

Le Maire said the government would inject 2.1 billion euros as part of an upcoming capital increase, while the company announced plans to sell assets worth three billion euros in the coming years.
