EDF’s shares fall after French firm cuts nuclear output forecast


It slashed its nuclear output forecast for 2022 to 295-315 terawatt-hours from a previously expected 300-330 terawatt-hours, saying this was related to nuclear safety controls.

EDF’s shares, which have lost almost 40% since December, fell as much 3.5% on Tuesday, recovering some ground to trade 2% lower later on.

Analysts said falling nuclear power was encouraging the use of more fossil fuel-powered plants, driving up the price of carbon emissions permits which are closing in on 100 euros ($114) per tonne for the first time.

“The high carbon price impacts power prices directly since there are no alternatives for coal and gas generation in the short term, in periods where nuclear and renewables cannot cover demand, coal and gas are effectively setting power prices,” Rystad Energy analyst Fabian Rønningen said.

Jefferies analysts said extra energy EDF would have to buy would cost the equivalent of 8% of its market capitalisation.


EDF said its new output forecasts took into account known or suspected corrosion problems on 11 reactors. It said three – Chinon 3, Bugey 4 and Cattenom 3 – faced unscheduled shutdowns.

Two reactors had shutdowns extended. Penly 1’s shutdown would run to Oct. 31 and Chooz 1 would stay shut until Dec. 31.

The French and German forward curve power prices for 2023 hit contract highs after EDF’s downward revision, but stayed below highs of late December for rolling annual contracts.

EDF’s forecast shows nuclear output will fall by 2.5 to 3 gigawatts (GW) on average in 2022 and analysts said it raised concerns for 2023, given the risk of outages being extended.

EDF said it would announce its 2023 forecast “as soon as possible”.

French Environment and Industry Transition Minister Barbara Pompili said EDF was due to send the government a first report on safety-related nuclear outages in March, adding: “I have asked EDF for an audit because too many reactors are halted.”

The minister also said in her comments to French radio that EDF would buy a France-based operation that makes nuclear reactor turbines, worth about $1 billion, from General Electric. The unit had been owned by Alstom until 2015.

She said returning it to French ownership was a “logical move”.
