PARIS, Nov 24 (Reuters) - A planned French windfall tax on energy companies' profits during Europe's current energy crisis would likely cost debt-laden nuclear giant EDF (EDF.PA) around 5 billion euros ($5.20 billion) next year, newspaper Les Echos reported on Thursday.
The levy, which is part of the 2023 fiscal bill parliament is currently deliberating, would make EDF by far the biggest contributor to the scheme, Les Echos said.
EDF, the operator of France's nuclear plants and many renewables sites, declined to comment.
The French government intends to trigger the levy at 100 euros per megawatt hour (MWh) for nuclear and renewable energy production.
The move will further strain EDF finances, which after various profit warnings this year linked to problems at its nuclear reactors, is in the process of being fully nationalised.
