The French Parliament has finally adopted the state’s 2025 budget. Most notably, it includes a new scheme to redistribute the income generated by the operation of historical nuclear power plants to consumers, replacing the regulated access to historical nuclear electricity (ARENH) mechanism which ends on 31 December 2025. The new mechanism introduces a tax on the use of nuclear fuel for electricity production, applied when the income from the operation of EDF’s nuclear plants exceeds a certain threshold. If the income exceeds this "taxation threshold," 50% of the revenue above this threshold will be collected. If the income surpasses a second, higher threshold, called the "capping threshold," 90% of the revenue above this second threshold will also be collected. In addition, it creates a scheme to reduce electricity prices by lowering any price previously agreed between suppliers and their customers, or, if applicable, the price resulting from regulated electricity tariffs (TRVE).
In addition, the French 2025 budget adjusts standard excise rate following the end of the tariff shield to ensure a 9% reduction in the regulated electricity price for consumers starting from 1 February 2025. It also maintains the European minimum tax rate for energy-intensive industrial activities until 31 December 2025.
