These approaches can be complemented by estimating the impact of a change in the discount rate on the discounted value. The following table reports these details for the main components of EDF’s provisions for the back-end of the nuclear cycle, decommissioning of nuclear plants and last cores:

Other provisions for decommissioning Note 29

Other provisions for decommissioning principally concern fossil-fired power plants. The costs of decommissioning fossil-fired power plants are calculated using regularly updated studies based on estimated future costs, measured by reference to the

charges recorded on past operations and the most recent estimates for plants still in operation. The provision recorded at 31 December 2020 reflects the most recent known cost estimates and includes rehabilitation costs for generation sites.
