Customers with EDF’s Peak Hours/Off-Peak Hours plan may see their eight daily hours of cheaper electricity changed. According to an EDF guide updated on October 26, 2026, customers who have not yet received the new schedule will be notified between November 4, 2026, and November 30, 2027.
The current off-peak periods in the morning, from 7 a.m. to 11 a.m., and in the evening, from 5 p.m. to 11 p.m., are gradually being replaced by schedules that vary according to the season. Customers will still have eight off-peak hours per day, including at least five consecutive hours overnight. The new structure can also include up to three off-peak hours in the afternoon.
The change is linked to electricity production from solar panels, which is particularly high around the middle of the day. The French Energy Regulatory Commission changed the relevant rules in March 2025, while grid operator Enedis is responsible for implementing them. The CRE says that 3.5 million of the 14.5 million customers on off-peak tariffs, across all suppliers, were already following the new rules, leaving around 11 million households to be transferred.
Customers do not need to take any action. Under information cited by Service Public, their supplier must notify them at least one month before the change. EDF customers can check their schedules in their online customer account. Those whose current off-peak hours include a period between 7 a.m. and 11 a.m. or between 5 p.m. and 11 p.m. will see them changed.
Schedules provided between November 1, 2025, and May 31, 2026, will not be changed again. During winter, from November 1 through March 31, off-peak hours will remain concentrated mainly overnight. Afternoon off-peak periods will become more common from April 1.
The changes do not affect the Tempo plan, and the new rules do not apply in Corsica or France’s overseas territories.
