Enedis will implement a major reform of off-peak hours starting 1 November, under the framework of the public electricity network tariff (TURPE 7), defined by the Energy Regulatory Commission (Commission de régulation de l’énergie, CRE) in March. This revision aims to adjust electricity consumption schedules to align with solar energy production and the evolving usage patterns of consumers, such as programmable devices and remote working.
The measure affects 14.5 million customers subscribed to a peak/off-peak offer (HP/HC). Around 3.5 million of these customers already have time slots that comply with the new rules. For the remaining 11 million, the hours will be adjusted gradually between November 2025 and October 2027, following a two-phase implementation schedule.
Reorganisation of time slots to ease peak demand
All customers will retain eight off-peak hours per day, including a minimum of five consecutive hours at night. Enedis plans to shift up to three off-peak hours to the 11am–5pm window, particularly during the summer months, to absorb peaks in photovoltaic production. This redistribution is intended to relieve high-demand periods, typically observed in the morning and early evening.
The first phase, beginning on 1 November, will affect 1.7 million customers whose current schedules already allow partial compatibility. The second phase, starting in the second half of 2026, will cover an additional 9.3 million customers. This stage will also introduce seasonal differentiation between summer and winter off-peak hours. Professional and industrial users will be included in the final phase in 2027.
Automated deployment via Linky meters
All changes will be carried out remotely using Linky smart meters, already installed in most households. Automated devices, such as water heaters, can follow the new schedules provided they are connected to the meter via the dry contact. Electricity providers will notify customers at least one month before any time slot adjustment.
Enedis will adjust schedules based on local network conditions. The reform aims to shift up to 5GW of electricity consumption to sunny afternoon periods, reducing pressure on peak hours. The operation involves Enedis technical teams and electricity suppliers nationwide.
