France to Adjust Off-Peak Electricity Hours Starting November 2025

The changes aim to align off-peak hours with solar energy production and evolving consumption patterns, impacting 11 million households by 2027.

The Commission de régulation de l'énergie (CRE) will shift off-peak electricity hours to align with periods of abundant solar energy, particularly during the afternoon in summer months.
The new off-peak schedule will start rolling out on November 1, 2025, with full implementation expected by the end of 2027.
Approximately 11 million of the 14.5 million households on off-peak contracts will see changes, while 3.5 million households with already optimized schedules will remain unaffected.
Consumers will retain eight off-peak hours daily, with five hours at night and up to three hours during the day, varying between summer and winter periods.
The changes are designed to reduce electricity costs during off-peak hours and enhance grid stability by better matching supply and demand patterns.
