Electricity pricing in France has shown significant volatility and divergence between regulated and dynamic consumer options. In late July 2026, major suppliers EDF and Engie introduced weekend-specific tariffs, offering discounts of up to 34% compared to regulated prices for consumers who shift usage to Saturdays and Sundays via smart-meter technology.

By August 2026, price trends diverged further. While regulated tariffs saw an average increase of 2.5% due to higher network usage fees and supply security mechanisms, consumers on dynamic pricing plans experienced periods of zero-cost electricity. These zero-cost slots occurred during windows of high renewable energy production and low demand, though consumers remain liable for taxes, subscription fees, and transmission costs.
