France has historically been one of Europe’s lowest-cost electricity markets, thanks to its dominant nuclear power developments sector. However, significant nuclear availability problems in recent years and rising carbon prices have disrupted this advantage. In 2026, French electricity prices are on a recovery path — but the structural changes in the market are permanent.
Nuclear Recovery
EDF, France’s state-controlled utility and operator of the country’s 56-reactor nuclear fleet, suffered a significant operational crisis in 2022–2023 when stress corrosion issues required the shutdown of numerous reactors for inspection and repair. At the trough, French nuclear availability fell to multi-decade lows, forcing the country to import electricity from neighbours and contributing to the European energy crisis.
By 2025 and into 2026, nuclear availability has recovered substantially, with EDF completing inspection and repair programmes across affected units. The improved availability has allowed France to resume its traditional role as a net electricity exporter and has provided downward pressure on French electricity wholesale prices.
Regulated Tariffs: The TRVE
French residential electricity consumers benefit from a regulated tariff (the TRVE — Tarif Réglementé de Vente d’Électricité) set by the government, which provides some insulation from wholesale market volatility. The government used price shields and tariff controls extensively during the 2022–2023 energy crisis to protect consumers from the full impact of surging wholesale prices.
The Nuclear Investment Agenda
France has committed to a major nuclear investment programme, with EDF planning to build six new EPR2 reactors and explore life extension for the existing fleet. This long-term investment in nuclear capacity will be central to France’s electricity system through the middle of the century.
