France breaks EDF’s grip on hydropower with law to auction 6 GW a year

TL;DRFrance’s Parliament adopted a bill that breaks EDF’s near-monopoly on hydropower by converting concessions to permits and requiring annual auctions of 6 GW. The reform ends more than a decade of EU legal pressure and could unlock billions in pumped-hydro investment.

France’s Parliament adopted a bill on Tuesday that dismantles the monopoly Électricité de France has held over the country’s hydropower market for decades, according to Bloomberg. The law converts EDF’s hydropower concessions into permits and requires the state-owned utility to auction 6 gigawatts of capacity each year under the supervision of France’s energy regulator, CRE.

EDF operates 20.5 GW of hydroelectric dams, roughly 80% of mainland France’s hydropower capacity. That dominance has drawn EU scrutiny since 2005, when the European Commission opened infringement proceedings against France for granting incumbent operators a preference right that effectively locked out competitors.

The bill replaces the old concession system with a permit-based model. Crucially, it opens auctions not just to energy suppliers but also to manufacturers, broadening the pool of potential bidders.

A workspace designed for growth, collaboration, and endless networking opportunities in the heart of tech.

Independent experts and the energy regulator will assess what EDF is owed in compensation for the termination of its existing concessions. The first auctions are scheduled to begin within 18 months, though previous attempts to reform the hydropower market stalled for more than a decade, and the timeline remains aspirational.

Engie’s subsidiary Shem, which operates 785 MW of hydropower capacity, must also convert its concessions to permits. CNR, a separate hydropower operator that is 50% owned by Engie, is exempted from the overhaul.

EDF reportedly plans to invest roughly €4.5 billion ($5.2 billion) over the medium term to add 4 GW of new capacity, mostly in pumped-hydro storage. The figure, first reported by Bloomberg in February 2026, has not been independently confirmed by EDF in its public filings.

Pumped-hydro systems store energy by moving water between two reservoirs at different elevations, acting as giant rechargeable batteries for the grid. France already has about 5 GW of pumped-hydro capacity, and new installations would boost both on-demand renewable generation and storage at a time when AI data centres are placing unprecedented strain on European electricity grids.

The investment would place EDF in a growing field of energy companies racing to meet AI-driven power demand. Nuclear startu
