France ends EDF's monopoly on hydropower with new auction legislation.

      **TL;DR** France’s Parliament passed a law that disrupts EDF’s near-monopoly on hydropower by transforming concessions into permits and mandating annual auctions of 6 GW. This reform ends over a decade of EU legal pressure and could unlock billions in pumped-hydro investments.

      On Tuesday, France’s Parliament enacted a bill that dismantles the longstanding monopoly Électricité de France (EDF) has maintained over the nation’s hydropower market, according to Bloomberg. The new legislation converts EDF’s hydropower concessions into permits and requires the state-owned company to auction off 6 gigawatts of capacity annually, overseen by France’s energy regulator, CRE.

      EDF runs 20.5 GW of hydroelectric plants, which accounts for about 80% of mainland France’s hydropower capacity. This significant dominance has attracted EU scrutiny since 2005, when the European Commission initiated infringement proceedings against France for giving existing operators preferential rights, effectively stifling competition.

      **What the law changes**

      The bill replaces the previous concession framework with a permit-based system. Notably, it opens the auctions not only to energy suppliers but also to manufacturers, expanding the pool of potential participants. Independent experts, along with the energy regulator, will evaluate what compensation EDF deserves for the cancellation of its existing concessions. The initial auctions are planned to commence within 18 months, although prior efforts to reform the hydropower sector have stalled for over a decade, making this timeline ambitious.

      Engie’s subsidiary Shem, which operates 785 MW of hydropower capacity, is also required to transition its concessions to permits. Conversely, CNR, another hydropower player partially owned by Engie, is exempt from these reforms.

      **EDF’s investment plan**

      EDF is reportedly looking to invest approximately €4.5 billion ($5.2 billion) over the medium term to increase capacity by 4 GW, primarily through pumped-hydro storage. This investment, initially reported by Bloomberg in February 2026, has not been independently verified by EDF in its public disclosures.

      Pumped-hydro systems function by transferring water between two reservoirs at different heights, serving as enormous rechargeable batteries for the power grid. France currently has around 5 GW of pumped-hydro capacity, and new projects would enhance both renewable generation and storage at a time when AI data centers are placing unprecedented demands on European electricity networks.

      This investment positions EDF within a competitive landscape of energy companies striving to meet increasing AI-driven power needs. Nuclear startups like X-Energy have achieved billion-dollar valuations on similar premises, although EDF’s investment in pumped hydro is less prone to technological risks compared to advanced reactor designs.

      **Why it took so long**

      The European Commission commenced infringement proceedings against France in 2015 and again in 2019 due to the nation’s inability to open the hydropower market to competition. France had initially committed to reforming the system in 2010, but a government change in 2012 stalled progress.

      Subsequent administrations viewed the situation as politically sensitive. Regional officials and energy trade unions opposed what they viewed as the privatization of a vital national resource, while EDF lobbied to maintain control over infrastructure it has managed for generations.

      The new law ostensibly addresses the EU dispute. Whether France adheres to the 18-month auction timeline or if the reform faces further delays in implementation will determine if the market genuinely opens to new competitors or continues to be dominated by EDF, albeit with a new regulatory facade.
