SNCF Energie, the energy subsidiary of SNCF Voyageurs, has signed four corporate power purchase agreements (PPAs) with French renewable energy producer Neoen, securing 137 GWh of solar power annually for a period of 20 to 25 years.

According to Neoen, the contracts, signed in July, will come into effect on 1 January 2026 and cover the output of four solar farms with a combined capacity of 111 MWp. The plants—Romilly (42 MWp, Grand-Est), Loirécopark (39 MWp, Sarthe), Champblanc (15 MWp, Charente) and Labouheyre (14 MWp, Landes)—will supply enough electricity to cover the yearly needs of the 11,000 high-speed train trips between Paris and Bordeaux.

Hedging against price volatility The PPAs will provide Neoen with long-term revenue to operate its assets and finance growth, while enabling SNCF Voyageurs to shield itself from fluctuations in wholesale electricity prices. “This partnership is a clear illustration of the role played by local regions in the nation’s energy transition,” said Guillaume Decaen, CEO of Neoen France.

He highlighted that the projects were developed in collaboration with local stakeholders.

Xavier Barbaro, Group CEO of Neoen, added that the deal demonstrates the “high quality” of the company’s projects and its ability to build “long-term relationships” with major industrial players. Advancing SNCF’s energy transition SNCF Voyageurs, which accounts for 11% of passenger transport in France but less than 1% of transport-related greenhouse gas emissions, is accelerating its renewable energy strategy. The company aims to source 40–50% of its electricity from renewable energy by 2027–2028, with 20% of that secured through corporate PPAs, according to Neoen.
