What Volterres does

Volterres SAS is a French renewable electricity supplier and aggregator founded in 2019, headquartered in Paris, and operating as a wholly-owned subsidiary of Swiss energy group BKW following the June 2026 acquisition. The company serves three primary customer segments: large multi-site enterprises (C2-C4 clients on the Enedis network), public sector entities including municipalities, métropoles, and energy syndicats, and residential "riverain" customers living near partner renewable production sites. It supplies more than 40,000 delivery points with approximately 2+ TWh annually as of 2025, targeting 2.5 TWh in 2026, and works with a network of 90+ independent renewable energy producers across 8 French metropolitan regions.

The core platform is R.E.D.S. (Renewable Energy Digit System), a blockchain-based traceability system operational since 2020 that records renewable electricity attribution at 30-minute intervals from producer to consumer, enabling verifiable proof of origin and geographic provenance beyond what standard Garanties d'Origine certificates provide. Supporting modules include Autoconso Digitale (digital self-consumption for projects above 500 kWc), PPA/CADER facilitation and advisory, independent producer aggregation and valorization services, and RéFlex, a dynamic pricing product launched in February 2026. R.E.D.S. won the Solar Impulse Efficient Solution label in 2020 and the Tenerrdis competitiveness cluster label.

Revenue derives from multi-year electricity supply contracts to enterprise and public clients, aggregation and balance responsibility services for independent producers, PPA advisory and brokerage, and complementary supply contracts layered onto direct producer-buyer PPAs. Pricing is quote-based for B2B and competitive with regulated tariffs for eligible riverain offers. The company secured consecutive Top 3 placement in the 2024-2025 CLEEE-FNCCR B2B electricity supplier barometer (up from Top 5 in 2021-2023) and holds ADEME's VertVolt label for its residential offers. Notable customers include the French Ministry of Defense, MAIF, Carglass, Région Bretagne, SIDEC (82 communes, 1,700 sites), Nantes Métropole (53 GWh), Altarea, and Radio France.
