La Française de l'Energie S.A. (FDE.PA) is an independent multi-energy producer focused on low-carbon and carbon-negative energy solutions from local resources, including abandoned mine methane, biogas, solar, flare gas, landfill gas, and rare gases; it generates and sells green electricity primarily through photovoltaic plants and combined heat and power units, natural gas via exploration and production such as coal bed methane using multilateral well drilling, heat for district networks, biogas purification and liquefaction into bio-LNG, bio-CO2, green hydrogen, and related services like cold energy recovery and exchangers. Founded in 2006 and headquartered in Faulquemont, France, the company operates mainly in France (Hauts-de-France, Lorraine), Belgium (Wallonia), and Norway, supplying regional players including households and industries to replace imported energy with cleaner local alternatives; net sales break down by green electricity (69.8%), gas (23.2%), heat (1.3%), and other activities including biogas units and hydrogen (5.7%). In February 2025, FDE strengthened its European platform through the acquisition of Alltec, a provider of EPC solutions for renewable natural gas, hydrogen, and solar projects particularly in Norway, enhancing execution capacity; the company reported FY2025 annual revenues of EUR 29.2 million (over EUR 34 million fully integrated), solid performance amid electricity price volatility, cash position of EUR 62.6 million, and robust growth prospects for 2026-2027 with a project pipeline exceeding EUR 100 million; earlier, it integrated Cryo Pur in 2022 for bio-LNG expertise and maintains subsidiaries like Gazonor, which secured a EUR 5.8 million ESG loan from Arkéa Banque.
