SDE 24

What SDE 24 does

SDE 24 (Syndicat Départemental d'Énergies de la Dordogne) is a French public territorial entity founded in 1937, headquartered in Périgueux, with statutory authority over the public electricity and gas distribution service across all 503 communes of the Dordogne department. It owns public distribution network assets under a 2020-2050 concession contract with Enedis and EDF, manages 81,250+ public lighting points via its Régie 24 maintenance division, and oversees gas distribution to 47,000 customers across 86 communes through GRDF and propane concessionaires (Antargaz, Primagaz). The organization operates a multi-service platform spanning electricity network extensions and undergrounding, public lighting modernization (the €36M 'Nouvelle Donne' LED program across 193 communes through 2033), sustainable mobility infrastructure (the Mobive EV charging network of 154 stations in Dordogne and 1,100+ across Nouvelle-Aquitaine, plus the Témob BioGNV network), and a low-carbon strategy encompassing energy audits, renewable heat development, CEE subsidies, and a Groupement d'achat d'énergies.

The organization's business model is non-commercial and structured around public-sector financing: services are funded through mandatory member contributions from the 503 communes, public investment programs (national, regional, EU), and concession oversight fees rather than consumer pricing. Energy tariffs are regulated nationally. SDE 24 created SEM 24 Périgord Énergies in 2017 as a mixed-economy company with Crédit Agricole Charente-Périgord, Groupe Sorégies, and La Banque des Territoires to invest directly in renewable energy production (photovoltaic, hydroelectricity, methanization). With only 24 employees, SDE 24 operates a lean coordination model, leveraging concessionaires (Enedis, GRDF, NaTran) for execution while retaining regulatory authority, asset ownership, and strategic planning functions. The technology stack includes the proprietary Candela software for lighting asset management, real-time EV charging availability tracking across the regional Mobive network, and the SDIRVE strategic deployment plan for charging infrastructure approved September 2023. In May 2026, Lionel ARMAGHANIAN was elected President, succeeding Philippe DUCENE who led the organization since 2008.
