SDESM

What SDESM does

SDESM (Syndicat Départemental des Énergies de Seine-et-Marne) is a public cooperative syndicate established under French public law, headquartered in La Rochette, France, and operating as the principal organizing authority (autorité organisatrice) for energy distribution across the Seine-et-Marne department. Founded in 2014 and governed by elected officials of its member municipalities, SDESM aggregates demand across 458 communes and 5 EPCI (inter-municipal cooperation establishments) to deliver coordinated public procurement, infrastructure management, and energy transition services that individual small municipalities could not achieve independently. The organization oversees 6,123 km of electrical networks, 1,674 km of gas distribution networks, and 305 installed EV charging points, and exercises regulatory control over Enedis as the distribution network concessionaire in the territory.

Its core service portfolio spans public lighting management, low-voltage network burial and reinforcement, renewable energy project development (solar, geothermal), electric mobility infrastructure, bulk energy purchasing, and energy renovation of public buildings. The two proprietary technology components anchoring operations are the arcOpole Pro Geographic Information System (SIG) portal for spatial infrastructure management, and the SAGA CITY computerized maintenance management system (GMAO), which georeferences more than 60,000 public lighting points and extends to field operators via the SAGA Mobile V2 application on iOS and Android for fault reporting and maintenance tracking.

The business model is a public membership-based syndicate structure. Revenue mechanics derive from member contributions, coordinated public procurement contracts routed through the marches-securises.fr platform, and subsidy co-financing from institutional partners including ADEME, the Région Île-de-France, and the Fonds vert. Pricing is not publicly disclosed and varies by project scope. SDESM runs a lean operating team of 11–50 employees and operates exclusively within the Île-de-France region of France, with no geographic expansion or commercial productization signaled. Its sole mixed-economy subsidiary, Bi-Métha 77 (biomethane production), was discontinued in 2025 and is in dissolution, expected to conclude by end of 2026.

Core offering

SDESM is a French public departmental syndicate that coordinates electricity distribution, low-voltage network burial and reinforcement, public lighting maintenance and renovation, renewable energy project support, electric vehicle charging infrastructure deployment, and bulk energy purchasing on behalf of its 458 member municipalities and 5 EPCI in Seine-et-Marne. It operates the arcOpole Pro Geographic Information System for territorial infrastructure mapping and the SAGA CITY computerized maintenance management software for managing public lighting assets.

Product overview

SDESM operates as a unified public energy distribution authority for Seine-et-Marne, offering an integrated portfolio of infrastructure and energy services. The core offering centers on public lighting management (Éclairage public) supported by the SAGA CITY GMAO software platform, alongside network infrastructure services including underground burial and extension of electrical networks. SDESM also coordinates renewable energy projects, electric vehicle charging infrastructure (mobilité décarbonée), and bulk energy purchasing for its 458 member municipalities. A Geographic Information System (SIG/arcOpole Pro) provides spatial data services, while concessionaire control services ensure quality monitoring of electricity and gas distribution. The organization functions as a coordinating authority rather than a technology product company, providing public services to local governments.
