What Seolis does

Seolis (legal name SÉOLIS, SAEML à directoire et conseil de surveillance) is one of France's largest Entreprises Locales de Distribution (ELD), serving approximately 150,000 customers — and via its GÉRÉDIS Deux-Sèvres distribution subsidiary over 165,000 customers across 259 communes — in the Deux-Sèvres department. Founded in its original form in 1923 as the Syndicat Intercommunal d'Énergie des Deux-Sèvres (SIEDS), the company operates under a mixed-economy (SAEML) governance model with parent-oversight by SIEDS and a share capital of €72,116,000, employing approximately 380 staff across headquarters and 5 customer agencies (Niort, Melle, Bressuire, Thouars, Châtillon-sur-Thouet).

The company operates across the full multi-energy value chain via a portfolio of subsidiaries: electricity and gas supply under regulated tariffs (Tarif Bleu residential, Tarifs Jaune/Vert for professionals) and competitive offers; GÉRÉDIS managing 15,000+ km of distribution lines as France's 3rd-largest network operator; SÉLIA supplying electricity and gas nationally outside the historical territory; SÉOLIS PROD generating renewable energy from photovoltaic (including an 11 MWc Bedenac farm) and hydroelectric (Hydro'nov) sources; Séolis Mobilités operating the AlterBase EV charging network (100+ stations) and BioGNV biomethane stations; plus gas-network construction, the IRIS public-lighting package with Lum'IRIS management tool, Fêt'IRIS heritage illumination, and CEE energy-savings programs.

The business model combines regulated subscription-style revenue from electricity and gas tariffs (Tarif Bleu, Jaune, Vert), propane subscription with annual fixed pricing, usage-based revenue from EV charging and renewable production, managed-services revenue from public lighting and gas-network management, and professional-services revenue from CEE programs and energy-renovation support. Sales are conducted through a sales-led motion combining agency, integrated call center, online self-service portal, public procurement tenders for local authorities, and subsidiary channels (SÉLIA nationally). The company holds ISO 9001, 14001, 45001 and ILO OSH certifications, a regulated 89/100 gender equality index (2025), and a 94% overall customer satisfaction rate (2022).

Broad incumbents

• Engie: France's largest natural gas and multi-energy operator with electricity retail, district heating, and energy services. Comparable as a broad incumbent operating in natural gas distribution, electricity supply, and energy efficiency—directly competitive with SÉOLIS's multi-energy value proposition.
• EDF (Électricité de France): France's national electricity incumbent providing generation, transmission, distribution, and supply across the entire country. Comparable as the dominant regulated electricity supplier and network operator; competes with SÉOLIS on territorial supply and is the historical supplier from which ELDs historically carved out local franchises.
• TotalEnergies: Major multi-energy supplier offering electricity, gas, and EV charging to residential and business customers across France. Comparable as a national retail competitor that SÉOLIS/SÉLIA must compete with outside the historical Deux-Sèvres territory, particularly in market offers.

Direct peers

• Régie d'Électricité de Saverne: Local municipal régie distributing electricity in the Saverne area of Alsace under regulated tariffs. Comparable to SÉOLIS as a small-to-mid sized French ELD with similar municipal ownership and regulated supply model.
• UEM (Usine d'Électricité de Metz): French ELD operating in the Metz region with multi-energy supply (electricity, gas), district heating, EV charging, and fiber/telecom services. Directly comparable to SÉOLIS as a similarly structured municipal-anchored multi-utility serving a defined French territory with comparable product breadth.
• SORÉGIES: Vienne-area local distribution company supplying electricity, gas, and fiber services. Closely matches SÉOLIS's structure as a French ELD with mixed public ownership, regulated supply, and diversified energy service offerings within a single department-level territory.
• Vialis: Colmar-region multi-energy utility (electricity, gas, water, fiber, EV charging) operating under similar ELD/regulated framework in Alsace. Directly comparable in scope of activities, customer segments, and municipal-driven governance model.
• ÉS (Énergies de Strasbourg): Historic Strasbourg-based ELD providing electricity, gas, and energy services to residential, business, and municipal customers in Alsace. Comparable to SÉOLIS as a regulated multi-energy local distributor with similar municipal governance and integrated service portfolio.
• SICAE (multiple regional entities): Federation of SICAE rural electricity cooperatives providing regulated supply and distribution across multiple French territories. Comparable to SÉOLIS as a regulated multi-territory ELD network offering electricity supply, gas, and ancillary services to residential and business customers.

Emerging players

• Alterna: Independent French energy supplier offering electricity and gas to residential and business customers outside the regulated tariff framework. Comparable as an alternative supplier competing for customers in the open market segment that SÉLIA targets for national expansion.
