Others

• Signify (Philips Lighting): Signify is a global lighting OEM and smart-city systems integrator (Interact City) that supplies LED luminaires and connected lighting platforms to municipal contracts comparable to Cielis's LED transition program.
• Schréder: Schréder is a European outdoor lighting manufacturer and smart-city solutions provider with turnkey municipal lighting projects; comparable to Cielis as an adjacent ecosystem participant rather than a direct services competitor.

Broad incumbents

• Eiffage Énergie Systèmes: Eiffage Énergie Systèmes is one of Cielis's two 50% parents and operates electrical contracting, connected urban solutions, and energy infrastructure across France, offering directly comparable services to other municipalities outside Paris.
• Dalkia: Dalkia (EDF subsidiary) is Cielis's other 50% parent and a leading French energy services operator specializing in low-carbon city development, including public lighting, heating networks, and urban energy efficiency at scale.
• Engie Solutions: Engie Solutions is the broader energy and urban services arm of Engie providing public lighting, district heating, and integrated facility management across France and Europe; overlaps with Cielis on lighting services but operates at much wider scope.

Direct peers

• Citeos (Vinci Energies): Citeos is Vinci Energies' public lighting and urban equipment brand operating across France with similar municipal lighting/signaling contracts; it is the closest direct competitor to Cielis in the French municipal street-lighting services market.
• Bouygues Energies & Services: Bouygues Energies & Services operates urban infrastructure including public lighting, traffic systems, and smart-city equipment for French municipalities, competing head-to-head with Cielis in tenders like the 2019 Ville de Paris Marché Global de Performance.
• SPIE CityNetworks: SPIE CityNetworks is the French public-infrastructure division of SPIE, focused on public lighting, traffic signaling, and connected urban equipment under multi-year municipal contracts, directly comparable to Cielis's scope.
• Citelum: Citelum is an EDF/Dalkia subsidiary that manages public lighting and smart-city services for cities including Paris, Copenhagen and Rome. Cielis's name itself derives from Citelum, and the two share both parent ownership and the same municipal managed-services model.

Regional players

• Suez (Municipal Services): Suez operates urban infrastructure services (lighting, water, smart-city) across Europe; while not a direct lighting specialist, it competes for similar municipal performance contracts in French and European cities.
