What ELO énergie does

ELO énergie is a French SAS (private company) founded in 2006 and headquartered in Grandchamp des Fontaines near Nantes, operating with approximately 71 employees as a PME. It is a specialty engineering and construction firm focused on high and very high voltage (HTA, HTB) electrical infrastructure, delivering an integrated service that combines a bureau d'ingénierie with in-house field teams (Experts, Engineers, Technicians, Installers/Monteurs, Surveyors, Drone operators).

The company's service portfolio spans ten lines: substation studies and works (HTA/HTB), overhead line studies, underground cable studies, HV cable installation and testing, transformer assembly, HT/BT network construction, photovoltaic farm grid connection, wind farm grid connection (including offshore substations), topographic surveying (street surveys, network detection, laser scanning, 3D modeling), and R&D expertise. All work is delivered under a quote-based, project-based B2B model targeting enterprise clients.

Customers are concentrated in European electricity transmission and distribution (RTE, ENEDIS, EDF, ENGIE), HV equipment OEMs and cable providers (Siemens, NKT, Nexans, GE Grid Solutions, SGB-SMIT, PFISTERER), renewable developers (Technique Solaire), and offshore constructors (STX France/Chantiers de l'Atlantique for the Rentel wind farm). The firm operates across Europe, holds ISO 9001, ISO 14001, and MASE certifications (renewed through 2026), and won the RTE 'Excellence Industrielle' trophy in 2019. There are no disclosed funding rounds, and the €37,000 share capital is the French SAS legal minimum; revenue is not publicly disclosed.

Core offering

ELO énergie is a French engineering and construction firm specialized in high and very high voltage (HTA, HTB) electrical infrastructure. The company delivers engineering studies, construction, and installation services covering electrical substations, overhead transmission lines, underground cable connections, transformer assembly, and electrical network construction (HT/BT). It also performs grid connection works for renewable energy projects (wind and solar farms, including offshore substations) and provides topographic surveying using drones and laser scanning.

Product overview

ELO énergie is a specialized engineering and construction company for high-voltage electrical installations (HTA, HTB). The company operates a unified engineering and construction service model, deploying its in-house bureau d'ingénierie (engineering office) and field teams (Experts, Engineers, Technicians, Fitters/Monteurs, Surveyors, Drone operators) across Europe. Its core portfolio spans ten specialized service lines: (1) Electrical substation studies and works (HTA/HTB), (2) overhead line studies, (3) underground cable studies, (4) high-voltage cabling, (5) transformer assembly, (6) electrical network construction (HT/BT), (7) photovoltaic farm grid connection, (8) wind farm grid connection (including offshore), (9) topographic surveying (street surveys, utility detection, laser scanning), and (10) expertise and R&D. The company is structured as a single integrated service offering rather than a modular software platform.

• STX France (Chantiers de l'Atlantique)coreStrategic or Co-development Partner · 4 October 2017First partnership with STX France for offshore substation construction; ELO Energie served as contractor for transformer installation (GE Grid Solutions 33kV/220kV, 310 MVA), cable pulling, connection and testing for 33kV cables on the Q34 offshore substation for the Rentel offshore wind farm in Belgium. The consortium Otary (developing Rentel wind farm) chose STX France to design, build and install the electrical substation.

Scale indicators4 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Eiffage Énergie Systèmes: French electrical engineering and contracting subsidiary of Eiffage, active in HV/MV substations, transmission lines and renewable energy connections — overlapping end customers (RTE, ENEDIS, EDF) and service scope.
• Spie: French multi-technical services group with a dedicated 'Networks' / electrical infrastructure business line covering HV/MV substations, overhead lines and underground connections — directly comparable in service mix but at vastly greater scale and geographic reach.
• GE Grid Solutions: GE's grid business supplying transformers, switchgear and substation equipment; listed as a customer and partner (e.g. transformer supply on Rentel Q34) of ELO, with highly complementary scope in HV projects.
• Bouygues Energies & Services: Division of Bouygues Construction delivering electrical infrastructure projects including HV substations, distribution networks and renewable grid connections in France and internationally; comparable in offering and customer base.
• Vinci Energies (incl. Omexom, Cegelec): Major French-headquartered EPC group whose Omexom and Cegelec brands specialize in transmission, distribution and renewable grid connections globally; competes with ELO on HV substation EPC, cable laying and wind farm interconnections.

Regional players

• SGB-SMIT Group: European transformer manufacturer that appears among ELO's clients and partners; a comparable specialist in the HV transformer ecosystem, with adjacent (rather than directly competing) scope since ELO installs rather than manufactures.
• Chantiers de l'Atlantique (STX France): French shipbuilder and offshore substation integrator; ELO's first major offshore partnership for the Rentel project, and a directly adjacent peer in the offshore wind substation EPC value chain.
• Nexans: Global HV cable manufacturer and listed customer of ELO; overlapping in HV infrastructure projects (including offshore wind) though Nexans supplies cable while ELO installs it.
• Technique Solaire: French independent power producer developing solar PV plants, listed as a renewable-energy client of ELO; comparable end-market exposure (solar grid connections in France) rather than direct service-line competition.
• NKT: European high-voltage cable manufacturer and a stated client of ELO; comparable exposure to European HV grid build-out and offshore wind interconnections, sitting one tier upstream of ELO in the value chain.
