Coherence Energies

What Coherence Energies does

Coherence Energies is a privately held French engineering consultancy headquartered in Pérenchies (Hauts-de-France), founded in 2008 and operating through a second antenna in Saint-Malo (Brittany). The firm delivers independent, end-to-end technical assistance for territorial energy transition, organized around two service poles: renewable energy (photovoltaic project management AMO/MOE, wind project assistance, feasibility studies, and operational asset monitoring) and building energy efficiency (audits, dynamic thermal simulation, design assistance for new and renovated buildings, and energy savings action plans). It holds Opqibi engineering qualification and serves municipalities, intermunicipal communities (EPCI), departments, public institutions, industrial and commercial enterprises, citizen cooperatives, and social housing providers, with a strong emphasis on independent advice free of energy-supplier affiliation.

The company's strategic differentiator is its pioneering position in collective self-consumption (ACC) in France since 2018. Through its dedicated sub-brand 'Passeurs d'Énergie' (created 2022), Coherence Energies designs, deploys, and manages ACC operations — including the legal Personne Morale Organisatrice (PMO) role, participant management, energy allocation, producer-consumer billing, and ENEDIS API-based monitoring. Notable operational firsts include the first ACC operation in Hauts-de-France (2018, Communauté de Communes du Haut-Pays du Montreuillois), the first HTA consumer in an active ACC operation in France (Conseil Départemental du Pas-de-Calais), the first 20 km perimeter derogation, and the 'Energie Collective Pérenchies' — one of France's first open ACC schemes integrating enterprises and individuals. By mid-2023 the firm held approximately 15% of France's installed ACC capacity (1.8 MWc), growing to 3+ MWc in service by 2024 with dozens of additional operations in development.

Revenue is generated primarily through project-based engineering fees (AMO/MOE, energy audits, feasibility studies) billed to public and private clients on a per-project basis, supplemented by recurring managed-services revenue from Passeurs d'Énergie ACC operations. The firm has completed more than 300 renewable energy operations totaling approximately 30 MWc across rooftop, ground-mounted, and canopy PV, alongside 20+ years of wind project experience with 500 MW carried to completion. Customer acquisition runs through direct engagement, public procurement, and partnerships with regional energy-transition bodies (CD2E, B2E Bretagne, Bpifrance, ENEDIS, citizen cooperatives such as CIREN). The firm remains small (1–10 employees) and privately funded, with no disclosed external capital raises.

Revenue model

1. Engineering & Technical Consulting Services: Cohérence Energies generates revenue primarily through fees for engineering and technical assistance services. These include energy audits, feasibility studies, project management (Assistance à Maîtrise d'Ouvrage - AMO), and full maîtrise d'œuvre (MOE) services for renewable energy installations and building energy efficiency projects. Revenue is project-based and likely structured as fixed-fee contracts or time-and-materials engagements with public and private sector clients.
2. Collective Self-Consumption (ACC) Management Services: Through the Passeurs d'Énergie brand, the company provides ongoing management services for ACC operations including PMO delegation, participant management, energy allocation and billing, production monitoring, and digital platform access. Revenue derives from service fees charged to ACC operators (collectivities, social housing providers, citizen cooperatives).
