What Jacquel and Chatillon Design Office does

Bureau d'études JACQUEL & CHATILLON is a privately held French environmental engineering consultancy (bureau d'études) providing integrated permitting, technical, and stakeholder-engagement studies for renewable energy and infrastructure projects. The firm operates four regional agencies — La Vôge-les-Bains (Vosges, headquarters), Gondreville (Lorraine), Châlons-en-Champagne (Marne), and Valence (Drôme, opened 2022) — and is co-led by co-gérants Bruno Chatillon and Laurent Jacquel with agency directors Thomas Dubanchet and Romain Avisse. Co-founders' practices trace back to 1988 (Chatillon, hydroelectric at T.H.E.E.) and 1990 (Jacquel, hydraulic), with formal merger in 2002.

The firm delivers seven service lines: hydraulics and Water Law dossiers, hydroelectric feasibility and ecological continuity, wind energy (ICPE authorization, landscape, photomontages, public consultation), photovoltaics and agrivoltaics (feasibility, agricultural impact, permitting), landscape integration studies (3D modeling, ZVI mapping), ecology (biodiversity inventories, ecological continuity, river renaturation), and mediation/public participation. Core technology is a stack of numerical hydraulic modeling, 3D landscape visualization tools, ecological field-survey methods, and standardized ICPE/Water Law regulatory dossier templates; the company reports over 400 wind projects with 4 TW developed (1.5 TW granted), 100+ photovoltaic projects at 500+ MW, several hundred hydroelectric studies, and 200+ Vosges-region hydraulic studies as an accumulated reference base.

Revenue is generated through project-based professional services fees, quoted per engagement under multi-year contracts, with no subscription or recurring component. Go-to-market is direct, regional agency-led sales targeting enterprise clients in renewable energy (TotalEnergies, RWE, Engie Green, EDF Renewables, SSE, Enercon, VSB, Boralex, BayWa, Valeco, Qair and others), municipalities, and real estate developers requiring Water Law compliance. The firm operates with approximately 30 engineers and technicians organized into Environment, Landscape, and Ecology poles, supplemented by external specialists in acoustics, ornithology, and chartered surveying for full ICPE dossier delivery.
