ECSA

What ECSA does

ECSA Engenharia Socioambiental Sociedade Simples is a privately held Brazilian civil engineering consultancy founded in 1999 in Florianópolis, Santa Catarina, specializing in socio-environmental consulting for energy and infrastructure projects. The firm delivers three integrated service lines — Área Social (socioeconomic census, population resettlement, social monitoring), Área Patrimonial (land acquisition, valuation, indemnification), and Área Ambiental (EIA/RIMA/PBA licensing, environmental program implantation) — across the full project lifecycle from licensing through reservoir closure. ECSA has participated as socio-environmental and land acquisition consultant on Brazilian energy projects totaling over 23,000 MW of installed capacity, including marquee engagements on Belo Monte, Jirau, Teles Pires, Itá, and Campos Novos for clients such as Norte Energia, Tractebel Energia, Neoenergia, Iberdrola, EDF Brasil, Cemig, Furnas/Eletrobras, CPFL, Duke Energy, Vale, and Aura Minerals.

The company's underlying technology centers on a proprietary software platform named VALORIZA, which enables mass rural property valuation in accordance with ABNT-NBR-14.653 standards and is paired with a proprietary 'Caderno de Preços' unit-value handbook built across 20+ major infrastructure projects. ECSA's go-to-market is direct B2B sales-led, with project-based professional services contracts sourced through client relationships, reputation, and the company's website (ecsa-sc.com.br). Revenue is generated through per-project engagements for EIA/RIMA studies, land acquisition, population resettlement programs, environmental licensing support, and long-term social monitoring. The firm is founder-owned, with six co-founders all originating from the privatized Brazilian state utility GERASUL, providing 30+ years of accumulated institutional expertise in Brazil's complex environmental licensing and land acquisition regulatory framework.
