What Dois A Engenharia does
Dois A Engenharia is a privately held Brazilian civil construction and engineering company founded in 1999 and headquartered in Natal, Rio Grande do Norte. The company operates three business units: Engenharia, which executes EPC contracts for wind farms, solar plants, and sanitation infrastructure; Towers & Service, which constructs pre-fabricated concrete wind turbine towers above 120 meters and provides specialized blade inspection, waterjet demolition, and maintenance services; and Incorporações, a real estate development subsidiary. Dois A reports having executed more than 150 wind parks, 8+ GW of installed wind capacity through its projects, 2,300+ turbine foundations, and 1,400+ km of access roads, and claims approximately 25% market share in Brazil's wind farm infrastructure construction segment.
The underlying technology centers on civil construction and electromechanical assembly, with proprietary capability in pre-fabricated concrete tower construction at heights above 120m, ultra-high-pressure waterjet concrete demolition at 2,500 bar, and the Panoblade HD imaging inspection system. The company operates its own pre-fabricated concrete tower factories, enabling vertical integration on the tower segment. Customer relationships are enterprise-driven and project-based, with named counterparties including ENEL, Neoenergia, Voltália, EDF, AES Tietê, COPEL, Casa dos Ventos, CTG, Auren, Echoenergia, Essentia, and government utility CAERN. Revenue is generated through one-time EPC contracts (wind, solar, sanitation) and through professional-services contracts for wind turbine O&M, with project-based pricing awarded via competitive bids and direct commercial engagement rather than disclosed list pricing.
The company's business model is sales-led and field-based, with no self-serve, PLG, or marketplace channels. Marketing is primarily B2B, anchored on a project case-study portfolio on doisa.com, supplemented by a corporate Facebook presence, Great Place to Work certification for five consecutive years, and a lifestyle-oriented blog supporting the Incorporações real estate brand. Geographic operations span the Brazilian states of Rio Grande do Norte, Paraíba, Bahia, Piauí, Pernambuco, and Goiás, with no disclosed international footprint. Ownership is privately held with no disclosed parent, institutional investor, or cap table information.

Dois A Engenharia competitors and assessment
Company assessmentOthers
- Casa dos Ventos: Brazil's largest wind energy developer and a known Dois A customer; not a direct EPC peer, but the most relevant downstream counterpart and a useful proxy for pipeline demand.
- Vestas: Global wind turbine OEM; adjacent rather than directly comparable, but partners with and sells through EPC contractors like Dois A, and could choose to insource more construction activity over time.
Direct peers
- Elecnor: Spanish infrastructure and renewable energy EPC contractor with active wind and solar farm construction in Brazil and Latin America; closely comparable business model to Dois A's engineering division.
- TSK: Spanish EPC contractor specializing in solar PV, wind, and electrical infrastructure projects globally, including Latin America; comparable renewable EPC scope and project-based revenue model.
- Serveng: Brazilian civil construction and infrastructure firm active in energy projects; competes with Dois A on large civil works, foundations, and access road construction for renewable energy developers in Brazil.
- Galvão Engenharia: Brazilian infrastructure construction company executing energy, sanitation, and industrial projects; comparable portfolio of civil works, government contracts, and energy infrastructure.
- Acciona (Infrastructure / Energía): Global renewable energy EPC and infrastructure developer with significant wind farm construction activities in Latin America; competes with Dois A on utility-scale wind project execution and shares a similar EPC-plus-O&M operating model.
Broad incumbents
- Andritz: Global supplier and EPC contractor for hydroelectric and wind power plants; comparable equipment and service offering for renewable energy developers, with established presence in Brazil.
- Construtora Norberto Odebrecht: Large Brazilian engineering and construction conglomerate historically executing energy, sanitation, and infrastructure projects across Latin America; broader and more diversified than Dois A but overlapping on wind EPC and sanitation.
- Engie Brasil: Major Brazilian energy utility and renewable IPP; overlaps with Dois A as both a customer-class entity commissioning wind/solar projects and as a competitor for in-house EPC execution.
