Our mission
Design and build safe, efficient and technically accountable electrical solutions, turning complex requirements into clear, documented and reliable deliveries.
Projects, reports and installation delivered with technical responsibility, safety and a complete view of the system.
Maccari Energia provides electrical design, distribution networks, industrial installations, technical reports, testing and construction support. We combine field experience, standards expertise and knowledge of utility requirements to reduce risk, rework and energization time.
The company began operating between August and September 2023. Since then, it has produced approximately 3,000 technical designs. A single construction contract may include 20 or more projects and supplementary details, such as SPDA, grounding, lighting, capacitor banks, protection, single-line diagrams and internal details.
Together with the three partners’ previous experience, the team has participated in more than 10,000 projects. We work throughout Brazil, with projects delivered in Rio Grande do Sul, Santa Catarina, Paraná, São Paulo, Mato Grosso do Sul and Minas Gerais.

A team of electrical engineers, occupational safety engineers and electrotechnical technicians, all with active professional registrations.
More than ten years of work in the electrical sector, with experience in substation maintenance, distribution networks, industrial installations, technical reports and construction support.
The team combines field practice, engineering calculations, regulatory compliance, and scope and schedule management. Some professionals have reviewed projects within a utility, adding the perspective of those who approve them: technical standards, submission procedures, inspections and the details that prevent rejection and delays.
From survey to commissioning, every stage has a qualified technical professional, with the appropriate ART or TRT duly filed.
