The growing demand for electricity in Brazil—driven by new industrial developments, urban expansion, and distributed generation—puts pressure on the electrical system to become increasingly flexible, resilient, and efficient. In this scenario, substation infrastructure—a central point between generation, transmission, and distribution—must keep pace with this movement, with solutions that address both the construction of new facilities and the modernization of existing ones.
At BR INFRA, we deliver complete solutions for substations—both in turn-key projects, also known as greenfield, and in the modernization of existing infrastructure, known as retrofit or brownfield. In either approach, our commitment is to deliver robust, safe electrical infrastructure, prepared for the challenges of today’s and tomorrow’s electrical system.
Turn-key: from foundations to energization
In the turn-key model, BR INFRA assumes full responsibility for implementing the substation. This includes engineering, the supply of 100% of materials and equipment, and full execution of the work, from civil to electromechanical.
For the client, this means predictability, fewer interfaces, optimized timelines, and a solution with guaranteed performance. At the end of the process, we hand over the key: the substation is ready to operate reliably from day one.
Retrofit: upgrading to keep delivering energy safely
Retrofits, in turn, are solutions applied to existing substations. They are interventions aimed at modernizing, expanding, or adapting assets to new operational requirements—whether due to obsolescence, increased load, or regulatory and safety requirements.
In practice, it is surgical engineering: it requires technical mastery, detailed planning, and execution that respects the facility’s continuous operation.
Real example: Campos Substation
BR INFRA is currently working on the modernization of the Campos Substation, carried out in two stages. The first stage, corresponding to SE Campos 22R, includes the replacement of phases A and B of the 345 kV reactor bank. The second stage, SE Campos 7OP, corresponds to the replacement of 345 kV disconnect switches. Both stages of the contracted scope include management, development of detailed design, supply of materials, equipment and SPCS (Protection, Control and Supervision System) services, execution of the works, commissioning and energization, in accordance with the technical specifications established by Eletrobras.
This is the engineering that ensures continuity of the region’s electricity supply, with safe and sustainable progress.
Technical expertise, responsibility, and a future-focused vision
At BR INFRA, we know that each project requires a tailored response. That is why our focus is on deeply understanding the client’s needs, assessing the asset’s technical reality, and proposing solutions that deliver real value, with excellence in execution.
Because building infrastructure is more than construction: it is anticipating scenarios, solving complex problems, and sustaining growth with intelligence and responsibility.
