In Bahia, northeastern Brazil, WEG has been contracted to supply major electrical infrastructure for the UFV Irecê Phase 1 solar project, which will have an installed capacity of 161 MWp.

The company is providing a three-phase step-up transformer rated at 160 MVA (34.5/138 kV) to connect the plant to Brazil's National Interconnected System (SIN). The transformer has been installed at the Uberlândia 138 kV collector/step-up substation in João Dourado and at the 138 kV connection bay of the Irecê CHESF Substation.

A key technological feature of the transformer is the inclusion of two merging units that digitize all analog and digital signals, replacing traditional control cables with optical fiber. This setup allows faster implementation, lower cabling costs, easier future expansions, and more reliable system monitoring.

In addition to the transformer, WEG is supplying all yard equipment for the substations, including disconnect switches, potential and current transformers, surge arresters, protection and control systems, as well as engineering and commissioning services.

The solar complex is being developed by a joint venture of Illian Energias Renováveis (part of the Electra Group), Acelen, and Perfin Infra. The project is expected to reduce approximately 128,000 tons of CO₂ per year and create more than 500 jobs during the construction phase.

By providing this equipment and services, WEG is helping step up the voltage generated by the plant to transmission levels, ensuring efficiency, stability, and reliability in delivering renewable energy to the national grid.
