Energy infrastructure · EPC · Storage
Engineering and construction of substations, grid connection, solar generation and battery storage. More than 450 MW built in Brazil.
Figures reflect projects delivered by the One Energy Group.
Why we exist
Brazil has abundant renewable generation and a grid that cannot always move it. In the first four months of 2026 the country curtailed 2,843 average MW of solar and wind — 17.2% of what those plants could have produced, and 2,233 MW of that in the Northeast alone.
That is the paradox foreign investors meet: energy is cheap and plentiful, and connecting to it is the hard part. Grid access queues, substation works, licensing and local contracting are where schedules slip.
We are the company that builds that part. Substations, connection, civil works, electrical assembly and commissioning — with our own crews, in Brazil.
Who we work with
Site prospecting, energy feasibility, substation and connection, on-site generation and storage. Brazil's incentive regime pushes 40% of qualifying investment into the North, Northeast and Centre-West — where we already build.
Local engineering, tropicalisation, installation, commissioning and after-sales for manufacturers entering Brazil. Under 200 MW of storage is installed in the country today, against 8–15 GW projected by 2030.
