About Arevix
Built around flexibility.
Arevix Energy Consultoria em Energia Ltda. is an energy consulting and project development company focused on flexibility — helping generation and storage projects move from concept to contracted, bankable assets in Brazil's power market.
What We Do
Two branches, from wind turbines to grid-scale storage
Arevix operates across two related disciplines — advising on wind, grid, and storage technology, and developing battery storage assets of our own.
Energy Technology Consultancy
Independent technical and strategic advisory on grid control, ancillary services, and battery storage economics — drawing on 15+ years across wind, grid, and storage technology. Clients include RTDT; Julio has advised private investors on BESS projects since 2024.
BESS Project Development
End-to-end development of battery storage projects for the Brazilian market — from land and permitting through to construction-ready assets. Voltex, our platform for LRCAP 2026, is the first product of this branch.
