In an interview in Economy & Sustainability magazine, Marcio Rea, Director-General of Brazil’s ONS and GO15 2026 Vice President, discusses how decentralization, digitalization, and energy storage/AI are reshaping Brazil’s power grid. With more than 90% of renewable energy in its energy mix, including nearly 30% from wind and solar, Brazil aims to lead the way towards a clean energy transition.
Key technical insights from Mr. Rea focus on the following points :
- Hydroelectric plants (43.8% of capacity) remain vital for balancing renewables.
- Batteries (BESS) are critical for managing solar peaks and nighttime demand.
- Decentralization, digital tools, and global collaboration, especially within GO15, are key to prepare the future of power grids.
