The auction scheduled to take place in April 2026 should boost investments and strengthen the electricity system
Brazil is preparing to hold, in April 2026, its first auction of grid-scale battery storage systems, an initiative that marks the country’s entry into a market with billionaire potential.
The event will follow the reserve capacity model (LRCAP), with contracting projects from 30 MW and contracts of about 10 years. The batteries will be remunerated by the availability of power, acting at critical moments, such as peaks in demand and fluctuations in renewable generation.

The expectation is to contract between 2 GW and 3 GW, with the potential to move around R$ 10 billion in the first rounds. The government has been articulating the attraction of international investments, targeting global companies in the sector.
The measure responds to the advance of solar and wind sources, which have increased the variability of the electrical system. In this context, batteries emerge as an alternative to thermal plants, offering a quick response and greater predictability.
In addition to reinforcing energy security, the auction can boost the creation of a battery production chain in the country, with repercussions The initiative aligns Brazil with markets where large-scale storage is already a key part of the energy transition.
