Better developing battery systems to store renewable energy would support Brazil's power generation capacity and help it reach its supply potential, panelists at a climate summit in Sao Paulo, Brazil, said today.
Battery energy storage systems (Bess) could help in regulating renewable energy generation when it exceeds demand, power company Comerc Energia's chief executive Clarissa Sadock said. Brazil has an abundance of renewable energy sources, including hydropower and wind.
Hydroelectric and distributed generation account for more than half of Brazil's power matrix, at 41pc and 18pc, respectively. Wind sources represent 15pc, while thermal, solar and biomass contribute with less than 10pc each, according to grid operatorONS.
Some major agricultural producers have adopted battery systems to store electricity and distribute it to large farms in more remote area, Sadock said, adding that installing Bess is less expensive than building a transmission line to these rural sites. But overall Brazil's Bess system development has been modest.
Battery systems would be a solution for power flexibility with controllable energy sources — such as renewables — to promptly meet demand and regulate supply, especially during peak hours. They can also balance peak capacity in Brazil's electric grid, adjust quality and enable digital solutions.
Brazil's installed power capacity will increase by 36GW to reach 268GW by 2029, mainly driven by growth in renewable sources, according to ONS' 2025-29 power operations plan.
