Greener Sees Brazil Adding 1.2 GWh of Battery Storage in 2026

• Brazil's battery market will add about 1.2 GWh in 2026, lifting the cumulative total above 2.5 GWh, Greener said.
• Commercial and industrial users take more than 500 MWh, almost half of the new volume.
• Brazil holds its first battery capacity auctions on Dec. 2 and Dec. 4, for supply from August 2028.

Brazil's battery storage market will take in about 1.2 GWh of new capacity in 2026, lifting the cumulative total above 2.5 GWh, consultancy Greener said in its 2027 strategic storage study. The company presented the report at a launch webinar on Nov. 5.

Commercial and industrial (C&I) customers account for more than 500 MWh, almost half of this year's new volume, according to the study. Homes add more than 200 MWh. Microgrids add more than 150 MWh.

The headline numbers come from a free preview on Greener's study page. The paid edition of the market research report carries projections of installed capacity, investment and CAPEX to 2031, along with chapters on regulation and business models. The preview gives no 2031 figure. It also does not say how much of the 2026 total is installed and how much is a forecast for the last weeks of the year.

Growth has been steep. Greener's previous edition counted 269 MWh installed in 2024 and 852 MWh in total by the middle of 2025.

The study in numbers

• 1.2 GWh of battery storage enters the Brazilian market in 2026, Greener said.
• 2.5 GWh or more is the cumulative total, so this year's volume makes up less than half of it (list.solar calculation).
• 500 MWh or more goes to C&I users, at least 42% of the 1.2 GWh (list.solar calculation); Greener calls it almost half.
• 4.5 times, roughly, is the 2026 volume against 269 MWh installed in 2024, using Greener's previous edition (list.solar calculation).
• 296,807 MW of capacity in 6,091 projects registered for Brazil's first battery auctions, the Energy Research Office (EPE) said.
• 120 MWh is the smallest project the auctions accept, 30 MW for four hours, or a tenth of Greener's 2026 national total (list.solar calculation).

Registration is not qualification. EPE said the eligible capacity will be known only after its technical review, so the 296,807 MW is a measure of interest, not of future builds.

The Ministry of Mines and Energy set two capacity reserve auctions for new grid-connected batteries. The first, for systems that meet local-content rules, runs on Dec. 2. The second, open to all projects, follows on Dec. 4. Winners sign 15-year contracts, with supply starting Aug. 1, 2028.
