Brazil BESS sales hit 504 MWh in Q1 as market accelerates

Market intelligence firm Greener said Brazilian companies purchased 504 MWh of BESS in the first quarter of 2026, bringing cumulative sales in the country to 1.9 GWh.

The figures were presented by Greener during the first day of the Greener Summit 2026. The company said BESS sales increased by 36% in the first quarter of 2026 compared with the cumulative volume recorded through the end of 2025.

Greener identified strong growth in Brazil’s storage market from 2025, when manufacturers and solution providers received orders totaling 730 MWh. The volume was equivalent to the cumulative sales recorded during the previous five years.

The estimated volumes represent contracted sales by manufacturers and service providers rather than installed capacity.

Greener said falling battery costs have been a major factor behind market growth. Based on a 500 kW system with 1,000 kWh of storage capacity, the capital expenditure (capex) declined from BRL 3.97 ($0.78)/Wh in 2020 to BRL 1.88/Wh in 2025, a 53% reduction. Greener expects costs to fall further to BRL 1.73/Wh in 2026 and BRL 1.34/Wh by 2030.

The company also identified increasing clarity around business models and customer needs as a driver for adoption. Backup power applications are gaining interest among households, agricultural businesses, commercial users, and industries seeking protection against outages.

Peak shaving applications are being adopted by customers seeking to avoid exceeding contracted demand levels during periods of high consumption. Load shifting is also gaining traction among consumers exposed to different electricity tariffs throughout the day, allowing them to charge batteries during lower-cost periods and use stored energy during more expensive periods.

Greener highlighted the growth of “energy storage as a service,” or “BESS-as-a-service,” as a model helping accelerate storage adoption in Brazil. Under this structure, the provider funds the initial investment while customers pay a recurring fee for system availability and energy services.

The company said contracts can include fixed availability payments, usage-based fees, shared savings from peak shaving or load shifting, guaranteed electricity bill discounts, or hybrid structures combining fixed and variable payments.
