Critical safety faults found in one in eight BESS at factory stage
More than one in eight battery storage systems failed critical safety checks at the manufacturing stage in 2025, with the bulk of defects found not in cells but in the balance-of-system components and enclosures that hold them together, according to Intertek CEA.
Brazil falls short of its battery storage potential, expected to reach 1 GW in 2026
The Brazilian Association of Energy Storage Solutions gathered executives to debate applications that could solve systemic challenges facing the Brazilian electricity sector. The issue, they argue, goes beyond a "BESS vs. thermal or renewables vs. energy security" debate, but involves finding the best combination of security, price, 'renewability', and flexibility.

Brazil increases import tax on batteries at local manufacturer’s request
The measure raises the import tariff from 18% to 25% for 48V LFP batteries intended for stationary applications in telecommunications and photovoltaic systems of up to 4.8 kW until May 2027, following a request from the domestic industry via LETEC. For other batteries classified as lithium-ion electric accumulators, the reduced rate of 18% remains.
Brazil’s battery capacity auction risks being delayed until 2027
The competition still lacks a policy framework and must take place five to six months after its publication. Brazil's storage association warns of a need for additional power starting in 2028, with a growing risk of a deficit. The battery LRCAP has been expected since 2024.
Brazil can reach 7 GW in storage by 2035
Projections from the Energy Research Company (EPE), shared during the Absolar Storage Leaders event, depend on a stable legal framework and regulatory progress. Authorities and stakeholders in the electricity sector highlight the role of batteries in reducing costs, ensuring energy security, and expanding renewable energy.
