El Niño could drive PV generation curtailment to 40% in Brazil in 2026
A strong El Niño in late 2026 could push renewable generation curtailment in Brazil to 25%, with solar PV curtailment potentially reaching 40%. Additional thermal dispatch could further increase PV curtailment to 47%, raising financial risks for renewable projects.

Brazil’s distributed solar fleet achieves 72% average performance ratio
A study presented by Brazil’s grid operator ONS shows that distributed-generation solar PV plants achieve an average performance ratio of 72%, with variations driven by seasonality and soiling. The findings will support new forecasting models to improve grid management as distributed solar capacity continues to expand.

Smart controllers help Brazilian PV projects bypass reverse power flow constraints
Brazilian solar installer Alba Energia is using smart power controllers combined with Aneel’s simultaneity rules to overcome reverse power flow restrictions and enable larger distributed solar arrays. The approach allows PV system owners to maximize on-site solar generation while keeping grid exports within utility-approved limits.
China could produce more batteries than global demand by 2030, says US think tank
China’s battery cell manufacturing capacity could exceed projected global demand by 2030, according to a new Carnegie Endowment report, which recommends selective cooperation with Chinese companies to reduce supply chain risks.
Brazil distributed solar financing rises as utility-scale investment falls
Brazil’s renewable energy financing rose to BRL 36.3 billion in 2025 but remained well below the 2022 peak, as high interest rates, curtailment, and regulatory uncertainty continued to constrain investment. Distributed solar proved the most resilient segment, while wind power rebounded strongly and energy storage emerged as a growing market despite financing figures that likely understate its expansion.

Brazil falls short of its battery storage potential
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.
