Brazilian grid operator expects PV, wind curtailment to reach 40 GW
Brazil’s ONS warns that wind and solar curtailment could reach 40 GW annually by 2030 as renewable expansion outpaces demand growth and grid flexibility. The operator highlights transmission upgrades, storage, demand response, and better management of distributed generation as key measures to maintain system reliability.

Brazil’s FIFA World Cup match could cut energy demand by up to 20%, local PV sector calls for greater system flexibility
Brazilian grid operator ONS forecasts a sharp drop in consumption during the Round of 16 match and is reinforcing operations to ensure grid stability. According to PV association ABSolar, the challenge lies not in a lack of information, but in the need to adapt the electrical system to an increasingly renewable energy mix.

Free market, curtailment, and storage reshaping Brazilian solar sector
Brazil’s solar sector is entering a new phase marked by curtailment, grid constraints, and regulatory shifts, with growth increasingly tied to new business models and market dynamics. Industry leaders say storage will be central to this transition, enabling system integration, mitigating risks, and unlocking future demand.
New PV inverter efficiency metric reflects local solar conditions
Researchers in Brazil have developed a weighted PV inverter efficiency methodology that accounts for country-specific solar irradiance and operating conditions. The approach is designed to address the limitations of international metrics by incorporating variables such as input voltage and maximum power point tracking (MPPT) performance.
Brazil curtails 20% of solar and wind output in 2025, with losses at $1.2 billion
Brazil curtailed about one-fifth of its solar and wind generation in 2025, wasting an estimated BRL 6.5 billion ($1.23 billion), as grid constraints and demand mismatches pushed the power system close to operational safety limits on 16 days, according to a report from Volt Robotics.
