This weekend, the reservoirs of the SIN (National Interconnected System) hydroelectric plants reached the 70% capacity mark, a volume 7% higher than that recorded in the same period in 2024.
The percentage was already expected by the ONS (National Electric System Operator), as report published by Canal Solar earlier this month.
According to the agency, the levels considered high of stored energy are directly related to the rainy season, which since November 2024 has shown volumes above the historical average.
This scenario provided relief for the reservoirs, which are responsible for guaranteeing a large part of the electricity consumed in the country.
Furthermore, the Operator highlighted that some policies adopted by the CMSE (Electric System Monitoring Committee) also contributed to the recovery of water levels.
Among the measures is the restriction of the outflow of the reservoirs of the Jupiá (MS) and Porto Primavera (SP) plants, which allowed the retention of up to 11% of water in the reservoirs of the Southeast and Central-West regions, which concentrate 70% of Brazil's energy storage capacity.
In 2024, it was determined that strategies would be adopted to preserve reservoirs in the North region, which were facing a serious water crisis. The highlight was the Xingu River basin, whose scarcity situation was officially recognized by the National Water Agency (ANA) that year.
Given the increase in stored volume, there is an expectation that the green tariff flag will be maintained in March, which indicates favorable conditions for energy generation.
As a result, consumers will once again not be charged extra on their electricity bills, as the reservoirs are at safe levels and there is no need for incentives to reduce energy consumption.
