The level of the reservoirs of the hydroelectric plants that make up the SIN (National Interconnected System) reached 50% of storage, according to data released this Friday (27) by ONS (National Electric System Operator).
The advance reflects the intense rains that hit much of the country in recent days, bringing relief after the worst period of drought in recent history, according to INMET (National Institute of Meteorology).
With the start of the rainy season in November, hydroelectric reservoirs, which account for a large part of the electricity consumed in Brazil, began to recover.
According to the ONS, climate conditions have contributed to improving the country's energy security, especially in the Southeast and Central-West regions, which concentrate 70% of the electricity storage capacity.
During the year, the severe drought took the MME (Ministry of Mines and Energy) to adopt emergency measures to preserve reservoir levels.
In March, the CMSE (Electric System Monitoring Committee) restricted the flow of the Jupiá and Porto Primavera hydroelectric plants, located in the states of Mato Grosso do Sul and São Paulo, seeking to guarantee up to 11% of water in strategic reservoirs.
For Alexandre Silveira, Minister of Mines and Energy, the role of renewable sources during the dry period was also essential to avoid a greater crisis in the electricity sector.
“Brazil has broken records in wind and solar energy generation, and the use of these renewable sources has a direct impact on the positive results we have observed in the reservoirs,” he said.

An answer
Dear all, the obvious has been proven, with the unprecedented period of great drought, practically throughout Brazil, the importance of renewable sources such as wind and solar. Technically we know that, although there is intermittency of these sources, technically there are already exhaustive solutions to minimize it. Also regarding the infamous inversion of the flow of their generated energy. See the technologies of Zero Grid and energy storage via batteries, which are the very near future for renewable sources.
