With lower levels during the rainy season, the government orders the preservation of hydroelectric reservoirs

In March, water flow in rivers is expected to remain below the historical average for the rainy season, which is ongoing. ONS speaks of ‘point of attention’. The Minister of Mines and Energy, Alexandre Silveira, determined this Wednesday (6) measures to preserve the reservoirs of hydroelectric plants due to the reduction in water levels during the rainy season. The decision was taken at a meeting of the Electricity Sector Monitoring Committee (CMSE). For the minister, the measures are a way of preserving the country’s energy security, mainly in the Southeast and Central-West regions.

The monitoring group also authorized the retention of water in so-called “headwater plants” — located at the headwaters of rivers. According to Silveira, this measure can preserve around 11% of storage in the Paraná basin until August this year and around 7% in the Southeast and Central-West. The minister also ordered the portfolio secretaries and the ONS to adopt measures to preserve water in these headwater reservoirs, together with the National Water Agency (ANA) and Ibama.

According to the National Electric System Operator (ONS), the rainy season has been one of the most critical periods in the Southeast and Central-West regions. In February, the reservoirs had levels 12.4% lower than in the same period in 2023. The ONS projection is that, in March, river flows will continue to be below the historical average for the typically rainy period, which is ongoing . This scenario has been warned by the ONS as a “point of attention”. As hydroelectric plants account for around 47% of the energy generation capacity in the national system, the amount of water in reservoirs and the flow of rivers are important indicators.
