The rainy season, which began in October, will help strengthen the security of electricity supply across the country. This information was released by the CMSE (Electric Sector Monitoring Committee), which met this Wednesday (5) to assess the conditions of the system.

Even with the activation of the red tariff flag for the sixth consecutive month in November, the agency highlighted that the rains recorded in October have already favored the recovery of some Brazilian reservoirs. As a result, the average storage level of the power plants reached approximately 50% of total capacity at the end of the month.

Even with increased rainfall, the levels of ENA (Natural Inflow Energy) – the volume of water reaching the reservoirs – are still below the historical average in much of the country.

However, the forecast for the coming weeks indicates that rainfall should remain near or above average in the main river basins, which tends to improve the situation.

ANEEL Red flag remains in effect, and thermal power plants continue to operate despite renewable energy cuts.

CMSE also highlighted progress in new power generation and transmission projects, reporting that in October alone, 485 MW of capacity were added to the system, notably the Boa Sorte Solar Complex in Minas Gerais.

Furthermore, the Committee highlighted that the auctions held this year by ANEEL (The National Electric Energy Agency) is expected to mobilize more than R$ 5 billion in investments – a volume that, according to the agency, should guarantee access to energy in remote communities and strengthen the infrastructure of the electricity sector.

The CMSE (Brazilian National Monitoring Committee for the Electricity Sector) emphasized, through me during the meeting, that it will continue to monitor the system's behavior throughout the wet season to ensure that the energy supply remains stable across the country.

Point of attention

In the same week that the CMSE met to discuss the matter, EPE (Energy Research Company) released a study which draws attention to the importance of the country considering climate change in the planning of the electricity sector.

According to the survey, ignoring these variables can increase operational costs and raise the risk of supply shortages in Brazil, reinforcing the need to integrate climate and diversification of energy sources into a single energy security strategy.

Climate change imposes a new layer of uncertainty on Brazil's energy planning.
