The National Electric Energy Agency (Aneel) revises the electricity tariff again on Friday, 28. In May, the regulatory agency changed the tariff flag to red at level 1, which meant an additional charge of R $ 4,169 for every 100 kilowatt hours consumed. The expectation is that the tariff will now reach the highest level, the red flag 2. If confirmed, the increase is already applied to consumers in the electricity bills of June.

Aneel explained that April, when the yellow tariff flag was in force, marked the end of the transition period between the wet and dry seasons in the main hydrographic basins of the National Interconnected System (SIN) for electricity. According to the regulatory agency, the wet period 2020-2021 recorded the worst water inflow in the reservoir of hydroelectric dams in the History of the SIN, measured since 1931. This scenario indicates the need to activate more thermal plants, which are more expensive.

A few weeks ago, a crisis in the supply of hydroelectric reservoirs in Brazil has triggered energy risk alerts for this year. The country, which has increasing pressure in the electricity generation sector, ended the rainy season in April with the lowest levels of reservoirs in the Southeast / Midwest region, the main one in terms of hydraulic power generation, for the month since 2015, when the country also faced a severe water crisis.

In view of the risk, the government, through the Electric Sector Monitoring Committee (CMSE), authorized that all available energy generation resources be used, no matter how much it will cost the consumer in early May. The definition involves activating all thermal plants and importing energy from Argentina or Uruguay.
