With the worst drought in nine decades, hydroelectric reservoirs are at a critical level and threaten the system’s operation
Threats of blackouts and water rationing should continue until the end of 2021 and actions against waste should be reinforced. The voluntary reduction and increase in tariff flags can help to ease the water crisis. With the worst drought in nine decades, hydroelectric reservoirs are at a critical level and threaten the system’s operation. For the professor at the UFRJ School of Engineering, Maurício Tomasquim, the thermoelectric plants should have been activated before. “Since November, everyone knew that the reservoirs were going down and that the hydrology was very bad. The thermoelectric plants did not work at full capacity. But the most surprising thing is that in February, practically with the wet season well under way, the generation of thermoelectric plants decreased even more”, points out the professor. The Superintendent of Inspection of the National Electric Energy Agency (ring), Gentil Nogueira, assesses that the emergency works will help maintain the supply.
“In 2014 and 2015 it was different. We had to take energy from the Southeast to the Northeast, but today we are bringing energy from the Northeast. We are also anticipating works. Aneel issued an authorizing resolution to subsidize the works to reinforce systems that would expand the exchange and reduce any restriction on generation in the system. It is the authorized resolution of 10.398/2021. We are organizing with the country’s distributors to make this, from a practical point of view, operational for all consumers, so that they can understand, make their consumption reduction choices and contribute to the current scenario we are facing”, he suggests Walnut. The president of Instituto Trata Brasil, Edson Carlos, points out that the country should urgently invest in reducing water loss. “If Brazil had water loss patterns like we have in developed countries, around 10% to 15%, the reservoirs would certainly be fuller. But Brazil has an average loss of 39% and almost 30% in the metropolitan region of São Paulo. So, at the same time that citizens need to use water better, we need to quickly combat water and sewage companies, leaks, theft and water meters that do not mark anything right. It’s a process”, he says. The president of Trata Brasil highlights that the works carried out during the 2014 water crisis can help in the current phase. The government points out that the measure of rewarding those who reduce energy use by 10% will benefit the people who consume the most.
