The State confirms that the interruption of production of the hydroelectric plant, due to the arrival of sludge, will not cause losses to the NAS
The closure of the Retiro Baixo plant (82 MW – MG), due to the rupture of Vale dam in Brumadinho was confirmed for Tuesday, January 29, according to the determination of the national operator of the electrical system. According to Furnas Centrais Elétricas, which operates the hydroelectric power plant alongside Cemig, the interruption of the operation "aims to protect the equipment" and will not harm the power supply of the system national interconnected. In addition to crippling the company's operations, companies will conduct maneuvers to close the water intakes.
According to a press release issued Monday afternoon (27), the state generator indicates that: for the moment, it is not yet possible to determine the impacts that the arrival Sludge from tailings will have from the point of view of operational procedures of the factory. The work, according to the statement, aims to protect the safety of the surrounding population, the local environment and hydroelectric equipment. "The Low Energy Retreat badesses the movement and density of the sludge that goes to the plant and there is no structural risk to the dam," said Furnas.
The thick mud that moves along the Paraopeba River basin can extend, in the energy field, beyond the HPP Retiro Baixo. If this occurs, the tailings volume would also reach the Três Marias (396 MW – MG) plant, operated by Cemig. In this way, the mud would reach the São Francisco River. Chesf, the operator of hydroelectric power plants located in the northeastern part of the main river basin of the region, is closely monitoring the evolution of the case. Preventive actions, such as water quality control at various points in São Francisco, have already been undertaken by the company in conjunction with the National Water Agency.
"We expect that the mud will not exceed the Três Marias hydroelectric plant, if it exceeds the structure of the Retiro Baixo plant.At the moment, you can not be sure what will happen because it is expected that these tailings will reach Retiro Baixo from next weekend, "said Chesf President Fábio Lopes. The latest news bulletin issued by the Geological Survey of Brazil, which is ahead of the government's monitoring work, indicates that the mud will be in Retiro Baixo from 5 to 10 February and will reach Três Marias around ten days later
