Sao Paulo, Sep 19 (EFE) .- A failure in a substation left dozens of municipalities in the southeastern region of Brazil without power for about an hour on Saturday night, the national electricity operator reported on Sunday, ruling out that the episode is related to the severe drought in the country.
The utility Furnas, a subsidiary of the state group Eletrobras, which is in the process of privatization, said in a note that there was “a failure” in its Rocha Leao substation, located in Rio de Janeiro, “around 9:21 pm local time” on Saturday. (00.21 GMT on Sunday).
At least 62 municipalities in Minas Gerais and another 13 in Rio de Janeiro, two of the three most populous states in Brazil, suffered a blackout that lasted for about an hour until the total restoration of service, according to the concession companies.
“The protections acted correctly to isolate the fault, causing the shutdown of all the equipment,” said Furnas, which operates in the generation and transmission segments.
After the incident, “Furnas’s technical team promptly began the procedures to restore supply to the distributor,” he added.
The causes of this general drop in energy are still unknown and will be the subject of an investigation by the responsible bodies.
For its part, the National Electric System Operator (ONS) reported this Sunday that it will “evaluate” what happened, although it stressed that “it is not related to the water crisis” that the country is going through, the worst in the last 91 years, according to estimates. officers.
The severe drought affects mainly the southeast and central-west of Brazil and has caused the reservoirs that supply the hydroelectric plants in these two regions to be at the lowest levels in the last two decades.
In this context, a recent report by the Union Court of Accounts leaked by the G1 portal warned that the measures adopted by the Government in relation to the water crisis are, so far, insufficient to avoid energy rationing in the coming months .
