Relief on the way?: Parana’s flow expected to improve as Interlude Dam opens its floodgates

The Itaipu Binational Dam on the Parana River reopens one of the hydroelectric dam’s drains To reduce water levels after heavy rains in Brazil. They estimate that this condition will bring some relief to the river In the next few days it will increase its flow in Argentine territory.

According to a statement issued by the company on Friday, it has been decided to reopen the closed gate after almost a year and a half. “Storage Conditions of Headwater Reservoirs for Hydropower”.

Southern Brazil has been experiencing heavy rains since November, and this situation necessitates action “considering that there was a recovery after the water in the levels of the main reservoirs of the Brazilian Interconnected System (SIN-BR)”. 2021 2022 crisis, reaching 65.8%”.

“This significant increase in storage volume is particularly due to the rainfall recorded in most of Brazil since the end of November,” the binational company said in a statement.

The discharges were coordinated by the Itaipu operational monitoring and the national operator of the Brazilian electricity system, and as a result, will limit the reservoir volume and contribute to the improvement of the navigation conditions of the Paraná River, mainly from the confluence. Along the Paraguay River.
