One of the Largest Hydroelectric Plants in the Country Is About to Go Into Operation: With 95% of Its Works Completed, the UHE São Roque, in Santa Catarina, Will Have the Capacity to Supply 4 Municipalities in the State.
São Roque Energética announced, on Monday (25), that one of the largest hydroelectric plants in Santa Catarina is in its final construction phase. The unit, which is already 95% complete, is named UHE São Roque, in the Southern Plateau of the State, and is only waiting for authorization from the Environmental Institute of Santa Catarina (IMA) to begin filling the water reservoir. According to the agency, this is expected to happen later this week. Therefore, the expectation is to close the reservoir to start filling it in the coming days, making it possible for São Roque to begin generating and supplying energy to the ONS by the end of next month.
Hydroelectric Plant in Santa Catarina Is One of the Largest in Brazil
The deadline was brought forward at the request of the National Electric Energy Agency (Aneel) and due to the recent energy crisis Brazil faced. When completed, the flow rate of the hydroelectric plant will be approximately 33 m³/s.
The unit will be able to produce 141.9 MW, which is equivalent to the consumption of households in the four largest cities in Santa Catarina: Florianópolis, Chapecó, Joinville, and Blumenau. The project is considered the largest hydroelectric plant under construction not only in the state but in the entire country, according to the entity responsible for UHE São Roque, São Roque Energética.

The largest hydroelectric plant will be located on the Canoas River, between the municipalities of São José do Cerrito and Vargem. However, the reservoir also encompasses Brunópolis, Frei Rogério, and Curitibanos, while the transmission line, which will distribute the renewable energy generated by the three turbines to the connection with the SIN, passes through Abdon Batista.
The Largest Hydroelectric Plant in the Country Received R$ 1.1 Billion in Investments
One of the main differences of the largest hydroelectric plant in SC is the regulating reservoir, which means it can store water for dry periods, similar to what happens in large projects in other states.
The pace of construction was slowed in 2016 when the plant in Santa Catarina was already 80% structurally completed. Only conservation and maintenance activities were maintained. The total amount invested is R$ 1.1 billion, and construction resumed in July of last year.
According to the project coordinator of the São Roque Plant, Ênio Schneider, the new estimated cost for completing the remaining 5% of the works in Santa Catarina is R$350 to R$400 million. This amount is allocated to the set of activities, for both the hydroelectric plant’s works and the transmission line, as well as social and environmental issues, including compensation for properties. It is worth noting that the state participates in the financing package through the Regional Development Bank of Southern Brazil (BRDE), with R$ 140 million.
MME Recognizes the Importance of the Hydroelectric Plant in SC
In an email sent by the MME to the IMA, the unit was reinforced as essential and a major highlight because it is a headwater plant, making it possible to regulate all existing plants downstream and, considering it will be a storage reservoir, it will play an essential role in water storage.
Because in addition to the 142 MW generated by one of the largest plants in the country, the structure has a reservoir that will further expand generation in other plants below it, such as the Garibaldi plants, located in Abdon Batista and Campos Novos, between the municipalities of Celso Ramos and Campos Novos.
