When We Celebrate The 50th Anniversary Of The Ilha Solteira Hydroelectric Plant, We Are Also Celebrating A Historical Milestone In The Brazilian Energy Sector.
Founded in 1973, the plant continues to play a vital role in generating clean and sustainable energy for the country. To mark this important date, CTG Brasil, responsible for the management of the UHE Ilha Solteira, is leading an ambitious modernization project in the electric sector.
With a total investment of R$ 3 billion, this project encompasses the installation, replacement, and refurbishment of the 20 generating units at Ilha Solteira, as well as improvements to the 14 generating units of UHE Jupiá, which together form a hydroelectric complex of great importance for Brazil.
The Benefits Of Modernization
The main goal of this modernization program is to ensure increased availability and reliability of the plant’s operations, as well as to improve efficiency in energy generation for the coming decades. With investments estimated at R$ 228 million by 2023, CTG Brasil aims to deliver to Brazilian society new, modern facilities with a guaranteed lifespan for the next 30 years.
-
With 74% of companies facing difficulties in hiring, technicians and engineers in renewable energy are becoming scarce in Brazil and are essential to support the expansion of solar, wind, and green hydrogen projects.
-
The lack of welders, electricians, and operators becomes a structural threat in 2025, with the construction industry and manufacturing already suffering from delays, cost pressures, and labor shortages in Brazil.
-
Brazil and Paraguay are just 46 meters away from a historic union on the bioceanic bridge that promises to revolutionize trade between the Atlantic and the Pacific.
-
With 55 km over the sea, a cost of US$ 20 billion, and enough steel to build 60 Eiffel Towers, China’s largest project has connected Hong Kong, Zhuhai, and Macau in a colossal bridge that defies the logic of engineering.
New Generation Operation Center (COG)
As part of this modernization initiative, CTG Brasil recently inaugurated its new Generation Operation Center (COG) at UHE Ilha Solteira. This operations center is responsible for real-time monitoring of the company’s 12 hydroelectric plants and 2 small hydroelectric plants, totaling an impressive 70 generating units.
Thanks to the new COG, CTG Brasil has gained greater agility in decision-making, optimizing communication and ensuring maximum availability of its assets. Additionally, this structure also allows for the future incorporation of new assets and the adaptation of systems and teams to the new operational reality.
The Strategic Importance Of UHE Ilha Solteira
Located on the Paraná River, between the municipalities of Ilha Solteira (SP) and Selvíria (MS), the UHE Ilha Solteira has an installed capacity of 3,444 MW, contributing to the formation of the fourth largest hydroelectric complex in Brazil, together with UHE Jupiá.
With its dam measuring 5.6 km in length and a reservoir capable of storing 21 billion m³ of water, the plant plays a fundamental role in the operation of the Brazilian Electric System. Its numbers are impressive: 3.6 million m³ of concrete were used in the construction of the plant, enough to build 45 soccer stadiums the size of Maracanã. Moreover, the installed capacity of 3,444 MW and the generation of 10.05 million MW in 2022 allows for supplying, on average, a city of 3.4 million inhabitants.
The Clean Energy That Drives Brazil
The Ilha Solteira Hydroelectric Plant is a remarkable example of Brazil’s commitment to seeking clean and sustainable energy sources. Through the power of the waters of the Paraná River, the plant plays a key role in the country’s energy matrix, supplying electricity to millions of Brazilians.
Thanks to hydropower, Brazil reduces its dependence on fossil fuels, contributing to a cleaner and more sustainable environment. Additionally, hydropower generation is one of the most efficient forms of energy production, providing a constant and reliable supply to drive the country’s economic development.
