Amphibious Turbogenerators (TGAs)
Technology developed by HIGRA is a source of clean and renewable electricity generation. With efficiency and sustainability, the TGA can be used submerged or not, replacing reducing valves and taking advantage of the hydraulic potential of waterfalls for generation and recovery in dam spillways. Its versatility of installation expands the possibilities of applications, making it a flexible and effective solution for sustainable energy production.

Concept and Characteristics
The HIGRA Amphibious Turbogenerator (TGA) is an integrated power generation system that can be used, submerged or not, to replace reduction valves, use waterfalls to generate energy and also to recover energy from dam spillways. With satisfactory performance, the equipment automates pressure in distribution networks via remote control.
The TGA is a completely integrated piece of equipment, including an electric generator and turbine. The electric generator is of the submerged wet type and is cooled by the fluid passing through the machine, providing excellent performance. The turbine is designed according to the operating conditions of the application, using CFD tools to optimize the geometry and achieve high efficiency.

Case: HIGRA generates electricity from flowing water in Santa Catarina
A pioneering project in the state, in partnership with Companhia Águas de Joinville, it guarantees clean and sustainable electricity for the city’s population, as well as economic benefits.
Production can reach 40 kWh, corresponding to 28,800 kWh per month, enough to supply the consumption of around 100 homes. The energy generated is injected into Celesc’s network and the company receives credits, resulting in annual savings of R$ 300,000.
The project is an example of how the innovation and technology of HIGRA products promote sustainability and energy efficiency.
"This is a major innovation for the city of Joinville. It's the first hydroelectric plant installed in the state of Santa Catarina in the middle of a water pipe. In practice, we are generating energy with water that was already flowing through this pipe."

"The use of a turbine to generate electricity is one of our projects focused on sustainability and energy efficiency. We put this HIGRA turbine into operation to cogenerate electricity, taking advantage of the potential of our Piraí pipeline."

"The work was carried out in record time. In 6 months we put this UCHA (Compact Amphibious Hydrogeneration Plant) into operation, capable of producing 40 kWh, corresponding to 28,800 kWh per month, enough to supply the consumption of around 100 homes."
