On Thursday, October 30, Aliança Energia completed the modernization of the Fish Transposition System (STP) of the Funil HPP, a project that represents a milestone for the reliability, efficiency and environmental control of the operation. The operational delivery was formalized on the same date, after training with the Operation and Maintenance team responsible for the system. The beginning of the new cycle of fish transposition is scheduled for this Saturday, November 1st.
According to the Electrical and Electronic O&M Technician Elvis da Silva Reis, responsible for conducting the project, “the initiative began in 2024, with the objective of replacing obsolete electrical and electronic equipment, which had a high failure rate and no longer fully met the current technical standards and norms.”
The modernization marks a technological leap that consolidates the performance guided by sustainability, safety and operational excellence.
This work was the result of the integration between the areas of Operation & Maintenance, Engineering and Environment, conducted in a safe and collaborative manner. This union reflects the company’s values: life first, social and environmental responsibility and continuous search for excellence.
Among the main improvements implemented, the following stand out:
- Automation: installation of a complete control set with PLCs (Programmable Logic Controllers), which allow the automatic positioning of the fish elevator.
- Control: operation via HMI (Human-Machine Interface) and also locally, ensuring flexibility and precision in maneuvers.
- Infrastructure: installation of six local panels to serve all STP subsystems.
- Redundancy: implementation of an alternative power supply, increasing safety and operational availability.
- Supervision: improvement of the Supervision and Control System (SDSC), which now allows for even more complete and real-time monitoring.
Additional improvements are in the implementation phase, expected to be completed by December 2025. Among the main actions in progress, the inclusion of sensors in the elevator bucket for real-time monitoring of temperature, oxygenation and pH of the water stands out, contributing to greater control and efficiency of the process.
With all these innovations, the STP of the Funil HPP will operate with state-of-the-art technology, further strengthening the efficiency of the processes and the environmental management of the plant.
