AES Tietê
AES Tietê improves the safety of its dams with AVEVA PI System
AES Tietê, a major hydroelectric power producer in the state of São Paulo, must make extremely fast decisions to prevent flooding at its dams. Its organization relied on remotely operating twelve separate facilities and struggled to compile data quickly enough to produce useful real-time analyses. Deploying AVEVA PI System changed the situation by feeding accurate models and flow forecasts that help teams anticipate increases in hydraulic pressure and release volumes at the right time. Information now flows quickly between sites and the operations center, allowing operators to respond in time to the most sensitive emergencies. Remote plant control is more accurate and reliable, supporting AES Tietê's essential mission: preventing disasters and ensuring safe, efficient hydroelectric generation.
FAQ
How does AVEVA PI System secure the operation of hydroelectric dams?
AES Tietê operates 12 separate hydroelectric facilities in the state of São Paulo. AVEVA PI System feeds accurate models and flow forecasts that help teams anticipate increases in hydraulic pressure and release water at the right time. This real-time data management creates redundant safety protocols, which are essential to preventing downstream flooding and protecting local communities. Industrial supervision becomes a genuine public safety tool.
Why is flow forecasting critical for a hydroelectric producer?
Flow forecasting drives two major issues: safety (flood prevention) and industrial performance (production optimization). AVEVA PI System collects hydrological, meteorological and operational data, then feeds predictive models that anticipate changes in reservoir levels. For AES Tietê, this foresight makes it possible to balance storing water for production against releasing it for safety, turning water management into an operational and environmental advantage.
How can 12 remote facilities be managed from a single center?
AVEVA PI System centralizes real-time data from AES Tietê's 12 hydroelectric plants in a single control center. Information flows quickly between remote sites and operators, enabling faster emergency decisions. Remote control becomes more accurate and reliable thanks to data consolidation. It is a reference architecture for multi-site operators who must quickly balance production, safety and environmental compliance without traveling to each facility.
What safety protocols can a real-time data system support?
AVEVA PI System enables AES Tietê to build redundant safety protocols: multi-level alerts, cross-validation of measurements, automatic triggering of emergency procedures and full historization for post-event analysis. Redundancy of data and models eliminates blind spots. In the hydroelectric sector, where a late decision can cause a disaster, this software robustness is as important as the mechanical robustness of the structures.
How does AVEVA support the transition to more reliable hydroelectric production?
For AES Tietê, AVEVA PI System turned reactive operations into predictive operations. Operators no longer simply endure hydrological variations: they anticipate them using models fed with real-time data. This digital transformation improves plant availability, optimizes renewable energy production and strengthens AES Tietê's core mission: preventing disasters while ensuring safe, efficient hydroelectric production that meets contractual and environmental commitments.
