ANDRITZ modernizes Brazil’s Itumbiara hydropower plant to enhance grid reliability

When energy providers look to future-proof aging infrastructure, the choice of a technology partner often hinges on the ability to integrate sophisticated digital control systems with heavy mechanical engineering. The recent agreement between AXIA Energia and ANDRITZ for the modernization of the 2,082 MW Itumbiara hydropower plant — one of Brazil’s largest facilities — serves as a primary example of how specialized automation platforms differentiate themselves from standard industrial solutions by addressing both mechanical wear and digital obsolescence.

Modernizing Large-Scale Renewable Assets
The Itumbiara plant, situated between Goiás and Minas Gerais, has provided consistent power since 1980. After four decades of service, the facility requires more than just routine maintenance to remain competitive in a modern grid. The comprehensive upgrade includes the complete renewal of protection, control, and supervision systems. By replacing voltage and speed governors along with critical mechanical components, the project ensures that the plant can meet current safety and efficiency standards that were non-existent at the time of its original commissioning.

Technological Superiority through Integrated Control Platforms
What distinguishes this modernization effort from typical hardware replacements is the implementation of specialized digital ecosystems like the HIPASE platform. Unlike generic automation tools, these proprietary systems are designed specifically for the high-stakes environment of hydropower, integrating generator excitation and turbine governing into a single, cohesive interface. This integration is vital for strengthening operational resilience and securing the facility against modern cybersecurity threats, a growing concern for national energy grids.

Securing Brazil’s Energy Future
The contract, valued in the lower double-digit million-euro range and recorded in late 2025, underscores the economic necessity of high-tier automation. By utilizing advanced monitoring and synchronization technologies, the project extends the lifespan of the Itumbiara plant while enhancing its overall reliability. This technological advancement does not merely maintain the status quo; it optimizes the facility to serve as a high-performance, sustainable cornerstone of Brazil’s long-term energy security.
