SPIC Brasil and GE Vernova accelerate the modernization of the São Simão hydroelectric plant, achieving important performance milestones

SÂO PAULO, Brazil (September 14, 2026) - SPIC Brasil, operator of the São Simão Hydroelectric Power Plant (UHE), located on the border between Goiás and Minas Gerais, and GE Vernova Inc. (NYSE:GEV) today announced the successful completion of the modernization of Generating Unit (UG) 3. This is the third unit, out of a total of six, to undergo complete renovation. This milestone was achieved in 10.3 months, a shorter period than that recorded in the previous units and below the regulatory limit of 12 months established by the National System Operator (ONS) and the National Electric Energy Agency (Aneel).

The modernization of the 1,710 MW power plant, which supplies energy to approximately 6 million homes, is being carried out by a consortium led by GE Vernova and including Powerchina, responsible for supplying the hydromechanical, SDSC, and electrical and mechanical BOP systems. By integrating specialized engineering, proprietary technology, and a unified focus on operational excellence, the project helps ensure that the plant will operate with superior reliability for the next 30 years.

Technical execution and operational synergy
The project involved extremely complex logistical and engineering challenges. The dismantling phase alone, necessary to begin the modernization, took approximately three months. During the process, teams moved gigantic structures, handling parts weighing up to 410 tons, including the operation of a 12-meter-high railcar gate.

With the delivery of UG3, the schedule is progressing and the team is already preparing for the shutdown of UG1, which will be the fourth generating unit on the list to begin its modernization cycle.

“The lessons learned during the modernizations of previous generating units have allowed us to put continuous improvement into practice, which is one of our company’s core principles. Furthermore, we are capturing synergies with the plant expansion project, the future UG7. Everything is very well connected. Even with distinct teams dedicated to each project, we operate with similar processes, share resources, and maintain a high level of collaboration to help ensure the excellence and safety of both projects,” highlights Adriana Waltrick, CEO of SPIC Brasil.

GE Vernova manages the entire engineering, integration, installation, and commissioning process for the plant’s main systems, including turbines, generators, and auxiliary equipment.

“The São Simão Hydroelectric Plant is a fundamental asset for the country’s energy. Completing this challenging stage, well below the average industry timeframe, reinforces the technical capacity of our team. This successful collaboration with SPIC Brasil and our consortium partner, applying lessons learned and utilizing GE Vernova’s experience in modernization projects, demonstrates how the efficient refurbishment of existing plants is, today, one of the smartest and most competitive ways to help support national energy security and update the infrastructure of the electricity sector,” stated Cláudio Trejger, CEO of Hydro Power at GE Vernova in Latin America.

Project scope and strategic investment
The robust modernization program is driven by an investment exceeding R$ 1.2 billion distributed over ten years. The initiative aims to increase the efficiency, reliability, and safety of the São Simão Hydroelectric Plant, helping to support its operational excellence for another three decades.

The complete project for the six units is expected for completion in 2029 and is structured in seven major packages, ranging from the replacement of transformers and the refurbishment of overhead cranes to the complete transition of control systems – which will change from an analog architecture to a 100% digital one.
