In a significant move for Slovakia's energy infrastructure, international technology group ANDRITZ, in partnership with Slovak engineering firm VUJE, has been awarded a contract to modernize the Gabcikovo hydroelectric power plant on the Danube. The contract, placed by VODOHOSPODARSKA VYSTAVBA, marks a crucial investment in the largest hydroelectric facility in Slovakia, which accounts for approximately 10% of the nation's electricity production. The project's importance extends beyond mere maintenance; it is a strategic upgrade to ensure reliable and sustainable power generation for decades to come.
The comprehensive modernization will focus on the plant's electromechanical equipment, which currently has a total capacity of 720 MW. The order value is in the mid three-digit million-euro range and has been included in ANDRITZ's order intake for the third quarter of 2026. This investment underscores the critical role the plant plays in Slovakia's energy mix and the commitment to modernizing renewable energy assets to meet future demands.
The scope of work is extensive, involving the gradual refurbishment of the eight Kaplan turbine-generator units to the latest technical standards. The primary objectives are to improve efficiency and availability while extending the technical service life of key operating equipment by at least 30 years. This long-term perspective is essential for the plant's continued contribution to the country's energy security and its alignment with broader European Union climate targets.
ANDRITZ will supply a wide range of services and components, including model testing, engineering, manufacturing, installation, and commissioning. The modernization will cover key turbine and generator components, automation systems, excitation, protection, and control systems, as well as the renewal of transformers and auxiliary electrical systems. By upgrading these critical elements, the project will enhance the plant's performance and integrate advanced digital technologies for optimized operations.
A key aspect of the project is the sequential execution of work, which will allow the plant to maintain availability during the modernization process. This careful planning minimizes the impact on ongoing operations, ensuring that Slovakia's electricity supply remains stable throughout the project's duration. The partnership between ANDRITZ and VUJE combines international expertise with local knowledge, a synergy that is vital for the successful execution of such a complex undertaking.
The Gabcikovo power plant is not only a cornerstone of Slovakia's energy system but also a symbol of the region's commitment to renewable energy. With this modernization, the plant will continue to provide clean, reliable power, supporting the country's transition to a low-carbon economy. For ANDRITZ, this project reinforces its position as a global leader in hydropower technology, with over 185 years of innovation and more than 492 GW of installed capacity worldwide. The company's holistic approach, from water-to-wire solutions to comprehensive lifecycle services, ensures that customers receive sustainable and efficient energy solutions.
As Slovakia and the wider region grapple with the challenges of energy security and climate change, investments like this modernization are crucial. They not only preserve existing renewable assets but also enhance their efficiency, contributing to a more resilient and sustainable energy grid. This project is a clear signal that hydropower remains a vital component of the global renewable energy mix, and its continued evolution is essential for meeting future energy demands.
