Pļaviņas Hydropower Plant, commissioned in the late 1960s, is the largest hydropower plant in the Baltics and one of the largest in the European Union. The project included significant infrastructure modernization to improve plant efficiency and working conditions. Obsolete reinforced concrete elements such as sidewalks, beams, and crane rails were dismantled and replaced with new steel beams. The new rails were installed using the Gantrex rail system, significantly improving crane operational conditions by reducing elastic deflection and ensuring structural stability both longitudinally and transversely. Since the work was performed without crane assistance, the project required extremely careful planning and precise execution. Additionally, 330 kV transformers were replaced, and a new 330 kV cable system was constructed. A cable section 4533 meters long was installed, along with 27 cable end terminations and three joint sleeves. The project was implemented while maintaining continuous power generation and adhering to strict work organization requirements. This reconstruction was a crucial step not only in improving Pļaviņas HPP’s operations but also in strengthening Latvia’s energy infrastructure.
