GRDA Modernizes Salina Pumped Storage Project for Future Demands
After more than 50 years of service, the Grand River Dam Authority (GRDA) is set to upgrade and modernize two hydroelectric pump-turbine units at the Salina Pumped Storage Project (SPSP). This $56 million project, contracted to Litostroj, US, LLC, aims to enhance the efficiency, flexibility, and reliability of Units 5 and 6, which have been operational since 1972. The modernization will support GRDA’s efforts to meet evolving grid demands and improve market responsiveness. Additionally, research from this project may benefit other pumped storage facilities across the U.S. The project, beginning in mid-February 2025, is part of GRDA’s broader initiative to ensure a reliable electricity supply, including the construction of a new 420-MW gas generating unit at the Grand River Energy Center.
