GE Vernova Partners with Dominion Energy to Modernize Saluda Hydropower Plant

Modernization of Historic Hydropower Plant to Boost Efficiency and Environmental Impact
GE Vernova has been awarded a contract by Dominion Energy South Carolina to modernize two turbines at the Saluda Hydropower Plant, a 206MW facility located on the Saluda River near Columbia, South Carolina. The project aims to enhance the plant’s operational efficiency, reliability, and flexibility, while extending its operational lifespan. GE Vernova will replace the turbines in Units 1 and 3 with advanced aerating turbines and rehabilitate the generator in Unit 3. The first unit upgrade is scheduled for completion by 2027.

Aerating Turbine Technology to Improve Water Quality and Support Aquatic Life
A standout feature of the modernization is the installation of GE Vernova’s patented aerating turbine technology. This innovative solution increases the levels of dissolved oxygen in the water, which is expected to significantly improve water quality in the Saluda River. By enhancing the oxygenation process, the turbines will support local aquatic life and help preserve the natural ecosystem. This technology has already been successfully deployed in other hydropower projects, including the High Rock project in North Carolina, further demonstrating its potential environmental benefits.

Saluda Hydropower Plant: A Legacy of Service and Sustainability
The Saluda Hydropower Plant has been serving South Carolina since 1930 and is an integral part of the region’s infrastructure. Originally constructed to support the growth of Columbia’s textile industry, the plant has since contributed to various functions such as flood control, water supply, and recreation. The facility created Lake Murray, a 48,000-acre lake that remains a popular destination for locals. With its nearly century-long history, the plant currently operates five Francis hydropower units, all of which will benefit from the ongoing modernization efforts.

Strengthening Long-Term Reliability and Partnership
This contract marks another chapter in the long-standing relationship between GE Vernova and Dominion Energy, with nearly 70% of Dominion Energy’s fleet utilizing GE Vernova’s technology. The modernization of Saluda is seen as a critical investment in maintaining the plant’s reliability and efficiency, ensuring that it continues to meet the energy needs of South Carolina for decades to come. Dominion Energy’s Vice President of Generation, Iris Griffin, highlighted that replacing the turbines will help maintain the facility’s long-term viability and continue providing safe, reliable power to the region.
