CHARLOTTE, N.C., April 29, 2024 /PRNewswire/ -- As strong economic development successes and population growth power the Carolinas' energy needs, Duke Energy's goal is to ensure energy reliability for its customers.

Duke Energy recently completed upgrades to the four units at the Bad Creek pumped storage facility in Salem, S.C. The upgrades add a total of 320 megawatts of carbon-free energy to the company's system and brings the total capacity of the station to 1,680 megawatts.

A flexible, dynamic, efficient and green way to store and deliver large quantities of energy, pumped storage hydro plants store and generate energy by moving water between two reservoirs at different elevations. 

Coming online in 1991, Bad Creek is designed to produce significant amounts of energy when our customers need it most, performing a vital role as the largest "battery" on the company's system.

"This investment in Bad Creek demonstrates our commitment to improving reliability across the Carolinas. Pumped storage technology gives us operational flexibility, allowing us to store energy and then deploy that energy when customer demand is highest," said Preston Gillespie, executive vice president and chief generation officer and enterprise operational excellence. "Expanding our energy storage capabilities is just one of the many steps we are taking in the next phase of our energy transition."

The units were upgraded in phases, adding 80 MW of capacity to each new pump turbine. Unit 2 was completed in 2020, unit 1 was completed in 2021, unit three was completed in 2023 and unit 4 was completed in April.

Duke Energy is currently working to extend the license of the Bad Creek pumped hydro storage facility, which is set to expire in 2027. In addition to this upgrade project, Duke Energy is evaluating the potential to add a second powerhouse at Bad Creek that would further help Duke Energy add capacity to the system as well as address increasing system variability, from the growth of solar and customer usage, in a reliable and affordable way. If pursued, the second powerhouse could be in-service as earlier as 2034.

"From population growth to the expansion of manufacturing and other major economic development wins, the Carolinas are booming," said Mike Callahan, Duke Energy's South Carolina president. "We must have a diverse energy mix to account for this growth on the coldest winter nights and the warmest summer days. We continue to look at solutions like expanding Bad Creek to make sure the power is there when customers need it, and it is as affordable as possible – providing certainty as they go about their daily lives."

Expanding operations at Bad Creek also provides significant economic benefits of $7.3 billion to South Carolina, as the state benefits from construction and general infrastructure activity, by 2033.
