MONCKS CORNER, S.C. — Santee Cooper officials say crews are taking steps to prepare for the potential impacts of anticipated winter weather, as frigid temperatures forecast for the coming days could place added strain on the state’s electric system.
The state-owned electric and water utility, which provides power to nearly 2 million South Carolinians either directly or through local electric cooperatives, moved to Operating Condition (OpCon) 4 as of noon Thursday. The alert level signals a possible threat to the electric system, though impacts remain uncertain or limited at this stage.
Under OpCon 4, Santee Cooper officials say preparations are focused on ensuring system reliability and readiness. That includes completing freeze protection checklists for generating station equipment, arranging for additional personnel to be on site in case road closures limit travel, securing sufficient fuel and supply inventories, and coordinating with neighboring utilities to maintain grid stability.
“Santee Cooper is securing resources to prepare for the frigid temperatures forecast for the weekend,” said Marty Watson, senior director of commercial and customer service. “The extreme cold weather means customers will be using more electricity. As a result, bills may increase.”

Watson encouraged customers to remain mindful of their energy usage and take steps to conserve power where possible to help offset higher costs.
Utility officials note that home heating is the primary driver of increased electricity use during prolonged cold weather. Heat pumps tend to run longer and harder to maintain indoor temperatures, and during freezing conditions, emergency heat systems—often referred to as heat strips—may activate, significantly increasing electricity consumption.
To help manage usage while staying comfortable, Santee Cooper recommends customers:
- Set thermostats to 68 degrees or lower
- Dress warmly with layers, socks and blankets
- Seal air leaks around windows and doors
- Close window coverings at night to reduce drafts
- Replace air filters regularly to keep heating systems running efficiently
- Avoid running large appliances such as dishwashers and clothes dryers during peak hours between 6 and 9 a.m.
Officials also noted that higher regional electricity demand during cold weather can drive up fuel usage across the Southeast. Many utilities, including Santee Cooper, adjust fuel charges based on actual fuel costs, which may increase during periods of extreme demand.
Customers can report power outages, track service updates and find storm safety information—including guidance on generators and downed power lines—by visiting stormcenter.santeecooper.com or calling 888-769-7688.
Santee Cooper officials said they will continue monitoring conditions and adjusting operations as needed as the winter weather event unfolds.
