The South Carolina electric grid is part of the North American Electric Reliability Corporation (NERC) Eastern Interconnection. In South Carolina, the SERC Reliability Corporation is the regional entity, under the NERC, charged with developing reliability standards and monitoring compliance for all owners, operators, and users of the bulk electric system. VACAR-South, a sub-region of SERC, is the registered electric reliability coordinator for South Carolina.
South Carolina has four balancing authorities:
- Duke Energy Carolinas, LLC;
