South Carolina at a glance
South Carolina has nuclear-heavy generation, and rates still reflect recovery of costs from the abandoned VC Summer reactor project, a construction failure households continue to pay for. Retail service is regulated. Long humid summers make cooling the dominant load, with widespread electric heating adding a real winter component.
