No legislative activities on smart grid have been identified for South Carolina.
The Public Service Commission of South Carolina approved distributed generators by 1993, including net metering by 2008. The Commission had established Time-of-Use for residential and business customers by 2007, and offered real time pricing options to businesses the same year. Methods for load/demand side management, with direct load control for businesses and residential customers being approved by 2005. 
“In August 2007, the South Carolina Public Service Commission decided not to adopt PURPA Standard 14 (“Time-Based Metering and Communications”) as enacted in EPACT 2005. In its August 2007 Order, the Commission stated that all regulated utilities within the state already offer time-based rates. In the same Order, however, the Commission found that there is a “conspicuous lack of focus” on residential and commercial smart metering, which may be due to a lack of awareness of the “availability and capability” of smart meters. As a result, it directed utilities to continue to make smart meters available to all customers and to propose within 180 days a campaign to educate consumers about smart metering. In February 2008, South Carolina Electric & Gas Company, Duke Energy Carolinas, and Progress Energy Carolina complied with the August 2007 Order and filed their “communication plans.” No subsequent activity in the proceeding was identified for this report.” 
Distributed generators include qualifying cogeneration, small power production facilities, and net metering installations. Where pricing is a variable rate energy credit for on peak and off peak rate or energy is rolled forward to future months.
Time-of-Use breaks the cost for electricity seasonally into periods with on-peak demand and energy priced on-peak or off-peak.
The real time pricing is based on the marginal cost of energy by the company and provided to the customer eight hours in advance of the day the power flows. It also includes hourly pricing rates where pricing is based on the expected marginal production cost.
Load/demand side management includes direct load control, thermal energy storage, and interruptible accounts. Direct load control includes utility controlled systems such as HVAC and water heating. Thermal energy storage charges a significantly reduced rate for off-peak usage of customer controlled thermal energy storage systems. Interruptible account notify the customer in advance of having to shed load and then charge a significant penalty if the contracted load amount is not reduced to a company specified level
