In May 2008, the South Carolina Public Service Commission (PSC) issued a directive that required investor-owned electric utilities (IOUs) to provide net metering for customers by July 1, 2008. Unlike most state-level policy actions regarding net metering, this directive did not include any definitions or parameters to govern utility programs. The PSC's vague directive has spawned several widely varying forms of net metering and net billing* programs; many of these utility programs fail to provide the same financial benefits that other states' net metering programs offer.

Several of the approved tariffs require customers to switch to time-of-use (TOU) riders that incorporate high demand charges into their fee structure, while others offer a kilowatt-hour (kWh) credit that is only a fraction of what customers pay for each kWh of electricity. These tariffs generally do not constitute net metering as defined by most other states. In other states, one kilowatt-hour (kWh) generated by the customer has the exact same value as one kWh consumed by the customer, and mandatory TOU tariffs and/or demand charges specific to net metering generally do not apply.

The PSC asked the following IOUs to provide a time-of-use and a flat-rate net metering option for their customers: Progress Energy, Duke Energy, and SCE&G. Santee Cooper has had a net billing pilot program since October 2007.

* Often confused with net metering, net billing is a less appealing financial arrangement for customers who generate their own electricity.
