Description

Note: In April of 2014, S.B. 1189 created the voluntary Distributed Energy Resource Program and mandated that the Public Service Commission write new net metering rules that will supersede all old rules. Customer-generators already a part of net-metering agreements may remain in these existing programs until December 31, 2020. The latest net metering details are available in PSC Docket 2014-246 E.

In August 2009, the South Carolina Public Service Commission issued an order mandating net metering be made available by the regulated electric utilities; the order incorporates a net metering settlement signed by the individual interveners, the Office of Regulatory Staff and the three investor-owned utilities (IOUs). The order detailed the terms of net metering, including ownership of RECs, in South Carolina and standardized the structure of net metering programs offered by the IOUs.

South Carolina Electric & Gas (SCE&G) designed two net-metering options for its South Carolina customers. These options are available to SCE&G customers operating photovoltaic (PV) systems, wind turbines, biomass systems or small hydro-electric systems

Customer net excess generation (NEG) is credited to the customer's next bill at the utility's retail rate, and then surrendered to the utility annually on June 1st. Under one net-metering option, customers must switch to a time-of-use (TOU) tariff that incorporates potentially high demand charges into its fee structure. Under the second option, customers pay an additional monthly fee to net meter. These tariffs involve additional charges that do not apply to customers who do not net meter.

Systems must conform to the Standard for Interconnecting Small Generation 100 kW or Less with Electric Power Systems. For more information, see the utility's program web site.
