The state framework sets the default. Where Dominion Energy South Carolina pays something different, the utility tariff governs and is what the card above reports.
| Compensation mechanism | Utility-specific Solar Choice metering for new applications; qualifying pre-June 1, 2021 applicants retain legacy net energy metering. Santee Cooper uses its Distributed Generation Rider and does not provide one-to-one retail net metering. |
|---|---|
| Export rate | No single statewide export rate exists. Santee Cooper's DG-25 rider lists $0.0415/kWh. Dominion Energy South Carolina's residential Solar Choice credits the applicable Rate 5 TOU energy rates and pays remaining November-cycle excess at avoided cost. For Duke, the most recent ORS-published rate overview (dated January 2022) lists $0.0270/kWh for Duke Energy Carolinas and $0.0230/kWh for Duke Energy Progress; those are that document's approved Solar Choice rates, not a current-year figure, and the filed tariffs control. |
| Rate effective | Solar Choice tariffs began June 1, 2021; the cited Dominion residential tariff is effective after the first billing cycle of July 2026; Santee Cooper DG-25 was adopted December 9, 2024. |
| Credit rollover | DEC/DEP excess credit remains on the account and carries to the next year; Dominion carries remaining TOU excess to the following month; Santee Cooper applies a monthly credit below $50 to the next billing month. |
| Credit expiration | Dominion pays accumulated excess at avoided cost during November billing cycles and zeroes the account. Santee Cooper pays a monthly net credit of at least $50 by check and applies a smaller credit to the next month; no statewide expiration rule exists. |
| Annual true-up | No statewide true-up date exists. Dominion uses November billing cycles for annual zero-out/payment; Santee Cooper settles monthly. |
| Aggregate program cap | The former Act 236 framework capped net-metering capacity at 2% of the utility's previous five-year average South Carolina retail peak demand. Current Solar Choice capacity limits are utility-specific and PSC-decided, not one statewide number. |
| Program status | No statewide open/full/closed status. The historic 2% cap led to successor Solar Choice tariffs; current capacity status must be checked in each utility tariff or PSC docket. |
| Grandfathering | Applicants before May 16, 2019 receive full-retail credit through December 31, 2025; applicants from May 16, 2019 through May 31, 2021 receive full-retail credit through May 31, 2029. Solar Choice applies to new customers from June 1, 2021. |
| Regulator | The Public Service Commission of South Carolina regulates investor-owned utilities, with the Office of Regulatory Staff representing consumers. Santee Cooper is the South Carolina Public Service Authority. |
| Governing rule | S.C. Code Ann. Sections 58-40-10 and 58-40-20, as amended by Act 236 of 2014 and Act 62 of 2019; current text also reflects 2025 Act 41. |
