The state framework sets the default. Where Duke Energy Carolinas (NC) pays something different, the utility tariff governs and is what the card above reports.
| Compensation mechanism | Monthly netting under Rider NMB or Rider RSC, followed by a Net Excess Energy Credit (NEEC) for remaining net exports; legacy Rider NM uses the applicable rate-schedule energy rate and has a seasonal credit reset. |
|---|---|
| Export rate | No single statewide export rate exists. For the current DEC NMB and RSC riders, the published NEEC is 4.53¢/kWh; the rider describes it as the credit for remaining net excess energy, while RSC first nets energy by TOU period. |
| Rate effective | Current DEC NMB and RSC tariff sheets are effective for service rendered on and after September 1, 2026. The revised residential riders began October 1, 2023; legacy Rider NM remains available only to protected participants through December 31, 2026. |
| Credit rollover | Legacy Rider NM credits may offset charges in future months, subject to the seasonal forfeiture date. NMB and RSC credit remaining monthly net exports at NEEC rather than providing an indefinitely accumulating retail-credit bank. |
| Credit expiration | Legacy Rider NM unused credits are forfeited at the seasonal reset: June 1 for Duke Energy Carolinas and May 31 for Duke Energy Progress. NMB participants may remain on the rider for up to 15 calendar years from the interconnection-application submission date; the tariff does not describe that as an annual credit bank. |
| Annual true-up | Legacy Rider NM seasonal true-up/reset: June 1 for Duke Energy Carolinas and May 31 for Duke Energy Progress. NMB/RSC use monthly netting and NEEC treatment rather than the legacy seasonal retail-credit reset. |
| Aggregate program cap | No statewide aggregate participation cap identified. DEC NMB has an annual capacity allocation of 7,250 kW AC in 2023, 31,900 kW AC in 2024, 35,100 kW AC in 2025, and 38,700 kW AC in 2026; it is reserved first-come, first-served. |
| Program status | Rider NMB is limited by annual capacity and closes to new participants on January 1, 2027; Rider RSC is the alternative current residential rider. This is not a statewide program closure. |
| Grandfathering | Residential legacy Rider NM participants who applied before October 1, 2023 may remain on Rider NM until January 1, 2027, when they transition to Rider NMB; NMB applicants before January 1, 2027 may remain on NMB for up to 15 calendar years from the application submission date. |
| Regulator | North Carolina Utilities Commission (NCUC), with the NCUC Public Staff providing the public net-metering guidance and tariff links. |
| Governing rule | N.C.G.S. § 62-126.4 and Session Law 2017-192 (HB 589), implemented through NCUC-approved net-metering riders and the North Carolina Interconnection Procedures. |
