Duke Energy Solar Choice in South Carolina.

Time-of-use, critical-peak days, and an avoided-cost credit for excess. A battery can help you use more of your own solar. It depends on your rate and usage.

The rate

Does Duke Energy still offer net metering in South Carolina?

Retail one-for-one net metering is not the plan for a new Duke Energy South Carolina application. Applications after May 31, 2021 are on Solar Choice. Applications from May 16, 2019 through May 31, 2021 keep the older retail credit through May 31, 2029. Applications before May 16, 2019 kept it through December 31, 2025. Those dates are in S.C. Code section 58-40-20 and in Duke's legacy Rider RNM. They follow the original application date, including for a later owner.

Duke Energy Carolinas and Duke Energy Progress in South Carolina both use this structure. Detail Solar LLC is not affiliated with Duke Energy. The tariff on your account is the one that controls.

Residential Solar Choice and R-STOU

Solar Choice here is Rider RSC together with Schedule R-STOU. Applications from June 1, 2021 used interim riders. From January 1, 2022, RSC and R-STOU apply. R-STOU is a time-of-use schedule with critical peak pricing. Duke can call up to 20 critical-peak days a year, with notice the day before. On-peak hours are weekday evenings from March through November and weekday mornings from December through February. Super-off-peak is overnight from March through November.

Energy is netted monthly inside those time periods. Net excess is credited at an avoided-cost rate. There is a monthly minimum, and a grid access fee applies to systems over 15 kW. Those amounts change, so they are not printed here. Read the currentSchedule R-STOUandRider RSC. The Office of Regulatory Staff has described this structure as fixed for about ten years.

Net Metering Transition for pre-2019 homes

Rider NMT is the Net Metering Transition rider, for customers coming off retail net metering. For systems applied for before May 16, 2019, the rider's published term runs from January 1, 2026 through December 31, 2035. That span is how long the rider's terms run. It is not a sign-up deadline.

NMT uses monthly netting. Excess is credited at avoided cost. It does not put you on the Solar Choice time-of-use schedule, and its minimum charge is lower than R-STOU. It includes a non-bypassable charge tied to base-rate increases after the older net metering ends. Customers elect NMT. If they do not, they move to Rider RSC and Schedule R-STOU. Duke sets the enrollment window. Confirm the last day with Duke before you rely on a date.

For systems applied for from May 16, 2019 through May 31, 2021, retail net metering continues through May 31, 2029, and the transition rider's published term begins after that. The original application date still controls if someone else now owns the house. Duke's rider and customer letter are linked in the sources.

Batteries

Power Manager Battery Control

Power Manager Battery Control is a real Duke Energy South Carolina program, Rider PM SC. It can pay a monthly bill credit based on the battery's kilowatts, in exchange for letting Duke dispatch the battery for a limited number of events a year. Duke keeps a reserve. Opt-outs are limited. The program asks for an internet connection, a model Duke has approved, and an interconnection that meets Duke's rules.

The credit amount is onRider PM SCand onDuke's program page. It can change, so it is not printed here. Whether those credits help depends on your rate and usage. We can help you understand what Duke asks for. Enrollment is with Duke.

PowerPair is North Carolina only

Duke's PowerPair rebate for solar plus a battery is a North Carolina program. It is not a South Carolina rebate. A page that offers PowerPair to a Greenville address is mixing up the Carolinas.

How a battery fits the plan

On Solar Choice, panels tend to produce at midday. The higher-priced hours are weekday evenings, winter mornings, and up to 20 critical-peak days. A battery can help you keep that midday solar for those hours instead of exporting it at an avoided-cost credit.

On the transition rider, netting is monthly and there is no time-of-use requirement. Excess still credits at avoided cost. A battery can still help you use your own solar in the evening rather than exporting it. Backup during an outage is a separate job, and it depends on transfer equipment and on Duke's rules. In each case it depends on your rate and usage. Adding the battery to panels you already have isits own page.

Interconnection and permission to operate

Duke uses the South Carolina Generator Interconnection Procedures, Section 2, for home systems of 20 kW AC or less. The account holder signs Attachment 7. Do not energize until Duke sends written approval to energize, which Duke calls permission to operate. If the home is sold, the agreement does not survive the transfer, and the new owner submits a new request within 20 business days. A battery or an inverter change usually means paperwork first. Duke decides what review is required.

Questions

Does Duke Energy still offer net metering in South Carolina?

Applications before May 16, 2019 kept it through December 31, 2025. After that, the Net Metering Transition rider is the option customers elect. If they do not elect it, they move to Solar Choice.

That span is the term of the rider, not a sign-up deadline. It uses monthly netting, credits excess at avoided cost, and does not require time-of-use. Customers have to elect it. Confirm the last day to elect with Duke.
