Duke Energy Carolinas Customer Scale Rebate Program

May 09, 2023


Duke Energy Carolinas' Customer Scale Solar Rebate Program, a part of Duke Energy's voluntary Distributed Energy Resource Program,  was approved by an order issued on July 15, 2015.

Program Details

Duke Energy Carolinas will offer a rebate of $1.00 per DC watt for residential customers and nonresidential customers. Rebates are limited to 40 megawatts (MW), with 30 MW for distributed systems under 2 MW and 10 MW for systems under 20 kilowatts (kW). At the customer's discretion, the rebate may be claimed by the customer or applied to companies installing or leasing systems.

For each successive installation of 2 megawatts (MW) of residential solar and 6 MW of non-residential solar, Duke Energy Carolinas may review, evaluate, and propose new rebate amounts within 25% of the initial $1.00 per DC watt. Rebate modifications more than 25% of the current value must be approved by the South Carolina Public Service Commission.

The program is retroactive for customers installing systems after January 1, 2015.


The company shall intially retain ownership of renewable energy credits until all Distributed Energy Resource Program  (DERP) costs are recovered and DERP charges are removed from customer bills. Then, REC ownership will shift to customer-generators.
