SCE&G - Customer Scale Solar Program

September 16, 2016


South Carolina Electric & Gas (SCE&G) Customer Scale Solar Rebate Program, a part of SCE&G's voluntary Distributed Energy Resource Program, was approved by an order issued on July 15, 2015.

Program Details

SCE&G offers incentives for residential customers and nonresidential customers. Incentives are limited to approximately 42 megawatts (MW) of installed capacity, with 33 MW for distributed systems under 1 MW and 9 MW for systems under 20 kilowatts (kW).

SCE&G will only allow a customer-generator to size a renewable generator in such a manner so that the renewable generation will off-set part, or all, of the customer’s own electrical energy requirements, as determined by historic data on the customer’s annual electricity usage or as estimated by SCE&G where annual usage data does not exist.

Residential Performance Based Incentive

The performance based incentive (PBI) for residential systems under 20 kW are as follows:

  • 0 MW to 2.5 MW cumulative capacity: 4 cents per kilowatt hour
  • 2.5 MW to 5 MW cumulative capacity: 3 cents per kilowatt hour
  • 5 to 7 MW cumulative capacity: 2 cents per kilowatt hour
  • 7 to 9 MW cumulative capacity: 1 cent per kilowatt hour

The PBI residential incentive is retroactively available for systems installed after January 1, 2015 for all customers who join the new Net Metering tariff. At the discretion of the customer, some incentives may be claimed by the customer or applied to companies installing or leasing systems.

Non-Residential Bill Credit Agreement

Nonresidential customers will be eligible for a Bill Credit Agreement equal to 14 to 22 cents per kWh generated depending upon system size and the customer’s rate schedule and tax status. If these systems are under 20 kW, they will count towards the 9 MW goal for small systems, but will not also be eligible for the residential PBI incentive.


The company shall initially 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.
