SC Standard Option Toolkit

Sell energy from qualifying generation up to 100 kW

Customers of Duke Energy Progress may “Sell All” of the electricity generated by their renewable sources by directly interconnecting the system to the grid. To connect your South Carolina renewable energy source that is less than 100 kilowatts (kW) to the grid, you will be required to enter an interconnection agreement and a sale agreement.

A step-by-step outline for establishing a “Sell All” renewable resource is provided below.

Step 1: Request Approval for Interconnection

All Duke Energy Progress customers that install renewable generation who intend to interconnect or operate in parallel with the utility grid must adhere to all requirements and conditions within the SC Interconnection Standard. Customers that own generation facilities such as solar and wind, that are 100 kW or less in nameplate capacity will begin the interconnection process by reviewing the Interconnection Standards and then submitting the Application to Interconnect. The Interconnection Request must be completed in its entirety and submitted with the requirements below. If the system is not self-installed the contact information of the installer/electrician should be listed on the request.

1) Application to Interconnect

2) One-line Diagram*

3) Copy of Insurance Declaration of Coverage –The required coverage shall be a applicable standard homeowner’s or building owner’s insurance policy with liability coverage in the amount specified below.

  • Residential: $100,000 per occurrence
  • Non-Residential: $300,000 per occurrence

Submit the Interconnection Request and other requirements above to the following address below.

Duke Energy Corporation
Mail Code: EM442

After evaluation of the received material a Duke Energy Progress representative will issue contingent approval for construction of the facility provided the facility meet all interconnection and safety requirements.
