Sell Renewable Energy

You may be eligible to sell us electricity at our standard or negotiated rates and conditions if you own qualifying generation such as wind, solar, or hydroelectric that is interconnected directly to the Duke Energy Progress electric grid. Unless otherwise negotiated, under these options for the purchase of qualifying energy, you as the generator owner would maintain all Renewable Energy Credits associated with the output. 

All generators that intend to sell energy to Duke Energy Progress are fully responsible for adhering to all utility requirements, applicable federal rules and regulations, state and local ordinances and regulations adopted by the North Carolina Utilities Commission or the South Carolina Public Service Commission (the governing bodies of regulated utilities in the Carolinas). This website does not establish a legal or binding arrangement; it intended solely to provide access to general information about potential options that may be available through Duke Energy Progress. Generators are responsible for consulting with appropriate legal and energy professionals in determining if generation ownership is the right choice and for assistance in navigating applicable requirements and procedures.

Options at a Glance

What you need to know:

  • All customers installing generation must follow interconnection procedures as adopted by the North Carolina Utilities Commission (NCUC). 
  • All customers installing generation must provide a Report of Proposed Construction or, if more than 2 megawatts (MW), receive a Certificate of Public Convenience and Necessity from the NCUC.
  • All customers that sell power to Duke Energy Progress must enter a Power Purchase Agreement (PPA):
    • Customers with renewable generation of 5 MW or below are likely eligible for standard purchase rates under the Cogeneration and Small Power Producer (CSP) tariff.  A standard PPA must be executed, as provided by Duke Energy Progress.
    • Renewable energy generators that do not qualify for standard purchase rates may pursue a negotiated PPA.

Eligibility for the standard option:

In order to be eligible for the Duke Energy Progress standard rates, a generator must:

  • Be a Qualifying Facility;
  • Have a capacity of 5 MW or less; and
  • Be hydroelectric, solar, wind, or fueled by trash or methane derived from landfills, hog waste, poultry waste, or non-animal biomass.

Other Qualifying Facilities with a capacity of 3 MW or less, including co-generators, are eligible.

How do I use the CSP tariff in the standard option?

Eligible Qualifying Facilities are paid under the CSP tariff, which is governed by the accompanying Terms and Conditions. The CSP tariff provides the rates and requirements that a generator must follow in order to sell power. Customers may choose to sell power at variable (roughly 2 years), 5-year, 10-year, or 15-year terms. Under a variable term, rates will update on a biennial basis concurrent with Duke Energy Progress' filings at the NCUC. If choosing the 5, 10, or 15-year option, you must remain on that rate for the entire term.

The actual payment to a customer depends on the amount of energy that is delivered to the electric grid, as measured by a Duke Energy Progress meter. Each kilowatt-hour (kWh) of energy is eligible for both an energy and capacity payment, which are applied to the production depending on the month and time of day that the kWh is delivered. 

For instance, energy rates vary for energy delivered between on-peak and off-peak hours.  Capacity payments vary for energy delivered during summer or non-summer months.  The CSP tariff has full details regarding eligibility and rates.  We recommend that you review the tariff to determine potential payments, based on your estimated production.  If you are not selling the entire output of the system to Duke Energy Progress or are not directly interconnected to the Duke Energy Progress electric system, energy-only rates apply.
