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:

Are you eligible for the standard option?

In order to be eligible for Duke Energy Progress’s 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 Purchased Power tariff in the standard option?

Eligible Qualifying Facilities are paid under the Purchased Power tariff, which is governed by the accompanying Terms and Conditions. The Purchased Power 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’s 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 Purchased Power 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.

A generating facility proposing to sell electricity to Duke Energy must first meet the requirements of a “Qualifying Facility" (QF) as defined by the Public Utility Regulatory Policies Act of 1978 (PURPA) and the Federal Energy Regulatory Commission (FERC) regulations implementing PURPA.

Cogeneration facilities and small power production facilities that achieve the necessary federal standards can become a “Qualifying Facility” and be eligible for the rates and exemptions established in accordance with Section 210 of PURPA.  NCUC Docket E-100, Sub 140 identifies the standard rates and contract terms for a Qualifying Facility.

To establish a Legal Enforceable Obligation (LEO), a QF must:

  1. Self-certify at FERC as a Qualifying Facility
  2. Make a commitment to sell the output of the facility to the utility pursuant to PURPA and via the use of the approved Notice of Commitment to Sell Form
  3. Be in receipt of a Certificate of Public Convenience and Necessity ("CPCN") or have filed a Report of Proposed Construction ("ROPC")

Please note: The submission of an interconnection request does not constitute an indication of a QF’s commitment to sell the output of a facility to the utility. 

For information on submitting Notice of Commitment to Sell Form, please see:
