A variety of electric rate options are available to both new and expanding customers. Below are links to rate information for North Carolina and South Carolina. You will need Adobe Acrobat Reader to view these files.

Due to the number of variables which may have a major impact upon industrial rates, calculating an accurate estimate of a new customer's projected power rate can be a complex process. To assist in this effort, please contact John Geib at to determine an estimated rate.

Standard Rates

Schedule SGS (NC) - Schedule SGS is available to nonresidential North Carolina and South Carolina customers that do not qualify for an industrial schedule, and where kilowatt demand is 75 kW or less each month.

Schedule LGS (NC) -Schedule LGS is available to nonresidential North Carolina and South Carolina customers that do not qualify for an industrial schedule where the highest annual kilowatt demand is more than 75 kW.

Schedule I - Schedule I is an industrial service schedule available in both North Carolina and South Carolina to businesses classified as "manufacturing industries" by the Standard Industrial Classification (SIC) Manual (published by the Federal Government) - provided that more than 50 percent of the electric usage is for manufacturing processes.


Time-of-Use Rates

Schedule OPT - Schedule OPT is available for any business and other nonresidential customers. Although this rate varies somewhat in North Carolina and South Carolina, it is intended to encourage a shift of electrical usage from "on-peak" to "off-peak" hours. Charges on these schedules vary according to the time of day, day of week, and season in which energy is used. On-peak and off-peak hours are defined as follows for the summer and winter periods:

June 1 to September 30
October 1 to May 31
Monday to Friday
Monday to Friday
Peak Hours: 1 p.m. to 9 p.m.
Peak Hours: 6 a.m. to 1 p.m.

Rider EC-Economic Development
New business and development in North and South Carolina benefits everyone in the Carolinas in terms of jobs created, regional strength and increased revenues. To encourage economic expansion in our region, Duke Energy Carolinas established the Economic Development (EC) rider. The EC rider provides a four-year billing credit for qualifying projects, beginning (at the customers' discretion) up to 18 months after the initial delivery or expansion of electric service.

This billing credit is applied to your electric bill for new load contracted with Duke Energy. Credits are as follows:

Months 01-12 20%
Months 13-24 15%
Months 25-36 10%
Months 37-48 5%
After Month 48 0%

Rider EC Eligibility
Rider EC is available to new or expanding establishments which:

  • Are billed under Duke Energy's LGS, I, OPT-G, OPT-H or OPT-I rate schedule
  • Add a minimum of 1,000 kilowatts (KW) new load at one delivery point
  • Initiate one of the following:
    • A capital business investment of $400,000 per 1,000 kW of load added, plus a net increase in full-time equivalent (FTE) employees
    • An increase of at least 75 full-time employees per 1000 kW per new load in Duke Energy's service area
  • Agree to a minimum contract term with Duke Energy for 10 years
  • Maintain a monthly average of 250 hours use of electric demand
  • Are not classified as Retail Trade or Public Administration by the Standard Industrial Classification (SIC) manual published by the U.S. Government.

Rider ER-Economic Redevelopment Billing Credit
Rider ER provides qualifying customers locating in Duke Energy-served existing buildings a billing credit of 50 percent for their first year of operation beginning, at the customer's discretion, up to 12 months after the initial delivery of service. The monthly billing credit effectively offers a new customer the opportunity for "half-price energy" during their first year of operation, when they are moving into an existing Duke Energy-served building with adequate Duke Energy electrical service in place.

To qualify for Rider ER, customers must sign a five-year contract with Duke Energy and add a minimum of 500 kW of new load on the Duke Energy system accompanied by either:

  • 35 new full time employees on the Duke Energy system per 500 KW of load,
  • or $200,000 in capital investment per 500 kW of new load with a net increase in full time employees on the Duke Energy system.

Rider ER is available to nonresidential establishments, provided the establishment is not classified as Retail Trade or Public Administration, for load associated with a new customer in an existing establishment served by Duke Energy, provided the establishment has been unoccupied and/or has remained dormant for a minimum period of six months.

Customers must make an application for consideration of Rider ER and must affirm that the availability of this Rider was a factor in their decision to locate the new load on the Duke Energy system. The 500 kW must be at one delivery point, at one voltage and must not result in additional investment in distribution facilities, other than minor alterations in the service which can be accomplished feasibly and economically.
