Growth / Incentives Options

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 SGS, LGS, G, GA or OPT rate
  • 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% 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 in an existing Duke Energy-served building with adequate Duke Energy electrical service in place, the opportunity for 'half price energy' during their first year of operation.

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.
