What is Parallel Generation?

"Parallel generation" refers to a generator that produces electricity while it is connected to the electric grid. Your electrician or consultant can tell you whether your generator will operate in parallel.

Generator Interconnection

You'll need permission to interconnect your parallel generator to Dominion Energy’s electric grid. Interconnections must be individually accepted and inspected prior to beginning parallel operation.

There are several options available for interconnecting your parallel generator, including net metering or selling the generator output. Specific requirements will vary depending on whether your project is located in Virginia or North Carolina and whether it is a distribution or transmission interconnection.

Other Resources

Please see the Frequently Asked Questions (FAQ) for definitions and additional information about interconnection options.

Overview – Interconnection Steps provides a listing of the basic steps for interconnecting your generator.

For electric service, please consult Dominion Energy’s Blue Book - Information and Requirements. Section 190 of the Blue Book has information regarding customer generation.

Download the Interconnection Request Application to get started.

Net Metering

If your generator is fueled entirely by renewable energy, you may be able to sign up for net metering, where any power in excess of what you consume is fed back to the electric grid to offset future consumption.

To learn more visit the Net Metering homepage.

Interconnection Under Federal Jurisdiction

Many interconnections to our distribution system involve federal jurisdiction. Since all requests involving federal jurisdiction are processed by PJM Interconnection, you should initially contact PJM about your request.

Depending upon the characteristics of your interconnection, PJM will either process your request or suggest that you contact us to process your request under state jurisdiction. PJM Interconnection is the regional transmission organization (RTO) that administers many of the interconnections to Dominion Energy’s system in accordance with the PJM Open Access Transmission Tariff(OATT).

You can learn more about PJM Generator Interconnection Procedures on the PJM website.

Interconnections to Dominion Energy’s transmission system must also comply with our Facility Connection Requirements. Additional information about Dominion Energy’s electric transmission system including PJM OATT, informational postings/notices required by Federal mandates, and electric transmission planning and statistics are available on the Electric Transmission web page.

Dominion Energy North Carolina

The North Carolina Interconnection Standards provide information, application forms, and requirements for interconnection and parallel operation of customer-owned generating facilities in North Carolina. The North Carolina Interconnection Standard is attached to Section XXIV of Dominion Energy North Carolina’s Terms and Conditions.
