Parallel Generation & Interconnection
How to apply for parallel generation and interconnection to the distribution system
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 the state in which your project is located and whether it is a distribution or transmission interconnection.
