Net metering is a special metering and billing agreement between Dominion Energy and its customers. The agreement facilitates the connection of renewable energy generation systems to the power grid.
Net metering encourages small-scale renewable energy systems, while ensuring customers always have a reliable source of energy from the grid during times when their renewable generators are not producing energy.
How It Works
Net Metering allows customers to interconnect approved renewable generation systems to the electric grid and provide electricity to their residence or facility. The electricity provided by the renewable generation system offsets electricity that would have been delivered by Dominion Energy.
Benefits of Net Metering
Customers who have a renewable energy generation on their property and sign up for Net Metering will benefit from:
- Producing electricity - You are taking an active role in producing emission-free, renewable electricity for your home, and whatever you don’t use goes back onto the grid.
- Credit for excess generation - When you generate surplus electricity, you will receive credit for each kilowatt hour (kWh) of electricity generated and delivered on the grid.
Eligible Energy Sources
Several types of renewable energy are potentially eligible for net metering:
- Solar energy (photovoltaic)
- Wind energy
- Biomass (landfill gas or methane)
- Hydroelectric power
- Waste heat
- Geothermal energy
- Or any other renewable generation that meets state guidelines.
Maximum renewable generator sizes (AC capacity):
- VA Residential - 20 KW
- VA Non-residential - 1000 kW
- NC All Customer Classes - 1000 kW
Once the final interconnection notification form is approved, the customer’s 12-month net metering period begins. The energy your renewable energy generator produces will offset the energy you would normally purchase from Dominion Energy.
If you generate more electricity than is needed for your home or business in a given billing period, the amount will be used to offset future electricity you would receive from Dominion Energy. The billing period credit is accumulated, carried forward and applied at the first opportunity to any billing periods having positive net consumption. If a credit is generated, the customer still receives a bill each month with basic monthly charges.
How to Apply for Net Metering
Prior to installation:
Step 1: Complete Sections 1 through 4, and sign the Notification form at the bottom.
Note: If you complete the Notification form using the PDF, submit it to Dominion Energy either by scanning and emailing, or mail to:
Dominion Energy Virginia
600 Canal Place, 11th Floor
P.O. Box 26666
Richmond, VA 23261
We will send return confirmation that the Notification form was received.
Step 2: We will review the specifications of the proposed generating system and determine if the system is compatible with the electric distribution grid and the existing electric distribution facilities serving the interconnection point.
When the review is completed, we will return a signed copy of the Notification form along with any additional system protection requirements and/or required upgrades to the existing electric distribution facilities serving the interconnection point to enable completion of the interconnection.
Note: A Net Metering Applicant is solely responsible for compliance with all applicable local zoning requirements, building codes, electrical codes, or any other codes or restrictions governing installation and operation of a generation system. Dominion Energy does not review or approve the system equipment selection, installation method, or installation location. Dominion Energy only reviews the proposed interconnection for compatibility with the electric distribution system, based on UL1741/IEEE1547 standards.
After system installation:
Step 3: Complete Section 5 of the Notification form and resubmit to Dominion Energy . In cases where the applicant or a licensed Virginia Class A or B General Contractor has installed the generation system, a copy of the final electrical inspection signed by the inspection authority may be provided as an alternative to the completion of this section of the Notification form. See the Net Metering FAQs page for additional information.
Step 4: We will complete the required metering work and return a separate written authorization to energize and operate the system.
