Eligible Renewable/Other Technologies:
NOTE: The omnibus energy bill enacted in March 2018, S.B. 966, includes an enactment clause requiring utilities to investigate potential improvements to the state’s net metering and community solar programs. Each utility will hold stakeholder meetings for the development of proposed legislation. As of Q4 2018, the proceeding is ongoing.
Net metering in Virginia is available on a first-come, first-served basis until the rated generating capacity owned and operated by customer-generators reaches 1% of an electric distribution company's adjusted Virginia peak-load forecast for the previous year. Net metering is available to customers of investor-owned utilities (including competitive suppliers) and electric cooperatives, but not to customers of municipal utilities.
Virginia's net-metering law applies to electric customers who generate electricity from renewable fuel sources* that are up to 20 kilowatts (kW) capacity for residential customers and 1,000 kW in capacity for non-residential customers. The generation systems must be located on the customer’s property and must be sized to primarily offset the customer’s electricity requirements. Systems installed after July 1, 2015 shall not exceed the expected annual energy consumption based on 12 month of billing history or annualized calculation if the billing history is not available.
After July 2019, all eligible agricultural customer-generators will be able to interconnect only as “small agricultural generators”. Small agricultural generators will be credited through a buy-all, sell-all arrangement at a non-retail rate.
Prospective net metering customers must receive approval to interconnect from their electric supplier prior to installation of the generation system. The electric distribution company must notify within 30 days if the customer meets the requirements for net metering. The net metering application is considered automatically approved if the electric company fails to notify within 30 days for residential customers and 60 days for non-residential customers.
HB 1983 that was passed in March 2011, requires that residential facilities with an AC capacity of greater than 10kW must pay a monthly standby charge. The amount of standby charge will be developed by the electric supplier and be approved by the Commission after it determines that the charge is reasonable to allow the supplier to recover portion of the infrastructure cost. The customers must also pay inspection fee of $50 for inverter based systems greater than 10 kW.
Any residential net-metering customer of Dominion Virginia Power who owns and operates, or contracts to own and operate, an electric generation system with a capacity greater than 10kW and less than 20kW is required to pay transmission and distribution standby charges. Customers will be required to pay $2.79 per kW in monthly distribution standby charges and $1.40 kW in monthly transmission standby charges. The SCC denied Dominion's proposal for generation standby charges, but Dominion may reapply for approval for these charges in the future.
Net Excess Generation:
Net-metered energy is measured by a meter capable of gauging electricity flow in both directions. Monthly net excess generation (NEG) is carried forward to the next month. At the end of each 12-month period, the customer has the option of carrying forward eligible excess NEG to the next net metering 12-month period or selling the NEG to the utility. The amount of credit to be carried forward to a subsequent net metering period may not exceed the amount of energy purchased during the previous annual period.** In the case of selling the NEG to the utility, the customer must submit a written request to establish a power purchase agreement with the utility prior to the beginning of the net metering period to be covered by the power purchase agreement. The investor-owned utility must pay avoided cost (or higher if agreed upon). Net metering is also available to customers on time-of-use tariffs (with time-of-use applicable NEG calculations).
Legislation adopted in 2018 requires Dominion to conduct a pilot program to provide compensation to any school that generates excess electricity from wind or solar on an annual basis. As of Q4 2018, Commission is reviewing the draft guidelines filed by Dominion.
In 2013, HB 1695 created net metering programs for agricultural customers of investor-owned utilities and electric cooperatives. Agricultural customers are allowed to aggregate their electric meters in a single account such that they are located at contiguous sites and served under an appropriate tariff. The aggregated generation capacity is limited to 500 kW for agricultural businesses.
HB. 1451 enacted in March 2018, directs Dominion Energy to conduct a pilot program under which a public school that generates more electricity from a wind-powered or solar-powered renewable energy generation facility than it consumes at the option of the school board may either credit the excess electricity to one or more other schools in the school division or be paid for the excess electricity at the contractually negotiated rate. The duration of the pilot program shall be six years.
Community Solar Pilot Program
S.B. 1393 enacted in March 2017, required the state's two investor owned utilities- Dominion Virgina and Appalachian Power- to develop community solar pilot programs for their retail customers. The community solar projects must i) exclusively use solar ii) be placed in service on or after July 1, 2017, iii) not constructed by the utility, but acquired through a purchase agreement from a third party, and iv) sized no larger than 2 MW per project. The pilot program has a duration of three years. Appalachian Power must have program between 0.5 MW and 10 MW, while Dominion's program must be between 10 MW and 40 MW. The program design and the voluntary rate schedule for participants in the community solar programs will be approved by the Commission.
As of Q4 2018, the final program design of the community solar program has not been approved but is expected to be approved soon. Please check Dominion website for timely updates.
Customer-generators own all of the renewable energy credits (RECs) their system generates. Virginia's net metering law states that at the time a customer enters into a power purchase agreement with the utility for net excess generation, the customer has a one-time option to sell RECs to the utility. This provision does not preclude the customer and utility (or other entity) from voluntarily entering into an agreement for the sale and purchase of RECs at any other time.
*According to the VA statutes § 56-576 renewable energy includes energy derived from sunlight, wind, falling water, biomass, sustainable or otherwise, energy from waste, landfill gas, municipal solid waste, wave motion, tides, and geothermal power. It also includes proportion of thermal or electric energy from a facility that results from co-firing of biomass
**For example, if a customer-generator bought 1,500 kilowatt-hours (kWh) from a utility during the first 11 months of the annual period, and then generated 2,000 kWh of excess electricity in the12th month, the customer could carry forward 1,500 kWh to the following month, and the remaining 500 kWh would be granted to the utility.
