Virginia Administrative Code
Title 20. Public Utilities And Telecommunications
Agency 5. State Corporation Commission
Chapter 314. Regulations Governing Interconnection of Small Electrical Generators and Storage
12/22/2024

20VAC5-314-150. Capacity of the small generating facility.

A. If the interconnection request is for an increase in capacity for an existing SGF, the interconnection request shall be evaluated on the basis of the new total capacity of the SGF.

B. If the interconnection request is for a facility that includes multiple energy production or storage devices at a site for which the IC seeks a single point of interconnection, the interconnection request shall be evaluated on the basis of the maximum generating capacity of the facility.

C. The interconnection request shall be evaluated using the maximum capacity that the SGF is capable of injecting into the utility's electric system. However, if the maximum generating capacity that the SGF is capable of injecting into the utility's electric system is limited (e.g., through use of a control system, power relays, or other similar device settings or adjustments), then the IC must obtain the utility's agreement, with such agreement not to be unreasonably withheld, that the manner in which the IC proposes to implement such a limit will not adversely affect the safety and reliability of the utility's system. If the utility does not so agree, then the interconnection request must be withdrawn or revised to specify the maximum capacity that the SGF is capable of injecting into the utility's electric system without such limitations. Nothing in this section shall prevent a utility from considering an output higher than the limited output, if appropriate, when evaluating system protection impacts.
