Vehicle Grid Integration (VGI) aggregators participating in the A.5 Subgroup may elect to use virtual aggregation for some or all the sites in the aggregation when enrolling.
A virtual aggregation permits separately metered EVSE that have a Rule 21 Interconnection Agreement to be aggregated with other load and generation at an electrically contiguous host site. This aggregation will allow export from the EVSE to reduce the host site’s load. Such aggregation will permit an amount up to the sum of the net exports allowed by all available Rule 21 Interconnection Agreements pertaining to the EVSE site and the host site.
Two sites are considered electrically contiguous when they have electric service derived from the same utility distribution transformer secondary and there are no devices on the utility distribution system that can interrupt power flow to only one site.
If you are interested in virtually aggregating electrically-contiguous service accounts, please complete the aggregator enrollment steps and send an email to support@elrp.sce.com stating your interest. The ELRP team will contact you with more information.
