The use of submetered data for event performance calculations is permitted for virtual power plant and vehicle-grid-integration aggregators. The use of submetered data will be approved by SDG&E on a case-by-case basis. Aggregators that elect to use submeter data for settlement purposes shall also comply with approved submetering services as outlined in the Aggregator Agreement. The election to utilize submetering will apply to all locations within the aggregation. If the third party is an aggregator, they must provide a single value for each interval, aggregating before sending it to SDG&E for settlement calculations. SDG&E may ask for individual submeter data for pilot Monitoring and Evaluation (M&E) purposes. During the aggregator enrollment process, the aggregator needs to choose if the event performance will be calculated at the SDG&E meter or submeter, which cannot be changed until the next calendar year.
