Project Summary

This project builds upon an operational FirmPV installation in San Francisco, which is a combination of Tesla Motors' vehicle battery system with SolarCity's SolarGuard dispatch and monitoring platform. The ability to firm intermittent renewable resources will likely result in peak demand reductions and system-wide grid network benefits. The SolarCity team conducted demonstrations at 9 sites to assess system performance along with assessing the economic, reliability, and carbon reduction impacts of large-scale deployment of a FirmPV product. Additional tasks included conducting analysis to determine an optimal tariff product or rate plan that will provide the benefits of FirmPV at the lowest overall cost. Lastly, the SolarCity team explored a range of financing mechanisms that will best enable FirmPV deployment.
