Sunrun is working with your Community Choice Aggregator (CCA) - Peninsula Clean Energy (PCE) - to use a fleet of Sunrun Brightbox systems to help create a more reliable, renewable and cost-effective energy system in Northern California.
At times when there is high demand on the local electric distribution system (i.e. the “grid”) or during other critical periods, your Brightbox will respond with support by sending energy from your battery to the grid. This coordinated discharge of your and your neighbors’ Brightboxes will occur in the afternoons during the Time of Use (TOU) hours when your energy prices are highest. This means that while there may be a slight change in the battery’s operation during a grid services event, you will retain the highest value from your system’s discharge.
By using the Brightbox energy storage systems in this manner we will improve grid resilience, drive down costs for all customers by avoiding expensive infrastructure upgrades, and ultimately allow for deployment of more carbon-free solar energy and battery storage to the grid.
