Today’s energy grid is changing quickly. As more and more customers demand access to clean energy and new technology, policymakers, regulators, and grid managers are rethinking the infrastructure and markets that connect us with the power we use every day. This change means a new set of opportunities for collaboration between utilities and solution providers like Sunrun — a chance to work together to build a cleaner, more resilient energy system while delighting our shared customers.
How Solar + Brightbox Works
Grid services for wholesale power markets and locational needs
Sunrun's full suite of grid services capabilities can be customized to meet grid managers' planning and operational needs. By aggregating Brightbox behind-the-meter solar and battery energy storage assets, we can provide capacity products, voltage support, and more.
Manage system peaks with distributed solar - Sunrun's Brightbox systems can ensure distributed solar capacity provides optimized value for the grid. Brightbox uses rooftop solar power to charge home batteries when on-premises demand is low, reducing midday solar injections. The batteries can then be discharged to reduce system ramp or shave system peak as demand increases, creating a resource to help fight the "duck curve".
Leverage demand response capabilities of distributed solar and batteries - Sunrun can discharge fleets of home batteries when called by our utility or transmission system operator partners to offset net customer load, deliver system capacity, and lower wholesale power costs.
Increase voltage support in constrained grid areas - Brightbox can deliver reactive power in response to grid needs, maintaining power quality and grid reliability in locations with high concentrations of distributed energy resources.
Industry-leading customer experience
Sunrun pioneered solar as a service in 2007, and is committed to providing exceptional service to our customers and partners. We maintain an A+ rating with the Better Business Bureau, with industry-leading customer satisfaction ratings. We form long-term partnerships with our customers, ensuring their solar and Brightbox battery systems perform as guaranteed during the life of a typical 20 to 25-year solar-as-a-service agreement. We partner with utilities to enable these assets to respond to grid needs for the duration of this multi-decade customer relationship.
Partnerships for grid value and customer success
In collaboration with grid managers, we can deploy Brightbox battery systems where they will add the most value for utilities, the grid, and customers. We are actively delivering Demand Response and capacity services to meet operational needs in multiple geographies, and partnering with grid managers to build a more resilient electricity system that integrates the new energy technologies customers want.
Together, we can develop and launch:
Bring-Your-Own-Device Programs to connect customers with energy technology and choice, while allowing our partners to leverage the full technical capacity of Brightbox and other new energy resources.
Virtual Power Plants to integrate diverse resources into common operational assets for managing load, reducing system peaks, and building resiliency at the local level.
Non-Wires Alternatives to reduce system upgrade costs while providing critical grid planning and operational capabilities.
In partnership with National Grid, Sunrun is delivering Demand Response for annual peak reduction via the ConnectedSolutions program in Massachusetts.
Building on our utility Demand Response partnerships, Sunrun is now participating in ISO NE's Forward Capacity market - a first for Behind the Meter resources. Read more here.
Sunrun has installed more than 1.5 gigawatts of home solar for more than a quarter of a million customers, with thousands of households nationwide choosing our Brightbox solar and battery product. Sunrun is ready to work with our partners to deploy these systems with precision, when and where they will create the greatest grid benefit.
