Residential solar installer Sunrun has actually partnered with energy Pacific Gas and Electric (PG&E) to register solar and energy storage clients in a program called Peak Power Rewards, which compensates clients for dispatching power throughout times of peak need on the grid.
Sunrun registered 8,500 client systems in California, running the possessions as a dispersed network that forms a power grid. Under the program, the properties provided approximately 27 MW of power throughout peak hours for over 90 days consecutively.
“PG&E had the ability to with confidence depend on the restoring everyday resource of Sunrun’s fleet of home solar and storage systems,” stated Mary Powell, president, Sunrun. “We are quickly transitioning to a storage-first business and the outcomes of this collaboration emphasize the special ability that dispersed power plants supply neighborhoods.”
The dispersed solar and storage possessions supplied an instant peak output of almost 32 MW and often supplied approximately 30 MW of power, enough for more than 20,000 homes.
Sunrun stated it handled the fleet of home batteries and supplied power to PG&E in the exact same method a standard central power plant would. The program was functional within 6 months of signing the agreement with the energy, a timeframe that far surpasses the advancement cycle of utility-scale properties.
Enrolled batteries in the Peak Power Rewards program released energy to the grid from 7 p.m. to 9 p.m. from August through October, a time of peak electrical energy need in California. Clients got an in advance payment of $750 and a complimentary clever thermostat for taking part. Sunrun stated that batteries registered in the program keep enough energy to fulfill individual, vital requirements in case of a power blackout.

“Solar-plus-storage plays a considerable function in California’s tidy energy future and we’re happy of our consumers who are leading the charge with their tidy energy adoption. Every day, we’re taking a look at brand-new and much better methods to provide for our home towns while making sure security, dependability and resiliency for our clients,” stated Patti Poppe, president of PG&E Corporation.
PG&E has the most behind-the-meter solar setups in the country connected to its grid, with roughly 820,000 clients linked including approximately 8 GW of capability to the grid. The energy stated almost 75,000 PG&E consumers have actually linked energy storage systems to its grid, representing 670 MW of capability.
“What is occurring in California will quickly require to be reproduced throughout the nation,” stated Powell. “Residential solar-plus-storage systems networked together as dispersed power plants are responding to the need call by supplying versatile, on-demand power stabilization while likewise defending against increasing rates.”
In spite of including brand-new worth to consumers through battery aggregation programs, domestic solar installers in California have actually been confronted with increased obstacles to obtaining brand-new consumers. High rates of interest have actually aggravated the roi for consumers, and the approach NEM 3.0 has actually modified the worth of exported electrical power. The California Solar and Storage Association advised policy modifications to enhance market conditions and restore the state’s injured behind-the-meter solar market.
