Residential photo voltaic installer Sunrun has partnered with utility Pacific Gasoline and Electrical (PG&E) to enroll photo voltaic and power storage clients in a program referred to as Peak Energy Rewards, which compensates clients for dispatching energy throughout instances of peak demand on the grid.
Sunrun enrolled 8,500 buyer techniques in California, working the belongings as a distributed community that kinds an influence grid. Below this system, the belongings delivered a mean of 27 MW of energy throughout peak hours for over 90 days consecutively.
“PG&E was in a position to confidently depend on the renewing every day useful resource of Sunrun’s fleet of residence photo voltaic and storage techniques,” stated Mary Powell, chief government officer, Sunrun. “We’re quickly transitioning to a storage-first firm and the outcomes of this partnership spotlight the distinctive functionality that distributed energy vegetation present communities.”
The distributed photo voltaic and storage belongings supplied an instantaneous peak output of practically 32 MW and regularly supplied as much as 30 MW of energy, sufficient for greater than 20,000 houses.
Sunrun stated it managed the fleet of residence batteries and supplied energy to PG&E in the identical method a conventional centralized energy plant would. Nonetheless, this system was operational inside six months of signing the contract with the utility, a timeframe that far outpaces the event cycle of utility-scale belongings.
Enrolled batteries within the Peak Energy Rewards program discharged power to the grid from 7 p.m. to 9 p.m. from August by way of October, a time of peak electrical energy demand in California. Prospects obtained an upfront fee of $750 and a free sensible thermostat for collaborating. Sunrun stated that batteries enrolled in this system retain sufficient power to fulfill private, important wants within the occasion of an influence outage.
“Photo voltaic-plus-storage performs a big function in California’s clear power future and we’re happy with our clients who’re main the cost with their clear power adoption. On daily basis, we’re new and higher methods to ship for our hometowns whereas making certain security, reliability and resiliency for our clients,” stated Patti Poppe, chief government officer of PG&E Company.

The utility stated practically 75,000 PG&E clients have linked power storage techniques to its grid, representing 670 MW of capability.
“What is occurring in California will quickly have to be replicated throughout the nation,” stated Powell. “Residential solar-plus-storage techniques networked collectively as distributed energy vegetation are answering the demand name by offering versatile, on-demand energy stabilization whereas additionally guarding towards rising charges.”
Regardless of including new worth to clients by way of battery aggregation applications, residential photo voltaic installers in California have been confronted with elevated challenges to buying new clients. Excessive rates of interest have worsened the return on funding for patrons, and the transfer towards NEM 3.0 has altered the worth of exported electrical energy. The California Photo voltaic and Storage Affiliation advisable coverage adjustments to enhance market situations and revive the state’s wounded behind-the-meter photo voltaic business.
