Sunrun and PG&E Collaborate on Residential Battery-Powered Virtual Power Plant to Support Grid Reliability for Electric Customers

Rhea-AI Summary

Sunrun and PG&E launched a groundbreaking Energy Efficiency Summer Reliability Program to support residential solar and battery systems in California. Up to 7,500 customers can participate, creating a virtual power plant (VPP) that will generate 30 megawatts of clean energy during peak demand from August to October 2023. Enrolled customers will receive $750 upfront and a free smart thermostat. This initiative aims to enhance grid reliability amid heightened energy demands and offers Sunrun a chance for incremental revenue through its management of the VPP services. The program was prompted by California's efforts to improve energy resilience following a State of Emergency declaration.

First-of-its-kind program will offer financial incentives for up to 7,500 customers in exchange for turning their residential batteries into a collective energy resource during periods of peak demand

SAN FRANCISCO and OAKLAND, Calif., Feb. 06, 2023 (GLOBE NEWSWIRE) -- Following a year of record-high summer temperatures in California, Sunrun (Nasdaq: RUN) and Pacific Gas and Electric Company (PG&E) today launched an innovative energy reliability program to provide meaningful and flexible support from residential solar and battery systems during the state’s hottest months, when demand for energy is highest and energy supplies are tighter.

Through the Energy Efficiency Summer Reliability Program, Sunrun will enroll up to 7,500 new and existing residential home solar and battery systems in PG&E’s service area into the program, creating a virtual power plant capable of discharging 30 megawatts of clean energy back to the grid. PG&E and Sunrun partnered to create an optimal battery dispatch schedule that lowers the overall cost of power during the times of highest need as well as reduces critical strain on the entire energy system and reliance on fossil fuel burning power plants.

A virtual power plant works by storing renewable energy produced by rooftop solar panels during the day across a large number of homes, then sharing that energy back to the grid during peak times, such as at night when the sun has set or when energy supply is tight during hot summer months.

Enrolled battery systems will be directed to discharge every day from 7 p.m. to 9 p.m. during the months of August through October, a critical window when energy needs are highest in California. In exchange, customers will receive an upfront payment of $750 and a free smart thermostat for participating. Batteries enrolled in the program will retain enough energy to meet personal, essential needs in the event of a local power outage in their area.

All Sunrun solar and battery customers in single-family homes who have an interconnection agreement with PG&E, and are not enrolled in other demand response programs, are eligible to participate.

This program will also provide Sunrun incremental revenue for managing and delivering virtual power plant services to the grid for one year, and an opportunity for Sunrun and PG&E to extend and expand the program in future years.

“There’s no denying climate events are becoming more severe and power outages are more frequent and prolonged as a result,” said Mary Powell, CEO of Sunrun. “Consumers want energy security and peace of mind, and by integrating more reliable clean energy resources into the grid through this innovative program, we can deliver that with PG&E. This forward-looking partnership strengthens our emergency preparedness and puts the customer at the center of the energy system.”

“Home batteries and virtual power plants are valuable resources for supporting grid reliability and an essential part of California’s clean energy future,” said Patti Poppe, CEO of PG&E Corporation. “PG&E is making great strides ensuring the grid is ready to partner with a diversity of energy providers. In collaboration with Sunrun, our Energy Efficiency Summer Reliability Program will serve as a unique resource that will positively contribute to our state’s electric grid and complement a host of actions PG&E is taking to provide greater energy resilience to our customers and hometowns.”

This first-of-its-kind partnership was formed after an issuance by the California Public Utilities Commission for “Energy Efficiency Actions to Enhance Summer 2022 and 2023 Electric Reliability,” a direct response to a State of Emergency proclamation issued by California Governor Gavin Newsom. The proclamation challenges energy providers “to take immediate action to reduce the strain on the energy infrastructure, increase energy capacity, and make energy supply more resilient this year to protect the health and safety of Californians.”

The new Sunrun VPP is part of a suite of programs and solutions that PG&E has implemented to decrease energy demand and increase energy supply during critical hours of the day to ensure grid reliability during extreme heat events. This also includes procuring additional energy supply, deploying new incremental battery energy storage capacity, expanding existing Demand Response (DR) programs and incentives, and launching new DR options.

The new Sunrun VPP was approved by the CPUC on January 30, 2023. Sunrun will soon begin enrolling customers into the program and start dispatches on August 1, 2023. PG&E customers interested in participating in the program can purchase or lease a Sunrun home solar and battery system for no up-front cost and low monthly payments at www.sunrun.com.
