The California utility is working with Rewiring America, Google, Carrier, Tesla, Sunrun, Renew Home, Demand Side Analytics, encoord and other partners to deploy the new VPP in Bay Area communities.
SHARE combines enrollment of existing home energy devices with regional deployment of privately funded new electrification technologies to address growing electric demand.
“This is about delivering power at the speed our economy demands while improving affordability and reliability for the people we serve,” said Chelle Izzi, Chief Commercial Officer, PG&E. “SHARE shows how investing in customers can unlock grid capacity, support growth, and bring real benefits back to communities.”
PG&E is working with Tesla, Sunrun, and Renew Home to enroll nearly 21,000 existing flexible energy devices into the program. This will allow participating households to gain new ways to manage their energy costs and earn rewards for the smart features they already use, while shifting demand during peak periods helping make better use of existing infrastructure, benefiting customers across the region. The resource is expected to begin supporting the grid as early as fall 2026.
“Home energy devices hold enormous, untapped capacity that can meaningfully improve affordability and reliability for all Californians,” said Mary Powell, CEO of Sunrun. “This initiative unlocks that potential while giving customers an opportunity to share in the economic benefits of helping improve their local grid.”
Carrier is the initiative’s launch partner for the new deployments, providing its battery-enabled heat pump solution, including the Carrier Performance Series Variable-Speed Heat Pump with EnerSync, that automatically stores and shifts energy use to help lower costs for customers, maintain comfort and support grid reliability during periods of peak demand.
“As energy demand grows, SHARE demonstrates how Carrier can help deliver distributed capacity with the firmness to scale as a fast and reliable grid resource,” said Hakan Yilmaz, President, Carrier Energy, and Chief Sustainability Officer. “Carrier’s battery-enabled HVAC technology brings together our trusted comfort, market presence and dealer scale to help deliver homeowner value and reliable grid flexibility.”
SHARE reflects a shared commitment to responsible energy growth and is structured so that existing customers benefit from growing grid capacity needs. The program will be fully funded by Google to support customer incentives, technology deployment, and program delivery.
“As demand scales, our current electricity grid can bridge the gap if we optimize it correctly,” said Amanda Peterson Corio, Global Head of Energy & Power at Google. “This program unlocks the potential of local distributed energy resources to strengthen grid capacity and resiliency while delivering meaningful benefits for local communities.”
Rewiring America will work directly with households to deploy and enroll energy-saving electric technologies into SHARE that can serve as flexible grid resources while improving the customer experience. They will also work closely with local installers to ensure projects meet high quality and performance standards.
“This initiative shows how households can be part of the energy solution,” said Ari Matusiak, Founder and CEO of Rewiring America. “By helping families upgrade their homes with efficient electric technologies, we can lower costs, improve comfort, and optimize California’s grid capacity at the same time.”
PG&E will lead planning, analysis, and validation to evaluate customer impacts, system performance and long-term benefits.
PG&E and Rewiring America will begin reaching out to eligible customers starting fall 2026. SHARE is expected to run through 2027, with initial findings from the program expected to be shared in late 2026 or early 2027.
