Google funds PG&E's grid-stabilizing energy program

PG&E's SHARE initiative, fully funded by Google through 2027, tests distributed energy capacity to improve grid reliability and lower consumer costs.

PG&E launched its SHARE virtual power plant program in September 2026 as a proof-of-concept for privately funded distributed energy. Google provides full funding through 2027, enabling enrollment of nearly 21,000 residential flexible energy devices via partners including Tesla, Sunrun, and Renew Home. The program targets unlocking 17 GW of potential flexible energy capacity nationwide, with California accounting for 4.7 GW—75% batteries and 25% thermostats. SHARE aims to enhance grid stability and reduce consumer electricity costs through this distributed approach.

The mechanism relies on existing residential assets: flexible thermostats and home batteries that can dynamically adjust energy use. By aggregating these resources, SHARE creates grid resilience without new infrastructure. This model could scale to commercial, industrial, and utility-scale assets if future development occurs.

For consumers, SHARE’s potential to lower electricity costs through grid optimization represents a direct path toward cheaper energy access. However, as a proof-of-concept limited to residential devices, it hasn’t yet shipped at scale. The program’s next phase—initial findings by late 2026 or early 2027—will determine whether distributed energy can reliably reduce costs for households without expanding the grid. Current friction includes the program’s restriction to residential assets and the 17 GW figure representing potential capacity, not current deployment.
