Initially, the energy startup Base Power introduced a business model centered on its ‘Base Core’ home battery system. By managing charging and discharging cycles, the company integrates customer batteries into a distributed VPP to feed electricity back into the grid during peak demand, offering lower electricity rates and emergency backup power. Following this, a broader collaborative effort emerged in California through the ‘Smart Home Assets for Reliability and Efficiency’ (SHARE) program. This initiative involves a coalition including Google, Tesla, Sunrun, and Pacific Gas and Electric (PG&E). The program utilizes home battery storage, smart devices, and heat pumps to create grid capacity and support reliability in Santa Clara and Alameda counties. ## Timeline ### 2026-09-07: Google and Tesla partner with PG&E on California virtual power plant Google, Tesla, Sunrun, and PG&E are launching the SHARE virtual power plant in California to manage peak energy demand using home batteries, smart devices, and heat pumps. 2 sources. https://clstr.news/cluster/google-and-tesla-partner-with-pge-on-california-virtual-power-plant ### 2026-08-09: Base Power launches home battery and virtual power plant service US startup Base Power is integrating home batteries into a virtual power plant, offering customers backup power and lower electricity rates by managing energy distribution to the grid. 2 sources. https://clstr.news/cluster/base-power-launches-home-battery-and-virtual-power-plant-service --- Cite as: US virtual power plant technology development.
