Coordinated Holistic Orchestration of Inverter-based Resources (CHOIR)
The California Energy Commission is funding demonstrations of virtual power plants coordinating solar PV, battery storage, and EV charging across multiple distribution circuits to manage power quality and grid congestion without fossil fuel peaking units. Projects will operate at scale in real utility networks, proving VPP software and controls can handle high concentrations of inverter-based resources in electrified load areas.

AI overview
This solicitation aims to demonstrate and advance the capabilities of virtual power plants (VPPs) that coordinate high concentrations of inverter-based distributed energy resources (IBDERs) – such as solar photovoltaics (PV), battery energy storage systems (BESS), and electric vehicles (EV) – to provide distribution-level power quality services, alleviate grid congestion due to electrification growth, and reduce reliance on fossil fuels. The program seeks to fund projects that will advance VPP technology and demonstrate its effectiveness in managing distributed energy resources at scale.
