Grid Services · CA VGI
California's VGI programs fund managed charging, V2G (vehicle-to-grid), and V2X (vehicle-to-everything) projects — combining upfront grants with ongoing grid services revenue.
Quick Answer
California Vehicle-Grid Integration (VGI) programs fund bidirectional and managed EV charging through CPUC and utility pilots. Participants receive upfront equipment funding plus ongoing grid services revenue (demand response, frequency regulation, capacity).
State
Varies — bidirectional pilot programs typically $5K–$50K per vehicle/charger
Pilot program funding + ongoing revenue
Pilot enrollment 1–6 months
Vehicle-Grid Integration (VGI) is California's umbrella term for smart charging programs that use EVs as flexible grid resources. CPUC and the three IOUs (PG&E, SCE, SDG&E) run multiple VGI pilots covering managed charging, V2G, and V2X applications.
Unlike traditional EV charger grants, VGI programs combine upfront funding (for the bidirectional chargers and software) with ongoing revenue streams from demand response participation, frequency regulation, and capacity payments.
VGI is most lucrative for fleet operators (school buses, delivery vans, transit) where vehicles are predictably parked and connected during off-peak hours. Multifamily and workplace sites with managed charging also qualify for ongoing rate incentives.

Estimated timeline: Pilot enrollment 1–6 months
PG&E, SCE, and SDG&E each run distinct VGI pilots. Identify which matches your project type (school bus V2G, fleet managed charging, workplace V1G, etc.).
VGI requires bidirectional or managed-charging-capable equipment with grid services APIs (OCPP 2.0.1+, OpenADR). Verify equipment compatibility before committing.
Submit pilot enrollment with site information, fleet/charger inventory, and participation commitment.
Connect chargers and vehicles to the utility's dispatch platform or a third-party aggregator.
Once enrolled, participate in demand response, frequency regulation, or capacity events. Earn ongoing revenue based on availability and dispatched capacity.
VGI revenue depends on consistent availability. Monitor performance dashboards and maintain >95% availability for full revenue capture.
VGI funding is generally stackable with traditional EV charger programs (CALeVIP, utility make-ready, 30C) — the bidirectional equipment qualifies for those programs too. Ongoing grid services revenue is independent of upfront grants.
