Vehicle-to-Grid (V2G) Aggregator
A vehicle-to-grid aggregator coordinates electric vehicle fleets to discharge power back to the grid or reduce charging load in response to price signals. Aggregators enroll fleets, install bidirectional chargers, manage telemetry, and participate in demand response, ancillary service, or distribution flexibility markets.
V2G platforms forecast fleet availability, state of charge, and mobility requirements so that grid services do not disrupt transportation. They integrate with DERMS and ISO market interfaces, translating dispatch commands into charger-level instructions.
Revenue streams include capacity payments, fast frequency response, congestion relief, and demand charge savings for fleet operators. Regulators are beginning to standardize interconnection and metering rules for bidirectional chargers, expanding market participation.
Investors evaluate V2G aggregators based on charger partnerships, customer acquisition, communication protocols, and the ability to provide warranties that cover battery degradation costs.
Technical Details
- •Requires bidirectional chargers compliant with IEEE 1547 and ISO 15118 standards
- •Aggregates telemetry and dispatch signals across fleets
- •Participates in demand response, ancillary services, and flexibility markets
- •Needs algorithms to respect mobility schedules and battery health
- •Often paired with fleet management software and demand charge optimization
Why It Matters
V2G unlocks a scalable source of flexible capacity that supports both distribution and wholesale reliability needs. Tera tracks V2G pilots, tariffs, and aggregator partnerships so fleet operators and investors can benchmark revenue potential.
