Kerala V2G Pilot: KSEB and IIT Bombay Test Grid Support
Why in the news
Kerala’s power utility and IIT Bombay teamed up to test whether electric vehicles can back up the state’s grid, especially at evening peaks.
Key facts
- V2G enables EV batteries to discharge into the grid when idle; power flows both ways (G2V and V2G).
- EVs act as mobile storage, helping peak load management, demand response and renewable integration.
- Related uses: V2H (home) and V2V (vehicle); V2G is the most pursued.
- Kerala’s problem: rapid EV and rooftop solar growth, evening demand spikes and solar generation that peaks by day.
- Pilot goals: gauge EV support at peak hours, offset evening demand, and lay a base for V2G infrastructure in distribution networks.
Global and Indian picture
| Place | Situation |
|---|---|
| Europe and US | Owners are paid to feed power back at peak times |
| UK and Netherlands | EVs supply surplus battery power in high demand |
| California | EV users join ancillary services |
| India | Early stage; focus on charging; some DISCOMs trial smart charging and V2G; CEA drafting reverse charging guidelines |
Concerns
- Market structure does not favour decentralised energy sharing.
- Grid variability, renewable mismatches and thin regulatory support.
- Needs reforms, tariff mechanisms and smart grid investment.
Exam angle
- Pilot partners: KSEB and IIT Bombay.
