V2G (Vehicle-to-Grid)

Technology that enables electric vehicles to discharge stored energy back to the electricity grid, supporting grid stability and creating revenue opportunities for EV owners.

What is V2G?

Vehicle-to-Grid (V2G) is bidirectional charging technology that allows electric vehicles (EVs) to not only draw power from the grid but also return stored energy back when needed. This transforms EVs from simple consumers into mobile energy storage assets that can support grid stability.

V2G systems require compatible chargers, vehicles, and grid connections to enable the two-way flow of electricity.

How V2G Works

The V2G process involves several components:

  1. Bidirectional Charger - Special charging equipment capable of both charging and discharging
  2. V2G-Enabled Vehicle - An EV with hardware and software supporting bidirectional power flow
  3. Smart Metering - SMETS2 meters to accurately record energy flows in both directions
  4. Grid Connection - Appropriate DNO agreements for export capability

Benefits of V2G

V2G technology offers advantages for multiple stakeholders:

  • Grid Operators: Access to distributed energy storage for peak demand management
  • EV Owners: Revenue from selling stored energy during high-price periods
  • Renewable Integration: Buffer intermittent solar and wind generation
  • Emergency Backup: EVs can provide power during outages

V2G and SIP Accreditation

As V2G becomes mainstream, SIP-accredited organisations will play a key role in:

  • Installing and commissioning bidirectional charging systems
  • Managing the safe isolation of grid connections
  • Handling market messaging for energy export flows
  • Ensuring compliance with evolving regulations

Our SIP accreditation services prepare your organisation for V2G opportunities with the necessary certifications and system integrations.
