Episode notes
EVs Stabilize Grid During Coal Plant Failure
- In February 2024, a major Victorian coal plant failed, causing grid instability.
- 16 Nissan Leaf EVs in the ACT, 500km away, successfully injected power back into the grid, marking a world first.
V2G Technology and Compatibility
- V2G technology currently relies on CHAdeMO, limiting compatible EVs.
- The 2025 CCS standard update will enable V2G for most EVs, pending charger availability.
Potential of EVs for Grid Support
- During the Victorian grid event, 16 EVs provided 107 kW of power, a small but promising contribution.
- 105,000 EVs could potentially provide all frequency reserves for the NSW-ACT grid.
