(1) There is currently very limited availability in Australia of Vehicle to Grid (V2G) capable vehicles and charging systems. The vast majority of EVs available in the NSW market today use a CCS2 (Combined Charging System, Combo 2) charging plug. Global standards are still under development to enable bidirectional charging for EVs using this plug.
There is some concern that national inverter standards do not currently clearly allow for V2G charger connections to the electricity network.
(2) The NSW Government is engaging with other states and territories to facilitate grid integration of electric vehicles through the Energy and Climate Change Ministerial Council (ECMC), including through identifying and pursuing appropriate regulatory reforms. Grid integration includes bidirectional charging.
(3) The NSW Government does not prohibit or prevent the approval of network connections for bidirectional EV chargers. This is for the consideration of NSW's Distributed Network Service Providers.
(4) In addition to work under the ECMC (see response to question 2), the NSW Peak Demand Reduction Scheme is intended to incentivise V2G bidirectional charging when the technology becomes more available. This will require the development of related rules under the scheme.
