Canberra will stage one of the largest electric vehicle (EV) vehicle-to-grid (V2G) trials in the world. ARENA has announced $2.4 million in funding towards the ActewAGL to demonstrate V2G services in Australia. The full cost of the trial is $6.6 million.
As batteries on wheels, EVs using V2G technology can discharge electricity back to the grid. The technology is a potential boost to grid security.
The EVs will be part of the ACT Government fleet and will provide Frequency Control Ancillary Services (FCAS) to the National Electricity Market (NEM).
FCAS is used by the Australian Energy Market Operator (AEMO) to maintain the frequency of the electrical system and provide a fast injection or reduction of energy to maintain grid stability.
The trial will involve 50 Nissan LEAF cars, which will return energy to the grid when network demand is high.
Under the trial, the EVs will be used for normal transport operations around the Australian Capital Territory during business hours. They will be plugged into the network when not in use and therefore be available up to 70% of the time to provide grid services such as FCAS.
