Ms Marguerite Sayers:

It is not something that ESB ecars has been involved in. There are several trials that other parts of the ESB have been engaged in. The same applies to other countries. If there are 1 million or even 500,000 EVs, each with a 70 kW battery, there is massive potential for storing renewable energy or providing ancillary services to the grid when there are interruptions in frequency, etc., but it is quite nascent. It is all at the trial stage so I feel having a concrete system is something that will happen in the future rather than at present. We will continue to investigate and do trials. Some cars are not capable of having a bidirectional flow so it is a matter that will be addressed over time by the manufacturers. It is quite immature at present.
