Joint Oireachtas Committee on Climate Action

Long-Duration Energy Storage: Discussion

11:00 am

Mr. Brian Kennedy:

We are seeing examples in Great Britain where there is a simpler interaction between behind the meter and the wholesale market, insofar as a group of electric vehicles can combine together into a virtual power plant, trade into the market and, using those signals, find the optimum time to trade or discharge. The approach the Deputy raised is part of the equation. It will not solve the long-duration storage aspect, but it will provide better flexibility to the system and a better demand-side response. In Ireland, it can probably be seen in its earliest stages with the development of the smart meter scheme. I charge my car during the cheapest window. Responding to signals is what that is about. We probably need to see advancements in the ability of the demand side to trade into the market. While that is more a question for the Demand Response Association of Ireland, the association would probably say that we were starting to see movement in that direction.
