Ms Aoife MacEvilly:

What we call utility-scale batteries are being procured through the capacity mechanism. More and more there is a case for smaller scale batteries, almost domestic and business scale, that would probably require a commercial case related to the individual location or site. People with, for example, solar PV may find that it is more beneficial for them to charge a battery and use it at peak times than it is to export, depending on how they are set up and how their business or their home operates. Again, this is probably more the commercial case for the individual location at that level.
