Mr. Jim Gannon:

This is going to go into a level of technical detail where I will need to toss it over the fence to either Mr. Doyle or Mr. Ryan. This relates to an effort to use batteries which might have a shorter duration of a half hour or one hour duration. Normally, we provide that service for system stability to respond to voltage or frequency changes. Now it is a question of looking at these batteries to see how they could effectively be daisy-chained so we have half an hour from one cohort and a further half an hour from another, to cover, for example, for a period of two hours over the winter peak period and to optimise them in that respect, where that is not where they might have served us before. Is that an adequate answer?
