Mr. Brendan Tuohy:

One is balancing two things here - what happens on the adequacy of supply and security of supply. The one thing one does not want when doing this is for the system to collapse. Nobody wants that.

We are out on what is called the system non-synchronous penetration rate in Ireland. We are world leaders at 65%. That is the instantaneous amount of non-synchronous, non-traditional wind, etc., on the system. We are up, with Australia, at No. 1 on that. There is no question that we will move that but one must distinguish between the instantaneous and the long term. When one is building out a system like this one will have renewables on top of it but at present I cannot see a situation where one will have all renewables because one will not have the level of certainty in the system.
