Mr. Jim Gannon:

I will take the questions. I will take questions one, two and four and pass over to one of my colleagues to comment on diversity or security of supply for our gas, if I can put it that way.

The first question speaks to the existing capacity of thermal plants that are responding but are finding it difficult to respond to wind intermittency. It is a natural thing that our grid generation fleet has to contend with. We have described clearly that some of the older fleet will need to be replaced by quick-responding kit that has been designed for this purpose. We expect that will be predominately gas fuelled.
