Mr. Dermot Nolan:

On the first comment, I must stress again that we do not actually set the price of retail electricity. Competing entities and consumers have a choice between them. In answer to the question on renewable and nuclear energy, there is probably a small element of nuclear energy coming in under the new east-west interconnector from the UK. It is probably not very much, simply because the use of nuclear energy by the UK has fallen considerably in the last five years. There is some coming in, but it is not a huge amount in terms of affecting the price here. There is not enough interconnection. The interconnector is valuable for all kinds of reasons but the nuclear energy does not have a huge effect.

Renewable energy is a very controversial and interesting area. Without going into too much detail, nearly 17% of our electricity comes from wind energy, and that proportion will rise considerably over the next seven or eight years. By and large, when the wind blows it is nearly free, so that drives down the price a lot. On the other hand, perhaps two thirds or even 70% of the time, the wind does not blow so it has no effect. The overall average affect of that depends on what the price of gas would have been. If gas or coal prices are very high, then renewable energy will lower the price. If gas prices are very low, then renewable energy may actually raise the price somewhat. There is that sort of trade off and it will really depend on fossil fuel prices generally. The public service obligation, or PSO, is set by government policy but the CER calculates it every year. A proportion of that - perhaps 2.5% of the entire electricity bill - goes on supports for renewable energy, so that is also a factor.

I will pass on to my colleague to deal with the other queries, bar the networks and water.
