Mr. Rodney Doyle:

I am happy to come in on these questions. If an entity does not participate when asked, we have metering at all of the sites. We can, therefore, see exactly what is being provided by any particular unit. We can determine if they have provided what we have requested. We can follow through and follow up on that after the event. Regarding what each individual unit gets paid for any particular event, if we have a demand reduction and a tightness of the system, they would not get paid where we have to intervene to ask them to reduce their demand during that period. That is an intervention that we are making in the market. If they offer up their demands into the system by being part of what is called a demand side unit, DSU, which a number of them do, they are remunerated by being paid the price prevailing in the market at that point in time. This is the same as with any other generator. There are entities that aggregate a number of demand sites and then bid it into the electricity market. We would then dispatch them in the same way that we would another generator in the electricity market. They would get paid the prevailing price. It depends upon how they participate in the market itself.
