We're looking at it, but I think there's a big question mark next to what the path is, because you could have a number of scenarios. Just to create a distinction, it's not just sort of a transmission generation challenge in the sense of quantity of electricity; part of the bottleneck is also what happens at the distribution level as households themselves take on a different role as energy consumers.
As Niall indicated, it also creates an opportunity, because with that comes storage capacity. I wouldn't want to put a specific number out there. We've looked at relatively modest scenarios, but there are also explosive ones. I think planning-wise it's good to have in mind as a constant right now that the range around those estimates can be quite wide.
