So, for example, I opened the Halfmoon Bay School solar array recently, and that's performing at 20 percent ahead of the projections for the solar activity you'd get at those latitudes. So we've got more data that we need to learn and that we do need to make sure that we're understanding the full potential, because intermittent renewable sources will definitely be a large part of our decarbonised pathway. But we need to make sure that we have good renewable storage solutions set up there as well.
