What we also know is that—and moving on to another question that was asked around solar—it's actually dry-year storage that will unlock the real potential of some of our more intermittent renewable sources, such as wind and solar, in New Zealand. The fact that we can have that ability to release from a pumped hydro system will mean that we can see more of an uptake in wind and solar. Wind is a very proven technology in New Zealand. I don't think we have enough data on solar and the potential in a number of permutations, and that is exactly why we have invested the $28 million into getting data through trials on our Māori housing and our public housing stock. Some of it will be stored in batteries, some of it will go direct to hot water, some of it will be a solar array that generates for a community rather than individual houses, but I do note that we're still learning a lot about different capacities for solar at different latitudes in New Zealand.
