 Thank you, Andy. So, I just advance this. As Andy said, I'm the director of the energy centre and I thought I'd just give you a sense of what we're about in the energy centre. The energy centre is very problem-focused. So, we like to approach so-called real-world problems. We like to inform our outputs with good research and importantly, it's cost-disciplinary. So, every research project that I've been involved in since being director of the energy centre has involved cross-discipline. So, they'll come from engineering, science, arts, and actually, Nikai some years ago too. So, it's very cross-disciplinary. That's what spins my wheels, gets me out of bed in the morning. And what we try to do, we try to inspire first of all and we do that through our publications obviously. And we run a summer school on energy economics that's open for a week, no charge to anybody that's interested in energy. Involve people, cross-disciplinary. Try to influence the community, public policy and so on. And impact, that's the hardest thing as most of us researchers know is actually describing the impact of your research. But that's basically what we try to do. I just want to mention, talk very briefly about renewables, the work that we're doing on renewables. The NZ Government set a target of 90% by 2025 here. Currently, it's sitting around 80%. And you can see that most of our electricity is generated by hydro resources. And we are very fortunate in New Zealand in having a hydro legacy. A lot of this development occurred in the 1960s, 1970s. Is the 90% feasible? Yes, it is. Our research has shown that it's quite feasible to hit the target of 90% renewables by 2025. And this will come primarily from geothermal wind and solar developments and, of course, hydro, which is already in place. We will not see much large-scale hydro development in New Zealand in the future here. Turning to wind and hydro, this was a problem that the NZ Wind Association asked us to have a look at. And basically, given that we have a high dependency on hydro, the interesting question is whether or not there is some kind of correlation between when the wind is blowing. New Zealand has one of the best wind resources in the world. Our load factors are around 45%. So they're generating electricity about 45% of the time. The problem that we have in New Zealand is that, typically, when the wind is blowing, the water is not flowing into our hydros. So it's not an ideal situation here. The other interesting... I'm sorry, I've made a bit of a mess of that slide there, but wind is a low-cost source of electricity. And so the interesting question then is, does wind-generated electricity have a depressing effect on the wholesale price of electricity? And if you look at these images here, you can see here, so you can't read that, that is the injection price, the wholesale price of electricity here, and the green one is the wind generation. So when the wind is blowing here, our injection, our price is at the nodes throughout New Zealand are low. And that's what we see throughout the country. So when these wind farms are pumping electricity into the system here, typically prices are relatively lower. And when the wind is not blowing, you can see the opposite effect here. You get spikes in electricity prices. And so the answer to that question is yes. By generation type, we see these are all statistical levels of significance here. Wind keeps a negative impact on price. Hydro and thermal plants, as you'd expect thermal, coal previously and gas here, that's going to put upward pressure on prices. Geothermal was not significant. Okay. And the other interesting question they had was whether or not these nodes are connected to one another, or they're obviously connected, but does wind entering at one particular node have a spillover effect on other nodes throughout the country? And we're able to address that question yet directly there using econometric techniques. And it raises the question of where are the best sites for locating our wind farms. A more recent study that we've just initiated is looking at the solar potential for Auckland City, and we collaborated with Auckland Council to get their lidar data there, which is so you've got impulses that come down from the plane in this case here, but they could be drones or whatever. And you can build 3D models of the surface here. And so we're able to capture that and look at the solar potential for different suburbs throughout Auckland here. So this is Mt Eden here versus Pukekoe here, and you can see the red here illustrating that Pukekoe houses have got a greater potential than the houses in the Mt Eden area. So that's a work that we initiated at the beginning of last year, and it's still ongoing here. And so it raises the question of investment in solar here. Currently solar potential has increased from about 5 megawatts to 35 megawatts in 2016, so we're going to see an increase in this here. The levelised cost, so this is a cost of actually recovering your investment and obviously maintenance costs and so on over the life of the system here. It's about 30 cents per kilowatt hour, which is slightly over the price that you pay for electricity. Next steps here, we're working with Māori River Power to develop an app to enable consumers or households to look at that based upon the images that we can produce and the potential that we can illustrate here whether or not it's worth their while investing in solar and and also one other future challenge here is that the invent of solar is going to create really big challenges for the local distributors such as Vector because when people are feeding electricity into the grid they're actually using their resource and so there's issues around market design. So, thank you very much.
