Therefore, if you buy, you know, a fossil fuel - powered replacement now, then you're actually going to be stuck with a really expensive liability within, say, 10 or 15 years. And therefore, it makes more sense to invest in the new plant, even at $25, in the knowledge that, you know, that's not always going to be the case. An example of this was Synlait, who invested in an electrode boiler in their plant down in Canterbury. At 25 bucks a tonne that makes no sense at all. But it was a new boiler and they know that that's going to be in place for quite some time and so it makes very good economic sense within the life of that asset.
