May I add to that, because I think that's the point that is key from the design and construction perspective?
The approach that PSPC has taken in terms of its development of option analysis doesn't only take a look at the technical requirements of a project. It's actually alongside and then primarily takes a look at the GHG reductions associated with different options to meet those technical requirements, and that is a significant change in the way that we, PSPC, for our own projects, have undertaken the analysis and design requirements stage.
