maybe that would have been ok. but they would have had to build the Stage 1 solar and PHES at the same time, and it have been a lot harder to get finance for that.

Anyway that's not how they did it, so they (and others) are precluded from optimal operation by rules that were not designed for the grid of the future. Having said that, I don't see why Genex can't make a submission to the AEMC requesting a rule change??
