I'm sure there is a simple answer and I'm an idiot, but given it's in a place that gets lots of sun, can they not just install solar panels with batteries at consumer/grid level?
Or is the problem not with the generation of the power and with transmitting it to properties? I don't know cost of solar installation but I'm sure the amount it's costing them when it all fails they could at least incentives individuals to install solar or something.
If these were stories I was picking up to implement I would be asking the BA to elaborate some more π
