Id love to know what the cost of electricity is, which should include amortization of assets, transmission, etc.

If I were Rio, I'd have calculated the cost benefit of moving the plant elsewhere, and started negotiations a long time ago, so i could actually move the plant if there were better offers elsewhere. Assuming it's currently profitable, which it probably is, otherwise other plans would already be in motion, I imagine the opportunity cost of shutting it down to open somewhere else outweighs keeping it running for another epoch.

I imagine it's fairly expensive to leave a plant like that unoperational, and I would guess it'd be near impossible to sell.

My guess is that rio will either keep it running for several years while another plant can be built elsewhere, or just put up with it, which is more likely.

Good time to buy power shares imo.
