Electricity prices are fucky all over the place and the general theme is there's more profit to be made in export rather than domestic consumption, which can result in ridiculous economies where energy is being exported at top dollar and imported at bottom dollar.

The math is supposed to work out but, like you said, basically the overabundance of "green" energy doesn't do anything for domestic energy markets. It is implicitly earmarked for export consumption rather than domestic consumption. Energy managers get to reap the benefits twice, with both domestic and export prices remaining high rather than domestic prices continuously falling as supply comes online.

The same song gets played out all over, throw carbon credits into the mix and things can get pretty silly pretty quickly.
