Re:<What was the average selling price of electricity produced from 100% green/renewable resources again in compliance markets? I didn't see that figure in your calculations.>
Since electrical power from all utilities goes to the grid, the market price for power is largely dictated by the price of coal power production. Renewable sources can get a premium to that by selling green tags. In Minnesota, I can buy a block through my power company at $0.02/kWh so that would make my effective retail price $0.093/kWh instead of $0.073/kWh. That link I provided earlier shows average green tags are worth between $0.015 and $0.02/kWh which is consistent with what is offered in Minnesota.
Unless USSE wants to build their own power distribution network (which I don't doubt since that will allow them to stall even longer), they're going to have to sell any power at the going rate and hope to make up the rest in green tags.
