The reality is you’ve confirmed my earlier assessment and that you’ve never done serious engineering economy-type financial analysis past maybe a house mortgage.
The reality is they don’t pay more for the electricity then (ask any of your friend who have solar) so charging more is simply taking advantage. There’s no reason why they couldn’t put the cost of the extra capacity into ALL the pricing. In fact you know full well it is. Peak pricing is PROFIT time. You know it. I know it. They know it. Stop putzing about.
