I hope you are right!
This type of "photon tax" is a really bad precedent that will led to expansion if left unchecked.
I maintain a utility connection (to allow the grid to be my back up during poor solar weather) and am happy to pay the monthly charge (about $30USD/month) to use zero power - if I don't need any that month. This is fair to the utility and to me, they supply the cables and poles infrastructure and are paid for that. If I also draw energy from their system I pay on top of that minimum charge for each per kWh for the energy they supply. That is fair and reasonable. Heck, if they figure the minimum charge is not enough, then go ahead and recalculate what it needs to be to cover the actual costs, I am fine with that.
But in no world it is right or fair that they also get to charge for what energy I use via solar I produce and use (or don't use) with equipment and systems I bought and paid for, that I maintain and is none of their damn business. What cost did they have to provide the sunshine?
The idea they can charge for power we don't use, is akin to saying we have no right to cut our usage for ANY reason, ie if you use less power by turning off the A/C and just dealing with the heat, they should be allowed to charge you for power you didn't use. I mean, what is the difference (to them) whether you suffered with the heat, or ran an A/C unit totally on solar? If you choose to run a generator all day on natural gas, do they get to also charge you for the kWh you didn't purchase from the electric utility?
