If a residence is completely disconnected from the grid, thereby never being able to use utility generated electricity, then they should pay nothing.
On the other hand, if a residence is connected to the grid and drawing power from the grid at any time or simply able to do so, then that residence should be paying for the cost of any electricity used plus a charge for the infrastructure. It would seem that utilities need to break out their charges to include a component for infrastructure support. Each home in a community would pay the same fixed infrastructure fee. If that were the case, then the residence drawing power from the grid during certain hours would be paying a monthly infrastructure support charge just like his neighbors plus the cost of generating any electricity used during that month. It does not seem fair that a residence using solar generated power should be able to rely on the electric utility for backup without paying a fee for that backup service. A home having no connection to the grid does not have the ability to tap utility supplied electricity. Hence no fee for them.
If a house with solar power panels uses the regular power grid at any time, they should just have a meter and be billed on a per-usage basis like everyone else.
Yes, Even if they are completely off the grid. As freekitty said in #11, “People with no children have to pay school taxes.”
People have always had to pay for services and utilities that the entire community uses even though any one individual might not use all of the services taxes and other fees support, we all pay for it. Schools, water, sewers, garbage, parks, etc...
