It is far more complicated than just “maintaining” the cables as most lay people think when they hear grid costs.
The problem is that the grid has to match power demand with the roughly the same amount of power generation during all the time. So, if a cloud passes over your system and reduces your output by 25%, those 25% need to come from somewhere, usually from rotational inertia from giant steam or hydro turbogenerators in the nearest second, and either by regulating steam production or water flow in the long run or if necessary by either taking offline generator or adding more easily dispatchable power sources. And all the while making sure the frequency keeps very close to 60hz all the time. It is not just about sending a man in a pole to change some insulators from time to time. |

how is it exactly fair that in case when there are two households having same minimal use (essentially grid connection price) with one of them having 10k of solar, the household without solar will pay $10 per month and the other one will pay $90 per month ? (as i said, they consume same amount of energy from grid)
