I don&#x27;t know why your first point is relevant, the marginal cost of billing is incredibly minute. The second point is interesting but calling it poaching is tendentious. No one is saying power stations, transmission lines, distribution networks, voltage support, frequency regulation, or any of the other myriad features of modern electricity grids are free. The point is how do you distribute the costs of those goods fairly (i.e. in proportion to use). Utilities are saying netmetering is unfair because it results in stranded costs that must be born by non-solar customers and I am saying that they are overestimating their stranded costs to the extent that they don&#x27;t count the increase in the efficiency of their ability to serve load (because solar gen is basically already made and delivered electricity they bill for but don&#x27;t have to buy). It is a really really hard question to know by how much they are overestimating stranded costs.<p>IMO this is about aggregate demand and the stranded cost thing is a red-herring.
