I can understand the justification for electric utilities to charge solar customers for line use and infrastructure, however, this fair reason is not the reason the Koch bros and friends are pushing for these kind of charges.
You said the Oklahoma law was directly related to the Koch Bro's ...... while they may be anti-solar or what ever, the Oklahoma law has nothing to do with them, and is directly aimed at compensating the utility companies for line use by solar and wind generating customers looking to sell their surplus electricity back onto the grid.
I don't like the new law but I understand the reasoning behind it, your post is only speculation and aimed at smearing the Kochs
