A fairer way would be to treat electricity transmission as the natural monopoly that it is and to ensure that companies that do generation are not involved in transmission and vice versa. Transmission would be better handled by local government. If they want to favor homeowners' solar panels, so be it. If they want to favor the local power plant, again, so be it. If you let generators run the grid then they will do everything in their power to kill any forms of competing power and they will succeed thanks to their monopoly power. There is no intrinsic reason why rooftop solar shouldn't be given subsidies (direct or indirect), also. It is greener than almost all alternatives, after all.
