It costs them money to accept this electricity and to integrate it safely into their grid. For example, the incoming power from a rooftop PV installation has to be metered, and during a power failure, the power a PV installation would be dangerous, so it has be cut off. This means the power company meter and other equipment has to be more complicated. The power company gets very little electricity from a rooftop installation, and I doubt they make a significant profit from it. It is probably not worth it to them. This is not like asking Amazon to sell 10 copies a year of an e-book. Amazon can do that profitably because that business scales down and it is profitable even at a few dollars per year. It does not require Amazon to install something like a hardware meter at your house. - Jed
