Because that's what utility monopolies do. They suck up your cash, then figure out how to suck up your neighbor's cash.
While I can appreciate your cynicism, your statement is incorrect when applied to utilities, which are highly regulated monopolies. Utilities want nothing to do with solar power because they recognize the economic inefficiencies inherent in such power generation. But they are being forced by governmental regulatory agencies (public utility commissions) to front for the green-solar lobby and are being forced to promote and pay for (through government mandated fee increases) these goofy power schemes.
These "fees" are nothing more than increased taxes coming through the backdoor of, and being collected by, the utilities, and have nothing to do with whether the utilities are monopolies.
