Government electricity is kind of funny. With a government-owned power monopoly, people will vote to keep their rates low, and if the power agency runs out of money, they'll get mad.
And when the power agency decides to raise rates, they'll get mad.
Monopolies just don't work well. Lubbock and other cities should open power generation up to free-market competition, and customers should be able to choose who they want to buy their power from.
