> The best thing to do is for the city to own both fiber and electricity, and let providers compete for both.

Something similar is the case in the European Union, as the electricity network is usually a different company than the electricity providers. The network is often owned by some municipal company and charges customers only for the transport of energy over the network. For the energy itself customers can choose from dozens of different providers, some of them generate their own electricity, others just buy and resell electricity on the market.
