Energy costs in St. Louis, MO
Energy prices are published by state, not by city, so the rates and bills below are Missouri figures and apply to St. Louis the same as anywhere else in the state. The solar production is different: that is modelled for St. Louis's own coordinates, and it varies a lot within a single state.
Solar at St. Louis's coordinates
8,327kWh a year from 6 kW
That is close to the Missouri average, so the state figure would not have misled you here. At 13.68¢ a kilowatt hour it pays back in about 10.3 years with full net metering.

Common questions
What is the electricity rate in St. Louis?
13.68¢ per kilowatt hour. That is the Missouri residential average from the EIA — rates are published per state, not per city, so it applies across St. Louis and the rest of Missouri alike.
What is the average electric bill in St. Louis?
About $145 a month for a typical Missouri household. Again this is a state figure: EIA reports revenue and customer counts by state, so a city-level bill would be an invention.
Is solar worth it in St. Louis?
A 6 kW system at St. Louis's coordinates is modelled at about 8,327 kilowatt hours a year, which pays for itself in roughly 10.3 years at Missouri electricity prices with full net metering. This one is genuinely local — production is modelled for this point, not the state.
