Energy costs in Sioux Falls, SD
Energy prices are published by state, not by city, so the rates and bills below are South Dakota figures and apply to Sioux Falls the same as anywhere else in the state. The solar production is different: that is modelled for Sioux Falls's own coordinates, and it varies a lot within a single state.
Solar at Sioux Falls's coordinates
8,454kWh a year from 6 kW
That is close to the South Dakota average, so the state figure would not have misled you here. At 15.73¢ a kilowatt hour it pays back in about 8.9 years with full net metering.

Common questions
What is the electricity rate in Sioux Falls?
15.73¢ per kilowatt hour. That is the South Dakota residential average from the EIA — rates are published per state, not per city, so it applies across Sioux Falls and the rest of South Dakota alike.
What is the average electric bill in Sioux Falls?
About $138 a month for a typical South Dakota 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 Sioux Falls?
A 6 kW system at Sioux Falls's coordinates is modelled at about 8,454 kilowatt hours a year, which pays for itself in roughly 8.9 years at South Dakota electricity prices with full net metering. This one is genuinely local — production is modelled for this point, not the state.
