Energy costs in Washington, DC
Energy prices are published by state, not by city, so the rates and bills below are District of Columbia figures and apply to Washington the same as anywhere else in the state. The solar production is different: that is modelled for Washington's own coordinates, and it varies a lot within a single state.
Solar at Washington's coordinates
8,349kWh a year from 6 kW
That is close to the District of Columbia average, so the state figure would not have misled you here. At 25.40¢ a kilowatt hour it pays back in about 5.7 years with full net metering.

Common questions
What is the electricity rate in Washington?
25.40¢ per kilowatt hour. That is the District of Columbia residential average from the EIA — rates are published per state, not per city, so it applies across Washington and the rest of District of Columbia alike.
What is the average electric bill in Washington?
About $152 a month for a typical District of Columbia 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 Washington?
A 6 kW system at Washington's coordinates is modelled at about 8,349 kilowatt hours a year, which pays for itself in roughly 5.7 years at District of Columbia electricity prices with full net metering. This one is genuinely local — production is modelled for this point, not the state.
