Energy costs in New Haven, CT
Energy prices are published by state, not by city, so the rates and bills below are Connecticut figures and apply to New Haven the same as anywhere else in the state. The solar production is different: that is modelled for New Haven's own coordinates, and it varies a lot within a single state.
Solar at New Haven's coordinates
7,720kWh a year from 6 kW

Common questions
What is the electricity rate in New Haven?
27.37¢ per kilowatt hour. That is the Connecticut residential average from the EIA — rates are published per state, not per city, so it applies across New Haven and the rest of Connecticut alike.
What is the average electric bill in New Haven?
About $203 a month for a typical Connecticut 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 New Haven?
A 6 kW system at New Haven's coordinates is modelled at about 7,720 kilowatt hours a year, which pays for itself in roughly 5.8 years at Connecticut electricity prices with full net metering. This one is genuinely local — production is modelled for this point, not the state.
