How Connecticut compares
At 29.1¢/kWh, Connecticut has the 4th-highest residential electricity price of the 50 states and DC — 58% above the 18.4¢ US average. That puts it firmly in the expensive tier, where every kilowatt-hour you can avoid buying — or generate yourself — is worth more. For context, the cheapest power in this data is Idaho at 12.3¢, and the most expensive is Hawaii at 41.1¢.
Over the period in the chart above, Connecticut's average rate has risen about 3% — in line with a long national trend of electricity prices climbing faster than they used to, driven by grid upgrades, fuel costs and surging demand.
What your rate means for the big decisions
Your electricity price is the single number that drives whether solar, an EV, or electric heating saves you money. At Connecticut's 29.1¢/kWh:
- Rooftop solar pays back in about 13.1 years for a typical home here — high rates are exactly what make solar pay off quickly. See the full breakdown on the Connecticut solar payback page, including local utilities, net metering and incentives.
- Charging an EV at home costs about 9.7¢ per mile here, versus roughly 12.2¢/mile for a typical petrol car — see the Connecticut EV charging breakdown.
- Cooling and heating swing with this rate too — check what running your AC costs in Connecticut, or whether a heat pump beats gas at 29.1¢/kWh.
