About electricity prices in Connecticut
What the rate includes
The figures above are EIA average retail prices — the total revenue utilities collect divided by kWh sold. Your own rate depends on your utility, plan, and usage tier, so treat this as a Connecticut benchmark.
Lowering your bill
The fastest wins are usually heating, cooling, and water heating. Use the appliance calculator to find your biggest energy users, then shift heavy usage off-peak if your plan supports it.
