The average electricity cost in Connecticut is about 21 cents/kWh. That includes delivery (the service your utility provides, plus hidden taxes and fees) and supply (the cost of the electricity itself, which is paid to third parties).

The actual rate varies depending on your electric utility (UI in most of the New Haven area), and which generation supplier you choose. Check EnergizeCT.com for competing supply rates.

Typical Connecticut residential usage is 700 kWh/month, so if you do the math that comes to $147 a month, plus a monthly fixed fee of $12.84 for UI customers, bringing it to about $160 a month. Obviously, if you use a lot of electricity you're going to pay more. So if you plan to have a grow room in your basement, or if you're a big gamer, expect a higher bill.
