Energy Calculator

How much energy will that new air conditioner use?

What will it cost to run a dehumidifier in your basement for a month?

A first step toward reducing your bill is figuring out how much energy you now use - or how much you will use if you add new appliances. You can use the PSNH Energy Calculator to accurately determine the monthly cost of operating an individual appliance - or everything in your home.

Our Energy Calculator is a secure system and requires a PSNH account number in order to be used.
