Understanding Your Electric Bill
To help you better understand your NSTAR Electric bill, below is an
example of a typical residential bill. Simply click on the red
buttons to learn what each section of the bill is all about.
Based on valuable customer feedback, NSTAR began sending
most residential customers a redesigned bill in March 2007. The bill is
easier to understand, provides customers with helpful bill
analysis information and includes a graph charting energy use
over a 13 month period.
This information is included on the front "Summary" page
of customers' bills. Page two - the "Detail" page of the bill -
provides all of the information customers received in the past.
This is your NSTAR Account Number. For every account you have with NSTAR, there will be a different account number.
All payments need to be made on or before this date to appear on your next bill.
This is the address NSTAR mails your bills to. In some cases your mailing address will be different from the address NSTAR provides service to.
This is the amount owed on your account. This amount will include all current, as well as any past due, charges.
When paying your NSTAR bill by U.S. mail, please fill in the amount you have paid in this box.
When paying your NSTAR bill by U.S. Mail, make sure to return the top portion of this billing statement with your payment.

In this portion of the bill, you will find how much electricity you used in kilowatt-hours (kWh). This is done by subtracting your previous month meter read from your current month meter read. For example, if your August meter read 20000, and in September it read 20400, then your Electricity Used would be 400 kWh.
This is the NSTAR rate you are currently billed on. More information about the different rates available can be found in the "Rates & Tariffs" section of www.nstar.com.
This is an up to 13-month history of your electricity use. It includes the meter number at the top of the chart, read date and the amount of kilowatt-hours you were billed for. An asterisk next to a read date indicates an estimated reading.
