How to read your NSP bill

This is a Nova Scotia guide. Rates, utilities and programs differ in other provinces; your advisor confirms what applies to your home and your province.

Your Nova Scotia Power bill holds the single most useful number for any solar or heat pump conversation: how much electricity your home actually uses. Here is how to find it, and what the rest of the bill is telling you.

The parts of a residential bill

Account summary

The first section shows your account number, the billing period, the amount due and the due date. Note the number of days in the billing period: usage figures only compare fairly when the periods are the same length.

Meter readings

The bill lists the previous and current meter readings and the difference between them, which is your consumption in kilowatt-hours (kWh). Check whether the reading is marked as actual or estimated. An estimated reading is a projection that the next actual reading corrects. For sizing a solar system, actual readings are what you want.

Charges

A residential bill has two main parts. The base charge is a fixed monthly amount for being connected to the grid, and you pay it regardless of how much you use. The energy charge is the price per kilowatt-hour multiplied by what you used. HST is added on top.

For reference, NS Power states that since May 1, 2026, the residential base charge is $20.08 per month and the energy charge is 19.128 cents per kWh, with a further change scheduled for January 1, 2027. Rates are set by the Nova Scotia Energy Board and change over time, so always read the current rate off your own bill.

Usage history

Most bills include a small chart comparing this period's usage with the same period last year, and an average daily use figure. This is the quickest way to see your seasonal pattern: high in winter if you heat with electricity, flatter if you heat with oil or wood.

The number that matters for solar

Installers size a system on your yearly consumption in kilowatt-hours, not on the dollar amount. To get it, add up the kWh from a full year of bills, or download your usage history from your online NS Power account. If you have less than a year of history in your current home, say so; the installer can estimate from the home's heating type and size.

The number that matters for a heat pump

Look at the difference between your winter and summer usage. A large gap, with winter usage several times higher, usually means electric heating is driving your costs, which is where a heat pump has the most effect. A small gap suggests your heat comes from another source, such as oil or wood, and the heat pump conversation shifts to fuel costs and comfort.

Other things you may see

• Equal or budget billing. Payments are averaged across the year. Your actual usage still appears on the bill; use the kWh figure, not the payment amount.
• Time-of-day rates. Some customers are on a rate that charges differently by time of day. If your bill shows usage by period, mention it to your installer.
• Self-generation lines. Once you have solar, your bill shows energy delivered to you, energy received from you and the banked kilowatt-hours applied.

Keep a year of bills, or your online usage export, handy before your assessment call. It turns a rough conversation into a precise one.
