Lifestyle & Electricity

It is important to be aware of the impact electricity has on our lifestyle and finances.  Below are links to charts to help estimate monthly residential appliance electricity usage.Typical usage cost, as well as the Transmission & Distribution (T&D), costs are included, and are billed by Emera Maine. They are combined in these charts into one column "Average Monthly Cost for Delivery (T&D)".

Two columns in the charts are blank. Instructions are given below to complete those columns. The "Electricity Supply" charge is determined by the company from which you purchase electricity. If you have not selected a company, you are most likely on Standard Offer Electricity Supply and that charge is established by the MPUC.

Note: T&D charges must be added to Electricity Supply charges to calculate total cost.

Using the Charts

1. Mark each item in the list that you use in your home.
2. Add together the "Estimated kWh/Month" for all items marked.
3. Multiply the total "Estimated kWh/Month" by the total cost per kWh (see page 1). This gives you an estimated monthly cost for the items marked.
4. Remember, the list may not include everything in your home. Also, your home may use items more or less than average. Therefore, remember this is simply an average estimate, depending on the households’ usage.

Another Use of the Charts

To calculate the cost per item, and to fill in the blank column "Average Monthly Cost for Electric Supply" do this calculation:

1. Multiply "Estimated kWh/Month" (from the charts on pages 4 through 9) by "Electric Supply Charge Per kWh" that you calculated and entered on page 1. This equals "Average Monthly Cost for Electric Supply" for the item you selected.
2. For each item, add the amount in this column, "Average Monthly Cost for Electricity Supply" to the amount in the "T&D" column and fill in the last column. This will give you the estimated cost per month for that item "Total Cost (T&D plus Supply)."

Lifestyle & Electricity Usage Charts

These charts (PDF) list typical residential usage. Costs for your home may differ due to family size or lifestyle, as well as wattage, age, efficiency and extent of use of electrical items.

These charts (PDF) help you estimate your monthly appliance usage and encourage you to use high-energy items more wisely. They can also help you evaluate purchases of new electrical items.
