What factors affect my bill?

There are many factors that can affect the charges on your monthly bill. Here are some examples of factors ​that might affect the charges on your bill:

Rate Changes 

Rate changes

Albertans on variable rate plans or those on regulated energy rates can expect more volatility in energy prices across Alberta than they have experienced in the past.


Weather or seasons

Seasonal high or low temperatures affect rates as we use more energy to stay comfortable, which can increase demand in the market. Have a look at these Energy Saving Tips for easy and low-cost ways to reduce energy consumption.   


Changes around your home

Everyone contributes to how much energy is used. Continuing to work from home or having family and friends stay for a visit can lead to changes in your energy consumption.


Days between bills

ENMAX bills are generated when we receive meter readings, and the time you’re charged for could range from 27 to 35 days. You’ll find the number of days your energy is billed for on page 3 of your invoice.

meter estimates 

Meter estimates

When electricity or natural gas meters can't be read in person, your usage will be estimated based on the last confirmed reading. In most cases meter estimates only happen for a single billing period - but there are situations where consecutive billing periods will need to be estimated.

New appliances/electronics

New appliances or electronics can increase or decrease how much energy you use.


Taxes and Government policy

Government policy such as taxes or rebates can affect how much you pay for electricity.

The Federal Carbon Tax (sometimes referred to as the Federal Fuel Charge) appears as a separate line item on natural gas bills and consumers must pay it just like any other federal charge, such as the GST.

Some consumers may be exempt from paying the Federal Fuel Charge. For more information, visit the Canada Revenue Agency (CRA) website.

Eligible individuals and families may receive a Canada Carbon Rebate (formally known as the Climate Action Incentive Payment) from the Federal Government. To learn more, head here.

Any Federal or Provincial rebates and exemptions are administered by the appropriate jurisdiction and not through ENMAX.

Customers are free to purchase natural gas services or electricity services from a retailer of their choice. For a list of retailers, visit ucahelps.alberta.ca or call 310-4822 (toll free in Alberta).
