Why is my energy bill higher in the winter?

Why is my energy bill higher in the winter?

Updated on February 12, 2026

As temperatures plummet, gas and electricity bills rise. If you’ve noticed an increase in your energy costs during winter, here are some reasons why.

1. Increased energy usage

As Alberta’s days grow shorter and colder, we naturally retreat indoors. This shift, combined with the extreme cold snaps we’re known for, forces furnaces, space heaters and lights to work overtime. If you’ve felt the impact on your bill as the weather drops well below zero degrees, you’re not alone.

2. Delivery charges

When energy demand is high, the system becomes more taxed, driving up energy costs and delivery charges. The delivery charges are approved by the AUC and billed on behalf of your distributor—and are consistent regardless of your retailer.

These costs:

  • Cover the safe transportation and delivery of energy to your home.
  • Maintain and operate the infrastructure bringing energy to your community.
  • May change based on the number of billing days, or the amount of energy used.

3. Fluctuating energy rates

Variable electricity rates, along with variable and regulated natural gas rates, change from month-to-month depending on weather and market conditions. If you’re looking to avoid market ups and downs, you could lock in a fixed rate plan. Another option for a predictable monthly bill is Average Billing. This tool calculates a rolling average of your usage, spreading your energy costs throughout the year.

4. Billing period length

Though unrelated to winter weather, the length of your billing cycle—which can vary from 27 to 35 days—also affects your payment. A longer cycle captures more days of energy use and results in a higher bill, while a shorter cycle will appear lower.

While seasonal weather and delivery charges are beyond your control, you can still lower your bill by reducing consumption and improving home efficiency. Explore our tips to stay warm, save money and keep your home running efficiently this winter.

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).
