Load balancing

Load balancing is the management of natural gas storage and variations between summer and winter consumption. The price of this component is adjusted annually, in early October. Gaz Métro bills load balancing at the same price we pay our suppliers for load-balancing tools.

This is the service that sends the natural gas through pipelines from the production sites to Quebec , the territory served by Gaz Métro. The transportation prices are modified when Gaz Métro transportation suppliers modify their own prices. We bill this service at the same price as what we pay the transportation companies.

Inventory-related adjustments

The natural gas supply price is coupled with an adjustment that reflects variation in the value of inventories caused by a change in the natural gas supply as well as the costs of maintaining these inventories.

Cap-and-Trade System

The emission allowance cost for the natural gas combustion, which varies each month. Cap-and-Trade System is an economic tool of the Québec government aimed at reducing greenhouse gas emissions. Fuels consumed in Québec are covered by the Cap-and-Trade System through energy distributors like Gaz Métro. The sums collected will be invested by the government in, among other things, measures aimed at combating climate change.


The price of the natural gas delivery service throughout the Gaz Métro distribution network is adjusted annually. The rate is assigned based on your consumption and applicable to the general, stable or interruptible services. Gaz Métro derives its earnings solely from this component of your bill.

The price of the general distribution service is the sum of two components:

  1. Basic fees: the fixed portion of the bill. They are determined by a rate that varies according to annual consumption and are billed by the meter based on the number of days in the billing period.
  2. Unit price by volume withdrawn: a variable component of the bill. It is applied to the volume withdrawn during the billing period. The unit price decreases as the volume increases.
