We are required to charge the same electricity rates throughout Québec. Our rates are based on the consumption profile of our different customer categories.

Thanks to the investments made by previous generations and the abundance of water resources, Québec has a heritage pool of electricity available at a very competitive rate compared with the rest of North America.

Every year, we file a rate case for approval with the Régie de l’énergie. Our application to increase rates is analyzed through a rigorous process that includes public hearings at the end of the year, during which representatives of all stakeholders can express their views.

To support our application, we submit details on the expenses we expect to incur to provide electricity to all Québec customers in the next year, and the revenue we expect to generate.

  • The rate adjustments in the last three years, 0.7% on April 1 in 2016 and 2017 and 0.3% on April 1, 2018, reflect our commitment to keep rate increases lower than or equal to inflation. Without the efficiency gains of approximately $590 million achieved over the past 10 years, rates would be about 5% higher in 2018–2019.
  • Payment arrangements were signed with residential customers to facilitate settlement of 366,839 cases representing $731 million gross in arrears; the arrangements cover forecast consumption over the duration of the agreements.
  • 106,438 payment arrangements covering $483 million gross were reached with low-income customers; 46,974 of the agreements, amounting to $56 million, provide assistance with payment of arrears and, if necessary, partial payment for current electricity use.
  • Pilot projects tested agreements tailored to the payment capacity of low-income customers. These initiatives included a more generous agreement and gradual cancellation of the debt.
