Supplier Code of Conduct

The Supplier Code of Conduct sets out Hydro-Québec’s expectations with respect to suppliers with whom it has a business relationship (any connection or exchange, verbal or written, with or without a contract) as well as its subcontractors. The code is in addition to the applicable laws, regulations, standards and rules in force in Québec as well as any existing contractual commitments between Hydro-Québec and its suppliers.

Ethics is the cornerstone of this code. This means that in their business relations with Hydro-Québec, suppliers must act with integrity, honesty and professionalism and adhere to the highest ethical standards while respecting human rights and the environment, in order to maintain and strengthen public confidence in the integrity of Hydro-Québec and its activities.

In 1997 and subsequent years, Hydro-Québec restructured itself into divisions, which enabled it to obtain a power marketer’s licence and sell electricity at market prices on U.S. wholesale markets. This structural unbundling is known as deintegration.

The divisions were replaced by groups in 2021. The concept of deintegration continues to be strictly applied for all activities for which it is necessary to prevent any form of cross-subsidization or to ensure a level playing field for all market players. To this end, rules of conduct and ethics were enacted and integrated into internal directives, which are briefly described below:

Transmission Provider Code of Conduct: Governs relations between the Transmission Provider and its affiliates, and is intended to prevent any form of preferential treatment or cross-subsidization.

Reliability Coordinator Code of Conduct: Ensures that the reliability of the transmission system remains the Reliability Coordinator’s top priority and prevents any form of preferential treatment in favor of other structural units of the Transmission Provider, its affiliates or other system users.

Code of Ethics on Conducting Calls for Tenders: Ensures that the Distributor’s tendering process is conducted fairly for all electricity suppliers.

Code de conduite du Distributeur [Distributor Code of Conduct]: Regulates transactions between the Distributor and the Generator for non-tendered electricity supply in order to ensure that the Generator does not benefit from any unfair advantage. It also governs dealings between the Distributor and its affiliates, with the aim of preventing affiliates’ business operations from being subsidized, in whole or in part, by electricity service customers.

The application of each of these codes is the subject of an annual accountability report to the Régie de l’énergie.
