Numerous projects are carried out every year, be it to maintain the system, ensure its long-term operability or to increase its capacity.
Teams plan these projects based on medium- and long-term needs, while taking into account Québec’s specific geography—a vast territory to supply—and climate.
Each project’s design is unique. Specialized teams work for many months to identify the scenario with the smallest environmental and social impact.
Laurentides and Lanaudière regional power transmission system planning
To meet the current and future electricity needs of Quebecers, Hydro-Québec thinks long-term when planning its transmission system. To support the economic development of each region and secure the electricity supply of its customers, Hydro-Québec makes sure to upgrade its transmission system appropriately and at the right time. The solutions proposed must be able to meet electricity demand for the next 20 years.
On the territory of the five MRCs listed above, several substations and transmission lines have reached, or will soon reach, their maximum capacity.

Major growth in the Laurentides and Lanaudière
The rate of growth in the Laurentides and Lanaudière is much greater than in the rest of Québec. New neighborhoods are being built, businesses and industries are moving in, and tourism is becoming increasingly important for the region. In addition, people are turning their cottages into main residences for year-round living, equipping them with appliances they may not have had before.
All these factors contribute to the significant increase in the region's electricity needs.
