An innovative project to serve an engaged community.

Lac-Mégantic is a city that is looking to the future and focusing on innovation. The region’s commitment to sustainable development and the community’s efforts to rebuild the downtown area make Lac-Mégantic the ideal place to implement the most advanced energy technologies.

Lac-Mégantic’s microgrid will be adapted to the municipality’s reality and will evolve as the downtown area is redeveloped.

A project that reflects the energy transition

The energy landscape is undergoing a period of intense change. Renewable energy sources and responsible electricity use are the keys to the energy transition.

There are different ways of generating clean and renewable energy. Hydropower plays a crucial role. Other energy sources, such as solar, are becoming increasingly popular despite the intermittent nature of the energy source and the associated storage and integration challenges.

The wise use of energy, thanks to new technologies and evolving habits, is part of an energy efficiency culture.

The most advanced energy technologies will be deployed in the new downtown area of Lac-Mégantic. These technologies will also be used in the off-grid systems (those not connected to the main Hydro‑Québec grid) that currently rely on fossil fuels. The objective: decrease greenhouse gases while ensuring a sustainable energy future for generations to come.

The Lac-Mégantic microgrid

  • It is a community-centered initiative.
  • It meets the needs of local users.
  • It comprises various interconnected energy generation, storage, management and control components.
  • It is connected to Hydro‑Québec’s main grid and can function independently.
