An essential transition for Îles-de-la-Madeleine

Adopting a new model based on energy efficiency and renewable sources of power is a clear choice for the Îles-de-la-Madeleine

The energy transition involves the gradual replacement of energy produced from fossil fuels with various forms of renewable energy. Hydropower, a source of clean, reliable energy, and other renewable generation options such as solar and wind power are part of the proposed solution for supplying the islands with sustainable energy.

The energy transition also goes hand in hand with developing new habits, such as putting an end to wasting energy, and the emergence of a culture of energy efficiency.

Current situation

  • Hydro-Québec’s largest off-grid system, serving 6,600 customers
  • Dependent on fossil energy
  • Thermal power generation :
    • 40 million litres of oil burned every year
    • 40% of Hydro-Québec’s direct greenhouse gas emissions in 2017

Future situation

  • 94% reduction in greenhouse gas emissions from power generation in Îles-de-la-Madeleine
  • 20% to 25% reduction in power generation costs (over 40 years)
  • Increase in grid capacity, giving a boost to economic development and transportation electrification initiatives

Provide clean, renewable energy

Starting in 2025, the islands will be supplied with Hydro-Québec’s clean and renewable energy via underground and subsea cables from Percé substation, located in Val-d’Espoir, Gaspésie.

Duration: 2 minutes 41 seconds

Microgrid

Working in partnership with the community, Hydro-Québec will set up a microgrid that uses other renewable energy sources, energy storage batteries and various solutions for managing power consumption in buildings.

Thermal power plant

The thermal power plant will be maintained as a backup facility that can be used during maintenance operations or in the event of a power outage.

Stringent requirements for project execution

In developing each new project, we work to strike a balance between the following four aspects: reliability, community needs, environmental factors and economic considerations.

  • Maintain employment levels and create new opportunities
  • Adapt energy efficiency programs (such as the Efficient Energy Use Program)
  • Hydropower supplied by two strong cables with an 80-MW capacity
  • Durable solution that will meet the needs of island residents for the next 40 years or more
  • Seabed uses and particularities taken into account in designing and installing subsea cables
  • Preservation of the thermal power plant as a microgrid backup facility for greater flexibility (intermittent production, maintenance, etc.)
  • Respect our employment-related commitments
  • Economic spinoffs during construction and operations
  • Use of green energy as a lever for economic development (capacity exceeds current needs)
  • Lower Hydro-Québec costs – conducive to maintaining affordable rates

  • Reduction in greenhouse gas emissions by 94%
  • Factor conducive to converting all customers to electric heating
  • Limited environmental impact
  • Factor conducive to the electrification of ground and maritime transportation

Hydro-Québec’s commitment to residents

  • Maintain employment levels
  • Hold consultations and discussions during project development
  • Adapt energy efficiency programs as required
