The energy of an entire community

I’m sure that when you think of Hydro‑Québec, you think of hydropower. But the government corporation also operates other types of generating stations to supply isolated communities.

This is the case in Les Îles‑de‑la‑Madeleine, a community that has always relied on fuel oil to meet its energy needs. I’m like a gigantic generator. With my six 11,000 kilowatt generating sets, I supply electric power to nearly 13,000 people.

I’m also modern and environmentally conscious. For example, I use recycled water, which reduces my fresh water consumption by 70%. My system for recovering the heat released by my motors also saves a lot of energy. Pretty good, right?

My guides will tell you even more if you come visit me. I look forward to welcoming you to my beautiful part of the world!

Did you know?

Safety first!

I have my own squad of 12 volunteer firefighters, who are always ready to act quickly while the municipal fire department arrives. They can also help out with local fires.

Like ship engines

I have six 11,000‑kilowatt diesel engines. They are like those used on many ships. Technicians who have studied at the Institut maritime du Québec oversee their maintenance.

A personalized service

The 7.2‑km2 Île d’Entrée is the only inhabited island that isn’t connected to the archipelago by land. The few dozen people who live there can count on their own generating station that has a capacity of 1,150 kilowatts.

Cutting-edge expertise

There has not been a blackout in Les Îles‑de‑la‑Madeleine since 2009. That’s because the teams on site have developed world-class expertise in operating a diesel‑fired generating station.

My history

I was built in Cap‑aux‑Meules in the early 1990s, and I’m quite proud to serve the archipelago’s 13,000 inhabitants, with the help of some 80 employees. In recent years, we’ve gotten a good bit of help from the wind energy generated by the 6.4‑MW Dune‑du‑Nord wind farm.

1944: First phase of electricity nationalization in Québec

1949: Birth of the electricity cooperative

The electrification of Les Îles‑de‑la‑Madeleine is relatively recent. At the very end of the 1940s, the island’s electricity cooperative was created. It contributed to the archipelago’s electrification. At the time, shares cost $5 each and were tirelessly sold by those who were committed to the initiative. Isaac Boudreau (1913‑1978) was one such person. He was a resident of Les Îles‑de‑la‑Madeleine who became a Hydro-Québec employee following the second phase of electricity nationalization in 1963. He even worked at Hydro‑Québec’s Institut de recherche en électricité (IREQ) from 1973 onwards.

1953: Inauguration of the electricity cooperative’s generating station

The first thermal generating station in Les Îles‑de‑la‑Madeleine was the one developed by the cooperative thanks to a $420,000 loan from the Rural Electrification Agency. When it was launched, it had two generating units and served just over 400 customers in Cap‑aux‑Meules and Havre‑aux‑Maisons. In 1954, Havre‑Aubert was connected, and then the rest of the archipelago, except for Île d’Entrée. From 1963 to 1982, the generating station was expanded several times in order to meet the growing demand.

1960: Beginning of the Quiet Revolution in Québec

1962: Election of Jean Lesage’s Liberal Party (Maîtres chez nous!)

1963: Second phase of electricity nationalization in Québec

The second phase of electricity nationalization in 1963 was very beneficial for the residents of Les Îles‑de‑la‑Madeleine, who saw their electricity costs cut in half.

1976: First election of René Lévesque’s Parti Québécois

1991: Commissioning

At the end of the 1980s, the generating station was nearing the end of its service life. The population was increasing and the mining and fishing industries were growing. Connecting the islands to the main system was considered, but it was ultimately a brand new 66‑MW generating station (me!) that was built and inaugurated in 1991, the largest diesel-powered thermal generating station in Québec. It is part of the company’s off‑grid system.

It’s well worth the trip!

Don’t take our word for it: this is what the people who visited the thermal generating station with our guides had to say.

I really appreciated the knowledgeable guide and her explanations.

Good explanation of the site and the technology.

Thank you very much! I think it’s great that we can tour our generating station.
