Solar generating stations at La Citière and IREQ

Over summer 2020, Hydro-Québec will build its first two photovoltaic solar generating stations. The stations will be connected to the grid and will have a total installed capacity of 9.5 MW.

The locations chosen for the construction of the planned generating stations are on land owned by Hydro-Québec in Varennes (Hydro-Québec’s research institute) and La Prairie (former site of the La Citière thermal generating station).

Objectives

In addition to generating electricity from solar radiation, a source of renewable energy, this project will aim to achieve a number of objectives, including:

  • Developing Hydro-Québec’s expertise in photovoltaic generation as a complement to other generation sources.
  • Evaluating centralized photovoltaic power generation in Québec and expanding Hydro-Québec’s knowledge of the effects of photovoltaic generation on the power grid and generating fleet management.
  • Determining which photovoltaic technologies are best suited to conditions in Québec and to the Hydro-Québec grid.
  • Helping establish Hydro-Québec’s future development strategies in the context of the energy transition, in accordance with Hydro-Québec’s 2020–2024 Strategic Plan.
  • Following up on Québec’s 2030 Energy Policy and accompanying action plan, which set out to grow Hydro-Québec’s expertise in centralized solar power generation using a photovoltaic solar generating station project in Québec.

How photovoltaic solar generating stations work

Photovoltaic solar generating stations convert energy from solar radiation into electrical energy. Their main components are shown in the diagram to the left.

Hydro-Québec will begin building solar generating stations in La Prairie and Varennes in 2020

Hydro-Québec will begin building solar generating stations in La Prairie and Varennes in spring 2020. Commissioning is scheduled for fall 2020. This project will allow us to conduct the necessary tests to determine whether solar energy is well adapted to the Québec climate, to our generating fleet and to our transmission system.

The first photovoltaic panels of the new solar generating station in La Prairie are now installed!

There will be close to 26,000 bifacial panels on the site of the future generating station. Bifacial technology makes it possible to capture direct solar radiation on the panels’ top surface and indirect reflected radiation from the ground on the rear surface.

The construction of the two generating stations has entered the homestretch!

The installation of the panels has been completed and the trial phase is under way.

This fall, the French-language Québec magazine for youth about science, technology, society and the environment, Curium, published an article on our photovoltaic solar plants [PDF 230 kB].
