Peak Demand Management

51³Ô¹ÏÍøhas enrolled in Hydro Québec’s Peak Demand Management (PDM) program. During extremely cold weather events, Hydro Québec will call for its clients to reduce power demand, thus reducing the strain on the province’s power infrastructure.

When?

From December 1, 2025 to March 31, 2026.

10 to 20 periods between 6 AM – 9 AM and/or 4 PM – 8 PM

Mondays through Fridays on extremely cold days (excludes December 24, 25, 26, and 31, January 1 and 2, as well as Good Friday and Easter Monday when they fall within the winter period).

Safeguards

  • If temperature in any space drops below/above the above parameters, heating/air conditioning will automatically kick in to get back to acceptable conditions.
  • All systems to return to normal mode outside of PDM periods.
  • At least one elevator to be kept running to maintain accessibility to the building.
  • No change in animal labs, sequencer rooms, and other critical areas defined with building directors.

With the participation of:

  • Hydro Québec
  • 51³Ô¹ÏÍøUtilities & Energy Management
  • 51³Ô¹ÏÍøBuilding Operations
  • Building Directors

Background information

Québec’s power demand profile is atypical in that it peaks in the winter (as opposed to the summer for most North American jurisdictions) due to the high penetration of electrical heating on the market. During these events, Hydro Québec must purchase power at a hefty cost from neighbouring provinces and states. Further to being extremely expensive, electricity generated in other jurisdictions is much less clean that Québec’s energy mix. Building new electricity generation infrastructure (hydro dams or wind farms) isn’t in the interest of the province as such infrastructure would be grossly underutilized and would not be profitable on the long run. Demand-side management programs that call for end-users to reduce their demand are a much more effective and sustainable way to reduce the financial and environmental impacts of having to purchase power from other jurisdictions.

Performance of previous years

51³Ô¹ÏÍøhas beenÌýparticipating in the PDM program since winter 2015/2016.ÌýDuring the previous three years, we were able to reduce our power demand from the grid around 3,000 kW per event, which is like shutting off around 2,000 electric baseboard heaters or stopping the charging of more than 400 electric vehicles.

Winter period Power reduction Equivalent reduction in number of electric baseboard heaters turned off Equivalent reduction in number of electric vehicles unplugged from charger
2019-2020 3,384 kW 2,256 470
2020-2021 2,891 kW 1,927 402
2021-2022 2,684 kW 1,789 373
2022-2023 3,048 kW 2,032 423
2023-2024 3,231 kW 2,154 449
2024-2025 1,984 kW 1,322 276

*Projects at McIntyre Medical and SAD in 2024-2025 prevented use of generators for peak demand management.
