Excellent business opportunities

By choosing our energy, which is more than 99% renewable, you are contributing to the energy transition and gaining an edge on the competition. You are decreasing your greenhouse gas (GHG) emissions by using one of the energy sources with the lowest carbon footprint in the world. This makes you part of the solution. You’ll significantly improve your carbon footprint: that’s one step closer to net zero emissions!

A greenhouse gas (GHG) is a gas present in the atmosphere, of natural or man-made origin, which absorbs and reflects infrared rays coming from the earth’s surface. The increased concentration of these gases in the atmosphere contribute to climate change

Assessment of consumption attributable to heating

The percentages below reflect the typical consumption profile by use and the percentage devoted to space and fresh air heating (for baseboards, coils or an electric furnace):

  • Supply: 20%
  • Education: 60%
  • Other: 45%

Where heating is provided by a geothermal or aerothermal system, the above percentages are reassessed based on the seasonal efficiencies shown below. These efficiencies take into account the fact that the heating system is sized to meet 50% of the maximum heating demand, with excess heating requirements met by baseboards, coils or an electric bolier. The outdoor temperature data from the SIMEB weather file for the city of Québec is used for the calculations:

  • Aerothermal system: 180%
  • Geothermal system: 320%

The energy transition

What is the energy transition?

The energy transition can be defined as all the changes in electricity generation methods and transmission and distribution systems throughout the world as well as current energy consumption habits.

In other words, the energy transition represents all the changes undertaken to reduce the environmental impact of generating, transporting, distributing and consuming energy, in particular by replacing fossil fuels with clean, renewable energy sources.

What are the issues facing the energy transition?

More than ever, the energy transition is a social, environmental and economic priority. It involves a significant decarbonization of human activities, which means that fossil fuels must progressively be replaced by energy solutions combining energy efficiency and renewable energy within a growing demographic context and the corresponding increase in demand.

This major challenge is nevertheless necessary in reaching GHG reduction targets that will help limit global warming.

What are the sources of GHG emissions in Québec?

  • Transportation sector 43.3%
  • Industrial sector 30.5%
  • Residential, commercial and institutional sectors 10.3%
  • Agricultural sector 9.8%
  • Residual-materials management 5.8%
  • Electricity generation sector 0.3%

Source: Ministère du Développement durable, de l’Environnement et de la Lutte contre les changements climatiques. Data from 2017.

What is the breakdown of energy sources used in Québec?

Our clean, renewable electricity is the envy of the world. However, it represents only 35% of the total energy consumed in Québec. In other words, fossil fuels (natural gas and hydrocarbons from outside Québec) make up 65% of all the energy consumed. The time has come to use our clean energy to decarbonize Québec and drive its economic development.

Where does Hydro-Québec stand with regard to the energy transition?

Our Strategic Plan 2020–2024 outlines strategies that will help us continue to play a key role in implementing a low-carbon economy.

One of the plan’s objectives is to contribute to the reduction of GHG emissions across all our markets, particularly by encouraging the electrification of industrial companies and attracting new foreign companies that also want to decarbonize their activities or transition to a renewable energy source.

Our Strategic Plan 2020–2024, our interventions undertaken in the area of sustainable development and our corporate strategies are all perfectly aligned with the Québec government’s plan for a green economy, the Plan d’économie verte (PEV).

The plan’s objective is to help Québec reach its GHG emission reduction target, namely 37.5% less in 2030 than in 1990. How?

  • By electrifying Québec’s economy (transportation, industrial activities, buildings):
    • The transportation industry is already off to a good start. By developing innovative battery and motor technologies for electric vehicles, setting up a vast network of charging stations and generating clean, renewable power, Hydro-Québec is actively participating in the electrification of transportation.
  • By using energy and resources efficiently, in particular by maximizing energy efficiency in processes involved in planning, generating and consuming electricity.
