Summaries of environmental knowledge
In the context of its power generation and transmission projects, Hydro-Québec has carried out environmental impact studies for many years. The company has developed expertise in environmental matters that is now used in the design of new projects. Here are complete reports that provide a review of the knowledge acquired over the past 50 years with regard to the natural environment and the human environment. It also presents measures to mitigate environmental impacts.
Québec Hydropower Generation and the Environment – December 2020
With a long history of developing and operating hydropower infrastructure, Hydro-Quebec generates large volumes of low-carbon electricity to meet clean energy demand in Quebec and neighboring markets. Quebec hydropower has particular features that distinguish it favorably from other hydropower generation sources and its environmental performance is comparable to other renewable energy options. Thanks to the specific characteristics of the environment in which it develops its projects and its ever-evolving knowledge and expertise, Hydro-Quebec is in a position to deploy effective mitigation and compensation measures to reduce or manage the environmental and social impacts of its hydropower fleet.
Through this report, Hydro-Quebec provides factual evidence concerning Quebec hydropower, supported by science and resulting from rigorous environmental compliance monitoring programs conducted over the last few decades. The reader will also find the most up-to-date evidence relating to the effectiveness of the many mitigation measures Hydro-Quebec has put in place. The company has never published such a comprehensive review.
