Name of the project

Innavik Hydroelectric Project


Innavik Hydro Ltd. Partnership (Pituvik Landholding Corporation and Innergex)

Expected date of construction

Fall 2019




10.3 km from the mouth of the Inukjuak River

Step of the procedure

  • Decision and authorization


The Commission has decided to authorize the project under certain conditions.


The Innavik project involves the development of a 7,5 MW hydroelectric generating station 10.3 km from the mouth of the Inukjuak River. The proposed site consists of a series of four natural vertical drops and the four rapids present a total vertical drop of 14.3 m over a distance of 2.7 km. The proponent maintains that this hydraulic resource will allow the community of Inukjuak to transition from using diesel and heating to this new renewable energy source.

The project includes the following permanent and temporary infrastructures:

Permanent Infrastructures

  • A hydroelectric power plant with an installed capacity of 7.5 WM;
  • Two Saxotype generating units located in a run-of-river plant;
  • A rockfill dam and and a spillway with a crest at 44.0 m designed to evacuate the 1,000-year design flood;
  • A trailrace excavated in the rock on the right bank, over a total length of 390 m, to channel turbined water back into the river below the rapids;
  • A spillway which the crest will have a width of 130.0 m and will be located at the 44.0 m level, i.e. the water level in normal operation. An excavated channel will allow the water to flow through the spillway durant plant operations;
  • Construction of a bridge across the Inukjuak River is also planned to provide access to the structures on the left bank. A section measuring 3,641 m will be built in order to do so;
  • A 25 kV transmission line installed on wooden poles along the access road to Hydro‐Québec’s existing switchyard north of the village of Inukjuak;
  • A transformer station built inside the plant and will consist of a 25 kV transformer.

Temporary Infrastructures

  • A camp, in the form of temporary trailers, with a surface area of 0.9 ha and an accommodation capacity of 128 persons;
  • Tree borrow pits with a total required land area of 30,3 ha;
  • A crusher/screen system;
  • A concrete batch plant;
  • A cofferdam installed upstream of the site’s main vertical drop and a diversion channel with a total length of 180.

The beginning of plant construction is planned for August 2019 and the plant commissioning is planned for fall 2020.

An update of the 2010 impact assessment was transmitted to the KEQC in February 2018 and provide more detail on the proposed development and present a description of the receiving environment, the expected impacts, the proposed mitigation measures, the information and consultation activities carried out by the proponent and a preliminary project schedule.


The beginning of plant construction is planned for August 2019 and the plant commissioning is planned for fall 2020.
