Hydro-QuÃ©bec put into service new transmission facilities built as part of the 735-kV Chamouchouane—Bout-de-l’ÃŽle project.
More than 1,250 people participated in the construction of some 1,000 towers since 2016, according to the utility. The project has also resulted in $1.1 billion in economic spinoffs in specialized services and the purchase of goods and materials in the province.
The project’s three components include:
“- A new 735-kV transmission line 420 km long between Chamouchouane substation in La DorÃ©, Saguenay—Lac-Saint-Jean, and the MontrÃ©al metropolitan loop.
“- The 735/120/25-kV Judith-Jasmin substation, located in Terrebonne and connected to the new line. The substation will meet the needs of both the 735-kV main transmission system and regional and local demand.
“- A new 19-km segment of the 735-kV line to supply Bout-de-l’ÃŽle substation in MontrÃ©al.
Some figures for the Chamouchouane—Bout-de-l’ÃŽle project:
“- $1.3 billion total cost
“- 5,040 km of conductors (cables transporting energy) installed
“- 1,000 towers erected
“- 33,000 tonnes of steel used
“- 2,500,000 construction hours
According to the utility, thanks to these new facilities, power losses on the Hydro-QuÃ©bec transmission system will decrease considerably, whereas operating flexibility will increase, and this, to the benefit of all customers.
