The Role of Rock Engineering in Hydroelectric Scheme from
Design to Operation
Dr. Marco Quirion, PhD, ing.
Hydro-Québec, Montréal, Québec, Canada
Abstract
Hydro-Quebec owns and operates more than 60 hydroelectric powerhouses and out of this number,
8 are excavated underground. From 600 dams owned by Hydro-Québec, 190 are categorized as
“large” dams under the ICOLD definition. The construction of all these hydroelectric schemes
required large volume of rock excavations: Powerhouse caverns, surface powerhouse enclosure,
spillway tailrace channels, unlined intake tunnels, access roads, to name a few. Also, for many sites,
high natural rock slopes are present in the vicinity of the installations. These plants were built over
many decades, going from the early 1930s up to the present day. Rock engineering is always
present in the lifecycle of these hydroelectric schemes from the design phases, through construction,
commissioning, and their safe operation. The goal of this webinar is to share Hydro-Quebec’s
experience on the different aspects of rock engineering in the context of hydropower.
