Carillon Generating Station Rehabilitation and Retrofit

The Carillon generating station, built in 1962, produces some 753 MW of energy. Many of the original pieces of equipment were at the end of their useful life and needed be completely rehabilitated and retrofitted.

Our Client’s Challenge

Hydro-Québec constructed a significant portion of its hydroelectric generating stations in the 60’s. Given the state of certain stations, it began planning the rehabilitation and retrofit of several of these projects over the next few decades. One of the first stations to be rehabilitated was the Carillon generating station. Hydro-Québec chose partners for this project based on high criteria: ones who shared the same expectations for high-quality work, were attentive and possessed the ability to adapt.

Our Approach

This project required close co-operation to meet a critical schedule. Thus, WSP favored a multidisciplinary and integrated approach, relying on the size and talent of our team as well as the range of services that we provide –a one-stop solution to Hydro-Québec’s various needs. 

Within this context, the complete range of required services were provided to the client without third party support. From underwater inspections, rope access assessments, or niche technical consulting services targeting turbine-generator units and hydromechanical component – services were provided directly by members of the WSP Team which ensured rapid response, alignment and tight quality controls. 

Our Services

The team’s multidisciplinary disciplines were showcased thanks to the various mandates conducted by WSP as part of the Carillon generating station rehabilitation and retrofit project. The services provided include:

  • Studies as well as production of plans and engineering specifications;
  • The contribution of technical teams specialized in niche disciplines specific to the hydroelectric field, such as turbine-generator units, hydromechanics (gate, hoist, screen, stoplogs, etc.), hydraulics, electricity, structural and civil engineering);
  • The contribution of teams as part of high added-value associated work to the rehabilitation and retrofit works, such as the underwater inspection, rope access assessment, and health and safety teams;
  • Effective coordination of all the stakeholders.
