Irrican Hydro Project

Alberta, Canada

Klohn Crippen Berger (KCB) was retained to design a 7.0 MW run-of-canal hydro plant in southern Alberta on the St. Mary’s Irrigation System. The Project concept was to use the head across three canal energy dissipation drop structures, each 5 m-high, to construct a hydro plant that develops the total head of 15 m. KCB’s scope of services included concept through final design engineering services, preparation of procurement and contract documents, shop inspection QA/QC services and construction monitoring services.

Our design services included power and energy studies, structural, hydraulic and geotechnical design of the facilities, technical analysis and selection studies for the turbine-generator package including unit sizing and optimization, balance-of-plant mechanical and electrical equipment design and selection, preparation of the water-to-wire bid package and subsequent bid evaluation.

The bid evaluation resulted in the selection of a water-to-wire equipment package based around an S‑Type turbine unit and direct-drive generator. KCB designed an economic, functional powerhouse and intake to suit the selected equipment. The powerhouse design included an overhead traveling crane, a service bay for use by the Owner to support this and two other existing powerplants, as well as a control room that would be suitable for future use as a central control facility for operating all the Owner’s plants.
