Irrican Hydro Project

Klohn Crippen Berger 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. Klohn Crippen Berger'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 M&E 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. Klohn Crippen Berger 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.
