|Trans Mountain Corporation/EPCOR
|Burnaby, British Columbia to Edmonton, Alberta
The Trans Mountain Expansion is an engineering, procurement, and construction (EPC) joint venture between WPE and Kiewit that involves the installation of new pipeline and the use of existing pipeline between Burnaby and Edmonton. The project involves the design and construction of 14 different substation locations, two transmission lines, and over 30 distribution lines. System voltages vary from 138kV to 5kV, and the stations are comprised of a variety of air-insulated HV/MV equipment.
This project encompasses 980km of new pipeline, 193km of existing pipeline, and 12 new pump stations. This pipeline, designed to carry heavier oils or light crude oils, increases capacity from 300,000 barrels per day up to 890,000 barrels per day.
