Three Sisters Underground Conversion
At the Three Sisters Mountain Village Resort in Canada's Rocky Mountains, we converted two overhead transmission lines to underground high-voltage cable encased in concrete duct banks. Construction challenges included abandoned shallow mineshafts, sinkholes and special wildlife precautions. Client: Three Sisters Mountain Village

AltaLink 500 kV Upgrades
We are providing front-end services and EPC delivery for AltaLink's 500 kV upgrades in the province of Alberta. Three substations have been upgraded to 500 kV voltage, and options are under review for the 350 km transmission line between Edmonton and Calgary.Client: AltaLink LP

Gulf Cooperation Council Interconnection
We are owner's engineer on a project to interconnect the power systems of Bahrain, Kuwait, Qatar and Saudi Arabia. The project involves 800 km of new transmission lines, six new substations, an undersea cable, and a converter station linking 50 Hz and 60 Hz grids.

Turnkey Greenfield Substations
Turnkey EPC delivery of five greenfield substations in the province of British Columbia. Substations include voltages from 60/25 kV to 230/25 kV in locations near Whistler, Maple Ridge, Surrey, Fort St. John, and Abbotsford. Construction challenges included mountainous terrain and tight project schedulesCountry: Canada

240 kV Pole Replacement
240 kV transmission towers were relocated to accommodate road widening in the city of Calgary. Very limited outages were available, so much of the replacement work was conducted under "hot" conditions with cranes holding energized lines away from the tower installation site. A unique laminated pole was designed to minimize the tower footprint; at the time of its construction it was the tallest of its kind in North America.

Cordel Hansman Transmission Line and Substation
Engineering, procurement, and construction of 103 kilometres of new 240 kV transmission line, a new 240/25 kV substation, and a rebuilt 240/25 kV substation in Alberta. Sensitive environmental conditions required winter construction and a challenging schedule that minimized outages on local communities and industries.
