Primary was contracted by FortisAlberta to estimate and design both overhead and underground powerlines for the Wolf Midstream plant, providing 25 kV up to 18 MVA of new service. Our construction crew also completed the construction of overhead powerlines. Initially, the project scope involved a single circuit of a three-phase powerline with a neutral wire. However, considering reliability concerns and the need for uninterrupted plant operations, the project was upgraded to double-circuit powerlines.

During the project, we faced challenges meeting the client’s high load demand. To overcome this, a suitable substation capable of handling the required power usage was identified. Upgrading and reconstructing the existing lines with larger conductors allowed us to connect the substation to the site. This involved creating new overhead and underground alignments, and navigating river crossings with two circuits of three-phase configurations. We successfully executed crossings of an underground AltaLink transmission line in three locations and installed an underground system to cross CN railway tracks at two locations.

Despite challenging weather conditions, the Primary design and construction teams collaborated seamlessly, overcoming obstacles and successfully completing the project on schedule.
