Transmission line construction requires a large workforce as well as significant quantities of material and equipment. Different stages of construction will take place at different times depending on your location along the transmission line right-of-way.
- Workspace preparation and materials delivery
The right-of-way and structure locations must be prepared for work and building approaches to access the land, including removing trees/vegetation as needed. Structure materials are delivered to work sites. - Foundations
Foundations for the structures are installed. They may be concrete, screw piles or driven piles. - Structure assembly
The structure is assembled in sections either on the right-of-way or in a staging yard. - Structure erecting
The structures are erected using cranes or helicopters. - Structure Stringing
Transmission line wire (called conductor) is delivered and attached to the structures. Cranes or helicopters may be used to string the conductor. - Line Work
The wires may be fused together using implosive connectors, which produce a loud explosion. on days when this work is scheduled. - Energization
Quality and safety inspections are completed and the new transmission line is energized and connected to Alberta’s grid. - Reclamation
Reclamation and clean-up begins once the transmission line stringing is complete. We aim to return the land to its previous condition after one post-construction growing season.
