AltaLink Western Alberta Transmission Line (WATL) HVDC Project

AltaLink Western Alberta Transmission Line WATL HVDC Project

The Western Alberta Transmission Line (WATL) is Alberta’s first in-service HVDC transmission system linking the major centres of Edmonton and Calgary.

The project improved transmission system reliability, reduced system congestion, and saves over 350,000 tonnes of carbon emissions per year from entering the atmosphere – the equivalent of removing 65,000 vehicles from Alberta’s roads.

Teshmont was engaged by AltaLink to act as the project’s Owner’s Engineer for the 2000 MW, 500 kV Line Commutated Converter (LCC) HVDC project. Teshmont provided a broad and comprehensive range of engineering services, from determining equipment ratings through to assistance during system start up and commissioning.

The project required Teshmont to review the AESO Functional Specification, and develop a detailed Technical Specification for the HVDC converter equipment and EHVAC switchyards associated with the converter equipment. The specification included system studies, design, manufacture, factory testing, supply, delivery to site, installation, site testing, commissioning, provision of documentation and drawings, training and warranty of the 500 kV converter stations and associated 240 kV ac switchyard equipment. Teshmont also provided critical project support, including technical tender evaluations, contract negotiation, studies, and related testing and commissioning assistance for the protection and control system.

Teshmont was awarded the 2016 Association of Consulting Engineering Companies (ACEC) Manitoba “Award of Excellence” in the Energy Resource Development category for our work on this project. An Award of Excellence is the highest award possible within a category, and recognizes outstanding achievement in consulting engineering.
