Stantec Tapped for SunZia Transmission Project


Pattern Energy Group LP has chosen Stantec, a sustainable design and engineering company, to serve as owner’s engineer for the SunZia Transmission Project.

Part of the largest clean energy infrastructure initiative in United States history, the project, once complete, will provide the capacity to deliver 3,000 MW of energy to communities in Arizona and California – enough to supply 3 million people.

The SunZia Transmission Project is enabling Pattern Energy to develop up to 3,500 MW of wind power in New Mexico and then transport that energy to communities in the southwest U.S. The project includes the development of a 525 kV HVDC transmission system with overhead lines traversing approximately 550 miles of federal, state and private land between central New Mexico and central Arizona. It features a number of technological advancements in HVDC transmission, such as power and voltage ratings for voltage source converters and overhead lines, as well as the application of AC choppers.

Stantec will provide specialist HVDC owner’s engineer services for the SunZia Transmission Project, which includes electrical, civil, structural, building and mechanical engineering services associated with the HVDC converter stations and AC choppers. The scope of the project encompasses performing design reviews, interface management, witnessing factory acceptance tests for major equipment and commissioning assistance. Stantec has also been retained to provide OE services associated with the HVDC transmission line.
