The TELUS Len Werry Building in downtown Calgary houses offices, computer facilities, toll switch equipment, and local switching equipment for a major toll complex.

The project involves the replacement of the building's existing turbines with new reciprocating diesel generators and redundant synchronization switchboards in a new penthouse on top of the building.

HH Angus is providing electrical engineering services to support upgrades to the electrical distribution system related to the installation of the new diesel generators.
