With over 150 substations completed, Great Southwestern Construction has continued a tradition of excellence in all phases of substation and switchyard construction projects.

We perform substation and switchyard construction from the ground up including engineering, material procurement, site work, foundation construction, grounding systems, steel erection, bus work installation, welding, power and control cable installation, testing, and finish rock for stations through 500kV.

We’ve also performed Static Var Compensation Stations and stations requiring sophisticated Dynamic Var Systems and Capacitor Bank Systems on 345kV stations.

Our substation project managers are all highly experienced not just in substation construction but in building customer alliances. Communication, cooperation, problem solving and flexibility are why we are considered to be the contractor of choice for many of our customers.
