Transmission, Distribution & Collection

Transmission, distribution and collection structures form the infrastructure of the nation’s electric grid, carrying electricity between generation sites to substations and eventually end users. They come in a variety of shapes and sizes, all of which must be customized to the site and application they are being used for. Inside the fence of a substation, support structures and a well graded pad ensure the longevity of these critical facilities.

Halker’s capabilities in civil and structural engineering include a wide range of power installations, including civil plans for substation sites, substation support-structure design, and overhead and underground transmission, distribution and collection line design.


Electric substations are one part of an electrical generation, transmission, and distribution system, transforming voltage and performing a range of other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels, so substations need to include transformers to change voltage levels between high transmission voltages and lower distribution voltages, or at the interconnection of two different transmission voltages.

With this need in mind, our electrical engineers are experts in utility build-outs, including electrical power distribution system assessment and design. Our substations are designed with safety and efficiency first and foremost, creating facilities that function for our clients over the long term.
