About Us



This history of CST is rooted in the Midwest, as The Superior Group and Tri-City Electric Co. partnered to complete a large data center project beginning in 2013. As this collaboration was a success and we expanded our venture, Continental Electric of Chicago joined our partnership, forming CST, a Continental, Superior and Tri-City partnership in 2014.

CST is unique in that our venture is a collaboration of three of the largest electrical and technology firms in the region with an established tri-venture track record that dates back to 2013. Our venture is a singular partnership and entity in every sense. We pride ourselves on how our team works together to leverage our strengths for our customers.
