Storm Restoration from June 29, 2012 Derecho
On June 29, 2012, a storm called a Derecho, completely demolished three Transmission towers, and severely crippled a fourth tower. This 500 kV Transmission Line is a critical link to the East Coast Power Grid. It funnels much needed generation from the big generating plants on the Ohio River to the East Coast. With the temperatures soaring well over one hundred degrees for several days, getting this line back in service is super critical to the Power Grid. Bundle conductors at each location were severely damaged. Major repairs including many full-tension splices had to be completed.
First Energy dedicated significant resources to quickly restore this Transmission Line to service. There were many Power Company employees and Contractors working together to make this project a huge success. The total process started with mobilization on Saturday, the line energized on Thursday, and mobilization to other damaged Transmission Lines on Friday. With focus, determination, and professionalism, C.W. Wright Construction was able to attack this catastrophe.

The overhead portion of the Project was for installing seventy-seven (77) engineered galvanized steel structures and their accompanying foundations. The underground portion was dual circuit duct bank, manholes & termination structures.
Suffolk to Thrasher 230 kV
This Dominion Virginia Power Project involved the installation of pipe pile foundations and the construction/rebuild of approximately 22 miles of 230 kV overhead transmission line from Suffolk Substation to Thrasher Substation.
