The following client identified a need for engineering design to rebuild their aging electrical system and make extensions to lines as needed to improve their infrastructure and potentially increase their service area.
As a regulated electric utility providing services to over 525,000 customers, approximately 1.25 million people, this client has a responsibility to provide high quality and efficient service to their customers. When they noticed deficiencies in the quality of their current electrical system, they reached out to ENERCON to provide the necessary design services to improve their current situation.
The project ENERCON supported consisted of four main components:
Task 1 – Rebuild 1.04 miles of existing Circuit 6671
The work consisted of the rebuild of approximately 1.04 miles of existing circuit 6671. The line was rebuilt as double circuit, monopole structures utilizing back-to-back post insulators. The existing 1351 ACSR “Dipper” conductor was transferred to the new structures while new 1351 ACSR conductor and OPGW shield wire was installed on the new circuit. Existing distribution and communication cables were transferred to the new structures.
The structures were designed utilizing the client’s standards and included development of: bill of materials, Plan and Profile drawings, structure loading/fabrication details, and stringing charts to be utilized for the construction of the line.
Task 2 – Rebuild 2.37 miles of existing circuit 6671
The work consisted of the rebuild of approximately 2.37 miles of existing circuit. The line was rebuilt as single circuit, monopole structures utilizing post insulators. The new structures utilize 1351 ACSR conductor and OPGW shield wire. Existing distribution and communication cables were transferred to the new structures.
The scope included the development of: bill of materials, Plan and Profile drawings, structure loading/fabrication details, and stringing charts to be utilized for the construction of the line.
Task 3 – Rebuild 1.65 miles of existing circuit 6610
The work consisted of the rebuild of approximately 1.65 miles of an existing circuit. The line was split and a double circuit loop was designed in and out of the existing substation utilizing monopole structures with post insulator design. The existing 636 ACSR “Swift” conductor was transferred to the new structures while new 1351 AAC “Columbine” conductor and 3/8” EHS shield was installed on the new circuit. Existing distribution and communication cables were transferred to the new structures.
The scope of design included the development of: bill of materials, Plan and Profile drawings, structure loading/fabrication details, and stringing charts to be utilized for the construction of the line.
Task 4 – 3mi x 6 mi Transmission Routing Study
The work consisted of conducting a routing study to find two feasible routes between the client’s existing substation and the existing tap. The study area consisted of a 3 mi by 6 mi corridor which included factors such as ecology, land use, cultural resources, and engineering to determine the best possible routes for the new transmission line.
Overall, ENERCON completed these tasks with high quality standards and an unwavering commitment to excellence. Each structure was designed to meet the specific standards of the client. This project demonstrated the ENERCON team’s ability to adapt to their clients’ needs and requirements while still upholding the overarching excellence standards of their company.
