Crews from Harlan Electric upgraded the Bloomfield-Windsor Transmission line, renovating seven miles of double-circuit separations and realigning the line at the Rood Avenue Substation in Bloomfield. The project was divided into the following three phases: 

  • Phase 1, the 1777-1779 Transmission Line Double-Circuit Separation, for which Harlan Electric crews installed the foundation, structure, and wire for new  1.6-mile 115kV monopole line.  
  • During Phase 2, the 1777-1751 Transmission Line Double-Circuit Separation, we installed 49 monopole structures and transferred 5.3 miles of existing line conductor and optical ground wire. 
  • For Phase 3, crews installed the foundation, structure, and wire to cut the existing 1779 Transmission Line into the Rood Avenue Substation. 

Although the project took place under stringent environmental permitting requirements and a complex outage schedule, the project team planned and executed the work in a safe, efficient while maintaining the client’s schedule and budget goals.
