Project Need

  • Both transmission lines are wood H-frame construction with poles dating back to the 1950s. Nearly every structure has significant corrective maintenance/aging infrastructure concerns (degraded pole shafts, arms and tops; bird holes, degraded hardware etc.) 
  • Installing self-supporting steel poles will significantly reduce the quantity of future corrective maintenance work orders as a result of bird holes, broken arms, degraded poles and hardware) 
  • Replacing wood poles with steel poles will also help to eliminate bird nesting on the structures. Bird nesting can cause electrical outages
  • Rebuilding the transmission line will reduce the quantity of structures by approximately 50%.  This will reduce the quantity of ground inspections and will eliminate the inspection/treatment of over 80 wood poles

Project Description

  • Rebuild two single-circuit 115 kV wood H-frame circuits as one double-circuit steel monopole line
  • New structures (42) will be tubular steel on concrete drilled pier foundations
  • Overall project length is approximately 4 miles (84 existing structures)
  • This project is subject to PSC approval and design changes
