NTPC L-150 Anchor Inspection and Rehabilitation Project, Highway 5
This is a non-designated project on federal lands or outside Canada. The listed authorities are responsible for the project assessment.
NTPC is currently planning an anchor degradation study for the L-150 transmission line starting September 2022. The L-150 is a 115 kV transmission line forming the South Slave Grid, comprising of approximately 800 Guyed-Y aluminum transmission towers. Additional geotechnical information is required to complete Engineering of the anchor solution, and ground level assessments of all the anchor structures is required to prioritize structure rehabilitation. NTPC is planning to investigate the anchors and identify the main cause(s) of anchor degradation along the Transmission Line (Corrosion, End of Life, etc.) and the extent of the degradation during the fall of 2022. The scope of work involves subsurface excavation (2-3 m) to determine extent of surface & subsurface corrosion, for one anchor at several tower sites.
