The OHTL will be operated & maintained by National Electric Grid Uzbekistan (NEGU). 
Dedicated/full-time personnel are not required for this purpose, however, both preventive & 
corrective maintenance will be undertaken at the OHTL.
Preventive Maintenance includes works at tower foundation, monitoring of earth resistance 
values, tree cutting and trimming along the ROW, ground patrolling, thermo-vision scanning 
on sample basis and attending to defects if any. Corrective Maintenance depends on type 
of issues. 
The OHTL will be designed to facilitate workers for maintenance activities including activities 
such as tower painting, upgrade in the future, inspections, replacement of insulators, 
strengthening of tension ropes, etc.

A Right of Way is a passive but critical component of transmission line. It provides a safety 
margin between the high-voltage lines and surrounding structures and vegetation. It also 
provides a path for ground-based inspections, access to transmission towers and other line 
components if repairs are needed. The width of Right of Way for the proposed 500kV OHTL is

considered to be 85m. This accounts for the 30m buffer zone on each side of the OHTL as 
required by law and a wire zone of 25.6m. See figure below.
