Right of Way Requirement for Transmission System

Last Updated: January 20, 2017

A Right of Way (ROW) is an integral part of a transmission system (transmission lines, towers, sub-station etc.) that carry electricity. In other words, 
ROW is the strip of land immediately below and adjacent to a transmission line or tower. This is the strip of land used by Electrical Utilities to construct, operate and maintain the transmission line facilities."
 The obstacles like tall trees etc. have to be removed in the width of the ROW so as to prevent electric power outages.

As per the sub section 10 (b) of The Indian Telegraph Act, 1885, ROW is not purchased. The power utility in India only acquire the users right in the property under, over, along, across, in or upon which any transmission line or tower is placed. The ROW is used by the utility to construct, operate and maintain the transmission system. The owner of the land retains the ownership and use of land. The Act also states that the construction agency and the power utility will have to prevent un-necessary damage to the property during the construction as well as operation of the transmission system. They have to pay compensation for any damage to standing crops or fruit bearing trees as approved by the competent local revenue officers. In fact this is way leaves; means the right to use the property of another without possessing it.

The width of the ROW depends on the voltage of the transmission system and the height of the tower used. As per the rule, the ROW includes the area extending for a distance of 26 meter on each side from the centre of the tower for 400 kV transmission system and hence the ROW is 52 meter. The ROW requirements for transmission facilities of other voltages are:   

Transmission Voltage
Recommended Right of Way (ROW)
132 kV
27 m
220 kV
35 m
400 kV
52 m
800 kV
85 m
      
For technical and safety reasons, the following vertical clearances shall be maintained within the transmission line ROW.


Transmission Voltage
Minimum clearance between conductor and trees
132 kV
4.0 m
220 kV
4.6 m
400 kV
5.5 m
