Ziro-based Power Grid Corporation of India Ltd (PGCIL) Chief Manager Nani Kojin said that the likely shutdown of the 132 kv transmission line could be for at least 15 days from the date of notice, to be issued shortly.
The districts likely to be affected are Lower Subansiri, Upper Subansisri, Kra Daadi, Kurung Kumey, East Siang, West Siang, Upper Siang and some parts of Papum Pare.
During the shutdown period, all feeder districts would have to make alternative power arrangements from their own ends, he said.
Tower no 12 located at Hoj-Potin area of 132kv Ranganadi-Ziro transmission line is in a vulnerable condition since long due to the road widening activities carried out by PWD (Highway) for the construction of Trans Arunachal-Highway.
Meanwhile, restoration work is going on in war footing for immediate shifting of the tower to safer location and to avoid power interruption to the eight districts.
