THIRUVANANTHAPURAM: A 220 KV Gas Insulated Substation (GIS) will be launched exclusively for Vizhinjam international transhipment terminal on Thursday. Though the launch of the 220 KV substation was included in the 100 days programme of the LDF Government, the reality is that the KSEB does not have a direct role in it. Power is being drawn from Kattakada substation belonging to the KSEB which is a good 20 km away from Vizhinjam and is meant exclusively for Adani Port in Vizhinjam.
