Bihar State Transmission Company Ltd. (BSTCL) has floated tenders for various electrical works worth a cumulative amount of Rs. 312.12 Crore, and a completion period of 18 months.
This substation will step down the voltage from 220 KV to 132 KV, and then further to 33 KV. This tender also specifies a Substation Automation System (SAS) at the Tajpur GSS, and associated residential quarters.
Another tender involves the construction of a similar GSS at Thaurganj in Bihar’s Kislianganj district. This too will have transformers of the same power capacity as the Tajpur Substation (2 x 160 MVA and 3×50 MVA) and will handle the same voltages (220/132/33 KV).
Other than these two substations, BSTCL has also invited bids for laying a 39 RKM long, 220 KV D/C transmission line from PGCIL Banka to BGCL Goradih with Aluminium Conductors Steel Reinforced (ACSR) Zebra Conductor.
