Bihar State Power Transmission Company Limited, the State Transmission Utility (STU) formed after unbundling of the erstwhile Bihar State Electricity Board, is working under the aegis of Govt. of Bihar and a subsidiary company of Bihar State Power (Holding) Company Limited.

Bihar State Power Transmission Company Limited is intensifying its network capabilities through continuous planning, timely execution, rigorous operation and maintenance of Intra-State Transmission System in coordination with the Central Transmission Utility (CTU) and various other bodies.

The remarkable benchmark achieved by BSPTCL in the power transmission sector vis-à-vis contributing in Nation building are as follows:-

  • BSPTCL is operating a transmission network comprising 152 Grid Sub-stations (2 Nos. of 220/132 kV GSS, 22 nos. of 220/132/33 kV GSS and 128 nos. of 132/33 kV GSS) having transformation capacity of 9850 MVA (at 220/132 kV) & 15790 MVA (at 132/33 kV) & 5103 CKM of 220 kV and 12182 CKM of 132 kV transmission lines to cater load demand of remotest area of the State and thus achieving the organization goal of Quality Power for All.

    By the end of FY 2023-24, BSPTCL is likely to have 165 Grid Sub-stations with transformation capacity of 1000 MVA, 9640 MVA and 17960 MVA at 400/220 kV, 220/132 kV and 132/33 kV levels, respectively. Bihar Grid Company Limited (BGCL), a joint venture between Bihar State Power Holding Company Ltd (BSPHCL) and Power Grid Corporation of India Limited (PGCIL) is also contributing in achieving the goal. Capacity augmentation at 400/220 kV is the thrust area. The majority of existing 400 kV systems are owned by Power Grid Corporation of India Limited (PGCIL). BSPTCL is constructing 400/220/132 kV Grid Sub-station at Bakhtiyarpur for the first time. Apart from this, BGCL is also constructing two more 400/220/132/33 kV Grid Sub-stations at Jakkanpur and Naubatpur with associated high capacity transmission lines resulting in total transformation capacity of 15390 MVA at 400/220 kV level in Bihar with CTU by the end of FY 2023-24.

  • GIS (Geographical Information System) mapping of all its operational as well as under construction Grid Sub-stations has been done and information is available on company’s website.
  • Unified Load Dispatch & Communication (ULDC) has upgraded the SCADA system installed in SLDC. Optical fiber link has been established throughout the transmission network for ensuring faster communication of real time data flow.
  • BSPTCL has adopted e-Office which is a Mission Mode Project (MMP) under the National e-Governance program of the Government. The product is developed by National Informatics Centre (NIC) and aims to usher in more efficient, effective and transparent inter-government and intra-government transactions and processes.
  • Enterprise resource planning (ERP) has been implemented which has integrated varied organizational systems and facilitates for error-free transactions and production thereby enhancing the organization's efficiency in its intra state power transmission business.
