Chandauti 400 kV AIS substation, India

Linxon is supplying a 400 kV AIS substation at Chandauti (Gaya) in the state of Bihar located in the eastern part of India for POWERGRID Mithilanchal Transmission Limited (PMTL).

PMTL is a 100% subsidiary of Power Grid Corporation of India Ltd (POWERGRID), which is the largest state-owned transmission utility of India. This substation is part of a network comprising of three more substations and transmission lines also being constructed by PMTL. Chandauti has been the first segment in this network to be commissioned.

The 400/220/132 kV, 3x 500 MVA Chandauti substation consist of 14 bays of 400 kV, 12 Bays of  220 kV and 8 bays of 132 kV, constructed as a part of India’s EASTERN REGION STRENGTHENING SCHEME (ERSS) to meet the load demand of the state of Bihar up to 11000MW.

Power demand in the state of Bihar is expected to increase substantially in the upcoming years which will require substantial investment in their transmission system.  Detailed load flow studies have indicated the need for two new 400/220/132kV substations in North Bihar at Sitamarhi and Saharsa and one 400/220/132kV substation in South Bihar at Chandauti (Gaya) along with augmentation of the 400/132kV Motihari substation. The Chandauti substation will play an important role in supporting the network and with support of POWERGRID/PMTL it will be the first part of the system that could be commissioned.
