PMTL is a 100% subsidiary of PowerGrid 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.
The project reached its peak construction in March 2020, but work was disrupted as India witnessed the lockdown due to COVID- 19. The project team with help of POWERGRID and local authority could restart the work gradually maintaining the mandatory COVID-19 protocol throughout the construction and the substation was operational in April 2021.
“We wish to congratulate POWERGRID for this successful commissioning and thank them for expressing confidence with Linxon. We also want to thank everyone who has been associated with this project, achieving the successful completion of the project in difficult times”, said Dinesh Chadha, Managing Director of Linxon in India.
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 the support of POWERGRID/PMTL it will be the first part of the system that could be commissioned.
