Sterlite Power Commissions Gurgaon Palwal Transmission Project Worth INR 1027 C

Sterlite Power, a leading global power transmission player, today announced the commissioning of Gurgaon Palwal Transmission Project (GPTL) worth INR 1027 Cr, that will enhance the power capacity of Gurugram and Palwal areas in the state of Haryana by ~2000 MW.

Envisaged as part of the Inter State Transmission System project, the Gurgaon Palwal Transmission Project (GPTL) will meet the peak energy requirements of Haryana, which is expected to reach more than 12000 MW in FY 20-21 from 9000 MW in 2014-15. The project will evacuate ~2000 MW to HVPNL (Haryana Vidyut Prasaran Nigam Ltd.) ensuring access to reliable power for more than 3 million households in the state.

With more than 10,000 high capacity diesel generation (DG) sets installed in Gurugram, the project will play a pivotal role in minimizing their usage and subsequent reduction in pollution levels brought on by combustion of diesel.

Commenting on this significant milestone, Pratik Agarwal, Managing Director, Sterlite Power, said, “We are proud to have completed the GPTL project which will help bring 24x7 power to Gurugram area. This project will not only benefit the people of Haryana by providing reliable power supply but will also bring cleaner air to NCR by reducing the use of diesel fired generator sets.” 

The project consists of, four 400kV double circuit transmission lines with total length of 143 kms, 3 Gas Insulated Substations (GIS) at Prithla, Kadarpur and Sohna Road, 2 bay extensions at Dhanonda and a LILO connecting the 400kVDC Gurgaon-Manesar transmission line. The company had won this project through tariff-based competitive bidding process and executed it under the Build, Own, Operate and Maintain (BOOM) model.

The project implemented one-of-its-kind innovation with India’s first vertical GIS substations being built at Prithla, Kadarpur and Sohna. These 400/220kV GIS substations are multi-storied substations with a rooftop 220kV open switchyard. A conventional GIS substation of similar capacity generally requires 12 acres of land, but this innovative solution is built only on 3.8 acres resulting in 75% reduction in land size.  Apart from the vertical substations, Multi Circuit Monopole towers have been built to optimize the space challenges related to the project. Apart from saving land, all these innovations have resulted in offsetting more than 18,000 tons of CO2 emissions each year as compared to a conventional layout for a similar GIS substation.
