Indian players bag projects under GEC through TBCB mode [free access]

August 2, 2019

Indian state-owned interstate network developer, Power Grid Corporation of India (POWERGRID), and two private network developers have been awarded transmission projects for connecting renewable energy (RE) capacity under the Green Energy Corridor (GEC) project.


In the recent biddings, five power-transmission projects have been awarded via the tariff-based competitive bidding (TBCB) mode. These projects will be developed on a build, own operate and maintain (BOOM) basis, and have a concession period of 35 years.


POWERGRID and Adani Transmission Limited (ATL)—a power transmission arm of India-based conglomerate Adani Group, have bagged two projects each, while Sterlite Power Transmission Limited (SPTL) bagged one. The winners have been issued a letter of intent for these projects.


POWERGRID’s projects include the ‘Transmission System for providing connectivity to RE projects at Bhuj-II (2,000 MW) in Gujarat’, which includes a 765/400 kV gas-insulated switchgear (GIS) substation and 765 kV lines that traverse the state of Gujarat. The project aims to strengthen the grid evacuation infrastructure in western India and improve electricity access to important demand centres.


The second project includes the ‘Transmission system associated with long-term agreement (LTA) applications from Rajasthan solar energy zones (SEZ) (Part-C)’. This comprises establishment of 2x1,500 MVA, 765/400 kV substations at suitable locations near Khetri with 2x240 MVAr, 765 kV and 1x125 MVAr, 400 kV bus reactors, 400 kV Khetri–Sikar line, 400 kV line bays at Sikar substation for the 400 kV Khetri–Sikar line, 765 kV Khetri–Jhatikara line, 765 kV bays at Jhatikara for the 765 kV Khetri–Jhatikara line, 1x240 MVAr switchable line reactors for each circuit at the Jhatikara end of the 765 kV Khetri–Jhatikara line, along with reactor bays.


ATL’s projects include construction of the 480-circuit km-long, 765 kV Bikaner–Khetri double-circuit line under the ‘Transmission System Associated with LTA Applications from Rajasthan SEZ (Part-D)’. The second project involves 272-circuit-km-long, 765 kV line under the ’Western Region Strengthening Scheme (WRSS-21) (Part-A) – Transmission System Strengthening for Relieving Over-loadings Observed in Gujarat Intra-state System due to RE Injections in Bhuj Pooling Station (PS)’ project.


Reportedly, this growing participation from private players has brought down the project costs by about 40-50 per cent.
