IndiGrid Secures Transmission Projects from REC, 1,000 Cr. Estimated CapEx

IndiGrid Trust has received Letters of Intent (LoIs) for developing two greenfield Inter-State Transmission System (ISTS)-connected projects from REC Power Distribution Corporation Ltd. (RECPDCL). These projects will be developed at a total estimated cost of Rs. 1,000 crore.

This information was conveyed by IndiGrid via a stock filing dated 2nd January 2024.

Both Transmission Projects to be Built by IndiGrid Trust in 24 Months

IndiGrid has won the projects for ‘evacuation of power from the Dhule 2GW Renewable Energy zone’ and ‘establishment of the Western Region Expansion Scheme XXXIII (WRES-XXXIII) Part-C’ through Tariff-Based Competitive Bidding (TBCB). Both these projects have a specified construction period of approximately 24 months, and they will be developed on Build, Own, Operate and Transfer (BOOT) over 35 years.

Evacuation of Power from Dhule 2 GW RE Zone

RECPDCL’s Request for Selection (RfS) for this project, dated 22nd May 2023, specifies the installation of 4 Inter-Connecting Transformers (ICTs) of 500 MVA capacity each to step down the voltage from 400 KV to 220 KV at the greenfield Dhule Pooling Substation. Apart from this, the substation is to be equipped two bus reactors of 125 MVAr capacity each. The project also includes the laying of 400 KV Dhule Pooling Station – Dhule (BDTCL) Double Circuit (D/c) transmission line.

While RECPDCL’s document stated the length of this transmission line as about 60 Km, IndiGrid stated that it would be laying about 70 Km of 400 KV D/c line for this project.

IndiGrid also specified that this project will have annual transmission charges of about Rs. 53 crore once it is commissioned.

Western Region Expansion Scheme XXXIII (WRES-XXXIII) Part-C

The second mandate secured by IndiGrid falls under part C of the Western Region Expansion Scheme XXXIII (WRES-XXXIII).

Scope of work in this project includes the establishment of a 765/400 KV substation with 2×1500 MVA capacity, and a 400/220 KV substaion with 2×500 MVA capacity in Madhya Pradesh. The former substation will be equipped with 1×330 MVAr, 765 KV bus reactor, while the latter will have a 1×125 MVAr, 420 KV bus reactor.

Apart from this IndiGrid will be laying Loop In Loop Out (LILO) for one circuit of the 765 KV D/c line at Ishanagar, MP. The approximate length of transmission line to be laid under this project is 18 Km.

The substations are designed to cater to the electricity demand of the proposed green hydrogen plant in the nearby area, loads in Chhatarpur, Tikamgarh & Jatara areas and for interconnection of 630 MW NTPC Barethi Solar Plant”, stated IndiGrid’s release.

IndiGrid has stated annual transmission charges as Rs. 62.5 crore from this project.
