India, Gurugram: Power Grid Corporation of India Ltd (PGCIL) has suggested to use modern VSC technology for the proposed Leh power transmission scheme.
PGCIL has proposed to use voltage source converter (VSC) technology for the power transmission scheme, planned to support evacuation of 10 GW of renewable energy (mainly solar) from Leh, in the Union Territory of Ladakh.
PGCIL was mandated to prepare the detailed project report (DPR) for the scheme, and the same has been submitted to the Union power ministry.
It may be noted that PGCIL was mandated only for the DPR work. The implementing agency has not yet been decided by the power ministry. The project could be awarded to PGCIL on “nomination basis” under the RTM (regulated tariff mechanism) mode or it could very well be developed under the tariff-based competitive bidding (TBCB) route.
The Leh transmission scheme aims to evacuate 10 GW of renewable power through four ±350k V HVDC terminals.
There will be two separate transmission systems, each with a transfer capacity of 5 GW:
- Pang (UT of Ladakh) to Kathal (Haryana)
- Nyoma (UT of Ladakh) to Kashipur (Uttarakhand)
The double-circuit system will have 1,170 ckm of overhead AC lines, and around 30 km of HVDC cable.
There will be seven transition stations in the Leh region, supported by AC substation bays at Kaithal, Kashipur, Aligarh, Bareilly (both Uttar Pradesh) and Narela (Haryana).
