India, Khavda: HVDC power transmission infrastructure to be used for a Khavda Renewable Energy (RE) zone evacuation scheme in Gujarat.
Significant power transmission infrastructure involving HVDC technology has been envisaged for a major evacuation scheme related to the Khavda Renewable Energy (RE) zone in Gujarat.
The ISTS scheme, officially known as “Transmission system for evacuation of power from potential renewable energy zone in Khavda area of Gujarat under Phase-V (8 GW),” was reviewed at a recent meeting of National Committee on Transmission (NCT).
The scheme entails HVDC infrastructure at both ±500 kV and ±800 kV levels. The two major components (Part A and Part C) will be developed under TBCB modality, while a small component – Part A1 – will be implemented under the RTM (regulated tariff mechanism) route by Power Grid Corporation of India Ltd (PGCIL).
Part A will involve the 6,000 MW, ±800 kV KPS2 HVDC [LCC] terminal station in Gujarat, and an identical station at Nagpur in Maharashtra. Connecting the two will be a 1,200 km HVDC bipole line capable of evacuating 6,000 MW.
Part C will mainly include the 2,500 MW, ±500 kV KPS3 HVDC [VSC] terminal station and the 2,500 MW, ± 500 kV KPS3 HVDC [VSC] terminal station, both in Gujarat.
Part B of this scheme involves augmentation of transformation capacity at the two GIS substations — KPS2 and KPS3. Since this augmentation will require infrastructure envisaged in Part C to first come up, Part B will be deliberated upon only after completion of Part C.
Transmission system for the evacuation of 15 GW of power from the Khavda RE Park in Gujarat has evolved under three phases (Phase-I: 3 GW, Phase-II: 5 GW and Phase-III: 7 GW). Phase-I and Phase-II are under construction while Phase-III is under bidding. In view of large number of connectivity applications received, Phase IV (7 GW) and Phase V (8 GW) have been planned with a view to set up a total 30 GW of evacuation from the Khavda RE park.
