In a major development, Adani Transmission Ltd has reported the winning of two interstate power transmission projects under the tariff-based competitive bidding (TBCB) mechanism.
Both the projects were awarded by bid process coordinator PFC Consulting Ltd, and will be developed using the build-own-operate-maintain (BOOM) mode, under a concession period of 35 years.
The two projects – Khavda Bhuj Transmission Ltd and Karur Transmission Ltd – will involve capital expenditure of Rs.1,200 crore and Rs.200 crore, respectively. Both the projects essentially are meant for renewable energy evacuation.
The larger of the two, the Khavda-Bhuj project, will help evacuation of around 3 GW of renewable energy from the upcoming mega renewable energy park Khavda. On some 20,000 ha of land at Khavda (Bhuj district, Gujarat) is being planned a huge 3.5-GW hybrid solar-wind park.
Project scope
The Khavda-Bhuj project will involve the construction of 220 ckm of 765kV transmission lines connecting the Khavda and Bhuj pooling stations in Gujarat, and a 765kV GIS substation with transformation capacity of 4,500 MVA, at Khavda.
The Karur project will see the development of the 2x500MVA, 400/220kV Karur pooling station, proposed to be located between the Karur and Tiruppur wind energy zones, both in Tamil Nadu. The project will also entail construction of LILO (loop-in, loop-out) on both circuits of the 400kV double-circuit Pugalur-Pugalur (HVDC) line at Karur pooling station.
The Karur project has the distinction of being Adani Group’s first-ever ISTS power transmission project in Tamil Nadu.
Impact on portfolio
The two projects have taken Adani Transmission’s portfolio to over 18,500 ckm of transmission lines and 38,000 MVA of transformation (substation) capacity. Adani Group has targeted a power transmission portfolio of 20,000 ckm by 2022.
Evacuation of 66.5 GW
The Karur transmission scheme is part of the overall plan of providing ISTS-based evacuation infrastructure for 66.5 GW of upcoming renewable energy zones in Tamil Nadu, Andhra Pradesh, Karnataka, Gujarat, Rajasthan, Maharashtra and Madhya Pradesh. Out of this 66.5 GW potential, a total of 18.5 GW (Solar: 10 GW, Wind 8.5 GW) has been identified in the southern states of Tamil Nadu, Andhra Pradesh and Karnataka.
Very recently, ReNew Power won a TBCB concession—Narendra-Koppal–also related to renewable energy evacuation. (Read more)
