Bid process coordinator PFC Consulting Ltd (PFCCL) has extended the last date of submission of technical and financial bids for an ISTS scheme in Karnataka.
PFCCL, in a recent notice, said that the last date for submission of RfP bids (both technical and financial) stands extended to August 16, 2023 from July 17, 2023 earlier.
The scheme in question is officially termed as “Transmission scheme for integration of Renewable Energy Zone (Phase-II) in Koppal-II (Phase-A & B) and Gadag-II (Phase- A) in Karnataka”.
In another related development, PFCCL recently incorporated a project special purpose vehicle named “Koppal II Gadag II Transmission Ltd” to carry out pre-project works before it is handed over the successful bidder under the tariff-based competitive bidding (TBCB) mechanism.
According to information available with T&D India, the aforementioned transmission scheme has two components:
- Transmission scheme for integration of Renewable Energy Zone (Phase-II) in Koppal-II (Phase-A) and Gadag-II (Phase- A) in Karnataka [Estimated Cost: Rs.2,564 crore; Completion: 24 months]
- Transmission scheme for integration of Renewable Energy Zone (Phase-II) in Koppal-II (Phase-B) in Karnataka [Estimated Cost: Rs.1,881 crore; Completion: 36 months]
At the 10th meeting of the National Committee on Transmission (NCT), it was proposed that both the components would be clubbed for bidding purposes (selection of developer) with an implementation timeframe of 24 months and 36 months, respectively.
The main elements of the transmission scheme, considering both components, include:
- 765/400kV, 2×1,500 MVA, 400/220kV, 2×500 MVA Koppal (Phase-A) Pooling Station
- 765kV double-circuit line from Koppal-II PS to Narendra (New) PS
- 400/220kV, 2×500 MVA Gadag-II (Phase-A) Pooling Station
- 400kV double-circuit line from Gadag-II PS to Koppal-II PS
- 765kV double-circuit line from Koppal-II PS to Raichur
This two-phased transmission scheme will facilitate integration and evacuation of 1 GW potential each at Koppal-II and Gadag-II renewable energy zones (REZ). It may be noted that through this scheme, Gadag-II REZ is being integrated with Koppal-II PS, through transmission element #4 discussed above. It is also learnt that connectivity applications of about 900 mw (400 mw at Koppal-II and 500 mw at Gadag-II) have already been received.

Overall objective
The subject transmission scheme is part of the overall transmission infrastructure planned for the evacuation of about 11 GW of renewable energy from Karnataka, concentrated mainly in Gadag, Davangere, Bijapur, Bellary and Tumkur.
The southern state has a total renewable energy potential of 17 GW. Given the inherent capacity utilization of solar and wind plants, the total evacuation is expected to be around 12.5 GW. Karnataka is also planning battery energy storage systems (BESS) worth 3 GW. Considering all this, evacuation infrastructure corresponding to around 11 GW has been planned.
