In order to facilitate integration of large scale renewable generation capacity addition, a comprehensive scheme including Intra-State and Inter-State transmission system has been identified as a part of ‘Green Energy Corridors’.
For the funding of green energy corridors in both intra and inter State transmission projects, under the framework of cooperation between Govt. of India and Govt. of Germany, KfW Germany is providing soft loan to the tune of Euro 1 billion.
Intra-State Transmission System is being implemented by respective State Transmission Utilities (STU) and Inter-State Transmission System is being implemented by Power Grid Corporation of India Ltd. (PGCIL), said Union Minister for State (IC) for Power, Coal, New & Renewable Energy and Mines, Piyush Goyal.
Intra State transmission schemes under Green Energy Corridors (GEC) are to be funded as 20 percent equity of the State Govt., 40 percent grant from National Clean Energy Fund (NCEF) and 40 percent soft loan, whereas, the inter State transmission schemes are to be funded as 30 percent equity by PGCIL and 70 percent as soft loan, he added.
For Inter-state transmission projects pertaining to Part A, B and C of Green Energy Corridor, loan agreement for financial assistance of Euro 500 million from KfW, Germany has been signed by PGCIL and the projects are likely to be completed by 2018. Further, for implementation of transmission schemes under Green Energy Corridor-Part D, PGCIL has taken loan from ADB.
For Intra-state transmission projects under Green Energy Corridor; the States of Tamil Nadu, Rajasthan, Himachal Pradesh, Andhra Pradesh, Gujarat and Madhya Pradesh have signed the loan agreements from KfW, Germany for financial assistance of Euro 76 million, Euro 49 million, Euro 57 million, Euro 68 million, Euro 114 million and Euro 124 Million respectively.
In order to integrate solar parks with the grid, Ministry of Power assigned PGCIL to implement Inter-State transmission scheme for evacuation from 8 solar parks (7200 MW).
Transmission scheme for 6 solar parks (5750 MW) is already under implementation [Ananthapuram (1500 MW), Pavagada (2000 MW), Rewa (750 MW), Bhadla-III (500 MW), Bhadla-IV (250 MW), Essel Saurya (750 MW)]. Tender issued for Banaskantha Solar Park (700 MW), whereas Long Term Access (LTA) application for other MP solar park from the developer is awaited.
To evacuate power from the renewable capacity addition in renewable rich States (Andhra Pradesh, Gujarat, Himachal Pradesh, Karnataka, Maharashtra, Rajasthan, Madhya Pradesh and Tamil Nadu), transmission system strengthening, both Intra State and Inter State, along with setting up of Renewable Energy Management Centre (REMC) and the control infrastructure is being implemented under GECs.
