renewable energy-rich states and another USD3.4 billion of phased interstate investments need to be undertaken to enable power flows across states over long distances. Green Energy Corridors-I Under the Green Energy Corridors (GEC)-I project, a total of 17,000 circuit km and 34,600 MVA of substation capacity is envisaged. Of this, 13,600 circuit km and 16,650 MVA of transformer capacity will be at the intrastate level and 3,400 circuit km and 18,000 MVA of transformer capacity will be at the interstate level. The entire interstate transmission portion under GEC-I will be set up by POWERGRID. The intrastate transmission system, to be set up by the respective state transmission utilities, involves strengthening schemes primarily comprising pooling stations at 132 kV, 220 kV, and 400 kV levels and associated transmission lines. As part of the interstate transmission system, a high-capacity transmission corridor connecting the major renewable-energy pockets from Bhuj in Gujarat (Western Region) to Moga in Punjab (Northern Region) via Chittorgarh/Ajmer/ Suratgarh in Rajasthan (Northern Region) and Tirunelveli and its interconnection in Tamil Nadu (Southern Region) is proposed to strengthen the existing interstate transmission network. The plan also entails setting up pooling stations at Bhuj, Banasakantha, Chittorgarh, Ajmer, Bikaner, and Tirunelveli, as well as other control infrastructure and facilities for the forecasting of renewable generation, balancing infrastructure, dynamic compensation, Renewable Energy Management Centres, and real-time monitoring under the project. In 2013, Germany’s KfW Bank committed to extending a loan of up to EUR1 billion for financing the GEC. KfW’s funds will be made available in three tranches of EUR250 million, EUR500 million, and EUR250 million, respectively. So far, EUR825 million has already been committed by the KfW Bank for the implementation of interstate and intrastate transmission schemes under the GEC-I project. Around EUR750 million will be mainly utilised for the creation of the Bhuj”Chittorgarh/ Ajmer/Suratgarh”Moga high- capacity corridor and for the establishment of the Tirunelveli pooling substation and its interconnection in Tamil Nadu. Another EUR125 million will be allocated for the creation of intrastate networks in the states of Himachal Pradesh and Andhra Pradesh. Work on most of the KfW-funded interstate transmission components is underway, with completion slated for 2016–17. More recently, in December 2015, the Asian Development Bank (ADB) also approved a USD500 million loan to implement several components of the GEC-I project. The ADB aid will be used for the expansion of the GEC in the Northern Region, mainly in the states of Rajasthan and Punjab. ADB-funded components are slated for completion by 2020. Green Energy Corridors-II In addition to the GEC-I project, the GEC-II project is planned by POWERGRID for grid integration of renewables by 2021– 22. In the first phase of the programme, transmission schemes for the ultra-mega solar power parks of about 22,000 MW capacity scheduled to come up during the Thirteenth Plan (2017–22) period will be developed. These solar parks are part

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
