Sheshadri Power & Infrastructure 1320 Mahabubnagar Dist., A.P. Sept, 2013 (P) Ltd. 8. Simhapuri Energy Pvt. Ltd Nellore Dist., A.P. 4 th Qtr North Chennai Power Co. Ltd Tiruvallur Dist., T.N. Feb, 2015 Total 10,520 The Connectivity to ISTS for above IPP generation projects is proposed to be granted as explained below. East Godavari Dist., Andhra Pradesh The availability of Natural Gas in Krishna-Godavari river basin has facilitated the establishment of number of IPP Natural Gas based generation projects in Vemagiri area of East Godavari Dist. in Andhra Pradesh. Presently there are 7 numbers of IPP generation projects under operation and meeting the load requirements of the State of Andhra Pradesh. For this APTRANSCO has established a 400/220kV pooling station at Vemagiri & bringing the power from these IPP generation projects. These IPP generation projects are connected to Vemagiri (APTRANSCO) at 400kV level like GVK (Jegurupadu) Phase-II (220MW), Vemagiri Power (370MW), Konaseema (434MW) & GVK Gautami (Samalkot) (464MW). The other three 3 numbers of IPP generation projects are connected through 220kV line & meeting the local load Page-1 of 10

4 requirement of the area, they are GVK (Jegurupadu) Phase-I (217MW), Spectrum Power (208MW) & Reliance Energy (220MW). GVK & Reliance Vemagiri 400kV S/s GVK & RVK Further availability of the Natural Gas as fuel has attracted the IPP developers for expansion of their generation plants with additional units. These IPP developers have applied for Connectivity to Inter-State Transmission System (ISTS) under CERC Regulations, Earlier GMR Energy have already been granted Connectivity to ISTS through GMR switchyard Khammam 400kV quad D/c line as well as granted Long Term Access, however beyond Khammam additional strengthening is to be identified, if required, and GMR Energy & other IPP shall share the transmission charges. Further in addition to GMR Energy, IPP generation developers located in the Vemagiri area as mentioned in the Table above at Sl. No. 1 to 6 have also applied for Connectivity to ISTS. From the Vicinity map it may be seen that these generation projects are located very nearby to each other, even some of them share the boundary walls. Therefore looking into the additional connectivity applications of 6860MW natural gas based generation in the vicinity, it proposed for establishment of 2 nd 400kV pooling station in Vemagiri area through LILO of Gazuwaka Vijayawada 400kV S/c line with the provision of 765kV level upgradation in addition to the existing Vemagiri (APTRANSCO) to pool the power from these IPP generation projects. The pooled power can further be evacuated to supply different load centers Page-2 of 10

5 through 765kV lines which may be planned subsequently once these IPP developers apply for Long Term Access. The charges towards establishment of Vemagiri Pooling Station-II shall be shared by the IPP developer located in East Godavari Dist, Andhra Pradesh. Here it is pertinent to mention that Grant of Connectivity to ISTS as per CERC Regulations, 2009, shall not entitle an applicant to interchange any power transfer with the grid unless it obtains long-term access, medium-term open access or shortterm open access. Looking above into view some of the generation expansion which are connected at 400kV level may be granted connectivity through bus extension of the existing generation switchyard, which later on may be inter-connected to Vemagiri pooling station-ii once they apply for Long Term Access. 1.
