4 400kV S/c line at Tanda and Tanda-Gonda-Shahjahanpur (POWERGRID) 400kV D/c. The present proposal is for evacuation of MW of power to other beneficiaries through ISTS. The nearest POWERGRID Substation to Tanda is Sohawal. Sohawal is an intermediate substation and would be connected to Balia and Lucknow by 400kV D/c. Major transmission system for evacuation of power would be available beyond Lucknow. Accordingly, for evacuation of power from Tanda (2x660MW), following system is proposed: Tanda-Sohawal 400kV D/c Sohawal- Luknow (POWERGRID) 400kV D/c. iv) Proposal / Issues: Long term Access for MW of Tanda (1320 MW) generation of M/s NTPC Limited is proposed, subject to following: Signing the requisite TSA / TSA for Northern Regional Transmission system charges from for 25 years. NTPC in the application has stated that LTA may be issued in the name of beneficiaries. POWERGRID had requested NTPC for the quantum of power name of beneficiaries for signing of LTA with them. Subsequently, the issue was also discussed with NTPC wherein NTPC had informed that allocation of power by Ministry of Power is done at the time of commissioning of generation project and beneficiaries cannot be intimated at this stage. Keeping this in view, LTA be issued in the name of NTPC which may be transferred in the name of beneficiaries after finalization of allocation from Ministry of Power. All the rules pertaining to LTA and connectivity shall be followed by NTPC till the time LTA is issued in the name of beneficiaries. All conditions as listed in Annexure-A. 2.0 : Connectivity and LTA of 500 MW Unchahar Power Project of M/s. NTPC Limited in Uttar Pradesh NTPC Limited had applied for Connectivity and Long Term Access for MW from their 1X500 MW Feroze Gandhi Unchahar TPP (FGUTPP-IV) in District Raebareli, Uttar Page 4 of 27

5 Pradesh. It was discussed that while evolving transmission system for Unchahar-III, there were overloading in 220KV due to which Unchahar - Raebareilly third circuit was planned. Hence, Unchahar new generation cannot be connected to existing generation by 400/220kV transformers as connection of new generation to existing generation may lead to additional injection of power into 220kV system and may overload the system under certain conditions. Accordingly, Connectivity and Long Term Access was granted through Unchahar-Fatehpur 400kV D/c line. Subsequently, M/s NTPC Ltd. vide letter 24/4/2012, have indicated that connectivity of 400kV and 220kV would facilitate operational flexibility in evacuation of power between the stages under various contingencies and also enable timely drawl startup /commissioning of power for the upcoming Stage-IV. The subject 400/220kV ICT feeder can be opened in case of any issue of existing 220kV system over loading under some network configurations. M/s NTPC has proposed 1x315/500MVA transformer for connecting Stage-IV 400kV with existing 220kV. A 400/220kV transformer would provide anchoring to the generating units. Further, connection of 400kV and 220kV would provide operational flexibility. It is proposed that ICT for connecting of 400kV and 220kV may be taken up. Based on system conditions, the transformer may have to be kept open. Members may discuss and approve. 3.0 Long term Access grant to 120 MW Miyar HEP of M/s Miyar Hydro Electric Power Company Ltd.

As per the application, the connectivity for the project is required by April The issue of providing connectivity was discussed during the LTA/connectivity meeting held on 19/12/2011, wherein it was proposed to LILO Dadri Greater Noida 400 kv circuit at Greater Noida (New) along with the establishment of a new 2x500 MVA, 400/220 kv substation at Greater Noida for providing connectivity. However, it was decided that observations / concurrence of UPPTCL would be taken. UPPTCL vide their letter dated 02/02/2012 had communicated their concurrence subject to identification of strengthening & supply to their Greater Noida is not affected. Subsequently it has been informed by Noida Power Company that they have executed a Long Term PPA with M/s Essar Power (Jharkhand) Ltd for procurement of 240 MW power from April 2014 for 25 years. Here it is to mention that CTU has already granted Long Term Access of 400 MW (for Target Beneficiaries) in Northern Region to M/s Essar Power (Jharkhand) Ltd and they have already requested to approve / provide LTA of 240 MW to NPCL, now being the actual beneficiary, out of total approved 400 MW LTA in NR. Presently 400/220 kv, 3x315MVA transformers are installed at Greater Page 19 of 27

20 Noida and the transformers are loaded heavily. Keeping above in view, the matter has been reviewed by CEA and CTU. As the Dadri Ballabgarh 400 kv D/c line has already been Looped in Looped out at three major substations of NCR with high loads i.e. Maharani Bagh, Greater Noida and Nawada, establishment of one additional substation on the same line at Greater Noida would not be appropriate as it would result into over loading of the lines. Therefore, for supply to Noida Power Company Ltd, it would be ideal to have a separate 400 kv line from Dadri/Ballbgarh to meet their requirement. However due to ROW constraint for constructing line from Dadri, it is proposed to provide connectivity from Ballabhgarh 400/220 kv substation. Considering the concentration of growing loads in NCR area, it is proposed to establish a new 2x500MVA, 400/220kV substation at Greater Noida (New) along with Ballabhgarh Greater Noida 400 kv D/c line. From in addition to NPCL, UPPTCL may also draw 220 kv lines to meet their loads from this new substation. Accordingly following is proposed: Ballabhgarh Greater Noida (New) 400 kv D/c Establishment of 2x500 MVA, 400/220 kv GIS substation at Greater Noida (New) with a short circuit current rating of 50 ka. In case of severe ROW constraints, Pole type towers may be used. Members may discuss and concur : Long Term Access to Singrauli Hydro (2x4 MW) Power Project of M/s NTPC Limited in Uttar Pradesh. In accordance with CERC regulations 2009, for Grant of Connectivity, Long-Term Access and Medium-term Open Access in Inter-State Transmission, NTPC Limited has applied for LTA for 8 MW for their hydro project Singrauli, in Uttar Pradesh. LTA for the project is required from for 25 Years. The beneficiaries along with quantum allocated are: UPPCL (4.1MW), Delhi Discoms (2.1MW), Rajasthan Discoms (1.8MW). A copy of the application is enclosed at Annexure-6. As per the application Connectivity with the grid is through NTPC Singrauli Switchyard. In this regard it may be mentioned the application is only for LTA and not for grid connectivity. It is to mention that the generation is not a grid connected entity and Page 20 of 27

21 same is not yet regularized. Before grant of LTA, NTPC need to regularize its connectivity. However as per CERC regulations, hydro generation having a capacity of 8MW cannot apply for connectivity to ISTS. Keeping this in view it is proposed that (i) (ii) LTA can be granted subject to connectivity issue. NTPC may approach CERC to resolve the connectivity issue. Members may discuss and concur. Similarly, NTPC is putting up Solar power projects of 15 MW capacity at Anta and 5 MW at Dadri. The issues for connectivity of these projects need to be deliberated. Here it is to mention that there is no application for connectivity or LTA from NTPC : Long Term Open Access to Rosa Power Company M/s Rosa Power Supply Power Company limited (RSPCL) had applied for LTOA for transfer of 300MW of power from Stage-II (2x300MW) of Rosa Power Project located at Shahjahanpur, U.P.

The LTOA application was discussed and agreed in the Long term Open Access meeting held on 30/05/2009 alongwith 27 th Standing Committee Meeting of Northern region. Power from the generation project is to be injected at Shahjahanpur 400/220 kv substation of POWERGRID. Accordingly, LTOA intimation was issued and BPTA was signed on 23/11/2009. RSPCL now has intimated that they have finalized the long term sale of power from Rosa TPP Phase-II to UPPCL and also signed PPA with them. A copy of the letter from RSPCL is enclosed. In view of this M/s RSPCL has requested for the modifications as follows: o Name of beneficiary - Uttar Pradesh o Location - Interface points between ISTS and UPPCL grid in Uttar Pradesh o Region - Northern region o Capacity MW Page 21 of 27

22 In view of above it is proposed the beneficiary may be modified as Uttar Pradesh instead of Delhi and Haryana, as requested by RSPCL. The total quantum of LTOA shall remain the same. Further, it is to mention that the Long Term Open Access was granted subject to commissioning of Lucknow-Bareilly-Meerut 765kV one circuit and Bareilly-Kashipur- Roorkee-Saharanpur 400kV D/c (Quad conductor), as the power was to be transferred outside the state, to Delhi and Haryana. However as per the present scenario, power is to be delivered within Uttar Pradesh, it is therefore proposed that Long term Access would be subject to commissioning of Bareilly Roorkee 400kV D/c (Quad conductor) and commissioning of Shahjahanpur substation. Uttar Pradesh may indicate whether the transmission charges may be billed directly to them. After agreement by the constituents on the above issue, revised LTA intimation shall be issued.
