COD Ant COD/ Act COD Constraints/ Remarks The scheme was originally designed for import of 4000 MW and put up before SCPSPSR-36 for approval. However, to cater to the huge import requirement of power, the Committee suggested that studies for 6000 MW capacity and additional strengthening be carried out and put up for discussion in the next Standing Committee (37 th ) meeting. Accordingly the scheme has been modified and discussed in SCPSPSR-37, when KSEB requested to construct this link as a multi-terminal HVDC with one Inverter station of 4000 MW at Pugalur and another Inverter station of 2000 MW capacity at Madakathara in Kerala by extending the same HVDC up to Madakathara to enable it to import power from outside. It was decided that the same would be explored and finalized in the next meeting of SCPSPSR. Agenda Notes for the 25 th Meeting of TCC & 26 th Meeting of SRPC 8 of 40

The matter regarding proposed HVDC link between Raigarh-Pugalur was discussed in the 25 th Meeting of SRPC. After discussions it was felt prudent to recommend to Ministry of Power that this proposed link be developed by Power Grid Corporation at the earliest. Only Power Grid Corporation had the desired technical and financial expertise to take up the project in a timely manner. Accordingly, Chairperson, SRPC vide letter dated 25 th September 2014 (Annexure-II) had taken up the matter with Secretary (Power), Government of India. 3.3.4 Angul - Srikakulam PS 765 kv D/C line Transmission Element Implementin g Agency Line length (ckm)/ MVA Capacity Sch.

In addition, Karnataka have to Agenda Notes for the 25 th Meeting of TCC & 26 th Meeting of SRPC 11 of 40

cater their Yerandahalli load of 80 MW from Somanahalli itself. It has also been stated that though SPS on 400 kv Hosur-Salem D/C line has been provided by Tamil Nadu, the ATC has not been increased. Further, due to drawal of KSEB, the flow on 400 kv Kolar-Hosur D/C line is always maintained high. 3.4.3 RoW of 400 kv Mysore-Kozhikode D/C line In the 25 th Meeting of SRPC the following had been noted: KSEB had stated that the completion of 400 kv Mysore-Kozhikode (Areakode) D/C line is urgently required since Northern Kerala was facing acute power shortage. Due to forest clearance and RoW disputes, the line work was held up in Karnataka. 400 kv line works in Kerala and construction of 400 kv substation at Areakode had been completed and kept idle for want of this line. KPTCL had informed that Karnataka State Government had constituted an Expert Committee to examine alternative possibilities for this line. The Committee had almost finalized the Report which was expected to be submitted shortly. In the 101 st OCC Meeting on 11 th November 2014, SR-II, PGCIL had informed that the works on this line had resumed. The status may please be appraised by POWERGRID. Petition No. 120/MP/2014 was heard by Hon ble CERC on 13 th November 2014.

3.5.2 400 kv Edamon-Kochi line In the 25 th Meeting of SRPC, the following had been noted: POWERGRID had filed a petition before Hon ble CERC seeking provisional tariff on the expenditure incurred on construction of Edamon -Cochin 400 kv D/C (Quad) line till 31.03.2014 and adjudication of dispute between the petitioner and Govt. of Kerala with regard to the compensation determined by the latter in terms of Section 67 (4) of the Electricity Act. Hon ble CERC had issued RoP in respect of Petition No. MP/083/2014 (date of hearing 17th June 2014) wherein the following was stated: (d) Under the circumstances, the petitioner finds no way to complete the Projects and seeks recovery of expenditure already incurred in a suitable manner. KSEB had informed that it had been decided that additional compensation of about Rs. 341 Crores would be borne by the Government of Kerala. They were in discussion with PGCIL to work out the schedule and works were likely to commence by mid August 2014. In the 101 st OCCM, KSEB had informed that they are extending all support for the early completion of Tirunelveli- Kochi line in Edamon Kochi portion. KSEB had already taken up the task of liaisoning and a dedicated senior Executive Engineer has been assigned the task. Petition No. 83/MP/2014 was heard by Hon ble CERC on 13 th November 2014. The Commission has reserved order in the Petition. 3.5.3 400 kv Trichur-Kozhikode line (Madakkathara- Areakode) The following had been noted till 25 th Meeting of SRPC: KSEB had stated that this line had already been approved as Regional System Strengthening Scheme. North Kerala would benefit since 400 kv supply could be availed either from Udumalpet or from Mysore for all the 400 kv substations in Kerala. Multi circuit & multi-level circuit was their requirement for surrender of corridor. PGCIL had sought utilization of existing 220 kv Madakkathara- Malaparamba-Areakode S/C feeder. There was no possibility of surrender of RoW of KSEB line presently since energy security of Malabar region was involved. Line works could be taken up only after commissioning of the 400 kv Mysore-Kozhikode line. PGCIL had been requested to initiate the process so that construction could commence immediately after 400 kv Mysore-Kozhikode line was commissioned.

3.6 Transmission Constraints Requiring attention Following constraints have been noted in various fora: Overloading of Hiriyur- Nelamangala D/C & Jindal BTPS S/C Line Till parallel lines are developed KPTCL to restrict upstream generation and downstream load. Prioritizing and expediting commissioning of the transmission system planned for Yermaras TPS. Early Commissioning of 220 kv Hiriyur Gowribidanur D/C line under construction by KPTCL would help in relieving this line to some extent. Hinduja Evacuation Till the ATS is developed total injection at Vemagiri to be restricted to 600 MW. Overloading of 230 kv and below system in TN during high wind season also leading to low voltages Identified evacuation lines to be developed by TANTRANSCO to be prioritized and expedited.

Dynamic Compensation (Approved in 36 th SC) Entity PGCIL Bus Name SC MVA GVA / KA Hyderabad 18.4/ 26.5 Udumalpet 19.4/ 28.0 Trichy 12.5/ 18.0 Dynamic Compensation (STATCOM) Mechanically Switched Compensation (MVAR) Reactor Capacitor + 200 MVAR 2x125 1x125 + 200 MVAR 2x125 1x125 + 200 MVAR 2x125 1x125 Remarks 2015-16 Construction of 400 kv Vijayawada-Nellore Ckt-III & IV lines under system strengthening was underway. Along with this, 2 reactors of 63 MVAR at Nellore and 2 reactors of 50 MVAR at Vijayawada are envisaged for both the lines. The reactors were ready for commissioning at both the ends. During discussions in the OCC forum it was proposed to utilize above reactors at both the stations even before the lines are commissioned. SRLDC had opined that utilization of these reactors would help in containing the high voltage and thus help system operation. In this regard, letter dated 18 th September 2014 (Annexure -VII) had been addressed to the SRPC Members. 11. STUDY GROUP OF SLDCs TO ASSESS TTC/ATC AND OPERATIONAL PLANNING 11.1 Need for having quality node wise data from constituents for optimal utilization of transmission assets has been felt in various forums. Having a dedicated study group in SLDCs for TTC/ATC/Operational Planning would help in addressing this issue to a large extent. Procedure for Relieving Congestion In Real Time Operation mandates SLDC to assess the TTC/TRM/ATC on its inter-state transmission corridor considering meshed intra-state corridor for exchange (import/export) of power with ISTS. In addition, SLDCs are also to designate Main and Alternate Officers as Reliability Coordinator(s). The need for having dedicated system group in each utility and Load Despatch Centres for operation planning had also been discussed in MoP Meeting held on 11 th March 2014 to discuss Task Force Report on Power System Analysis Under Contingency. Agenda Notes for the 25 th Meeting of TCC & 26 th Meeting of SRPC 24 of 40

11.2 A Meeting of the Study Group of the SLDCs was held on 20 th October 2014 (Minutes available at www.srpc.kar.nic.in/website/2014/meetings/special/rnsldc 20-10-14.pdf). Manpower crunch had been highlighted by most of the SLDCs to handle these additional responsibilities effectively. AP & Telangana SLDCs were yet to form a Study Group at the SLDCs. Subsequently a workshop was also organized by SRLDC on 20 th November 2014. 11.3 Considering lower temperature limit (less than 45⁰C) for ATC computation (Kolar-Hosur D/C line) was under examination of NRCE. 12. SEMs ON ALL FEEDERS FOR SECTIONAL LOSSES SRLDC had put this issue to Commercial sub- Committee of SRPC as follows: As per CEA (Installation and operation of meters) Regulations, 2006 and Amendment thereof, 7.1 At one end of the line between the sub-stations of the same licensee, and at both ends of the line between sub-stations of two different licensees. But in the backdrop of increased complexities in Transmission network, a need is felt for installing the SEMs on both ends of all the feeders same licensees also irrespective of ownership. This will help in computing Sectional Loss at each bus and identify the metering deficiencies and under-recordings. Commercial Committee may please approve the proposal so that CTU can do the needful. This issue had been discussed in the 25 th Meeting of Commercial Sub- Committee of SRPC. After deliberations, Commercial Sub- Committee had agreed in principle, but observed that installation of SEMs on all feeders involved considerable cost implications etc. Hence it was agreed that the details of SEMs requirement etc would be furnished by SRLDC so that the matter could be put up to TCC/SRPC for consideration. 13. IEGC RELATED ISSUES REQUIRING ATTENTION/ACTION 13.1 Automatic Demand Management Schemes Automatic Demand Management Scheme in line with clause 5.4.2 (d) of the IEGC was to be provided by all the constituents by 1 st January 2011.SRLDC & SRPC Secretariat had pointed out that automated scheme was to be in place to meet Regulatory requirements. Agenda Notes for the 25 th Meeting of TCC & 26 th Meeting of SRPC 25 of 40

The following is the status update on the action finalized in the 25 th Meeting of SRPC: In compliance of Order dated 22 nd February 2014 of CERC in respect of Petition No. 120/2011, it was learnt that TANTRANSCO had finalized the scheme and communicated to P&C Wing for implementation. Since considerable time had lapsed, the scheme needed to be in place at the earliest. Other Constituents (other than KSEB) also needed to put the ADMS in place. Scheme in TN yet to be implemented. In 101 st OCCM TN had informed that the scheme would be completed by December 2014. The logic would take care of sudden withdrawal of wind generation also. KPTCL had informed that 350 MW loads had been identified for ADMS. Initially the loads would be tripped manually, but within a period of three months, the same would be automated. Scheme in Karnataka yet to be implemented. In the 101 st OCCM Karnataka SLDC had informed that the scheme would be completed by December 2014. AP & Telangana had informed that the new upgraded SCADA system was likely to be in place by October 2014 and ADMS would be subsequently implemented. Scheme in AP & Telangana yet to be implemented. In the 101 st OCCM AP &TS SLDCs had informed that the scheme would be completed by March 2015. KSEB had informed that the scheme (320 MW) had already been implemented. New Scheme which would replace the old implemented scheme at 11 kv was being implemented. 13.2 Inadequate UFRs and df/dt reliefs 13.2.1 Issue regarding inadequate relief through UFRs and df/dt relays had consistently been raised by SRLDC & SRPC Secretariat. SRLDC had also reported the issue under clause 1.5 of IEGC on a number of occasions. SRPC Secretariat had taken up the matter with Constituents for necessary compliance. On 19 th December 2013, Hon ble CERC had issued its Order in respect of Petition No 263/MP/2012. It had directed that SR constituents identify additional feeders and install UFR and df/dt relays to ensure relief as decided by SRPC from time to time. SLDCs had also been directed to map the relays on the SCADA system within three months of issuance of the Orders. Agenda Notes for the 25 th Meeting of TCC & 26 th Meeting of SRPC 26 of 40

13.2.2 Visible relief of the states is as follows : AUFR, df/dt feeders Percentage relief realization w.r.t. SCADA monitored October 2014 August 2014 MAX MIN AVG MAX MIN AVG AP 58% 15% 40% 109% 50% 82% TS 123% 39% 77% KAR 75% 16% 55% 83% 7% 59% KER 106% 52% 74% 80% 23% 48% TN 69% 21% 53% 74% 47% 60% SR 87% 49% 70% 80% 47% 65% Except Kerala and Puducherry all the other constituents were yet to implement the additional feeders All the constituents were yet to complete 100% SCADA mapping. KSEB had approached CERC for time extension for complete the activity. 13.2.3 In the 24 th TCC Meeting after deliberations SLDCs had been requested to examine the matter in consultation with the Discoms. Endeavour to improve the relief figures by about 20 % (at least up to 70 % ) would be ensured by the next SRPC Meeting. The issue is being regularly monitored in the OCCM but there was no significant improvement from the earlier visible relief. 13.3 Low Voltage and installation of UV Relay Following is the status on the actionable points as discussed in the 24 th TCC Meeting: KSEB had finalized the scheme which had been put to higher management and approval was awaited. Scheme was yet to be approved and implemented SRLDC had said that this issue was being followed up since last couple of years and they may be constrained to go for physical regulation measures in low voltage areas. Scheme had been finalized and implemented KPTCL had agreed to implement UV relay scheme. In addition steps would also be taken to provide capacitor of adequate capacity at low voltage nodes. Scheme was yet to be approved and implemented TANTRANSCO had stated that they would maintain the voltage levels within limits at 230 kv level and below. It had been pointed out that loss of wind generation had taken place due to low voltage Agenda Notes for the 25 th Meeting of TCC & 26 th Meeting of SRPC 27 of 40

scenario. States were to maintain voltages within IEGC range and in case voltages are not maintained, then UVR is to be provided as per IEGC. IEGC/CEA Regulations mandate providing UV relays if need arises. 13.4 Restricted Governor Mode of Operation (RGMO)/FGMO of Generating Units & MVAR Interchange In the 25 th Meeting of SRPC, the following had been noted: All GENCOs would endeavor to ensure RGMO response as mandated in the Regulations. Response would be analyzed further in a Special Meeting of Generators to be held during August 2014. Regarding MVAR, the constituents had been requested to kindly comply the decisions taken in various Meetings in this regard. A Meeting in this regard was held on 27.08.2014 (Minutes available at http://www.srpc.kar.nic.in/website/2014/meetings/special/ Minutes_RGMO.27.08.2014.pdf) The response was minimal by most of the generators and there was considerable scope of improvement. Actionable points in respect of RGMO and MVAR finalized in the Special Meeting needed to be implemented. All the SLDCs to monitor the response of the generators in their control area and take up the matter with respective SERC in case of lack of response or inadequate response. (ROP dated 06.07.2014 on Petition No.302/MP/2013) 13.5 Low Voltage Ride Through (LVRT) 13.5.1 The following had been noted in the SRPC/TCC Meeting: There had been 3-4 incidences of wind generation withdrawal of around 1,000 MW in the past one year. This was on account of nonavailability of LVRT feature which was a matter of great concern to grid security. Special Meeting of Protection Sub-Group had been held in this regard on 08 th July 2014 TANTRANSCO had informed that the matter regarding provision of LVRT features was being taken up with the wind developers. Data/information could be jointly studied to assess the root cause for such incidents, whether it could be attributed to variability or on account of non-availability of LVRT/FRT features KPTCL had informed that they were viewing the issue with concern since about 70% of the wind mills in Karnataka Grid may not be equipped with LVRT feature presently. They would take up the issue with wind developers. Compliance in this regard could be planned only in a phased manner. Most of the wind mills (about 95 %) were privately owned and commissioned over a period of 6 to 8 years. Agenda Notes for the 25 th Meeting of TCC & 26 th Meeting of SRPC 28 of 40
