However, no concrete status is received yet from NR states. Members may like to discuss the status in different states and ways of expediting the same. 21. Mapping of UFR & df/dt in SCADA systems of state (Agenda by NRLDC) The hon’ble Central Electricity Regulatory Commission (CERC), through its order dated 23rd December 2013 in petition no 221/MP/2012 has ordered as follows: 23 “(c) UFRs and df/dt relays are also be mapped on the SCADA system of each state so that they can be monitored from SLDC/NRLDC. (d) All STUs and SLDCs to map/network the UFR and df/dt on their SCADA system.” The issue is being discussed in various OCC meeting since then wherein it has also been decided that both digital and analog values, of the feeders where such relays have been installed, shall be monitored. In 119th OCC meeting, some of the members stated that there shall be uniform formats for all the states for visualising the feeders. In 120th OCC meeting, the revised uniform format was included. It was also decided to add one more column for the transformer load in the format. These formats have to be compiled by respective state/SLDC by co-ordinating with respective SCADA team of SLDCs. The address of these state pages shall be informed to NRLDC for consolidated view at NRLDC. Furthermore, these templates shall be regularly monitored regarding data availability and other issues for fine tuning. Member may please discuss and take action accordingly. 22. Multiple outages of 400kV Ballabhgarh-Nawada-Greater Noida-Dadri line section : (Agenda by NRLDC) The 400kV Gr.

SPS operations: (Agenda by NRLDC) SPS of 765kV Agra-Gwalior operated on 09th Jun’16 due to sudden import reduction of more than 1500MW. The load relief is summarised below: Load Relief State Haryana Planned As reported SCADA wise relief 265 0% 53% 30 feeder Punjab 361 15% 0% Rajasthan 319 70% 40% UP 200 128% 115% NR 1145 47% 43% The following are the observations regarding the recent SPS operations: • It was observed from the SCADA data that the 132kV Modipuram-Medical college flow increased on tripping of other designated feeders from Modipuram on SPS. Uttar Pradesh may kindly explain for this increase in power flow. • Negative power flow of -1 MW is reported for 132kV GSS Merta-Merta road circuit. Rajasthan may kindly review the radial nature of the feeder. • As per the information submitted for above event, Feeders at Jamsher (Punjab), Kota (Rajasthan), Nara (UP) and 132kV Alwar-Pinan didn’t trip. Major alarm problem reported at Nara (UP). Utilities may provide details for non-operation of SPS. Punjab/Haryana/BBMB may kindly submit the complete feeder wise load relief detail. In addition to above, critical issue is getting adequate relief and all members may discuss reasons for such low relief from SPS and ways to plug this gap. Moreover, on 9th Jun’16, 400kV Rampur-Nalagarh ckt-2 was under non-auto mode. At 15:44:12.200hrs, R-Y phase fault occurred in 400kV Rampur-Nalagarh ckt-2. This line tripping resulted into Power Flow on second line above 850MW and operation of Case-1 of SPS for Jhakri/Karcham/Rampur complex. In Case-1, one unit each at Rampur, Jhakri and Karcham planned to be tripped. As per PMU plot of Karcham Wangtoo station, slight oscillation observed into the system and die down after 4-5second. PMU plot of frequency, df/dt and phase voltages are: 31 Details received from various entities are tabulated below: Time Description Source 15:44:12.200hrs Maximum dip observed in PMU data R&Y-phase 32 Remarks Time difference Reference time 0ms DR details of 400kV Rampur-Nalagarh Rampur and 15:44:12.300hrs ckt-2 tripped from both end Nalagarh end 100ms 15:44:07.881hrs SPS for Power Jhakri SPS Not Flow>850MW operated details Synch 15:44:13.447 hrs SPS signal Karcham 15:44:13.498 hrs Unit-2 of Karcham tripped received time -4200ms at Karcham Details Time Synch 1147ms Karcham Details Time Synch 1198ms As per details, it seems SPS operation is delayed at 400kV Jhakri end. In an earlier incident also delayed operation of SPS was observed. NJPC/JSW may kindly looked into the matter and take corrective action. 29.

Preamble 1.1. This Procedure is issued in compliance to Regulation 6.3B.6 of the Central Electricity Regulatory Commission (Indian Electricity Grid Code) (Fourth Amendment) Regulations, 2016. 1.2. The Central Electricity Regulatory Commission (Indian Electricity Grid Code) (Fourth Amendment) Regulations, 2016 provide the option to Central Generating Stations (CGS) or Inter State Generating Stations (ISGS) to go for reserve shut down where the scheduled generation falls below technical minimum schedule. In addition to above these regulations have specified provisions for compensating the CGS or ISGS for additional fuel cost towards operating below normative plant availability factor & for multiple start / stop operations. 1.3. All the words and expression used in the Procedure shall have the same meaning assigned to them as defined in the Regulations. 1.4. This procedure will be implemented with effect from the date of approval by the Hon’ble Central Electricity Regulatory Commission or any other date as specified by the Commission. 2. Objective 2.1. The objective of the detailed operating procedure is to lay down the role of different agencies, data requirements, procedure for taking generating units under reserve shut down & methodology for identifying the generating stations or units thereof to be backed down up to technical minimum schedule in specific grid conditions such as low system demand, Regulation of Power Supply, incidence of high renewables etc., based on merit order stacking. 3. Scope 3.1. This procedure shall be applicable to RLDCs, SLDCs, CGS & ISGS whose tariff is either determined or adopted by the Central Commission (CERC). In case of a generating station whose tariff is neither determined nor adopted by the 77 Commission, the concerned generating company shall have to factor the provisions specified in the aforementioned CERC Regulations in their Power Purchase Agreements (PPAs) entered into it for sale of power or in order to claim compensation for operating at the technical minimum schedule. 4. Role of Different Agencies in implementing the Procedure 4.1. CGS/ISGS : Generating Agencies shall upload the following figures ex bus for each 15-minute time block on day ahead basis and for every revision on the day of operation i. Declared Capability (DC) of CGS / ISGS in MW ii. Online Declared Capability (DC) of CGS / ISGS in MW iii. Ramp up /down rate unit wise and station wise 4.2. RLDCs: RLDCs shall upload on their webpage the following figures for each 15minute time block on day ahead basis and for every revision on the day of operation. i. Declared Capability (DC) of generating station in MW ii. On-bar Declared Capability (DC) of generating station in MW iii. Ex bus Technical Minimum schedule of the Plant in MW which shall be calculated as 55% of on bar DC of the generating station. iv. Ramp-up/Ramp down rate unit-wise & station wise v. Ex-bus Entitlement of the beneficiary computed from the on-bar DC in MW vi. Ex-bus Entitlement of the beneficiary computed from 55% of on-bar DC in MW vii. Ex-bus Requisition received from the beneficiaries in MW viii. Cumulative Requisitions of all beneficiaries of the generating station in MW 4.3. SLDCs / Beneficiaries: SLDCs/Beneficiaries shall furnish requisition in the following manner as specified in IEGC. i. SLDCs shall submit the anticipated demand to RLDCs for the next day as per IEGC. ii. SLDCs/Beneficiaries shall furnish requisition to RLDC for the next day (D day) by 15:00 hours of current (D-1) day. SLDCs/Beneficiaries shall submit requisition as per their forecasted requirement. iii. SLDCs/Beneficiaries shall check the ‘injection schedule’ (R0) issued at 1800 hours by RLDCs for compliance to the technical minimum norms. 78 iv. v. vi. 4.4. In case the injection schedule for a generating station is less than its technical minimum, the SLDC(s)/Beneficiary (ies) may raise their requisition up to 55% of entitlement if the original requisition submitted earlier is less than 55%. The above procedure shall be followed by the SLDCs/Beneficiaries RLDCs for all subsequent revisions also. Any compensation computed as per Regulation 6.3B shall be borne by the entity, which has caused the plant to be operated at schedule lower than NPAF but at or above technical minimum schedule based on the compensation mechanism finalized by RPCs. Generating stations: i. The generating station shall coordinate with its beneficiaries for providing requisition for making the injection schedule more than or equal to technical minimum schedule. ii. When the scheduled generation falls below the technical minimum schedule, the generating station shall have the option to go for reserve shut down under intimation to concerned RLDC & beneficiaries. iii. Considering that the minimum economic shutdown hours for units are in the range of 2-8 hours depending on the unit (details at Annex-1), the generating stations need to take a pro-active approach in shut down and restart of units from the view point of merit order. iv. The generating station shall submit the details of duration its operation below normative plant availability factor (NPAF) but above technical minimum schedule to the concerned RLDC/SLDC for verification on monthly basis. v. The generating station shall submit the required data to RPC/RLDC/SLDCs as per regulation 6.3B.3. 5. Conditions under which RLDC may direct the generating stations to operate at a schedule below normative plant availability factor (NPAF) but at or above technical minimum. The RLDC may direct a generating station under its scheduling jurisdiction to operate at a schedule below normative plant availability factor (NPAF) in any of the following conditions. i. Threat to grid security ii. To relieve transmission congestion iii. Sudden Change in weather condition iv. Natural calamities such as earth quake, flood etc .. 79 v. vi. vii. viii. ix. x. Prevailing or anticipated Low Demand conditions Due to less requisition received from the beneficiary states Suo-moto revision of schedules in the interest of better system operation (IEGC-6.5.20) high renewable generation Maintaining adequate reserves Any other anticipated condition that is likely to affect reliable grid operation SLDC shall follow the above procedure in case of CGS having 100% share to the state or any other eligible generator under its control area. 6. Methodology for taking generating station or unit(s) thereof under Reserve Shut down 6.1. 6.2. 6.3. 6.4. 6.5. 6.6. The generating station shall submit its declared capability (DC) to RLDC. The beneficiaries shall furnish their original requisition for the next day (Dday) to RLDC by 15:00 hrs. of the current (D-1) day.. Ex-Power Plant (Ex-PP) dispatch schedule of a generating station in a time block shall be computed by RLDCs by taking algebraic sum of requisitions of all beneficiaries of that generating station & same shall be uploaded on website as revision R0 for next day (D) by 18:00 hours of current day (D-1). If the net EX-PP injection schedule for a generating station is less than 55% of the DC on bar the generating station shall intimate the same to all beneficiaries in the format (A-1) given at Annex-2, with copy to the concerned RLDC. A-1 has to be issued by the generators by 19:00 hrs of D-1. The beneficiaries would then review their requisition & submit a revised requisition by 21:00 hrs to the concerned RLDC. Based on the revised requisitions received up to 21:00 hrs, RLDC shall prepare revised injection schedule for concerned the generating station. If the scheduled generation is less than 55% of DC, the RLDC shall review the anticipated demand pattern based on the demand forecast given by states & grid conditions to decide whether technical minimum schedule is required to be provided to the generating station. i. In case the grid conditions demand so in the interest of better grid operation, RLDC would suo-moto revise the schedule to operate it at or above technical minimum but below NPAF. While doing so, it is possible that some beneficary’s requisition would go up to ensure technical minimum. RLDC shall issue R-1 schedule accordingly and this would be intimated to the concerned generating station, beneficiaries and the RPC in format A-2 given at Annex-3. RLDC may also intimate NLDC for 80 invocation of RRAS regulation (up regulation) in case of eligible stations for keeping the unit(s) on-bar for better grid operation if the grid conditions demand so. Such up regulation in real time can be triggered irrespective of prevailing frequency. (Beneficiaries shall not be allowed to revise the schedule down wards at a generating station where one or more unit(s) are running under technical minimum schedule with suomoto revision by RLDC. 6.7. i. ii. 6.8. ii. If the grid conditions do not demand so, the RLDC shall issue R-1 schedule based on the requisitions received. Under such situation, the generating station shall have the option to go for RSD(Reserve shutdown) with intimation to beneficiaries, SLDCs, RLDC and RPC in format A-3 (given at Annex-4). iii. In case of exigencies, RLDCs/NLDC could schedule power to the generating station through RRAS up instruction so as to ensure that the required units are available on bar and operating at the technical minimum level of 55%. Before taking unit(s) under RSD the generating station whose injection schedule is less than technical minimum schedule, it May offer an opportunity to the beneficiaries to review their requisitions particularly to the beneficiaries who had originally submitted requisition as per full entitlement and would be willing to avail the un-requisitioned power of other beneficiaries of that station. May like to sell the requisitioned power under STOA after taking no objection certificate from the concerned beneficiary/SLDC whose unrequisitioned power is intended to be sold under STOA. Before taking unit(s) under RSD, the generating station shall bifurcate the DC in two parts – (i) DC for unit(s) to remain ON-bar & (ii) DC for unit(s) kept under RSD. The generator shall ensure that the DC for unit(s) kept under RSD shall not be more than MCR less Normative Auxiliary Consumption. The DC for unit(s) kept under RSD shall be frozen until its revival from RSD. The beneficiaries shall continue to bear the capacity charge corresponding to total DC including unit(s) kept under RSD. 81 6.9. The above procedure shall be followed for subsequent schedule revisions also. 6.10. Once a unit is taken out under reserve shut down (RSD), the period for which the unit will remain under RSD shall be 24 hours or less if so specified by the generating station. 6.11. A beneficiary having entitlement in a station more than or equal to the capacity of any unit in the generating station may surrender its entitlement for 24 hours or more in consultation with RLDC. In such situation, the RLDC may facilitate RSD of unit(s) of that station on account of the above beneficiary only. The drawal schedule of the beneficiary from that generating stating shall be restricted accordingly for the specified period as requested. The other beneficiaries shall continue to get their full allocation from the total DC in that station. This arrangement could also be extended for two or more beneficiaries in the same generating station. 6.12. 6.13. 6.14. 6.15. RLDC shall compute & upload entitlements corresponding to DC for unit(s) ON-bar and DC for unit(s) under RSD separately. The injection schedule in such case shall be restricted up to ON-bar DC based on the existing requisitions of beneficiaries. One or more beneficiaries and the generating station may decide for revival for unit (s) under RSD with commitment for technical minimum schedule and mutually agreed ‘minimum run time’ of the unit (s) post revival. RLDC may also advise the generating stations to revive unit (s) under RSD for better system operation(IEGC 6.5.20).. In such cases RLDC shall ensure technical minimum schedule. Compensation shall be admissible towards start-up cost as per the provisions in the IEGC 4th Amendment. Regulation of Power Supply: When injection schedule of a CGS/ISGS falls below technical minimum due to imposition of regulation of power supply under the CERC (Regulation of Power Supply) Regulations 2010 and/or CERC order dated 02.09.2015 in 142/MP/2012 by the CGS/ISGS or a transmission licensee, the generator shall try to schedule the surplus power through STOA or PX before opting for reserve shut down. 7. Review of the Procedure after 6 months 7.1. Based on the experience gained through operation for 6 months the Procedure may be reviewed & modified if felt necessary, in the interest of system operation. 82 8. Removal of Difficulties: 8.1. 8.2. Notwithstanding anything contained in this Procedure, NLDC/RLDCs may take appropriate decisions in the interest of System Operation. Such decisions shall be taken and subsequently intimated to CERC (on monthly basis) and the procedure shall be modified /amended, if necessary. In case of any difficulty in implementation of this procedure, this procedure shall be reviewed or revised by NLDC with the approval from the Commission. *** 83 Assessment of Minimum Economic Shutdown hours for coal fired stations S no 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 Plant Name Installed Capacity Region A B C SIPAT-I SIPAT-II SINGRAULI SINGRAULI RIHAND3 RIHAND2 KSTPS-II KSTPS KSTPS CGPL RIHAND1 TALST2 TSTPP-I SASAN VSTPS-II VSTPS-V VSTPS-IV VSTPS-II VSTPS-I KHSTPP-II VALLURNT NSPCL RSTPS RSTPS KHSTPP-I FSTPP FSTPP I RSTPSU7 NTPL FSTPP-II SIMHST2 NLC2EXP NLCEXP NLCIIST1 NLCIIST2 MOUDA-I UNCHAHAR UNCHAHAR BARH UNCHAHAR DADRT2 JHAJJAR BGTPP DADRIT 1980 1000 2000 2000 1000 1000 500 2100 2100 4150 1000 2000 1000 3960 1000 500 1000 1000 1260 1500 1500 500 2100 2100 840 1600 1600 500 1000 500 1000 500 420 630 840 1000 420 210 1320 420 980 1500 250 840 WR WR NR NR NR NR WR WR WR WR NR SR ER WR WR WR WR WR WR ER SR WR SR SR ER ER ER SR SR ER SR SR SR SR SR WR NR NR ER NR NR NR AR NR Annex-1 Heat Rate Fuel cost for Approx light up cost NAC increase at Oil in kL required increase in % at one(1) hour one Approx oil for cold start up 55% load as per Variable cost at 55% plf for cold start as 55% load as per rate in Rs/MT assuming density of unit operation at per IEGC IEGC IEGC oil as 1.0 55% load Variable Cost Unit capacity Normative Aux Consumption (NAC) paise/kWh MW % % % D E F G H 122 125 126 126 127 129 129 131 131 135 144 146 146 153 153 156 157 162 166 199 203 206 207 207 208 214 214 221 222 228 232 241 253 260 260 260 271 272 276 278 303 307 308 323 660 500 500 200 500 500 500 500 200 800 500 500 500 660 500 500 500 500 210 500 500 250 500 200 210 500 200 500 500 500 500 500 210 210 210 500 210 210 660 210 490 500 250 210 3 6 6 6 6 6 6 6 6 3 6 6 6 3 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 3 6 6 6 6 6 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 5.75 5.75 6.88 6.88 5.75 5.75 5.75 6.68 6.68 5.00 7.75 5.75 5.75 6.00 5.75 5.75 5.75 5.75 9.00 5.75 5.75 8.00 6.68 6.68 9.00 6.47 6.47 5.75 5.25 5.75 5.25 10.00 8.50 10.00 10.00 5.75 9.00 9.00 5.75 9.00 5.25 5.25 8.50 8.50 paise/kWh I = D*(100+G)*(100F)/(100*(100-F-H)) Rs. lakhs kL Rs/MT Rs. lakhs hours J K L M=K*L/100000 N = M/J 127 134 135 135 136 138 138 140 140 141 154 156 156 159 164 167 168 174 178 213 217 221 222 222 223 229 229 237 238 244 249 258 271 279 279 279 290 292 287 298 325 329 330 346 4.13 3.21 3.19 1.28 3.26 3.31 3.31 3.33 1.33 5.58 3.61 3.74 3.74 5.17 3.92 4.00 4.03 4.15 1.73 5.10 5.21 2.58 5.26 2.10 2.16 5.45 2.18 5.67 5.72 5.85 5.98 5.90 2.64 2.67 2.67 6.67 2.82 2.83 9.34 2.89 7.66 7.91 3.83 3.38 110 90 90 50 90 90 90 90 50 130 90 90 90 110 90 90 90 90 50 90 90 50 90 50 50 90 50 90 90 90 90 90 50 50 50 90 50 50 110 50 90 90 50 50 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 20000 22.00 18.00 18.00 10.00 18.00 18.00 18.00 18.00 10.00 26.00 18.00 18.00 18.00 22.00 18.00 18.00 18.00 18.00 10.00 18.00 18.00 10.00 18.00 10.00 10.00 18.00 10.00 18.00 18.00 18.00 18.00 18.00 10.00 10.00 10.00 18.00 10.00 10.00 22.00 10.00 18.00 18.00 10.00 10.00 5.3 5.6 5.6 7.8 5.5 5.4 5.4 5.4 7.5 4.7 5.0 4.8 4.8 4.3 4.6 4.5 4.5 4.3 5.8 3.5 3.5 3.9 3.4 4.8 4.6 3.3 4.6 3.2 3.1 3.1 3.0 3.1 3.8 3.7 3.7 2.7 3.5 3.5 2.4 3.5 2.4 2.3 2.6 3.0 Notes: 1) https://bharatpetroleum.com/Our-Businesses/I&C/Petro-Prices.aspx Source for fuel oil prices 2) For CGPL Mundra, oil taken for cold start up is assumed as 130 kL by extrapolating the figures for 500 MW and 660 MW in the IEGC amendment 3) 4) Minimum economic shutdown hours As per the CEA Technical Standards for construction of electrical plants and electrical lines, Cold start > 72 hours after shutdown when turbine metal temperatures are below 40 % of full load values Hot start <10 hours after shutdown when turbine metal temperatures are approximately 80% of full load values Warm start between 10 and 72 hours when turbine metal temperature is between 40-80% of full load values Fuel Oil requirement falls to 30% for hot start and 50% for warm start approximately as compared to cold start. 84 Format A1: Intimation for Technical Minimum Schedule Date: dd/mm/yyyy From: (Name of Generating Station) / (Name of Owner Organization) To: SLDC/Beneficiary-B1 / B2 / B3 /……….
