ABOUT THE FORMATS Formats for use in recording and reporting of data in substation operation are being standardized for uniform use at all substations. These formats have been categorized in three ways, formats for log sheets, formats for monthly registers and formats for loose forms. Code Scheme ABCDEF
A Code for Region BC Code for Substation D Code for type of Format/Section in Monthly System Operation Report EF Code for Form Number for a specific type of format/standard Format
Number in the specific section of System Operation Report.
Codes for Regions (A) Northern Region – I - 1 Western Region - I - 2 Southern Region – I - 3 Eastern Region - I - 4 North Eastern Region - 5 Northern Region – II - 6 Southern Region-II - 7 Eastern Region – II - 8 Western Region – II - 9 Codes for substations in Northern Region – I (BC) Kanpur 01 Auraiya 19 Rae Bareilly 43 Agra 02 V’chal BtB HVDC 20 Maharanibagh 44 Ballabgarh 03 Dausa 24 Sitargunj 45 Jaipur/Bassi 04 Bawana 26 Kota 46 Mandola 05 Panipat 27 Pithoragarh 47 Anpara 06 RAPP B 28 Kankaroli 48 Lucknow(UPPCL) 07 Chittorgarh 29 Mainpuri 71 Muradabad 08 Unchahar 30 Tehri Pooling Point 72 Muradnagar 09 Faridabad GPP 31 Gurgaon 73 Panki 10 Samayapur(BBMB) 32 Sikar 74 Sikandara 11 Palla 33 Neemrana 75 Heerapura 12 Meerut 34 Kotputli 76 Bhilwara 13 Allahabad 35 Manesar 77 Bareilly (UPPCL) 14 Bhiwadi 37 Roorkee 78 Singrauli STPP 15 Lucknow 39 Bhinmal 79 Rihand STPP 16 Gorakhpur 40 Koteshwar 80 Dadri HVDC 17 Ballia 41 Merta (RRVPNL) 81 Anta 18 Bareilly 42

Codes for various Formats (D) Log sheets - 1 Monthly Registers - 2 Loose Formats - 3 Sample formats for the above are enclosed in this report For e.g. the Daily Log-sheet for EHV Transformers for Mandola S/S of NR-I shall carry a Form No of 105102. Similarly the register for Monthly Record of Energy meter readings at Bangalore S/S of Southern Region-II shall carry a Form No of 704201. Similarly, outage details in North-Eastern Region shall carry a Form No. of 500305. Sample Formats are enclosed in this report. Note: 1. For Automated/ Remote Operated Substations and wherever automatic data logging function
have been put in place, regions to ensure that operation datas are logged as per the standard formats only.
2. If new Sub-Stations are added in any Region, Regions to assign the next serial number and the same to be intimated to ISO Co-ordinator of CC/OS for records.
3. ER-II & WR-II have been assigned codes for Region (A) as 8&9 respectively. Sub-Station Numbers (BC) for the existing Sub-Stations to be retained and left out numbers to be assigned to new additions of Sub-Stations. The same procedure is to be followed by ER-I & WR-I also for the Sub-Stations which are transferred to ER-II & WR-II respectively.
