3.14.2. The depreciation to be allowed for the year should be based on the value of the gross fixed assets as stated in clause 40 of MYT Regulation, 2011. The depreciation for the FY 2015-16 has been taken from the Profit & Loss statement as per the APTEL order on appeal nos. 108 of 2013, 149 of 2015, 171 of 2014 and 172 of 2014 dated 21st July 2016. Further, GETCO has adopted treatment of depreciation on Grants and deferred income as per above referred APTEL order.
3.14.3. GETCO receives Government Grants, Subsidies and Consumer Contribution @ 11.75% of the closing balance as income during the year (Deferred income). The depreciation on the assets created out from such deferred income is negated from the depreciation applicable for the FY 2015-16. In line with the above treatment, we have not to consider deferred income on grants/ consumer contributions as other income of FY 2015-16. The total amount received for Government grants/ consumer contributions/ subsidies up to 31st March, 2015 was Rs. 2187.99 Crores and additions during the year were Rs. 147.59 Crores. Depreciation on the assets funded by way of Government grants/ consumer contributions/ subsidies at Depreciation rate of 4.87% comes to Rs. 110.21 Crores.
3.14.4. The variation in the amount of depreciation as per the actual cost incurred by GETCO in FY 2015-16 against the amount approved by the Hon’ble Commission is Rs. 97.28 Crores. This can be considered as gain/ (loss) on account of uncontrollable factor and has been appropriately treated as indicated in below tables.

around 6%. This would only address the inflation aspect of O&M costs but is insufficient to meet additional expenses on account of 7th pay commission.
4.9.4. As per GETCO estimates, additional expense to the tune of Rs 145 Cr in FY 2016-17 would be needed to address the 7th pay commission impact. This estimated year-on-year impact considering an escalation of 5.72% is show below:
TH TABLE 52 : ADDITIONAL IMPACT OF 7 PAY COMMISSION FOR FY 2016-17 TO FY 2020-21 Rs. Crores

4.9.5. As seen from the above table above, the amount is significantly higher (11.2% of projected O&M expenses) and disallowance of the same will have a considerable strain on GETCO finances and may even lead to operational cash flow issues.
4.9.6. Therefore, it is requested to the Hon’ble Commission to approve the additional impact on account of 7th pay commission as show above and allow GETCO for recovery of the same.
4.9.7. It is hereby requested to the Hon’ble Commission to approve the O&M expenses for the control period.
4.10. DEPRECIATION FOR FY 2016-17 TO FY 2020-21 4.10.1. The Gross Fixed Assets & Depreciation for the control period has been computed on basis of accounts of FY 2015-16. Depreciation for the year has been calculated considering the GERC norms for various blocks of assets.
4.10.2. GETCO has computed the net depreciation by negating the depreciation on account of assets funded by Consumer Contribution/Grants as per the APTEL order on appeal nos. 108 of 2013, 149 of 2015, 171 of 2014 and 172 of 2014 dated 21st July 2016.
4.10.3. GETCO receives Government Grants, Subsidies and Consumer Contribution @ 11.75% of the closing balance as income during the year (Deferred income). The depreciation on the assets created out from such deferred income is negated from the depreciation applicable for the FY 2016-17 to FY 2020-21. In line with the above treatment, we have not projected any deferred income on grants/ consumer contributions as other income of FY 2016-17 to FY 2020-21.
4.10.4. Cumulative Consumer Contribution/Grants as 31.03.2016 is Rs. 2335.57 Cr.

Description of Major EHV Substations proposed during 3rd Control Period:
Capital expenditure plan was prepared considering requirement of various 66 KV substations proposed by Distribution Companies, creation of 220 KV and 400 KV substations for power evacuation from generation projects and strengthening of network.
The emphasize is on strengthen the transmission network of GETCO to avoid disturbance in system, as well as to establish transmission network for facilitating evacuation of power from proposed power projects in Gujarat.
1. 765 KV Substations
765/400/220/66 KV Chharodi, Dist: Ahmedabad
Ahmedabad is the largest and fastest developing city in Gujarat. The distribution of power to the Ahmedabad City is under the purview of Torrent Power Ltd. (TPL) and Uttar Gujarat Vij Company Ltd. (UGVCL). In case of UGVCL license area, the consumption of energy is mainly on account of industrial category and railway traction category. Also, huge demand growth is anticipated in the periphery of Ahmedabad city area which is being catered by UGVCL. Therefore, the need is felt for strengthening of Ahmedabad City and peripheral network to cope up with anticipated load growth, to increase reliability and capacity of source in some of the pockets viz. industrial areas and to create alternative source for existing and proposed substations.
Sanand is developed as a major Auto Hub in India. Tata & Ford has already developed their car manufacturing plant at Sanand. It is pertinent to note that this huge investment around
Gujarat Energy Transmission Corporation Limited Page 64 Petition for True Up for FY 2015-16, Multi-Year ARR for FY 2016-17 to 2020-21, Final ARR for FY2016-17 and Tariff for FY2017-18
Sanand will attract lot of small scale industrial development in the area. Therefore, it is necessary to strengthen the EHV transmission network around Sanand area. It is proposed to create a 400/220 KV substation at Chharodi (near Sanand).
Further, POWERGRID has already created 765/400 KV substation at Vadodara along with interconnection to 765 KV Indore (Madhya Pradesh) and 765 KV Dhule (Maharashtra) substation to deliver share of GUVNL from Central Sector projects. 400 KV and 220 KV interconnections for GETCO is already planned for further transmission of power in Gujarat State. Also, POWERGRID is developing 765/400/220 KV substation each at Bhuj and Banaskantha under Green Energy Corridors. GETCO have planned down-stream 400 KV network from both these substations. However, direct 765 KV interconnection is not planned so far to tap power from ISTS network. Further, GSECL is planning to set-up 2 x 800 MW power plant at Dhuvaran to be established during 13th Five Year Plan. Therefore, it is proposed to up-grade 400 KV Chharodi (to be commissioned by 2017-18) to 765 KV level at later stage by year 2020-21. Also, adequate space is available at Chharodi substation and 400/220 KV layout is designed in such a way to upgrade it at 765 KV later stage. Therefore, for evacuation of 1600 MW power from Dhuvaran TPS and also to tap power from ISTS network to a major load centre in the periphery of Ahmedabad city, it is planned to upgrade 400 KV Chharodi substation to 765 KV level by 2020-21.
2. 400 KV Substations
400/220/132 KV Sankhari, Dist: Patan
400 KV Sankhari substation (Patan District) is proposed to strengthen 220 KV network of the area. LILO of 400 KV D/C Vadavi – Zerda line (ISTS line) is proposed at this substation for providing strong source of power from Vadavi & Zerda substations which are connected with Adani & UMPP Mundra power projects. Further, creation of this substation will also facilitate power evacuation from Charanka solar park and other renewable projects in North Gujarat area. Also, it will provide alternative source of power supply to 132 KV Patan & Deesa substations which are fed radially today.
400/220/66 KV Bhachunda, Dist: Mandvi
Power supply in Abdasa and other adjoining villages are being fed through weak 66 KV network of 66 KV Naliya, Netra, Kothara, etc. substations. These substations are being fed through long 66 KV lines (Around 50 Km) from 220 KV Nakhatrana substation. Moreover, big cement industries i.e. M/s. Sanghi Cement, M/s. ABG Cement & M/s. Jay Pee Cement etc., have already invested in the area and are looking for strong 220 KV grid connectivity. Further, huge investment is being envisaged in the area from various industries in the field of Cement, Power, and Raw Salt etc. Therefore, it is proposed to create a 220 KV substation at Bhachunda, Taluka: Abdasa to strengthen existing weak 66 KV network in the area. Further, considering huge renewable potential in the area, it is proposed to have 400/220 KV system at Bhachunda under Green Energy Corridor scheme.
400/220 KV Vav, Dist: Kutch
At present installed capacity of 220 KV Vav substation is 550 MVA (220/66 KV– 5X100 MVA+1X50 MVA) and maximum load is reached up to 467 MVA. Also, 220 KV Vav substation is connected with Sachin, Popda, Kosamba & Mota substations and Kawas, Utran & Kakrapar power stations. Further, on bar availability of generation in the south Gujarat area is reduced substantially due to either costly fuel or non availability of gas. With commissioning of Ukai TPS Unit No. 6, having capacity of 500 MW, power availability is increased at 400 KV level. This has resulted into critical loading of 220 KV S/C Kosamba– Vav & 220 KV D/C Ukai–Mota lines. Therefore, a long term solution is needed to evaluated power and to reduce loading on above lines and also to balance the system with future demand during non availability of gas based generation on bar in the area. Accordingly, it is proposed to upgrade 220 KV Vav substation to 400 KV level.
400/220/66 KV Fedra, Dist: Ahmedabad
Fedra is located near Dholera in Dist. Ahmedabad. Presently demand of the area is being catered through 132 KV and 66 KV network. It is not feasible to have additional outlets from nearby 400 KV Chorania and 220 KV Limbdi substations. Dholera SIR is jointly implemented
Gujarat Energy Transmission Corporation Limited Page 65 Petition for True Up for FY 2015-16, Multi-Year ARR for FY 2016-17 to 2020-21, Final ARR for FY2016-17 and Tariff for FY2017-18
by Government of India and Government of Gujarat under Delhi-Mumbai Industrial Corridor (DMIC). GoG has already enacted the Gujarat Special Investment Region Act 2009 for the development of SIR in the State. Dholera SIR has planned the power requirement distribution system through five pockets. The first Activation Area (AA) of around 22.5 Sq. Km. requires about 380 MW of power tentatively from March-2018 onwards. Existing network in the area is not capable to handle such huge demand growth. Therefore, 400 KV substation at Fedra is proposed.
400/220/66 KV Kalavad, Dist:Jamnagar
The Kalavad area is centrally located between Jamnagar and Rajkot and is agriculture dominated as well as industrially potential zone. The existing 220 KV Jamnagar substation does not have enough space for expansion. The 66 KV lines feeding the heavy inductive load of surrounding substations are quite long resulting in poor voltage profile. The creation of this substation will facilitate improvement in voltage profile and cater the load of up- coming 66 KV substations and a few 66 KV substations fed from 220 KV Jamnagar substation can be diverted on this substation thereby giving a relief on 220 KV Jamnagar substation. Further, considering space constraints and outlet issues from Hadala, it is proposed to have 400 KV system at Kalavad to provide strong source to heavily loaded 220 KV Nyara & Kangasiyali substations. This will also facilitate integration of huge renewable power surrounding Bhatia & Bhogat substations.
400/220/66 KV Bhogat, Dist: Devbhumi Dwarka
Around 400 MW renewable capacity is already installed in the area and about 250-300 MW renewable capacity is planned to be added by 2017-18. Further, the entire area is having seasonal load pattern and it is observed that the local consumption is getting reduced considerable during high wind season. Constraints are already observed in the evacuation of renewable power with the existing installed capacity, during typical grid conditions. Therefore, around 700 MW renewable power from the area cannot be evacuated through existing network in the area. Therefore, 400 KV Bhogat substation is proposed.
400/220/66 KV Achhalia, Dist: Bharuch
At present skewed generation dispatch scenario is observed in real time grid operation. This has resulted into reduced on-bar availability of generation available at 220 KV & 132 KV network. Particularly in South & Central Gujarat area, it is observed that around 5000-6000 MW generation integrated at 220 KV & 132 KV remains idle. Simultaneously, power projects with huge capacities viz. UMPP (4150 MW), Adani (2640 MW), Essar-Vadinar (1200 MW) and increased Central Sector share has resulted into large available power at 400 KV level. This has resulted into critical loading of many 220 KV lines especially in South & Central Gujarat area. Therefore, to tap available power at 400 KV level and to reduce loading on 220 KV network in Central Gujarat area, it is propsed to create 400 KV Achhalia substation.
400/220/66 KV Prantij, Dist: Mehsana
In North Gujarat, 2 Nos. of 400/220 KV substations viz. Soja in Dist. Mehsana and Zerda (Kansari) in Dist. Banaskantha are existing. Also, 400/220 KV Sankhari substation in Dist. Patan is under construction and will be commissioned in by 2016-17. In Dist. Sabarkantha, 3 Nos. of 220 KV substations viz. Dhansura, Agiyol (Himmatnagar) and Mathasur (Bhutiya) and 2 Nos. of 132 KV substations viz. Talod and Idar are existing. UGVCL have demanded to create a 220 KV substation near Prantij in Dist. Sabarkantha considering industrial and agricultural load in the adjoining area. However, looking to the weak 220 KV connectivity for above substations, it is extremely essential to create a 400/220/66 KV substation near Prantij (District: Sabarkantha) to cater the load growth of the surrounding area and to strengthen 220 KV network of the area thereby improving the reliability and stability of the system.
400/220/66 KV Shapar, Dist: Surendranagar
At present, 66 KV Daladi (10 MVA), Than (30 MVA), Tarnetar (20 MVA) and Sara (30 MVA) substations are fed through 66 KV S/C Wankaner – Daladi – Than – Tarnetar - Sara line (Dog). Total line length from Wankaner to Sara is of the order of 48 Km. 66 KV Sara substation is indirectly connected with 220 KV Halvad and Dharangadhra substations
Gujarat Energy Transmission Corporation Limited Page 66 Petition for True Up for FY 2015-16, Multi-Year ARR for FY 2016-17 to 2020-21, Final ARR for FY2016-17 and Tariff for FY2017-18
through 37 Km and 45 Km transmission line respectively. Similarly, 66 KV Chotila (20 MVA), Bamanbora (15 MVA) and Thikariyali (10 MVA) substations are fed radially through 66 KV S/C line from 66 KV Mahika (20 MVA) substation which in turn is connected to 132 KV Wankaner substation. Considering future load growth in the area, PGVCL have already proposed to create a new 66 KV substation at Than-II. Therefore, it is proposed to create 220 KV substation at Shapar in order to provide strong source to 66 KV Than and Sara substations, to reduce loading on 132 KV Wankaner substation, to provide alternative source to Chotila and other substations in the area and to address the load growth in the area. Also, around 20000 MW generation including renewable capacity is anticipated in Saurashtra & Kutch area. Therefore, it necessary to create a transmission network which would facilitate transfer of surplus power from Saurashtra and Kutch to other part of Gujarat OR to CTU network for further transmission to neighboring States. Accordingly, it is proposed to have 400 KV system at Shapar substation.
3. 220 KV substations:
220/132/66 KV Gotri, Dist: Vadodara
Vadodara is the third largest and most populated city in Gujarat state after Ahmedabad & Surat. Major industries including petrochemicals, engineering, pharmaceuticals and plastic are located in Vadodara city. Major prevailing load of Vadodara city is catered through 132 KV Gotri substation and 220 KV Jambuva substation. The main source for 132 KV Gotri substation is from 220 KV Jambuva S/s and 400 KV Asoj S/s, as Gotri is disconnected from Dhuvaran TPS & generation of GIPCL is reduced considerably due to high fuel cost. It becomes more critical to cater the load of Vadodara city & surrounding area. Looking to the present 132 KV & 66 KV transmission network and future load growth surrounding Vadodara city, it becomes necessary to divert load on 220 KV network especially with reduced generation at 132 KV class. Considering availability of space and also very important fact that existing 132 KV D/C Jambuva – Gotri line is originally a 220 KV line with Zebra conductor and can be easily used for 220 KV class, it is proposed to upgrade 132 KV Gotri substation to 220 KV level.
220/66 KV Santej, Dist: Ahmedabad
Installed capacity of 220 KV Chhatral is 300 MVA (220/66 KV, 3X100 MVA) and maximum load is reached upto 230 MVA. 66 KV Santej substation is operating in radial having single source from 220 KV Chhatral substation. Further, 66 KV network surrounding 66 KV Bopal, Bhadaj & Science city is getting loaded critically and it is difficult to handle any outage in the area. Also, tremendous load growth is anticipated in this peripheral area of Ahmedabad city. Therefore, to cater existing demand and also to meet future load growth, it is proposed to upgrade 66 KV Santej substation to 220 KV level which will cater load surrounding 66 KV Santej, Bhadaj, Science city, Shella, etc, substations.
220/132/66 KV Kawant, Dist: Chota Udepur
Kawant & Naswadi taluka are tribal area of Gujarat state. At present, there are 133 Nos. of villages in Kawant taluka, 230 Nos. of villages in Naswadi taluka. There are total 18 Nos. of 66 KV substations and 2 Nos. of 132 KV substations (132 KV Chhota Udepur and 132 KV Tilakwada) under Bodeli (TR) Division. The type of the load in Kawant & Naswadi taluka is Agriculture and most of the feeders in JGY and Agriculture category are having average length around 80 to 90 Kms. Due to more length of these feeders, the losses are very high and consumers could not get quality power supply with grid voltage profile. Further, MGVCL has proposed to create 9 Nos. of 66 KV substation in the area of Kawant, Chhotaudepur, Naswadi to provide better services to the tribal people. Therefore, it is proposed to create 220 KV Kawant substation which will cater demand of 66 KV Kawant, Naswadi, Koshindra, Vandha Chalmali, Zoz, Rangpur and Khanda, etc. substations. Also, by establishing 220/132 KV system at Kawant, it will provide 2nd source of power supply to 132 KV Chhotaudepur and Tilakwada substations.
220/66 KV Rajula, Dist: Amreli
Installed capacity of 220 KV Savarkundla is 300 MVA (220/66 KV, 3X100 MVA) and maximum load is reached upto 230 MVA. Also, installed capacity of 220 KV Otha substation is 150 MVA (220/66 KV, 1X100 + 1X50 MVA) and maximum load is reached upto 125 MVA.
Gujarat Energy Transmission Corporation Limited Page 67 Petition for True Up for FY 2015-16, Multi-Year ARR for FY 2016-17 to 2020-21, Final ARR for FY2016-17 and Tariff for FY2017-18
Further expansion at 220 KV Savarkundala substation is not possible. There is tremendous growth of Agriculture and industrial load surrounding Rajula area which will be reflected on existing 66 KV network. By creation of proposed 220 KV Rajula substation load of 66 KV Rajula, Babariyadhar, Billa, Agariya Mota can be catered from proposed 220 KV Rajula substation.
220 KV Bagodara, Barejadi, Chiloda, Bhat, Dist: Ahmedabad
Ahmedabad is the largest and fastest developing city in Gujarat. The distribution of power to the Ahmedabad City is under the purview of Torrent Power Ltd. (TPL)- around 80% and Uttar Gujarat Vij Company Ltd. (UGVCL)- around 20%. In case of UGVCL licence area, the consumption of energy is mainly on account of industrial category and railway traction category. Also, huge demand growth is anticipated in the periphery of Ahmedabad city area which is being catered by UGVCL. Therefore, the need is felt for strengthening of Ahmedabad City network to cope up with anticipated load growth, to increase reliability and capacity of source in some of the pockets viz. industrial areas and to create alternative source for existing and proposed substations. Therefore, to cater anticipated load growth and for the strengthening of existing network surrounding Ahmedabad City area, it is proposed to have followings;
(1) 220 KV Bagodara substation located on National highway No. 8A, (2) up-gradation of existing 66 KV Barejadi to 220 KV level, (3) up-gradation of existing 132 KV Chiloda to 220 KV level, (4) up-gradation of existing 66 KV Bhat to 220 KV level.
220/66 KV Virpore, Dist: Tapi
Tapi is a Tribal district of Gujarat state. At present there are 13 nos. of 66KV substations (i.e. 66KV Uchchhal, 66KV Naranpura, 66KV Rumkitalav, 66KV Kukarmunda, 66KV Nizar, 66KV Songadh, 66KV Ukai, 66KV Vyara, 66KV Valod, 66KV Dolwan, 66KV Manglia, 66KV Virpore and 66KV Jamkhadi) in Tapi district. By creation of 220 KV Songadh substation, 66 KV Vyara, 66 KV Uchchhal, 66 KV Naranpura, 66 KV Jamkhadi substations may get second strong source.
220/66 KV Amod, Dist: Bharuch
Amod and Jambusar area is being fed through long 66 KV line from 220 KV Gavasad substation. Many industries are already established surrounding Jambusar area and future growth is also anticipated in the area. Presently, the 66 KV network surrounding Amod and Jambusar area are having dog conductor therefore low voltage and interrupted power supply issues are observed. Strengthening of existing structures is quite difficult due to radial connections and old existing structures. Moreover, GIDC is developing Wagra as industrial hub with all infrastructures. In addition, the Amod area is strategic location for industrial development due to availability of waste land and adequate distance from population. Therefore, it is proposed to up-grade existing 66 KV Amod substation to 220 KV level.
220/66 KV Babara, Dist: Amreli
Area surrounding 132 KV Jasdan is having high agriculture demand. 132 KV Jasdan is fed through 132 KV S/C lines from Paliad and Gondal substations. During peak agriculture demand period voltage profile at far end substations is very poor. Also, further expansion of 132 KV Jasdan substation is not possible due to space constraints. Further, huge demand growth is anticipated in the surrounding area fed from Jasdan substation. Therefore, there is a strong need to divert load from 132 KV network to 220 KV level by creating new 220 KV substation in the area. Accordingly, it is proposed to create 220 KV Babara substation which is located around 15 KMs from Jasdan substation.
220/66 KV Sarigam, Dist: Valsad
66 KV Umargaon (50 MVA) substation is being fed from 66 KV Sarigam (40 MVA) substation which in turn being fed from 220 KV Bhilad substation (300 MVA). 66 KV Sarigam substation is also feeding power to 66 KV Sanjan (20 MVA) and Umargam-II (10 MVA) substations in the area. All these substation are heavily loaded substations and it

becomes extremely difficult to cater the load in case of tripping of source lines to these substations. Further, load on 220/66 KV, 3x100 MVA ICTs at Bhilad has already reached up to 258 MVA. Moreover, huge industrial load growth is expected in the area. Also, it is extremely difficult to construct new EHV transmission lines in the area considering severe RoW issues. Therefore, it is proposed to up-grade existing 66 KV Sarigam substation to 220 KV level.
220/66 KV Gariyadhar, Dist: Bhavnagar
Tremendous growth of agriculture connections is anticipated surrounding Gariyadhar area due to high water potential. Critical loading of 66 KV lines along with reduced voltage profile is observed in the surrounding area especially during peak demand of agriculture season. Also, it is not possible to have additional outlets from 220 KV Dhasa & Savarkundla substations. Therefore, to cater future demand growth in the area and also to provide 2nd source of power supply to 66 KV substations, it is proposed to create new 220 KV Gariyadhar substation.
220/132/66 KV Wankaner, Dist: Morbi
At present installed capacity of 132 KV Wankaner substation is 150 MVA (132/66 KV – 3X50 MVA) and maximum load is reached up to 128 MVA. The main source of 132 KV Wankaner substation is 220 KV Lalpar substation through 132 KV S/C Lalpar – Wankaner line (i.e. ACSR Panther conductor, 25 RKM) and maximum load is reached up to 85 MW. At present, to control loading on 132 KV S/C Wankaner – Lalpar line, 132 KV S/C Lalpar – Wankaner and 132 KV S/C Wankaner – Dhrol lines are opened from Wankaner end and connected with each other to have 132 KV S/C Lalpar – Dhrol line. It is proposed to up- grade existing 132 KV Wankaner substation to 220 KV level, which will provide strong source to 132 KV Sitagadh, Dhrol, Jamnagar, Vagashiya & Mota Dahisara substations.
220/132/66 KV Zalod, Dist: Dahod
Dahod is a Tribal district of Gujarat state, having 696 Nos. of villages and 7 Nos. of Talukas, covering 3733 sq. km. of area. At present there are 7 Nos. of 66 KV substations (i.e. 66 KV Devgadh Baria, Limkheda, Zalod, Kharedi, Sarasava, Limbdi and Nalvi substations) being fed from 132 KV Dahod substation to provide power supply to entire Dahod district. The type of the load in Dahod district is mostly Agriculture and most of the 11 KV feeders are having average length more than 100 Km. Due to more length of these feeders, the losses are very high and consumers could not get quality of power supply with good voltage profile. Further, 66 KV line length is also high due to availability of only one EHV source i.e. 132 KV Dahod substation e.g. 66 KV Santrampur substation is being fed from 132 KV Dahod substation through 67 KM long line through 66 KV Limbdi, Zalod and Saraswarpur substations. Therefore, to provide alternative source of supply to 66 KV substations and also to lone EHV 132 KV Dahod substation (fed radialy from Godhra), it is proposed to create new 220 KV substation at Zalod.
220/66 KV Makansar, Dist: Morbi
Considering non-feasibility of additional lines from 132 KV Wankaner substation and critical loading of 132/66 KV Wankaner substation, it is necessary to divert some load from Wankaner system. Further, to provide 2nd source of power supply to heavily loaded 66 KV Rafleshwar, Dhuva etc. substations and to provide connectivity to new substations in the area, it is necessary to have EHV substations in the area. Therefore, it is proposed to create 220/66 KV Makansar substation, to cater future load growth in the surrounding area and to divert the load of 66 KV Dhuva, Bhojpara and Lunsar substations from 132 KV Wankaner substation.
220/66 KV Talaja, Dist: Bhavnagar
Talaja area of Dist. Bhavnagar is having predominantly agriculture demand. Load of the area is being catered through 66 KV substations fed from 220 KV Sagapara & Otha substation. During the poor monsoon and extended dry spell, the agricultural demand is getting drastically increased and there is a dire necessity to supply power to agriculture feeders so as to save the agricultural crops. However, it was observed that the existing transmission and sub-transmission network is not capable of delivering the required power

4. 3. 132 KV Substations:
132/66 KV Mota Dahisara, Dist:Morbi
PGVCL has proposed to create 66/11 KV substation at Mota Dahisara considering long 11 KV feeders, voltage regulation issues and future load growth. Mota Dahisara substation is located 10-12 KM away from the existing 66 KV Pipalia substation. The existing source to 66 KV Pipalia substation is from 66 KV Morbi (220 KV) - Vajepar tap to Pipalia substation is around 25 Km through Dog conductor. There is no other alternate 66 KV network available nearby proposed 66 KV Mota Dahisara substation. 132 KV D/C Varshamedi – Wankaner line is passing in the close vicinity (i.e. 4 RKM) of proposed 132 KV Mota Dahisara substation. Therefore, it is proposed to create 132 KV Mota Dahisara substation which will provide strong source to 66 KV Pipalia, 66 KV Jam Dudhai and other substations in the area.
132/66 KV Tankara, Dist: Morbi
Tankara is a town of Morbi district in Gujarat state. Further, Tankara pocket is under industrial development and numbers of ginning and spinning mills are planned in the surrounding area.

Gujarat Energy Transmission Corporation Limited Page 70 Petition for True Up for FY 2015-16, Multi-Year ARR for FY 2016-17 to 2020-21, Final ARR for FY2016-17 and Tariff for FY2017-18
substations), the main source of 66 KV Tankara substation is 400 KV Hadala substation through 66 KV Hadala – Kagdadai – Neknam – Mitana – Tankara line only. All other lines are normally kept in sock charge because of critical loading of 66 KV single circuit line from main source. Therefore, it is proposed to up-grade existing 66 KV Tankara substation to 132 KV level.
Description of Major Transmission Lines proposed during 3rd Control Period:
GETCO is proposing to lay 4425 CKMs of 400 KV; 4138 CKMs of 220 KV, 459 CKMs of 132 KV & 4519 CKMs of 66 KV transmission lines during FY 2016-17 to FY 2020-21. Description of major transmission lines are as under:
400 KV D/C Wanakbori TPS Unit No.8 – Soja line 400 KV D/C Soja – Zerda line At present there are 7 units of 210 MW each in service at Wanakbori TPS with total 1470 MW installed capacity. Out of the 7 units, first 3 units are evacuating power at 220 KV level and balance 4 units are evacuating at 400 KV level along with a 400/220 KV, 1 x 500 MVA ICT at Wankbori TPS.
Now, GSECL have planned to expand the capacity at Wanakbori TPS by installing unit No. 8 of 800 MW which will have a separate 400 KV switchyard due to accommodating the new unit far away from the existing unit No.7. 400 KV D/C Wanabori TPS Unit No.8 – Soja and 400 KV D/C Soja – Zerda lines are planned to evacuate generated power in North Gujarat area through down-stream of 400 KV Soja & Zerda substations.
400 KV D/C Kasor – Amreli line: 400 KV S/C Hadala – Chorania and 400 KV S/C Chorania – Kasor lines are getting critically loaded owing to increased generation availability at 400 KV level from UMPP, APL, EPGL. Further, during high renewable generation, loading on these lines is getting loaded beyond its design capacity of 615 MW per circuit. 400 KV D/C Kasor – Amreli line is proposed to strengthen and develop new route for power flow between Central Gujarat and Saurashtra region.
400 KV D/C Varsana – Halvad line: 400 KV D/C Halvad – Vadavi line: 400 KV Varsana substation is connected with APL Mundra, UMPP Mundra (through Bhachau substation) and OPGS power plants. Also, nearly 600 MW wind power is also directly connected with Varsana substation. Further, it is already planned to connect 750 MW additional wind power at 400 KV Varsana. In additional to above, huge renewable (wind & solar) potential is available in Kutch area. Existing network may not be capable to handle the anticipated renewable capacity in the area. Also, nearly 500-600 MW wind capacity is already planned to be integrated in the associated network of 400 KV Halvad substation. Local consumption during monsoon is very less in these areas and renewable availability is very high. Therefore, there is a strong need to transfer this power to the load centres surrounding Ahmedabad. Accordingly, it is planned to create 400 KV D/C Varsana – Halvad & 400 KV D/C Halvad – Vadavi lines.
LILO of 400 KV S/C Jhanor – Navsari line at proposed Vav substation: LILO of 400 KV S/C Ukai TPS – Kasor line at proposed Vav substation: Due to reduced generation from gas based generating stations located in South Gujarat area, integrated at 220 KV level, many 220 KV lines are getting critically loaded. 220 KV D/C Ukai – Mota and 220 KV S/C Kosamba – Vav lines are getting loaded beyond its designed capacity of 180 MW per circuit. 400 KV Jhanor, Kosamba & Navsari substations are very well connected with strong 400 KV power sources. Therefore, it is proposed to have LILO of 400 KV S/C Jhanor – Navsari & 400 KV S/C Ukai TPS - Kosamba lines at Vav substation.
400 KV D/C Hadala – Shapar line: 400 KV D/C Shapar – Fedra line: 400 KV Hadala substation is connected with APL Mundra and EPGL Vadinar power plants. Also, Hadala is going to be connected with 220 KV Jamnagar substation wherein huge wind power is integrated in downstream system. Further, it is already planned to connect 400 MW additional wind power at 400 KV Hadala. In additional to above, huge renewable (wind & solar) power available in Bhatia & Bhogat area will be integrated to 400 KV Hadala
Gujarat Energy Transmission Corporation Limited Page 71 Petition for True Up for FY 2015-16, Multi-Year ARR for FY 2016-17 to 2020-21, Final ARR for FY2016-17 and Tariff for FY2017-18
substation through 400/220 KV Kalavad substation. Existing network may not be capable to handle the anticipated renewable capacity in the area. Therefore, for further transfer of this power to the load centres surrounding Ahmedabad & Dholera, it is planned to create 400 KV D/C Hadala – Shapar & 400 KV D/C Shapar – Fedra lines.
220 KV D/C Kheralu – Mathasur line At present, 220 KV Jamnagar substation is fed radially from 400 KV Jetpur substation at 220 KV level through a 220 KV D/C line. Also, huge renewable power is integrated with the downstream network of 220 KV Jamnagar substation at 132 KV & 66 KV level. Therefore, to have a second source for stability and to cater uninterrupted quality power along with smooth evacuation of renewable power, a link line i.e. 220 KV D/C Jamnagar – Hadala line is planned.
220 KV D/C Vadodara (PG) – Jambuva line: 220 KV D/C Vadodara (PG) – Vyankatpura line: Due to reduced generation from gas based generating stations located in South & Central Gujarat area, many 220 KV lines are getting critically loaded. 220 KV S/C Asoj – Jambuva line is getting loaded beyond its designed capacity of 180 MW per circuit on regular basis. Further, PGCIL has already established 765/400 KV substation at Vadodara (PG) near Waghodia. Considering its close vicinity from Vadodara city and also huge demand growth in the surrounding area, PGCIL was requested to have 400/220 KV system at Vadodara (PG) substation to tap the power locally. Accordingly, to have strong source of power supply for Vadodara city and surrounding area, it is proposed to have 220 KV D/C Vadodara (PG) – Jambuva & 220 KV D/C Vadodara (PG) – Vyankatpura lines.
LILO of 220 KV Ukai TPS – Achhalia line No. 2 & 3 at Virpore: 220 KV D/C Virpore – Chikhli line: LILO of 220 KV S/C Vapi - Bhilad line at Chikhli: 220 KV D/C Ukai – Mota, 220 KV S/C Chikhli – Vapi & 220 KV D/C Kakrapar – Vapi lines are getting critically loaded during real time grid operation and it is extremely difficult to handle outage of an element in the area. Therefore, above parallel corridor is planned to have an additional outlet from Ukai TPS towards South Gujarat and its further connectivity to heavily loaded 220 KV Vapi & Bhilad substations through 220 KV Chikhli substation.
220 KV D/C Vondh – Radhanpur line: Due to high renewable availability in the Kutch region, 220 KV D/C Tappar – Shivlakha, 220 KV S/C Shivlakha – Sankhari & 220 KV S/C Shivlakha – Deodar lines are getting critically loaded during high wind season. Therefore, to have an additional outlet from Kutch region to North Gujarat area, 220 KV D/C Vondh – Radhanpur line is planned.
Description of Renovation and Modernization (R&M) System Improvement Scheme: In GETCO network, large number of substations and lines are quite old, some of its equipments viz. CT’s, PT’s, Breakers, Transformers, LA’s are very old, completed their service life, failed in condition monitoring tests i.e change in tan delta, capacitance, Low IR value, heavy oil leakage, out dated technology etc. Also Original Equipment Manufacturers (OEM) have discontinued the supply of spares due to obsolete design and outdated technology. Hence such equipments are required to be replaced. Similarly corrosion takes place on conductor, Insulator, Hardware, earth wire etc. on transmission lines passing through coastal area, creek area & chemical zone. It is required to replace line materials & strengthen the lines. Similarly, it is required to strengthen the footing of line structure at various places where footings got deteriorated.
Such enhancement in the life of substation equipments & transmission line materials are necessary to feed continuous power supply or uninterrupted power supply to DISCOM’s & our valuable consumers.
Scheme has been prepared covering above mentioned criteria for improvement in system – R & M Scheme, which covers following major activities.
a) Replacement of equipments of all voltage class. In many substations equipments namely breakers, CT’s, PT’s, CVT’s battery sets, battery chargers are very old i.e. completed their normal service life, failed in condition monitoring
Gujarat Energy Transmission Corporation Limited Page 72 Petition for True Up for FY 2015-16, Multi-Year ARR for FY 2016-17 to 2020-21, Final ARR for FY2016-17 and Tariff for FY2017-18
tests i.e change in tan delta, capacitance, Low IR value, heavy oil leakage in respect of past results, out dated technology etc. Also, obsolete design, non-availability of critical spares, Low short circuit current capacity, safety etc. are leading factors to consider for replacement of various equipments.
b) Augmentation of substation capacity The industrial / commercial load demand is increasing day by day. Therefore it is essential to increase the capacity of existing sub-station by adding the new transformers or augmenting the existing transformers capacity by higher capacity transformers. This requires 400 / 220 / 132 / 66 kV class transformers with associated equipments. This will help to cope-up the demand of new as well as existing consumers with better reliability.
c) Improvement of Earthing system With increase in loading of sub stations vis-à-vis evacuation of more power from Generating stations, the short circuit level at some sub stations have increased compared to that at the time of commissioning of the sub stations. Simultaneously the aging of earthing system components such as pipe electrode / GI Strips / CI plates over a span of 25-30 years have resulted in erosion and deterioration of earthing components. This situation warrants strengthening of earthing system for the diversion of the ground fault current for protecting precious equipments from likely damages and to avoid serious situation like floating neutral with modern technology.
d) Relay and Protection. Strengthening of protection system RADSS (Static) scheme are to be replaced at 400/220 KV class substations & busbar protection is to be provided at 132 KV class substations) having distinct feature & Bus fault will be cleared within shortest time i.e. within 40-50 m sec which offers system stability
e) Procurement of testing equipments. Purchase of modern testing equipment for various sub stations are required to check & know the healthiness of each equipments and their electrical and mechanical parameters for better operation and maintenance of the sub-stations and transmission lines, which includes computers for remote monitoring, safety tools, modern tools and tackles, testing equipments etc.
Transmission Line under Renovation and Modernization a) Replacement of Conductor, Insulators, Earth wire & line materials with strengthening of structure involve following activities: 220 / 132 / 66 KV transmission lines strengthening are taken up with mainly following activities. Mechanical Strengthening:
The transmission lines which were in service for more than 25 years and situated on coastal areas, creek area, chemical zone etc. are affected due to saline atmosphere and aging. The towers / H-frames of such line are badly affected due to corrosion and chemical reaction. Hence it is required to strengthen the same by providing new members in towers / H-frames, strengthening of stubs & foundation, Earthing, stays, Painting etc.
Replacement of Conductor, Insulators & line materials:
Corrosion takes place due to oxidation on conductor, Insulator, Hardware, earth wire etc. on transmission lines passing through coastal area, creek area & chemical zone. Due to corrosion and aging occurrence of insulator failure, tripping & snapping of conductor takes place which interrupt the power supply. To enhance the life of transmission lines it is required to be strengthened by replacement of insulator, conductor, earth wire, H/W etc.
Enhancement of line capacity:
The Transmission lines are nerves of power flow from Generation station to the end consumers. The Transmission line loading is function of standard capacity of particular size of conductor. Augmentation of line capacity shall therefore be required to meet increased demand of power. In case of exigency, to cater the power demand, Augmentation of line capacity shall be required for a safe Transmission system with high capacity conductor.

b) Link lines In existing network where more than two sub stations are connected on single source, the line is overloaded. Also when a sub station is connected through one source of supply, it is prone to zero power condition. In both such conditions second source is necessary to reduce the over load and to avoid zero power condition respectively. It is proposed to erect link lines for existing overloaded lines and for sub station having single source.
General Renovation and Modernization
1. Maintenance of office building, switchyard & colony: Maintenance of offices, staff quarters, switchyard foundations etc. Purchase of new office furniture, computers and peripherals for modernization and up-gradation of offices, which results in facilitates to office works through fast communication via WAN and Internet. Modernization of office buildings, improves the efficiency of employees.
By way of such activities, following advantages will be achieved:
Improvement in power quality & availability. Reduction in equipment failure. Reduction in transmission losses. Voltage improvement. Adoption of new technology. Better diagnosis with new technology testing equipments. Reduction in accidents Better amenities to employees.

ANNEXURE B: REPORT ON TRANSMISSION PLANNING
Report on Transmission Planning to avoid Transmission Constraints in GETCO system
1. GETCO Transmission Network Planning:
Transmission network system study is done for operation of system under existing grid condition as well as expansion for future load growth. Study is carried out by way of load flow study, short circuit study etc.
The load flow study helps to determine the best location as well as optimal capacity of proposed generating station and sub-stations with new lines at minimum transmission loss. It also suggests improvement to the existing system.
The load flow study also indicates real power, reactive power, and voltage magnitude and phase angle. With the help of system study, the requirement of additional transmission lines / transformers to avoid over loading of existing system, lines for evacuation of power etc. are decided to find most techno economic solution.
The short circuit study is carried out for designing circuit breaker ratings and providing adequate protective scheme of electrical power system based on fault levels.
System study also reveals and indicates low voltage pockets and requirement of compensating reactive power. It also shows voltage profile and transmission losses which are the major parameters that can be known with their permissible limits.
Through system study, one can determine the EHV network required for evacuation of power from generating station and strengthening lines to provide grid stability.
The loading pattern of consumer’s viz. industrial, agricultural, domestic and commercial indicated by various DISCOMs and location of load point determine the requirement of 66 KV substations in the state.
The following standard practice has been considered, as per CEA Transmission Planning
Criteria, for formulation of transmission plan:
Gujarat Energy Transmission Corporation Limited Page 75 Petition for True Up for FY 2015-16, Multi-Year ARR for FY 2016-17 to 2020-21, Final ARR for FY2016-17 and Tariff for FY2017-18
Transmission system planning & design criteria:
Central Electricity Authority (CEA) has evolved transmission system planning & design criteria for the National Electricity Plan. Abstract of Transmission Planning Criteria is as under:
Planning philosophy and general guidelines:
The transmission system is generally augmented to cater to the long term requirements posed by eligible entities, for example, for increase in power demand, generation capacity addition etc. Further, system may also be augmented considering the feedback regarding operational constraints and feedback from drawing entities.
The long term applicants seeking transmission service are expected to pose their end-to- end requirements well in advance to the CTU/STUs so as to make-available the requisite transmission capacity, and minimize situations of congestion and stranded assets.
In line with Section 39 of the Electricity Act, the STU shall act as the nodal agency for Intra- STS planning in coordination with distribution licensees and intra-state generators connected/to be connected in the STU grid. The STU shall be the single point contact for the purpose of ISTS planning and shall be responsible on behalf of all the intra-State entities, for evacuation of power from their State’s generating stations, meeting requirements of DISCOMS and drawing power from ISTS commensurate with the ISTS plan.
The system parameters and loading of system elements shall remain within prescribed limits. The adequacy of the transmission system should be tested for different feasible load- generation scenarios.
The following options may be considered for strengthening of the transmission network. The choice shall be based on cost, reliability, right-ofway requirements, transmission losses, down time (in case of up-gradation and re-conductoring options) etc.
Addition of new transmission lines/ substations to avoid overloading of existing system including adoption of next higher voltage.
Application of Series Capacitors, FACTS devices and phase-shifting transformers in existing and new transmission systems to increase power transfer capability.
Up-gradation of the existing AC transmission lines to higher voltage using same right- of-way.
Re-conductoring of the existing AC transmission line with higher ampacity conductors.
Use of multi-voltage level and multi-circuit transmission lines.
Use of narrow base towers and pole type towers in semi-urban / urban areas keeping in view cost and right-of-way optimization.
Use of HVDC transmission – both conventional as well as voltage source convertor (VSC) based.
Use of GIS / Hybrid switchgear (for urban, coastal, polluted areas etc).
The planned transmission capacity would be finite and there are bound to be congestions if large quantum of electricity is sought to be transmitted in direction not previously planned.
Contingency Criteria:
In normal operation (‘N-0’) of the grid, with all elements to be available in service in the time horizon of study, it is required that all the system parameters like voltages, loadings, frequency should remain within permissible normal limits.
The grid may however be subjected to disturbances and it is required that after a more probable disturbance i.e. loss of an element (‘N-1’ or single contingency condition), all the system parameters like voltages, loadings, frequency shall be within permissible normal limits.
Gujarat Energy Transmission Corporation Limited Page 76 Petition for True Up for FY 2015-16, Multi-Year ARR for FY 2016-17 to 2020-21, Final ARR for FY2016-17 and Tariff for FY2017-18
Criteria for first contingency (‘N-1’)
All the equipments in the transmission system shall remain within their normal thermal and voltage ratings after a disturbance involving loss of any one of the following elements (called single contingency or ‘N-1’ condition), but without load shedding / rescheduling of generation:
Outage of a 132kV or 110kV single circuit,
Outage of a 220kV or 230kV single circuit,
Outage of a 400kV single circuit,
Outage of a 400kV single circuit with fixed series capacitor (FSC),
Outage of an Inter-Connecting Transformer (ICT),
Outage of a 765kV single circuit
Outage of one pole of HVDC bipole.
The angular separation between adjacent buses under (‘N-1’) conditions shall not exceed 30 degree.
Criteria for second contingency (‘N-1-1’)
In the ‘N-1-1’ contingency condition, if there is a temporary fault, the system shall not loose the second element after clearing of fault but shall successfully survive the disturbance.
In case of permanent fault, the system shall loose the second element as a result of fault clearing and thereafter, shall asymptotically reach to a new steady state without losing synchronism. In this new state the system parameters (i.e. voltages and line loadings) shall not exceed emergency limits, however, there may be requirement of load shedding / rescheduling of generation so as to bring system parameters within normal limits.
The steady state voltage shall be maintained within the limits given below:
Voltage (KV – rms) Nominal Maximum Minimum 765 800 728 400 420 380 220 245 198 132 145 122 66 72.5 60

Load demands
The system peak demands (state-wise, regional and national) shall be based on the latest Electric Power Survey (EPS) report of CEA. However, the same may be moderated based on actual load growth of past three (3) years.
The load demands at other periods (seasonal variations and minimum loads) shall be derived based on the annual peak demand and past pattern of load variations. In the absence of such data, the season-wise variation in the load demand may be taken as under:
Sr. Season wise Demand Factor (%) Season / Scenario No. NR WR SR ER NER 1 Summer Peak load (S-PL) 100 95 98 100 100 2 Summer Light load (S-LL) 70 70 70 70 70 3 Monsoon Peak load (M-PL) 96 90 90 95 95 4 Monsoon Light load (M-LL) 70 70 70 70 70 5 Winter Peak load (W-PL) 95 100 100 95 95 6 Winter Light load (W-LL) 70 70 70 70 70
The load power factor at 220kV and 132kV voltage levels may be taken as 0.95 lag during peak load condition and 0.98 lag during light load condition. The STUs shall provide adequate reactive compensation to bring power factor as close to unity at 132kV and 220kV voltage levels.
Generation dispatches and modeling
For the purpose of development of Load Generation scenarios on all India basis, the all India peaking availability may be calculated as under:
Thermal generation:
Sr. Availability Factor (at Availability Factor (at Type of Generation No. Peak Load) Light Load) 1 Nuclear 80 % 80 % 2 Thermal (Coal Based) 80 % 80 % 3 Thermal (Lignite Based) 78 % 78 % 4 Gas Based (CCGT Type) 85 % 50 % 5 Diesel/ or Gas based (Open Cycle) 90 % 50 %
Hydro generation:
Sr. Availability Factor (at Availability Factor (at Season No. Peak Load) Light Load) 1 Summer 70 % 40 % 2 Monsoon 90 % 60 % 3 Winter 50 % 10 %
For planning of new transmission lines and substations, the peak load scenarios corresponding to summer, monsoon and winter seasons may be studied. Further, the light load scenarios (considering pumping load where pumped storage stations exist) may also be carried out as per requirement.
In case of thermal units (including coal, gas/diesel and nuclear based) the minimum level of output (ex-generation bus, i.e. net of the auxiliary consumption) shall be taken as not less than 70% of the rated installed capacity.

GETCO network operational constraints and corresponding network planning:
Though, network is planned with all above planning considerations, transmission network constraints are observed in real time grid operation of Gujarat system. These grid constraints are mainly on account of following reasons:
Non availability of ‘on bar’ generating units due to fuel availability & cost, planned/ forced outages, etc.
Skewed generation dispatch scenario to adhere to the merit order criteria;
Around 4000-5000 MW stranded generation capacity from gas based projects Low PLF from Gandhinagar TPS and Sikka TPS, etc. All these generating stations are integrated at 220 KV/ 132 KV level and being evacuated/ catered in local network. This has resulted into drawl of major power from up-stream 400 KV network.

Sudden changes in demand pattern (delay in monsoon – high agriculture demand, temperature rise – huge urban and rural domestic demand, etc.),
Concentrated generation pockets (huge coal based power plants in western Gujarat, large gas based power plants in South & Central Gujarat, huge wind pockets in Kutch and Jamnagar areas, etc.),
Planned / forced outages of transmission elements,
Phased manner implementation of transmission elements,
Delay in implementation of transmission schemes on account of issues related to land acquisition, RoW problems, forest & environmental approvals, etc.
Grid operation within the prescribed guidelines under Grid Code, Planning Criteria, etc like N-1 contingency criteria to be followed for Grid security,
Variable, uncertain and intermittent renewable power in Kutch and Saurashtra region.
