BACKGROUND

1. Pursuant to the introduction of Long Term Open Access (LTOA) in the inter-State

transmission system vide CERC regulations 2004, POWERGRID had received

overwhelming response from the IPP generation developers seeking LTOA for

the new generation projects proposed to be setup under the de-licensed regime.

2. POWERGRID had received 225 nos. of applications amounting to capacity

addition of about 1,98,438 MW. While processing these applications readiness of

generation projects applied for LTOA were assessed through several rounds of

discussions held with the project developers, wherein status of proposed

generation projects with respect to availability of land, fuel & water linkages,

environment and other statutory clearance were examined in association with the

beneficiaries of concerned regions and CEA. Based on the information furnished

by the applicants, group of generation projects who have made progress on

ground were prioritized and considered for grant of Long Term Open Access.

Accordingly, POWERGRID has already processed and granted or in process of

issuance of LTOA to 90 nos. of applications and balance is at different stages of

processing.

3. It has been observed that the generation projects, for which LTOA has been

sought, are mainly concentrated in small pockets in areas like pit-head in Orissa,

Chhattisgarh, Jharkhand or Coastal sites with port facilities in Andhra Pradesh,

Tamil Nadu or hydel sites in Sikkim etc. These projects are likely to add

generation capacity of about 49,323 MW in which LTOA has been sought for

42,108 MW, The LTOA for these projects has been granted/finalized.

4. All the above applications have no firm beneficiaries and accordingly the

transmission system requirement has been worked out on the basis of target

beneficiaries/regions as informed by the applicants.

5. For meeting the evacuation requirement of above LTOA generation projects likely

to be commissioned progressively from 2011 onwards, construction of nine nos.

high capacity transmission corridors shall be necessary on urgent basis at an

estimated cost of Rs. 58,061 Crores. These transmission corridors have been


Page 2 of 46

evolved and finalized after lot of deliberations with stakeholders in consultation

with CEA at forums including LTOA Meetings, Standing Committee Meetings for

Power System Planning and respective Regional Power Committee meetings.

6. The implementation of finalized transmission system require many pre-

investment project preparation activities like survey, land identification,

preparation of DPR including cost estimates, tendering activity like issuance of

NIT, opening/evaluation of bids etc. which besides incurring cost requires

substantial time. Considering the urgency due to likely commissioning of IPP

projects progressively from 2011 onwards and to enable unhindered

development of transmission system necessary for LTOA projects, POWERGRID

have gone ahead with such activities with the tentative/target beneficiaries given

by the LTOA applicants. In the absence of firm beneficiaries for these generation

projects, the investment of such magnitude would involve high risk. Therefore,

now before initiating physical implementation and making actual investment of

such large magnitude it is necessary to evolve adequate security mechanism to

mitigate the risk involved.

7. In this regard, it may be mentioned that as per para-7.1(4) of the Tariff Policy of

Govt of India published on 6/1/2006, “prior agreement with the beneficiaries

would not be a pre-condition for network expansion. CTU/STU should undertake

network expansion after identifying the requirements in consonance with the

National Electricity Plan and in consultation with stakeholders, and taking up the

execution after due regulatory approvals.”

8. In view of above, POWERGRID vide its petition no. 233/2009 had filed a petition

with the Central Electricity Regulatory Commission (CERC) for grant of regulatory

approval and other relief for execution of evacuation system required in

connection with grant of long-term open access to group of developers. Vide

dated 25/XI/2009, CERC has directed POWERGRID to submit the minutes of the

above meetings and corridor-wise details of the scheme.

9. Accordingly, a Project Inception Report (PIR) covering above mentioned 9 nos of

High Capacity Power Transmission Corridors (HCPTC) have been prepared

which inter-alia comprises of description/justification of each of the corridor in


Page 3 of 46

different sections. The tentative cost estimate for each of the corridor has been

included as a part of the report. These tentative cost has been worked out based

on the unit cost for different categories of transmission line/substation/associated

bays etc, details of the per unit cost considered is given at Annexure-A. It is

pertinent to mention here that these costs are indicative only and actual cost of

each transmission corridor shall be worked out while preparing Detailed Project

Report while seeking its investment approval. Further, the details of the meetings

where such corridors have been discussed/agreed have also been indicated.

Sub-total(Orissa) 10090 3315 2340 225 200 6080 A comprehensive transmission system was planned so as to take care of the evacuation needs of all the future generation projects in Orissa and the same was discussed with generation developers as well as constituents of Eastern, Northern and Western regions during various meetings in the year 2007 and 2008. The comprehensive transmission system was proposed to be implemented in phased manner matching with the program of generation capacity addition. Subsequently, review of progress of generation projects in Orissa was done in various meetings with the project developers between November-2008 to April-2009. Accordingly, the projects mentioned above have been considered under first phase based on the assessment of their actual progress.

As indicated above, the major portion of power from various generation projects of Orissa would have to be exported to power deficit regions like NR & WR. For evacuation and transfer of power from different generation projects in Orissa to NR/WR, a composite high capacity transmission scheme has been planned in view of the Right-of-way problem, so that different generation projects coming up in different time-frame could be integrated. In order to pool power from the generation projects in Orissa, two nos of major 765/400kV pooling substations have been planned at Angul and Jharsuguda. The pooling stations would be interconnected in ring form with 765kV 2xS/c lines. The


Page 6 of 46

Angul substation would be established vide LILO of one ckt of Talchar-Meramundali 400kV D/c line as well Meramundali-Jeypore 400kV S/c line. The Jharsuguda substation would be established vide LILO of Rourkela-Raigarh 400kV D/c line. These LILOs are required for evacuation of initial power from the generation projects pooled at Angul and Jharsuguda. At a later date, these LILOs may be withdrawn so as to reduce the short circuit levels of these substations.

For transfer of power from Angul/Jharsuguda to WR/NR, a high capacity 765kV AC corridor has been planned to NR via WR. The corridor starts from Jharsuguda in ER, reaches upto Bhiwani in NR via important substations like Dharamjaygarh(WR), Jabalpur(WR), Bina(WR), Gwalior(WR) and Jaipur(NR). The corridor also reaches to Indore in WR via Bhopal(WR) and Jabalpur(WR). In this process, three nos of new 765/400kV substations would be created at Dharamjayagarh, Jabalpur and Bhopal. Dharamjayagarh would be an important power hub where power could be pooled from generation projects of Orissa as well as Jharkhand/Bihar in ER for onward transfer to Western part of WR as well as to NR. This substation would be established through LILO of Ranchi-WR Pooling 765kV S/c line. Jabalpur 765/400KV substation would be an important take off point for diversion of power to WR through Jabalpur-Bhopal-Indore route and to NR via Jabalpur-Bina-Gwalior(WR)-Jaipur(NR)-Bhiwani route. Bhopal is also a new 765/400kV substation on the route from Jabalpur to Indore 765kV corridor. 2.0 SCOPE OF WORK The transmission scheme for above mentioned 7 nos. of projects is to be implemented in three parts.

Total 2358 MW A comprehensive transmission system has been planned so as to take care of the evacuation need of all the future generation projects in Sikkim. The transmission schemes are to be implemented in stages matching with the realistic commissioning of generation projects in consultation with Generating Companies / Beneficiaries. The transmission system for above mentioned 9 nos. of projects is to be implemented in two parts; Part-A for evacuation of 1299MW power from the first two projects i.e. Chujachen (99MW) and Teesta-III (1200MW) and Part-B for evacuation of 1059MW power from balance 7 projects.

The power from various generation projects of Sikkim would have to be exported to power deficit regions like NR & WR. For evacuation of power from different generation projects in Sikkim, a need is felt to evolve a composite high capacity transmission scheme in view of the Right-of-way problem in Sikkim, wherein different generation projects coming up in different time-frame could be integrated. In order to pool power from various generation projects in Sikkim, two nos of major pooling substations have been planned at Mangan and New Melli in the upper and lower part of Sikkim respectively. In addition, one small pooling point substation in lower part of Sikkim i.e. Rangpo has also been planned for pooling of power from the generating stations in the vicinity. In view of the tough hilly terrain and scarcity of land for 400kV


Page 16 of 46

Air Insulated Switchyard, it is envisaged that all pooling substations in Sikkim shall be Gas Insulated Switchyard (GIS).

The power from all the future projects of Sikkim is to be brought to a new pooling station in Kishanganj in northern part of West Bengal/Bihar. For this, a 400kV high capacity D/c line is planned from the pooling station Mangan to Kishanganj which is to be LILOed at New Melli Substation. Further, Teesta-V – Siliguri 400kV D/c line would also be LILOed at other pooling station New Melli in order to provide evacuation path for initial generation units as well as reliability to the transfer of Sikkim power to Siliguri/Kishanganj.

The Teesta-III generation project is planned to be evacuated through 400kV D/c line upto Mangan pooling station. However, as Teesta-III is the only project in the upper part of Sikkim in the list of Phase-I generation projects, the Mangan pooling substation is not required to be established now. Accordingly, Teesta-III would be evacuated through Teesta-III–Kishanganj 400kV D/c line. This line would be further LILOed at New Melli, so that the Melli-Kishanganj portion of the line is utilized as a common transmission corridor for evacuation of power from all the Phase-I generation projects. Mangan pooling substation would be established at a later date through LILO of Teesta-III–New Melli-Kishanganj 400kV line for evacuation of power from future generation projects in upper part of Sikkim.

Here, it is to mention that Teesta-III – Kishanganj 400kV D/c line is proposed to be constructed by Teesta Valley Power Transmission Ltd. (a Joint Venture between Teesta Urja Ltd. and POWERGRID).

For onward transfer of power from the generation projects in Sikkim pooled at the Kishanganj pooling substation, strong integration of the pooling substation with the regional grid has been planned. For this, both the high capacity 400kV D/c lines between Siliguri and Purnea are planned to be LILOed at Kishanganj. Further, in order to relieve the critical loading of transmission corridors towards northern region i.e. Purnea-Muzaffarpur 400kV D/c line (quad moose) and Purnea-Biharsharif 400kV D/c line (quad moose, under implementation by private sector), a new corridor i.e. Kishanganj-Patna 400kV D/c line with quad moose conductor has been planned. 2.0 SCOPE OF WORK The common transmission system covered under this corridor is as given below: Part-A : Transmission System for development of pooling station at Kishanganj in Northern part of West Bengal/Bihar

** Chhattisgarh Allocation @35% on a/c of First Right of Refusal As per review on the preparedness of generation projects, it is estimated that about 15,000MW capacity (12 IPPs) may come up in Chhattisgarh (in phase-1 development) progressively in next 3-4 years. Power from these projects need to be transferred to target regions as WR/NR. For evacuation and transfer of power from these different generation projects in Chhattisgarh to NR/WR, there is a need to evolve a composite high capacity transmission scheme in view of the Right-of-way problem, wherein different generation projects coming up in different time-frame could be integrated. However, considering the quantum of power transfer requirement as well as progressive commissioning of generation projects, the entire scheme is proposed for implementation in four nos. different stages. Considering that generation projects are proposed in clusters, it is prudent to pool the power from such clusters at suitable locations. Accordingly, three nos. of 765/400kV pooling substations have been planned namely at Raigarh(Near Kotra), Raigarh(Near Tamnar) and Champa. Power from various generation projects is proposed to be pooled at the above pooling stations through 400kV dedicated transmission lines.

In order to provide interconnections between pooling stations, high capacity 765kV lines are proposed. Towards this, pooling stations at Raigarh (Near Kotra) and Raigarh (Near Tanmar) would be interconnected through 765kV D/c line and Raigarh(Near Kotra) and Champa Pooling station through a 765kV S/c line. For onward transfer of power, it is proposed to further pool power from above pooling station through another pooling station at Raipur. Raigarh Pooling station (Near Kotra) would be connected to Raipur pooling station through 765kV D/c line, similarly Champa would also be connected to Raipur through 765kV D/c lines. However, keeping in view the initial power transfer requirement, above 765kV lines are proposed to be operated at 400kV. In addition to above AC corridors, two nos. high capacity HVDC corridors viz. Raigarh Pool(Near Kotra) to Dhule in WR as well as Champa Pool(WR) to Kurukshetra in NR is also proposed to effect transfer of power to the target regions.

For transfer of power beyond Raipur, a high capacity corridor between eastern and western part of WR namely Raipur-Wardha-Aurangabad 765kV D/c line is proposed which shall be operated at 400kV level initially. Beyond Aurangabad, power is proposed to be transferred through high capacity Aurangabad-Khargar 400 kV D/C (quad) lines. In order to facilitate charging of above pooling stations, 400kV interconnections between Raigarh Pooling Station(near Kotra) and Raigarh(existing) S/s as well as Raipur Pooling station and Raipur(existing) S/s is proposed. However,


Page 26 of 46

these interconnections shall be opened at a later date to avoid high loading on the underlying 400kV system.

Total 4600 3072 857 912 1258 From the above it may be seen that besides SR substantial quantum of power for which long term open access has been sought involves transfer of power to constituents of WR and NR. Therefore, the transmission system required for facilitating long term open access shall include; (i) strengthening of the system in Southern region to facilitate immediate evacuation as well as further dispersal of power in SR grid and (ii) strengthening of WR and NR grids including inter-regional links for transmission of power to the target beneficiaries. The present corridor covers the requirement (i) as mentioned above, the requirement (II) has been covered in the separate corridor - IX. The generation projects under Long-Term Open Access in Krishnapatnam area, as mentioned above in the table are proposed to be materialized in two different time frames i.e. 2010-11 & 2012-13. Further major portion of power from these generation projects are allocated outside Southern region and is to be to be exported to power deficit regions like NR & WR. Apart from above, Krishnapatnam UMPP 4000 MW has been proposed in the same vicinity which is likely to be commissioned in 2013-15 time frame. The transmission system associated with Krishnapatnam UMPP has already been finalized under which two transmission corridors viz. Kurnool and Gooty have been envisaged. Therefore a composite high capacity transmission system was evolved for the LTOA generations corresponding 2012-13 time frame when all the projects in the vicinity shall be available. Further the transmission system has been verified for its


Page 32 of 46

suitability for the 2013-15 time frame when Krishnapatnam UMPP and its transmission system is likely to be available. Accordingly, phasing of transmission system is made to evolve the minimum transmission system that should be available in the intermediate time frame of 2010-11 for meeting the evacuation requirement of Simhapuri and Meenakshi projects which is to be implemented by the project developers. For evacuation and transfer of power from the above generation projects in Andhra Pradesh to NR/WR, following composite high capacity transmission scheme in view of the Right-of-way problem have been evolved, wherein different generation projects coming up in Andhra Pradesh & Tamil Nadu in different time-frame could also be integrated. As mentioned above composite high capacity transmission scheme was evolved for the generation project developer in Krishnapatnam area, Andhra Pradesh. In order to pool power from above generation projects in Andhra Pradesh, a 765/400 kV pooling substation has been planned at Nellore. The Nellore Pooling station would be interconnected by LILO of both circuits of 400 kV D/c (quad) SEPL - Nellore line. For transfer of power from Nellore to constituents of Southern Region, 765 kV AC corridor has been planned to Kurnool/Raichur. For transferring power to NR and WR, inter-regional transmission system has been planned alongwith other generation projects of Southern Region having share in Northern & Western Regions.

2.0 SCOPE OF WORK

The transmission system covered under this corridor shall include the following elements a. Establishment of 765/400 kV, 2x1500 MVA pooling station at Nellore by LILO of

The present corridor covers the requirement (i) as mentioned above, the requirement (II) has been covered in the separate corridor – IX. In the Tuticorin area, apart from the two IPP generation projects mentioned above another generation project under central sector viz. Tuticorin JV TPS (2x500 MW) is under implementation which is likely to be commissioned by February 2012. The transmission system comprising of Tutiocorin – Madurai 400 kV (Quad) D/c line associated with Tuticorin JV has already been finalized and is under implementation. Further, Nuclear Power Corporation of India Ltd. have indicated expansion of their under construction Kudankulam APP (2x1000 MW) by 4 more units of 1000 MW each. Therefore it would be prudent that the transmission corridor constructed from Tuticorin area northwards should be 765 kV to accommodate future requirement. Accordingly composite high capacity transmission corridor is required to be evolved looking into the Right-of-way problems for immediate evacuation as well as for supply of power to target beneficiaries. Keeping above in view, establishment of pooling station has been envisaged at Tuticorin where power from the IPPs project shall be pooled through dedicated transmission lines from their respective switchyard at their own cost. The power so pooled at Tuticorin shall be transmitted upto Madhugiri near Bangalore through high capacity 765 kV transmission lines (initially operated at 400 kV level) via intermediate 765 kV station at Salem. These lines shall be operated at rated 765 kV

These generation projects shall further increase the surplus power of Southern region which to be transferred to WR/NR, therefore, these projects shall be synchronized to Eastern Region for onwards dispersal of power to WR/NR. It may be seen from the above table that Southern Region has share of about 2440 MW and balance power is for Western and Northern regions. The transmission system required for facilitating long term open access shall include; (i) strengthening of the system in Southern region to facilitate immediate evacuation as well as further dispersal of power in SR grid and (ii) strengthening of WR and NR grids including inter-regional links for transmission of power to the target beneficiaries. The present corridor covers the requirement (i) as mentioned above, the requirement (II) has been covered in the separate corridor – IX. The generation projects under Long-Term Open Access in Srikakulam area, as mentioned above in the table are proposed to be materialized in same time frame i.e by end of 12th plan (2011-12). In this time frame Southern region is in surplus and this shall further enhance the surplus power. Out of this surplus power about 5000MW is allocated as target beneficiaries outside SR and is to be exported to power deficit regions like NR & WR. However large number of IPP projects envisaged in Southern region with allocation to WR and NR, the power flow requirement from the East Coast project to SR shall not be there and share of SR from their project shall be displaced by the share of WR/NR in other IPP project located in southern part of SR. Therefore a composite high capacity transmission system was evolved for the LTOA generations corresponding 2011-12 time frame when both the above projects in the

Total 11526 9227 4401 2628 2153 The above power projects are based on coastal sites located on Eastern cost of Southern region spread out starting from Andhra Pradesh to Tamil Nadu. These coastal sites are suitable for establishment of imported coal based power projects, therefore, in addition to above generation projects we are observing overwhelming response from private developers for setting up power projects.

Keeping all the IPP generation projects in Southern region which has been granted / shortly to be granted Long Term Open Access, it is seen that during 2012-15 and beyond SR shall be having surplus power of the order of 16,500-18,000 MW during


Page 44 of 46

peak conditions and about 28,000 MW during off-peak conditions. Here, it is to be mentioned that above surplus includes 14,000 MW of firm power allocated to beneficiaries outside SR. Further this allocation shall increase as some of the IPP generation projects have not indicated their target beneficiaries. Therefore, inter-regional capacity of the order of 16,000-18,000 MW atleast shall be required for catering to the system requirement.

Further the generation additions in SR during 12th plan period under central sector is yet to be finalized which shall further increase the surplus power and SR shall continue to be huge surplus of power. Therefore, the transmission system required for facilitating long term open access shall include; (i) strengthening of the system in Southern region to facilitate immediate evacuation as well as further dispersal of power in SR grid and (ii) strengthening of WR and NR grids including inter-regional links for transmission of power to the target beneficiaries.

The present corridor covers the requirement (ii) as mentioned above, the requirement (i) has been covered in the separate corridor for respective areas. Therefore a composite high capacity transmission system was evolved for the LTOA generations corresponding to 2012-13 time frames when all the generation projects in Southern region which has been granted LTOA shall be available. Further the transmission system has been verified for its suitability for the 2013-15 time frame when Krishnapatnam UMPP and its transmission system is likely to be available. As mentioned above composite high capacity transmission scheme was evolved for the generation project developer in Southern region to facilitate transfer of power to Western region and beyond towards Northern region. 2.0 SCOPE OF WORK The transmission system covered under this corridor shall include the following elements.

a. Sholapur – Pune 765 kV 2nd S/c (1st circuit already covered under transmission

associated with Krishnapatnam UMPP). b. Establishment of 2x1000MVA 765/400 kV station at Orai by LILO of one circuit of
