37.6 During the interactions with SECI/MNRE, it has been indicated that there is a wind potential of about 2500 MW in Tirunelveli area.
37.7 With above back ground, system studies were carried out for evacuation of power from Tirunelveli Pooling Station in a phased manner.
37.8 Phase-I: Studies were carried out with the existing/under-construction transmission system for evacuation of power from Tirunelveli area including 558 MW LTA of CEPL and Tuticorin JV(2x500 MW). The results are enclosed at Exhibits-I. From the study results it has been observed that line loadings are generally in order and wind power upto 1000 MW can be evacuated from Tirunelveli PS with the addition of 1 no of 400/230 kV 500 MVA ICT at Tirunelveli PS (GIS).
37.9 Presently, 2x500 MVA transformers are at advanced stage of commissioning at Tirunelveli PS (GIS) and considering “N-1” of 1 transformer at Tirunelveli PS as per Planning Criteria, additional 1x500 MVA transformer shall be required at Tirunelveli PS for meeting the ‘N-1’ criteria.
37.10 In view of the above, augmentation of 1x500 MVA transformer (3rd) at Tirunelveli PS is proposed for evacuation of 1000 MW generation at Tirunelveli PS.
37.11 Phase-II: System studies were also carried out for evacuation of additional 1500 MW of power injection at Tirunelveli PS as per the wind potential indicated by SECI/MNRE in Tirunelveli area. In this scenario, it is observed that upgradation of the transmission corridor of Tuticorin PS-Salem (Dharmapuri)- Vasanthanarsapur (Madhugiri) to its rated voltage of 765kV is required which is presently charged at 400 kV, for evacuation of total 2500 MW wind generation from Tirunelveli PS (GIS). For this, augmentation of transformation capacity with additional 2x500 MVA, 400/230kV ICTs at Tirunelveli PS is required considering the N-1 contingency. The study results are enclosed at Exhibit-II.
37.12 Accordingly, following is proposed for Phase-II scenario: i.) Upgradation of Tuticorin PS - Salem (Dharmapuri)- Vasanthanarsapur
(Madhugiri) to its rated voltage of 765kV along with associated 765kV bays and
transformers (2x1500 MVA)
ii.) Upgradation of 400/230kV Tirunelveli GIS Pooling Station with 2x500 MVA,
400/230kV transformers along with associated 400kV & 230kV transformer bays.
Further, 5 nos. 230kV line bays (GIS) is also proposed to be included.
37.13 Members may discuss 38. In principal approval for Transmission scheme for Wind Energy Zones (WEZs) in
Southern Region
38.1 Govt of India has set an ambitious target for 175GW renewable capacity by 2022, out of which 60 GW is envisaged to be set up through wind power projects. As part of targeted wind capacity of 60GW by 2022, wind capacity of about 34GW is already achieved in Mar’18. SECI has already tendered/awarded 6050MW of wind capacity in Interstate connected wind bids. Further capacities (wind/solar) are being tendered both by SECI as well as NTPC under Interstate schemes. SECI is also targeting 10 GW scheme for ISTS connected wind power projects in current FY. In view of the wind capacity expansion plan as well as connectivity applications received in ISTS for wind capacity, it is expected that wind capacity may cross the milestone of 60 GW in next 3-4 years.
38.2 NIWE has assessed India's wind power potential of 302GW at 100m hub height with scientific rigor and based on latest available data-sets of wind as well as land geologically spread across India. To identify actual developable wind potential by 2022, several round of discussions were held in Dec’17 & Jan’18 with MNRE, National institute of wind energy (NIWE), STUs, State Nodal Agency of wind potential rich states, POWERGRID & wind developers/IPPs for prioritization of wind energy zones (WEZs) in wind resource rich states for which Interstate transmission infrastructure requirement is to be assessed.
38.3 Based on various inputs like district wise NIWE potential (Rank-I-Wasteland/II- cultivable/ III-forest land), SNA developable potential, pooling station wise wind capacity sanctioned by STU, RE applications received in ISTS by CTU & detailed discussion with wind IPPs/developers, prioritized wind energy zones along with projected capacity in each WEZ were identified, which may come up by 2022 in wind resource rich states. Wind Developers//IPPs also provided detailed inputs on the wind potential zones based on the feasibility of wind farm development considering availability of resources (Wind/Land etc.), land cost, ROW, existing and planned STU transmission system in complex as well as taking account of present regime of competitive wind bids scenario. Further, Interstate transmission infrastructure required for its evacuation and transfer was evolved by POWERGRID. These WEZs were in addition to resource rich pockets which are being developed as part of Green Energy Corridors-ISTS scheme viz. Bhuj & Banaskatnatha (WR), Bhadla (NR), Tirunelvelli/Tuticorin(SR) etc.
38.4 As an outcome of above meetings, five WEZs were identified viz. Koppal (2500 MW) in Karnataka, Kurnool (3000 MW) in Andhra Pradesh, Karur (2500 MW) in Tamil
Nadu, Dwarka (2000 MW) in Gujarat and Osmanabad (2000 MW) in Maharashtra. Copy of the minutes of meeting in this regard is enclosed in Annexure-XVI). Details of WEZs of Southern region is as under
38.5 WEZ in Andhra Pradesh (Kurnool : 3000MW)
As decided in MNRE meeting, it was agreed that Kurnool distt. (3000 MW) should be the priority Wind Energy Zones (WEZ) due to lot of waste land availability, high wind power density (WPD) (good NIWE potential), application received by CTU (about 6000 MW) as well as SNA/STU input for which ISTS substation/infrastructure can be developed/made available. However depending on the land availability for pooling station, to address applications for connectivity in ISTS, same may be planned for common location of Kurnool & Ananthpur distt. Proposed Interstate transmission scheme for evacuation of Wind Power Injection in Kurnool WEZ is as under:
Establishment of 765/400/220kV 3x1500 MVA, 7x500 MVA Pooling station at
suitable location in Kurnool Distt (e.g. near Adoni) Pooling station (near Adoni PS/suitable location in Kurnool distt.) -
Kurnool(new) 765 kV D/c Line 220kV line bays for interconnection of wind projects (10 nos) 1x240 MVAr (765kV) & 1x125MVAr (400kV) bus reactor at Pooling station in
Kurnool Distt.
System study results are enclosed at Exhibit-III.
38.6 WEZ in Karnataka (Koppal : 2500MW)
In the MNRE meeting, it was agreed that Koppal distt should be the priority WEZ (2500 MW) in Karnataka for which ISTS substation/infrastructure can be developed/made available. In the meeting, it was also discussed that in SECI bids, there is a requirement of land acquisition in 9-10 months time period from LOA. In Karnataka most of the wind sites are on cultivable land, which requires pvt companies to obtain permission, therefore site acquisition/development in the Karnataka in SECI timelines is challenging. However considering good wind power density, application received by CTU (about 3000 MW) as well as waste land availability, Koppal distt should be the priority WEZ in Karnataka where ISTS need to be developed/made available on priority. This shall also address applications for connectivity in ISTS. Same may be planned for common location of Koppal & Gadag districts. Interstate transmission scheme proposed for evacuation of Wind Power Injection in Koppal WEZ is as under:

38.7 WEZ in Tamil Nadu (Karur : 2500MW)
It was agreed in MNRE meeting that Karur distt (2500 MW) should be the priority zones for which ISTS substation/infrastructure can be developed/made available. CTU has also received applications for connectivity in ISTS for about 4000 MW in that area. However depending on the land availability for Substation, to address applications for connectivity in ISTS, same may be planned for common location of Karur & Tiruppur distt. This shall also address applications for connectivity in ISTS. Interstate transmission scheme proposed for evacuation of Wind Power Injection in Karur WEZ is as under:
Alternative-1:
Establishment of 6x500 MVA, 400/230 kV Karur Pooling Station LILO of both circuits of Pugalur - Pugalur(HVDC) 400 kV D/c (Quad) line at Karur
PS 220kV line bays for interconnection of wind projects (9 nos) 2x125 MVAr Bus reactor at Karur PS
Alternative-2:
Establishment of 6x500 MVA, 400/230 kV Karur Pooling Station LILO of both circuits of Arasur - Pugalur(HVDC) 400 kV D/c (Quad) line at Karur
PS 220kV line bays for interconnection of wind projects (9 nos) 2x125 MVAr Bus reactor at Karur PS
System study results are enclosed at Exhibit-V.

Minutes of the meeting held to assess the evacuation and transmission infrastructure
requirement for achieving wind power capacity target of 60 GW by 2022
1.0. A meeting was convened under the Chairmanship of Shri Dilip Nigam, Adviser (NSM),
MNRE on 25th January, 2018 in MNRE, New Delhi to assess the evacuation and
transmission infrastructure requirement for achieving wind power capacity target of 60
GW by 2022. The meeting was attended by officials of MNRE, POWERGRID, NIWE,
SNAs of wind resource rich states and Wind IPPs/Developers & IWTMA. The list of
participants is attached at Annexure-I
2.0 POWERGRID made a presentation (copy enclosed) on the data received from SNA/STU
as well as connectivity applications in ISTS in major districts. Based on the above data,
district wise potential was segregated into three categories:
1. Category -I Districts : With High NIWE Potential & High Quantum of Applications
received by CTU
2. Category -II Districts : With High NIWE Potential & Less Quantum of
Applications received by CTU
3. Category -III Districts : With High Quantum of Applications received by CTU but
Less NIWE Potential
List of the above districts is enclosed at Annexure-II.
3.0 In the meeting, Wind Developers//IPP were requested to provide their inputs on the wind
potential zones based on feasibility of wind farm development considering availability
of resources (Wind/Land etc.), land cost, ROW as well as taking into account of present
regime of competitive wind bids scenario. It was decided that based on above inputs,
planning/development of ISTS infrastructure for above identified priority wind
zones/complexes may be carried out. Wind developers/IPP stated that if transmission
infrastructure is made available to above zones (sites/complexes meeting above criteria),
these site will be the low hanging fruits to get first priority in its development towards
realising GOI target of 60 GW wind capacity by 2022. It was decided that objective of
the meeting is to identify wind potential zones along with their priority ranking and
feasible quantum of potential development keeping various aspects into consideration so
that suitable ISTS infrastructure can be identified/evolved.
Developers/IPP also brought to the notice that there is a need for policy intervention at
State level for Intra state transmission infrastructure utilisation for RE. Even though STU
pooling stations are being implemented/planned in RE rich pockets under schemes like
Green Energy Corridors etc, same couldn’t be utilised for ISTS transaction mainly
because of Intra State transmission charges. At some of the ISTS stations in Southern
region, 220kV switchyard are owned by STU which limits its injection for ISTS
transaction again due to above reason. Accordingly, MNRE was requested for some
policy intervention to optimally utilise these existing/under implementation STU
infrastructure.
4.0 M/s NIWE indicated that their wind potential assessment was carried out on 100 m agl
reference. However, due to technological advancement, hub heights are increasing to
120-130 m ,which may increase the CUF of sites by 2-2.5% w.r.t to present estimates.
5.0 It was discussed that out of total envisaged 60 GW wind capacity by 2022, 33 GW
capacity is existing and balance 27 GW is to be established. Out of remaining 27 GW,
based on SNA/STU data it was estimated that about 15 GW capacity is already sanctioned
in Intra state and balance 12 GW or more may come up in ISTS. However, in view of
encouragement of RE by GoI as well as trend of falling wind tariff, it may surpass
envisaged 60 GW target. Therefore, it was decided that as existing GEC-ISTS
infrastructure (Bhuj Pool/ Tirunelvelli PS etc as Wind rich pockets) may cater to wind
injection of 4500-5000 MW, planning for evacuation of additional capacity from other
prioritised wind energy zones may be carried out.
4.0 Accordingly, following was deliberated in the meeting regarding various wind energy
zones (WEZ):
4.1 Tamil Nadu
(i) POWERGRID deliberated that total applications received by CTU in
Tirunelveli/Tuticorin & Karur/Tiruppur districts is about 8000 MW & 4000 MW
respectively which is higher than the balance developable potential
(Tuticorin+Tirunelvelli-3000 MW, Coimbatore/Karur/Tiruppur- 1250 MW)
indicated by NCES, Tamil Nadu. NCES in earlier meeting indicated that though
Coimbatore, Karur, Tiruppur has good wind potential but due to land availability &
ROW issues in Tiruppur & Coimbatore, it is difficult to exploit the potential.
(ii) Wind developers/IPP also informed that since all wind development till date in
Tamil Nadu is on private (cultivable) land, hence acquiring cultivable land in future
is not a big limitation
(iii) Wind developers/IPP also informed that due to huge demand from wind developers,
the land costs have escalated recently in Tirunelveli/Tuticorin region, however due
to high CUF, these two zones (Tirunelveli/Tuticorin & Karur/Tiruppur) will be the
most preferred zones for upcoming SECI ISTS wind bids
Complexes of Karur/Tiruppur districts
(iv) M/s Suzlon opined that based on above criterion, Karur/Tiruppur districts (Palaghat
pass region) may be considered as wind priority zone where existing ISTS
substation 220kV bays at Pugalur, Arasur & Udumalpet are almost exhausted. Wind
developers also informed that according to their assessment complexes in
Karur/Tirupur distt have about 2500-3000 MW additional potential which can be
harnessed and need to be considered as one of the most priority site for development
of new ISTS substation/infrastructure.
(v) M/s Renew indicated that as per their assessment though Karur/Tirupur has good
potential site but due to land availability issues it may be kept in medium priority
zones for development.
(vi) M/s Mytrah representative informed that they will come back after getting inputs
from their Site/HQ. M/s Mytrah subsequently submitted their inputs stating that in
TN Kanyakumari belt has got good potential (1000 MW) site. Other developers
didn’t indicate anything on Kanyakumari belt, however offshore studies in coastal
zones of TN (down south) are being carried out separately. M/s Mytrah also
informed to keep Western part of Karur distt as their 2nd best priority site for
development which has got 2000-2500 MW potential.
Complexes of Tirunelveli/Tuticorin districts
(vii) M/s Suzlon opined that about 4000 MW of potential can be harnessed in
Tirunelveli/Tuticorin complexes as above site are high wind density zones.
POWERGRID informed that they are already developing 400/230kV, 2x500 MVA
Substation under GEC-ISTS scheme where transformation capacity can be
enhanced to total 2500 MVA.
(viii) M/s Renew indicated they have not analysed the above sites yet.
Conclusion for Tamil Nadu WEZ
a) Based on the above inputs, it was agreed by PGCIL that Karur distt should be priority
WEZ (2500 MW quantum) in Tamil Nadu where ISTS transmission infrastructure
needs to be developed/made available, However depending on the land availability for
Substation, to address applications for connectivity in ISTS, same may be planned for
common location of Karur & Tiruppur distt.
b) It was also agreed by PGCIL that as Tiruneveli Pooling Station (PG) capacity is yet to
be harnessed fully, there is no immediate need to plan a new substation in
Tirunelveli/Tuticorin district and same may be kept for next phase.
4.2 Karnataka
(i) POWERGRID informed that KREDL (State SNA) has provided very less balance
developable potential (only about 600 MW) in the state of Karnataka. In earlier
meeting, KREDL had cited the reason of embargo put by KERC on signing of fresh
PPA by DISCOMs.
(ii) POWERGRID indicated that total connectivity applications received by CTU in
Category-I districts i.e. Koppal, Chitradurga & Gadag district is about 3000 MW,
750 MW & 750 MW respectively.
(iii) Developers/IPP also informed that in SECI bids, there is requirement of land
acquisition in 9-10 months’ time period from LOA. In Karnataka also, wind
potential sites are majorly on cultivable land. In GoK policy, for private companies,
agriculture land can be bought only after taking Govt. permission and then
conversion is done. Since the permission and conversion process takes time, site
acquisition/development in the Karnataka in SECI timelines is challenging.
(iv) Developers/IPPs informed that Bellary district is a mining area hence there is
meagre chances of wind development. Belgaum is having a lot of cultivatable land
and hence faces difficulty in development. However, M/s Mytrah indicated
potential of about 1000 MW near Chikkodi in Belgaum distt. It was discussed that
in Bijapur & Bagalkot distt, most of the wind development has already taken place
and KPTCL Intra-state transmission developments are also taking place in these
districts. Therefore these districts don’t come under priority as of now for ISTS
development and may come up in future once the other preferred sites are
exhausted.
(v) M/s Mytrah subsequently indicated requirement of ISTS infra near Basavana
Bagewadi in Bijapur distt, however CTU is not in receipt of applications in Bijapur
distt so far. The other developers didn’t indicate any such requirement. However in
case it is found to be a better site after wind resource assessment by other
developers, its priority can also be kept for next phase of this exercise.
(vi) Regarding Tumkur & Dharwad districts which are classified as Category-III
districts (Low potential & large nos of application), NIWE informed that both are
less potential districts. Wind developers informed that Tumkur district is very near
to Bangalore and land costs are very high and hence not viable to develop and same
applies to Dharwad district as well.
(vii) Chitradurga though is a high WPD site but issues of further development on its
cultivable land portion are a challenge. Therefore its priority can also be kept for
next phase of this exercise.
(viii) M/s Suzlon indicated that in view of the good wind potential & land availability
near Munirabad area in Koppal distt, there is a need to develop new substation near
Munirabad for harnessing of about 1000-1500 MW potential. M/s Renew also
emphasised good potential of Koppal distt of about 1000-1500 MW. M/s Mytrah
Ltd subsequently indicated 2000-2500 MW wind potential toward North of Koppal
distt.
(ix) POWERGRID informed that Koppal & Gadag are contiguous districts and possibly
the new ISTS substation along with transmission interconnections may be planned
near the border of these districts to address the applications of both the districts.
Conclusion for Karnataka WEZ
a) Based on the above inputs, it was agreed by PGCIL that only Koppal distt should be
the priority WEZ (2500 MW quantum) in Karnataka for which ISTS
substation/infrastructure can be developed/made available. However depending on the
land availability for Substation, to address applications for connectivity in ISTS, same
may be planned for common location of Koppal & Gadag distt.
4.3 Andhra Pradesh
(i) In Andhra Pradesh, Kurnool & Anantapur districts were classified under Category-
I (High Potential, large applications) whereas Cuddapah district is classified under
Category-II site (High Potential, less applications)
(ii) As per data provided by NREDCAP (SNA), envisaged balance developable
potential in Anantapur and Kurnool district is about 5300 MW & 3000 MW
respectively.
(iii) POWERGRID informed that Andhra Pradesh has already planned system for more
than 6700 MW under GEC intra state scheme which includes substations like
Hindupur, Urvakonda, Urvakonda-II, Kondapuram in Anantpur distt and Aspiri in
Kurnool distt.
(iv) POWERGRID again emphasised on underutilisation of these infrastructure, if wind
doesnot up in Intra state and duplicity in construction of new system under ISTS
(v) POWERGRID deliberated that total applications received by CTU in Kurnool &
Anantapur districts are 6000 MW & 2000 MW respectively. In Cuddapah district
also, 500 MW quantum of applications are received.
(vi) Wind developers/IPP indicated that though Cuddapah has high NIWE potential, but
due to mining & RoW issues, only about 500 MW can be developed.
(vii) Therefore, it was decided that only Kurnool & Anantapur distt should be the priority
WEZ in Andhra Pradesh where ISTS need to be developed/made available on
priority Accordingly above potential complexes were discussed in specific as
under:
Complexes in Kurnool distt
M/s Suzlon & M/s Renew informed that due to lot of waste land availability as well
as high WPD, around 2500-3000 MW wind potential can be harnessed in Kurnool
district
M/s Mytrah also subsequently intimated that around 2500-3000 MW potential can
be harnessed in Kurnool district
NREDCAP also opined need of a new ISTS substation near Pattikonda in Kurnool
district, in view of good potential availability in that complex in Kurnool distt
Complexes in Anantpur distt
M/s Suzlon & M/s Renew indicated Anantapur distt too has a potential of around
1500-2000 MW & about 2500 MW respectively
Conclusion for Andhra Pradesh WEZ
Based on the above inputs, it was agreed by PGCIL that Kurnool distt should be the
priority WEZ (3000 MW quantum) in AP for which ISTS substation/infrastructure can
be developed/made available. However depending on the land availability for Substation,
to address applications for connectivity in ISTS, same may be planned for common
location of Kurnool & Anantpur distt.
4.4 Telangana
(i) As per data provided by TSREDCO (SNA), envisaged balance developable wind
potential in Mehboobnagar district is about 1500 MW. POWERGRID informed that
they have also received applications for 1200 MW in in Mehboobnagar distt.
(ii) Wind developers/IPPs informed that the Mehboobnagar is having low CUF sites.
Moreover lot of solar plants are coming up near these sites in Mehboobnagar distt
and therefore land acquisition has become an issue in recent times due to land
acquisition activities by the Solar developers. Rangareddy distt too has some potential
(200-300 MW) but have low WPD.
Conclusion for Telangana WEZ
Based on the above inputs, it was agreed by PGCIL that though Mehboobnagar has
wind potential but due to above constraints, it may not be accorded highest priority.
Therefore ISTS transmission development for Mehboobnagar Wind Energy Zones
may be taken up in its next phase.
4.5 Gujarat
(i) In Gujarat, Category-I districts (High Potential, large applications) included Kutch
and Jamnagar/Dwarka Devbhumi. It was seen that there is substantial mis-match
between quantum of connectivity application vis-à-vis balance developable
potential indicated by GEDA. For eg. in Kutch (Bhuj and Bhachau) application
received for about 13,000 MW while balance developable potential by GEDA is
only 1500 MW. Similarly, in Jamanagar/Devbhumi Dwarka districts, application
received is for about 1500 MW while balance developable potential by GEDA is
about 4000 MW.
(ii) NIWE indicated that as per their assessment wind potential in Kutch and
Jamnagar/Dwarka districts are of the order of 45000 MW and 10635 MW
respectively.
(iii) Developers indicated that potential of about 8000 MW and 1500 MW can be
developed in Kutch and Jamnagar/Dwarka Devbhumi districts respectively.
(iv) For category-II (High Potential, less application) districts viz. Amreli, Bhavanagr
and Rajkot also have moderate NIWE potential, however no applications are
received in above districts so far except in Rajkot for about 600 MW.
Developers informed that in Bhvangar and Amreli district, land availability
constraint may arise due to nearby Gir sanctuary. However developers informed
that offshore wind potential zones have been identified off the shores of Amreli and
Bhavnagar districts. A substation can be planned to cater the offshore wind potential
around these districts.
Director, MNRE stated that offshore wind potential development is in very nascent
stage at this juncture and planning a substation for offshore wind farms is too early.
(v) Developers also stated that near Rajkot, moderate potential exist but being a fast
growing city (Rajkot), getting land in this urban area would be very difficult
therefore this cannot be considered as a wind priority zone and may be taken up in
next phase.
Complexes of Kutch districts
(vi) M/s Renew mentioned that Kutch distt possess about 8000 MW wind potential
which can be further segregated into two wind complex one of around 6000 MW
towards west of Bhuj and around 2000 MW in Northeast of Bachau in above distt.
(vii) M/s Suzlon also opined that about 8000 MW of potential can be harnessed in Kutch
district as many sites are having high wind density and good CUF.
(viii) POWERGRID informed that they are already developing 765/400 kV, 2x1500
MVA Bhuj Pooling station under GEC-ISTS scheme which can evacuate approx.
3000-3500 MW power. Further, connectivity in ISTS is also provided to applicants
for about 700 MW quantum at 400/220kV, 2x315 MVA Bhimasar (Bachau)
Substation.
Complexes of Jamnagar/Devbhumi Dwarka districts
(ix) M/s Renew indicated that as per their assessment Jamnagar/Devbhumi Dwarka
districts have potential of about 2000 MW. There is no ISTS substation is available
in Saurashtra region of Gujarat. Therefore considering good WPD and land
availability in Dwarka/Jamnagar distt , ISTS infrastructure may be planned on
priority in this region.
(x) POWERGRID informed that GETCO has already planned a 400/220kV Substation
in Bhogat to cater to wind injection requirement in Dwarka/Jamnagar distt.
Conclusion for Gujarat WEZ
a) Based on the above inputs, it was agreed by PGCIL that Dwarka distt should be the
priority WEZ (2000 MW quantum) in Gujarat where ISTS infrastructure need to be
developed/made available on priority.
b) It was also agreed by PGCIL that in view of implementation of high capacity Bhuj
substation, planning of a new substation in its near vicinity may be taken up later
on based on the developments taking place in that area.
4.6 Maharashtra
(i) In Maharashtra under category-II distt (High Potential, less applications),
Ahmednagar, Dhule, Nashik, Sangli and Satara, distt are having high NIWE
potential of the order of 5700 MW, 4400 MW, 5000 MW, 10450 MW and 8476
MW respectively. However, POWERGRID did not receive any application in these
districts. Developers informed that though Satara and Sangli distt have high NIWE
potential of which some potential is already harnessed but due to practical
limitations like forest land, local issues and eco sensitivity of Western Ghats, further
development is constrained. Further due to above issues, nothing much has
happened in wind development in past 3 years in these districts.
(ii) Category-III (less Potential, large applications) districts in Maharashtra includes
Beed, Osmanabad, Aurangabad and Solapur which are having potential about 3000
MW, 1500 MW, 600 MW and 500 MW respectively. Developers indicated wind
potential in Maharashtra can be harnessed in Beed and Osmanabad districts as
present wind installed capacity is quite less and land is available in these districts.
Further, they also confirmed that Aurangabad and Sholapur districts are not having
developable potential. Same was confirmed by MEDA also.
(iii) POWERGRID informed that they have also received applications for 2000 MW &
1000 MW in Osmanabad/Latur and Beed distt respectively. MEDA also informed
that joint wind resource assessment has been carried out by MEDA & NIWE in
Solapur/Osmanbad/Latur, and out of 409 sites, only one site is found suitable in
Latur. However, Beed/Latur distt has got more waste land available for the
development.
(iv) M/s Suzlon indicated that in view of less wind installed capacity & ample land
availability in these distt, total about 1500-2000 MW potential can be harnessed in
both the distt.
(v) M/s Renew also emphasised good potential of about 1500 MW & 1000 MW in
Osmanabad & Beed distt respectively.
Conclusion for Maharashtra WEZ
Based on the above inputs, it was agreed by PGCIL that Osmanabad should be the priority
WEZ (2000 MW quantum) in Maharashtra where ISTS need to be developed/made
available on priority but with lowest ranking. However, depending on the land availability
for substations, a common substation for Beed & Osmanabad may be planned to address
applications for connectivity in ISTS.
4.7 Madhya Pradesh
(i) It was noted that only one district (i.e Shajapur) is having about half of the NIWE
potential (3250 MW) of Madhya Pradesh, however the same has low CUF sites. It
was further noted that no applications are received by CTU in Shajapur so far.
Further, Shajapur is also having high solar radiation, where M/s RUMS is planning
solar parks (about 1000 MW).
(ii) POWERGRID stated that they have received various applications of the order of
200-300 MW each in 4-5 districts viz. Betul, Dhar, Ashoknagar, Rajgarh & Sehore,
which may be provided connectivity to nearby ISTS substations. However as per
NIWE above sites are in low CUF range.
(iii) MPPTCL earlier intimated that they had already planned and implementing
transmission infrastructure for its sanctioned wind projects (3300 MW).
Conclusion for Madhya Pradesh WEZ
Based on the above inputs, it was agreed by PGCIL that presently no new ISTS substation
is required in Madhya Pradesh, however, if a substation is planned in Shajapur to cater
the solar park, provision can be kept to accommodate the wind generation also.
4.8 Rajasthan
(i) In Rajasthan, Jaisalmer district was classified under Category-I (High Potential,
large nos of application) whereas Jodhpur district is classified as Category-III site
(less Potential, large applications). Barmer is also categorised in Category –II distt
(High Potential, less applications)
(ii) POWERGRID deliberated that total applications received by CTU in Jaisalmer &
Jodhpur districts are about 4000 MW & 1500MW respectively. In Barmer district,
only 200 MW of applications are received.
(iii) As per data provided by RRECL(SNA), envisaged balance developable potential
in Jaisalmer district is about 2000 MW, whereas no developable potential in future
is envisaged in Barmer & Jodhpur districts
(iv) Wind developers opined that Jaisalmer district, though has low CUF, is best
potential wind site in Rajasthan having about 4000MW of wind potential.
However Jaisalmer being a low CUF wind zone, wind capacity may be developed
in subsequent stages when other sites in various states are exhausted or if there is
major advancement in wind turbine technology for harnessing the potential from
low CUF sites
(v) In Jodhpur, despite low NIWE potential, about 1500MW application is received
by CTU. Wind developers suggested that Jodhpur has about 1500-1600MW wind
potential which will be developed at a later stage with advancement in wind turbine
technology.
(vi) POWERGRID indicated that they are already developing 765/400/220kV Bhadla
PS in Jodhpur distt whereas 765/400kV (with a provision for 220kV) Fathegarh
PS is coming up through TBCB route in Jasialmer distt for various Solar Parks.
Therefore wind projects may be provided connectivity on those stations based on
infrastructure availability.
Conclusion for Rajasthan WEZ
Based on the above inputs, it was agreed by PGCIL that as Rajasthan is having low
priority wind sites and ISTS transmission infrastructure is already being developed for
solar parks, additional ISTS infrastructure for wind project may be planned in next phase
based on the developments in western Rajasthan.
Summary of meeting discussions:-
a) Based on the earlier SNA/STU inputs and information provided by various wind
IPPs/Developers, following was agreed by PGCIL as prioritized wind energy zones for
planning/development of additional ISTS infrastructure:
Priority
Ranking
State District/Complex Quantum (MW)
(Approx,)
1 Karnataka Koppal
2500 MW
2 Andhra
Pradesh
Kurnool
3000 MW
3 Gujarat Dwarka
2000 MW
4 Tamil Nadu Karur 2500 MW
5 Maharashtra Osmanabad 2000 MW
b) POWERGRID (CTU) to evolve transmission plan for above prioritized wind energy zones
to facilitate evacuation & transfer of quantum indicated against each of these WEZ.
c) As high transmission capacity already exist /being implemented in some of the other quality
potential wind zones viz. Bachau & Bhuj in Kutch distt (Gujarat), Tirunelvelli/Tuticorin
distt (Tamil Nadu), CTU informed that further ISTS development may be taken up in next
phase of this exercise based on subsequent developments
Meeting ended with a vote of thanks to the Chair.
