Transmission System strengthening for potential solar energy

zones (11.1GW) –Phase -II in Northern Region (8.1GW under ISTS

and balance 3.0GW under Intra-State by RVPN).

Transmission System for Solar Energy Zones (SEZs) in Rajasthan under Phase-II

involving Hybrid system with EHVAC and VSC based HVDC was discussed and

technically agreed in the 4th NRSCT meeting held on 25/07/19. Accordingly, the

details of the scheme, justification, estimated cost and its tariff impact, results of the

system studies, study assumptions, stakeholder consultation/approval details etc.

were uploaded on CTU website on 14/08/2019 and forwarded to

stakeholders(Generators, STUs, RLDCs, SLDC & Distribution Licensees) for their

observations by 28/09/2019.

Subsequently, the transmission system was again taken up in 5th NRSCT meeting

held on 13/09/2019. During the meeting, various alternatives, viz. EHVAC system

and Hybrid system with EHVAC and VSC based HVDC system were discussed. It

was observed that it would be difficult to implement VSC based HVDC transmission

system by Dec’21 matching with anticipated RE generation projects. Further, Hybrid

of HVDC and AC system is found to be about Rs. 4500 – 5000 Cr. costlier compared

to AC system. Considering above aspects as well as phased implementation of

generation projects, EHVAC transmission system alongwith STATCOMs for reactive

power control was agreed in 5th NRSCT meeting (MOM awaited).

Considering above, details of the revised scheme, justification, estimated cost and its

tariff impact, results of the system studies, study assumptions, stakeholder

consultation/approval details etc. are attached for stakeholders(Generators, STUs,

RLDCs, SLDC & Distribution Licensees) observations, if any, latest by 05/10/2019 at

4.0 OBJECTIVE AND JUSTIFICATION

Government of India has set a target for establishing 175 GW renewable capacity by

2022, which includes 100 GW from Solar and 60 GW from Wind. MNRE vide its order

dated 08.06.2018 had constituted a Sub-Committee to identify ISTS connectivity for

renewable energy projects from potential solar energy zones (SEZs) and potential wind

energy zones (WEZs) of about 50 GW and 16.5 GW respectively. SEZs and WEZs

envisaged in 7 RE rich states (Tamil Nadu, Andhra Pradesh, Karnataka, Gujarat,

Rajasthan, Maharashtra and Madhya Pradesh) were identified by SECI in association

with MNRE in consultation with RE power developers.

To ease implementation of transmission infrastructure, it was proposed to bifurcate these

requirements in two phases. A total of 20 GW solar & 9 GW wind projects has been

planned in Phase-I (up to Dec’2020) and 30 GW solar & 7.5 GW wind has been planned

for Phase-II (Dec’ 2021). For Northern Region, the same translates into a requirement of

10 GW solar in Phase-I (up to Dec’2020) and 10 GW solar in Phase-II (Dec’2021)

totaling to 20 GW. The details of SEZs in Northern Region are given below:

MNRE has subsequently revised Solar Potential complexes details in Rajasthan

for development by 2020/2021 in two phases, which is as under:

District Taluk/Tehsil Ph-1(GW) 2020 Ph-2(GW)

2021 Total

Bikaner Koyalat /Pugal 1.85 3.15 5.00

Total 8.90 11.1 20

Out of total 20 GW REZ [Solar] in Rajasthan, transmission system for 8.9 GW in

Bhadla (3.55 GW), Fatehgarh (3.5 GW), Bikaner (1.85 GW) complexes under

Phase-I, has been taken up for implementation. Out of this, Stage-II connectivity

and LTA applications have been received for about 8 GW and 6 GW respectively.

In the 3rd meeting of NRSCT held on 24/05/2019, the transmission system for

integration of balance 11.1 GW solar potential in Rajasthan [Phase –II :11.1GW]

(Out of total 20 GW REZ [Solar]) from Ramgarh/Kuchheri (4 GW), Bikaner (3.15

GW), Bhadla (1.75GW) & Fatehgarh (2.2 GW) was deliberated. RVPNL

highlighted that the intra-state EHV transmission in Western Rajasthan is

sufficient to evacuate about 10 GW RE projects (7.4 GW already commissioned

and 1.3 GW under implementation). In addition to this, 2 GW, 2.1 GW and 2.211

GW of RE capacity addition is expected in the year 2020-21, 2021-22 and 2022-

23 respectively. For evacuation of this additional 6.3 GW RE capacity,

upgradation of 400kV Jodhpur (Kakani) S/s to 765kV level along with its

interconnections with Phagi 765/400 kV GSS and 400kV interconnections.

It is to mention that additional RE capacity of 4.1 GW (3.1 GW Solar & 1 GW

wind) in time frame of 2021-22 is planned by Rajasthan in Intra state, which

includes 3 GW Solar located in Jaisalmer (2.1 GW), Jodhpur (0.7 GW) & Bikaner

Area (0.2 GW). Therefore after accounting for development of above Solar

generation (3 GW) in Intra state network in similar pockets, transmission system

for only 8.1 GW (Ramgarh/Kuchheri (1.9 GW), Bikaner (2.95 GW), Bhadla

(1.05GW) & Fatehgarh (2.2GW) of RE potential is required to be planned under

ISTS as compared to 11.1 GW system that has been proposed earlier and it was


of 11

decided that that a joint study meeting would be convened to further deliberate on

the scheme.

A joint study meeting was convened on 17/06/2019 & 18/06/2019 at

POWERGRID, Gurgaon, wherein, the representatives from CTU, POSOCO,

Haryana, Punjab, Himachal Pradesh, Rajasthan and Delhi were present. No

representative from UPPTCL, PTCUL and JKPDD attended the meeting. All the

State representative furnished their load generation balance as well as existing

and planned RE generations in their respective states. The comments furnished

by the constituents were discussed and accordingly the load flow study was

revised. Subsequently, PTCUL representative also got updated the network

pertaining to them.

As advised by the constituents during above joint study meeting two alternatives,

viz (i) AC Transmission system (ii) Hybrid Transmission system involving VSC

based HVDC were proposed for evacuation of 8.1 GW under ISTS as part of

Phase-II. During 4th NRSCT meeting, after detailed deliberations, considering

technical advantages of Hybrid Transmission system involving VSC based HVDC

were agreed for evacuation of 8.1 GW under ISTS as part of Phase-II.

Subsequently, the transmission system was again taken up in 5th NRSCT

meeting held on 13/09/2019. During the meetings, various alternatives, viz.

EHVAC system alternatives and Hybrid system with EHVAC and VSC based

HVDC system alternative were discussed. It was observed that it would be

difficult to implement VSC based HVDC transmission system by Dec’21 matching

with anticipated RE generation projects. Further, Hybrid of HVDC and AC system

is found to be about Rs. 4500 – 5000 Cr. costlier compared to AC system.

With regard to EHVAC transmission system, it was discussed that as per

technical standards of CEA, Renewable Generators shall be capable of supplying

dynamically varying reactive power support so as to maintain power factor within

limits of 0.95 lagging to 0.95 leading. Assuming length of dedicated line as 50 km,

reactive power loss of about 30 MVAr is envisaged for 300 MW on 220kV S/c

line. Accordingly, in the absence of proper reactive power support to transmission

system, compensation is required to be provided near RE Generation Pooling

Stations.

During fault conditions in the absence of conventional generator & low short

circuit levels in close proximity, grid/voltage stability would be a major concern.

Due to persistence of low voltage in the network, there could be cascading effect

of multiple RE generation tripping due to breach of LVRT triggers. This could lead

to further fall in system voltage due to generation loss and may lead to voltage

collapse in the system. In view of above, dynamic reactive power support at ISTS


of 11

pooling station is required to maintain Grid parameters within acceptable limits

with variation in generation.

It is also observed from simulation studies that many line & bus reactors are

required to be switch off to operate the grid in high RE scenario. Considering

large scale integration of Renewable Energy Sources (both State & ISTS)

expected in Western Rajasthan, Ramp up/down of generation is envisaged to be

very fast. In such a scenario, manual switching ON/OFF of Reactors may not be

practically feasible & STATCOM controllers may be used for switching in/out

nearby Reactors.

Considering above aspects as well as phased implementation of generation

projects, EHVAC transmission system alongwith STATCOMs for reactive power

control was agreed in 5th NRSCT meeting as “Transmission System Strengthening

for potential Solar Energy Zones (SEZs) - Phase-II in Northern Region” to cater to the

future potential (8.1 GW) at the complexes in Ramgarh, Fatehgarh,

Bhadla/Phalodi & Bikaner.

Considering power transfer from Solar potential of various complexes in Western

Rajasthan i.e. Ramgarh, Fatehgarh, Bhadla/Phalodi & Bikaner, the technically

agreed transmission system includes establishment of 400/220kV pooling station

near Ramgarh/Kuchheri in Distt Jaisalmer (Ramgarh-II PS) and near Bikaner

(Bikaner-II PS). The scheme also includes augmentation of transformation

capacity at Fatehgarh-II PS, Bhadla-II PS and Bikaner (PG).

For interconnection of above new pooling stations with existing/under

construction transmission system and to strengthen existing transmission system,

Ramgarh-II PS –Fatehgarh-II PS 400 kV D/c(Twin HTLS), Ramgarh-II PS –

Jaisalmer-II (RVPN) 400 kV D/c(Twin HTLS), Fatehgarh-II PS – Bhadla-II PS

765kV D/c(2nd ), Bikaner-II PS – Khetri 400kV 2xD/c(Twin HTLS), Bikaner-II PS –

Bikaner (PG) 400kV D/c(Quad) have been agreed. For onward dispersal of

power, development of high capacity corridors viz. Khetri - Bhiwadi 400kV

D/c(Twin HTLS), Khetri - Narela 765kV D/c, Bhadla-II – Sikar-II 765kV 2xD/c,

Sikar-II – Neemrana 400kV D/c(HTLS) and Sikar-II – Aligarh 765 kV D/c also

been agreed. The scheme also envisages establishment of 765/400 kV Narela

S/s, LILO of Meerut – Bhiwani 765kV S/c line at Narela S/s, Maharanibagh –

Narela 400kV D/c(Quad) and Gopalpur-Narela 400kV D/c(Quad) lines. Further,

STATCOMs have been agreed at Bikaner(± 300 MVAr, 2x125 MVAR MSC , 1x125

MVAr MSR), Bhadla-II (± 600 MVAr, 4x125 MVAR MSC , 2x125 MVAr MSR) and

Fatehgarh-II (± 600 MVAr, 4x125 MVAR MSC , 2x125 MVAr MSR) for reactive power

support & dynamic stability enhancement.


of 11

For optimal utilization of transmission system, it was agreed to reverse the

conventional power flow of Balia – Bhiwadi HVDC, i.e 2000 MW power from

Bhiwadi to Balia.

In addition, suitable reactive compensation in the form of Bus reactor at above

substations as well as switchable line reactors on EHV AC lines are also agreed.

5.0 COST-BENEFIT ANALYSIS INCLUDING LONG TERM ECONOMIC ADVANTAGE

The annual transmission charges for the subject scheme at an estimated cost of

about Rs. 12442 Cr would be about Rs. 2115 Cr. The above transmission

system shall enable transfer of power from 8100 MW solar capacity. Such

quantum of power shall translate into annual energy of about 17739 MU [Energy in

MU = (8100x0.25*xx8760) / 103]. If we consider rate of energy as Rs. 2.5 per unit on

the conservative side then the total annual energy cost works out to be about Rs.

4435 Crs.

In other words, the system proposed under the subject scheme whose annual

transmission charges is Rs. 2115 Crs shall enable ISTS grid to handle energy

amounting to Rs. 4435 Crs.

In addition to the above tangible benefits, the development of proposed

transmission scheme shall also provides intangible benefits in the way of

providing vital transmission system for evacuation of clean & green solar energy.

This shall also go a long way in nation’s energy security & sustainability at

affordable prices along with addressing climate change concerns.

* Solar CUF@25% has been considered as per SECI information.

6.0 TIME FRAME / PHASING OF THE IMPLEMENTATION OF THE SCHEME The transmission scheme was envisaged based on the potential of Solar Energy

in Western Rajasthan and Government of India target for establishing 175 GW

renewable capacity by 2022. In a meeting regarding prioritization of transmission

system associated with 66.5GW potential RE capacity already planned held on

30.08.2019 at CEA, SECI stated the transmission schemes associated with RE

capacity addition in Rajasthan , needs to be taken up on priority. Minutes of the

Meeting are attached at Annexure-III. Accordingly, the scheme is required to be

completed by December, 2021.

3.0 Transmission System for evacuation of Power from potential solar energy zones Phase -II in Northern Region.

3.1 CEA stated that Govt. of India had set a target for establishing 175 GW renewable capacity by 2022, which includes 100 GW Solar, 60 GW Wind generation capacity. MNRE vide its order dated 08.06.2018 had constituted a Sub-Committee to identify ISTS connectivity for renewable energy projects from potential solar energy zones (SEZs) and potential wind energy zones (WEZs) of about 50 GW and 16.5 GW respectively. SEZs and WEZs envisaged in 7 RE rich states (Tamil Nadu, Andhra Pradesh, Karnataka, Gujarat, Rajasthan, Maharashtra and Madhya Pradesh) were identified by SECI in association with MNRE in consultation with RE power developers.

To ease implementation of transmission infrastructure, it was proposed to bifurcate these requirements in two phases. A total of 20 GW solar & 9 GW wind projects has been planned in Phase-for Phase-10 GW solar in Phase- 10 GW solar in Phase-totalling to 20 GW. The details of SEZs in Northern Region are given below:

3.2 Out of total 20 GW REZ [Solar] in Rajasthan, transmission system for 8.9 GW in Bhadla (3.55 GW), Fatehgarh (3.5 GW), Bikaner (1.85 GW) complexes under Phase-I, was technically agreed in the 2nd meeting of Northern Region Standing Committee on Transmission (NRSCT) held on 13.11.2018.

3.3 In the 3rd meeting of NRSCT held on 24.5.2019 the transmission system for integration of balance 11.1 GW solar potential in Rajasthan [Phase II :11.1GW] (Out of total 20 GW REZ [Solar]) from Ramgarh/Kuchheri (4 GW), Bikaner (3.15 GW), Bhadla (1.75GW) & Fatehgarh (2.2 GW) was deliberated. In the meeting RVPNL highlighted that the intra-state EHV transmission in Western Rajasthan is sufficient to evacuate about 10 GW RE projects (7.4 GW already commissioned and 1.3 GW under implementation). In addition to this, 2 GW, 2.1 GW and 2.211 GW of RE capacity addition is expected in the year 2020-21, 2021-22 and 2022-23 respectively. For evacuation of this additional 6.3 GW RE capacity, 765/400 kV Jodhpur GSS (Hingola) along with its interconnections with Phagi 765/400 kV GSS has been planned. Subsequently, RVPNL has provided the modified proposal for evacuation of additional RE capacity. The plan comprised upgradation of 400kV Jodhpur (Kakani) S/s to 765kV level along with its interconnections with Phagi 765/400 kV GSS and 400kV interconnections.

An additional RE capacity of 4.1 GW (3.1 GW Solar & 1 GW wind) in time frame of 2021-22 has been planned by Rajasthan in Intra state, which includes 3 GW Solar located in Jaisalmer (2.1 GW), Jodhpur (0.7 GW) & Bikaner Area (0.2 GW). Therefore, after accounting for development of above Solar generation (3 GW) in Intra state network in similar pockets, transmission system for only 8.1 GW (

) of RE potential was required to be planned under ISTS as compared to 11.1 GW system that has been proposed earlier and it was decided that that a joint study meeting would be convened to further deliberate on the scheme.

MoP vide its OM dated 14.6.2018 had notified the long term RPO trajectory, solar and non-solar, uniformly for all the States, wherein, RPO (%) (of total consumption Excluding Hydro) 10.5% for Solar and 10.5% for non- solar has been mentioned for 2021-22.

4.0 Modifications in the Transmission schemes for Solar Energy Zones (SEZs) in Rajasthan (8.9 GW)

4.1 transmission system for Solar Energy Zones (SEZs) in Rajasthan (8.9 GW) under Phase-I, was technically agreed in the 2nd meeting of Northern Region Standing Committee on Transmission (NRSCT) held on 13.11.2018. which inter-alia includes Length of this transmission line was estimated to be approx 100 km (as the estimated length of Fatehgarh-Bhadla transmission line was also about 100 km). Hence no reactive compensation was proposed for this line. However, it has come to notice that the route length for which Fatehgarh Bhadla Transmission Limited has got approval for Fatehgarh-Bhadla 765 kV D/c line is 145 km rather that earlier estimated 100 km. Also, survey for Fatehgarh II- Bhadla II has been done by BPC which indicated the route length to be 187 km in view of the proposed extension in the boundaries of the protected area for Great Indian Bustard. Therefore, reactive compensation needs to be provided for

Annexure-III

Annexure-IV Study Assumptions

1. Studies has been carried out for various load generation scenarios i.e. solar

maximized scenario (for 8.1 GW SEZ based on future potential in Rajasthan) as

well as peak demand scenario for 2021-2022 time frame.

2. All India Demand is considered as per the 19th EPS of CEA (2021-22). For peak

demand scenario, regional demand has been considered as per the 19th EPS.

Based on the discussions & past trends, for solar maximized scenario, demand

has been considered as about 90% of the peak demand of 19th EPS for various

regions except for Northern region where it is considered as about 95% of the

peak demand.

3. In the studies, all India transmission network up to 220kV level has been

simulated. This includes, existing and well as under construction transmission

network incl. high capacity transmission corridors and Green Energy Corridors.

4. Considering envisaged RE (wind & solar) capacity addition and to achieve Load-

generation balance, Thermal generation dispatch is reduced upto 55%, wherever

required. At some of the locations, thermal generation is even needed to be

backed down.

5. For RE (Solar) maximized scenario, Solar generation dispatch in Rajasthan ISTS

SEZ is considered as 100%, whereas Rajasthan wind generation dispatch is

considered as 30% (Intra Solar is considered as 80%). In peak demand scenario

(evening), no Solar generation is considered whereas Rajasthan wind generation

dispatch is considered as 70%.
