MINUTES OF MEETING
Minutes of the Joint meeting of the Standing Committees of Power System planning of SR and WR, held on 26-Dec-2013 at SRPC, Bangalore
List of participants is given at Annex-I.
1.0 Member Secretary, SRPC welcomed Chairperson, CEA and the participants in SRPC to the joint meeting of the Standing Committees of Southern and Western regions.
Chairperson, CEA welcomed the participants from Southern and Western regions and introduced the concept of GNA in the context of planning of ISTS network. She said that the GNA would provide flexibility in procurement of power to the States and also ensure that adequate ISTS network gets built to meet their load demand. She added that before formally sending the concept paper to CERC in the context of amendment to the LTA/MTOA regulations, it would be pertinent to discuss the GNA concept with all the stakeholders and seek their valuable suggestions.
Chief Engineer(SP&PA), CEA said that the main agenda for this joint meeting is to discuss the concept paper on General Network Access i.e. GNA. It is also proposed that the issue of transmission system for evacuation of power from Yeramarus (2x800 MW) and Edlapur (1 x 800 MW) Thermal power generation in Karnataka, for which CEA has already given its in-principle approval, shall be discussed. He requested Director(SP&PA), CEA to take up the agenda items for discussion.
2.0 Transmission system of KPTCL for evacuation of power from Yeramarus (2x800 MW) and Edlapur (1 x 800 MW) Thermal power generation.
2.1 Director(SP&PA), CEA mentioned that the transmission system for evacuation of power from the Yeramarus (2 x 800 MW) and Edlapur (1 x 800 MW) Thermal power generation project in the State of Karnataka was discussed in the meeting held in CEA with KPTCL and Central Transmission Utility i.e. Power Grid Corporation of India Ltd. on 14th November, 2013. Based on the studies carried out and discussions held in CEA, it was brought out that the total transmission system may be implemented in two stages.
5
Stage-I : Transmission scheme for evacuation of power from Yeramarus (2 x 800 MW) TPS, and
Stage-II: Transmission scheme for evacuation of power from Edlapur (1 x 800 MW) TPS.
CEA, on 19-11-2013 has given its ‘In-principle’ approval to KPTCL so as to enable them carry out preparatory activities for these schemes. He presented the results of the system studies that were carried out by KPTCL jointly with CTU and CEA and explained various transmission alternatives considered. The presentation and the results are given at Annex-II.
2.2 After discussion, it was agreed that following transmission system would be implemented by KPTCL for evacuation of power from Yermarus TPS(2x800 MW) under Stage-I.
(i) Bellary 400kV Pooling Station near ‘BTPS’. (ii) Gulbarga 400/220 kV substation 7x167 MVA( single phase) or 2x500
MVA. (iii) Yermarus TPS - Gulbarga 400 kV D/C line with quad moose conductor (iv) Establish 400 KV switching station at Chikkanayakanahalli (C.N Halli)
near “Loop in Loop Out” (LILO) point on the Nelamangala – Talaguppa 400kV lines to Hassan.
(v) LILO of both the circuits of Nelamangala – Talaguppa 400kV lines to the proposed pooling station near CN Halli.
(vi) Terminate 400kV D/C line feeding 400/220 KV station at Hassan from Nelamangala – Talaguppa line at CN Halli 400kV pooling station.
(vii) Yermarus TPS - Bellary Pooling Station 400kV D/C line with quad moose conductor
(viii) Bellary Pooling Station - C.N.Hally 400kV D/C line with quad moose conductor
(ix) Bellary Pooling Station - New Madhugiri (near Tumakur) 765/400kV station, 400kV D/C line with quad moose conductor
(x) Bellary TPS – Bellary Pooling Station 400kV D/C line with quad moose conductor
(xi) De-link 400kV S/C line running between RTPS-BTPS-JSW-Guttur with ‘BTPS’ and JSW Bus so as to retain direct connectivity between RTPS and Guttur
(xii) JSW TPS – Bellary Pooling Station 400kV D/C line with quad moose conductor
2.3 It was agreed that KPTCL would take up the item nos. (xi) and (xii) above, only after the rest of the transmission lines and substations in the scope of Stage-I, above have been commissioned. KPTCL said that, for the item no. (xii), they would discuss with M/s JSW to take up this work as dedicated transmission line by the generator, and the same was noted.
6
2.4 All the new substations given above would be designed for fault level of 50kA.
2.5 KPTCL would plan an additional 400kV D/C transmission line from JSW TPS or would configure the JSW-Bellary link in such a way that in case of contingency the LILO of RTPS-Guttur at JSW would be re-established. If there is any constraint/congestion in the system beyond Bellary Pooling Station/or New Madhugiri S/S then the JSW or other generators connected at Bellary P.S. may have to be backed down.
2.6 It was agreed that following transmission system would be implemented by KPTCL under Stage-II matching with the Edlapur TPS(1x800 MW) generation project:
(i) Edlapur TPS - Bellary Pooling Station 400kV D/C line with quad moose conductor
(ii) Edlapur TPS - Yermarus TPS 400kV D/C line with quad moose conductor
(iii) Tumakur (New Madhugiri) - Bastipura (Mysore) 400kV D/C line with quad moose conductor
3.0 The concept on General Network Access (GNA), titled “Ensuring adequacy in the planning & development of Inter-state Transmission System”.
3.1 Director(SP&PA) made a presentation on the concept of GNA, detailing the issues and concerns in the present practice of according connectivity/ LTA with target region / or LTA for capacity less than the installed capacity. Regarding ‘connectivity’, as provided under the regulations, he said that it has to be in accordance with the Section 7 of the Electricity Act 2003 and CEA’s technical standards for connectivity to the grid. The LTA with target region, which was introduced since the States were not firming up their long term power requirements through Case-I biddings, does not ensure building up of adequate transmission system required by the states/region of actual drawal of power. The MTOA and STOA are operated using margins in the existing system and do not mandate creation of additional transmission capacities thus often leading to congestion. He said that GNA provides flexibility to both the generators and the drawing State entities in sale/purchase of electricity under long-term, medium term or short term and ensures availability of adequate ISTS network to meet their requirement up to the GNA quantum. He emphasized the need to declare realistic GNA by the drawing entities and GNA corresponding to full installed capacity of generators. He also highlighted that as under GNA, the total quantum of MW that would share transmission charges would be more as compared to under the existing mechanism, therefore, the rate of transmission charges in terms of Rs/MW/month may be lesser. A copy of the presentation is given at Annex-III.
7
3.2 CE(SLDC), GETCO said that under GNA, the States would be required to assess their drawal requirement 4-5 years in advance. He said that it is not possible to correctly estimate the GNA requirements (injection / and drawal) by the States generally because of uncertainty in assessment of demand, the setting up of state generations, availability of gas, price of gas/fuel and increasing penetration of renewable energy. Further, it is also difficult to assess as to how many open access customers would source their supply from outside the State and therefore, it becomes difficult for the DISCOMs/States to assess accurately their GNA requirement. The open access customers are increasing in Gujarat. Some private DISCOMS are also sourcing cheaper power from outside instead of from the generators within DISCOM/State. Similarly, some of the captive generators are selling outside the state whose requirement cannot be assessed by the State. Under GNA concept, there may be over planning of the ISTS as well as the Intra-State network. However, under GNA the needy States would not be deprived of power because of lack of transmission. GNA would facilitate evacuation of power from merchant capacities and would encourage short-term market. Therefore, before implementing the GNA, likely requirement of transmission augmentation with cost implications may be studied for various load-generation scenarios.
3.2 Chhatisgarh and Tamil Nadu said that they would send their comments, if any, by 02nd January 2014
3.3 MS, WRPC said that the GNA concept may lead to over sizing of the ISTS. There is need for aligning the GNA concept with the PoC mechanism. It would be difficult to predict GNA requirement by States 3-4 years in advance. There is need for change in present regulation (Connectivity LTA, MTOA & STOA, PoC regulation) to overcome shortcomings.
3.4 MS, SRPC agreed with the concept of GNA as it would help in creating adequate transmission capacity in the country. He said that assessment of GNA requirement is dependent on a number of external factors. Therefore, GNA requirement for next five years could be assessed as a rolling Plan. Practicable minor modifications may be accommodated in GNA assessment to take care of uncertainties.
3.5 DGM(CTU), PGCIL opined that, CEA/CTU could assist the States for assessing their GNA requirement for the purpose of transmission system planning. However, it may not be necessary for the States to pay/commit to pay upfront the transmission charges as per their GNA quantum, because any upfront commitment by States may lead to conservative assessment of GNA, which in turn may lead to low transmission development. COO, POSOCO said that it
8
would dilute the concept of GNA as the States have to take the responsibility of assessment of their GNA requirement in a realistic manner.
3.6 Director(GO&Trans), APTRANSCO welcomed the concept of GNA as proposed by CEA. He suggested that the State beneficiaries may be excluded from the requirement of submitting bank guarantees to CTU, as the beneficiaries are functioning under the control of the respective State Governments.
3.7 AGM, NTPC said that CERC’s regulation on the connectivity, had helped the generators, in the past, in fulfilling their requirement for achieving financial closures. He opined that GNA is an ideal concept and would help in planning and development of adequate transmission system both for generators and as well as for the drawing entities.
3.8 Director(Transmission), KSEB welcomed the concept of GNA as it would provide flexibility to any utility to procure power from any generator and vice-versa for the generators. However, the additional expenditure on transmission system, under GNA should not be loaded to the beneficiaries, in case of default by generators. He agreed that the present practice of granting connectivity and allotment of LTA for partial capacity may be reviewed. A payback period for transmission cost recovery i.e. 12 years as proposed under GNA is on lower side. Life of the transmission system is more than that of a generator and therefore currently adopted period of cost recovery may be followed. Grid expansion plans evolved based on GNA should be able to cater to needs of various feasible operating scenarios and should also provide margins to take care of uncertainties in load generation balance. He suggested that along with the proposed GNA philosophy, the cost sharing principle may also be reviewed.
3.9 Karnataka principally agreed with the concept of GNA for development of Inter State transmission system.
3.10 Chairperson, CEA asked all the participants to send their comments latest by 2nd January and asked SRPC and WRPC to facilitate in expediting comments of the States who were not present in the meeting.
4.0 Meeting ended with vote of thanks.

General Network Access(GNA)
Central Electricity AuthorityDecember 2013
Ensuring adequacy in the planning and development of Inter State Transmission System
Annex-III
CEA 2
Existing Mechanism for Transmission Access
Connectivity for Generator with ISTS:No charges payable & no commitment to provide
access – no transmission strengthening
LTA (Point to Point): - Adequate transmission system get planned and implemented.
LTA (Target Region) – part transmission system gets planned, may be insufficient
MTOA/STOA: - no transmission strengthening, uses margins in existing transmission system

CEA 4
Congestion – due to inadequate transmission system planned and increasing STOA/MTOA transactions (from 8 BU in 2007 to 50 BU in 2013)
For LTA (target region) :Burden of additional PoC charges (for target as well as actual drawal point)
While availing MTOA/ STOA, no preference over those having mere connectivity.
Disproportionate payment of PoC charges –disadvantage to Generators /Utilities who follow long term PPA vis-à-vis those who over-inject/ over-draw than their LTA
Concerns in existing approach
CEA 5
% Drawal above LTA quantum
CEA 6
System to be planned based on Generator/ Demand quantum and their location without knowing the contracted source of purchase/ sale
The generator and the States/Consumer could be given general network access (GNA) to ISTS for the agreed quantum of power (MW)
For grant of GNAGenerator will not have to specify drawal pointsDrawee entity will not have to specify injection points
Generators mandated to take GNA corresponding to their ex-bus capacity (other than captive)
A GNA agreement with generators/drawing entity could become the driver for investment in transmission - GNA to be assessed at least with 4-5 years in advance
New approach - General Network Access
CEA 7
Cont..
Existing transmission service – ‘Connectivity (as per the CERC)’ and LTA (target regions) for IPPs may be discontinued in view of GNA
Any power transfer beyond the GNA capacity may be entertained only through STOA service at a premium rate (say 100%)
The concept of PoC charges and GNA are not path specific or point to point specific. Accordingly, in GNA transmission charges would determined by the GNA quantum and PoC rate for that point
7
New approach - General Network Access
CEA 8
For GeneratorsGenerators to get all India access with flexibility to change point of drawalGenerators not be liable to pay for notional point of drawal chargesGenerators will not have to declare target beneficiaries
For Drawing EntitiesReliable access for short term and medium term market. This will be a great comfort to OA consumers as well as DISCOMs.States empowered to determine their GNA requirement and get the ISTS built for it.DISCOMs will be able buy cheap power with certainty through the PX at where the competition is intense - will benefit consumers
Benefits under GNA
CEA 9
The GNA may be for a period of 12 years( to ensure recovery of investment in transmission )
For scheduling under GNA, it is proposed that - the LTA (P-to-P) can be for a minimum period of 5 yearsMTOA for one year fixed tenure, with window opening twice a year, The STOA for period up to 1 monthThe difference between LTA/ MTA/ STOA users may be in the priority of scheduling
Tenures under GNA mechanism
