of SRPC to be held at SRPC, Bengaluru on 20.06.2019.

1. Introduction

2. Confirmation of the Minutes of 40thCommercial Committee meeting Minutes of the 40thMeeting of the Commercial Sub-Committee of SRPC held on

25thFebruary 2019 were issued vide letter No. SRPC/SE-I/40CC/2019/1434-67dated

19thMarch 2019.Amendment to the minutes (Item No. 6.1.7) was issued vide letter No.

SRPC/SE-I/40 CC/2019/1434-67 dated 17.5.2019.

The Minutes of the meeting, incorporating the amendment issued, may please be confirmed.

3. Audit of SR Deviation& Reactive Energy ChargePool Accounts In line with Para15 of Annexure-I to the CERC (IEGC) Regulations, 2010

(Complementary Commercial Mechanism), RLDC shall table the complete statement of

the Regional UI account and the Regional Reactive Energy pool account in the RPC’s

Commercial Committee Meeting on a quarterly basis, for audit by the latter.

SRLDC vide letter SRLDC/MO/CCM dated 17-05-2019 (ANNEXUREA) have

furnished details of payment and disbursement of weekly Deviation and Reactive

Energy charges for the period from 14.01.2019 to 21.04.2019.

The Accounts may be audited.

4. Items proposed by SRLDC SRLDC vide letter dated 17.05.2019 (refer ANNEXURE A) have proposed the

following items for discussion:

(i). Audit of SR DSM& Reactive energy Accounts.

(ii). Reconciliation of DSM, RRAS, Reactive and Congestion charges.

(iii). Status of outstanding charges to the pool accounts.

(iv). Reconciliation of Short Term Open Access (STOA) disbursements.


5. SEM issue at Ananthapuramu(NP KUNTA) ULTRA MEGA SOLAR PARK It was noted during the 39th and 40thCCM that SEM reading i.r.onight drawal values of

all ACME SPDs were mostly zero.

In the 40th CCM SE (O), SRPC requested SR-I, PGCIL to take up testing and

calibration of the above SEMs (on payment basis) so that the problem is fixed and

APSPCL was requested to coordinate for the calibration.

SR-I, PGCIL agreed to take up the calibration works, however, they would discuss

thematter internally with the officials concerned and revert.

It was also suggested to swap the non-recording SEMs with the SEMs

presentlyrecording drawal,so as to ascertain the reason of malfunction.APSPCL and

ACME SPDs were requested to mitigate the problem so that preciseenergy accounting

of all SPDs of the park could be carried out.

In spite of the above, the SEM values continued to have the same discrepancy and hence

the average drawals are being computed to assign drawal values to these SPDs to assess

deviation.

APSPCL may clarify. It is also requested that a representative from ACME may attend the

meeting to present the factual position.

6. NNTPP power to be scheduled to Tamil Nadu through ISTS In the 40th CCM,SRPC Secretariat presented the computation of percentage of NNTPP

power to be scheduled to Tamil Nadu through ISTS, for which losses are applicable, out

of total share of allocation and informed that in case of any major changes in the

allocation, the scheduling percentages could be recomputed then.

Subsequently, it was noted that 53 MW of unallocated power from Neyveli New

Thermal Power Station (NNTPS) has been allocated by MoP to U.T of Puducherry over

and above the firm allocation of 4.24 MW.Accordingly, the revised computation of

percentage of NNTPP power to be scheduled to Tamil Nadu through ISTS is given

12. Compensation Computation for SCED

• Security Constrained Economic Despatch (SCED) for Inter State Generating Stations

pan India wasoperationalized from 1stApril, 2019.

• The detailed procedure on SCED for ISGS Pan-India defines the role of RPC to issue

Weekly SCED accounts based on the data provided by RLDCs and monthly

“Statement of Compensation due to Part Load Operation on Account of SCED”

separately for all SCED generators.


• In this regard, Compensation due to Part Load Operation on Account of SCED as

well as beneficiaries are defined as shown below:

• Compensation for degradation of Heat Rate (SHR) and Auxiliary

EnergyConsumption (AEC) Computation remain unaltered as defined in the

approved detailedprocedure issued vide the CERC Order dated 5th May, 2017.

It is mentioned in the Tariff Regulation, 2019-2024, that

CVPF = Weighted Average GrossCalorific value of coal as received, in

Kcal/Kg for coal based stationsless85 Kcal/Kg on account of variation during

storage at generating station.

All concernedare requested to furnish CVPF value aftersubtractingthe

quantum of 85 kCal/kg for Coal based Stations.

The following procedure would be adopted for Computation of compensation:

• For computation of compensation SCED will be considered as an entity along with

the Beneficiaries.

• Final Compensation payable by kth beneficiary and SCED for the calculation period

ending nth month is as below:

No compensation shall be payable by a beneficiaries if it has requisitioned at

least 85% of its entitlement during the calculation period.

No compensation shall be payable to SCED Generatorif it hasnet increment

in schedule during the calculation period. If the SCED Generator has net

decrement schedule, then the net decrement schedule shall be considered for

sharing of compensation by SCED.

The compensation amongst allbeneficiaries and SCED shall be shared in the

ratio of un-requisitioned energy below 85% of their entitlement for

beneficiary and net decrement schedule for SCED, i.e., compensation payable

by kth beneficiary and SCED for the calculation period ending on nth month

FCBkn = Compn(F) ∗UEkn

∑UEkn

Where UEkn is un-requisitioned energy of kthbeneficiary below 85% of its

entitlement and net decrement schedule for SCED during the calculation

period ending nth month.

• RPCs issues monthly "Statement of Compensation due to PartLoad Operation on

Account of SCED” (as per Format SCED4 specified in the detailed procedure). An

illustrative example is given below:


Compensation Calculated for the ISGS Station =Rs.X.

If there are 4 beneficiaries for the ISGS Station, and the ratio of Un-

requisitioned energy of beneficiaryand SCED below 85% of its

entitlement from ISGSStationsare as shown below:

• This will be carried out on Cumulative basis in line with the Compensation

Procedure.

Placed for the deliberation/concurrence of the sub-committee.

13. Compensation Calculation for Secondary Fuel Oil consumption

• The approved detailed procedure for taking unit(s) under Reserve Shut Down and

Mechanism for Compensation for Degradation of Heat Rate, Aux Compensation and

Secondary Fuel Consumption, due to Part Load Operation and Multiple Start/Stop of

Units, stipulates that Calculation of Compensation for degradation of Secondary Fuel

Oil consumption for the year shall be done iftotal number of start-ups exceed 7 x no.

of units in the generating station. Compensation for degradation of Secondary Fuel

Oil Consumption (in terms of KL of Secondary Oil)shall be calculatedby multiplying

number of start-ups exceeding 7 per unit,which are solely attributable to reserve shut-

downs, with the appropriate value of additional secondary oil consumption specified

in Regulation and shall be restricted such that Oil Consumption based on Norms plus

Compensation calculated as above does not exceed actual Secondary Fuel oil

consumption for the year.

• For example, if the station consists of 3 Units and there are total 28 outages

(Forced/Planned/RSD) for a year, out of which 9 are attributable to RSD, then


Compensation shall be calculated for number of stat-ups exceeding 7 X 3 =21, which

are solely attributable to reserve shut-downs.,i.e., 28-21=7 outages would be

considered for compensation of degradation of SFC.

• Among the above reserve shut-downs, if there are 4 Cold, 3Warm and 2Hot RSD

category, then oil compensationwill be computed as(COLD*4+ WARM*3+

HOT*2)*7/Total start-ups attributable RSD (9); i.e. for example, compensation

calculated be 770 KL.

• Compensation payable to CGS/ISGS shall be restricted such that OilConsumption

based on Norms plus Compensation calculated above does not exceed actual

Secondary Fuel oil consumption for the year.

• Each start-up due to reserve shutdown shall be attributed to the beneficiaries, who had

requisitioned below 55% of their entitlement.SRLDC is requested to furnish the relevant

requisition data of the beneficiariespertaining to Generating Station(s) for the

period,blocks, based on which decision to take generator(s) under RSD is taken.

14. NLCIL and NTPL Agenda

• NLC India Ltd.,vide letter dated 18.05.2019 (ANNEXUREG), forwarded the

following agenda for discussion in the meeting:

• The Power Bill Dues from DISCOMs to NLCIL & NTPL as on 15-05-2019

In spite of regular letters to the senior officials of the DISCOMs and frequent

visits to the DISCOM Offices by NLCIL' s officials to pursue the payment of

huge dues from them, payments commensurate with the outstanding dues are

not being made by DISCOMs which results in the accumulation of dues. The

huge outstanding makes it difficult for NLCIL in the financial management of

ongoing projects and for NTPL in making payments for coal purchases.

• M/s. KKNPP states that in spite of assurance given in the Commercial meetings of

SRPC held, the outstanding dues have not been cleared as on date. KKNPP also

requests that SEB's shall commit exact date for payment of such long outstanding

dues. Further, non-receipt of energy dues from SEB's is hampering KKNPP day to

day activities along with working capital management and are unable to clear off

liabilities in timely manner.

• Additionally, M/s. KKNPP vide the letter dated 21-05-2019 (ANNEXURE J)had

also intimated to Additional Chief Secretary to Government of Karnataka regarding

the non-payment of Energy dues and LC related non-compliance by M/s HESCOM,

M/s CESCORP and M/s GESCOM.

• Subsequently, M/s. KKNPP vide the letters dated 23-05-2019 (ANNEXURE K)

had again requested TANGEDCO, HESCOM, GESCOM and CESCOM to clear the

Overdue Energy bills and DPC as early as possible.


The agenda point would be discussed in the meeting and the above

beneficiaries are requested to present reply.

16. NTECL agenda Points

• NTECLvide their letter dated07-05-2019 and29-05-2019 (ANNEXURE L) had

intimated regarding the outstanding payment against energy billsraised on the

beneficiaries such asAPPCC,HESCOM,CESCORP,GESCOM, TSPCC and

TANGEDCO.

• In this regard, it may be mentioned that in addition to fund requirements for other

operational needs, NTECL also needs to make advance payment to the coal

companies against the coal supplies. In case regulation of coal supplies takes place,

it will result in reduction in DC from NTECL Vallur Station, which in turn will

cause reduction in Power availability for the beneficiaries.

• Moreover, with the introduction of SCED, NTECL needs to make payment to

POSOCO SCED pool account to the tune of 10-15 Crores every week and due to

huge outstanding from beneficiaries, release of payment to SCED pool account from

NTECL is also adversely affected. It is pertinent to mention that in the event of

default in payment to SCED pool account; it shall attract huge interest liability.

The issue would be discussed in the meeting.

All the Constituentsconcerned are requested to update the status of

payment.

17. Transmission Charges Pertaining to Kudgi STPS 1. Regarding Additional LTA Quantum

• The matter was discussed in the earlier CCM meeting and in 34th SRPC meeting

held on 11-08-2018, all beneficiaries had concluded that the additional quantum

needs to be relinquished immediately to avoid future liabilities.

• In this regard, CTU clarified that till the quantum is relinquished or some Order is

received from CERC, full LTA quantum would continue to be billed.

• NTPC vide their letter dated 26-03-2019 had requested CTU for the revision of LTA

granted to NTPC for Kudgi TPS from 2392.49 MW to 2250 MW on account of

auxiliary consumption and overload capacity.


• Subsequently, CTU letter dated 16-05-2019 had intimated that 142.49 MW is

relinquished from 2392.49 MW to 2250 MW on account of auxiliary consumption

and overload capacity. It was requested to facilitate the signing of necessary

amendments to agreements as per provisions of CERC Regulations 2009 as

amended from time to time.

• In this regard, NTPC vide the letter dated 22-05-2019 (ANNEXURE M) requested

all beneficiaries to take up with CTU for signing of the requisite agreements to make

the revision of LTA effective.

NTPC/Constituents may furnish the update.

2. Regarding CERC Order No. 261/MP/2017 dated 06-11-2018 • CERC vide order dated 06.11.2018 had asserted and directed the following:

a) The liability to pay charges towards Long term Access under Central Electricity

Regulatory Commission (Sharing of inter-State Transmission charges and losses), Regulations, 2010 as amended from time to time shall be that of beneficiaries in view of Agreements entered into by them.

b) The LTA needs to be operationalized from the date of declaration of COD of the transmission system irrespective of the CoD of the generator.

c) Annual transmission charges of the associated transmission system (i.e. in this case -Kudgi-Narendra, Narendra-Madhugiri and MadhugiriBidadi and associated bays/ substation) as determined or adopted by the Commission shall be considered in PoC mechanism corresponding only to the units declared under commercial operation and the balance transmission charges shall be recovered from NTPC till the respective COD of remaining units.

• SRPC has already revised RTA on 22.11.2018 corresponding to transmission charges

recoverable from NTPC till COD of the respective units, as per data furnished by

CTU/NLDC.

• In this regard, SRPC, vide letter dated 06-02-2019, had requested data for

compliance of the CERC directions at Para 44(a), (b) and part of (c) of the Order and

also to furnish revised Slab rates and LTA quantum for the applicable period.

• Further, KSEBL, vide letter dated 20.12.2018, referring to CERC Order dated

06.11.2018 in Petition No. 261/MP/2017 had pointed out the following:


Charges recoverable (Rs. 304.10 Cr) from NTPC for the periods August 2016

to September 2018 are to be reimbursed to the beneficiaries who had paid

this amount originally.

PoC slab excluding rates revision for the period August 2016 to September

2018 excluding the charges of Kudgi ATS needs to be carried by NLDC. The

benefit of this revision needs to be passed on to the SR beneficiaries as they

had borne these charges.

SOUTHERN REGIONAL POWER COMMITTEE

BENGALURU

Additional Agenda for the 41st Meeting of Commercial Sub

Committee of SRPC to be held at SRPC, Bengaluru on

20.06.2019. The following agenda items would be discussed in the meeting:

1. AP Agenda Points

AP vide mail dated 03.06.2019 (ANNEXURE Q) had requested to consider plant

wise dispatch instead of Unit wise dispatch from NTPC Kudgi (3×800 MW) power.

Due to Frequent & prolonged RSDs of the Plant, AP had to confront hurdles to meet

the daily AP Grid Demand.

It has been observed that, while operating, scheduling / dispatching of the Capacity /

Energy generated from Kudgi plant by SRLDC, allocation has been reckoned on Unit

basis rather than on Plant basis. That means unit wise declared capacity is being

allocated to all beneficiaries on the basis of their entitlement. For instance, Karnataka

which is having an allocation of around 54% in the plant, during light load (Grid

Demand) condition prevailing in the State, backs down the generation from Kudgi

Station and thus the unit is forced into Reserve Shut Down mode, since, technical

minimum condition is not fulfilled. This deprives the other beneficiaries of their share

of power.

In such circumstances the States with lesser allocation are unduly got affected due to

Reserve Shut Down instructions (RSD) issued by the major stakeholders depending

on the Load Generation Balance in their grid.

The agenda item would be discussed in the CCM.

2. TANGEDCO Agenda Points

TANGEDCO had requested to include the following agenda points (vide letter dated

06.06.2019, ANNEXURE R) as shown below:

I. Issues related to implementation of the Hon’ble CERC’s order dated

08.03.2019 in Petition No. 92/MP/2015.

a. Based on the above referred CERC Order, CTU has been directed to

calculate the stranded capacity and the compensation (relinquishment

charges) payable by each relinquishing long term customer as per

methodology within one month of date of issue of the Order and

publish the same on its website. CTU has not yet published the same.

b. Further, it was also stated that M/s NLDC, the Implementing Agency

has to ensure that no LTA quantum of generators is socialized in the

PoC pool for the sake of relieving the generators.

II. Delay in Commissioning of the NNTPP Plant

III. Prolonged rerated capacity declaration and inefficient plant management of

NLC TPS-II Expansion

IV. Delay in commissioning of Kalpakkam PFBR by Bhavini.

CTU/NLDC may update on this agenda item.

The matter may be further deliberated in the meeting.

3. Inclusion of all Bilateral Billing including RE Generators

As per CERC Order in Petition No.155/MP/2016 dated 04-01-2017, NLDC/CTU has

been requested to furnish all bilateral billing; including RE Generators to RPC along

with the submission of monthly LTA/MTOA details.

Further, it is also requested that the LTA operationalizion details corresponding to

Renewable Generators may be furnished along with the above said monthly details.

CTU/NLDC may elucidate.

APPCC---- Agenda Point for the 41st Commercial Sub-Committee Meeting /SRPC Sub:- Considering Plant wise dispatch instead of Unit wise dispatch from NTPC Kudgi (3×800 MW) power – Frequent & prolonged RSDs to the Plant-hurdles to meet daily Grid Demand by AP

***************

a) The NTPC has developed Kudgi Super Thermal Power Station -Stage 1 with 3×800 MW

configuration in the state of Karnataka. AP DISCOMs in the erstwhile combined AP

State have entered into PPA with M/s NTPC Limited for purchase of power from this

plant on 23/09/2010, subject to the allocation as decided by Govt. of India.

b) Power Purchase Agreement has been entered into by the beneficiary States/Entities for

the entire capacity (3X800=2400 MW) of the Stage-I project.

c) As per the PPA Clause 2.1.1. “Allocation of Capacity from the Station to the State of

Andhra Pradesh shall be as decided by GoI, based on the existing GoI policy.

d) As per Clause 2.2.3, “the allocation made from the Station by GoI or any other

competent authority in favour of APPEDCL shall be the contracted capacity....”

e) The state of Karnataka is having a major share of around 54% in the project and

bifurcated Andhra Pradesh state has a share of 16.03% as per the latest allocation of

Ministry of Power Govt of India. The present share of Andhra Pradesh is 384.72 MW

from NTPC (Kudgi) power plant as per the following breakup.

Firm Share 215.04MW

Bundled power against

NVVNL coal power

14.4MW

Bundled power against

National Solar Mission

phase-II Batch-II Tranch-I

155.28MW

Total 384.72MW.

f) As per Clause 4.1 of the PPA with regard to Scheduling, ..... NTPC shall make

declaration of the capacity at the busbars of the Station after taking into account the

capability of the station to deliver EX-Bus, which shall be considered while calculating

declared capacity.

g) It is observed that, while operating, scheduling / dispatching of the Capacity / Energy

generated from Kudgi plant by SRLDC, allocation has been reckoned on Unit basis

khan

Annexure Q (Page1/3)

rather than on Plant basis. That means unit wise declared capacity is being allocated to

all beneficiaries on the basis of their entitlement. Consequent to the implementation of

RSD procedures, in the instant case Karnataka which is having an allocation of around

54% in the plant, and any light load (Grid Demand) condition prevailing in Karnataka

forces that state to back down the generation from Kudgi Station, thus depriving the

other beneficiaries of their share of power since, technical minimum condition is not

fulfilled. Thus the unit is forced into Reserve Shut Down mode.

h) Even though the PPA has been entered into on Plant basis and Fixed Cost is payable

for the entire project as per the monthly REA, the entitlement of the target generation

schedules on Unit basis is hampering the prospects of other states. .

i) In these kind of circumstances the States with lesser allocation are unduly got affected

due to Reserve Shut Down instructions (RSD) issued by the major stakeholders

depending on the Load Generation Balance in their native States. The technical

minimum of operation of each unit is 55%. The major stakeholder has the

allocation almost equivalent to the technical minimum. Once the load in the State which

is having major share, drops below a certain level and Merit order stack doesn't support

the dispatch from Kudgi, the plant is forced to RSD state, there by depriving other

beneficiaries the much needed power, even though the States are feeling under power

shortages.

j) The monthly “Regional Energy Account (REA)” is settled on the basis of entire plant and

not based on individual unit. The fixed costs are also payable based on the overall plant

availability during the month and not segregated Unit wise.

k) During this calendar year 2019 so far, the Kudgi plant was under RSD for several days.

AP has to purchase power from costly sources to substitute the expected allocation from

Kudgi plant, and thus the APDISCOMs have incurred huge mounts. During the period of

1st January to June15th, the Load on the AP system is more and has to be supported by

matching generation from all entitled sources. Had there been generation from Kudgi

station as per the PPA entitlement, the state could have reduced exposure to the open

market.

l) AP is also a RE rich State having combined installed capacity of Wind & Solar at around

7000 MW and further in the interests of grid security and addressing intermittency of RE

generation, hot reserve in terms of base thermal generation is essential in Grid

operation.

m) Commercial Sub-Committee is requested to deliberate on the issue, and resolve to

recommend to NTPC & SRLDC to carry out Plant wise dispatch instead of Unit wise

dispatch.
