B CCM agenda items

Item Issuance of provisional REA data issued by WRPC every month- correction

No.1 thereof

CSPTCL vide letter dated 12.07.19 informed that- (i) As discussed in the meeting for freezing of REA data for the month of

January to March -17 held on 27th of April 2017, the URS data in respect of CSEB showing in implemented schedule in WRLDC website

was not matching with REA data provided by WRPC for the month of Dec-2016 to Mar-2017.

(ii) Further in the 74th CCM (item 14 in MoM) pertaining to CSEB Schedule in Kahalgaon super thermal power stations (ER) (K-II) for the period of Aug-2016 to Oct-2016 and issues in past REAs of Aug & Oct-

15, Jan-16, May-16 and Sept-17 were discussed and WRLDC agreed to send the revised data to WRPC.

CSPTCL requested to resolve this long pending issue in REA.

Committee may like to discuss.

Item No.2

Issuance of provisional REA data pertaining to transaction between

Kishanganga Hydel Plant to CSEB_Beneficiary

CSPTCL vide letter dated 12.07.19 informed that-

Scheduling of Kishanganga Hydel Plant was started from 10/06/2018. Difference in data of transaction between Kishanganga Hydel Plant and

CSEB Beneficiary was observed in REA issued by WRPC for the month of June-18, July-18, Sept-18 and Nov-18 for which letters were sent to WRLDC.

For the above issue, CSPTCL engineer visited WRLDC, Mumbai on 26th Dec. 2018. As per discussion there, WRLDC required the day wise mismatch in the schedule of KISHANGANGA Hydel Plant to CSEB

Beneficiary for the month of June, July, September and November 2018, to accurately find monthly mismatch which was sent to WRLDC

vide letter dt.28/12/2018. The issue of mismatch has not been resolved till date. Further the schedule of Kishanganga Hydel Plant to CSEB Beneficiary

may also be included in the REA issued by WRPC.


Item No.3

Issuance of provisional REA data pertaining to transaction between Mouda,

Solapur and NSPCL to CSEB_Beneficiary

CSPTCL vide letter dated 12.07.19 informed that- Difference in data of transaction between Mouda, Solapur and NSPCL to

CSEB_ Beneficiary was observed in REA issued by WRPC for the month

of May-2019 and transaction between Mouda and NSPCL to CSEB_ Beneficiary for month of June-2019 also it was observed that the URS

data showing in REA of month MAY & JUNE-19 is not matching with the URS showing in WRLDC Website for which letters were sent to WRLDC & WRPC.

CSPTCL requested to revise the REAs.


Item no 4.1

Change in RSD procedure for ISGS to get schedule for state having less

share

CSPTCL vide letter dated 23.10.19 informed that:

The share of CG state in ISGS station of WR is in the range of 6 to 12% only. In case of RSD of any of the NTPC generating station, the

state with smaller percentage of share are always on losing side because of the surrender/Re-allocation of share by states having larger share.

During the month of July-19 August-19 and September-19, CG state could not get it share from Mouda-II Solapur & Gadarwara station despite requirement due to surrender by states having larger share and

has to arrange power from other sources at a short notice and high cost.

To safeguard the interest of all small states, there should be an addition to RSD condition that is “if a state is helping any thermal station to be

on bar by scheduling over and above its share in that station for meeting technical minimum requirement, then it should continue to get the additional quantum of schedule at least for next 72 hours of

scheduling and the original beneficiary shall have right for re-allocation to the balance quantum only.

This will help in not only keeping the ISGS on bar but will also help states with smaller share in meeting their requirement through ISGS

stations.


Item

No.4.2 Working Arrangement for commercial settlement of transfer of URS from

one constituent to another constituent to meet the technical minimum

requirement of ISGS

SLDC Gujrat vide letter dated 24.10.20 (copy enclosed at Annex 4.1) informed that:

SLDC Gujarat has already raised the concerns in the matter. In many forums/meetings, it is decided to ensure injection schedule of the

generating stations at least up to the technical minimum level. Hence, ideally every constituent has to ensure its minimum requisition

according to its share in the generating station X technical minimum of the generating station (of „on bar‟ machines). However, in case of requirement of other beneficiaries in the same generating station for

more than its technical minimum share, remaining beneficiary(ies) can requisite lower than its technical minimum share accordingly.

Further, due to any of the reasons, if it is not possible for any constituent to requisite up to the technical minimum and other

beneficiary (ies) is able to take/accommodate that portion in their drawl schedule to support the grid and to ensure technical minimum requirement of the generator then such quantum of URS is to be

considered in a different way than the regular/normal (on need basis) transfer of URS.

As per the existing agreed mechanism, constitutes availing URS should pay fixed and variable cost of that quantum of URS. However, in case of

transfer of URS to support the technical minimum requirement of the particular generator, it is proposed that constitutes (availing URS to support the technical minimum) should only pay variable charges

for the support quantum. The liability of fixed charges will remain with original beneficiary (ies). Transfer of URS with

variable cost only will help to accommodate ISGS in the State merit order dispatch mechanism. This is a WIN-WIN situation for all the entities.

The similar kind of mechanism can also be introduced for transfer of

URS above the technical minimum of the ISGS.

The abstract of record notes of the 34th WRPC meeting in ITEM No 35 is reproduced hereunder:

Quote

After the discussion, TCC agreed on the following: · All members agreed to the proposal of MP wherein the URS availing beneficiary shall pay 50% capacity charges and

remaining 50% shall be borne by MP themselves. · The proposed above mechanism is valid up to 31.03.2018.

· WRPC shall provide the URS quantum availed in its REA, whereas the adjustments made for the capacity charges shall be done by NTPC.

WRPC discussion:

General Manager, GUVNL stated that GUVNL through letter has conveyed to WRPC that URS share of GUVNL can be availed by any

other state utility without paying capacity charges while GUVNL reserves right to recall the power after 4th time block. In case, the other

state beneficiary desires GUVNL‟s URS on committed basis for a day, the beneficiary shall pay 50% of capacity charges to GUVNL. The energy charges and other cost will be settled with NTPC as is being presently

done

Unquote It will help in better utilization of cheaper resources (it is observed that

some States are facing problem of coal shortage and still don‟t be able to schedule URS from other cheaper ISGS due to liability of both variable and fixed cost), higher PLF of ISGS and most of the time ISGS will get

the schedule more than technical minimum. Frequent start-stop of the ISGS can also be avoided


Item

No 4.3 Scheduling of beneficiaries who do not get power due to technical difficulties

DD vide letter dated 06.11.19 (copy enclosed at Annex 4.3) informed the following –

U.T. of Daman & Diu has been allocated power from various generating stations of NTPC and NPC both during peak and off peak hours. UT of

DD do not have their own generating stations and as such our entire load requirement by and large are mostly met from the allocations of power made from central sector generating stations.

NTPC are regularly submit 15 min time block Declared Capacity of their stations to WRLDC and based on the DC declared and scheduled power

sought by various beneficiaries of these stations commensurate to their entitlements, WRLDC issues final schedules to these NTPC Stations.

U.T. of Daman & Diu, based on the DC declared and the entitlement of allocated power, submit requirement for scheduling of power from

Gadarwara, Solapur and Mouda Stations of NT PC. However, nil generation schedule is issued to the generating units of these station as

other beneficiaries of WR has not asked to schedule power from these unit and the total schedule is below technical minimum.

In the above process U.T. of DD is in need of power and right to schedule as per allocation, but is deprived. So on one hand no power is

schedule despite DC declared by NTPC and on the other hand DD end up in paying capacity charges.

DD requested to look into the matter and examine the possibility of scheduling the power from other running units of NTPC in the above

prevailing situations.

Item No.5

Payment of outstanding charges for wheeling of power through OPTCL

system via Budhipadar and other applicable charges.

MSEDCL vide letter no. MSEDCL/CE/PP/82nd CCM/agenda points/020663 dated 24.07.19 informed the following:

MSEDCL vide email dated 24/10/2018 has informed WRPC that MSEDCL has to recover provisional amount of Rs. 1,25,19,751/- for the

wheeling charges as paid to OPTCL for the period July 2011 to March 2012. Though, M/s OPTCL has claimed the same through PoC mechanism, it used to raise invoices @17.5 Ps per unit to MSEDCL.

MSEDCL has paid the subjected bills as per the prevailing rate of @10 Ps per unit for April 2011 to March 2012.

Further, ERPC has to prepare STOA credit receivable to Maharashtra pertaining to period FY 2004 to FY 2011 and inform the same. Gujarat and MP have also raised the issue of outstanding charges as

receivable to them from M/s OPTCL in CCM forum. Accordingly, this issue was discussed in 78th and 79th Commercial committee meetings. During 79th CCM, Committee had decided to convene the meeting

between beneficiaries WRPC, SRPC, OPTCL and ERPC at the earliest. But no such meeting has been held so far. The representative of M/s

OPTCL/ ERPC may be requested to attend the meeting to resolve the issue else separate meeting between beneficiaries WRPC, SRPC, OPTCL and ERPC

may be arranged as decided in 79th CCM meeting.

Item No.9

Installation of new Interface Energy meters, AMR system and meter data processing system

Background:

As per the minutes of 36th WRPC, POWERGRID has to replace existing meters by New Interface Energy Meters, AMR system and meter data processing system having specifications as approved in 34th WRPC

meeting and recover the cost from the entities on one time basis. POWERGRID had invited bids for the work of “Implementation of 5-

minute metering with New Interface Energy Meter (IEM), Automated Meter Reading (AMR) System and Meter Data Processing (MDP) System

in POWERGRID Western Region” vide NIT dtd. 27.11.2018. Some vendors had sought clarifications in the pre-bid meeting.

37th WRPC Meeting (18th December, 2018), A group, with members from WRLDC, GETCO, MPPTCL, MSETCL,

POWERGRID, Chhattisgarh and Adani Power was formed to address the pre-bid queries raised by the vendors. The group met on 24.12.18 and deliberated the points raised by the vendor. The minutes of the meeting,

after approval of TCC Chairman forwarded to POWERGRID by WRPC. Further POWERGRID wrote to WRPC about vendors seeking some

modification in the payment terms/penalty clause. The same was forwarded by WRPC to all subcommittee members. The consolidated

response was emailed by WRPC to POWERGRID. Thereafter POWERGRID further sought the opinion of WRPC regarding

opening of bids in the event of poor participation. Opinion of WRPC members was forwarded to POWERGID by MS, WRPC on 12.04.2019.

38th WRPC Meeting (27/28th June, 2019):

PGCIL informed the following

Only one supplier quoted and bid was opened on 24.06.2019.

Supplier quoted three times the estimated cost.

Evaluation committee will evaluate the bid and it will take 21 days to evaluate the price bid.

The report of the evaluation committee will be sent to WRPC members.

Within 21 days or before, PGCIL would give the update. Further follow-up.

PGCIL vide letter dated 16.08.2019 informed the following: Price Bid of single bidder M/s Secure opened on 24.06.2019. The price

quoted is abnormally higher side than our estimate. On detailed Analysis we have found following reasons- 1)Being first of its kind, there was no bench marking/historical data for

cost estimate 2)Implicit BOQ i.e. requirement of various hardware and software for control center and FO cables for system integration at SS level

After internal deliberations and consultation with other utilities, the

BOQ is being finalized. With the finalization of Bill of quantities and market survey, cost estimate is being worked out based on TS issued along-with various amendment by WRPC. After approval of revised Cost

estimate retendering process shall be done on top priority. WRLDC vide letter no. WRLDC/MO/1551/2019 dated 30.10.19

informed the following – a. WRLDC had forwarded the estimated future SEM requirement

to WR-1 and WR-2 vide email dtd. 26.11.18 and 24.09.19. b. It is understood that MSETCL has placed award for new interface

meters, AMR and MDP system. The technical specifications were

based on the approved WRPC specifications. It is understood that several vendors participated. POWERGRID may like to benefit

from the MSETCL experience.

POWERGRID may update the present status.


Item No 10

Non-availability of Delay Payment Charges towards Payment of DSM Bill for 31.12.2018

MSLDC vide letter dated 27.08.2019 informed that: MSLDC had received DSM bill wherein bill period mentioned was

31.12.2018 to 06.01.2019. It was evident from the covering letter that the payment mentioned was for the week 31.12.2018 to 06.01.2019

amounting to Rs 277491/- & it was duly signed. This Office has paid Rs 277491/- vide Cheque No. 097/42 dtd 07.02.2019 within the timelines

of DSM. Further, MSLDC was in receipt of revised bill with period mentioned

01.01.2019 to 20.01.2019 amounting to Rs 30606903/- . However, considering the weekly pattern of bills issued by WRPC, this office had inadvertently deducted the charges i.e. Rs 277491/-. For 31.12.2018

from the said bill. The payment was done by this office for Rs 30329412/- vide Cheque No. 097755 dtd 27.02.2019, i.e. with

deduction of charges for 31.12.2018. After scrutinizing, it was found that the amount Rs 277491/- was only for 31.12.2018. Thus, the said amount was immediately paid through

Cheque No. 109829 dtd 15.07.2019. MSLDC has never defaulted payment against the timelines of DSM bills

and therefore, DPC may not be charged for the respective period ,i.e. 31.12.2018 as it is inadvertent error on both sides. In view of the above, DPC should not be levied on the amount Rs 277491/-.


Item No 11

Submission of statement of Regulatory account before RPC Commercial Committee

As per Para 15 complementary commercial mechanism (Annexure-I) of IEGC (Amendment-1) which is reproduced here:

Quote “The RLDC shall place the complete statement of regional UI account,

the Regional Reactive energy pool account and Congestion Charge account before the RPC‟s commercial committee meeting on a quarterly basis for audit.”

Unquote

WRLDC to submit all related data of above regulatory accounts (DSM, REC, RRAS etc.) to CCM on quarterly basis.


Item No 12

Transmission Charges payable by RGPPL to MSETCL

Ministry of Power has allocated 540MW to Indian Railways (out of Maharashtra Share) in Ratnagiri Gas and Power Private Limited for five

years since 01.04.2017. Scheduling of this 540 MW allocation (210 MW-Central Railways, 90 MW -Western Railways, 85 MW-West Central Railways, 70 MW South Eastern Railways, 50 MW North Central

Railways and 35 MW South Western Railways) is being done by WRLDC

in line with WRPC Orders issued in this regard. Indian Railways, 'based on the PPA signed with RGPPL against

allocation as above, entered into LTOA with MSETCL for use of their intervening transmission system to connect to nearest CTU system to wheel their share to destination states. The power from RGPPL is

evacuated using 400kV STU lines in Maharashtra namely Dabhol- Nagothane and Dabhol- Koyna lines which were constructed more than

20 years back. Nearest CTU connectivity is at Padghe. RGPPL share to DD & DNH is also wheeled using these lines as per study conducted by WRPC in FY 2010-11. Transmission charges applicable to DD & DNH

were approved in 15th meeting of WRPC/TCC using contract path method.

As per PPA transmission charges paid by Railways are recovered from RGPPL bills as the PPA provides for composite rate of 5.50/Kwh upto Railway Traction Sub-Station. It is seen that transmission charges billed

by MSETCL to Indian Railways are of the order of Rs 7.20 Crore per month for 330 MW flowing into CTU system. which is about Rs 2.20 Lakh/MW/month.

The charges levied to DD & DNH for using the above corridor are about 0.73 Lakh/MM/Month. Applicable transmission charges for DD &DNH

were worked using contract path method in consultation with MSETCL in FY 2010-11 under Item No. 3.3 of minutes of 56th CCM and Item 3.3 & 3.4 under 15th TCC/WRPC Meeting.

RGPPL requested that transmission charges applicable to 330 MW share of Indian Railways from RGPPL for using transmission corridor of

Dabhol-Nagothane-Padhge to connect to CTU network be reviewed by MSETCL based on contract path method as done in case of DD & DNH.


Item No 13

Performance Guarantee test of NTPC Generators

Background: In 523 OCC NTPC informed that Performance Guarantee Tests(PG) are planned to be conducted in NTPC Solapur and Mouda and requested

beneficiaries to provide schedule so as the PG test can be carried out successfully. MS WRPC opined that PG test is a once in a lifetime activity of generator

and hence suggested that States provide the requested schedule to NTPC for successful completion of PG test of its units.


Item No 14

Allocation of open cycle share of Kawas to all beneficiaries

SLDC Gujarat vide letter dated 05.11.19 (copy enclosed at Annex 14) informed the following:

In recent past, on pursuance of Gujarat requirement, NTPC - Kawas has arranged APM gas fuel for economical operation.

During initial open cycle operation of about six hours (must to bring unit in combined cycle), Gujarat is only requisite the requirement of

around 90 MW which is well above the allocation at 4.27 Rs variable cost.

All beneficiaries are punching their requisition when machine comes in combined cycle leading to loss of share (Gujarat share is 47 MW in one

machine in combine cycle) to Gujarat who has extended support of open cycle operation (90 MW of about six hours at high variable cost) for bringing gas turbine on bar.

Gujarat requested to all beneficiaries to contribute its share in open cycle operation mode if they desire to avail their share in combined

cycle.

A. Long pending CVT replacement in 220 kV Kawas-Icchapur line-1 at Kawas end

In the CT and CVT testing carried out by NTPC, it was found that

measured ratio of R and B phase CVT is lower (3-

5%) than expected level. Therefore, the main meter of 220 kV Kawas-

Icchapur line-1 at Kawas end is given Bus PT input while check

meter was given faulty line CVT input. The main meter is being used

for computing NTPC Kawas injection.

In the 80th CCM, it was discussed that line CVT at Icchapur end in

220 kV Kawas-Icchapur line-1 shall be replaced as it was confirmed

by the tests that R & B phase CVT‟s are showing irregular results.

Further, after replacement of faulty CVT with a healthy CVT, the main

meter shall be provided the line CVT input and its readings shall be

validated by WRLDC with standby meter readings.

In the 81st CCM, GETCO informed that the work will be done in the

month of May 2019, however the work is yet to be finished.

GETCO may apprise the committee the cause of the delay and

tentative date by which the work shall be completed. B. Replacement of one check and two standby meters at NTPC

Kawas

The following meters installed at NTPC Kawas have a time drift of about 1 hour as seen in data validation at WRLDC.

• HV side of GT-1A (NP-5529-A, Elster make)

• HV side of GT-1B (NP-5445-A, Elster make)

• 220 kV Kawas-Icchapur line-2 (check meter, NP-5457-A, Elster make)

The time drift has been confirmed from the unit outages timings in the outage report.

However, time display in the meter does not reflect the time drift. Thus it may be inferred that the meter is faulty.

An email was sent to NTPC Kawas and PGCIL Navsari s/s on

01.10.2019 regarding checking and correction of time drift. Further,

NTPC informed vide email dtd. 18.10.19 that they have done time

drift correction on 14.10.19, however the issue was not resolved.

WRLDC informed the same to NTPC Kawas and POWERGRID vide

email dtd. 25.10.19.

Thus, these three meters (NP-5529-A, NP-5445-A and NP-5457-A)

need to be replaced with meters of different make.

CHAPTER – 11

COMPUTATION OF CAPACITY CHARGES AND ENERGY CHARGES

42. Computation and Payment of Capacity Charge for Thermal Generating

Stations:

(1) The fixed cost of a thermal generating station shall be computed on annual basis

based on the norms specified under these regulations and recovered on monthly basis

under capacity charge. The total capacity charge payable for a generating station shall

be shared by its beneficiaries as per their respective percentage share or allocation in

the capacity of the generating station. The capacity charge shall be recovered under two

segments of the year, i.e. High Demand Season (period of three months) and Low

Demand Season (period of remaining nine months), and within each season in two

parts viz., Capacity Charge for Peak Hours of the month and Capacity Charge for Off-

Peak Hours of the month as follows:

Capacity Charge for the Year (CCy) =

Sum of Capacity Charge for three months of High Demand Season +

Sum of Capacity Charge for nine months of Low Demand Season

(2) The Capacity Charge payable to a thermal generating station for a calendar

month shall be calculated in accordance with the following formulae:

Capacity Charge for the Month (CCm) =

Capacity Charge for Peak Hours of the Month (CCp) +

Capacity Charge for Off-Peak Hours of the Month (CCop)

end of nth Month in a Season;

NAPAF= Normative Annual Plant Availability Factor.

(3) Normative Plant Availability Factor for “Peak” and “Off-Peak” Hours in a

month shall be equivalent to the NAPAF specified in Clause (A) of Regulation 49 of

these regulations. The number of hours of “Peak” and “Off-Peak” periods during a

day shall be four and twenty respectively. The hours of Peak and Off-Peak periods

during a day shall be declared by the concerned RLDC at least a week in advance. The

High Demand Season (period of three months, consecutive or otherwise) and Low

Demand Season (period of remaining nine months, consecutive or otherwise) in a

region shall be declared by the concerned RLDC, at least six months in advance:

Provided that RLDC, after duly considering the comments of the concerned

stakeholders, shall declare Peak Hours and High Demand Season in such a way as to

coincide with the majority of the Peak Hours and High Demand Season of the region to

the maximum extent possible:

Provided further that in respect of a generating station having beneficiaries

across different regions, the High Demand Season and the Peak Hours shall correspond

to the High Demand Season and Peak Hours of the region in which majority of its

beneficiaries, in terms of percentage of allocation of share, are located.

Sub:- Non-applicability of Delay Pa5rment Charges towards Fa5rment of, DSM BiIl for3r-12.2A1a.

Ref.:- 1) L,etter no.WRPC/Comml.-Il4/ABTDSM /2OLB/12.51575 dtd.31.O1.2019.2) I*tter no.WRPC/Comm1.-Il4/ABTDSM /ZOLB/12.5A-1.2A/2O3O dtd. L8.O2.2O79.

Sir,

This office had received DSM bill vide u/r (1) wherein bill period mentioned was3L.L2.2OLB to O6.01.2019. It was evident from the covering letter that tJ:e pa5rment mentionedwas for the week from 31.L2.2078 to 06.01.2O19 amounting to Rs.2,77,49L/- & it was dulysigned- This offrce has paid Rs.2,'l"l ,491/- vtde Cheque No.U9'/'/4'2 dtd. tJ'|.O2.2O19 within thetimelines of DSM bill due date.

Further, this office was in receipt of revised bill with period mentioned as O1.01.2019 to2O.O1.2O1,9 vide u/r (2) amounting to Rs.3,O6,O6,9O3/-.However, considering the weeklvpattern of bills issued by IVRPC, this oflice had inadvertently deducted the charges i.e.Rs.2,77,49L/- far 31.12-2018 from the said trill. The payrnent was done by this oflice forRs.3,03,29,412/- vide Cheque No.O97755 dtd.27-O2.2O19 i.e. with deduction of charges for31.12.20L8.

After scrutinizing, it was found that the amount of Rs. 2,77,491/- was only for31.L2.2O18. Thus, the said amount was immediately paid by this office through cheque No.

LO9829 dtd. 15.07 .2079.

It is pertinent to note that Maharashtra State L,oad Dispatch Centre has never defaultedpayment against the timelines of DSM bills and therefore, DPC may not be charged for therespective period i.e. 31.72.2OL8 as it is inadvertent error on both sides. In view of above, DPCshould not be levied on the amount Rs.2,77,491/-.

Your's faithfuliy,Thanking you.
