5. Ananthapuramu (NP Kunta) Ultra Mega Solar Park
(a) SEM issue
The following had noted in the 36th Meeting of SRPC:
In the Meetings of Commercial Sub-Committee, it was notedthat SEM readings of
all ACME SPDs during night hours were mostly zero.
The Commercial Sub-Committee had suggested to swap the non-recording SEMs
with the SEMs recording drawal during night hours, so as to ascertain the reason of
malfunction. APSPCL and ACME SPDs were requested to mitigate the problem so
that precise energy accounting of all SPDs of the park could be carried out.
Minutes of the42ndMeeeting of Commercial Sub-Committee held on 22.10.2019 3/20 The discrepancy of the SEM persists and hence the average drawals are being
computed to assign drawal values to these SPDs to assess deviation.
Subsequently, APSPCL vide letter dated 24.06.2019 (ANNEXURE-III) had requested
PGCIL for certification of SEM meters connected at 33 kV feeder and standby meters at
220/33 kV Pooling Sub-Station at NP Kunta Site of Ananthapruamu Ultra Mega Solar Park
(1500 MW).
The SEM readings of all ACME SPDs and AZURE for 1stSeptember 2019 are furnished at
ANNEXURE-IV. The SEM values continued to have the same discrepancy. Hence, to
assess deviation, the drawal by these SPDs were computed based on the average drawal.
Deliberation in the meeting:
a) It was noted that PGCIL vide letter dated 21.10.2019 (ANNEXURE-V) had intimated
that SRTS-I do not have any infrastructure/facility for calibration and certification of
SEMs. Hence, APSPCL requirement of certification of 0.2 class SEMs may not be
possible by POWERGRID.
b) APSPCL informed that SEM meters of AZURE started recording during night time
after increasing the lighting load. Similar action in other SPDs also would be carried
out to address the issue.
c) It was observed that the CT ratio adopted needed to be verified. Smaller CT ratio may
solve the non-recording issue. The Commercial Sub- Committee advised APSPCL to
verify the CT ratio. APSPCL/SPDs may avail the services of Meter testing
Laboratories.
d) After deliberation, it was agreed that APSPCL would verify the CT ratio of the SEMs
with night recording issues / the meters may be tested using NABL accredited mobile
laboratory or at any accredited laboratory within one month (before 22nd November
2019).
(b) Metering Scheme
APSPCL vide e-mail dated 26th September, 201 had requested to approve the Metering
Scheme for 1000 MW at NP Kunta Site of Ananthapuramu Ultra Mega Solar Park (1500
MW).
SRLDC vide e-mail dated 19.10.2019 had informed that the proposed metering philosophy
for SB Energy SPD (250 MW) at NP Kunta solar Park. Accounting of injection for SB
Energy would be measured at 220 kV PSS-4 lines 1 &2 at NP Kunta (PGCIL) end.
Commercial Sub- Committee approved the Metering Scheme (ANNEXURE-VI) for 1000
MW at NP Kunta.
APSPCL/ SPDs shall furnish the details of the installed SEMs in the specified format to
SRLDC.
6. Transmission Charges Pertaining to Kudgi STPS
The following had been noted in the 41stMeeting of Commercial Sub-Committee held on
20th June 2019:
(i). PGCIL had informed that as per the RTAs issued by SRPC during Aug’17 to
Minutes of the42ndMeeeting of Commercial Sub-Committee held on 22.10.2019 4/20Sep’18, bills for an amount of Rs 363 Cr. were raised on NTPC towards the LTA
charges for the un-commissioned generation, however, NTPC did not make the
payment and hence there was shortfall of Rs 363Crs in recovery by the ISTS
Licensees from the PoC Pool.
(ii). PGCIL had stated that in a petition filed by NTPC against the billing, CERC directed
that the LTA be operationalized from the COD of Associated Transmission System
and the proportionate YTC of the ATS be collected from NTPC till commissioning
of their pending generation. SRPC issued the revised RTA for NTPC revising the
billing amount to Rs 304.10 Cr. On relevant billing by CTU, the amount has been
paid by NTPC.
(iii).PGCIL had further stated that there is still a shortfall of Rs 59 Cr. in recovery in the
PoC Pool, which needs to be collected from the other DICs in the PoC Pool through
adjustment in the POC bills upon revision of PoC slab rates / SR-RTA for the period
August 2016 to September 2018. Applicable credit notes for revision of NTPC
billing as per CERC order were accounted during July 2018- September 2018 Bill-3
and it is to mention that refund to the DICs doesn’t arise as there is still an under
recovery of Rs 59 Crs which needs to be collected upon revision of PoC rates by
NLDC/CERC. As desired, the YTC details of ATS for Kudgi evacuation and LTA
details have been furnished to NLDC with copy to SRPC vide letter dated
18.02.2019.
(iv). PGCIL had requested KSEBL to immediately release the withheld amounts of

furnish the necessary details to facilitate SRPC Secretariat to proceed further. In reply to
this letter POSOCO vide letter dated 28th June 2019 had informed that Implementing
Agency had carried out the PoC rate re-computations and submitted the results to CERC.
The revised PoC rates order is pending with CERC.
The following had noted in the 36th Meeting of SRPC held on 12th July 2019:
The details of billing period as per the issued RTA in respect of above to the
beneficiaries/NTPC. Also billing period details to be carried out as per CERC Order.
The revised RTA pertaining for the applicable period would be issued after CERC
Order on revised PoC Rates.
Deliberation In the Meeting:
It was noted that CERC had issued revised PoC Rates vide Orders dated 10.10.2019.
SRPC Secretariat informed that they were in the process of revision RTA/RTDA from July
2017 to September 2019 as per the revised PoC rates notified by CERC.
Minutes of the42ndMeeeting of Commercial Sub-Committee held on 22.10.2019 5/20KSEBL informed that an amount of Rs.3.87 crores disallowed in the bill 3 of PGCIL had
not released so far. The PoC slab rates were revised but not starting from August 2016.
Revision in RTA was required for the period August 2016 to June 2017 also.
TANGEDCO stated that the Billing of transmission charges from August 2016 to June
2017 should also be billed on the generator bilaterally, for which CTU may take necessary
action.
PGCIL informed that the charges for the period August 2016 to June 2017 would be taken
care in the BILL-3 after the receipt of the revised RTA/RTDA as per CERC order.
7. Inclusion of all Bilateral Billing (including RE Generators) in RTA.
In the 41stMeeting of Commercial Sub-Committee, PGCIL had stated that the exemption for
transmission charges as per MoP Order dated 13.02.2018 is applicable after commissioning
of RE generation and fulfilment of other conditions. Considering the commissioning of RE
generation in line with MoP Order, bilateral bills on the delayed RE generators are being
raised within Jun 2019. However, it may be mentioned that Amendment 6 to CERC Sharing
Regulations stipulates that the exemption of transmission charges is applicable after the COD
of the generation and the ambiguity between the commissioning / COD as per MOP Order /
Regulations is taken up with CERC for clarification.
PGCIL had informed that the details of bilateral billing (upstream and downstream) would be
furnished from June 2019 onwards (including the period from the date of operationalization
of LTA).
SRPC vide letter dated 04th July 2019 had requested NLDC and PGCIL to communicate all
bilateral billings (including RE) for inclusion in RTA to comply with CERC orders.
The following had noted in the 36th Meeting of SRPC:

TCC had suggested CTU to furnish complete details of bilateral billing (including
RE) for inclusion in RTA in compliance to CERC Order.
Deliberation in the meeting:
TANGEDCO stated that CTU may bring on record the details of bilateral billing details of
other generators including RE generators who have not commissioned their projects after
CoD of associated transmission projects. Further, TANGEDCO urged the forum to direct the
CTU/SPPDs to share the SPD wise/generator wise details of CoD / PPA tie-up with
beneficiaries so as to ascertain the LTA waiver granted to such RE generators.
TANGEDCO further insisted CTU to collect the transmission charges payable by BHAVINI
(KPFBR) as per the direction of APTEL and refund the same to beneficiaries.
SR-II, PGCIL informed that all the details were to be obtained from CTU.
Commercial Sub-Committee suggested PGCIL to collect all the details SPD wise/generator
wise details of CoD / PPA tie-up with beneficiaries etc. for inclusion in RTA.
SR-II, PGCIL agreed to furnish the details as and when received from CTU.
Minutes of the42ndMeeeting of Commercial Sub-Committee held on 22.10.2019 6/208. Implementation of Automatic Meter Reading (AMR) in Southern
Region /Technical Specification of Special Energy Meters
Need for AMR scheme had been felt keeping in view high RE ingress, amendments in DSM
Regulations, SCADA related issues etc. In the 24th Meeting of SRPC held on 15th March
2014, SRPC had approved implementation of the AMR scheme by POWERGRID
The following had noted in the 35thMeeting of SRPC held on 02nd February 2019:
PGCIL had stated that in NR 1,400 SEMs are integrated with AMR facility also. There
had been some integration issues and reliability was not as good as anticipated. In ER
nearly all SEMs had been provided with AMR facility but some communication issues
are being faced. Keeping in view, CERC Regulation on Renewable Integration,
CERC/POSOCO has shown interest on 5 minute block recording SEMs. A pilot project
has been given to PGCIL wherein 126 SEMs are to be installed. The Order has been
placed on 09.01.2019 and SEMs would be installed in 3 months. In a development in
WR, need for 5 min SEM with AMR facility had been brought out. Final specifications
had been prepared and they had gone ahead for tendering and in one month Orders will
be placed for 1,800 meters.
After deliberations, it had been agreed that PGCIL would furnish the technical
specifications finalized in WR. These would be circulated to all the constituents and
keeping the SAMAST guidelines and other requirements (AMR, 5 to 15 minutes online
configurable, SCADA integration possibility etc), Committee of Stake holders would
finalize the specification for SEMs in SR. The same would be passed on to
POWERGRID for implementation in SR. SRPC would be requested to approve the
Committee Recommendations as and when they are finalized. STUs would take
appropriate action for their schemes separately, without linking it with this project.
SRPC had approved the way forward in this regard as had been proposed by TCC.
In the 41st Meeting of Commercial Sub-Committee, PGCIL had agreed to come out on the
scope of the work (including SEMs on all interstate feeders to be owned by respective
transmission licensees or otherwise) and on the sharing principle for the complete AMR
scheme.
The following had noted in the 36th Meeting of SRPC:
PGCIL informed that agreement has been entered in Western Region for on time
payment settlement and for keeping some spare SEMs. The same is proposed for
Southern Region also. The charges would be apportioned among the entities based on
the number of SEMs. Entities would have the option to pay in advance or later based
on the invoice.
It was agreed that PGCIL would take up the implementation of SEMs and raise
invoice on utilities. PGCIL would inform the stakeholders about the cost implications
(estimated cost and after implementation the final cost).
Deliberation in the meeting:
PGCIL informed that the cost implications would be furnished within two weeks.
The utilities requested PGCIL to expedite implementation of AMR in SR.
