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 4/20 Sep’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.
