POSOCO had pointed out that enhancing of the ramp rates would result in further savings in the SCED optimization.

It was noted that as per the Tariff Regulations, 2019-24, POSOCO was to come out with a draft procedure on ramps (with incentivization) by June 2019. The draft was under preparation. This was to be implemented from April 2020.

In the 35th SRPC Meeting it was noted that NTPC would come up with expert

view of OEMs with regard to compliance of CEA Regulations of Ramp Rate of

3%/minute in the control range(sustainability for scheduling etc) and also on the

35 hours duration from cold start for super critical units like Kudgi within a month.

This issue was followed up in subsequent OCC Meetings and there was no

tangible update on the same. Noting that next SRPC Meeting being scheduled on

12.07.2019, SRPC vide letter dated 17.06.2019(Annexure-O) had requested NTPC to expedite the views of OEMs

2.37 SCED Procedure -Implementation of SCED pilot

SRPC vide letter dated 05.04.2019, 11.04.2019 & 12.04.2019 had communicated

some of the issues/suggestions regarding SCED scheduling with NLDC. Reply is

awaited.

In the previous OCC Meetings Generators had pointed out regarding instances of

ramp violation, schedules below TM, schedules above DC, delay in informing the

final generation schedules etc. Also it was noted that generators are paying a

huge amount in Crores to the pool in advance and there was considerable delay

in receiving back the money from beneficiaries. Even penalties are very high.

During pilot period some relaxation should be thought off.

OCC forum again requested SRLDC to take up with NLDC to present on performance of SCED (with respect to details of savings, optimization, station wise Up/Down details, Constraints faced if any etc.)

SRLDC/NLDC to update. 2.38 RE Generators for Reactive Compensation & High Voltage

All the states were again requested to kindly examine and ensure voltage based

MVAR interchange for RE generators.


156th OCC : APTRANSCO informed that they have issued the following TOO in this

regard:

The RE generators are exempted from payment of reactive charges for

drawal of reactive power at voltages are greater than 392 kV. The RE

generator shall absorb reactive power at voltages above 392 kV and inject

reactive power at voltages below 390 kV so as to maintain 400 kV bus

voltages within limits.

KSEBL had informed that they are already following the same(during the

MVAR injection period as per SLDC instruction, reactive charges are

suspended).

TANTRANSCO had informed that TN SLDC(as recommended by SRPC

Forum) had requested REMC wing to empower SLDC for suspension of

reactive charges if it is as per SLDC instructions

It was again suggested that in real time SLDCs may suspend the reactive

interchange charges in case of system requirements (till the voltage based

reactive billing is in place). Blanket approval in this regard for the same may be obtained from the Higher Management by the SLDCs.
