The issue of replacement of UFR and df/dt relays at Jamalpur and Sangrur S/s is being
discussed since 110th OCC meeting. PSTCL has informed that relays have been
replaced at both the location whereas BBMB has informed that relays does not have
df/dt feature.
In 118th OCC meeting it was decided that joint testing of the relays would be carried out
by PSTCL and BBMB and report of testing would be submitted in the next OCC.
In 119th OCC meeting PSTCL informed that joint testing could not be carried out.
PSTCL and BBMB were requested to carry out the joint testing and report in the next
OCC meeting.
In 120th OCC meeting, representative of PSTCL and BBMB informed that they will
resolve this issue by 15.03.2016.
In 121st OCC meeting representative of PSTCL and BBMB informed that this issue will
be resolved by 31st March 2016. In 122nd OCC meeting BBMB informed that the request
of PSTCL regarding inserting the time delay of 200 m sec in addition to 8-10 measuring
cycle in the df/dt relays supplied by PSTCL at 220 kV substation Jamalpur & Sangrur is
not as per guidelines of NRPC. Therefore, the further action is to be taken by the
PSTCL for rectification/replacement of the relays so that the same can be
commissioned without any time delay in addition to the measuring cycles. In 123rd OCC
meeting both BBMB and PSTCL agreed to resolve the issue and replace all static relays
with numerical by Dec 2016.
PSTCL may update the status.
(iii) (a) On scrutiny of report ending December, 2015/March, 2016 it has been observed that
there are sub-stations in UPPTCL, HVPNL BBMB, and HPSEB Ltd. where static UFR
relays has been installed whereas as per the procedure for mock testing all UFR relays
should be of Numerical types. UPPTCL, HVPNL, BBMB and HPSEB Ltd. may indicate
the plan to change the relays.
PTCUL-The Electromechanical/Static type UFRs are still installed on
(b)
Transformers/feeders emanating from 132 kV Majra & Jwalapur sub-stns.and 220 kV
Ramnagar, Roorkee & Rishikesh sub-stns. respectively.
In 119th OCC meeting PTCUL informed that Electromechanical/Static type UFRs would
be replaced with Numerical Relays by 31.03.2018.
OCC expresses concern about the time schedule given by PTCUL for replacement of
Electromechanical/Static with Numerical Relays. In 120th OCC meeting, representative
of SLDC, Uttarakhand informed that they had taken up the matter with STUs and would
submit the revised time schedule by next OCC meeting. In 122nd OCC meeting
representative of PITCUL informed that replacement of Electromechanical/Static with
Numerical Relays would be completed by 31.03.2017. In 123rd OCC meeting
representative of PITCUL informed that replacement of Electromechanical/Static with

STUs were requested to keep Frequency Generator Kits in sufficient nos. for testing
and provide the same to NRPC officers as and when required. Separate register with
record of UFR operation shall be maintained at all stations wherever UFR installed.
B. Pool for officers for inspection of UFR and df/dt in Northern Region.
C. As per the provisions of IEGC, NRPC Secretariat is required to carry out periodic inspection
of the under frequency relays installed in the region. Accordingly, NRPC Secretariat has
been carrying out random inspection of UFR and df/dt relays installed at various locations
in Northern Region. Further, It has been decided in the 4th meeting of National Power
Committee held on 10th December, 2016 that at least 20% of the Under Frequency Relays
installed in a region should be inspected by respective RPCs in a year beside self
certification being submitted by STUs.
D. But due to manpower constraint at RPC Secretariat it may not be possible to achieve the
target decided by NPC for UFR inspection. In view of this it is proposed that a pool of
officers be constituted with a nomination each from STUs, NRLDC, POWERGRID and
BBMB. Whenever an inspection of UFR and df/dtis planned, a team of 02 officers with one
from NRPC secretariat and other from NRLDC/STU/POWERGRID/BBMB will be
constituted. The officers nominated for inspection will have to claim his TA/DA from his
respective organization. The logistic support to the inspection team shall be arranged by
the organization whose UFR and df/dt relays are being inspected.
E. OCC in its 120th meeting had recommended this proposal for approval to NRPC and same
was approved by NRPC in 33TCC& 37NRPC meeting held at G Noida on 21st&22nd March
2016. Further, nomination of officers received so far from various organizations is as

Violation of NOC issued to NTPC Ltd. for Power transaction through PX (Agenda by
NRLDC)
Ref: - 1. NOC issued by NRLDC dated 06.06.2016 to NTPC Ltd.
NTPC vide their letter dated 02.06.2016 has requested NRLDC for trading of URS power
through PX in line with provisions Tariff Policy. Accordingly, NOC issued by NRLDC dated
06.06.2016 to NTPC Ltd. The PX trades done by NTPC Ltd. during the period 8th June 2016
to 13th June 2016 reveals that, trading in PX has not been as per the NOC issued by NRLDC.
The NOC issued by NRLDC, has clearly stated that NTPC can trade the quantum of power
equal to the URS power of TPDDL (Delhi), UPCL (Uttarakhand) and HPSEB Ltd. (Himachal
Pradesh) only as per the consent submitted by NTPC. It was also mentioned in the NOC that
at any point of time Scheduled Generation (SG) at Ex- bus shall not be more than Ex-bus
Declare Capacity (DC).
On analysing of the traded power during the period from 08th June 2016 to 13th June-2016, It
is observed that Scheduled Generation (SG) of NTPC Ltd. (Rihand STPS –I, II, III & FGUTPS
I, II, III and Singrauli STPS) exceeds the Declared Capacity (DC) as detailed in Annex-XVII.
It is therefore reiterated that before submission of bids for trade in PX, NTPC may ensure that
URS power shall be available from TPDDL (Delhi), UPCL (Uttarakhand) and HPSEB Ltd.
(Himachal Pradesh). It is also requested that after the clearance of trade in PX, NTPC shall
inform to the concerned beneficiary so as to ensure that they do not requisite the quantum of
power already traded in PX.
Members may please discuss.

The following are the observations regarding the recent SPS operations:
•
It was observed from the SCADA data that the 132kV Modipuram-Medical
college flow increased on tripping of other designated feeders from Modipuram
on SPS. Uttar Pradesh may kindly explain for this increase in power flow.
•
Negative power flow of -1 MW is reported for 132kV GSS Merta-Merta road
circuit. Rajasthan may kindly review the radial nature of the feeder.
•
As per the information submitted for above event, Feeders at Jamsher (Punjab),
Kota (Rajasthan), Nara (UP) and 132kV Alwar-Pinan didn’t trip. Major alarm
problem reported at Nara (UP). Utilities may provide details for non-operation of
SPS.
Punjab/Haryana/BBMB may kindly submit the complete feeder wise load relief detail.
In addition to above, critical issue is getting adequate relief and all members may discuss
reasons for such low relief from SPS and ways to plug this gap.
Moreover, on 9th Jun’16, 400kV Rampur-Nalagarh ckt-2 was under non-auto mode. At
15:44:12.200hrs, R-Y phase fault occurred in 400kV Rampur-Nalagarh ckt-2. This line tripping
resulted into Power Flow on second line above 850MW and operation of Case-1 of SPS for
Jhakri/Karcham/Rampur complex. In Case-1, one unit each at Rampur, Jhakri and Karcham
planned to be tripped.
As per PMU plot of Karcham Wangtoo station, slight oscillation observed into the system and
die down after 4-5second. PMU plot of frequency, df/dt and phase voltages are:

As per details, it seems SPS operation is delayed at 400kV Jhakri end. In an earlier incident
also delayed operation of SPS was observed.
NJPC/JSW may kindly looked into the matter and take corrective action.

Revision of Power Map and related information & Operating Procedure for Northern
Region: (Agenda by NRLDC)
The operating procedure of Northern Region & Power Map are being compiled and updated in
line with the Indian Electricity Grid Code (IEGC) regulations 5.1 (f).
NRLDC is in the process of updating & compilation of following two documents:
•
Power Map and related information
•
Operating Procedure for Northern Region
Further, the link of Operating Procedure available on website is as below:
http://nrldc.org/docs/documents/Other%20Documents/Operating%20Procedures%20of%20NR
_2016-17.pdf
Important Grid Elements in NR for 2016-17 has been updated and available on NRLDC
website at following link.
http://nrldc.org/docs/documents/Other%20Documents/Important%20Grid%20Element%20of%
20Northern%20Region-2016-17.pdf
NRLDC has requested in 121st, 122nd & 123rd OCC meetings to inform NRLDC about the
correction/updation/revision/deletion/addition in the respective documents. However,
information is yet to be received from the Northern Regional entities.
33
It is once again requested to send the information by 25th June 2016. The respective
information may also be sent to nrldcso2@gmail.com or nrldcso2@posoco.in.

Regarding transfer of ownership of Inter-state lines (Agenda by PTCUL)
It is to inform that the following inter-state lines are existing in Uttarakhand - UP border area :2.
220 KV Nara-Roorkee line
Line being
UPPTCL
maintained
by
(A) 400 KV Puhana-Muzaffarnagar line :Although this line is being maintained by PTCUL but it is intimated that this line is now
connecting ISTS station of PGCIL (400 KV Puhana) to 400 KV S/s of UPPTCL at
Muzaffarnagar and it will be content that the operation and maintenance of this line be done by
UPPTCL.
(B) 220 KV Nara-Roorkee line :This ISTS line is presently connecting 220 KV Nara S/s of UPPTCL on one end and 220 KV
Ramnagar (Roorkee) S/s of PTCUL. The operation and maintenance of this line is presently
done by UPPTCL although the power flow in this line is from Nara to Ramnagar, Roorkee and
it will be prudent that the operation and maintenance of this line be done by PTCUL.
Members may deliberate.

Detailed Operating Procedure for
Taking Unit (s) under Reserve Shut down and
Identifying Generating Stations to be backed down up to
Technical Minimum Schedule
1. Preamble
1.1.
This Procedure is issued in compliance to Regulation 6.3B.6 of the Central
Electricity Regulatory Commission (Indian Electricity Grid Code) (Fourth
Amendment) Regulations, 2016.
1.2.
The Central Electricity Regulatory Commission (Indian Electricity Grid Code)
(Fourth Amendment) Regulations, 2016 provide the option to Central Generating
Stations (CGS) or Inter State Generating Stations (ISGS) to go for reserve shut
down where the scheduled generation falls below technical minimum schedule.
In addition to above these regulations have specified provisions for
compensating the CGS or ISGS for additional fuel cost towards operating below
normative plant availability factor & for multiple start / stop operations.
1.3.
All the words and expression used in the Procedure shall have the same
meaning assigned to them as defined in the Regulations.
1.4.
This procedure will be implemented with effect from the date of approval by the
Hon’ble Central Electricity Regulatory Commission or any other date as
specified by the Commission.
2. Objective
2.1.
The objective of the detailed operating procedure is to lay down the role of
different agencies, data requirements, procedure for taking generating units
under reserve shut down & methodology for identifying the generating stations
or units thereof to be backed down up to technical minimum schedule in specific
grid conditions such as low system demand, Regulation of Power Supply,
incidence of high renewables etc., based on merit order stacking.
3. Scope
3.1.
This procedure shall be applicable to RLDCs, SLDCs, CGS & ISGS whose tariff
is either determined or adopted by the Central Commission (CERC). In case of a
generating station whose tariff is neither determined nor adopted by the
77
Commission, the concerned generating company shall have to factor the
provisions specified in the aforementioned CERC Regulations in their Power
Purchase Agreements (PPAs) entered into it for sale of power or in order to
claim compensation for operating at the technical minimum schedule.
4. Role of Different Agencies in implementing the Procedure
4.1.

4.3.
SLDCs / Beneficiaries: SLDCs/Beneficiaries shall furnish requisition in the
following manner as specified in IEGC.
i.
SLDCs shall submit the anticipated demand to RLDCs for the next day
as per IEGC.
ii.
SLDCs/Beneficiaries shall furnish requisition to RLDC for the next day (D
day) by 15:00 hours of current (D-1) day. SLDCs/Beneficiaries shall
submit requisition as per their forecasted requirement.
iii.
SLDCs/Beneficiaries shall check the ‘injection schedule’ (R0) issued at
1800 hours by RLDCs for compliance to the technical minimum norms.
78
iv.
v.
vi.
4.4.
In case the injection schedule for a generating station is less than its
technical minimum, the SLDC(s)/Beneficiary (ies) may raise their
requisition up to 55% of entitlement if the original requisition submitted
earlier is less than 55%.
The above procedure shall be followed by the SLDCs/Beneficiaries
RLDCs for all subsequent revisions also.
Any compensation computed as per Regulation 6.3B shall be borne by
the entity, which has caused the plant to be operated at schedule lower
than NPAF but at or above technical minimum schedule based on the
compensation mechanism finalized by RPCs.
Generating stations:
i.
The generating station shall coordinate with its beneficiaries for providing
requisition for making the injection schedule more than or equal to
technical minimum schedule.
ii.
When the scheduled generation falls below the technical minimum
schedule, the generating station shall have the option to go for reserve
shut down under intimation to concerned RLDC & beneficiaries.
iii.
Considering that the minimum economic shutdown hours for units are in
the range of 2-8 hours depending on the unit (details at Annex-1), the
generating stations need to take a pro-active approach in shut down and
restart of units from the view point of merit order.
iv.
The generating station shall submit the details of duration its operation
below normative plant availability factor (NPAF) but above technical
minimum schedule to the concerned RLDC/SLDC for verification on
monthly basis.
v.
The generating station shall submit the required data to
RPC/RLDC/SLDCs as per regulation 6.3B.3.
5. Conditions under which RLDC may direct the generating stations to operate at
a schedule below normative plant availability factor (NPAF) but at or above
technical minimum.
The RLDC may direct a generating station under its scheduling jurisdiction to
operate at a schedule below normative plant availability factor (NPAF) in any of the
following conditions.
i.
Threat to grid security
ii.
To relieve transmission congestion
iii.
Sudden Change in weather condition
iv.
Natural calamities such as earth quake, flood etc ..
79
v.
vi.
vii.

Maintaining adequate reserves
Any other anticipated condition that is likely to affect reliable grid operation
SLDC shall follow the above procedure in case of CGS having 100% share to
the state or any other eligible generator under its control area.
6. Methodology for taking generating station or unit(s) thereof under Reserve
Shut down
6.1.
6.2.
6.3.
6.4.
6.5.
6.6.
The generating station shall submit its declared capability (DC) to RLDC.
The beneficiaries shall furnish their original requisition for the next day (Dday) to RLDC by 15:00 hrs. of the current (D-1) day..
Ex-Power Plant (Ex-PP) dispatch schedule of a generating station in a time
block shall be computed by RLDCs by taking algebraic sum of requisitions of
all beneficiaries of that generating station & same shall be uploaded on
website as revision R0 for next day (D) by 18:00 hours of current day (D-1).
If the net EX-PP injection schedule for a generating station is less than 55%
of the DC on bar the generating station shall intimate the same to all
beneficiaries in the format (A-1) given at Annex-2, with copy to the concerned
RLDC. A-1 has to be issued by the generators by 19:00 hrs of D-1.
The beneficiaries would then review their requisition & submit a revised
requisition by 21:00 hrs to the concerned RLDC.
Based on the revised requisitions received up to 21:00 hrs, RLDC shall
prepare revised injection schedule for concerned the generating station. If the
scheduled generation is less than 55% of DC, the RLDC shall review the
anticipated demand pattern based on the demand forecast given by states
& grid conditions to decide whether technical minimum schedule is required
to be provided to the generating station.
i.
In case the grid conditions demand so in the interest of better grid
operation, RLDC would suo-moto revise the schedule to operate it at or
above technical minimum but below NPAF. While doing so, it is possible
that some beneficary’s requisition would go up to ensure technical
minimum. RLDC shall issue R-1 schedule accordingly and this would be
intimated to the concerned generating station, beneficiaries and the
RPC in format A-2 given at Annex-3. RLDC may also intimate NLDC for
80
invocation of RRAS regulation (up regulation) in case of eligible stations
for keeping the unit(s) on-bar for better grid operation if the grid
conditions demand so. Such up regulation in real time can be triggered
irrespective of prevailing frequency. (Beneficiaries shall not be allowed
to revise the schedule down wards at a generating station where one or
more unit(s) are running under technical minimum schedule with suomoto revision by RLDC.
6.7.
i.
ii.
6.8.
ii.
If the grid conditions do not demand so, the RLDC shall issue R-1
schedule based on the requisitions received. Under such situation, the
generating station shall have the option to go for RSD(Reserve
shutdown) with intimation to beneficiaries, SLDCs, RLDC and RPC in
format A-3 (given at Annex-4).
iii.
In case of exigencies, RLDCs/NLDC could schedule power to the
generating station through RRAS up instruction so as to ensure that the
required units are available on bar and operating at the technical
minimum level of 55%.
Before taking unit(s) under RSD the generating station whose injection
schedule is less than technical minimum schedule, it
May offer an opportunity to the beneficiaries to review their requisitions
particularly to the beneficiaries who had originally submitted requisition as
per full entitlement and would be willing to avail the un-requisitioned power
of other beneficiaries of that station.
May like to sell the requisitioned power under STOA after taking no
objection certificate from the concerned beneficiary/SLDC whose unrequisitioned power is intended to be sold under STOA.
Before taking unit(s) under RSD, the generating station shall bifurcate the DC
in two parts – (i) DC for unit(s) to remain ON-bar & (ii) DC for unit(s) kept
under RSD. The generator shall ensure that the DC for unit(s) kept under
RSD shall not be more than MCR less Normative Auxiliary Consumption. The
DC for unit(s) kept under RSD shall be frozen until its revival from RSD. The
beneficiaries shall continue to bear the capacity charge corresponding to total
DC including unit(s) kept under RSD.
81
6.9.
The above procedure shall be followed for subsequent schedule revisions
also.
6.10.
Once a unit is taken out under reserve shut down (RSD), the period for which
the unit will remain under RSD shall be 24 hours or less if so specified by the
generating station.
6.11.
A beneficiary having entitlement in a station more than or equal to the
capacity of any unit in the generating station may surrender its entitlement for
24 hours or more in consultation with RLDC. In such situation, the RLDC may
facilitate RSD of unit(s) of that station on account of the above beneficiary
only. The drawal schedule of the beneficiary from that generating stating
shall be restricted accordingly for the specified period as requested. The
other beneficiaries shall continue to get their full allocation from the total DC
in that station. This arrangement could also be extended for two or more
beneficiaries in the same generating station.
6.12.
6.13.
6.14.
6.15.
RLDC shall compute & upload entitlements corresponding to DC for unit(s)
ON-bar and DC for unit(s) under RSD separately. The injection schedule in
such case shall be restricted up to ON-bar DC based on the existing
requisitions of beneficiaries.
One or more beneficiaries and the generating station may decide for revival
for unit (s) under RSD with commitment for technical minimum schedule and
mutually agreed ‘minimum run time’ of the unit (s) post revival. RLDC may
also advise the generating stations to revive unit (s) under RSD for better
system operation(IEGC 6.5.20).. In such cases RLDC shall ensure technical
minimum schedule. Compensation shall be admissible towards start-up cost
as per the provisions in the IEGC 4th Amendment.
Regulation of Power Supply: When injection schedule of a CGS/ISGS falls
below technical minimum due to imposition of regulation of power supply
under the CERC (Regulation of Power Supply) Regulations 2010 and/or
CERC order dated 02.09.2015 in 142/MP/2012 by the CGS/ISGS or a
transmission licensee, the generator shall try to schedule the surplus power
through STOA or PX before opting for reserve shut down.
7. Review of the Procedure after 6 months
7.1.
Based on the experience gained through operation for 6 months the
Procedure may be reviewed & modified if felt necessary, in the interest of
system operation.
82
8. Removal of Difficulties:
8.1.
8.2.
Notwithstanding anything contained in this Procedure, NLDC/RLDCs may
take appropriate decisions in the interest of System Operation. Such
decisions shall be taken and subsequently intimated to CERC (on monthly
basis) and the procedure shall be modified /amended, if necessary.
In case of any difficulty in implementation of this procedure, this procedure
shall be reviewed or revised by NLDC with the approval from the
Commission.
