ITEM NO. 8.4 PERMISSION REQUEST FOR ANTI-THEFT CHARING OF +/- 800 KVHVDC CHAMPA – KURUSHETRA LINE ( IN 2 SECTIONS OF 15 KMS LENGTHIN ANUPUR & DINDORI DISTRICTS OF MP).

GM(AM), WRTS-II, PGCIL Vadodara vide letter dated 26.05.2016 informed that

construction activities of +/- 800 kV Champa – Kurukshetra HVDC line is in advance

state of completion. This shall make an important inter-regional link between WR-NR

and benefit for reliability and bulk energy transfer. One package of line between location

nos.418 to 814 in MP state of Anuppur & Dindori district has been completed. The

charging of subject transmission line is feasible upon readiness of terminal stations at

both ends of line. This is expected to be ready by July 2016.

In this regard, it is pertinent to mention that during last six months, many incidents of

conductor theft in subject line have been encountered under Dindori & Anuppur District

of MP state. This is causing serious execution problem for us due to conductor qty. as

well as rework in transmission line. Hence, it is essential to protect theft of conductor as

well as prevent any damage/break down to tower due to unbalancing, which has

fortunately not happened till date.

He requested for idle charging of part of 800 kV HVDC Champa – Kurukshetra line ( 2

sections of 15 kms each) has been explored in theft affected portion. Thus proposal is

illustrated as below:-

1. Pole-1 of 800 kV HVDC Champa-Kurushetra line proposed to be charged with

Top phase of Ckt.2 of 400 kV Anuppur-Jabalpur line. Detailed sketch of same is

enclosed at annexure 1 (between line loc.no.100/0 & 101/0 of HVDC line and

Kurukshetra line in above section.

OCC discussed the above matter & opined that permission of anti-theft charging of 800

kV HVDC Champa – Kurukshetra line at Extra high voltage (400kV) is not advisable,

whereas if PGCIL willing to anti-theft charging, it can be done at 11kV, 33kV or 66kV

level.

However GM, WRLDC informed that as per CEA guide line on anti-theft charging,

WRTS-II, PGCIL Vadodara may directly approach to WRLDC. WRLDC will look after the

possibility of anti-theft charging as per the existing CEA standards/guidelines.

ITEM NO. 8.6 SHEDULE FOR NTPC JHANOR GPP FOR GGF GAS UTILISATION.DGM NTPC HQ-I informed that at present Jhanor station is getting schedule so the

GGF is getting utilized. It is requested to facilitate and support Jhanor minimum one GT

operation to continue the GGF consumption in Manson/low demand perioed as well. If

The Jhanor gas station goes under close reserve due to less /no requisition from

beneficiaries constituents. This will be resulting in non utilisation of GGF Gandhar gas

field gas.

He informed that non-availability of generation schedule, the station is not able to draw

any ONGC’s South Gujarat gas from GAIL which can only be taken at Jhanor Gandhar

GPS. The gas suppliers are compelled to flare gas due to low off take by consumers.

GAIL has issued letters mentioning that the continuous off take of GGF gas to be

ensured otherwise, they would be constrained to raise Take-or-Pay clause in line with

the contractual obligations. The GGF is in APM category which is the cheapest gas in

the country, any shortfall in its drawl may lead the Govt. to reduce allocation of the

same.

The matter was discussed in 28th WRPC meeting dated 04.03 2015 and subsequent

OCCM, the utilisation of the GGF was in principal agreed and constituents were advised

to give schedule accordingly.

In view of above, he requested that sufficient generation schedule may be given to

Jhanor-Gandhar station so that the station can operate at least at its technical minimum

load (149 MW) in combined cycle mode and can draw the committed gas from GAIL to

avoid Take-or-Pay situation.

Please note that if M/S GAIL if invokes take or pay clause than such amount will have

to be loaded to fuel cost to be recovered from beneficiaries.

GM, NTPC expressed that the point has been agreed in previous WRPC/TCC/OCC

meetings and all the beneficiaries must support for the same. He once again requested

all the beneficiaries for giving schedule to Gandhar for one GT technical minimum

schedule (149MW) as agreed in previous forums. This is in the interest of all the

beneficiaries, GGF being the cheap gas power is available to them and also important

for the utilisation of the natural resource which is otherwise wastefully flared up.

ITEM NO. 8.9 PROBLEMS IN WEB SCHEDULINGChief Engineer, SLDC Chhattisgarh informed that while scheduling through WRLDC new

web scheduling software, some problems/suggestions were forwarded to WRLDC, needs

to be resolved/incorporated:

17

484th OCC MINUTES

(a) For preparation of requisition by State for ISGS entitlement, the pages related to

every ISGS stations are to be opened separately which is quite inconvenient

and time consuming. If the same is provided State wise, incorporating

entitlement of all central sector stations in a single page, preparation and

submission of requisition will be much easier and convenient.

If the above is not possible then in the requisition & schedule menu, the

sequence of central sector ISGS in drop box may be kept same as that is

being uploaded in the website of WRLDC which will ease the down loading

the same for further use.

(b) Drawl Schedule Display in WRLDC Website:-The drawl schedule of differentStates with their embedded entity are presently being displayed in the WRLDC

website needs to be simplified by adding some suffix to the name of ISGS

station. This will help in using these data further in our internal software. At

present the share of the State in ISGS as well as in bundled solar power are

being displayed with the same name of ISGS station. Similarly the share & URS

of embedded entity of CSEB i.e. BSP and State share in NSPCL also needs to be

displayed by adding some suffix to it.

GM, WRLDC ensured that the above points suggested by SLDC, Chhattisgarhcan be considered & accordingly try to accommodate on the new software.

(c) Despite discussion in last OCCM, the issue of data from Raipur & Bhatapara

PGCIL stations in midnight has not been resolved.

PGCIL informed that being above sub stations are unmanned, therefore it will be

difficult to provide the data at midnight.

Member Secretary suggested that CSPTCL can commissioned AMR at above sub

stations to get the online data & requested PGCIL to find some amicable solution for

furnishing the data from above stations.

9.2Sale of Un requisitioned surplus (URS) Power in line with provisions ofRevised tariff policy —

Reference is invited to Office Memorandum dated 09th May 2016 from

MoP(Copies enclosed at Annexure-9.2) wherein State Govt / State DISCOM

were advised to use para 6..2(1) provision of Tariff policy and give their consent

to the respective Generating stations for sale of such URS Power in the market

through Power Exchange. Relevant extracts from the Tariff Policy are quoted

below:

"Power stations are required to be available and ready to dispatch at all times.

Notwithstanding any provision contained in the Power Purchase Agreement

(PPA), in order to ensure better utilization of un-requisitioned generating capacity

of generating stations, based on regulated tariff under Section 62 of the Electricity

Act 2003, the procurer shall communicate, at least twenty four hours before 00.00

hours of the day when the power and quantum thereof is not requisitioned by it

enabling the generating stations to sell the same in the market in consonance

with laid down policy of Central Government in this regard. The developer and the

procurers signing the PPA would share the gains realized from sale, if any, of

such un-requisitioned power in market in the ratio of 50:50, if not already provided

in the PPA. Such gain will be calculated as the difference between selling price of

such power and fuel charge. It should, however, be ensured that such merchant

sale does not result in adverse impact on the original beneficiary(ies) including in

the form of higher average energy charge vis-a-vis the energy charge payable

without the merchant sale. For the projects under section 63 of the Act, the

methodology for such sale may be decided by the Appropriate Commission on

mutually agreed terms between procurer and generator or unless already

specified in the PPA."

Member Secretary, WRPC proposed to hold a separate meeting on 23.6.16 to

discuss sale of URS of generators under section 62 in Power exchange along

with the meeting on Draft Procedure prepared by NLDC for RSD mechanism.

9.3Mechanism for compensation for station heat rate and auxiliary energyconsumption for low unit loading and for start-stop during RSD

4th Amendment of IEGC issued by CERC on 6th April 2016, provides as under:

6.3 B (3) “Where the CGS or ISGS, whose tariff is either determined or adopted

by the Commission, is directed by the concerned RLDC to operate below

normative plant availability factor but at or above technical minimum, the CGS or

ISGS may be compensated depending on the average unit loading duly taking

into account the forced outages, planned outages, PLF, generation at generator

terminal, energy sent out ex-bus, number of start-stop, secondary fuel oil

consumption and auxiliary energy consumption, in due consideration of actual

and normative operating parameters of station heat rate, auxiliary energy

consumption and secondary fuel oil consumption etc. on monthly basis duly

supported by relevant data verified by RLDC or SLDC, as the case may be.”

6.3B (3) (iii) “Where the scheduled generation falls below the technical minimum

schedule, the concerned CGS or ISGS shall have the option to go for reserve

shut down and in such cases, start-up fuel cost over and above seven (7) start /

stop in a year shall be considered as additional compensation based on following

norms or actual, whichever is lower:”

6.3 (3) (vi)“The compensation shall be borne by the entity who has caused the

plant to be operated at schedule lower than corresponding to Normative Plant

Availability Factor up to technical minimum based on the compensation

mechanism”

6.3B (7)”The RPCs shall work out a mechanism for compensation for station heat

rate and auxiliary energy consumption for low unit loading on monthly basis in

terms of energy charges and compensation for secondary fuel oil consumption

over and above the norm of 0.5 ml/kWh for additional start-ups in excess of 7

start-ups, in consultation with generators and beneficiaries at RPC forum and its

sharing by the beneficiaries finalized by the RPCs.”

Member Secretary, WRPC advised NTPC to prepare the draft mechanism for

compensation and put up in next CCM. If possible the issue could also be

included in a special meeting scheduled on 23.06.2016 for RSD & URS

mechanism.

9.6Extension of SPS signal to KWPCL from Kotra after permanent connectivity toKotra

SPS signal was extended to 400 kV KWPCL through PLCC from Raipur SS, now

said Line has been de-LiLoed and rerouting of signal is required. Matter was

discussed with POWERGRID Kotra and they were advised them to extend the signal

to KWPCL via Raipur SS -Raigarh SS - Kotra PS.

Vide their email dated 20-May-2016, POWERGRID informed that in conventional SS,

PLCC panel are placed nearby hence modification in SPS signal is easy but

Kotra PS has distributed PLCC panels due to which back to back connection is

challenging. Accordingly it was suggested that SPS transmission could be as below -

"SPS Signal to be traveled either through Raipur or directlty from origin through fiber

and further distribution will be done at Kotra PS."

Representative from KWPCL and POWERGRID has confirmed that the SPS signal is

extended up to KWPCL and generator backing down will be observed as per the

scheme.

9.7Frequency Response Characteristic of Major Generators in WRThe FRC of the major generating stations (500 MW and above)is being reviewed

regularly since DEC 15 starting with 478th, 479th, 480th, 481st, 482nd OCC and 483rd

0.40 Hz rise : 50.04 to50.43 Gen reduction

On 18 May 2016, there was a major event when it was observed that the grid

frequency increased from 50.04 Hz (at 17:31:02 hrs) to 50.43 Hz (at 17:31:19 hrs) of

18.05.2016 due to sudden load throw off of ~ 3500 MW in Northern Region. This

implies a frequency rise of more than 0.4 Hz (within 17 seconds).

Frequency remained outside the IEGC band for a considerable period of time

causing sudden rise in bus voltage and threat to grid security. The event could have

caused Nuclear / Thermal units to trip on overspeed and EHV Lines to trip on OV.

Thus it was a "near-miss" grid event. It is expected that such large and sudden

variation in frequency is arrested by automatic load reduction in generating units

through governor response. This is mandated by IEGC regulation 5.2 as RGMO /

FGMO which has to be complied by all entities.

All Regional Entities were requested by WRLDC to submit the data of frequency vsMW of the units on bar. The response of various entities to be discussed.

A. The data was furnished by all the regional entity generators except the following:I. ESSAR MAHAN: data is still pending
