unit and should prepare a separate

Balance Sheet and profit and loss

account for all its SBUs. The

Commission also directs MPPGCL to

pay attention to strengthening its

accounting functions by coding its

accounting policies and inducting

trained accounting professionals. The

accounting function needs to be fully

computerized so that the requirements

of the Companies Act of publishing half

yearly accounting reports and finalizing

the financial statements within six

months of the close of the financial year

can be met.

MPPGCL have requested Hon'ble

Commission to allow preparation of station-

wise balance sheets for the year FY 2010

onwards with computerization of

submitted.

6 Station-wise Cost

Identification

The Commission directs the Company

that in future all tariff petitions must

have station-wise cost identification and

segregation based on thneir individual

Balance Sheet and Profit & Loss

account. Each petition must have

subsections devoted to each of its

stations. The Company must provide

detailed reasons for their projections

and segregations especially for cost

item like interest liability. In the

absence of these details the

Commission shall draw adverse

inference and the costs may be

accordingly reduced.

MPPGCL have requested Hon'ble

Commission to allow preparation of station-

wise balance sheets for the year FY 2010

onwards with computerization of

Accounting Functions, which has been

consented by the Hon'ble Commission with

further directives to implement positively.

However, MPPGCL is submitting Station-

wise cost elements in the Petitions, as

desired by Hon'ble Commission.

MPPGCL shall submit station-wise cost identification in the true-up petition of FY-10 onwards as

desired by the Hon'ble Commission.

7 Setting up Coal

Washeries System

The generation company shall explore

the possibility of setting up of Coal

Washeries System for their Thermal

power stations. The cost benefit

analysis in this regard shall be

submitted to the Commission before

October 2006 failing which the

Commission shall consider revising the

SHR and other perfomance parameters

to bring these to the prevailing level of

similar stations where Washeries and

beneficiation has resulted in improved

performance.

In view of coal shortage in the country at

present, Govt. of India have given

allocation for imported coal to the tune of

6.00 lakh tonne per annum for which the

Company is making necessary

arrangements for blending and

procurement.

As intimated earlier, consultancy services of M/s NTPC have been avaited by MPPGCL from Oct.2010. NTPC Personnel have been deputed in Power Stations as well as in Head Quarter to monitor the performance of the thermal units. Action Plan has been prepared by NTPC and its implementations is in progress. After availing consultancy services, improvement in operating parameters of MPPGCL is observed which is as under:

S.No. Parameter Performance till Oct.2010

Performance till March 2011

1 PLF (%) 53.40 61.10 %

2 AVF (%) 73.46 79.42 %

3 Forced outage (%) 08.34 08.19 %

4 Load Factor (%) 72.69 76.9 %

5 Sp. Oil Cons. (ml/Kwh)

04.52 03.91

It is likely that performance parameters shall be further improved in future.

(2) The reason for no marked up improvement in performance parameters

are attributed to Partial loading of units due to poor coal quality, forced

shutdown of units due to boiler tube leakage, coal shortage, low vacuum

problem and extended overhaul of the units in planned AOH. For the year

2010-11, PLF of MPPGCL achieved was 61.10% and percentages of

Partial loss, planned outages and forced outages were 18.33 %, 12.2%

and 8.19% respectively.

The reasons of low generation, in brief, are as under :

ATPS, CHACHAI:

(a) The reservoir level at ATPS, Amarkantak had become very low due to

low rains last year. This resulted in stopping of 120 MW Unit no.3 from 22

May 2010 to 23 July 2010, resulting in Loss of Generation of 176.88 MU.

(b) The 120 MW Unit no.4 was under Renovation & Modernisation from

25 July 09 to 26 Aug.10 causing 424.41 MU loss of Generation from April

10 to 26 Aug. 10.

STPS, SARNI

(a) Due to poor Coal Quality at STPS, Sarni, in month of April 10 to

March-11, the units had to be run on partial load resulting in the loss of

Generation of 844 MU.

(b) There was acute coal shortage at STPS, Sarni in month of May-10 to

March-11, Due to coal shortage the units had to be run on partial load, the

loss of Generation was 634 MU.

SGTPS, BIRSINGHPUR

(b) At Sanjay Gandhi Power Station, Unit No.4 (210MW) was stopped on

7 July 2010, on account of accident in boiler due to pressurization. Due to

this, Skin Casing of boiler second pass of Economiser intermediate zone,

completely dislodged. The skin casing of all four sides had fallen down and

damaged the feed inlet header and adjoining joints. Buck stay with tie

Channel was also detached, in adjoining area of four sides. Few

Economiser coils, had been damaged. Hanger supports of all Coal Mill

(a) There was coal shortage in SGTPS, Birsinghpur in the month of May-

10 to Sept.-10, Dec.-10 & March-11. On account of this, the units had to

be run on partial load, resulting in the loss of Generation as 471 MU.

pipe lines were also damaged. The damages were severe, leading to

longer AOH period. Unit was synchronized on 2 November 2010.

Accordingly unit was out for 78 days in excess of schedule which lead to

loss of Generation of 383 MU.

The detailed analysis w.e.f. April 10 to March 2011 in respect of forced

outages, of the units are indicated in Annexure-A & B. Similarly detail

analysis in respect of Partial Losses are indicated in Annexure-C.

4/ In order to reduce the forced outages and Partial losses in future,

MPPGCL has taken consultancy services of M/s. NTPC & award in this

respect has already been placed vide order No. 07-03/OSG/NTPC/2850

dtd. 16.08.2010.

M/s. NTPC vide letter dtd. 15th April 2011 has submitted Action Plan & its

present status for the year 2011-12 a copy of which is enclosed. All out

efforts shall be made to rectify the defects and take other corrective

measures in upcoming AOH’s, this year.

Consultancy wing of M/s. NTPC has deputed their officers at all power

stations & at HQ level to monitor the performance parameters of the units.

M/.s NTPC had engaged their team in Oct. 2011 since then,

improvement in performance parameters have also been indicated in the

subject letter dtd. 15.04.2011.

As far as measures to reduce Station Heat Rate is concerned unit wise

hourly data of critical parameters affecting Heat Rate is now being

monitored in all the three power stations. Based on this data, action plan

will be chalked out for implementation during Annual Overhaul of the units.

In order to ascertain the quantum and area where losses are taking place

which is resulting in higher station heat rate, steam path audit in one 210

MW turbine of Unit No. 7 of STPS, had been conducted and it was noticed

that heat rate deterioration of 396.95 KJ/Kwl was there in opening audit

and after maintenance in COH the same could be reduced to 216.93

KJ/Kwh (including audit). Thus only 45.34% reduction could be achieved

in COH. It is felt that the balance loss will be reduced only when

comprehensive R&M could be done. The condition of other turbines is

assumed to nearly same.

As far as Auxiliary Power Consumption, is concerned current monitoring of

units wise HT equipments (BFP, ID,FD, PA Fans & Mills) will be done by

NTPC/side officials. Train efficiency test of BFP’s of all unit will be

conducted shortly as indicated in Action Plan of M/s. NTPC.

5/ MPPGCL has also made strategy for the year 2011-12 & proposed to fix

target of 76.4% by reducing partial loss, planned & forced outage to the

tune of 11.00 % ,5.4.% & 7.00% respectively.

Maintenance programme of the units & work to be carried out are as

under:

ATPS, Chachai (2x120 MW + 210 MW)

The Renovation & Modernization of Unit NO. 4 (120 MW) has been

completed and unit is presently running on an average load of 105-110

MW, since the unit has returned back into system after R&M, AOH of this

unit for FY 12, shall be deferred.

Renovation of Unit No. 3 (120 MW) is under progress and is likely to be

back in Sept., 2011. It is expected that this unit will also run on 105-110
