8.0 PERFORMANCE GUARANTEES

The Bidders are required to give the following Guarantees as per Annexure E. 8.1. DECLARED CAPACITY

8.1.1 The MAINTENANCE Contractor shall guarantee Station Availability of 97% for Power Station during each Financial Year.

Formula of ASAF

SAH + SDH

Station Availability Factor = ---------------------

4 X PH

Where : SAH is the sum of AH of Unit #1 to #4

SDH is the sum of DH of Unit#1 to #4

AH is the actual Unit running hours capable of running at full load as defined in clause 1.3.

DH is the deemed availability hours of a Unit as defined in “Deemed Availability”.

PH is period hours during the period under consideration, e.g. 8760 hrs. for a normal year

(8784 hours for leap year).

Any Unscheduled Unit Tripping on account of Mechanical / Elctrical/ GIS/ Instrumentation will

be in account of station availability

8.1.2 “Deemed Availability”

If the Station or Unit is under shutdown or part loaded due to the followings, the hours shall be

considered as Deemed Availability:

1) Reasons attributable to the Grid/ export restriction/ Smelter.

2) Force Majeure Conditions as defined herein.

a) Contractor has to list down the list of critical spares that should be available at site in consultation

and proper justification with the owner for all the equipments with priority on equipments where

redundancy is not available.

190 | P a g e

If the Contractor has not raised any requirement/ justification for the spare prior to the breakdown

the duration of the breakdown will not be considered in Deemed availability. However if spares not

available in consent with the Owner it will be considered in deemed availability. (where redundancy is

not available).

b) Reduction in station availability due to non availability of equipment will be calculated as follows.

i) If standby equipment not available and station generation is 100% then it will be considered as

deemed available.

ii) If equipment not available and station generation reduced then non availability will be

calculated on prorata basis as follows for the non available duration.

(a) Mills – ( CPP-2 (33%) , CPP-3 (25%) of unit availability will be reduced for non availability

of one mill (CPP-540 Minimum 3 mills should be available/ Unit and CPP-1200 Minimum

4 mills should be available/ Unit).

Similarly for BFP & TD BFP (CPP-540 have 2 Nos of MBFP

CPP-1200 Have 1 Nos. MBFP & 2 Nos of TDBFP

(b) For all other equipment - 50% of unit availability will be reduced for non availability of

respective equipments.

8.1.3 Unit or Station availability means Unit available for full load generation as per

Rated Capacity subject to due corrections from the correction curves with respect to

variable factors. However, when the Unit or Station is running at load other than the

Rated Capacity, which is attributable to Owner, Available Hour shall be calculated on

pro-rated basis. But the Unit or Station is running at lower load due to MAINTENANCE

contrator fault, available hour shall be calculated based on actual load on prorated basis. Other

than this,

Deemed Hour shall be applicable.

191 | P a g e

8.2. STATION HEAT RATE LIQUIDATED DAMAGES

Every month Contractor and OWNER jointly has to evaluate the SHR loss attributed due to non-availability of equipment and accordingly MAINTENANCE contractor has to plan to attend the defect and plug the losses. Any such losses required any opportunity will not be considered in SHR loss but rest of the SHR loss will lead to penalty

8.3. MISCELLANEOUS PARAMETERS:

The standards of performance of the plant as described hereunder are referred to collectively as “miscellaneous parameters”.

8.4. SAFETY LEVEL LIQUIDATED DAMAGES

1.1.2 Any Unscheduled Unit Tripping on account of Mechanical / Electrical/ GIS/ Instrumentation will

be in account of station availability. Similarly contractor has to ensure uninterrupted Island

operations and any tripping of unit due to equipment failure will be considered as non-

availability.

1.1.3 “Deemed Availability”

If the Station or Unit is under shutdown or part loaded due to the followings, the hours shall be

considered as Deemed Availability:

1) Reasons attributable to the Grid/ export restriction/ Smelter.

2) Force Majeure Conditions as defined herein.

a) Contractor has to list down the list of critical spares that should be available at site in consultation and

proper justification with the owner for all the equipment with priority on equipment where redundancy is

not available.

If the Contractor has not raised any requirement/ justification for the spare prior to the breakdown the

duration of the breakdown will not be considered in Deemed availability. However if spares not

available in consent with the Owner it will be considered in deemed availability. (where redundancy is

not available).

b) Reduction in station availability due to non-availability of equipment will be calculated as follows.

i) If standby equipment not available and station generation is 100% then it will be considered as

deemed available.

ii) If equipment not available and station generation reduced then non availability will be calculated

on 212ontrac basis as follows for the non-available duration.

(c) Mills – ( CPP-2 (33%) , CPP-3 (25%) of unit availability will be reduced for non-

availability of one mill (CPP-540 Minimum 3 mills should be available/ Unit and

CPP-1200 Minimum 4 mills should be available/ Unit).

respective equipment’s.

1.4 Unit or Station availability means Unit available for full load generation as per

Rated Capacity subject to due corrections from the correction curves with respect to

variable factors. However, when the Unit or Station is running at load other than the

Rated Capacity, which is attributable to Owner, Available Hour shall be calculated on

pro-rated basis. But the Unit or Station is running at lower load due to MAINTENANCE

contractor fault, available hour shall be calculated based on actual load on prorated basis.

Other than this, Deemed Hour shall be applicable.

Monthly Station Heat rate”

The MAINTENANCE Operator shall guarantee to the Owner that Monthly Station

gross heat rate @ 100% PLF and as per correction curve at partial load.

The Gross station heat rate will be computed as follows: -

Monthly station heat rate will be measured by recording the generation readings from the Plant

instrumentation system. The coal consumption and power generation for the month will be taken

for the calculation of Monthly station heat rate. Monthly weighted Average coal GCV (ARB)

shall be considered for calculation of Monthly station heat rate.

Gross heat rate = specific coal consumption * Gross calorific value

Kcal/unit = Actual Coal Consumption / Gross generation * KCAL/KG

Where

1. Coal Consumption shall be calculated by belt weigher installed on belt entering to the bunker

2. Gross Generation shall be calculated by energy meter at generator terminal.

3. Gross calorific value shall be calculated on as received basis (Sampling will be taken during

unloading of rack & truck as per SOP)

214 | P a g e

in accordance with variation in the Gross Calorific Value of the coal supplied to the Plant on as-

received-basis ("GCV-ARB"): The GCV-ARB shall be determined on the basis of a sampling

and GCV-ARB analysis for all in-coming coal carried out by a representative of the

MAINTENANCE Operator (which may be witnessed by a representative of the Owner) as per

applicable ASTM Standards. The Owner may employ a representative on its behalf to determine

the GCV-ARB of the coal and should there be an appreciable deviation from that measured by

the MAINTENANCE Operator's representative, the Owner's determination as to the correct

value of GCV-ARB to be applied shall be binding on all Parties. The SHR calculation carried

out by Owner on this basis shall be final and binding on the Parties as the SHR Guaranteed Value.

Auxiliary Power Consumption (APC)

The MAINTENANCE Operator shall guarantee to the Owner that Auxiliary Power Consumption shall not be higher than as per KPI sheet of 540 MW and 1200MW of the Gross Generation with correction curve at different load.

Auxiliary power consumption will be calculated by power balance method as follows. = Gross Generation (Kwh) + Grid Import - Grid Export – Smelter Consumption Where 1. Gross generation shall be calculated from Generator terminal by energy meter. 2. Import/Export reading shall be taken in plant switch yard. 3. Smelter consumption shall be calculated by installed energy meter at smelter end. 4. For 540MW the grid means Balco internal grid. 1. )
