VARIOUS EQUATIONS USED FOR MONITORING EFFICIENCY OF PLANT:-

1) GAS FACTOR = TOTAL GAS CONSUMED IN SCM / TOTAL GENERATION IN KWH

2) HEAT RATE = GAS CONSUMED SCM * GCV OF GAS KCAL/SCM / TTL GENERATION IN KWH

3) EFFICIENCY = 860 / HEAT RATE.

4) DAILY CAPACITY GENERATION = CAPACITY OF UNIT MWH * 24

5) MONTHLY CAPACITY GENERATION = CAPACITY OF UNIT MWH *24 HRS * NO OF DAYS.

6) DAILY PLF ACTUAL = ACTUAL GENE. / DAILY CAPACITY GENERATION.

7) MONTHLY PLF ACTUAL = ACTUAL GENERATION OF MONTH / MONTHLY CAPACITY GENERATION.

8) FOR PLF WITH BD RSD ADD BD AND RSD IN TO ACTUAL GENERATION IN ABOVE EQUATIONS.

9) PAF ON RUNNING HOURS DAILY = NO OF RUNNING HOUR IN A DAY / ACTUAL HOUR OF THE DAY

10) PAF ON RUNNING HOURS MONTHLY = NO OF RUNNING HOUR IN MONTH / ACTUAL HOUR OF MONTH

11) YARD LOSSES = TOTAL EX BUS SENT OUT AS PER OUTGOING FEEDERS EX BUS GEN RCORDED IN GT1,.

STG1, GT2, STG2 METER

12) AUXILIARY CONSUMPTION = TTL GEN - TOTAL EX BUS SENT OUT AS PER OUTGOING FEEDERS.

13) % AGE AUXILIARY CONSUMPTION = AUXILIARY CONS / TTL GENERATION

14) GEN TRANS LOSS = GEN RECORDED EX BUS SENTOUT METER RD ACTUAL CONS RECORDED ON 6.6 KV BUS

15) GAS CONVERSION MMBTU TO SCM: - SCM= MMBTU *252000 / CAL. VALUE (GCV FOR GAIL & NCV FOR RIL)

16) GAS CONVERSION SCM TO MMBTU: - MMBTU = SCM * CAL VALUE (GCV FOR GAIL & NCV FOR RIL) / 252000

GERC DATA:- (FOR BOTH UNITS)

GERC APPROVED PAF = 80% ; AUXILIARY CONSUMPTION = 3%; HEAT RATE = 1950 KCAL/KWH;

EX BUS VARIABLE COST Rs 2.21/KWH, CONSIDERING GAS COST AS 10.82 Rs PER SCM & GCV 9834

PAF GERC = DECLARED CAPACITY (DC) / (CAPACITY OF UNIT * NO OF HOURS * (1-AUX CONS ie 0.03))

PLF GERC = SCHEDULE FROM SLDC / (CAPACITY OF UNIT * NO OF HOURS * (1-AUX CONS ie 0.03))

GAS DETAILS FOR CCPP 2:- CONT QTY COST OF GAS / TRANSPORTATION

.

RIL GAS :- ORIGIN K G BESIN 14143MMBTU $ 4.34 PER MMBTU

TRANSPORTER 1 :- RGTIL (KG BESIN TO ATAKPARDI) 14143 MMBTU Rs. 67.64 PER MMBTU

TRANSPORTER 2 :- GSPL (ATAK PARDI TO DHUVARAN) 14143 MMBTU Rs. 26.83 PER MMBTU

RIL GAS IS A NCV BASED GAS SO CONVERSION FROM SCM TO MMBTU IS DONE BY TAKING NCV AS CV.

VARIOUS BILLING COMPONENTS. :-

RIL:-

1) GAS COST :- $ 4.205 PER MMBTU

2) MARKET MARGIN :- $ 0.135 PER MMBTU

3) MONTHLY TAKE OR PAY LIABILITY:- MONTHLY OFF TAKE SHOULD BE MORE THAN 80% OF CONT QTY.

4) YEARLY TAKR OR PAY LIABILITY: - YEARLY OFF TAKE SHOULD BE MORE THAN 90% OF CONT QTY.

RGTIL:-

1) TRANSPORTATION CHARGES :- Rs 67.54 PER ACTUAL SHIP QTY

2) MONTHLY SHIP OR PAY PANELTY :- MONTHLY SHIP QTY SHOULD BE MORE THAN 90% OF CONT QTY

3) POSITIVE IMBALANCE CHARGE:- Rs. 67.54 PER MMBTU IF UNUSED GAS IN PIPE LINE IS MORE THAN 1414.3 MMBTU

4) NEGATIVE IMBALANCE CHARGE:- Rs. 202.62 PER MMBTU IF GAS OVERDRAWN FROM PIPE LINE IS MORE THAN 707 MMBTU

GSPL:-

1) CAPACITY CHARGES :- IF SHIP QTY IS CONT QTY THEN Rs 23.63 *ACTUAL MMBTU

2) COMODITY CHARGES: - Rs. 3.2 PER ACTUAL SHIP QTY IN MMBTU.

3) UNAUTHORISED OVERRUN CHARGES ABOVE 10 % :- Rs. 26.83 PER MMBTU OF QTY DRAWN MORE THAN 10% OF SCHEDULED QTY.

4) POSITIVE IMBALANCE PANELTY :- Rs. 107.32 PER MMBTU IF UNUSED GAS IN PIPE LINE IS MORE THAN 1600 MMBTU

5) NEGATIVE IMBALANCE PANELTY :- Rs 107.32 PER MMBTU IF GAS OVERDRAWN FROM PIPE LINE IS MORE THAN 800 MMBTU.

GAS DETAILS FOR CCPP 1:-

AVAILABLE GAS FOR CCPP 1 IS FROM GAIL. GAIL GAS IS GCV BASED GAS. MMBTU ARE CALCULATED CONSIDERING GCV AS CV

TYPE OF GASES

1) APM:- CONT QTY 200000 SCM PER DAY RATE PER SCM = Rs. 7.52667 PER SCM AT 10000 KCAL/SCM NCV

2) RLNG:- CONT QTY 250000SCM PER DAY. RATE PER MMBTU = INDIAN RS COMP Rs 42.61 PER MMBTU + FOREIGN EXC COMP $ 6.5137 PER MMBTU

3) SPOT:- CONT QTY VARIES MONTHLY AS PER REQ. RATE:- PRESENT MARKET RATE OF GAS.

VARIOUS BILLING COMPONENTS:-

APM:-

1) GAS COST :- Rs 7.52667 PER SCM

2) MARKET MARGIN :- Rs. 0.2 PER SCM

3) PRE/ REBATE CHARGES:- REBATE OR PREMIUM FOR GAS NCV DIFF FROM CONTRACTED 10000KCAL/SCM.

4) FIXED TRANSPORTATION CHARGES:- Rs. 4651692 PER MONTH. (ALWAYS CHARGED IN 1ST HALF BILL)

RLNG:-

1) GAS COST :- INDIAN Rs COMPONENT = 42.61 PER MMBTU + FECOMPONENT $6.5137 PER MMBTU (VARIABLE)

2) TRANSPORATATION CHARGES: - Rs 19.83 PER MMBTU GAS TRANSPORTED.

GAS NOMINATION AND PROCUREMENT ACTION:-

CCPP UNIT 1:- GAIL ALLOCATES APM AND RLNG GAS DAILY. WE DONT HAVE ANY CONTROL OVER ALLOCATION.

OVER DRAWL 3% IS ALLOWED PER DAY SUBJECT TO 0% OVER DRAWL IN BILLING PERIOD.

CCPP UNIT 2:- DAILY NOMINATION IS GIVEN BY OPERATION SECTION AS PER REQUIREMENT FOR 5 POINT. 1) RIL 2) RGTIL ENTRY 3) RGTIL EXIT 4) GSPL ENTRY 5) GSPL EXIT

AGAINST THIS NOMINATION RIL, RGTIL AND GSPL GIVES SCHEDULE AT ALL THIS 5 POINT.

THIS MAY BE DIFFERENT FROM NOMINATED QTY. THIS IS ACTUAL USABLE QTY.
