from a local or widespread electrical blackout; voltage reduction to effect
load curtailment and other plans which may arise. HOPEWELL shall make technical
references available concerning start-up times, Black Start capabilities, and
minimum load carrying ability, broken down into:

1. Capacity

Subject to the provisions of Clause 5.05, the capacity of the
Power Station shall not be less than 200MW at 37 (degrees) C
site conditions, as measured at the generator terminals.

2. Frequency Limitation

The frequency limitations of gas turbine set for continuous
operation shall be between the range of 58.2 Hz and 61.5 Hz.

The under frequency tripping relay shall be set at 57.5 Hz.

The gas turbine overspeed trip shall be set at 19% above
normal speed.

3. Normal Voltage

The normal voltage at the high side of the main power
transformer shall be 110 KV, plus or minus 5 percent.

4. Load Sharing Operation

At normal operation mode, except during start up and shut
down, the generating units shall be capable of being operated
as follows:

30

34

– Turbine preparation and : 15 minutes per
start up to synchronous unit
speed not less than

– Synchronizing and loading : 4 MW per minute
to full load under normal
condition, ramp increase
not greater than

In Emergency, the generating units shall be capable of being
operated as follows:

– Turbine preparation and : 8 minutes per
start up to synchronous unit
speed

– Synchronizing and loading : 12 MW per minute
to full load under normal
condition, ramp increase
not greater than

6. OPERATION MODE

The Power Station shall be utilized as a peaking plant and be
expected to operate five (5) days per week – Monday to Friday
– and shall remain on standby over the weekend and during the
ten (10) public holidays per year, except during scheduled
maintenance. The Power Station however, is expected to
operate at any other time as may be called upon by NAPOCOR
during Emergency and/or abnormal system conditions with
adequate notice having been given by NAPOCOR and would be
manned 24 hours a day.

June 25, 1989 without Forced Outage.

– Metered energy delivered on June 25, 1989 = 5,500,00 KWH

– Tested Plant Net Heat Rate = 12,300 BTU/KWH

1. Capacity Fee = (BCR*CC) (1-TFOD/Nd) – (Y*1.05)(BCR) (NC-CC)

where: BCR = $3.225/KW/month
NC = CC = 100,000 KW
TFOD = 6 days (May 26 to May 31 i.e. including
days before completion)
Nd = Total number of days = 31 days (May 26
to June 25)
Y = variable = 0

Capacity fee = ($3.225*100,000) * (1-6/31 – 0
= $322,500 * 25/31
$260,080.64

2. Energy Fee = (BER*ED) + 0 (Vg-Vt)

where: BER = $0.003/KWH plus Ps0.023/KWH
ED = 5,500,000 KWH

Energy Fee = 5,500,00 * ($0.003 + Ps0.023)
$16,500.00 plus Ps126,500.00

3. Total Bonus = $260,080.64 + $16,500.00 + Ps126,500.00
= $276,580.64 plus Ps126,500.00

II. PENALTY FOR DELAYED COMPLETION

Data and assumptions:

– lst 100 MW completion on June 1, 1989 with 5,500,000 KWH
monthly energy

– 2nd 100 MW completion on November 1, 1989 with 5,500,000 KWH
monthly energy

– Tested Plant Net Heat Rate = guaranteed 12,300 BTU/KWH

1. Billing period August 26 through
September 25, 1989, still Bonus:

CF = $3.225 x 100,000 = $322,500.00
EF = 5,500,000 x ($0.003 + Ps0.023) = $ 16,500.00
+ Ps126,500.00
————
Total Bonus = $339,000.00
+ Ps126,500.00

2. Billing period September 26 through
October 25, 1989:

CF = $3.225 x 100,000 = $322,500.00
EF = 5,500,000 x ($0.003 + Ps0.023) = $ 16,500.00
+ Ps126,500.00
————
Gross Fee = $339,000.00
+ Ps126,500.00

Penalty for period October 16 through
October 25, 1989:

Capacity penalty = $3.225 x 100,000 x 10/30 x 1.05 = $112,875.00

Total Net Billing = $226,125.00
+ Ps126,500.00

3. Billing period October 26 through
November 25, 1989:

– For lst 100 MW power & energy delivery = $339,000.00

– For 2nd 100 MW power & energy delivery

CF = $3.225 * 100,000 x 25/31 = $260,080.65
EF = 5,500,000 * (25/31) * (0.003 + Ps0.023) $ 13,306.45
+ Ps102,016.12

– Penalty for period October 16 through
October 31, 1989: = $ 67,725.00
————
– Penalty = (6/30) * $3.225 * 100,000 x 1.05

Total Net Billing = $544,662.10
+ Ps102,016.12

III. PENALTY AND LIQUIDATED DAMAGES

If no capacity of the Power Station is completed 300 days after Target
Completion Date of October 15, 1989:


1) Capacity Penalty = $3.225 * 200,000 * 12 * 300/365 = $ 6,679,725.80
2) Liquidated Damages * 1.05 = $ 4,200,000.00
————–
Total = $10,879,725.80
==============

IV. NORMAL CONDITION MONTHLY BILLING

Data and Assumptions:

Nominal Capacity = Contracted Capacity = 200,000 KW

Monthly Energy Delivery = 14,600,000 KWH

1. If no Forced Outage or scheduled Downtime


CF = BCR * CC = $ 645,000.00
= $3.225 * 200,000

EF = ED * BER = $ 43,800.00
= 14,000,600 x $0.003 + Ps0.023 + Ps 335,800.00
————–

Sub-Total = $ 668,800.00
+ Ps 335,800.00
==============

Start-up Fee:

Assume: 21 start-ups/month at 30 minutes

Energy = 3,500 KW x 0.5 x 21 = 36,750 KWH

Start-up fee = 36,750 * ($0.003 + Ps0.023) = $ 110.25
+ Ps 845.25

Total Bill = $ 688,910.25
+ Ps 336,645.25
————–

2. If during the Month, any of the units were on Forced Outage
for a total of five (5) days or that the Power Station failed
to provide 200 MW as called upon by NPC load dispatcher for a
total of five (5) times:

CF = $3.225 * 200,000 * (1-5/30) = $ 537,500.00
EF = 14,600,000 * ($0.003 + Ps0.023) = $ 43,800.00
+ Ps 335,800.00
————–
Total Bill = $ 581,300.00
+ Ps 335,800.00
==============

NOTE: Penalty = $107,500.00

69

3. If during the Month, one of the units (50,000 kW capacity)
accumulated an EOH of 4000 hours but exceeded its allowable
Downtime per the maintenance schedule:

Total no. of Downtime days = 5 days

Allowable Downtime:

Per Item 1, Schedule Six = 1/2 day
Per Item 4, Schedule Six = 3 days

Total Allowable Downtime = 3-1/2 days

Forced Outage 5 – 3/12 = 1-1/2 days

CF = ($3.225 x 200,000) (1 – 1.5/30)
= $645,000 x (1 – 0.05)
= $645,000 x 0.95
= $612,750

Penalty = $32,250

V. Penalty/Bonus due to deviation from Guaranteed Plant Net Heat Rate

Penalty Bonus = 0 (Vg-Vt)

Vt = ED * HR(g) * lLHV * 1/d

where: O = Price of fuel = $0.1524 or P3.20/litre
HR(g) = 12,300 BTU/KWH Guaranteed Plant Net Heat Rate
d = 1.85 lb/litre density of fuel
ED = 14,600,000 KWH delivered energy per month

1. If HR(t) = 12,546 BTU/KWH as tested at Commissioning Date

then:

Vg = 14,600,000 x 12,300 x 1/18,400 x 1/1.85
= 5,275,558.167 litres/month

Vt = 14,600,000 * 12,546 * 1/18,400 * 1/1.85
= 5,381,069.33 litres/month

Thus, for the lst 6,000 EOH (more or less one year operation)

(Penalty/month = 0 (Vg-Vt)
= $0.1524 (5,275,558.167 – 5,381,069.33)
= $16,079.89/month

66
70

2. If HR(t) = 12,054 BTU/KWH as tested at Commissioning Date

then:

Vt = 14,600,000 x 12,054 x 1/18,400 x 1/1.85
= 5,170,047.004 litres/month

Thus, for the lst 6,000 EOH (more or less one year operation)

Bonus/month = $0.1524 (5,275,558.167 – 5,170,047.004)

= $16,079.89/month

3. If HR(t) = 12,669 BTU/KWH as tested after 6,000 EOH
(more or less 2nd year)

then:

HR(g) = 12,300 * 1.006 = 12,373 BTU/KWH
V(g) = 14,600,000 * 12,373 * 1/18,400 * 1/1.85
= 5,306,868.2 litres/month

Thus, for the 2nd 6,000 EOH (2nd year operation)

Penalty/month = $0.1524 (5,306,868.2 – 5,433,824.8)
= $19,348.18/month

4. If HR(t) = 12,263 BTU/KWH as tested after 6,000 EOH (more or
less 2nd year)

then:

V(t) = 14,600,000 * 12,263 * 1/18,400 * 1/1.85
= 5,259,688.5 litres/month

Bonus/month = $0.1524 (5,306,868.2 – 5,259,688.5)
= $ 7,190.18/month
