Example of Financial Analysis on Natural Gas:
(Analysis will be made on both HSD and Natural Gas)
(1) Po = Total Net generated output at generator terminals at Site Condition in kW
EP 0 = Annual generated energy at generator terminals in Kwh
= P 0 x 24 x 365 x 0.3 Kwh
H = Average weighted heat rate of generating unit
(100%, 75% and 50% load at Site Condition) in KJ / kWH
= H 100% x 0.7 + H 75% x 0.2 + H 50% x 0.1 KJ per Kwh
Hc = Annual heat consumption
= H x EP 0 in KJ
Fuel Calorific Value (LHV) of Gas fc = 35,350 kJ/Nm 3
Annual fuel consumption =H c / f c , Nm 3 = F a
F AC = Annual fuel cost = Tk 2.82 × F a
Ca = Annual operating and maintenance cost = Tk 0.20 x EP 0
(2) A= First cost including the cost of essential spares as described in the Tender
Documents, converted into Taka by applying the Exchange Rate as specified.
(3) d = Discount rate
= 15% per annum
(4) D= Estimated weighted days for completion of the power plant
= 600 days
MD = Monetization for each day of late commissioning of the power plant
= 0.1% of Tender price (first cost) per day
Total Monetization, M = MD x (D1- D)
= MD x (D1 - 600)
(5) C T = Capitalised cost of transformer loss
= [(1+r) n –1] × t × e (P 0 +0.44 P FL )
r (1+r) n
where, C T = Capitalised cost of transformer loss in Bangladesh Taka
r = Discount rate, 15%
n = Years of service life,15 years
t = Operating hours in a year, 8760 hours
e = Cost of energy, Taka 2.38 per Kwh
P 0 = No load loss in KW
P FL = Full load loss at ONAF condition in KW
