d. Cost of HFO = Tk 26.00 per Litere. Heat rate to be used for weighted average of 50%, 75% and 100 % loadunder Site ConditionSo H = H 100% x 0.8 + H 75% x 0.1 + H 50% x 0.1 KJ per Kwhf. Operation and Maintenance cost, O p = Tk 0.50 per kWh + Lub oil consumptioncost per kWhg. Discount rate on capital investment - 15%(iv)Example of Financial Analysis:(1) Po = Total Net generated output at low voltage side of step-up transformer atSite Condition in kWEP 0 = Annual generated energy at low voltage side of step-up transformer in Kwh= P 0 x 24 x 365 x 0.3 KwhH = Average weighted heat rate of generating unit(100%, 75% and 50% load at Site Condition) in KJ / kWH= H 100% x 0.8+ H 75% x 0.1 + H 50% x 0.1 KJ per KwhHc = Annual heat consumption= H x EP 0 in KJFuel Calorific Value (LHV) of HFO fc = 40,450 kJ/litAnnual fuel consumption =H c / f c , Liter = F aF AC = Annual fuel cost = Tk 26.00 × F aCa = Annual operating and maintenance cost = O p x EP 0(2) A= First cost including the cost of essential spares as described in the TenderDocuments, 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= 450 days(5) C T = Capitalised cost of transformer loss= [(1+r) n –1] × t × e (P 0 +0.35 P FL )r (1+r) nwhere, C T = Capitalised cost of transformer loss in Bangladesh Takar = Discount rate, 15%n = Years of service life,15 yearst = Operating hours in a year, 8760 hourse = Cost of energy, Taka 2.38 per KwhP 0 = No load loss in KWP FL = Full load loss at ONAF condition in KWL.F.
