05 Miscellaneous Charges in Lacs 10

06 Total Project Cost in Lacs 1815.00

07 Annual Power generation (mw x 0.9 x 24 x 330) Units 42768000

08 Power Plant Self Consumption in Units 5132160

09 Power available in downstream in Units 37635840

10 Fuel Requirement in Tones/annum See Break-up

11 Variable Cost (Fuel Cost) Rs750/Tonne in crores See Break-up

12 Fixed Cost (O & M 2.0% of project cost,Interest charges 10%,Depreciation 7.0%,Overheads and others) in crores

Unit Cost of Power Generation In Rupees [100% Husk] =1.71

Unit Cost of Power Generation In Rupees [100% Bagasse] =2.04

Unit Cost of Power Generation In Rupees [50% Husk + 50% Bagasse]=1.88

BREAK UP

i) ANNUAL POWER GENERATION: -

(Capacity (Mw) X Loading Factor X Hours X Shifts in Annum) x 1000= 6 x 0.9 x 24 x 330 x 1000 = 42768000 Units.

ii) POWER PLANT SELF-CONSUMPTION: -

(Mw) X 12% Consumption X Loading Factor X Hours X Shift in Annum X 1000= 6 x 0.12 x 0.9 x 24 x 330 x 1000 = 5132160 Units.

iii) POWER AVAILABLE IN DOWN STREAM: -

Annual Power Generation - Power Plant Self consumption. = 37635840 Units.

iv) FUEL REQUIREMENT: -

As Per Design = Qty Kg/Hr. => Qty x 24 x 330 = Qty Tonnes / Annum1000

v) VARIABLE COST (FUEL COST): -

=> Rs./T x Qty = Crs (Husk cost = Rs. 500/Ton).106 (Bagasse cost = Rs. 500/Ton).

100% Husk =7786 Kg/Hr = 61665 T/Annum= 3.08 Crs.100% Bagasse =10966 Kg/Hr = 86850 T/Annum=4.34Crs.50% Husk =3893 Kg/Hr = 30833 T/Annum=1.54 Crs.50% Bagasse =5483 Kg/Hr = 43425 T/Annum=2.17 Crs.

vi) FIXED COST: -

O & M [2.0 % project cost] => 1815 X 0.020 = 36.30Interest [10 % of project cost] => 1815 X 0.10 = 181.50Depreciation [5 % of project cost] => 1815 X 0.05 = 90.75Overheads & Others [1.5 % of project cost] => 1815 x 0.015 = 27.22

335.77 Lakhs = 3.36 Cr

vii) UNIT COST OF POWER GENERATION: -

= Variable cost + Fixed cost Power Available at Downstream

FUEL QUANTITY REQUIREMENT FOR 30 TPH BOILER

BOILER CAPACITY =30000 kg/hr.

Husk GCV =3200 kcal/hr.

Bagasse GCV =2272 Kcal/hr

Feed Water Temp in Deg.C =130

[1] HUSK REQUIREMENT =(Boiler Capacity X (Steam h1- Feed Water h2) Efficiency X GCV of Husk

= 30000 X (811-130) 0.82 X 3200

= 7786 KG/HR

[2] BAGASSE REQUIREMENT=(Boiler Capacity X (Steam h1- Feed Water h2) Efficiency X GCV of Bagasse

Results:

100% Husk = 7786 Kg/Hr

100% Bagasse = 10966 Kg/Hr

50% Husk = 3893 Kg/Hr

50% Bagasse = 5483 Kg/Hr
