Life Cycle Cost Analysis (LCCA) is used for project profitability analysis because it takes into account the entire life of a project and time value of money.

Project Profitability Analysis

Fuel required per trip =2000L (Approximately)

For Electricity Generation Purpose,

Fuel required/day = 4.5L

For 10 days,

Fuel required/trip=4.5*10

=45L

Fuel cost per trip =45L*65Taka

= 2925 Taka

If we consider minimum 10 trip in a year, then fuel cost in a year = (2925*10)Taka

=29,250 Taka

Cost For Produce Electricity Present System

19

Continue…

Battery cost per year = (2*10000) Taka

=20,000 Taka

Incandescent Bulbs cost per trip = 240 Taka

Incandescent Bulbs cost per year = (240*10) Taka

=2400 Taka

Dynamo cost= 25000Taka

Dynamo Sustainability=5Year

Total Initial cost for power purpose is =29250+20000+2400+25000 Taka

= 76,650 Taka

Total cost for power purpose from 2nd to 4th year is=51,650 Taka

Total cost for power purpose at 5, 10 and 15 year is=76,650 Taka
