Generator Maintenance

I would like to inform you the diesel generator maintenance cost , from the very beginning we found, our Generator has created too much high temperature. Some times Generator has shut off. For that reason, we informed your Engineers to solve this problem but they are unavailing to find out the problem and solve it. Several times our production has hampered. In front of your Engineers we have opened our Generator Heat Exchanger and we’ve found a big size (2.2”X2.2”) round metal pc. GETCO Engineer also agrees with us that this is the main problem for high temperature and also manufacturing fault.

 Generator Maintenance Proposal

 With due respect would like to inform you that our Generator (GAS) have to servicing after every 1000 hours and also lube oil change. For this reason in next Friday January 21, 2010. from 01.00 pm. to 7.00 pm. want to set for servicing the Generator.  So, with beg most respectfully that you will give the permission for servicing the Generator on the above date and time.

  • Total Cost per Month for Generator = 18, 70,444 Tk.
  • Total Cost per Year for Generator = (18, 70,444×12) Tk. = 2, 24, 45,328 Tk.
  • Total Cost per Day for Generator = (2, 24, 45,328÷365) Tk. = 61,494 Tk.
  • Total Cost per Hour for Generator = (61,494÷24) Tk. = 2,562 Tk.

Generation Per Day (Average):

  • Old Caterpillar Gas Generator = 12 MW
  • New Caterpillar Gas Generator = 12 MW
  • Total Generation per Day = (12+12) MW

= 24 MW

= (24×1,000) KW

= 24,000 KW

  • Total Generation per Month = (24,000×28) KW

= 6, 72,000 KW

  • Per KWH Cost = (18, 70,444÷6, 72,000) Tk.

= 2.78 Tk.
