Year : 2010-11 - CCL

ANNUAL REPORT 2010-11 ________________________________________________________
present, all efforts have been made in your
Company for using energy more efficiently and
judiciously.
Conservation is only possible by creating
awareness at all levels and adopting conservation
measures. Thus for creating awareness, energy
conservation meetings were organized amongst
the employees during the year 2010-11.
All efforts have been made to improve
specific consumption of Power, HSD & Lubricant
which are the basic input for production purpose.
There has been improvement in specific
consumption of Power during the year 2010-11.
However, there is a marginal increase in specific
consumption of HSD & Lubricant, though absolute
consumption is less. The main reason is increase
in haul road length as well as depth of the mines.
The following table depicts the Specific Energy
Consumption values for the year 2010-11, with
respect to the year 2009-10:
Specific Consumption* 2010-2011 2009-2010
POWER kWh/CuM 5.645 6.129
HSD Ltrs./CuM 0.935 0.910
Lubricant Ltrs./CuM 0.043 0.035
* The computation of specific power consumption also includes the
power consumed in service units of the Areas and composite product
of UGs & OCPs. The computation of specific consumption of POL
is only for opencast projects of the Company.
Tentative benchmarking for HSD of 14 Open
Cast Mines of CCL have been carried out by
CMPDIL. Detailed reports on HSD consumption
audit and bench-marking of Jharkhand, Kathara,
Ashoka & Birsa opencast mines have also been
carried out by CMPDIL. Specific consumption of
HSD for all the 14 Opencast mines is being
monitored every month and performance is being
placed in CMDs meet for review.
