Previous years figures have been given in Brackets and
modified wherever necessary. The consumption per unit for steel production do not include
the energy consumption in Mines that is furnished separately under EN17.
The energy consumption at stockyards, marketing offices has also not been reported, as the
same is insignificant. (* last years reported figure of 1788 KWH for electricity & 90
litres for furnace oil are corrected now for SSL West).
EN17 ENERGY
EFFICIENCY AND RENEWABLE ENERGY INITIATIVES
No initiative has been taken to use renewable energy. In
the Steel Works (Integrated Iron & Steel Production facilities at Jamshedpur), the
specific energy consumed was 29.52 G. Joule/tonne of crude steel during 2003-2004, an
increase of 1.0% over the previous year was due to commissioning of several new facilities
in the Steel Works. At other units, the consumption of electricity and petro-fuel is also
coming down year-after-year as shown below.
 
The formula for calculation of specific energy consumption
n
 Qn
x CVn / Crude Steel Production (Tonnes)

Q = Quantity of solid, liquid & gaseous fuels
CV = Calorific Value of fuels (G.Cal/Unit) |
