Tata Steel adopts a precautionary approach to the opportunities and challenges faced across the globe while focusing on utilising resources and waste, minimising energy consumption and reducing emissions. In the area of energy efficiency it supports the development and shortlisting of positive technologies under bilateral initiatives between India and Japan, besides engaging with academic & research institutions like the Indian Institute of Technology, Kharagpur, Indian Institute of Science, University of Sheffield etc. Collaboratively, the Company studies and works on related projects to address Climate Change issues.

Tata Steel is also a part of an effort initiated by the Government of India, led by Indian Institute of Technology, to develop an energy efficiency roadmap for the country.

Tata Steel's energy efficiency programmes focus on three principal areas:

  1. Energy conservation & recovery of waste heat and energy from the processes
  2. Process efficiency enhancements through installation of energy efficient processes & technologies like TRT at G, H & I Blast Furnaces, Coal Dry Quenching (CDQ) at Coke Oven Battery No.5, 6 & 7 etc.
  3. Cost control

Some specific energy conservation initiatives:

  • As part of its commitment to produce energy efficient products, Tata Steel invests its best efforts to mitigate GHG emissions through the supply of energy-efficient steel and by-products as well as solutions proposed for construction material.
  • Steps are being taken towards efficient use of captive raw materials, the development of new technologies to enable the use of low-grade raw materials and driving greater energy efficiency and the use of alternative energy sources.
  • The Coal Mines at Jharia and West Bokaro generate the majority of their power needs from coal rejects, allowing them to continuously improve their economic performance and the environmental sustainability of their operations.
  • Initiatives have been taken at Hooghly Met Coke to reduce Electricity consumption through energy efficiency and introduction of renewable energy based lighting during 2012-13.
  • A rooftop Solar PV of 1 KW for the office and road lighting with LED lights to reduce electricity consumption by 4 KW were installed at the Jamshedpur Steel Works.
  • Electricity savings have led to a reduction in energy consumption by 358000 KCal/tonne of chromite agglomerates per annum.
  • Innovative projects implemented at the Joda East Iron Mine to conserve energy include up-gradation of the primary crusher for wet and dry processing, modernisation of the belt conveyor drive to install a VVVF drive, reduction in the loading time from about three hours to just over an hour and replacement of standard motors with energy efficient motors.
  • A significant move forward towards low carbon energy installations as well as energy efficient processes was taken through the 9.7 MTPA brownfield expansion project. This led to a drop in the overall energy consumption from 6.088 Gcal/tcs in 2011-12 to 6.083 Gcal/tcs in 2012-2013. The completion of this project has put Tata Steel firmly on its path to meeting its goals of adding new eco-efficient products to its portfolio while using fewer natural resources, less energy and less water per tonne of steel produced.
  • At Jamshedpur Steel Works, energy efficient processes, such as, power generation using Top gas pressure Recovery Turbine (TRT), ramping up Steam Recovery from Coke Dry Quenching, use of L.D. Gas, and enhanced CO Gas recovery has led to a significant reduction in energy consumption.
  • High-performance energy-efficient steel manufactured by Tata Steel enables downstream consumers to reduce the quantity of steel in applications, thereby reducing the overall energy consumption.
  • The resource and energy efficient 3.05 MTPA ā€œIā€ Blast Furnace, blown-in during 2012-13, produces Iron in a Lean Carbon manner and is aimed at attainment of higher energy reduction and efficiency.
