Energy Efficient Indian Railways

Indian Railways (IR) is committed to take new steps for energy conservation and to increase energy efficiency. Some of the measures taken are as follows:

i) Use of energy efficient 3-Phase technology with regenerative features for electric locomotives, Mainline Electrical Multiple Units (MEMUs), Electrical Multiple Units (EMUs), train sets for better energy efficiency.

ii) Introduction of Head On Generation (HOG) system in trains to reduce diesel fuel consumption in power cars. 350 electric locomotives are equipped with hotel load converters.

iii) Provision of energy efficient Light Emitting Diode (LED) lighting in all Railway installations including Railway stations, service buildings, Residential quarters & coaches for reduction in electricity consumption.

iv) Regular energy audits at consumption points - Energy Efficiency studies of six (6) Production Units (PUs) and four (4) Workshops were conducted and upto 15% energy efficiency improvement achieved. This included activities like identification of significant energy saving opportunities, one day training program, identification of potential technology suppliers who can offer energy saving technologies to the units etc.

v) Emphasis on use of 5 Star rated electrical equipments.

vi) Regular training of Loco pilots for use of coasting, regenerative braking features and switching off blowers of electric- locos in case yard detention is more than 50 minutes. Similarly, diesel locos are also shut down, if expected detention is more than 30 minutes and thereby resulting in reduction of Green House Gases (GHG) emissions.

vii) Trailing locomotive of multi units (MU) hauling empty freight trains are switched off to save energy.

viii) Energy consumption on electric locomotives is regularly monitored through microprocessor based energy meters provided in all the electric locomotives and benchmarking is done based on average energy consumption.

ix) Monitoring the fuel consumption with respect to trip ration of diesel locomotive drivers.

x) Auxiliary Power Unit (APU) has been provided in 986 diesel locomotives to reduce fuel consumption when locomotive is idle.

xi) Monitoring of idling of diesel locomotives is being done through remote monitoring and management of Locomotives and trains (called as REMMLOT). 2606 locomotives at present are equipped with REMMLOT.

xii) Use of 5% bio-diesel in traction fuel- Blending of bio-diesel with HSD, to the extent of 5%, to save HSD.

xiii) 20% Compressed Natural Gas (CNG) substitution in DEMUs -CNG usage emits less GHG than liquid fuels. Indian Railways have the distinction of being the only railway in the world to be using CNG run power cars for passenger transportation. IR has also started conversion of DEMU Driving Power Car (DPC) into dual fuel mode DEMU/DPC with CNG. 25 numbers of DPCs have been converted and are under operation.

This information was given by the Minister of Railways and Commerce & Industry, Shri Piyush Goyal in a written reply to a question in Lok Sabha today.
