STATEMENT  REFERRED  TO  IN  REPLY  TO  PARTS  (a)  TO  (e)  OF UNSTARRED  QUESTION  NO.  2690  BY  SHRI  P.P.  CHAUDHARY  AND SHRI  KAUSHAL  KISHORE  TO  BE  ANSWERED  IN  LOK  SABHA  ON 10.03.2021 REGARDING ENERGY CONSERVATION

- (a)  to  (c)  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. Railways has introduced Insulated-Gate Bipolar Transistor (IGBT) based  3-phase  propulsion  system  with  regenerative  braking  in Electrical Multiple Unit (EMU) trains, Mainline Electrical Multiple Unit  (MEMU),  Kolkata  Metro  rakes  and  Electric  Train  Sets  to conserve energy during the operations.
- ii. Production Units have completely switched over to production of energy  efficient  three-phase  electric  locos  with  regenerative features.
- iii. Provision of energy efficient Light Emitting Diode (LED) lighting in Railway installations including Railway stations, service buildings, Residential quarters, coaches, EMUs/MEMUs for reduction in electricity consumption.
- iv. Use  of  energy  efficient  Brushless  Direct  Current  (BLDC)  motor fans in coaches.
- v. Introduction  of  Head  On  Generation  (HOG)  system  in  trains  to reduce  diesel  fuel  consumption  in  power  cars.  1012  electric locomotives are equipped with hotel load converters.
- vi.
- vii.
- Regular energy audits at consumption points.
- Emphasis on use of 5 Star rated electrical equipments.
- viii. 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 15 minutes.

- ix. Trailing  locomotives  of  multi  units  (MU)  hauling  light  loads  are switched off to save energy.
- x. 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.
- xi. Monitoring  the  fuel  consumption  with  respect  to  trip  ration  of diesel locomotive drivers.
- xii. Auxiliary  Power  Unit  (APU)  has  been  provided  in  1167  diesel locomotives to reduce fuel consumption when locomotive is idle.
- xiii. Monitoring of idling of diesel locomotives is being done through remote  monitoring  and  management  of  Locomotives  and  trains (called as REMMLOT). 3760 locomotives at present are equipped with REMMLOT.
- xiv. Use of 5% bio-diesel in  traction  fuel-Blending  of  bio-diesel  with High Speed Diesel (HSD) to the extent of 5 % to save HSD.
- xv. 20% Compressed Natural Gas (CNG) substitution in DEMUs-CNG usage  emits  less  Greenhouse  Gases  (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.
8. (d)  and  (e)  Ministry  of  Railways  has  entered  into  Memorandum  of Understanding (MoU) with Department for International Development (Government  of  United  Kingdom)  now  Foreign  Commonwealth  & Development Office (FCDO) for collaboration on energy and sustainability. Further, an MoU has also been signed with Confederation of Indian Industries (CII) for energy efficiency improvement and conservation of energy.
