State-run BHEL on Friday flagged off India’s first electric locomotive with a regenerative system for Indian Railways, it said. The regenerative technology helps avoid loss of heat energy when brakes are applied and feeds the energy back to the overhead power lines.

More Information:

  • A company statement said, BHEL has developed a state-of-the-art regeneration system through in-house R&D efforts for Indian Railways’ fleet of conventional electric locomotives.
  • It added that the country’s first such regenerative 5,000 HP WAG-7 electric locomotive was flagged off from the company’s Jhansi plant.
  • The idea of developing the energy-efficient regeneration system was mooted by Indian Railways and BHEL responded to it by successfully developing the technology in-house, giving an impetus to the ‘Make in India’ initiative.
  • Currently, Indian Railways’ electric locomotives have a dynamic braking system where the energy generated during application of brakes gets wasted in the form of heat.
  • BHEL has developed a system introducing the regenerative braking concept in these locomotives, that will feed the energy back to the overhead power lines.
  • This will result in significant saving in energy consumption.
  • BHEL is the first organisation to successfully demonstrate the concept of regenerative braking system for DC traction motor driven conventional electric locomotives.
