Delhi Metro Rail Corporation (DMRC)The Delhi Metro Rail Corporation (DMRC) was conferred an award on 14-12-2008 by the power ministry for adopting special measures that result in energy conservation. Satish Kumar, DMRC's director (electrical), received the award on behalf of DMRC from Power Minister Sushil Kumar Shinde at the National Energy Conservation Awards function held at the Hyatt Hotel in the capital.

The measures that were lauded by the ministry included utilisation of energy regenerated during braking the trains for air conditioning and lighting, management of lighting in stations and tunnels, use of solar energy in parking lots, and optimisation of air conditioning in trains and stations. DMRC has been previously given ISO 14001 and OHSAS 18001 certifications for good environmental management and has also been recognised by the United Nations as the first railway project to earn carbon credits.

DMRC officials explained that under the regenerative braking system, whenever a train applies brakes, the kinetic energy released starts a machine known as converter-inverter. Then this machine acts as an electricity generator, which supplies electrical energy back to the over head electricity lines. The regenerated electrical energy that is supplied back to the over head electricity is used by other accelerating trains on the same service line, thus saving overall energy in the system as about 30 per cent electricity requirement is reduced.

“At DMRC, energy conservation and efficiency by adopting best practices are encouraged. Keeping in mind the huge loan that we have to repay, efforts are made to conserve wherever and whenever we can.” said Anuj Dayal, Chief Public Relations Officer of DMRC.

DMRC is also working on a project to claim carbon credits for modal shift of commuters from buses/cars to the metro railway as tail-end emissions of such vehicles contribute to global warming. It has also made arrangements to harvest rainwater at all stations in Phase II and on Line 3 of Phase I.
