Soon, even a power grid failure would not be able to disrupt metro rail services with the Delhi Metro Rail Corporation (DMRC) going to tap power from the sun to generate electricity.
Apart from tapping solar power, the DMRC will regenerate power achieved through renewable sources of energy with the introduction of advanced regenerative braking technology.
According to Delhi Metro, the new trains that will be added to the fleet in phase 3 will regenerate at least 60 per cent power. Delhi Metro will further reduce its dependency on power from non-renewable sources of energy by generating solar power to run the service that caters to two million commuters daily.
“In six months time, we will start generating solar power, which would be used for running train services. However, the quantum of power generated is yet to be ascertained,” said a DMRC official.
DMRC currently requires about 140 MW power to run the show. Now, it plans to shift dependency on solar power to a huge extent.
Solar power would be initially generated through two stations and a depot and later at many phase 3 stations and depots, said a DMRC official.
The DMRC plans to harness solar energy at elevated metro stations, in depots and in open areas at metro stations. Based on the success of the initiative, DMRC will add generation capacity for its phase 3 structures.
“With technical support from a German company, German International Cooperation (GIZ), we are going to install solar panels at the Yamuna Bank metro station, Dwarka sector 21 and Yamuna Bank metro depot within six months,” said Anuj Dayal, DMRC spokesperson. Last month, DMRC has signed an MoU with GIZ, he said. GIZ provides consultancy to ministry of environment and forest (MoEF) for many projects.
Delhi Metro recently has formed an in-house team headed by Satish Kumar, director (electrical), to execute the project. The team, sources said, is now preparing the tender documents, which will be floated in a couple of months.
“Once we start generating requisite power, service disruption due to power failure or incidents such as recent grid failure affecting services would be a matter of past,” said an official.
