DMRC starts work on Substations for Greater Noida Metro

dmrc substationGreater Noida: The Delhi Metro Rail Corporation (DMRC) on Saturday laid the foundation for the first of the two receiving sub-stations (RSS) along the Noida-Greater Noida Metro corridor. This is the first step in the setting up of the substations which will supply power for stations and trains along the route.

These receiving substations will cater to the energy needs of the 29.9km Metro corridor. The station, which will come at a cost of Rs 100 crore, will be located in sectors 148 and 83. The work is expected to be completed by December 2016.

According to DMRC officials, reliable electricity supply is a critical requirement for operating the Metro network. The RSS convert electric power to an appropriate voltage and frequency for the Metro to operate. The two RSS will be constructed by DMRC and the work contract has been awarded to Siemens (India).

“At both the RSS, incoming power supply at 132kV voltage level will be taken from the grid substation of the state electricity board, that is, Uttar Pradesh Transmission Corporation, and will be stepped down to 25kV for traction (train operation) purpose and 33kV for power to feed station loads, like lighting, airconditioning, lifts, escalators, etc,” said Anoop Kumar Gupta, director electrical, DMRC.

Officials further said these RSS would be provided with state-of-the-art gas-insulated systems (GIS) and would be fully automated. They will have a series of eco-friendly features, like solar power panels, LED bulbs, carbon dioxide sensors and a rainwater harvesting system, officials said. There is also a proposal for the substations to generate their own power for their lighting and airconditioning needs.

“The building area for the two RSS has been optimised, with multistorey control building having a sleek and elegant look. The total land requirement has also been reduced to 2000 square metres, which is only 25% of the area required for a conventional receiving substation,” Gupta said.

“The substation buildings will be provided with green features like solar panels, rainwater harvesting, sewage water recycling, etc. Efforts will be made to get IGBC green certification for these buildings,” he said. “We will save energy between 15-20% and also help preserve the environment,” he said.

The DMRC has also proposed large-scale utilisation of solar energy along the track. All 21 Metro stations on the route will be environment-friendly, and the depot will also be equipped with solar panels, officials said. Work on the route, which is estimated to cost Rs 5,526 crore, is likely to be completed by March 2018. However, officials said that the Metro will roll much before that with trials expected to take off in December 2017.
