Solar energy to power 4 Metro stations in Hyderabad
The entire HMR project has the capacity of facilitating generation of 20 million units of clean energy a year.
Hyderabad: When the Hyderabad Metro Rail commences its commercial operations on the Miyapur-Nagole stretch from November 28, the four Metro stations at Nagole, Uppal, Uppal Stadium and Miyapur will have a distinction.
The Hyderabad Metro Rail Limited (HMRL), with the objective of promoting green and clean energy usage, has installed solar panels on the rooftops of these four stations to generate solar energy. Among the 24 stations on the Miyapur to Nagole stretch, these four stations will be utilising solar energy for various purposes.
HMRL authorities informed that nearly 2,500 units of clean energy will be generated per day through the solar panels installed on the roof tops of the four stations. However, the energy generated will be utilised only for certain utilities, said a senior official from HMR.
During the recently conducted Urban Mobility India conference here in the city, experts had strongly pitched for usage of clean and eco-friendly energy. HMRL had made plans for usage of solar energy from the inception stage of the project. For this, they had conducted a survey and identified 54,586 square metres of rooftop area on stations, depots and 33.2 acres on ground in depots. This space would facilitate in generating clean and eco-friendly energy to the tune of 15 MW.
The entire HMR project has the capacity of facilitating generation of 20 million units of clean energy a year. This will account for nearly 10 per cent of the total energy requirement of HMR and more importantly, will aid in reducing the carbon emission by 16,000 tonnes a year compared to the use of conventional energy sources, explained the official.
Other metro services in the country, including Chennai and Delhi too are focusing on usage of solar energy in a big way.
DMRC aims at generating 20 MW solar power
Delhi Metro Rail Corporation (DMRC) has set itself an ambitious target of meeting 20 MW of generating power through solar energy by next one year. Of the target, already 7.2 MW has already been achieved and is being used for meeting commuter facilitation load on the DMRC premises.
Further, DMRC aims at generating 31 MWp of solar power by March 2018. As per its solar policy, DRMC also plans to generate 50 MWp of solar power by the year 2021. Under its Clean Development Mechanism project, DMRC is also helping other metros in reducing carbon emissions from their operations.
HMR’s 30 km stretch will require 60 MW per day
Hyderabad: The 30 km stretch on which the Hyderabad Metro Rail (HMR) will be operating after its late November launch will require about 60 MW power supply a day.
HMR will be getting this power supply from four exclusive Receiving Sub Stations (RSS) at Uppal, Yousufguda, Miyapur and Mahatma Gandhi Bus station (MGBS). The power is generally used for the traction system (train services), for auxiliary services at stations and depots and for malls and commercial establishments at the Metro stations.
HMR is adopting a 25KV AC electrical system, generally used for railway electrification systems worldwide, for the operations and the project is fed by a 133 KV incoming power supply from the TS Grid for all the four Receiving Sub Stations. Every Metro Rail station will also have an auxiliary substation, which is compact and adheres to international standards in construction, officials said.
These auxiliary substations have also been installed in depots and the Operation Control Centre for providing a 33kv power supply for signals, communications, escalators, lifts, air conditioners, automatic fare collection equipments, gates, station lighting and fire protection systems among other uses.
The switching operations are done through the remote control from the Supervisory Control and Data Acquisition (SCADA) system at the Operations Control Centre (OCC) at the Uppal depot.
