IR goes 'green' with eco-friendly project for energy regeneration
New Delhi, Jun 30 : Indian Railways has reached a new milestone by approving a new green energy project in Mumbai, which can regenerate about 25 to 30 per cent of electrical energy used.
According to an official release issued here today, the Ministry of Railways has decided to replace the existing Electrical Multiple Units (EMUs) with the new ones fitted with regenerative brakes, by adopting a three-phase technology with Insulated Gate Bi-polar Transistor (IGBT) system.
Forty seven (12 car) rakes have been commissioned with regenerative braking system so far and more 48 rakes were expected to be commissioned during 2009-10, the release said.
The Designated National Authority (DNA), under the Ministry of Environment and Forests had accorded host country approval for this project under Clean Development Mechanism (CDM) on January 12, 2009.
World Bank was working for registration of this project with United Nations Framework Convention on Climate Change (UNFCCC).
The purpose of the project was to adopt a three-phase IGBT technology in Indian Railways for three phase EMUs in Mumbai suburban area of Western and Central Railways.
The technology would be used for passenger trains, which have the ability to draw electricity from the Over Head Equipment (OHE) and regenerate energy during braking.
The regenerative braking feature essentially makes use of the kinetic energy that is normally lost upon braking, which can be up to 30 per cent of one train energy requirement and converts it to reusable electrical energy, thus saving on the energy input required to operate other EMU trains running in the section.
The regenerated electrical energy reduces the consumption of equivalent grid electrical energy required by the powering train, thereby conserving electrical energy and subsequently leading to reductions in Green House Gases (GHG).
The project activity would result in reduced total energy consumption and availability of additional power at the western grid level (Western and Central Railways in Mumbai) and would lead to power being available for other economic activities in the region.
Reduced carbon dioxide emission would result in reduced global warming, a world wide concern, the release added.
