The organisation has so far replaced 78,452 conventional bulbs with CFLs
HYDERABAD: In the days when power conservation has become the trendiest word to mouth but not to practise, South Central Railway, with its energy saving technologies and methods, is blazing a trail in power thrift for other organisations to emulate.
Since the year 2006 when it first began to adopt clean technologies, the organisation has been able to save up to 1.92 crore units of non-traction energy which translates into Rs.9.25 crore saved by way of reduced power bills.
Beginning from about 36 lakh units in 2006-07, the energy savings increased with each passing year and stood at 62.5 lakh units during 2009-10.
Installation of intelligent lighting systems and use of alternative energy resources wherever feasible have helped to a great extent in reducing power consumption, says Chandrima Roy, Chief Public Relations Officer of SCR.
Auto lighting systems
“All the officers' chambers are equipped with automatic lighting systems. Body-heat sensors installed inside would signal illumination only when somebody enters the room,” says Ms. Roy. The same technology was adopted for passenger waiting-halls too at the Secunderabad Station. Besides, infra-red sensors are placed in seven major stations -- Secunderabad, Vikarabad, Tandur, Parli-Vaijnath, Latur Road, Udgir and Ramagundam -- to switch the lights on or off depending on the arrivals. About 70 per cent of the lights in each station are connected to the sensors in such a way that they are powered only when a train chugs in. Infra-red rays projecting onto the track would sense the obstruction and raise the signal.
In 400 other stations, timers, preset to the hours of arrivals and departures, are employed to monitor the illumination.
A Miniature Circuit Breaker enables the Assistant Station Master to operate the lights in cases of delay. These measures have resulted in power savings up to 40 percent, informed railway officials.
In line with the Clean Development Mechanism agreed upon under the Kyoto Protocol, the organisation has so far replaced a total of 78,452 conventional bulbs with CFLs. And 19,000 more are in tow.
Solar water heating
Apart from providing solar water heating systems in the retiring rooms and rest houses at 28 stations, the SCR has completely powered two remote railway stations each at Krishnammakona in Guntakal Division and Latur Road in Secunderabad Division, with solar energy.
Fifty level crossing gates over the zone are also in the process of being lit with solar energy and LED applications.
Deserving special mention is the organisation's pioneering initiative in using hybrid technology of wind and solar energy to illuminate a level crossing between Ghatnandur and Parli stations.
