2,640 MW of electricity can be saved through efficient devices

DHAKA : Some 2,640 MW of electricity can be saved from the current use of 7,650 MW through efficient devices and equipment, said a study, reports UNB.
The study has been conducted by the Power Division. Power Division’s Joint Secretary Siddique Zobair carried out the study as part of the government move to improve efficiency in power sector.
The study found that there is a potential for saving of 1020 MW of electricity from residential and commercial uses. Currently, the residential and commercial lights, particularly the bulbs, consume 1700 MW of the country’s total electricity.
But if the conventional and CFL bulbs in residences and offices are replaced with the LED bulbs, the power consumption will come down significantly as LED bulbs consume much less electricity than any other bulbs.
The LED lamp is a light-emitting diode (LED) product that is assembled into a lamp (or light bulb) for use in lighting fixtures. LED lamps have a lifespan and electrical efficiency that is several times better than incandescent lamps, and significantly better than most fluorescent lamps, with some chips able to emit more than 100 lumens per watt, said experts.
Siddique Zobair said sometimes LED bulbs consume only 12 percent electricity to provide 100 percent light of an incandescent lamp or conventional bulb.
The study said about 30 MW load could be saved from tube-lights from the existing 120 MW of their consumption if their ballasts are replaced with improved ones.
The study found that fans used in residences, offices and other places are consuming 1300 MW of electricity. But this consumption is possible to bring down to 780 MW by using efficient fans through replacement of the existing ones. In that case, 520 MW of electricity will be saved.
Siddique Zobair said the existing fans normally consume 80-100 watt of electricity. But now efficient fan was invented and these fans consume 60 watt of electricity.
