LED bulbs to save energy and money
It is estimated about 700,000 light bulbs lighting about 140,000 homes across the country. Every day, these 700,000 bulbs consume about 168,000 units of energy worth Nu 390,000. According to the Department of Renewable Energy under the Ministry of Economic Affairs, the problem with these incandescent bulbs is that they are 6 times less efficient than Light Emitting Diodes (LEDs).
That is where the LED bulbs come as perfect solution to be more energy efficient while not compromising the lumen requirements. If we can replace all these 700,000 incandescent lamps, the Country can enjoy annual gross energy saving of about 61.320 million units worth Nu 142.00 Million. Recognizing these potential benefits, the Department aims to replace all these incandescent lamps by energy efficient LEDs in the Country by demonstrating tangible benefits through pilot programs and creating conducive markets for supply and use. With financial support from the Government of Norway under Energy Plus Programme, the Department of Renewable Energy will replace about 26,500 incandescent bulbs by the efficient LED bulbs to begin with at the cost of Nu 4.700 Million.
At the launch of the program held at Changjiji Children’s Park, the Economic Affairs Minister said that the intention is to demonstrate to the public the benefits of energy efficiency and gradually to phase out the inefficient incandescent bulbs. “Once the benefits of the LED bulbs are demonstrated, the market force will pick up. There will be demand and so will be the supply”,Lyonpo said.
These bulbs will be distributed through the outlets of the Food Corporation of Bhutan Limited on a highly subsidized rate of Nu 100 per bulb against the market price of over Nu 300–Nu 700 per bulb depending upon the brand. Out of 26,506 LED bulbs, 23,840 LED bulbs will be for residential use and 2,666 lights for public institutions where significant energy saving potential exists. All domestic consumers will be entitled to a maximum of four bulbs on firstcome-first-served basis till the stock lasts. The interested consumers will need to bring a copy of latest electricity bill issued by Bhutan Power Corporation Limited (BPC) and citizenship identity card for verification.
With this distribution, at the national level, the annual saving is estimated at about 2 million units of energy and consequently earn additional fund of Nu 4.64 million at the average domestic tariff price of Nu 2.32per unit or earn INR 4.50 Million if exported. The investment can be recovered within one year and these benefits can be sustained for at least 20 years as these bulbs last over 20 years.
At individual consumer level, the replacement of one 60W incandescent bulb can save about 75 units of electricity per annum thereby saving Nu 173per annum per bulb. By providing maximum of 4 LED bulbs per consumer, each individual consumer can enjoy annual saving of300 units of electricity and thus save around Nu 700 per annum. Since these bulbs last more about 20 years, the consumers can enjoy energy saving of worth Nu 14,000 before they are being replaced. At the subsidized rate of Nu 100, the consumer will recoup the investment within 7 months.
