LED bulbs to save en­ergy and money

Bhutan Times - - Home - Staff Reporter

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.
