The peak electricity demand in Sri Lanka, characterised by residential lighting, occurs in the evening. Incandescent Filament Lamp (IFL) is one of the main lighting sources of 76% of residential consumers in the lower tariff block (<90 kWh/month). These Customers also receive heavily subsidised electricity. Compared with IFLs, LEDs are more efficient, but costlier. Therefore it is difficult to coax customers to replace IFLs with LEDs. Hence, a LED Lamps distribution scheme named “Shakthi” has been developed. Under this scheme, it is expected to carry out bulk purchase of LED lamps by utilities, and to supply LEDs at a price less than 1/3 rd of the market price. The investment payback is four months. Provision of low priced LEDs, on a 2 year loan scheme has been chosen as a lighting market transformation tool, to rid the grid of IFLs. 10 million LEDs (9 W) will be disseminated among 3.9 million households, which will reduce the peak demand by 304 MW, saving 432 GWh and 297,907 t CO 2 annually.
Cabinet approval has been obtained for the project and procurement activities are currently under way. The PTF on EDSM has designed a leaflet for making awareness among the people and android app has been developed in collaboration with LECO.
