Energy resources of Sri Lanka

Energy supply in Sri Lanka is mainly based on three primary sources, water, biomass and petroleum (Figure 18). In 2004, hydroelectricity production was accounted for 710 kTOE (thousand Tonnes of oil equivalent). However, the biomass energy supply was much more higher, 4513 kTOE, while a little less was supplying by crude oil, diesel and LPG (4132 kTOE). Now, it has grown up more and towards coal since the coal power plant was established at Norochcholai. Also new macro hydropower plants have been added to the system (Upper Kotmale and Kukule Ganga). Several mini hydropower plants are adding to the power sector of Sri Lanka day by day increasing the power supply. Additionally, the non-conventional power sources, mainly the pilot wind power plants supply 3.6 kTOE to the system. However, with the development, the energy demand has a growth rate of 3% annually, which is impossible to supply by the renewable resources alone and therefore we must proceed with non-renewable resources although the prices increasing.
