Abstract: Energy efficiency in Sri Lankan SMEs in industrial sector is typically low with a large untapped potential for energy saving. This study focused on analysing the energy saving potential of the selected SMEs in Sri Lanka. Comprehensive energy audits were conducted for five SMEs in energy intensive industrial sectors. Results showed that incorrect power factor adjustments, poor practice of switch off policy on lights and fans, inadequate modifications on lighting systems, compressed air systems, boilers, and machinery were the most significant factors led to energy inefficiencies. Further, if prompt actions were to be taken for the above issue, the study estimated that the total energy saving potential for the selected firms would be about 20% to 30% of the total energy consumption. Moreover, it was about 10% to 15% of energy costs of the selected firms. The study concludes that SMEs should focus on rectifying inefficient usage of energy.
