Energy Auditing and Conservation for Textile industries (A Case Study: Else Addis Industrial Development P.L.C)

Abstract

The textile industry is one of the major energy-consuming industries and retains a recorded the lowest energy utilization efficiency. Energy in the textile industry is mostly used in the form of electricity as a common power source for machinery, heating and ventilating air conditioners, lighting systems, and other equipment a sufficient and reliable supply of energy is needed to develop any country in the world. However, there are problems in the conversion and usage of these energy sources, such as high energy wastage, high cost of energy to convert and use, and high carbon emissions to the environment. Most of the time, it occurs in developing countries such as Ethiopia, which has little knowledge of energy conservation and usage, which makes these developing countries generate higher energy instead of using the existing energy effectively. Industries such as textile, sugar, and cement factories consume a large amount of energy, but do not use it effectively, which results in paying extra money that affects the factory and the country in general. The ELSE Addis Industrial Development PLC uses seed cotton as input and produces lint cotton, different count yarns, and woven grey fabrics as the final product. The eighteen items identified together as energy-saving opportunities have a cumulative payback period of five months at current energy prices. These items account for expected electrical energy savings of 3,150,111.87 kwh, or 18 percent of 2023 plant energy consumption. The annual savings identified at the ELSE Addis Industrial Development PLC through a detailed energy audit indicate the potential of ETB 9,757,192.67385. The Investment required for implementing all the energy-saving opportunities is ETB 1,810,295. Most of the recommended energy conservation measures are those with simple payback periods of less than four months on an overall basis.
