Energy is one of the major drivers for the economic development of any country. In order to reduce energy consumptions for sustainable development, continuous energy audit of industrial machines become necessary. Energy audit is one of the most comprehensive methods in achieving energy savings in industry and thus reducing excessive energy consumption. This paper analyzes energy auditing in power system in order to identify the sources of energy waste and assess the effectiveness of the strategies for energy savings using A and T Foods and Beverages PLC as a case study. This was with a view to recommending a policy that would enhance the effectiveness of electrical energy savings in the company. A detailed energy audit is adopted for energy project implementation plan and data from the publication of the International Standard Industrial Classification of All Economic Activities (ISIC) in Nigeria for the period of (2011 -2017)were used for the analysis. The sources of energy in the company comprised of electricity from utility company and use of generating sets (fuel). The result showed that the electrical energy consumption in the companies was mainly from generating set. In addition, the total percentage of electric energy consumed from utility company was 40.95% with an average percentage of 5.85%. The total percentage of fuel consumed by the company was 659.05% with an average value of 94.15%. The results identified areas where the company used and wasted energy, and where actions for energy conservation should be implemented. The study therefore established that energy was not sufficiently utilized, and therefore suggested possible strategies for efficient energy usage for the company.

Keywords: Energy Audit, Energy Saving, A and T Food and Beverages PLC, ISIC, Power System, Generating Set, Electric Utility Companies.
