EXERGY AND ENERGY ANALYSIS OF NIGER DELTA UNIVERSITY POWER PLANTS
Power generation and distribution in Nigeria is not regular and most industries and institutions are apparently sustained by electricity generated from diesel driven generators, leading to high cost of products and services, including the contribution to undesirable emissions. This is not helping the increase in the rate of exploitation of energy resources resulting in the continuous depletion of energy reserve. The key object is to adopt energy management in every field of human endeavor to reduce wastages of energy sources and enhance cost effectiveness without affecting productivity and quality. This research work was designed to study and audit energy consumption in Niger Delta University, Wilberforce Island, Bayelsa state Nigeria by creating a balance between energy consumption and supply, with a view to minimizing wastages and reduces cost on energy. The audit was carried out using a three phases, ten steps energy audit model. Results show that using generators cost average of 25 to 30 Naira (Nigerian currency) kWh of electricity, while supplies from Power Holding Company of Nigeria (PHCN) cost an average of 4 Naira per kWh of electricity. Thermal and exergetic efficiencies obtained from the analysis are in ranges of 13.59% to 15.96% and 0.636% to 2.686% respectively. The study will give the Niger Delta University a guide to maximize the energy production and consumption in the institution.
