Reliability and Availability Improvement Techniques for Nigeria Electric Power Stations

The maintenance of plant in the electric power stations involves an annual expenditure of millions of dollars and it is therefore essential to establish the cost-effectiveness of the present maintenance policies. The major problems in this evaluation are the lack of information and lack of suitable techniques to analyze the information. Most items of electric power plants are complex mechanical units and as such it is extremely difficult to predict their failure although condition monitoring can sometimes be used. This study explores how to use reliability engineering to identify best practice for maintenance work in electric power stations. It identified how to identify failure before their occurrences and how the maintenance management functions can become more conscious of the sole of maintenance management in enhancing has become the prominent management issues for electric utilities.
