This study examines the dependability and operational performance of electric power generating units TG1 and TG2 at the Kwale Gas Recycling Plant, Nigeria. In the context of increasing industrial demand for higher production efficiency with minimal capital expenditure, enhancing equipment reliability, availability, and maintainability has become essential for sustainable operations. The research evaluates the relationship between equipment failure rates, maintenance strategies, and the economic implications of power generation losses due to system unavailability. Using reliability engineering principles, key performance indicators such as Mean Time Between Failures (MTBF), Mean Time To Repair (MTTR), and operational availability were analyzed to assess system effectiveness. The study also highlights the role of modern maintenance approaches, including Reliability-Centered Maintenance (RCM), Total Productive Maintenance (TPM), and Computerized Maintenance Management Systems (CMMS), in improving plant performance and reducing downtime. Findings indicate that over time, the cost associated with lost power generation due to equipment failure significantly exceeds the initial capital investment of the generating units. This underscores the importance of adopting proactive and data-driven maintenance strategies to enhance dependability and optimize lifecycle costs. The study concludes that integrating advanced reliability models and continuous maintenance improvement frameworks can significantly improve operational efficiency, safety, and long-term economic performance of gas turbine power plants.
