Evaluación de metodologías de mantenimiento existentes aplicadas a centrales termoeléctricas, caso de estudio ecuatoriano

Abstract

CONDITIONING OF PROJECT PUBLICATION. study examines the impact of maintenance strategies on the performance indicators of an Ecuadorian thermoelectric plant with the aim of finding tangible operational efficiencies. The primary motivation was to determine how maintenance, rather than being a mere technical obligation, could be designed to improve plant reliability, especially when the country requires additional energy support during dry seasons or hydroelectric system emergencies. A longitudinal comparison of operations over two consecutive years demonstrated an improvement in availability, utilization, and overall OEE (Overall Equipment Effectiveness) performance. The results observed in 2023 indicated significant challenges with equipment availability, which prevented full utilization of capitalized capacity. In contrast, 2025 showed a notable improvement, with all indicators showing considerable growth, reaching international efficiency standards. These results were achieved through the implementation of improved maintenance programs, combined with a more proactive approach, supported by more robust engineering decisions adopted by the specific strategy employed. It became clear that even with moderate investment strategies, a power plant can achieve significant competitive returns. Likewise, with efficient management and sound decisions, exceptional results are possible.
