Abstract
Through its industry advancement strategy, electric supply stability ranging from electric generation, transmission to its distribution is a paramount. For this, electric power plant with higher reliability and affordable maintenance cost plays an important role. This research was focused on measuring reliability and maintenance cost saving after implementing a conformal asset management (CAM). CAM with 6 keys subjects and 40 sub-subjects was applied and scored using a maturity level adopted from Bradshaw and Abrahamson. Reliability which is indicated by Equivalent Availability Factor (EAF) and Equivalent Forced Outage Rate (EFOR) was determined, while maintenance cost saving was obtained according to data taken before and after implementing CAM. Data was taken in the year period of 2012 to 2019 which was divided in the period of 2012 to 2014 as data before implementing CAM and 2014 to 2019 as data after implementing CAM. The research found that by implementing CAM to the affiliated electric power plant, the AM maturity level was in range of 2 to 5 from scale 5 or the average level was 3.5. In this, some of sub-subject within subject of Strategy and Planning, Life-Cycle delivery, Asset Information, and Organization and people were critical area identified for improvement. For its reliability and maintenance cost saving, the company has had better reliability and maintenance cost saving after implementing CAM. EAF improved by 10% and EFOR dropped to 2%, while maintenance cost saving increased by 30%.
