In An Era Where The Electricity Generation Industry Focuses On 24-Hour Operations To Maximize The Production Of Electrical Energy, Which Is Needed For Development And As A Driving Force For Office Equipment And The Economy Of The People In Timor- Leste, It Is Pushed To Its Absolute Limit To Meet This Demand. With The Increase In The Operation Of The Electric Energy Generation Unit, The Wear And Tear Of The Engine Components Will Increase. So, The Need For Increased Engine Parts, To Prevent Failure. To Remedy This Situation And Guarantee The Machine’s Continued Peak Performance, Preventative Maintenance Is Executed. Preventive Maintenance (PM) Is One Subfield Of Maintenance That Aims To Forestall Failures Before They Manifest. The Maintenance, Production, And Management Teams Will Need To Work Closely Together To Make PM A Success. This Article Is A Case Study Of Electrical Diesel Timor-Leste (EDTL), A Firm With Two Power Production Facilities Located In Hera And Betano, And It Examines The Causes Of Inefficient PM Activity And The Ramifications This Has For The Organization.
