Preventive Maintenance (PM)

A well-planned preventive maintenance (PM) program, with regularly scheduled maintenance is essential to ensure reliability of all power generation equipment. This approach also minimizes downtime, as operators can arrange to have backup power while the primary unit is being serviced.

WPP’s Preventive maintenance inspections include an 80-point inspection checklist:  

  • Engine lubricating system (6) 
  • Engine cooling system (14) 
  • Engine air intake system (4) 
  • Engine exhaust system (3) 
  • Engine fuel system (12) 
  • Engine electrical system (10) 
  • Other engine related systems (4) 
  • Generator and distribution system (8) 
  • Generator running inspection (12)  
  • Departure inspection (7) 

Benefits of a preventive maintenance program for your generator or engine:

  • Regulatory compliance (NFPA, TCEQ)
  • Avoid downtime and costly repairs
  • Eliminate damage caused by deferred maintenance
  • Minimize loss of revenue due to unplanned downtime

Regularly scheduled maintenance does more than protect your investment and operating continuity. Unavoidable failures that may occur during operation usually become evident during a load test or inspection when the generator is not being used.


Load Bank Testing

Load bank testing is an essential requirement to maintaining a generator set.  Load bank services ensure generator performance reliability under any load condition.  WPP offers load bank testing as a standalone service to customers wishing to have their own power generation equipment tested on demand, either in the field or at our location.  The National Fire Protection Association (NFPA 110) has established the standards for monthly maintenance and operation for standby generators that states, ” Generators should be exercised monthly at 30% of the nameplate rating or loaded to the minimum engine exhaust temperature recommended by the engine manufacturer.”

Additional benefits of load bank testing include:

  • Reduce wet stacking problems
  • Exercising of standby generator sets
  • Ensures proper installation and load transfer
  • Load optimization

Fuel Polishing, Management & Analysis

recommends that “diesel fuel be tested for degradation no less than twice annually with a maximum of 6 months between testing at least once per year.”    WPP offers FREE diesel fuel sampling in order to determine if your fuel is contaminated.  During scheduled maintenance visits, WPP can also refuel or top off your diesel tanks with high-quality fuel.  We also offer optional fuel analysis, sampling and treatment for contamination as an optional service with each visit.
