Triennial generator service, also known as a “level 3 service” or “3-year service,” is a routine maintenance service performed every three years for commercial standby generator systems. Triennial service covers maintenance and replacement of engine components that are not typically replaced during Annual, Semi-Annual, or Quarterly maintenance visits. This includes maintenance items such as belts, hoses, coolant, and air filters.
Including Triennial service to a routine generator maintenance plan provides added protection for your backup power system, and a reduced risk of unexpected service costs and downtime.
Here are some of the benefits for generator owners to proactively include Triennial service in their maintenance plan, rather than allowing these maintenance items to naturally deteriorate or possibly fail during generator operation.
Scheduling this routine maintenance every three years can reduce the risk of unplanned, emergency service calls, which are typically more expensive than a routine maintenance visit. For example, if a coolant hose breaks and the generator fails to start during a power outage, these situations often require after-hours repairs with overtime labor costs for the Generator Technician to perform the repair after regular business hours. If the replacement parts are not readily available, this could add expensive overnight shipping costs for the required parts. Also, if you can’t wait for the parts to arrive, you may need a temporary rental generator which could add more expense to the situation.
Prevent Equipment Failures and Downtime
As mentioned above, a generator failure during a power outage can result in unexpected and costly service fees for your business. This could also come with the risk of lost revenue, and for Critical and Life-Safety facilities, the cost could extend much further than a financial issue. When an emergency generator cannot operate, the facility is at risk of having zero backup power, potentially resulting in downtime, safety concerns, critical loss, and liability.
When an unexpected failure occurs such as a broken fan belt, the generator could be out of commission until a Generator Technician can arrive onsite to assess the failure, locate the required part, and make the necessary repair. There is always a risk that the Technician may not have the exact part needed in his service truck, which would require additional site visits and possible delays to order the part. By replacing these generator maintenance items routinely every three years, the risk of failure is greatly reduced.
Control Your Budget
Scheduling this service on a routine basis allows your facility and CFO to budget for these items ahead of time. This prevents the need to get approval to replace maintenance items at an unexpected time, such as the point of an equipment failure. You also have more control over the service bill since the cost for routine maintenance is typically predetermined, rather than incurring the expense of an emergency service call.
