What Are The Benefits Of Industrial Generator Load Banking?

By: Patti Dinneen


Proper testing of a facility's backup power generation system is one of the only ways to identify generator system weaknesses in the case of unplanned power disruptions. Due to insufficient testing, a number of facility managers still remain unaware of the weaknesses of their backup solutions. Without regular testing, diesel engines that are regularly run on very low loads – or no load at all – become increasingly unreliable and costly to maintain. The effects include smoky exhausts, carbon build-up, fuel system problems and lubricating oil deterioration, all of which decrease reliability and add to running costs. In this post, we will discuss what a load bank test is, and how it can benefit the security of your generator, while giving you assurance that your generator will work when necessary.

What Is A Load Bank Test

A load bank test provides an artificial load that brings the engine to an acceptable operating temperature, ensuring functionality when your business needs it most.  Load banking checks the generator engine’s ability to perform and provides the required horsepower needed in an emergency. Generators typically run at a level less than the unit’s rated output capability which is why testing is so important. By providing an artificial load to the generator, the engine is brought to a full load operating temperature, ensuring functionality in a power failure.

A load-bank test is an essential part of any preventive maintenance practice to ensure your standby generator performs in the event of a power failure.

How Does It Work?

A trained service technician will come right to your facility with a machine called a load bank. We hook it up to your generator and flip a switch. The generator will have load applied to full rating.

We start the generator off slow, by having it work as if it needs to provide power at just 25% of its capacity. As each hour passes, we increase the load by 25%. At the end of four hours, your generator will have run at 100% capacity and any problems will be apparent.

The Benefits Of Load Banking Tests:

  • Assure facility managers that their generators will be able to work to 100% capacity.
  • Reduces the potential risk of generator failure during an emergency.
  • Reduces the chances of mechanical failure due to extreme stress on engine system paramaters.
  • Helps to prevent wet stacking, which reduces engine lifecycle and efficiency.
  • Cleans the generator by removing all the carbons from of the engine.

Businesses that have critical power needs such as hospitals, financial institutions, computer data centers, and manufacturing plants, in particular, would benefit greatly from load bank testing.

At minimum, a load bank test should be performed on an annual basis to improve the life of the engine and alternator.
