Load Bank Testing vs. On-Demand Generator Use: What’s the Difference?
Generators are a lifeline for businesses, farms, and industries that rely on backup power. However, simply running a generator when needed is not enough to ensure long-term reliability. Load bank testing is a crucial process that helps detect performance issues before they cause failures. Many owners of custom-built generators in Saskatchewan rely on this method to keep their equipment in top shape.
Understanding the difference between load bank testing and on-demand generator use can help you make the right choices for your power system.
What Happens During On-Demand Generator Use?
On-demand generator use means running a generator only when power is needed. This could be during a power outage or when extra electricity is required. The generator supplies power to connected equipment but does not necessarily run at its full-rated capacity.
Issues with On-Demand Generator Use:
● May only operate under light loads, leading to poor engine performance
● Does not test the generator’s ability to handle maximum power demand
● Can result in undetected fuel system, cooling, or electrical issues
● Increased risk of failure during critical situations
Relying only on on-demand use may cause unexpected breakdowns, especially if the generator is not properly maintained.
How Load Bank Testing Ensures Reliability?
Load bank testing is a controlled process that checks how well a generator performs under different load levels. A load bank (a device that mimics electrical demand) is connected to the generator, allowing technicians to monitor power output, temperature, fuel efficiency, and overall performance.
Benefits of Load Bank Testing:
● Ensures the generator can handle full-rated capacity
● Burns off excess carbon buildup in diesel engines, improving efficiency
● Identifies potential failures before they become major problems
● Helps meet maintenance and regulatory requirements
Many businesses that invest in used generators for sale in Saskatchewan schedule regular load bank tests to confirm the equipment is in good working condition.
Why Load Bank Testing Is Essential?
A generator that only runs under light loads for long periods can develop wet stacking, a condition where unburned fuel and carbon deposits build up in the engine. This reduces efficiency and increases emissions. Load bank testing allows the generator to operate at optimal temperature, preventing these issues.
Testing also reveals hidden electrical or mechanical problems that could cause failure during an actual outage. Regular maintenance combined with load bank testing ensures that your generator will work when needed.

Questions You May Have
Q1. How often should load bank testing be performed?
A1. Industry standards recommend testing at least once a year for standby generators to ensure reliability and compliance with CSA 282-05 regulations.
Q2. Is load bank testing required for all generators?
A2. While not always legally required, it is highly recommended for standby and backup generators in commercial, industrial, and agricultural settings to ensure performance reliability.
Q3. Can I use my generator normally after a load bank test?
A3. Yes, once the test is complete, your generator will be fully operational and in better condition for handling real-world power demands.
Q4. Does DSG Power Systems offer on-site load bank testing?
A4. Yes, DSG Power Systems provides on-site load bank testing and servicing across Saskatchewan to ensure your generator is ready for emergencies.
Q5. Can load bank testing extend the lifespan of my generator?
A5. Yes, by ensuring proper combustion, preventing wet stacking, and detecting early issues, load bank testing helps keep your generator in top working condition for years.
