Commercial Generator Selection Guide: Guaranteeing Uninterrupted Business Continuity


Businesses face significant risks during power outages, ranging from financial losses to equipment and data damage. To mitigate these disruptions, having a dependable backup power source is paramount. Commercial generators offer a critical solution, providing backup power to sustain business operations during grid failures. This guide explores the variety of generators available, key considerations for selection, and the potential risks linked to generator power failures.

Understanding Commercial Generators and Their Functionality:

Critical during power outages, commercial generators automatically activate to supply power to businesses. Working in three phases, these generators meet higher electrical demands compared to residential models. Equipped with an automatic voltage regulator, they manage voltage, minimizing surges and power fluctuations. Crucial in sectors like healthcare and retail, they ensure a continuous power supply for life-preserving equipment.

Generators operate through electromagnetic induction, transforming mechanical energy into electrical energy. This process involves the engine generating motion, creating electrical charges, and converting mechanical energy into an electrical current to power various equipment

Varieties of Commercial Generators:

Natural Gas Generators:

Utilize natural gas, convenient for businesses already connected to natural gas lines.

Eliminate concerns about on-site fuel storage.

Diesel Generators:

Efficient and cost-effective, renowned for affordability and robust power capabilities.

Suitable for businesses requiring substantial power during outages.

Propane Generators:

Offer quieter operation but come at a higher cost compared to other fuel options.

Noted for their extended shelf life.

Dual Fuel Generators:

Operate on both diesel and natural gas, ensuring continuous power with backup fuel sources.

Selecting a Generator for Your Business:

Numerous factors influence commercial generator choice:

Power Requirements and Size:

Assess energy needs during outages to choose an adequately sized generator.


Decide between portable or stationary generators based on business requisites.

Fuel Selection:

Choose fuel types based on availability, cost, and power demands.

Noise Emissions:

Consider noise regulations and customer disturbances, opting for quieter models if necessary.

Cost Consideration:

Balance generator investment against potential revenue loss during outages.


Evaluate the required duration of generator operation to cover emergency outages adequately.

Risks Associated with Generator Power Failures:

Generator malfunctions pose risks to businesses:


Accumulation of soot and unburned fuel during long idle periods hampers performance.

Regular load bank testing prevents wet-stacking.

Empty or Poor-Quality Fuel:

Empty tanks or low-quality fuel can lead to generator failures.

Regular fuel quality checks are crucial for reliability.

Coolant or Fuel Leaks:

Extended inactivity may cause coolant or fuel leaks.

Regular inspections prevent dangerously low levels that render the generator inoperable.

Neglected Maintenance:

Irregular maintenance is a common cause of generator failure.

Scheduled maintenance ensures generator health and identifies potential issues.


Selecting the appropriate commercial generator involves assessing power needs, fuel options, and potential risks. It is an investment that ensures uninterrupted business operations during power outages, safeguarding against financial losses and operational disruptions. Consistent maintenance and adherence to safety protocols are imperative for the reliable performance of commercial generators.
