Determining generator size is crucial for companies in need of faithful backup power. However, this task can be complex due to various factors that need thought. Therefore, companies must determine their power needs and explore financial solutions. This guide explains the process of deciding generator size for your business while including in these factors.
Understanding Industrial Generators
To begin, industrial generators convert mechanical energy into electricity, offering backup power during outages or in remote areas. They come in different sizes, capacities, and fuel options (diesel, natural gas, propane, gasoline). These robust machines support critical systems and locations without grid power.

Why Generator Sizing is Important
Selecting the appropriate generator size is vital to ensure continuous business operations during power outages. Therefore, an undersized generator may fail to power necessary systems, resulting in idle time and lost revenue. Conversely, an oversized generator could lead to unnecessary equipment costs.
Calculating Your Power Needs
Determining your generator size starts with calculating your power requirements. This involves identifying essential and non-essential systems needing power during outages and calculating the total power demand.
Step 1: Determine Your Essential Load
The essential load is the minimum power needed to sustain core functions during outages. This includes systems like lighting, computers, security setups, and communication devices.
Step 2: Identifying Non-Essential Load
Adding the essential and non-essential loads gives the total load. This represents the power output required from the generator during outages.
Step 3: Calculate Your Total Load
Once essential and non-essential loads are settled, adding these two yields the total load. This figure represents the power output required from the generator during outages.
Understanding Power Ratings
Industrial generators are rated in kW or kVA. kW measures actual power delivered to the load, while kVA indicates total generated power.
The difference between kW and kVA centers around the power factor, which indicates the ratio of real power (kW) to apparent power (kVA). It gauges the generator’s ability in delivering power to the load.
Power Factor
Additionally, the power factor varies with the load type. Resistive loads, like lighting and heating systems, have a power factor of 1.0, equating kW and kVA. Inductive loads, such as motors and pumps, have a power factor below 1.0, causing kVA to exceed kW.
Factors Affecting Generator Sizing
Determining the right generator size includes considering factors affecting performance. These include altitude, temperature, humidity, load type, and motor starting. More information about fuel usage can be found here.
Altitude
Generators are rated at sea level. If located at higher altitudes, a larger generator compensates for lower air density.
Temperature
Generators function within defined temperature ranges. Extreme temperatures require generators designed for those conditions.
Humidity
Humidity affects electrical equipment, including generators. High-humidity environments require generators made for such conditions.
Load Type
Generator performance is affected by the load type. Inductive loads, like motors and pumps, require higher starting currents, requiring a larger generator.
Motor Starting
Starting motors places heavy demands on generators. Motor start-ups may demand up to six times their rated current for a short time. Businesses using motors require generators capable of handling these surges.

Standby vs. Prime Power
Two generator types exist: standby and prime power. Standby generators supply backup power during outages, while prime power generators provide continuous power in off-grid locations.
Generator Sets
Choose from a range of generator sizes and configurations, considering power output, fuel efficiency, noise level, and emissions.
Single vs. Three-Phase Power
Opt for the fitting power output (single-phase for lighter loads, three-phase for heavier loads) to match business needs.
Installation and Maintenance
Ensure proper installation and maintenance, including secure placement, accurate electrical connections, and regular upkeep for optimal performance. More info on maintenance can be found here.
Conclusion
Undeniably, accurately determining generator size is essential for seamless operations during emergencies. Understand power requirements, sizing-affecting factors, and make informed choices to bolster your business’s preparedness.
FAQs
1. What is the purpose of an industrial generator?
An industrial generator is designed to provide backup power in case of electrical grid failures or as a primary power source in locations without access to a reliable electrical grid. These generators are commonly used in commercial and industrial settings to ensure continuous operations.
2. Why is it essential to correctly size an industrial generator for your business?
Sizing an industrial generator correctly is crucial to ensure it can meet your business’s power needs during an outage. An undersized generator may not provide enough power, leading to downtime and potential damage to equipment. Conversely, an oversized generator can be costly to operate.
3. How do I determine the power requirements for my business?
You should perform a comprehensive load analysis to determine your business’s power needs. This analysis should include all electrical appliances, machinery, and equipment that would need power during an outage. Consider both the starting (surge) and running (continuous) power requirements of each device.
4. What factors should I consider when sizing an industrial generator?
When sizing an industrial generator, consider factors such as the total load, the type of equipment you have, the starting requirements (motor loads), the length of time of backup power needed, and any future growth plans. It’s also important to account for environmental conditions and altitude, as these can affect a generator’s performance.
5. How can I calculate the total load for my business?
You can calculate the total load by adding up the power (in watts or kilowatts) required by each electrical device or piece of machinery that needs to operate during a power outage. Be sure to account for both the initial surge and continuous power use.
6. What is the difference between standby and prime generators?
Standby generators serve as backup power sources and usually come into play during a grid failure. On the other hand, manufacturers design prime generators for regular operation, allowing them to function as the primary power source. When deciding the appropriate industrial generator size for the needs of your company, you must identify the required type.
