Generator Sizing
How to Choose the Right Generator for Your Facility
Selecting the right generator is critical to ensuring reliable backup power. An undersized generator may struggle to support critical equipment during startup, while an oversized generator can increase equipment, installation, and operating costs.
Generator Systems helps businesses, municipalities, healthcare facilities, manufacturers, and industrial operations determine the right generator size based on their facility’s electrical requirements, operating conditions, and future needs.
Why Generator Sizing Matters
Proper generator sizing helps ensure:
- Reliable backup power during outages
- Successful startup of motors and critical equipment
- Stable voltage and frequency performance
- Improved fuel efficiency
- Lower equipment and installation costs
- Capacity for future expansion
Because every facility has unique power demands, accurate generator sizing is essential for long-term system reliability and performance.
Factors We Consider
Our team evaluates a range of electrical, operational, and site-specific requirements when determining the appropriate generator size.
Running Load Requirements: We calculate the total electrical demand required to operate your facility during an outage, including critical and essential loads.
Motor Starting Loads: Large motors can require significantly more power during startup than during normal operation. We evaluate starting requirements for equipment such as:
- HVAC equipment
- Pumps
- Compressors
- Process equipment
- Industrial motors
Load Sequencing: Not all equipment needs to start simultaneously. By analyzing startup sequences, priority loads, and operating conditions, we can often optimize generator capacity and reduce overall project costs.
Power Quality Requirements: Facilities with sensitive electrical equipment may require additional analysis to maintain proper power quality and reliable performance. This can include:
- UPS systems
- Variable Frequency Drives (VFDs)
- Automated manufacturing equipment
- Communication systems
Fuel Type & Site Conditions: Generator sizing may also be affected by:
- Natural gas availability
- Diesel fuel requirements
- Installation location
- Ambient temperature
- Elevation
- Future growth plans
