Commercial Generator FAQs: What Houston Businesses Need to Know
What size generator does my business need?
Generator size depends on what you need to power during an outage:
- Small retail: 20-50kW for lights, registers, and basic systems
- Restaurants: 80-150kW for refrigeration, cooking equipment, and HVAC
- Medical offices: 30-100kW depending on equipment
- Industrial facilities: 100-500kW or more
We perform a detailed load calculation to determine your exact requirements.
What's the difference between standby and portable generators?
Standby generators are permanent installations that start automatically during outages. They connect directly to your electrical system and can run for extended periods.
Portable generators require manual setup and connection during an outage.
For most businesses, automatic standby generators are the only practical solution for maintaining operations during extended outages.
How much does commercial generator installation cost in Houston?
Commercial generator electrical installation typically costs:
- Small-medium businesses: $5,000-$15,000 for installation, plus generator cost ($10,000-$30,000)
- Larger industrial systems: $20,000-$50,000 for installation plus equipment
While significant, this investment often pays for itself in a single day of prevented downtime.
How long does generator installation take?
Electrical installation: 2-5 days (transfer switch, panel connections, wiring, testing)
Complete project: 2-4 weeks (including concrete pad, mechanical connections, permitting)
We coordinate with your generator supplier and mechanical contractors to ensure efficient installation.
Can a generator power my entire business?
Yes, with proper sizing. However, many businesses choose to power only critical systems to reduce generator size and cost, including:
- Essential equipment
- Safety systems
- Core operations
We’ll help determine the most cost-effective approach for your business.
What type of fuel is best for commercial generators?
Each fuel type has advantages:
- Natural gas: Clean-burning with unlimited runtime, requires adequate gas line
- Diesel: Extremely reliable and fuel-efficient, requires storage and maintenance
- Propane: Good reliability with on-site storage
We’ll evaluate options based on your location, runtime needs, and existing infrastructure.
Do commercial generators require special permits in Houston?
Yes. Commercial generator installations typically require:
- Electrical permits
- Mechanical permits
- Sometimes fire marshal approval
As licensed electrical contractors, we handle all electrical permitting requirements and can coordinate with other contractors for complete compliance.
How quickly will the generator start during a power outage?
Critical facilities sometimes add uninterruptible power supplies (UPS) to bridge this brief gap for sensitive equipment.
How long can a commercial generator run continuously?
Run times depend on fuel type:
- Natural gas: Indefinitely (as long as gas service remains active)
- Diesel/propane: 24-72 hours without refueling (depending on tank size)
Extended runtime packages are available for critical facilities requiring uninterrupted operation.
What maintenance does a commercial generator need?
Regular maintenance includes:
- Electrical components: Quarterly inspection of transfer switches, controls, batteries, and connections
- Generator: Engine maintenance like oil changes, filter replacements, and fuel system service
We can coordinate with your generator maintenance company to ensure complete system care.
