Power outages can cause serious disruptions, including financial loss, production delays, and safety risks. Commercial generators are designed to deliver high-capacity backup power for businesses during outages. Unlike portable or home-use models, they are built to handle larger loads and longer run times.
Companies rely on these generators to minimize downtime, protect their equipment, and ensure the safety of employees and customers. From retail stores and hospitals to data centers and factories, commercial generators power essential systems when the main grid fails.
BISON, a global power solutions leader, offers a wide range of commercial generators built for performance, durability, and efficiency. In this article, we’ll cover the types of commercial generators, where they’re commonly used, how to choose the right one, and the key benefits they offer—helping you see why a commercial generator is vital to keeping your business running strong.
Key components and working principle of commercial generators
- Engine: The engine is the heart of the generator. It burns fuel—typically diesel or natural gas—to create mechanical energy, which drives the alternator. Commercial engines are larger and built for durability, enabling them to meet heavy, continuous power demands without interruption.
- Alternator: The alternator converts the engine’s mechanical energy into electrical energy. In commercial units, alternators are built to deliver consistent power output and withstand long hours of use.
- Fuel system: This system stores and supplies fuel to the engine. It includes the fuel tank, pump, filter, and injectors. Larger fuel systems in commercial models support extended operation without refueling.
- Cooling system: The cooling system prevents the engine from overheating. It uses components like a radiator and coolant to manage temperature, especially during long periods of operation.
- Control panel: The control panel lets users monitor and manage the generator. It includes gauges for things like fuel levels, engine temperature, and power output.
- Battery: The battery starts the engine and powers electronics like the control panel. A reliable battery ensures the generator starts quickly when needed.
Different types of commercial generators
By fuel type
- Diesel generators: Diesel generators are known for reliability, high power output, and efficiency. They perform well in tough conditions and are ideal for continuous use in places like construction sites, hospitals, and factories, where uninterrupted power is essential.
- Bi-fuel generators: Bi-fuel generators run on a mix of diesel and natural gas (or propane), providing flexibility and extended runtime. They are excellent for large-scale operations like factories, data centers, and businesses needing high-capacity, adaptable power solutions.
- Natural gas generators: These generators are cleaner-burning and more environmentally friendly. They offer steady, cost-effective power and are best suited for restaurants, office buildings, and retail stores, especially in areas with a stable gas supply network.
- Gasoline generators: These generators are portable, affordable, and widely available. These generators are perfect for short-term use during power outages, outdoor events, camping trips, and small construction projects where mobility and quick setup are priorities.
By power output
- Standby generators: These generators are permanently installed and start automatically during a power outage. Ideal for restaurants, offices, retail stores, and medical centers, they ensure minimal disruption and reliable emergency backup power.
- Prime power generators: Designed for continuous use where grid power is unavailable or unreliable, these generators are ideal for remote sites, construction projects, mining, and temporary facilities. They can run for long hours at variable loads.
- Continuous power generators: Designed for 24/7 operation, these generators deliver stable power to businesses with consistent energy demands. Perfect for data centers, telecom facilities, and manufacturing plants, they ensure uninterrupted operations.
- Portable generators: Compact and easy to move, portable generators are great for temporary power needs, such as outdoor events, mobile businesses, and job sites. Though smaller in size, they offer flexible solutions for short-term or off-grid applications.
Where and how commercial generators are used
- Healthcare facilities: Hospitals, clinics, and medical centers require consistent power to operate life-saving equipment, such as ventilators, incubators, and monitoring devices.
- Data centers: Data centers rely on constant power to protect servers, communication systems, HVAC, lighting, and sensitive data. Generators prevent costly downtime, data loss, and security risks.
- Retail stores: Supermarkets, malls, and retail shops need power for lighting, checkout systems, refrigeration, and security. Generators keep operations running and prevent product loss during outages.
- Manufacturing and industrial sites: Production facilities use heavy machinery and automated systems that must operate without interruption. Commercial generators provide the reliability needed to keep production lines running and reduce the risk of costly downtime.
- Construction site: Often located in areas without grid access, construction sites use generators to power tools, lighting, and equipment, ensuring progress continues regardless of location.
- Office buildings: Office operations depend on electricity for computers, HVAC, lighting, and communication systems. Generators support business continuity during blackouts.
- Hospitality industry: Hotels, resorts, and event venues need power to serve guests comfortably. Generators keep services running smoothly, from lighting and climate control to kitchen and entertainment systems.
Why choose a commercial generator?
- High power output capacity: Commercial generators deliver significantly more power than residential models—typically from 50 kW up to 2000 kW or more. This allows them to support entire buildings, multiple systems, and heavy equipment.
- Uninterrupted business operations: Commercial generators are designed to run longer under more demanding conditions, making them more durable and reliable. To ensure business productivity, commercial generators are usually designed to run continuously for hours or even days.
- Protection for sensitive equipment: Power outages and surges can damage expensive machinery, computers, and data systems. A commercial generator provides stable, reliable power to protect essential equipment.
- Safety and security: Commercial generators ensure that safety systems remain up and running, including emergency lighting, security cameras, fire alarms, and HVAC systems, so that people and property are safe.
- Cost savings over time: While the upfront cost of a commercial generator can be high, it pays off by preventing revenue loss during outages. It also helps avoid product spoilage, equipment repairs, and delayed services.
- Regulatory compliance: Commercial generators are typically designed to industry standards and maintain a high standard of uninterrupted service once started. Certain industries can avoid fines and legal issues and meet regulatory requirements by equipping themselves with commercial generators.
Key considerations when selecting a commercial generator
Power demand assessment
List the devices that need to be run by the generator, add up their total power or amperage (taking into account the starting surge of equipment such as motors), and finally add a 20-30% buffer to cope with future power growth to know your power needs.
Fuel types
- Diesel: Excellent reliability, fuel efficiency, and operating time, ideal for heavy-duty operations, but may emit more pollutants and require more maintenance.
- Gasoline: More accessible and typically cheaper upfront, but not ideal for continuous operation due to higher volatility and shorter shelf life.
- Natural gas: Cleaner and quieter, with lower emissions. However, their operating costs may be higher, and a gas supply is required.
Noise levels and emissions regulations
Choose a commercial generator with the following configuration, which will be quieter:
- Soundproof enclosures or mufflers
- Low-vibration engine designs
Also, check local emissions laws—especially for diesel units—to ensure compliance and avoid penalties.
Space requirements and installation
Consider accessibility to the installation site. Reserve enough space for the generator, ventilation system, fuel storage system, exhaust system, fueling access, and soundproofing.
Budget
Calculate the total cost of ownership (TCO), which includes:
- Purchase cost
- Fuel consumption
- Maintenance and service
- Operational lifespan and efficiency
Useful function options
- Automatic transfer switch (ATS): Automatically activates the generator during outages, minimizing downtime.
- Remote monitoring: Allows real-time tracking of generator status, fuel levels, and diagnostics via mobile or web platforms.
