7 Powerful Tips for Buying a Generator

Power outages are more than an inconvenience, they can bring business operations to a halt, impact customer satisfaction, and result in significant financial losses. But before buying a generator, there are several important factors to evaluate to ensure the unit that you choose meets your business’s needs both now and in the future. Whether you’re running a hospital, data center, manufacturing facility, or office complex, a commercial generator is a critical investment in continuity and resilience.

Determine Your Power Requirements
Before buying a generator, start by assessing your facility’s electrical load. This includes identifying which systems and equipment need to stay powered during an outage, such as lighting, HVAC, refrigeration, security systems, data servers, elevators, etc. A professional load analysis will help calculate the total kilowatts (kW) required for seamless operation during a power loss. It’s essential to plan not just for today’s needs but also for potential future growth, as this generator could provide your business with a backup power source for over 20 years.
Choose the Right Fuel Type
Commercial generators typically run on diesel, natural gas, or propane. Each has its pros and cons:
- Diesel: Known for reliability and long engine life. Requires regular fuel maintenance (fuel polishing and testing).
- Natural Gas: Convenient and clean-burning, but depends on utility supply which may not be available in all locations.
- Propane: Long shelf life and cleaner than diesel, but requires onsite storage and may be more expensive in the long term.

Location, Permits, and Installation Requirements
Where you place your generator affects everything from performance to compliance. Consider:
- Indoor vs. Outdoor Installation
- Noise Ordinances
- Exhaust Routing
- Ventilation and Clearance
- Local Building Codes and Environmental Regulations
Tip: If you are buying a generator to replace an existing generator, changes to the building and electrical codes might not allow the replacement to be installed in the same location.

Understand Transfer Switch Options
An automatic transfer switch (ATS) seamlessly shifts your power source from the grid to the generator during an outage. Choosing the right type of ATS is critical for ensuring safety, compliance, and uninterrupted operations. If your business can’t afford even a split-second power loss, the transfer switch becomes a crucial part of your system design.
Budget and Options
Buying a generator systems represent a significant capital investment, so it’s critical to make a well-informed decision. With the wide array of commercial generator options on the market today, it can be overwhelming to determine which system is the best fit for your business. Some models offer enhanced fuel efficiency, others prioritize ultra-low emissions, and many feature extended warranties or increased reliability for mission-critical operations. Pricing can vary considerably depending on the brand, size, and included technology, so it’s essential to look beyond the sticker price and consider the total cost of ownership over the generator’s lifespan.
