How Much Do Commercial Generators Cost? And Does Your Business Need One?
When the power goes out, your business can’t afford to wait. Whether you run a retail shop, healthcare facility, data centre, or manufacturing plant, an unexpected outage can bring operations to a grinding halt. That’s why more and more businesses across the Maritimes are choosing to invest in commercial generators—to keep the lights on and critical systems running when the unexpected strikes.
But just like any major investment, commercial generators come with both benefits and considerations. If you're thinking about adding one to your business, this guide will help you weigh the pros and cons so you can make the right decision for your team and your operations.
The Benefits of Commercial Generators
Uninterrupted Power, When It Matters Most
A commercial generator automatically kicks in when your primary power source fails. That means your operations can continue without skipping a beat—no scrambling to find flashlights or shutting down systems. This reliability can prevent data loss, protect sensitive equipment, and help you avoid the financial risks of unexpected downtime.
Keep Your Business Running, No Matter What
If your business depends on continuous power, a generator isn’t just helpful—it’s essential. Whether you're safeguarding medical equipment, protecting digital infrastructure, or maintaining production schedules, a generator helps ensure you can keep serving your customers and maintain business as usual—even during extended outages.
Tailored to Your Needs
Commercial generators are available in a wide range of sizes and capacities, making it easier to find a model that’s the right fit for your business. As your needs grow, many systems can scale right along with you, offering long-term flexibility without the need for a complete overhaul.
Safety and Security, Even in the Dark
Power outages can compromise everything from your security system to your emergency lighting. A generator ensures that these systems stay online, helping to keep your team safe and your property secure—no matter how long the power is out.
Protection from Surges and Spikes
When the power flickers or suddenly comes back online, it can wreak havoc on your electronics. Commercial generators often include voltage regulation and surge protection features to shield your equipment from electrical damage, helping you avoid costly repairs or replacements.
Things to Consider Before Investing
Environmental Impact
Most commercial generators run on diesel or natural gas, both of which produce emissions. If your business is working toward sustainability goals, this is something to keep in mind. That said, there are increasingly cleaner options on the market, and we can help you explore solutions that reduce your environmental footprint.
Noise and Placement
Generators can be loud—and depending on your location, that noise might not be welcome. You'll also need to plan for where the unit will be installed, ensuring it doesn't detract from the appearance or functionality of your property. Many newer models offer sound-reduction features and sleek enclosures to help address these concerns.
Ongoing Fuel and Maintenance Needs
Generators depend on fuel to run, and having a solid fuel supply strategy is essential—especially during emergencies. Maintenance is also a key factor in ensuring your system is ready when you need it. This includes everything from regular testing to fuel storage upkeep. We can work with you to create a maintenance plan that keeps your generator in top shape year-round.
How Can I Choose The Right Generator Size?
Selecting the right generator size is crucial to ensure it meets your business's power demands without overextending your budget. Here's a general guideline:
Small to Medium-Sized Businesses:
Retail Applications: A common formula is 50 kW plus 10 watts per square foot.
Example: For a 3,000 sq. ft. retail space:
Base: 50 kW
Additional: 3,000 sq. ft. x 10 watts/sq. ft. = 30 kW
Total: 80 kW
General Commercial Applications: The guideline is 50 kW plus 5 watts per square foot.
Example: For a 5,000 sq. ft. office:
Base: 50 kW
Additional: 5,000 sq. ft. x 5 watts/sq. ft. = 25 kW
Total: 75 kW
Larger Businesses:
For expansive facilities with substantial equipment, a detailed assessment is essential. This involves calculating the total running and starting watts of all equipment and adding a reserve margin (commonly 25%) to accommodate future expansions and ensure reliability.
