What Size Generator Do You Need for Your Business? A Quick Guide for Toronto Owners

Generators keep businesses running during power outages, large events, and construction projects. But choosing the right size can be tricky—too small, and you’ll overload it; too big, and you’ll waste fuel and money.
Here’s how Toronto businesses can figure out the right generator for their needs.

1. Know Your Power Needs

Make a list of the equipment you need to run during an outage or event:

  • Essential lighting
  • Refrigeration or cooling systems
  • Computers or servers
  • Machinery or tools

Add up the wattage (check the labels on your equipment). It’s better to include a 20–25% buffer for start-up surges.

2. Match the Generator to Your Usage

  • Small Commercial Spaces (retail, offices): 10–20 kW is usually enough to power lights, computers, and basic appliances.
  • Restaurants or Food Trucks: 20–50 kW to handle refrigeration, cooking equipment, and lighting.
  • Construction Sites or Large Events: 50–100 kW or more, depending on heavy machinery and continuous use.

3. Don’t Forget Fuel Efficiency

Bigger isn’t always better. Oversized generators burn more fuel than necessary, increasing operational costs. Proper sizing saves fuel and keeps maintenance simpler.

4. Plan for Reliable Fuel Delivery

No matter the size, a generator is only as good as its fuel supply.
