If you're considering a standby generator for your home, you're probably wondering: how much does it really cost? Between installation, equipment, permits, and fuel connections, the final price can vary widely. In this guide, we'll break down the key costs, what influences them, and how to make the smartest investment in backup power.

What Is a Standby Generator?

A standby generator is a permanent backup power system that automatically turns on when your home loses electricity. Unlike portable generators, standby generators are connected directly to your home’s electrical panel and a fuel source like natural gas or propane. They're ideal for homeowners who want uninterrupted power during outages.

The Average Cost of a Standby Generator in Canada

In 2025, the average homeowner can expect to pay between $7,000 and $15,000 for a fully installed standby generator. Here's a basic breakdown:

• Generator unit: $2,500 to $7,500
  
• Installation (electrical + fuel connection): $3,000 to $5,000
  
• Transfer switch: $500 to $2,000
  
• Permits & inspections: $200 to $500
  

The final cost depends on your home size, power requirements, and the complexity of the installation.

Factors That Affect the Cost of a Standby Generator

Several variables can impact your final bill:

‍

1. Power Output (kW Rating)

A small standby generator (7.5 kW) might only cost $6,000 installed, while a whole-home solution (20 to 24 kW) could push $14,000 or more.

‍

2. Fuel Type and Availability

Hooking up to an existing natural gas line is often cheaper than installing a large propane tank. However, propane may be your only option in rural areas.

‍

3. Installation Location

The farther your generator sits from your electrical panel and fuel source, the more you'll pay in labor and trenching costs.

‍

4. Permits & Local Regulations

Cities like Vancouver may have strict permitting rules for standby generators. Always check if you need electrical, gas, and noise permits.

‍

5. Optional Add-Ons

Want remote monitoring? A weatherproof enclosure? A quiet-running model? These extras will add to your total cost.

Ongoing Costs to Consider

A standby generator isn’t just a one-time expense. Budget for:

• Annual maintenance: $300 - $600
  
• Fuel (if using propane): Costs vary depending on use
  
• Repairs: Unexpected service calls can cost hundreds

How to Get an Accurate Quote

The only way to get a true cost estimate is through an on-site consultation. A licensed installer will:

• Calculate your total electrical load
  
• Recommend the right size standby generator
  
• Assess your gas or propane connection
  
• Estimate trenching, wiring, and switchgear
  
  

Pro Tip: Ask if the consultation fee can be applied toward installation.

Is a Standby Generator Worth the Investment?

If you experience frequent outages, have medical devices that rely on power, or simply want peace of mind, the answer is likely yes. A standby generator can add resale value, protect perishables, and keep your home livable during emergencies.

Final Thoughts on Standby Generator Pricing

Standby generators are a major investment, but for many homeowners, they pay off in security and convenience. Costs range from $7,000 to $15,000, but careful planning, rebates, and off-season deals can help reduce the price. Always work with a licensed, experienced installer.
