Backup Generator Installation
The March 2025 ice storm left 63,000 Hydro One customers without power across Peterborough and Northumberland County, some for over a week. Rural properties took even longer to restore, with well pumps failing, septic systems backing up, and sump pumps leaving basements vulnerable to flooding. Professional backup generator installation ensures your family stays comfortable and safe when the grid fails.
Why Backup Power Matters in Our Region
If you've lived in Northumberland County, Durham Region, or the Peterborough area for any length of time, you know power outages aren't a question of "if" but "when." The March 2025 ice storm was described as the worst since 1998, with over 20mm of ice accumulation destroying power lines and causing over $11 million in city cleanup costs for Peterborough alone. The storm brought down tree limbs weighted with ice, breaking over 1,900 poles region-wide. Some rural properties remained without power for 7 to 10 days, while water-access-only properties took weeks to restore.
Ice storms represent the most devastating threat to our electrical infrastructure, but they're not the only concern. The May 2022 derecho windstorm caused widespread destruction across Ontario. Summer thunderstorms bring lightning strikes that damage distribution equipment. Heavy snow loads stress infrastructure and make repairs difficult when roads become impassable. Aging grid equipment fails periodically, and vehicle accidents striking utility poles create localized outages that can last hours or days depending on location and repair complexity.
What Fails When Power Goes Out?
Without power, rural properties face cascading failures that make backup generators a necessity rather than luxury. Well pumps stop working, leaving homes with no water supply for drinking, cooking, or toilet flushing. Septic pumps fail, causing system backups that can overflow into basements. Sump pumps quit running just when spring runoff or heavy rain threatens basement flooding. The March 2025 ice storm demonstrated this perfectly when properties faced multi-day outages combined with flooding, creating conditions where homes became genuinely uninhabitable.
Winter outages create freeze risks. Without heating systems running, pipes can freeze within hours in Ontario's cold climate, causing thousands of dollars in burst pipe damage. Food spoils in refrigerators and freezers after several hours without power. Medical equipment becomes inoperable for residents with health needs. Home security systems go offline. For those running home businesses, extended outages mean lost productivity and income.
A backup generator provides peace of mind knowing your family and property stay protected regardless of grid failures. After experiencing a week-long outage, most homeowners consider generator installation essential rather than optional.
Types of Backup Generators
1. Whole-Home Standby Generators (Recommended)
Standby generators are permanently installed outside your home and automatically activate within seconds of a power outage—you won't even need to be home. They're connected to your home's natural gas or propane supply, so there's no refueling required.
Benefits of Standby Generators:
- ✓ Automatic operation – Turns on within 10-30 seconds of outage detection
- ✓ Whole-home power – Can power your entire home or selected critical circuits
- ✓ No refueling – Runs on natural gas or propane from your existing supply
- ✓ Weather protected – Enclosed in weatherproof housing designed for Canadian climates
- ✓ Quiet operation – Modern units are surprisingly quiet
- ✓ Home value – Increases property value and marketability
Typical sizing for Ontario homes: Homes under 1,000 square feet typically require 7 to 10 kW for essential circuits (furnace, refrigerator, lights, some outlets). The 1,500 square foot range needs 15 to 20 kW, the most common size that powers most home systems comfortably. Larger homes at 2,000+ square feet require 20 to 22 kW to power entire homes including central air conditioning.
Common brands available in the Ontario market include Generac (the most popular choice, with 9 to 22 kW residential models), Kohler (professional-grade units), Briggs & Stratton (consumer and residential grade), and Cummins (13 to 20 kW air-cooled models). All provide reliable backup power when properly sized and installed.
2. Portable Generator with Transfer Switch
Portable generators offer backup power at a lower upfront cost. With a properly installed transfer switch, you can safely power selected circuits in your home without dangerous extension cords running through windows.
Portable Generator Considerations:
- • Manual operation – You must be home to start the generator and connect it
- • Refueling required – Runs on gasoline, requires periodic refueling during extended outages
- • Storage needed – Must be stored when not in use (garage, shed)
- • Lower cost – Significantly less expensive than standby systems
- • Transfer switch required – Essential for safe operation (never backfeed your panel!)
I can install a transfer switch for your existing portable generator or help you select and install a complete portable backup system. A proper transfer switch installation is critical for safety and code compliance.
The Generator Installation Process
Generator installation is a comprehensive project involving electrical, gas, and potentially concrete work. Here's what to expect when working with Electric Al:
Step 1: Consultation & Load Calculation
I visit your property to discuss your backup power needs, calculate electrical loads, assess fuel source options (natural gas vs. propane), determine optimal generator placement, and recommend the right generator size for your needs and budget.
Step 2: Site Preparation
Standby generators require a level concrete pad and proper clearances from your home, windows, and property lines. I coordinate any necessary concrete work and ensure code-compliant placement. The generator should be positioned for optimal performance and minimal noise impact.
Step 3: Transfer Switch Installation
The transfer switch is the brain of your backup power system. It monitors utility power, signals the generator to start during an outage, and safely transfers electrical loads between utility and generator power. For standby systems, I install an automatic transfer switch. For portable generators, I install a manual transfer switch with a connection point outside your home.
Step 4: Electrical Installation
I run the necessary circuits from your panel to the transfer switch and from the transfer switch to the generator location. All wiring meets Ontario Electrical Safety Code requirements for generator installations, including proper grounding, bonding, and overcurrent protection.
Step 5: Fuel Connection
For natural gas generators, I coordinate with a licensed gas fitter to connect the generator to your gas service. For propane systems, connection is made to your existing tank or a dedicated generator tank. Proper fuel supply sizing is critical for reliable generator operation.
Step 6: Generator Startup & Programming
Once all connections are complete, I program the transfer switch settings, test automatic start functionality, verify all circuits function properly on generator power, ensure proper voltage and frequency, and conduct a simulated power outage to verify system operation.
Step 7: ESA Inspection & Final Testing
Generator installations require ESA inspection. I obtain all necessary permits and ensure the installation passes inspection. After final approval, I provide you with a complete demonstration and maintenance instructions.
Code Compliance & Safety
Generator installations must comply with the Ontario Electrical Safety Code, Ontario Building Code, and local bylaws. ESA notification (permit) is required for all hard-wired standby generators, with multiple inspection stages depending on complexity. The 2018 Code introduced mandatory Plan Review for standby generators serving life safety systems. Proper installation isn't optional; it's essential for safety, legal operation, and warranty protection.
Ontario-specific clearance requirements are strict and often surprise homeowners. Generators are classified as "arcing and sparking devices," requiring minimum 1 meter clearance from natural gas pressure relief valves and 3 meters from propane pressure relief valves. This significantly affects placement on properties with propane tanks. Generators also cannot be within these distances from other arcing devices like outdoor lights or receptacles. Gas lines buried in the same trench must maintain 300mm horizontal separation from electrical cables, and buried cable requires warning tape or surface markers from half-depth to surface.
Transfer switch requirements became more complex in the 2018 Code with the "separately derived system" concept. Four-pole transfer switches now isolate all neutrals, simplifying grounding by requiring system grounding only once at the source with no interconnection of hot or neutral conductors between utility and generator. Automatic Transfer Switches must be service-entrance rated for Canada; US-rated equipment is not acceptable. Meter-mounted transfer devices require Field Evaluation or UL1008M certification. Interlocks that mount to panel front covers, popular in the US, are not permitted in Canada.
⚠️ DANGER: Never Backfeed Your Panel
Some people are tempted to connect a portable generator directly to an outlet or dryer receptacle to power their home. This is extremely dangerous and illegal. Backfeeding can electrocute utility workers, cause fires, and destroy your generator and appliances. ALWAYS use a proper transfer switch installed by a licensed electrician.
Choosing the Right Generator Size
Generator sizing is critical. Too small and you won't be able to run essential equipment. Too large and you're paying for capacity you don't need. I perform detailed load calculations to recommend the right size for your home.
What Do You Want to Power?
This is the key question. Some homeowners want to power their entire home—central air, electric range, hot tub, and all. Others prioritize essentials: furnace, refrigerator, lights, and a few outlets. Your priorities determine the generator size you need.

Special Considerations for Our Region:
- • Well pumps – Common in rural Northumberland County; essential for backup power
- • Septic systems – Many newer systems have electric pumps requiring backup power
- • Cold climate – Heating is critical during winter outages; furnaces are priority #1
- • Basements – Sump pumps essential to prevent flooding during spring thaws and heavy rains
Generator Maintenance
Standby generators are like insurance: you hope you never need them, but when you do, they absolutely must work. The 2025 ice storm demonstrated that generators require proper maintenance. Many units that sat unused for years failed when desperately needed, creating emergency service calls during the height of the crisis. Proper annual maintenance ensures reliability when power failures strike.
Standby generators automatically run weekly self-tests (you'll hear them run for 10 to 15 minutes), exercising the engine, charging the battery, and verifying system operation. This automatic testing helps ensure readiness, but professional maintenance remains essential. Annual service includes oil changes, filter replacement, battery checks, and comprehensive system testing. Generator batteries typically last 2 to 3 years and should be replaced proactively to prevent failure during outages. Regular inspection for debris, damage, leaks, and proper clearances keeps units operating safely.
I offer maintenance service for generators I've installed and can provide recommendations for factory-authorized service providers for warranty maintenance. Annual maintenance contracts provide ongoing revenue while keeping your generator operational when needed most.
Generator Installation Costs
Generator installation is an investment in your home's resilience and your family's comfort. Costs vary significantly based on generator size, installation complexity, and fuel source.
What Does Generator Installation Cost?
Complete standby generator installations in Ontario typically range from $8,000 to $16,000 including the generator unit, automatic transfer switch, fuel connection, concrete pad, wiring, permits, and ESA inspection. This comprehensive price covers everything needed for a fully operational system. Smaller 7 to 10 kW systems fall toward the lower end, while larger 20 to 22 kW whole-home systems reach the higher range. Distance from house to generator location affects cable costs and can increase installation expenses.
Portable generator transfer switch installations cost $1,200 to $2,000 for the switch installation and connection point, plus the cost of the portable generator itself if needed ($800 to $2,500 depending on size). Portable systems provide backup power at significantly lower upfront investment but require manual operation and periodic refueling during extended outages.
What Affects Installation Cost?
- • Generator size: Larger units cost more but provide more backup capacity
- • Distance from panel: Longer wire runs increase costs
- • Concrete pad: Site preparation and pad installation
- • Gas line installation: New gas line or propane tank if needed
- • Transfer switch type: Automatic vs. manual, circuit capacity
- • Permits & inspections: ESA and municipal permits
Frequently Asked Questions
How long can a standby generator run continuously?
Modern standby generators can run for days or even weeks continuously as long as they have fuel. Natural gas and propane generators have essentially unlimited runtime since they're connected to your fuel supply. The limiting factor is typically maintenance needs—oil changes may be needed after 200-300 hours of runtime.
Will a generator power my whole house?
It depends on the generator size and your home's electrical load. A 22-26 kW generator can typically power an entire average home including central AC. Smaller generators (10-16 kW) power essential circuits. During your consultation, I'll calculate your loads and recommend the right size for your goals and budget.
How loud are standby generators?
Modern standby generators are surprisingly quiet—typically 60-70 decibels at 20 feet (about as loud as a normal conversation). Proper placement away from bedroom windows minimizes any noise concerns. Portable generators are significantly louder (70-80+ dB).
Natural gas vs. propane: which is better?
Natural gas provides continuous fuel supply with no refueling, making it ideal for urban and suburban areas served by gas distribution. If you have natural gas service, it's typically the most convenient option with unlimited runtime and lower operating costs. For homes without natural gas (common in rural Northumberland County), propane serves well but requires storage tanks and refills during extended outages. The 3-meter clearance requirement for propane versus 1-meter for natural gas affects installation planning and often determines generator placement on your property. Propane has higher energy content than natural gas, so generators may perform slightly better, but you'll need adequate tank capacity.
How often should I run my generator?
Standby generators automatically self-test weekly (usually for 12-15 minutes) to ensure they're ready when needed. This exercises the engine, charges the battery, and verifies system operation. You don't need to do anything—it's completely automatic.
Will a generator increase my home's value?
Yes, particularly in areas with frequent outages. A professionally installed standby generator is an attractive feature for home buyers and can provide good return on investment. It's especially valuable in rural areas and properties dependent on well water.
Can I install a generator myself?
No. Generator installations require a licensed electrician and ESA inspection. The electrical and gas work is complex and potentially dangerous if done incorrectly. Professional installation ensures safety, code compliance, warranty protection, and reliable operation.
What happens when power is restored?
Automatic transfer switches monitor utility power. When stable power returns, the switch transfers back to utility power and signals the generator to shut down. The transition is seamless—you might not even notice. The generator then enters a brief cool-down period before shutting off completely.
