Natural Gas Generator Ottawa: Is Standby Power Worth It?
In April 2023, an ice storm knocked out power for over 270,000 Hydro Ottawa customers — some for days. A year earlier, the May 2022 derecho left entire Ottawa neighbourhoods dark for nearly a week. And these so-called “100-year storms” are now happening every year.
If you’ve ever sat in a cold, dark house wondering when the power will come back on — or returned home to a basement full of water because your sump pump died, or thrown out hundreds of dollars in thawed food — you’ve probably thought about getting a home generator installation. But is it actually worth the investment?
For many Ottawa homeowners, the answer is a clear yes. A natural gas standby generator automatically powers your home within seconds of an outage, runs on your existing gas supply (so you never need to refuel), and protects everything from your furnace and fridge to your sump pump and security system.
At Gas Man Ottawa, we’ve installed standby generators across Ottawa, Kanata, Orleans, Barrhaven, Nepean, and surrounding areas. In this guide, we’ll help you decide whether a backup generator installation makes sense for your home — and what to expect if you move forward.

What Is a Natural Gas Standby Generator?
A natural gas standby generator is a permanently installed backup power system that sits outside your home, similar in size to a central air conditioning unit. It connects directly to your home’s natural gas line and electrical panel through an automatic transfer switch.
When Hydro Ottawa power goes out, the transfer switch detects the loss within seconds and signals the generator to start automatically — whether you’re home, at work, or on vacation. Power is restored to your home in as little as 10–30 seconds. When utility power returns, the generator shuts itself off and switches your home back to the grid. The entire process is automatic — no manual startup, no extension cords, no gasoline to store.
Because it runs on natural gas from your existing Enbridge supply, a standby generator can operate indefinitely during extended outages without refuelling. This is a major advantage over portable generators, which run on gasoline and typically last only 8–12 hours per tank.
Why Ottawa Homeowners Need Backup Power More Than Ever
Ottawa’s power grid faces increasing pressure from severe weather events, aging infrastructure, and growing demand. Here’s why standby generator installations have surged in popularity across the Ottawa region:
Severe Weather Is Increasing
Ottawa has experienced multiple devastating storms in recent years. Hydro Ottawa responded to over 1,150 outage events in 2023 alone. The April 2023 ice storm and May 2022 derecho demonstrated that extended multi-day outages are no longer rare — they’re becoming the new normal. Climate experts warn that the frequency and severity of these events will continue to increase.
Extended Outages Are Dangerous
A few hours without power is an inconvenience. Several days without power during an Ottawa winter is genuinely dangerous. Without electricity, your furnace can’t operate (even gas furnaces need electricity for the blower, ignition, and controls), your pipes can freeze and burst causing thousands of dollars in water damage, your sump pump stops running during spring melt or heavy rain, and your food spoils — a fully stocked freezer can represent $500–$1,000 in lost groceries.
Medical Equipment and Home Safety
If anyone in your household relies on powered medical equipment — CPAP machines, oxygen concentrators, home dialysis systems, or powered mobility devices — a backup generator isn’t a luxury, it’s a necessity. A standby generator also keeps your security system, exterior lighting, and garage door openers functional during an outage.
Remote Work Dependence
With more Ottawa residents working from home than ever, a power outage now means lost income and missed deadlines. A standby generator keeps your internet, computer, and home office running through any outage, allowing you to work without interruption while neighbours scramble for coffee shop WiFi.
Natural Gas vs. Propane vs. Portable: Which Generator Type Is Best?
Ottawa homeowners have three main generator options. Here’s how they compare:
| Feature | Natural Gas Standby | Propane Standby | Portable (Gasoline) |
|---|---|---|---|
| Startup | Automatic (10–30 seconds) | Automatic (10–30 seconds) | Manual — must be outside |
| Fuel Supply | Unlimited (utility gas line) | Limited to tank size | 8–12 hours per fill |
| Run Time | Indefinite | Days (depends on tank) | Hours only |
| Whole-Home Power | Yes (with proper sizing) | Yes (with proper sizing) | No — select circuits only |
| Installed Cost | $6,000–$15,000+ | $6,000–$15,000+ | $500–$3,000 |
| Refuelling | Never needed | Propane delivery required | Gasoline runs, storage hazard |
| Carbon Monoxide Risk | Low (installed outdoors) | Low (installed outdoors) | High if used improperly |
| Best For | Ottawa homes with natural gas | Rural homes without gas service | Occasional, short outages only |
For Ottawa homeowners connected to Enbridge natural gas, a natural gas standby generator is the clear winner. You already have the fuel supply running to your home — all that’s needed is a dedicated gas line from your gas system to the generator. No propane tank to maintain, no gasoline to store, and no limit on how long you can run during an extended outage.
How Much Does a Standby Generator Cost in Ottawa?
The total cost of a home generator installation in Ottawa includes the generator unit, automatic transfer switch, gas line connection, electrical work, and permitting. Here’s what to expect:
| Generator Size | Powers | Unit + Install Cost (Ottawa) |
|---|---|---|
| 10–14 kW (Partial Home) | Essential circuits: furnace, fridge, sump pump, lights, outlets | $6,000–$9,000 |
| 16–22 kW (Whole Home) | Entire home including AC, water heater, kitchen appliances | $9,000–$14,000 |
| 24–48 kW (Large Home) | Large custom homes with high electrical demand | $14,000–$20,000+ |
What’s Included in the Installation Cost?
A complete standby generator installation from Gas Man Ottawa includes the generator unit and concrete or composite mounting pad, automatic transfer switch wired to your electrical panel, dedicated natural gas line from your gas system to the generator, all electrical connections and testing, permit coordination where required, startup commissioning and homeowner walkthrough, and connection to manufacturer’s remote monitoring app.
Is a Generator Worth the Investment?
Consider what a single extended power outage can cost you: $500–$1,000 in spoiled food from the freezer and fridge, $5,000–$15,000+ in flood damage if your sump pump fails during spring melt or heavy rain, hundreds per day in lost income if you work from home, hotel costs if your home becomes unlivable in winter, and potential burst pipes causing $10,000+ in water damage during a winter outage.
A single catastrophic outage can easily cost more than the generator itself. For homeowners in flood-prone Ottawa areas, those with home offices, families with medical equipment needs, or anyone who experienced the 2022 or 2023 storms, a standby generator pays for itself in protection and peace of mind.
What Size Generator Does Your Ottawa Home Need?
Choosing the right generator size depends on how much of your home you want to power during an outage. Natural gas generators are measured in kilowatts (kW), and residential units typically range from 10 kW to 48 kW.
Essential Circuits (10–14 kW)
A partial-home generator powers your most critical systems: the furnace or heat pump, refrigerator, freezer, sump pump, select lights and outlets, security system, and internet/WiFi router. This is the most affordable option and protects against the biggest risks — frozen pipes, flooding, and food loss. It’s the right choice for most Ottawa homes on a moderate budget.
Whole-Home Power (16–22 kW)
A whole-home generator powers everything, including your central air conditioning, water heater, kitchen appliances (range, dishwasher, microwave), laundry machines, and all lights and outlets. During an outage, you won’t even know the power went out — everything operates normally. This is the most popular choice for Ottawa families who experienced multi-day outages and never want to go through that again.
How to Calculate Your Needs
The simplest approach is to list every appliance and system you want powered during an outage and add up their wattage requirements. However, this calculation is tricky because some appliances (like air conditioners and sump pumps) require significantly more power during startup than during steady operation. A Gas Man technician will perform a proper load assessment to ensure your generator is sized correctly — not too small (which risks overloading) and not too large (which wastes money on capacity you don’t need).

How a Natural Gas Generator Installation Works
The installation process for a standby generator involves coordination between gas fitting, electrical, and equipment setup. Here’s what to expect:
Step 1: Site Assessment and Sizing
A Gas Man technician visits your home to assess your electrical panel, determine the best generator location (following clearance requirements from windows, doors, and property lines), verify your gas meter capacity, and calculate the proper generator size based on your power needs.
Step 2: Equipment Selection and Ordering
Based on the assessment, we recommend a generator model and size that matches your home’s requirements. Popular brands include Generac, Kohler, and Briggs & Stratton, all available in natural gas configurations. We provide a detailed written estimate covering all equipment, labour, and permit costs.
Step 3: Concrete Pad and Generator Placement
A level concrete or composite pad is prepared at the installation site. The generator unit is positioned on the pad with proper clearances from your home’s exterior walls, windows, and air intakes.
Step 4: Gas Line Installation
Our TSSA-licensed gas fitters run a dedicated natural gas line from your home’s gas system to the generator. This includes a dedicated shut-off valve, proper pipe sizing for the generator’s BTU demand, and a thorough pressure test to verify there are no leaks. If your gas meter needs a capacity upgrade, we coordinate with Enbridge on your behalf.
Step 5: Electrical Connections
A licensed electrician installs the automatic transfer switch at your electrical panel and connects all wiring between the transfer switch and the generator. The transfer switch is the “brain” that detects outages and signals the generator to start.
Step 6: Testing and Commissioning
We simulate a power outage to verify the entire system works correctly — automatic startup, load transfer, proper voltage and frequency output, and automatic return to utility power. We then walk you through the system, explain the maintenance schedule, and set up remote monitoring on your phone.
Generator Maintenance: Keeping Your Backup Ready
A standby generator is only useful if it works when you need it. Regular generator maintenance is essential to ensure reliable operation during emergencies.
Weekly Self-Test
Most modern standby generators run an automatic self-test cycle once per week (typically for 10–15 minutes). This keeps the engine lubricated, charges the battery, and verifies the system is ready. You can usually set the test day and time through the generator’s control panel or monitoring app.
Annual Professional Service
Schedule professional generator maintenance once per year, ideally before storm season (late summer or early fall for Ottawa). A comprehensive service visit includes oil and filter changes, spark plug inspection and replacement, air filter cleaning or replacement, battery testing and terminal cleaning, coolant level check (on liquid-cooled models), fuel system inspection, transfer switch testing, and full load test under real operating conditions.
Oil Changes
Generator oil should be changed every 200–500 hours of operation, depending on the manufacturer’s recommendations. If your generator runs for several days during an extended outage, schedule a service call afterward to change the oil and inspect all components.
Gas Man Ottawa provides complete generator repair and maintenance services. Don’t wait until the next storm to find out your generator has an issue. Call (613) 880-3888 to schedule maintenance.
Common Questions Ottawa Homeowners Ask About Standby Generators
Before investing in a home generator installation, most Ottawa homeowners have practical concerns. Here are the questions we hear most often:
How Loud Is a Standby Generator?
Modern natural gas standby generators are significantly quieter than older models and portable generators. Most residential units operate at 60–70 decibels — comparable to a normal conversation or a dishwasher running. Many newer models feature sound-attenuated enclosures that bring the noise level below 65 dB. Ottawa noise bylaws are generally not an issue with properly installed standby generators.
Where Can the Generator Be Installed?
Generators must meet specific clearance requirements from windows, doors, air intakes, and property lines. The typical minimum setback is 5 feet from windows and doors, and 18 inches from the house wall. Your Gas Man technician will identify the optimal location during the site assessment, ensuring compliance with all local codes.
Will My Gas Meter Support a Generator?
A standby generator typically requires an additional 150,000–250,000 BTUs of gas capacity beyond your current household needs. If your current Enbridge gas meter can’t support the additional load, a meter upgrade will be needed. Enbridge typically handles meter upgrades at no charge to the homeowner, though the process can take several weeks. Gas Man coordinates this for you as part of the installation project.
Does a Generator Increase Home Value?
Yes. A professionally installed standby generator is a permanent home improvement that appeals to Ottawa buyers — especially after recent storm experiences. Real estate agents consistently report that homes with standby generators sell faster and often at a premium in Ottawa’s market, particularly in areas prone to outages like rural properties and heavily treed neighbourhoods.
Natural Gas Generator Safety
Standby generators are very safe when properly installed by licensed professionals. However, there are important safety considerations every homeowner should understand:
Carbon monoxide: Like any combustion appliance, generators produce carbon monoxide. Because standby units are permanently installed outdoors with proper clearances from windows and doors, the CO risk is minimal — far safer than portable generators, which cause hundreds of CO poisoning deaths across North America each year when people run them in garages or near open windows.
Gas line safety: The dedicated gas line to your generator is installed by TSSA-licensed technicians and pressure-tested just like any other gas appliance connection. An emergency shut-off valve allows you to quickly cut gas to the generator if needed. If you ever smell gas near the generator, follow the same safety protocol as any gas leak — evacuate and call Enbridge at 1-866-763-5427. Then contact Gas Man for a gas safety inspection.
Automatic transfer switch: The transfer switch physically disconnects your home from the utility grid before the generator begins powering your home. This prevents dangerous back-feeding of power into utility lines, which could electrocute Hydro Ottawa workers repairing downed lines.

Frequently Asked Questions: Natural Gas Generators in Ottawa
How much does a standby generator cost in Ottawa?
A complete natural gas standby generator installation in Ottawa typically costs between $6,000 and $15,000+, depending on generator size and installation complexity. A partial-home unit (10–14 kW) covering essential circuits runs $6,000–$9,000 installed, while a whole-home unit (16–22 kW) ranges from $9,000–$14,000 installed. Call Gas Man at (613) 880-3888 for a free in-home estimate.
How long can a natural gas generator run continuously?
A natural gas standby generator can run indefinitely because it draws fuel from your home’s Enbridge gas supply, which is not affected by power outages. As long as the natural gas utility is operating (and gas supply rarely goes out during electrical outages), your generator has unlimited fuel. You’ll just need to follow the manufacturer’s recommended oil change intervals during extended runs.
Is a natural gas generator better than propane?
For Ottawa homes connected to Enbridge natural gas, a natural gas generator is generally the better choice. You’ll never need propane deliveries, there’s no tank to maintain or refill, and your fuel supply is unlimited. Propane generators are an excellent option for rural Ottawa properties that don’t have natural gas service.
Do I need a whole-home generator or will a partial-home unit work?
A partial-home generator (10–14 kW) that covers essentials — furnace, fridge, sump pump, lights, and key outlets — is sufficient for most Ottawa families. If you want to also power your air conditioning, electric range, water heater, and all circuits during an outage, a whole-home generator (16–22 kW) is the better choice. A Gas Man technician can help you determine the right size based on your priorities and budget.
How often does a standby generator need maintenance?
Standby generators require annual professional maintenance including oil and filter changes, spark plug inspection, battery testing, and a full load test. The generator also runs a brief automatic self-test weekly to stay ready. After extended operation (such as a multi-day outage), schedule a service call for an oil change and inspection.
Will a generator installation require a gas meter upgrade?
Possibly. If your current gas meter can’t support the additional BTU demand of the generator, Enbridge will need to upgrade it. This is typically done at no cost to the homeowner, but it can take several weeks to schedule. Gas Man coordinates the meter upgrade as part of your generator installation project.
Can Gas Man repair generators from any brand?
Yes. Gas Man Ottawa’s technicians are experienced with all major generator brands including Generac, Kohler, and Briggs & Stratton. We provide generator repair, diagnostics, and parts replacement for residential standby units across the Ottawa region.
What happens to my generator in winter?
Natural gas standby generators are designed for year-round outdoor operation, including Ottawa’s harsh winters. The generator enclosure protects internal components from snow, ice, and extreme cold. Most units include a built-in engine block heater that keeps the engine warm and ready for instant startup even in -30°C conditions. Just ensure the area around the generator is kept clear of snow drifts so exhaust can vent properly.
Don’t Wait for the Next Storm
Every year, Ottawa homeowners say the same thing after a major power outage: “I should have gotten a generator.” The best time to install one is before you need it — not when the next ice storm or derecho is already bearing down.
Gas Man Ottawa makes the process simple. We’ll assess your home, recommend the right generator size, handle the gas line installation, coordinate electrical work, and commission the system so it’s ready to protect your family the moment the power goes out.
