Power failures hit different on a rural lot: no power means no well pump, which means no water, and in winter it means a race against the furnace. That's why whole-home standby generators are close to standard equipment on estate properties here — and why the 2018 tornado and the 2022 derecho turned waiting lists into a fixture. Here's what installation actually costs and how sizing works when a well pump is on the panel.
| 16 kW standby unit (installed, propane) | $8,000 – $13,000 |
| 22–26 kW standby unit (installed) | $11,000 – $17,000 |
| Portable generator + manual interlock | $1,500 – $3,500 |
| Automatic transfer switch (if quoted separately) | $1,500 – $3,000 |
| ESA and TSSA permits | $150 – $500 |
| Concrete pad / propane line run (each) | $500 – $1,500 |
| Cold-weather kit | about $250 |
| Propane tank rental (annual) | $100 – $250 / yr |
| Annual maintenance plan | $200 – $450 / yr |

Sizing for a rural home
The number that matters is surge load, not running load. A submersible well pump can draw 2–3x its running wattage at start-up, and if the generator can't carry that spike plus the furnace, you'll get brownout trips at the worst time. For most 3,000+ sq ft homes here with a well pump, electric appliances, and a heat pump or AC, 22–26 kW is the honest spec; 14 kW works for smaller homes with gas heat and careful load management.
Fuel, permits, and lead times
Propane dominates outside the village: a rented 500-gallon tank runs a standby unit for days of continuous outage. Installation needs an electrical permit (ESA) and, for propane, TSSA-compliant fuel work — reputable installers bundle both. Lead times stretch after every major storm; ordering in a calm season is the difference between a three-week install and a three-month wait.
Common questions
How much does a whole-home generator cost installed near Ottawa?
In 2026, a propane standby generator installed on a rural Ottawa home typically runs $12,000–$16,000 for 14 kW and $16,000–$24,000 for 22–26 kW, including transfer switch and fuel hookup.
What size generator do I need if I'm on a well?
Size for the well pump's start-up surge, not its running load. Most larger Manotick homes with a submersible pump land at 22–26 kW; undersizing is the most common rural installation mistake.
Propane or natural gas?
Outside the Manotick village core, natural gas service is limited, so most estate-lot installs run on rented propane tanks — about $100–$250 per year in tank rental plus fuel used.
Do standby generators need permits?
Yes — an ESA electrical permit, and TSSA-compliant work on the propane side. Established installers handle both as part of the quote.
