A whole-house backup generator for rural New Brunswick typically runs $15,000-$35,000 installed, with most homeowners spending around $20,000-$25,000 for a quality system that handles essential circuits plus heating.
Given New Brunswick's frequent power outages — especially in rural areas during ice storms, nor'easters, and summer thunderstorms — a standby generator is often considered essential infrastructure rather than luxury. Standby generators (10-22 kW) are the most practical choice for rural properties, automatically starting within seconds of an outage and running on propane or natural gas.
System sizing depends on your home's electrical load. A 10-12 kW unit ($8,000-$12,000 equipment cost) handles essential circuits: furnace/heat pump, well pump, refrigeration, some lighting, and a few outlets. A 16-20 kW system ($12,000-$18,000 equipment) can power most of your home including electric water heater, multiple zones of heating, and most appliances. For homes with electric heating, central air, or large well pumps, you'll need 20-24 kW ($15,000-$22,000 equipment).
Installation costs add $5,000-$12,000 depending on complexity. This includes the concrete pad, electrical transfer switch installation, gas line connection, and permits. Rural installations often cost more due to longer propane runs, challenging access for concrete trucks, and the need for larger propane tanks (500-1,000 gallons typically required).
All electrical work must be done by a TIS-licensed electrical contractor with an NB Power wiring permit (1-800-615-0522). Gas connections require a TIS-licensed gas fitter with proper permits. Since you're in rural NB, you'll need a building permit from your Regional Service Commission — contact your local RSC office as permit requirements vary by area.
Propane is the fuel of choice for most rural NB installations since natural gas isn't available outside urban centers. Expect $2,000-$4,000 for a 500-gallon propane tank installation. A 20 kW generator consumes roughly 3-4 gallons per hour at full load, so a 500-gallon tank provides 5-7 days of continuous runtime.
Maintenance is crucial — annual service runs $300-$500 and includes oil changes, filter replacement, and load testing. Quality brands like Generac, Kohler, and Cummins offer the best parts availability and service networks in Atlantic Canada.
Your next step is getting a load calculation from a licensed electrical contractor to properly size the system, then obtaining quotes from generator dealers who handle the complete installation including permits and gas connections.
