When the power goes out on a cold Okanagan evening, a few questions quickly come to mind. Will the furnace keep running? How long will the refrigerator stay cold? Will the internet, lights and other essentials continue working?
For homeowners throughout Kelowna, West Kelowna, Lake Country, Peachland and the rest of BC, having reliable backup power can provide valuable peace of mind.
But which solution makes the most sense?
Portable power stations, fuel-powered generators and home battery backup systems all have their advantages. And when batteries are paired with solar panels, they can offer benefits that extend well beyond occasional power outages.
This guide explores how the different options compare, what they can realistically power, and what to consider before investing in a backup energy system.
Understanding Your Home Backup Power Options
There are three common approaches to residential backup power.
Portable Power Stations
A portable power station is essentially a rechargeable battery with built-in electrical outlets.
These units are generally designed to power smaller appliances and electronic devices during short outages. They're also popular for camping and recreational use.
Some models can be recharged using portable solar panels, although solar charging performance depends on available sunlight and equipment capacity.
Best suited for: Short outages, essential electronics, renters and homeowners who want a portable solution without permanent installation.
Fuel-Powered Generators
Generators produce electricity using an engine powered by gasoline, propane, natural gas or another suitable fuel.
Portable generators are commonly used for temporary backup power, while permanently installed standby generators can be designed to start automatically when utility service is interrupted.
Properly sized generators can support larger electrical loads, including water pumps, refrigeration and some heating equipment.
However, they require fuel, maintenance and appropriate outdoor installation or operating locations.
Best suited for: Extended outages, larger electrical demands, rural properties and homeowners who need dependable power when solar generation is limited.
Home Battery Backup Systems
A permanently installed home battery stores electricity for use when needed.
Depending on the equipment and electrical configuration, a battery system can automatically supply selected household circuits during a power outage.
Home batteries may be charged from the utility grid or integrated with solar panels.
When paired with a properly configured solar installation, batteries can store electricity generated during the day and potentially recharge during an outage when sunlight is available.
Best suited for: Homeowners seeking quiet backup power, automatic operation, reduced dependence on fuel and potential everyday benefits from solar energy storage.
What Can Each Backup System Actually Power?
Before choosing equipment, it's important to identify which appliances and systems need to remain operational when the power goes out.
Common priorities include:
Refrigerators and freezers.
Essential lighting.
Internet routers and communications equipment.
Furnace fans and heating controls.
Well pumps and sump pumps.
Phone and electronic device charging.
Medical equipment requiring uninterrupted electrical power.
Some of these loads require considerably more electricity than others.
A refrigerator may consume relatively little energy over a full day, but its compressor can require a higher burst of power when starting.
Water pumps and other motor-driven equipment can create similar demands.
Electric resistance heating, electric water heaters and EV charging can require substantially more power than basic household essentials.
For that reason, backup systems are often designed around a critical-load panel, supplying selected circuits rather than the entire home.
A qualified installer can help determine which circuits should receive backup power and how much equipment capacity is required.
For life-sustaining medical equipment, backup arrangements should follow the equipment provider's guidance and include an appropriate contingency plan.
How Long Will Backup Power Last?
Runtime is one of the most important considerations when comparing backup options.
For a battery system, runtime depends primarily on usable storage capacity and the amount of electricity being consumed.
For example, a battery with 10 kWh of usable storage supplying an average 500-watt load would theoretically provide approximately 20 hours of operation before accounting for system losses, reserve settings and other operating conditions.
Actual runtime will vary.
A larger battery or smaller electrical load can extend operating time, while high-demand appliances can reduce it considerably.
Portable power stations follow the same basic principle, although their storage capacity is often smaller.
Generators operate differently. Their runtime depends on fuel availability, consumption rate and the electrical load being supplied.
A natural-gas standby generator may offer extended operation where gas service remains available. Propane and gasoline generators depend on stored fuel and the ability to replenish it.
The key question isn't simply how long a system can run. It's how much electricity you need during that time.
A system designed to keep essential appliances operating overnight is very different from one intended to support an entire home through a multi-day winter outage.
Batteries vs. Generators: Comparing the Trade-Offs
Both technologies can provide reliable backup power when properly designed and installed.
Consideration | Home battery | Generator |
|---|---|---|
Noise | Very quiet | Produces engine noise |
Fuel | No combustion fuel | Requires a suitable fuel supply |
Routine maintenance | Generally limited | Engine servicing required |
Automatic backup | Available with suitable equipment | Available with standby systems |
Extended outages | Limited by storage and available recharging | Limited by fuel and equipment capability |
Heavy electrical loads | Depends on inverter and battery capacity | Depends on generator capacity |
Solar integration | Common with compatible systems | Possible in hybrid designs |
Typical upfront investment | Often higher for substantial storage | Varies; portable units can cost less, standby installations more |
Neither solution is automatically better.
A generator can be particularly valuable during prolonged outages when heating, pumping or other substantial loads must remain operational.
A battery system offers quiet operation, no exhaust and potentially greater convenience for frequent shorter outages.
For some properties, combining battery storage with a generator may provide the most practical balance of reliability and operating flexibility.
Why Solar-Plus-Battery Backup Is Worth Considering
One of the advantages of pairing a home battery with solar panels is that the system can provide value beyond emergency power.
During normal operation, solar panels generate electricity that can be used in the home.
Where supported by the system's controls, surplus generation can be stored in the battery for later use.
This allows homeowners to consume more of their own solar electricity during evenings or other periods when panel production is lower.
Depending on the utility rate structure, system design and household consumption, this may reduce electricity purchases from the grid.
During an outage, a properly configured solar-plus-battery system may also continue supplying backup circuits and recharge its batteries when sunlight is available.
However, not every solar installation automatically provides backup power.
Conventional grid-connected solar systems typically shut down during utility outages for safety reasons. Maintaining power during an outage requires compatible backup equipment and approved electrical isolation from the grid.
Solar production is also weather-dependent. During prolonged winter storms, available generation may be insufficient to replenish the battery.
A realistic backup design must account for these limitations.
For homeowners interested in solar energy, battery storage can be a valuable addition, provided the system is designed around actual electrical needs and expectations.
Understanding BC Hydro and FortisBC Requirements
An important consideration for Okanagan homeowners is identifying their electricity provider.
Depending on the property, electricity service may be supplied by BC Hydro or FortisBC.
FortisBC also supplies natural gas in parts of British Columbia, but natural gas service and electricity service are separate. A home with a FortisBC gas account may receive its electricity from either utility, depending on location.
The distinction matters when considering solar installations, grid interconnection, electricity credits and incentive programs.
BC Hydro Customers
BC Hydro offers solar and battery incentives for qualifying grid-connected residential customers.
Under the battery rebate rules introduced in April 2026, eligible battery systems enrolled in BC Hydro's Peak Saver program may qualify for incentives with or without solar panels.
Other eligible batteries may qualify for different rebate amounts when paired with solar generation.
Eligibility depends on the equipment, property, program conditions and required approvals.
Homeowners should confirm current requirements directly through BC Hydro's solar and battery rebate program.
FortisBC Electricity Customers
FortisBC operates a separate Net Metering Program for eligible customers generating renewable electricity.
Its program rules, interconnection requirements and electricity credits differ from BC Hydro's arrangements.
FortisBC electricity customers are not eligible for BC Hydro's residential solar and battery rebates.
Homeowners should confirm whether any other applicable incentives, pilots or financing programs are available rather than assuming the same rebates apply throughout British Columbia.
Regardless of the electricity provider, interconnection approvals and electrical safety requirements should be reviewed before equipment is purchased or installed.
Preparing for an Okanagan Winter Power Outage
Winter introduces several challenges that can influence backup power performance.
Shorter days, snowfall and cloud cover reduce the electricity available from solar panels.
Cold temperatures can also affect battery performance, particularly when equipment is installed outside its recommended operating temperature range.
Modern battery systems may incorporate thermal management, but proper equipment selection and placement remain important.
Generators face their own winter considerations, including fuel storage, starting reliability, ventilation and access during heavy snowfall.
For homes heated with natural gas or propane, it's worth remembering that many modern furnaces still require electricity for fans, controls and ignition systems.
A home may have an available fuel supply but still lose heating when the electrical power fails.
That makes heating-system controls and circulation equipment important considerations when establishing critical backup loads.
For rural properties with well pumps, private water systems or other essential equipment, backup planning may be even more important.
A suitable system should be designed around realistic winter conditions, not simply ideal summer performance.
Safety and Professional Installation Matter
Backup power equipment must be installed and operated safely.
Fuel-powered generators produce carbon monoxide, an invisible and potentially deadly gas.
Portable fuel-burning generators must never be operated inside a home, garage, shed or other enclosed space.
Health Canada recommends operating portable generators at least 6 metres (20 feet) from buildings, with exhaust directed away from windows, doors and ventilation openings.
Permanently connecting a generator or battery system to household electrical circuits requires properly designed transfer, isolation and protection equipment.
Improper connections can create serious electrical hazards, including the risk of energizing utility lines during an outage.
In British Columbia, regulated electrical installations generally require permits and must comply with applicable electrical codes and inspection requirements.
Technical Safety BC provides information about electrical permitting, although some municipalities administer their own inspection programs.
Working with qualified installation professionals helps ensure the selected system meets the property's electrical requirements and applicable safety standards.
Which Backup Power Solution Makes the Most Sense?
The right choice depends on what you need the system to accomplish.
Choose a portable power station when:
You want an affordable, portable way to power a limited number of devices during relatively short outages.
Consider a generator when:
You need to support substantial electrical loads or remain operational through extended outages, and you have a reliable fuel supply.
Consider a home battery system when:
You value quiet operation, automatic backup and the convenience of avoiding fuel handling and routine engine maintenance.
Consider solar paired with battery storage when:
You want outage protection along with the potential benefits of generating and storing your own electricity throughout the year.
Some homeowners may benefit from combining technologies, particularly on rural properties or where extended outages are a concern.
Before investing, it's worth reviewing your household's critical loads, electrical service, budget and expectations with someone who understands the available options.
Conclusion: Plan Backup Power Around Your Home
There's no single backup power solution that's right for every BC homeowner.
Portable power stations offer simplicity and flexibility. Generators provide dependable power for larger loads and extended outages when fuel is available. Home batteries provide quiet, convenient backup, and solar-integrated systems can deliver additional benefits during everyday operation.
