The power flickers. Then it goes out completely. In the San Bernardino Mountains, this isn't a rare occurrence—it's a regular reality of mountain living. Heavy snow, ice storms, fallen trees, and high winds can knock out electricity in Lake Arrowhead, Blue Jay, Crestline, and Running Springs for hours or even days.
While you can't control when storms hit, you can control how they affect your home. A whole-home backup generator transforms power outages from major disruptions into minor inconveniences.
Power Outages in Lake Arrowhead: The Real Cost
Mountain communities face more frequent and longer power outages than valley residents. When the grid goes down at 5,000+ feet elevation during winter, the stakes are higher:
Immediate Concerns:
Frozen pipes from loss of heating
Spoiled food from refrigerator/freezer failure
No water (if you have a well pump system)
Security system shutdown
Medical equipment failure
Unsafe conditions for elderly or vulnerable family members
Long-Term Damage:
Burst pipes causing thousands in water damage
HVAC system damage from freezing temperatures
Insurance claims and deductibles
Temporary housing costs while repairs are made
Lost work productivity
The average Lake Arrowhead power outage costs homeowners $500-2,000 when you factor in spoiled food, damaged pipes, hotel stays, and lost productivity. A single major outage can cost more than your generator installation.
Whole-Home Generators vs. Portable Generators: What Lake Arrowhead Homeowners Need to Know
Portable Generators: The Budget Option (With Major Drawbacks)
Portable generators cost less upfront ($400-1,500), but they come with significant limitations for Lake Arrowhead homes:
Limitations:
Manual setup every time power fails (often in freezing, dark conditions)
Limited capacity (can't power whole home)
Requires fuel storage and regular refueling
Carbon monoxide risks if not properly ventilated
No automatic operation (useless if you're away from your property)
Noisy operation
Requires extension cords creating trip hazards

Occasional weekend cabin use
Temporary solution while planning whole-home installation
Budget constraints preventing permanent installation
Very small cabins with minimal electrical needs
Whole-Home Backup Generators: Complete Power Security
Permanent backup generators install outside your Lake Arrowhead home and connect directly to your electrical panel through a transfer switch.
Advantages:
Automatic operation: Power restores within 10-30 seconds of outage
Complete coverage: Powers entire home including HVAC, appliances, lighting
Runs on natural gas or propane: No fuel storage or refilling needed
Operates while you're away: Protects vacation homes and part-time residences
Increases property value: Major selling point for mountain real estate
Quieter operation: Enclosed units with sound dampening
Weather-protected: Built for mountain conditions
Weekly self-testing: Ensures readiness when you need it
Investment Range:
Equipment and installation: $5,000-15,000 depending on home size and fuel type
Ongoing costs: Minimal (annual maintenance $150-300)
For Lake Arrowhead homeowners, whole-home generators aren't luxury items—they're practical investments that pay for themselves by preventing damage and maintaining comfort during inevitable mountain outages.
Sizing Your Generator: How Much Power Does Your Lake Arrowhead Home Need?
Generator sizing is critical. Too small and it won't power essential systems. Too large wastes money on unnecessary capacity.
Essential Load Calculation
A licensed electrician evaluates your home's specific needs, but here are general guidelines:
Small Cabin (under 1,500 sq ft):
Generator size: 10-12 kW
Powers: Refrigerator, furnace, lights, well pump, some outlets
Fuel type: Propane (most mountain homes)
Installation cost range: $5,000-8,000
Medium Home (1,500-2,500 sq ft):
Generator size: 14-20 kW
Powers: Full HVAC, all appliances, lighting, outlets, security systems
Fuel type: Propane or natural gas (if available)
Installation cost range: $7,000-12,000
Large Home (2,500+ sq ft):
Generator size: 22-30 kW
Powers: Everything including hot tub, additional HVAC zones, garage
Fuel type: Propane or natural gas
Installation cost range: $10,000-15,000+
Critical Circuits for Mountain Homes
Even with a properly sized generator, prioritizing critical circuits ensures efficient operation:
Must-Have:
Heating system (furnace blower, baseboard heaters)
Well pump (if applicable)
Refrigerator and freezer
At least one bathroom
Kitchen outlets
Security/communication systems
Should-Have:
All HVAC zones
Water heater
Laundry
Garage door opener
Outdoor lighting
Nice-to-Have:
Hot tub/spa
Electric vehicle charger
Workshop/garage outlets
All lighting circuits
Your electrician will design a load management system ensuring critical circuits receive power first, with additional capacity available for comfort systems.
Natural Gas vs. Propane Generators for Lake Arrowhead
Propane Generators: The Mountain Standard
Most Lake Arrowhead properties use propane for backup generators because natural gas infrastructure is limited in mountain communities.
Propane Advantages:
Available throughout mountain areas
Tanks already exist for heating/cooking
Reliable fuel supply (not grid-dependent)
Can add larger tank for extended runtime
Clean burning with minimal maintenance
Propane Considerations:
Requires adequate tank capacity (recommend 500-1,000 gallon tank)
Tank refills needed during extended outages
Fuel costs vary seasonally
Tank placement requires space and access
Runtime Examples (20 kW generator at 50% load):
250-gallon tank: ~24 hours
500-gallon tank: ~48 hours
1,000-gallon tank: ~96 hours
For most Lake Arrowhead outages (12-48 hours), a 500-gallon propane tank provides adequate fuel with buffer capacity.
Natural Gas Generators: Limited But Ideal When Available
Some Lake Arrowhead neighborhoods have natural gas infrastructure, making it the preferred fuel source.
Natural Gas Advantages:
Unlimited runtime (as long as gas service continues)
No refueling ever needed
Lower fuel costs than propane
No tank space requirements
Simpler installation
Natural Gas Limitations:
Not available in most mountain areas
Depends on utility infrastructure (can fail during disasters)
Requires adequate gas line capacity
If your Lake Arrowhead property has natural gas service, verify the line can support both your home's existing gas appliances AND generator demand simultaneously.

Common Lake Arrowhead Generator Questions
Q: Will my generator work during heavy snow?
A: Yes. Generators include weather-resistant enclosures designed for mountain conditions. Snow accumulation should be cleared from around the unit (maintain 3-foot clearance), but the generator will start and run in freezing temperatures. Most include cold-weather starting packages for reliable operation down to -20°F.
Q: How long can a generator run continuously?
A: Whole-home generators are designed for extended operation. With proper fuel supply, they can run indefinitely. However, most Lake Arrowhead outages resolve within 12-72 hours. The limiting factor is typically fuel capacity (propane) rather than generator capability.
Q: Will my generator power my entire house?
A: It depends on generator sizing and your home's electrical load. Properly sized generators power all essential systems and most comfort systems. Very large homes may require load shedding (automatically managing which circuits receive power) during peak demand, but critical systems always maintain power.
Q: How loud are backup generators?
A: Modern residential generators operate at 60-70 decibels (similar to normal conversation or dishwasher). This is significantly quieter than portable generators. Placement away from bedrooms and neighbor proximity further reduces noise impact.
Q: Can I install a generator myself to save money?
A: No. California law requires licensed electricians to install transfer switches and make electrical connections. Propane work requires licensed gas fitters. DIY installation voids warranties, violates building codes, creates insurance issues, and poses serious safety risks including carbon monoxide poisoning and electrical fires.
Q: What happens to my generator when power is restored?
A: The transfer switch automatically detects utility power restoration, allows a brief stabilization period (avoiding voltage spikes), then transfers your home back to grid power. The generator runs a short cool-down period, then automatically shuts off. The entire process is seamless—you may not even notice the transition.
Q: Do generators require special insurance?
A: Your existing homeowner's insurance typically covers permanently installed generators. However, inform your insurance company about the installation. Some insurers offer premium reductions because generators prevent freeze damage and reduce claim likelihood.
Q: How do generators affect property value?
A: Backup generators significantly increase Lake Arrowhead property values. Buyers view them as essential infrastructure for mountain living, similar to well pumps or septic systems. Expect to recoup 70-90% of installation costs in increased property value, with full cost recovery in high-demand markets.
Real Lake Arrowhead Generator Success Stories
The Vacation Home Owner
"We're only at our Lake Arrowhead cabin every other weekend. Last winter, we were in Orange County when a major storm knocked out power for 4 days. Our neighbors' pipes froze and burst—$15,000 in damage. Our generator kicked on automatically, kept the heat running, and we didn't have a single problem. Best $8,500 we ever spent." - Mark T., Blue Jay
