Denver Foothills Power Outages Leave Over 120,000 Without Electricity — Homes With Backup Generators Stayed Online

Recent power outages across the Denver foothills left more than 120,000 residents without electricity, affecting communities including :contentReference[oaicite:0]{index=0}, :contentReference[oaicite:1]{index=1}, and large portions of :contentReference[oaicite:2]{index=2}.

While many homes experienced hours—or in some cases days—without power, homeowners equipped with standby backup generators reported little to no disruption.

What Caused the Denver Foothills Power Outages?

Power outages in the Denver foothills are increasingly common due to a combination of:

• Heavy, wet snow accumulating on power lines
• High winds causing tree and branch failures
• Wildfire mitigation shutoffs in foothill zones
• Remote terrain that slows utility restoration

Unlike urban areas of :contentReference[oaicite:3]{index=3}, foothill communities often face longer restoration times because power lines run through forested and mountainous terrain.

Why Homes With Backup Generators Did Not Lose Power

Homes equipped with automatic standby generators continued operating normally during the outage. These systems are permanently installed and designed to activate within seconds of a utility failure.

Key reasons generator-equipped homes stayed online:

• Automatic transfer switches detected the outage instantly
• Natural gas or propane fuel remained available
• Proper load sizing ensured heating systems could start
• No manual setup required, unlike portable generators

Why Backup Generators Matter More in the Denver Foothills

Backup generators are not a luxury in foothill communities—they are increasingly viewed as critical infrastructure for the home.

• Electricity powers furnaces, boilers, and heat pumps
• Well pumps require power for water access
• Internet and cellular boosters rely on electricity
• Medical devices and refrigeration depend on uninterrupted power

During the recent outage, homeowners with whole-house generators reported no loss of heating, lighting, or basic daily functionality.

Essential-Load vs Whole-Home Backup Power

Not every home requires full-house coverage. Many foothills homeowners choose essential-load backup generator systems, which power:

• Heating equipment
• Refrigerators and freezers
• Lighting and outlets
• Well pumps or sump pumps

Whole-home generator systems, on the other hand, are sized to power nearly everything, including electric ranges, HVAC systems, and larger homes common in Evergreen.

Are Power Outages in the Denver Foothills Becoming More Common?

Data and homeowner experience suggest that foothill outages are becoming more frequent due to climate-driven weather extremes and increased wildfire mitigation strategies.

As a result, more homeowners are proactively installing standby generators in Evergreen, Golden, and Jefferson County rather than reacting after a major outage.
