Backup Power Solutions
Colorado Power Outages Don't Have to Mean Dark, Cold, Disconnected Nights
Winter storms, high winds, and aging grid infrastructure mean power outages in the Denver metro are a real and recurring problem. A whole-home standby generator kicks on automatically within seconds of an outage — your furnace, refrigerator, lights, and medical equipment keep running without you lifting a finger. Battery backup systems offer a quieter, fuel-free alternative for shorter outages or for powering specific critical loads. Done’s licensed electricians have been installing backup power systems in Colorado homes since 1999, and we’ll help you choose the right solution for your home’s size, critical loads, and budget.
From the transfer switch to the final connection, we handle every part of the electrical installation. See our full electrical services lineup or call 833-539-9153 to schedule a backup power assessment.
- Automatic Standby Power Whole-home generators sense an outage and start automatically — no running to the garage, no extension cords, no manual switching.
- Battery Backup Options For quieter, fuel-free backup power, battery systems like the Generac PWRcell store energy and deliver it silently when the grid fails.
- Whole-Home Coverage We size and install systems that power your entire home — not just a few outlets — so your family stays comfortable through any outage.
Is Backup Power Right for You?
Signs Your Home Should Have a Generator or Battery System
Not every home needs a standby generator, but some situations make backup power less of a luxury and more of a necessity.
-
Frequent Winter Outages
If your neighborhood loses power during major snowstorms, a standby generator means your furnace, water heater, and lights stay on no matter how long the outage lasts.
-
Medical Equipment at Home
CPAP machines, oxygen concentrators, and other home medical devices cannot safely lose power. Backup power is an essential safety measure, not a convenience.
-
Working from Home
If an outage means lost income or missed deadlines, a standby generator pays for itself quickly. Keep your internet, devices, and home office running without interruption.
-
Concern About Food and Pipe Loss
A long outage in winter risks frozen pipes. In summer, a refrigerator full of food can be lost in hours. Standby power eliminates both risks.
What We Install
Backup Power Systems Done Installs and Services
Done installs and services a full range of backup power solutions, sized and configured for your home's specific needs.
- Whole-Home Standby Generators Natural gas or propane-powered generators that start automatically during an outage and run your entire home. We install and connect the transfer switch, fuel line, and all electrical connections.
- Battery Backup Systems Whole-home battery systems store energy from the grid or solar panels and discharge silently during outages. Ideal for shorter outages or for pairing with solar.
- Transfer Switch Installation A properly installed automatic transfer switch is the heart of any standby system. We install whole-home and load-center transfer switches to current code.
- Generator Maintenance Standby generators need regular exercise and maintenance to start reliably when you need them. We offer service and tune-up visits to keep your system ready.

Tyler was very personable, informative, and cleaned up after. He went over what work was needed and price, then showed me what was done.
Disconnected hard wiring to dishwasher; replaced outlet under sink with surge protector outlet.

I cannot say enough good things about Caedon and Tyler! They came out to fix a plug for us and were the definition of professional and skilled. They were patient, incredibly thorough and detailed with their work, and knew exactly how to get the job done efficiently. To top it all off, they left the area brilliantly clean when they were finished. Exceptional service from two fantastic gentlemen - highly recommend!

Frequently Asked Questions
What's the difference between a standby generator and a portable generator?
A standby generator is permanently installed outside your home, connected to your electrical panel via a transfer switch, and starts automatically during an outage. A portable generator requires manual setup and extension cords and cannot safely connect to your home’s wiring. For whole-home protection, standby is the right choice.
How large of a generator do I need for my home?
Generator sizing depends on your home’s square footage and which circuits you need to power. A whole-home system for a typical Denver-area home generally falls between 14kW and 24kW, but we calculate this precisely based on your actual load — not a rough estimate.
Can a battery backup system power my whole home?
Most current battery systems are better suited to critical loads — furnace, refrigerator, lights, devices — rather than running a whole home indefinitely. For multi-day whole-home coverage, a standby generator is typically the stronger choice. We’ll help you weigh the options honestly based on your situation.
Is a permit required to install a standby generator?
Yes. Generator installations require an electrical permit and in most cases a gas permit as well. Done handles both permit applications and coordinates the required inspections. This protects your home and is required for homeowner’s insurance purposes in most cases.
