Standby generator installation is what separates the houses that ride out an outage from the ones scrambling for flashlights. Xcel now shuts power off on purpose when high winds raise fire risk, and Front Range blizzards still take lines down the old fashioned way. When the grid drops, a standby generator senses it and has your whole house back in about 10 seconds. Furnace, well pump, sump pump, fridge, wifi, medical equipment, all of it, with no cords, no gas cans, and no need to be home. One call gets you a fixed quote covering sizing, gas, wiring, permit, and startup.
A standby generator install is a gas, electrical, and code project rolled into one. You get one crew and one fixed number for all of it:
Outages here are no longer rare weather trivia. Xcel has started shutting off power on purpose when high winds raise wildfire risk, and those shutoffs can outlast the storm that caused them. Add spring blizzards, summer microbursts, and the long co-op lines east of I-25, and losing power a few times a year is now the normal case, not the exception.
The real cost is not the dark house. It is the furnace that quits at ten below and the pipe that bursts behind the drywall. It is the sump pump sitting dead through a wet spring, the well pump that stops feeding the house, and the work from home days you cannot afford to lose. A standby generator makes all of that handle itself, whether you are home or on a plane.
Most whole home standby generator installations in the Denver metro land between $13,000 and $22,000 installed, depending on unit size, gas line length, and panel condition. Essential circuit setups cost less. You get one fixed number after a walkthrough, and it covers the generator, gas, electrical, permit, and startup. No allowances that balloon later.

Once your unit is on hand, the physical install typically takes one to two days, with the inspection right behind it. We are based in Brighton and install standby generators across the Denver metro and the Front Range, including Thornton, Westminster, Commerce City, Fort Lupton, and the acreage properties east of I-25 where outages hit hardest and last longest.
How much does standby generator installation cost?
Most whole home systems in the Denver metro run $13,000 to $22,000 installed, less if you only need essential circuits covered. The quote is fixed after a walkthrough and includes gas, electrical, permit, and startup.
Will it really run my whole house?
If it is sized right, yes. We run a load calculation before quoting, so the furnace, well pump, kitchen, and AC are actually covered instead of finding out what is missing during the first outage.
Do you handle the permit and inspection?Yes. We pull the permit, meet the inspector, and hand you the passed paperwork. Depending on where you live that is the City of Brighton, Adams County, Weld County, or your local jurisdiction.
Natural gas or propane?
Either. Most metro homes run natural gas. Acreage and rural properties around Fort Lupton and Hudson often run propane, and we size the fuel supply so the generator can run for days, not hours.
How long does installation take?One to two days on site for most homes once the unit is available, plus the inspection. Lead times on popular sizes vary, so ordering before storm season beats ordering during the first big outage.
What size generator do I need?Most homes land between 18kW and 26kW for whole home coverage. The honest answer comes from the load calculation we run before quoting, so you do not pay for capacity you will never use.
