Standby Generator Installation for Existing Buildings Across DFW

Most of the generators we install go on buildings that are already open and running, not under construction. (Building new? See our new construction page.) We plan the install around your lot, landscaping and day-to-day operations, for businesses across Fort Worth, Dallas, Southlake, and the rest of North Texas.

The difference

Built Around Your Building, Not a Blank Lot

On new construction, conduit and gas line get run while the walls are still open and no landscaping exists yet. On a building that's already finished, there's no open wall to route anything through, so every foot of conduit and gas line has to work around a parking lot, a loading dock, or whatever's already in the ground.

That's why the site visit comes first: a free, no-obligation look at your electrical panel, your gas supply and meter, and where a generator and pad can realistically go, including what your HOA or landlord will allow. If a smaller system covers your load, we say so; any installer who quotes a number before seeing your property is guessing.

The site survey

What the Site Survey Actually Covers

A specific, well-defined look at your building, not a drive-by estimate.

Electrical Panel Assessment

We check your panel's capacity and layout to confirm it can support a transfer switch, and flag any upgrades the panel itself would need before a generator goes in.

Gas Supply and Meter Check

We confirm what gas supply and meter capacity you actually have on site before sizing anything, so the generator we recommend matches what your utility connection can deliver.

Pad Siting Against the Clearances

We plan the pad location against the clearances for windows, doors, fresh-air intakes and service access, matched to what's already built on your site rather than a blank-lot assumption.

Permitting Path

We scope the permitting path for your specific city before anything is quoted, since requirements and turnaround vary by jurisdiction across the metroplex.

What this means for your business

A Single, Accountable Point of Contact

  • One company accountable from the first call to the final walkthrough.
  • One point of contact for the whole project, start to finish.
  • A single written quote that lists everything included at one total price, not itemized line by line.
  • Written approval required before any work outside the original scope begins.

Permits and inspections

We Handle the Permits, You Run Your Business

Permitting requirements and turnaround vary considerably across the metroplex, which is why an existing-building install is scoped against your specific city rather than a generic timeline.

We Pull the Permit

Texxas Power pulls the permit and schedules the inspection for your install, so you don't have to deal with the city yourself.

What Sets the Pace

Permitting is usually the step most likely to take longer than the rest of the job, and it varies by city. We don't promise a fixed number of days anywhere: the permit office, your utility's schedule, weather, and equipment delivery set the pace. Installation itself typically runs three to five weeks once equipment arrives.

How it runs

How an Existing-Building Install Runs

01

Sales Visit

A free, no-obligation visit to look at your panel, your gas supply, and the realistic pad locations on your site, so we size the system honestly instead of guessing.

02

Internal Review

Our team reviews what the site visit found before anything is filed with the city, so the permit application matches what's actually on your property.

03

Permitting

We pull the permit and schedule the inspection. Timing varies by city, your utility's schedule, weather, and equipment delivery, not a fixed number of days.

04

Install

Pad, gas line, electrical and transfer switch go in. A dig test runs before any trenching starts, so what's already buried is known before anything is cut, and anything outside the original quote gets your written approval before work starts on it.

05

Startup

The generator is registered under the manufacturer's warranty and started up.

06

Generator School & Simulation

We show you how to run the system and what to watch for, then cut power on purpose and confirm it carries your load while you're standing there.

Common questions

Frequently Asked Questions

(817) 439-9009
Does installing on an existing building need different permits than new construction?

Yes. Texxas Power pulls the permit for an existing-building install, and the process is scoped to your specific city rather than treated as a standard timeline, because requirements vary by jurisdiction across the metroplex.

How long does an install take once you start?

Once equipment arrives on site, installation typically runs three to five weeks. Before that, the permit office, your utility's schedule, weather, and equipment delivery are what set the overall pace, which is why we don't promise a fixed number of days.

Will this disrupt our business?

Our plan is built around your building staying open, not shutting down for us. The site visit looks at how to route conduit, gas line and pad placement around your existing lot and day-to-day operations, and anything outside the original quote needs your written approval before we touch it.

Can you work around our parking lot and landscaping?

Yes. That's what the site visit is for: looking at where a generator and pad can realistically go given what already exists, a paved lot, landscaping, a loading dock, or whatever's in the ground, and running a dig test before any trenching so we know what's buried first.

What if there's no obvious spot for the pad?

That's exactly what the site visit determines. We assess your panel, gas supply and meter, and the realistic pad locations against the required clearances, including what your HOA or landlord will allow, before anything is quoted.

Do you handle the permit?

Yes. Texxas Power pulls the permit and schedules the inspection, so you don't have to deal with the city directly.
