Shipping Container Generator Enclosures

A shipping container fabricated to house and protect a generator — weatherproof, ventilated and lockable, built to order around the unit going inside it. There is no list price, because there is no standard build. Tell us the generator and the site and we'll quote it.

The concept

What a container generator enclosure is

A container generator enclosure is a shipping container fabricated to house and protect a generator. Instead of leaving the unit sitting out in the open on a pad, the generator lives inside a corten steel container that our crew has modified for the job — weatherproof, ventilated and lockable.

The appeal is simple. A shipping container is already a sealed steel box designed to survive years of weather and rough handling, and it is already built to be picked up and set down by truck. Turning one into a generator building means the protection and the security come from the shell itself rather than from a structure that has to be built on site.

Cactus Containers builds these to order. There is no catalog version, no standard drawing and no list price — which is why this page asks you to call instead of showing a number.

Weatherproof

The enclosure is a sealed steel shell. Sun, rain, wind-blown dust and Texas weather stay on the outside of it.

Ventilated

A generator inside a steel box has to breathe. Ventilation is part of the fabrication and is worked out for the unit going in.

Lockable

Container doors and hardware lock. On a remote or unmanned site that is often the reason the enclosure gets built in the first place.

Custom fabrication

Cutting, framing, doors, access panels and finish are done by the Cactus Containers crew — not ordered in and bolted on.

Built to order

Every enclosure starts as a conversation about a specific generator on a specific site. Nothing is pulled off a shelf.

Delivered from a Texas yard

Finished enclosures go out on a tilt-bed truck from whichever of the three yards sits closest to your site.

Say it plainly

This is a modification, not an accessory kit

Two very different things get confused on container websites, so here is the difference in our own words. A generator enclosure is firmly on the left.

This page

Modification

Fabrication work our own crew performs on a container. A generator enclosure is a modification. So are office conversions.

  • We supply the container and do the work
  • Scoped and quoted per project
  • You take delivery of a finished enclosure
  • Never assembled "from a kit"
Different product

Accessory kit

A product we sell to a customer who is modifying their own container. Cactus does not install accessory kits.

  • You already own the container
  • You buy the kit and fit it yourself
  • Sold as a listed item, not a build
  • See the accessory kits
Why there's no price

Built around your generator, so it's quoted per build

The enclosure is fabricated to suit the unit that goes inside it. Change the generator or change the site and you change the build — which is why a single published price would be a fiction.

No list price · quoted individually

Tell us the generator and tell us the site, and we'll quote it. You do not need drawings or a spec sheet to start the conversation — the make and model of the unit, roughly how big it is, and where it has to live are enough for us to work from on a first call.

From there our crew scopes the shell size, the ventilation, the doors and access, and the security and finish, and comes back to you with a price for the whole build. Quoted prices are plus tax if applicable.

The generator itselfWhat the unit is and how much room it needs decides the shell and the layout of the enclosure around it.
VentilationA generator inside a sealed steel box has to breathe. How the enclosure is ventilated is worked out for your unit.
Access and doorsHow you need to get to the unit to service it — where the openings go, how big they are and how they close.
Security and finishLocking arrangement, paint and any branding. On unmanned sites, lockable is usually the whole point.
The siteWhere it is going, what the ground is like, and whether a tilt-bed truck can back in and set it down where you want it.
Delivery distanceHow far the finished enclosure has to travel from the Decatur, Amarillo or Midland yard to reach you.
Who asks for these

Where a container generator building makes sense

Anywhere a generator has to sit outdoors, unattended, and keep working. If your situation isn't on this list, it is still worth a call.

Oilfield & Permian Basin sites

Remote pads and lease roads across the Permian, Odessa and the West Texas oilfield, where the nearest person may be a long drive away. Our Midland yard is the closest one to most of them.

Ranches & rural property

Pumps, wells and outbuildings a long way from the meter. A steel enclosure keeps the unit out of the weather and locked up between visits.

Job sites & contractors

Site power that has to be secured overnight and moved to the next job afterwards. The enclosure travels the same way the container did.

Backup power at facilities

Standby units at plants, shops, warehouses and yards, where the generator needs to be protected and secured without giving up floor space inside the building.

Telecom & remote sites

Tower sites and unmanned installations where the equipment has to keep running and nobody is on site to keep an eye on it.

Anywhere in Texas

Decatur covers DFW and North Texas, Amarillo covers the Panhandle, Midland covers the Permian Basin and West Texas. Call whichever yard is closest.

The shell

Base container options

Every enclosure starts as a standard ISO shipping container. These are the exterior dimensions of the shells we build on — useful when you are working out whether your unit will fit and where the enclosure can sit.

Standard ISO exterior dimensions. Usable interior space is slightly smaller than the exterior figures, and the finished enclosure's interior depends on the fabrication. Which shell suits your generator is part of the quote — call (432) 423-2507.
Base container Exterior dimensions (L × W × H) Where it tends to fit
20 ft standard 20' L × 8' W × 8'6" H The compact shell. Smallest footprint on the pad and the easiest to place on a tight site.
20 ft high cube 20' L × 8' W × 9'6" H Same footprint as a 20 ft standard with a foot more height, when headroom is the constraint rather than length.
40 ft standard 40' L × 8' W × 8'6" H Twice the length. Room for a larger unit, or for the unit plus working space around it.
40 ft high cube 40' L × 8' W × 9'6" H The largest of the four — full 40 ft length with the extra foot of height.

How it works

How a generator enclosure build goes

Four steps, and the first one is a phone call or the quote form below.

STEP 01

Tell us the generator

What the unit is, roughly how big it is, and where it has to live. Rough details are fine — you don't need a spec sheet to start.

STEP 02

We scope the build

Shell size, ventilation, access and doors, security and finish. Our crew works out what the enclosure actually has to be.

STEP 03

You get one quoted price

Container, fabrication and delivery land in a single number for the build — plus tax if applicable. No list price, no guessing.

STEP 04

We build it and deliver

The crew fabricates the enclosure and a tilt-bed truck sets it on your site. Level, firm ground and room to back in and tilt are what we need.

Request a quote

Send us the details and we'll price the build

Prefer to write it down rather than talk it through? Fill in the form and tell us what the generator is and where it's going. Someone from the nearest yard picks it up from there.

The generator — make, model or roughly how big
The site — city, county or ZIP is plenty
How you need to get to the unit to service it
Anything else the build has to allow for

No obligation, and no price is published for this build — the quote comes back to you directly. Quoted prices are plus tax if applicable. Rather talk? Call Midland (432) 423-2507.

Common questions

Generator enclosure FAQs

The things people ask us first about container generator buildings.

Can you build a generator enclosure from a shipping container?
Yes. Cactus Containers fabricates shipping containers into generator enclosures — a steel container built to house and protect a generator, weatherproof, ventilated and lockable. The work is done in-house by our own crew, and each enclosure is built to order around the unit going inside it. Call Midland (432) 423-2507, Amarillo (806) 557-3508 or Decatur (940) 291-2797 to start one.
How much does a container generator enclosure cost?
There is no list price for a generator enclosure, and that's why no number appears anywhere on this page. Every enclosure is fabricated around a specific generator on a specific site, so the build is quoted individually. Tell us what the generator is and where it's going and we'll price the build for you — send the details or call the yard nearest the site. Quoted prices are plus tax if applicable.
Do you deliver generator enclosures in West Texas and the Permian Basin?
Yes. Our Midland yard on E County Rd 73 covers the Permian Basin, Odessa, Big Spring, Andrews, Stanton and the West Texas oilfield, and it's the closest yard for most Permian sites. The Amarillo yard covers the Texas Panhandle and the Decatur yard covers DFW and North Texas. Enclosures are delivered by tilt-bed truck, so the placement spot needs reasonably level, firm ground and room for the truck to back in and tilt.
Is a container generator enclosure an accessory kit I install myself?
No. A generator enclosure is a modification — fabrication work performed by our crew on a container we supply. It is not an accessory kit. Accessory kits are separate products sold to customers who are modifying their own container and doing the installation themselves. A generator enclosure is not built from a kit and is not installed by the customer.
What size shipping container is used for a generator enclosure?
The shell is a standard ISO shipping container. We build on 20 ft and 40 ft containers in both standard height and high cube. A 20 ft standard is 20' × 8' × 8'6", and a 20 ft high cube is the same footprint at 9'6" high. A 40 ft standard is 40' × 8' × 8'6", and a 40 ft high cube is 40' × 8' × 9'6". Which shell suits your unit is part of the quote conversation — see the base container options above, then call the yard and describe the generator.
