Modular E-houses for power and control

KeyPlants delivers advanced modular E-Houses designed to meet the growing demands of modern power infrastructure. These prefabricated electrical houses are engineered for rapid deployment, high reliability, and long-term scalability — making them ideal for both temporary and permanent installations across industrial, energy, and utility sectors. Each E-House is built offsite under controlled conditions, equipped with all necessary components, and delivered fully tested for immediate connection and commissioning.

The fast, scalable way to add power capacity

KeyPlants’ modular E-House solutions for low, medium, and high voltage networks offer maximum quality, with the flexibility to expand capacity as needed. These prefabricated E-Houses are a simple and efficient way to add new power infrastructure or replace aging systems — without the delays and complexity of conventional on-site construction.

If an E-House system fails, it’s never without cause. That’s why KeyPlants prioritizes quality and precision throughout the manufacturing process. All E-Houses are fabricated in our controlled indoor facility in Emtunga, ensuring every structure is protected from weather conditions during assembly, equipment installation, and testing.

Installed, tested, and ready to go

Each modular E-House is delivered fully equipped with transformers, switchgear, ventilation and cooling systems, backup, and battery power. All components are installed and rigorously tested before delivery, saving significant time and cost on-site. This turnkey approach ensures reliable commissioning and shortens the path to operational readiness.

A key advantage of our prefabricated E-Houses is the ability to carry out site preparation in parallel with offsite construction. This overlap significantly reduces project timelines compared to traditional construction. The solution is also inherently scalable — modules can be added over time or relocated entirely if needed.

The E-Houses are also stackable, making them ideal for locations with limited space or where future capacity growth is expected.

Why choose KeyPlants for power modules?

Scalable & Future-Ready

Install to meet your current needs and add capacity later as demand grows. Our modular E-Houses are built for seamless expansion.

Controlled Indoor Build

All power modules are fabricated in KeyPlants’ indoor facilities, ensuring protection, precision, and consistent quality throughout.

Fast Delivery Timelines

Our modular E-Houses are ready in just a few weeks, drastically reducing lead times compared to traditional construction.

Fully Equipped & Turnkey

Each unit is delivered with transformers, switchgear, ventilation, cooling systems, backup, and battery power — all pre-installed and tested.

FAT-Tested Systems

All systems undergo comprehensive FAT before delivery, ensuring performance, safety, and compliance from day one.

Relocatable Modules

Need to move your E-House? Our modular units are built for relocation, providing flexibility in dynamic operating environments.

Protected manufacturing indoors and shorter delivery times

All manufacturing is undertaken indoors, so the facility is protected throughout the fabrication and installation, ensuring quality.

The modular facilities are safely and securely completed in a controlled environment at KeyPlants’ workshop in Emtunga. All equipment is installed prior to delivery, which saves considerable time and costs on site, and enables guaranteed delivery to end customers and commissioning.

A major advantage of prefabrication is that the on-site groundwork and infrastructure can be completed while the facility is being manufactured. This reduces the time to complete the building significantly, compared with on-site construction of a similar structure.

The dimensions of the modules we build are designed according to the client’s specifications, but are usually 13,350 (l) x 4,450x (w) x 4,100 (h). These particular dimensions were developed as a result of over 25 years of transportation and installation experience, and it has proven to be the safest, most secure and cost-effective size for a module. Moreover, for larger buildings they form perfect modular symmetry, as with Tetris.

FAQ

What is a modular power module?

A power module is a prefabricated electrical unit that includes everything needed for power distribution — such as transformers, switchgear, ventilation, and control systems. It’s built offsite and delivered as a turnkey solution for fast deployment.

How is an E-House different from a traditional electrical building?

Unlike traditional site-built structures, E-Houses are manufactured in controlled indoor environments. This reduces weather delays, ensures higher build quality, and enables faster installation and commissioning.

What components are typically included in a power module?

KeyPlants’ power modules come fully equipped with transformers, medium- and low-voltage switchgear, HVAC systems, and backup power — all pre-installed and tested before delivery.

How long does it take to deliver and install a modular E-House?

Thanks to parallel site prep and offsite fabrication, delivery can often happen within weeks. Modules arrive fully equipped, allowing for quick installation and reduced on-site work.

Can power modules be relocated or expanded later?

Yes. Our modular systems are designed to be both scalable and relocatable, making it easy to adapt to future power demands or site changes without major reconstruction.
