What is..?
An E House, also known as an electrical house or e-house substation, is a prefabricated, modular enclosure that integrates electrical equipment into a single, factory built unit. E Houses are designed to house medium and low voltage switchgear, transformers, protection and control systems, SCADA, UPS, batteries and auxiliary systems within a controlled environment.
Manufactured in factory controlled conditions, E Houses are fully assembled, wired, tested and commissioned before shipment. Once delivered to site, they are installed and connected to external power sources and loads, enabling rapid energization. This approach replaces traditional on site electrical rooms with an industrialized, plug and play solution that meets international electrical and safety standards.

Advantages
E Houses significantly reduce project schedules by shifting complex electrical integration work from site to factory. Parallel manufacturing and site preparation shorten time to power and reduce commissioning risks.
Factory integration ensures high quality workmanship, consistent standards and extensive pre testing, minimizing on site errors and rework. Controlled environments improve safety during assembly and enhance long term reliability of sensitive electrical equipment.
Modular design enables scalability and flexibility. E Houses can be customized for project specific electrical requirements and expanded with additional modules as capacity grows.
Cost predictability is improved through standardized engineering and reduced site labor, while logistics and installation are simplified, especially in remote or harsh environments.

Usage Areas
E Houses are widely used in oil and gas facilities, mining operations, power generation plants, renewable energy projects, substations, industrial plants, data centers and large infrastructure developments.
They are especially valuable in remote locations, offshore and onshore energy projects, deserts, cold climates and fast track developments where traditional construction is slow or risky.
E Houses also support temporary or relocatable power installations, grid reinforcement projects and mission critical electrical infrastructure requiring high reliability and rapid deployment.
