Industrial mining projects use pre-manufactured Electrical Power Houses (Ehouses) for completing projects on schedule and within budget. I am often asked what makes these Ehouse units a better choice than a permanent electrical room, and when an Ehouse should be considered for projects. Before I answer these questions, let me first define an Ehouse.

Ready to ‘Plug and Play’

An Ehouse is a self-supported pre-engineered building that contains and houses most of the electrical equipment for an industrial project. Ehouses come in a variety of shapes and sizes to meet the project requirements and can contain anything from a single medium voltage Variable Frequency Drive (VFD), to a low-voltage motor control center (MCC) and control panel, or even the entire electrical and control distribution systems for an industrial process like a barren solution pump station. They come pre-connected and are essentially ready to “plug and play” into the field devices/equipment. Ehouses are also capable of being relocated or, once the life of the process is done, they can be decommissioned or repurposed much easier than a permanent building.

The interior electrical components are pre-wired and tested by the Ehouse manufacturer prior to shipment. The remainder of the work, once the Ehouse is delivered to the site, is to place it in its intended location and connect the external electrical connections for power, controls, and grounding.
