Siemens Energy Acquires the eHouse Manufacturing Business

Siemens Energy Inc. is expanding its business portfolio by acquiring the eHouse manufacturing division of Integrated Electrical Services Inc. (IES), a national electrical and communications service provider based in Houston. Formerly known as Tesla Power & Automation, this newly acquired business provides custom packaging of electrical equipment and drive systems into custom-manufactured enclosures called eHouses.

“This is a great addition to our product and solution portfolio. This acquisition will allow us to strengthen our market position and competitiveness and is consistent with our ongoing strategy to provide our customers with competitive packaged power solutions,” said Doug Keith, Siemens Energy vice president and general manager for Medium Voltage North America.

Also known as power equipment centers or power distribution centers, eHouses are metal fabricated buildings that typically house medium- and low-voltage electrical switchgear with transformers, battery systems, etc. Upon completion, the eHouses are transported to the customer site.

“Using eHouses makes for a simple and quick installation when compared with permanent brick-type buildings,” said Douglas Proudfoot, Siemens Energy business segment manager for MV Package Power Solutions. “All the electrical equipment is installed in the eHouse at the factory and fully tested prior to shipment. At the site, the eHouse is lifted from the truck, placed on the foundation and the electrical connections are made.”

The newly acquired business is located in Houston. Siemens Energy also has a significant presence in the area with more than 1,500 Houston-based employees. The facility will remain open and will become part of the Siemens Energy Power Distribution Division.
