E-House solutions – the fast-track project approach

E-Houses are customized, pre-assembled, and pre-tested modular power substations. They are ideally suited for use in situations where fast deployment and reduced on-site work are needed, or in locations that are difficult to access. The simple reason is that they are easy to assemble and put into operation. They provide a rapid and flexible power supply, precisely where it’s needed. E-Houses have proven themselves as an alternative to conventional power distribution solutions. They have been installed in large numbers throughout the world in industry and infrastructure, and for network operators.
