Underground substations

Bustling urban centers need efficient and reliable electricity, but usually do not have space for large electrical installations.

Placing the substation underground reduces space requirements at downtown sites, since the free surface area can be used for other purposes, such as shopping malls or parks. The purpose of underground substations is to provide all the functionality of a conventional substation while minimizing the area occupied above ground.

Hitachi ABB Power Grids underground substation concept enables up to 98 percent of the installation’s volume to be hidden and includes state-of-the art technologies to minimize noise emissions. These innovative and proven solutions enable the most stringent requirements for power supply within urban areas to be fully met - compactness, economy, reliability and safety, while allowing for easy maintenance access and future expansions.
