Projects


Mitsubishi Electric Substation Division (SSD) provides professional services that have been refined and developed over years of working on multi-million-dollar capital projects for power utilities and commercial & industrial clients. The testament to all that SSD’s team accomplishes is embodied in the projects completed across North and Central America.

The SSD projects are almost exclusively full solutions and their derivative systems that are designed and customized for each instance. Rarely is a simple product supplied, as our goal is to always be an exacting and complete engineering services provider that meets our customers where they need us:

Each project provides not only the personnel associated with these functionalities, but the years of developed knowledge, process, practices, methods and intellectual property associated with SSD and Meppi.
