Electrical Substation Design

We invest our specialized knowledge and experience in building enduring relationships with clients for the good of our communities.

TOTH’s team of professional engineers and supporting staff provides customized consultation, design and support from initial project conceptualization through station commissioning. Clients include an array of municipalities, industrial and rural electric cooperatives. Station design services include new construction, expansions and upgrades for medium voltage stations through EHV class stations. TOTH’s engineers are well-versed in relaying protection, design protection and control, and testing of substations.

Our station design team uses cutting edge 3D modeling and rendering, which allows for clear communication and better collaboration with our clients. A virtual station “fly-through” allows clients to see the station before it is ever built.
