The electrical engineering division of EGB has grown from small beginnings and today there is a dedicated vertical for E BOP, Switchyard, Transmission & Distribution with highly specialised work force dedicated towards executing projects with state of the art technology.

We have the capacity to design, supply, erect, test & commission 400kV, 220kV, 132/110kV, 66kV, 33kV, 11kV substations / switchyards with transmission lines.

For any project, design and engineering of the entire project is completed taking all parameters into consideration to ensure smooth system integration. After this, procurement, supply and installation is carried out in a sequential manner. Testing and commissioning of switchyards are performed as per applicable standards.
