All stages of high voltage substation design and development, and power transmission at different voltage levels (63kV, 132kV, 230kV and 400 kV) are performed in this unit. The engineering design of high voltage substations is done based on valid international standards and the technical specifications of the most prestigious consultants in the electrical industry, as well as other industries such as oil, gas, petrochemical, steel and cement.

This unit consists of four major professional groups:

1. High Voltage (HV)

2. Low Voltage (LV)

3. Civil Department (CIVIL)

4. Automation and Digital Control System (DCS)
