There are four generators which develop a power of 380 MVA each (power factor 0.85) and are of the windings direct cooling type.

The stator winding is cooled by the circulation of deionised water which passes through the hollow conductor which forms part of the semi-coils. The rotor winding is cooled directly by hydrogen.

The generated power is despatched to WAPDA's grid through two overhead 500 kV lines through a half-breaker scheme, SF insulated substation. There are also two start-up transformers. Station power supply and unit auxiliary power supply are provided to minimise any effects of equipment failure or maintenance on continuity of service.

The electrical auxiliary power system rests on three major sub-systems:

• AC power system
• DC power system
• AC emergency power system

The station transformers performs the start-up and shut-down of the plant and supplies the common services boards.

The emergency ac source is ensured by emergency diesel and 110V inverters, supplying the loads necessary for the safe shut-down of the power plant.
