این نیروگاه  دارای مشخصات زیر است : 

2 x 6B Gas Turbine
Turbines Description
Essentially, the plant consisted of two x 42MW natural gas fired GE F6B
gas turbine generators each matched up to a Zurn 112 tonne per hour
natural circulation HRSG’s with supplementary gas duct firing contributing
approximately 50 tonnes per hour of that per unit total and a nominal
43MW GE controlled extraction condensing steam turbine generator
providing up to 2800 tonnes per day of process steam at 1320 kPa and
270°C. Beyond that are the related ancillaries – water demineralizing
plant, steam turbine bypass conditioning system and cooling tower.
The specifics of the turbines are as follows:
1. GAS TURBINE 1A
Serial No.:
GT1A - A GE field converted PG6581 gas turbine and 11.5kV generator
with approximately 210k fired hours and 200 fired starts worth of
operation over the 25 year operational history while noting that the
installed turbine rotor has experienced only 175k fired hours and 150
fired starts.
