Sitara Energy Ltd is one of the most modern and largest captive plants in Pakistan. Electrical energy is produced by twenty-four generator sets. Eight generator sets operate on diesel fuel and sixteen operate on natural gas. The maximum output power is 80 MW. The power plant is equipped with a combination of the most modern technology from Japan, Europe and USA. 30 MW of electrical energy is supplied to Sitara Group of Industries' subsidiaries and 20 MW is supplied to Faisalabad Electric Supply Company (FESCO).
A general reconstruction of the twenty-four generator sets was carried out from 2005 to 2007. The reconstruction included a modification of the generator sets. Their fuel systems were modified to operate on diesel fuel and natural gas. The whole contract was carried out by Motor System s.r.o. The Reliance SCADA/HMI system was installed for the control and visualization of the generator sets and also for the control of other engineering facilities. The Reliance system provides communication with WOODWARD Control System over the Modbus protocol. All important parameters from operation are controlled by Reliance. Data from the operation is automatically stored in a database. The historical data is used for displaying historical trends, alarms/events, and other relevant information. The operator (Sitara Energy Ltd) is very satisfied with the control system installed in its power plant.
