Plant B of the Sapugaskanda Thermal Power Stations has eight 10MW installed capacity-diesel generators and has an annual energy production of 500GWh. This plant with approximately 260 employees was commissioned in two phases in September 1997 and September 1999 respectively (B1 & B2) with the Instrumentation and Control system of Siemens Simatic S5. This system was first implemented thirty years ago functioning as a Data Acquisition system. However, the migration to Simatic S7 has become essential for all automation systems, especially for increased functionality, availability and efficiency.
Thus, Siemens together with DIMO took on the challenge of upgrading the Sapugaskanda Plant with minimum disturbance to the operations of the plant and successfully completed the project without any loss of production and zero hazards.
