Siddhirganj 2x120 mw peaking power plant

Siddhirganj 2x120 mw peaking power plant. Two units 120 mega watt each (electric power, not thermal). Gas turbines running on open loop Brayton cycle. Thermal efficiency is pretty low (refer to the inside contents). One interesting thing is that an Indian company called BHEL (Bharat Heavy Electricals) manufactured/established this plant here in Bangladesh (some equipment from GE, I'd be remiss if I didn't at least mention). One last thing to notice is the term "peaking". It means the plant provides power to the grid during peak hour (6-11 pm).
