Net Heat Rate (LHV of fuel) at loads :100% 75% 50%

At Ambient Air Temp.350 C, KJ/Kwh -------- -------- --------

i) Net Power Output

Net power output shall mean the power output produced by Gas Turbine Generator and Steam Turbine Generator in Combined Cycle mode measured at the high voltage side of step up transformers. ii) Net Heat Rate Net heat rate shall mean the heat equivalent of the fuel consumed by complete Combined Cycle Plant per unit time, based upon the Lower Calorific Value, divided by the net power output as defined above. iii) Cooling Water Temperature Cooling water Temperature from cooling tower at inlet of Steam Turbine Condenser and auxiliary cooling water Coolers is to be of 380C at site condition (350C, 1.013 bar, 98% R.H). However, the net output of complete Combined Cycle Power Plant and Steam Turbine Generator shall not be less than the guaranteed figure at site condition. iv) The guarantee performance data are to be based on the proposed Heat Balance Diagram (will be submitted during detailed design stage) and Correction Curves and/or Tables (will be submitted during detailed design stage), which are to be submitted with this Contract and which are only to adjust the guarantee performance data, should the operating conditions during the performance tests differ from the above guarantee data. v) Starting and Loading Time The Steam Turbine Generator starting time to reach Full speed no load (3000 rpm) counting from Gas Turbine start-up command to be as follows (to be guaranteed): - Cold Start (from ambient Conditions) : --------hr ------- min ( max 4 hours)

- Warm Start (after 8 hrs shut down period): ------hr ------ min ( max 2 hours)

The Steam Turbine Generator loading time up to MCR counting from Synchronisation -------- min, to be guaranteed.
