The input-output curve of a gas-fired generating unit is approximated by the following function: 4.2 H(P) = 120 +9.3 P + 0.0025 P² MJ/h This unit has a minimum stable generation of 200 MW and a maximum output of 500 MW. The cost of gas is 1.20 $/MJ. Over a 6-h period, the output of this unit is sold in a market for electrical energy at the prices shown in the table below. 2 3 Period 1 4 6. Price ($/MWh) 12.5 10 13 13.5 15 11 Assuming that this unit is optimally dispatched, is initially on-line and cannot be shut down, calculate its operational profit or loss for this period.
