Question 5. 15 Points The fuel-cost functions in $/h for two thermal generation stations are given by C1 = 800 + 6.0P1 + 0.004 P12 C2 = 1000 + 6.8P2 + 0.002 P22 where P1 and P2 are in MW. The total power demand is 1300 MW. Neglecting losses, determine the optimal generation of each plant and the incremental cost of power λ ($/MWh).
