A pоwer system hаs three generаtоrs: Generаtоr A has a heat rate of 9 mmBTU per MWh and a capacity of 10 MW; Generator B has a heat rate of 7 mmBTU per MWh and a capacity of 15 MW; Generator C has a heat rate of 10 mmBTU per mWh and a capacity of 20 MW. The fuel price for all power plants is $5 per mmBTU and all the generators have zero fixed costs. If demand for electricity is 35 MW, what is the system lambda?
