A power system has the following generating units available (this is available rated electrical output): 1200 MW nuclear (33% efficiency) 1200 MW coal (Subbituminous coal in pulverized fuel steam plant; 33% efficiency) 600 MW natural gas (Combined-cycle gas turbine (CCGT) plant; 55% efficiency) 80 MW natural gas, (Open-cycle gas turbine (OCGT) plant; 35% efficiency) 600 MW wind (During the hour, the installed wind capacity is generating 600 MW) 100 MW solar photovoltaic (100 MW being generated during the hour) The system is operating at constant 3600 MW load and generation for one hour. CO2 emission by fuel (lb of CO2 emitted per mmBtu of fuel burned) Coal EF Oil EF Gas EF Bituminous 205 Distillate oil 161 Natural gas 117 Subbituminous 213 Jet fuel 156 Propane 139 Lignite 215 Kerosene 159 Anthracite 227 Petroleum coke 225 Residual 174 The cost of fuel for the three types of generators are: Nuclear fuel: 0.44 $/mmBtu mmBtu is 10 Btu Coal: $1.50/mmBtu Gas: $3.40/mmBtu This is the cost of fuel going into the plant, so you must use the efficiency of the plant to calculate cost of electricity out. 1. Calculate: a. The generation used and the total fuel cost for the hour at the lowest possible fuel cost. Also calculate the total CO2 emissions for this case. b. The generation used and the total fuel cost for the hour at the lowest possible CO2 emissions. Also calculate the total CO2 emissions for this case.
