8. a wood chip fueled rankine cycle 54-mw electric power generation plant uses chipped pine bark beatle deadfall as fuel. the overall efficiency of the power plant is 27% and the capacity factor of 80%. the as-received wood fuel is 45% carbon, has a higher heating value of 16.0 mj/kg, and the wood is not harvested sustainably. carbon emissions are taxed at the rate of $25/mgco2e. the life of the system is 25 years and the interest rate is 5.5%. assume an operations and maintenance cost of $0.025/kwh. the initial cost of the system is $4000/kw. the cost of wood chips is $6 per mbtu. a. what is the heat rate of the power plant (btu/kwh)? b. what is the cost of fuel per kwh of electricity generated ($/kwh)? c. how much electrical energy is generated annually by the power plant (mwh/y)?
