To apply the CCP expression, the cost of the total fuel input and the value of the fuel credit must be calculated separately as follows:

Total fuel input cost _ 12.029 cf/kWh x \$3.50/Mcf x 1 Mcf/1,000 cf_ \$0.042/kWh

Fuel credit value _ 7.628 cf/kWh x \$2.70/Mcf x 1 Mcf/1,000 cf_ \$0.021/kWh

The CCP, based on Equation 2-22, is:

\$fuel cost — \$fuel credit + \$O &M cost _ \$Operating cost \$0.042/kWh — \$0.021/kWh + \$0.008/kWh _ \$0.029/kWh

Fuel input (HHVbasis) _ 11,300 Btu/kWh x 1.11 _ 12,553 Btu/kWh

The heat rate of the combined-cycle system, based on Equation 2-11, is: 12,553 Btu

1.175 kWh

= 10,683 Btu/kWh (HHVBasis)

The fuel rate, on an HHV basis, based on Equation 2-12, is:

10,683 Btu/kWh

1,020 Btu/cf

The energy credit for recovered heat, on an HHV basis, based on Equation 2-18, is:

4,540 Btu/kWhTotd 0.83

= 5,470 Btu/kWhTotal and the fuel credit is:

5,470 Btu/kWh

1,020 Btu/cf

The ECP, on an HHV basis, based on Equation 2-20, is:
