Economic Analysis of Applications

The figures given in the first column of the table can be calculated as follows. From the production rate of methane 

The costs to generate the electricity by internal combustion engine are summarized in Table 10.7. The levelized capital costs (0/kWh) in column 2 can be calculated as follows. 

Further, adding operation and maintenance (O M) expenses (1.80 0/kWh), the resulting cost of electricity generated becomes 3.30 0/kWh. 

As a conclusion the projects are not feasible unless the price of such gas is greater than 4.89 and 4.58 /nimBTU at the interest rate of 8 and 5%, respectively, for the 1 million t landfill. Te price should be higher than 2.15 and 2.01 /mmBTU, respectively, at the interest rate of 8 and 5% for the 5 million t landfill.
