The economic analysis is conducted using the Levelized Energy Costing (LEnC) method, based on the net energy output from the IMWtE by the CHP system. The key parameters include the investment cost (Inv), operation and maintenance costs (OM), discount rate (r), annual operating time (tOT), real interest rate (iReal), inflation rate (iInflation), and deterioration factor (DF). The procedural steps for determining the economic outcomes are presented in Topics 3E and 1L model , The economics analysis present as Table.
