Unit Cash Cost (UCC) for Cogeneration Plant

Unit Cash Cost (UCC) for Cogeneration Plant

Unit Cash Cost (UCC) for Cogeneration Plant

(OP)
Hi,

I was requested to calculate the UCC for our newly installed Cogen Plant (4 GTGs + 1 STG) and to compare with the charges by the utility power company. Below is the sample of calculation.

Post Cogen : RM 68.2/MW-hr or USD 20.1/MW-hr
Utility Company : RM 220.5/MW-hr or USD 64.9/MW-hr

Appreciate if anyone could provide some comments on the accuracy of the calculation.


    UNIT CASH COST (UCC) : POST COGEN OPERATION                            
1.Electricity : 68.5MW                    
        600,060    MW-hr/Year                    
2.HP Steam (from HRSG only):247.6 ton/hr                    
  2.17 Million ton/Year                    
  1,941,581 MW-hr/Year    
                
3. Combined MW-hr/Year : 2,541,641 MW-hr/Year                    

4. Total OPEX :    114.8 RM Million/Year (OPEX to generate 68.5 MW and 247.6 ton/hr of HP Steam)                    
5. CAPEX Recovery : 58.7 RM Million/Year (based on Total CAPEX = RM 578 million, 20 years period, 8% interest)                    
6. Total Cost :173.5 RM Million/Year                    

7. Combined Power UCC : 68.2 RM/MW-hr (average power utility company charge is RM 220.50/MW-hr)

8. Exchange rate : RM 3.4 = USD 1.0

Thanks

ppm
