Authors Abstract (if any)
Cost estimates for subcritical, supercritical and ultrasupercritical pulverized coal (PC) plants are presented for representative US bituminous coals and compared with IGCC technologies. The basis of the designs are discussed, including the difference between the US and European definitions of efficiency and calculation methods. The build up of the various components of the Total Capital Requirement (TCR) are shown and the effects of different assumptions regarding the additional Owners costs (OC) on the Cost of Electricity (COE) for each technology are addressed. The results show that the Total Plant Cost (TPC) for IGCC is slightly higher than PC when designed for 90% equivalent availability and at the current state of development IGCC probably requires more staff than PC. There are also additional cost elements and higher perceived risk factors for IGCC that can affect the project development schedule and financing charges and increase the Owners Costs to a greater extent than for PC. If IGCC is to become a real option for coal-based Power Generation some additional incentives may be required.
