Preliminary capital cost estimates of new 1000 MW power plants (2 to 500 MW units) designed specifically to fire solid solvent-refined coal (SRC-I have been prepared. The cost estimates were developed for plants designed to meet several different emission requirements including the Federal New Source Performance Standards (NSPS) and the New Mexico standards that were in existence in 1976. A sensitivity of the capital costs to even more stringent standards was also included. Separate cases were developed for plants firing SRC-I from eastern coal (midwest power plant location) and SRC-I from western coal (western power plant location). Capital cost estimates for 1000 MW coal-fired plants (2 to 500 MW units) in the same locations were developed for reference purposes. The principal objective of this study was to identify the major areas where SRC-fired and coal-fired power plants differ in capital cost. Total Plant Investments expressed in 1978 dollars for twin 500 MW units located in Wisconsin and meeting 1976 NSPS were 582 $/kW for an SRC-fired plant and 743 $/kW for a bituminous coal-fired plant. Inclusion of AFDC, startup, and fuel inventory capital raises the Total Capital Requirement to 728 $/kW and 906 $/kW for the SRC-fired and the coal-fired plants, respectively. On a total plant investment basis, the SRC-fired plant is 22% lower in cost than the coal-fired plant. The elimination of the flue gas desulfurization unit from the SRC-fired plant is the major area of cost saving contributing 19% of the 22% difference. More stringent emission standards increase the cost of both types of plant and reduce the capital cost differential. Capital costs associated with retrofitting a 500 MW oil-fired plant to fire solid SRC or an SRC/oil slurry were also developed. Expressed in 1978 dollars, the total capital requirement for retrofit was 175 $/kW for solid SRC-firing and 73$/kW for SRC/oil slurry firing.
