Conceptual designs and order-of-magnitude capital cost estimates, including expenditure schedules, have been prepared for conventional 330 MW and 500 MW pulverized coal-fired power plants located in Kenosha, Wisconsin, near an urban center, and Hermiston, Oregon, in a remote location. The plants have been designed and estimated for burning low-sulfur subbituminous Wyoming coal. The capital cost estimates are at end-of-year 1984 price level with no escalation and are based on the contractor's current construction projects and vendor pricing. Conservative estimating parameters, based on EPRI reports PE-1865 and P-2410-SR, have been used to ensure their suitability as planning tools for utility companies. The estimated total capital requirements range from $1,220 /kW for twin-500 MW units at Kenosha to $1,830/kW for a single-330 MW unit at Hermiston. Summary engineering/procurement/construction site-specific schedules are presented and reflect current industry trends for design, fabrication, delivery and erection of major plant components and differences in bulk material quantities. Accelerated schedules were developed to incorporate changes in procudures and/or practices that will shorten construction time, and the cost impacts and feasibility were assessed. Estimated of manual labor requirements and labor curves were also prepared. Findings show that a replicated plant built on Rolling 4 x 10's (70 hour workweek) would offer the shortest project schedule and be a superior choice if captial cost were the primary consideration. An overall schedule shortening of about four months would be achieved and corresponding reduction of $45 million or three percent of total capital requirements. An assessment of the effects of ten cases of deferral and/or cancellation ranging from six months before site work starts to two years after site work starts when engineering or construction is already in progress was performed. 12 refs., 41 figs., 37 tabs.
