This report presents the results of a study conducted by Fluor Engineers, Inc. for EPRI to develop a current estimate of the performance and cost of a mature, Texaco-based integrated coal gasification-combined-cycle (IGCC) power plant. Both Texaco, Inc. and the General Electric Company were major participants during the entire course of the effort. Consequently, all designs presented in this study use the most recent data available from Texaco's ongoing international coal gasification development program and General Electric's continuing gas turbine development efforts. Three basic IGCC plant configurations were studied. The major difference in these configurations is the level of heat recovery from the gas immediately downstream of the gasifier. A major conclusion of this comprehensive study is that Texaco-based IGCC power plants have the potential to be 10% more efficient than conventional subcritical coal-fired steam plants designed to comply with current federal environmental regulations when firing Illinois No. 6 coal. Furthermore, the IGCC systems have the potential to be capital cost competitive with conventional coal-fired steam plants while providing up to 15% reductions in levelized costs of electricity as well as substantial reductions in both SO/sub x/ and NO/sub x/ emissions. The report has been prepared in two volumes. Volume 1 provides an overall summary and discussion of the major results. Volume 2 includes the design, performance, cost, and other backup details that were used in arriving at the results and conclusions presented in Volume 1. 19 figures, 9 tables.
