15 Closing Summary Utilizing western coals close to their source of origin (e.g., high elevation, limited water availability) can result in technology selection ect factors very different e than the same plant at a different e location, i.e., one size does not fit all. Even with low rank coals, IGCC technologies take less of an efficiency hit when adding CCS compared to combustion technologies. Using LCOE as the metric for comparison, there is no clear advantage for either IGCC or combustion plants with CCS. In many areas of the country, new coal, with or without CCS, results in significantly higher electricity costs compared to existing assets. Final Report expected late 2009 On the web at html 15
