1. July 17, 2008 1 GRAC 7/17/08 - Wrap-up I 1)Are the reference plant assumptions reasonable? More or less specificity? Important variations? 2)Should other reference plants be considered (e.g. GE LMS-100)? 3)Are the analyses and conclusions credible; how could they be improved? 4)Is there a better approach to discussing the assumptions? 5)Should we try to schedule presentations by outside experts? If so, what topics, who?

2. July 17, 2008 2 GRAC 7/17/08 - Wrap-up II 6)Do additional characteristics need to be assessed (e.g., Energy 2020 new resource parameters)? 7)Should we include figure-of-merit capacity and energy costs at this point. If so, what financing, power delivery & timing assumptions should we assume? 8)How should we approach the assessment of storage & ancillary service alternatives? What alternatives should we consider? 9)Other future agenda items?

3. July 17, 2008 3 Reference combined-cycle plant (5 th plan) Natural gas-fired combined-cycle combustion turbine power plant. 2 GT x 1 ST w/duct firing configuration. 540 MW (nominal) baseload; 610 MW peak (w/duct firing). Rural site, no cogeneration load. Mainline fuel gas service w/no fuel gas compression required. Low-NOx combustors and SCR for NOx control. CO2 catalyst. Wet mechanical draft cooling. Generally based on GE FA technology.
