Documentation Summary for EPA Base Case 2004 Using IPM (V.2.1.9) (2004 Update)

To learn more about EPA Base Case 2004 and the updates, changes, and enhancements that were implemented, you can view and download the 2004 documentation report by chapter below. This standalone version of the documentation replaces an earlier version which contained tables of only those assumptions that were updated. With this version of the documentation the reader can refer to a single source for a discussion of all modeling assumptions and will no longer have to refer to earlier documentation for a discussion of assumptions that had not changed.

National Electric Energy Data System (NEEDS)

The NEEDS database contains the generation unit records used to construct the "model" plants that represent existing and planned/committed units in EPA modeling applications of IPM. NEEDS includes basic geographic, operating, air emissions, and other data on these generating units. For more information about NEEDS, visit National Electric Energy Data System (NEEDS) 2006.
