National Electric Energy Data System (NEEDS)
The National Electric Energy Data System or “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 a description of the sources used in preparing NEEDS, see Documentation, Chapter 4: Generating Resources (pdf) . [For versions of NEEDS prior to the rev 6-21-22, see Documentation] For how to send us feedback on NEEDS, see the User Guides.
