### Table 1. Unit Characteristics

Field Name Description Plant Name Plant name ORIS Facility ORIS code Unit ID Unit ID State State name

NEEDS ID Unique identifier in National Electric Energy Data System (NEEDS) v3.02 EISA, which is used in IPM modeling. Blank for units not included in NEEDS v3.02 EISA.

Capacity (MW) Net summer generating capacity. Blank for units not matched to NEEDS, which are assumed to be greater than 25 MW.
Projected-Reported Relationship Number of NEEDS units mapped to source of reported data. Typically, the relationship is 1:1. Where 2 or more NEEDS units are mapped to a single unit reporting data, the emissions are divided evenly between the NEEDS units. Committed SCR - 2010- 2011 SCR expected online in 2010-2011
