[1] Distributed generator data in 2005 include a significant number of generators reported by one respondent, which may be for residential applications.
Note: Dispersed and distributed generators are commercial and industrial generators. Dispersed generators are not connected to the grid. Distributed generators are connected to the grid. Both types of generators may be installed at or near a customer`s site, or at other locations, and both types of generators may be owned by either the customers of the distribution utility or by the utility. Other includes generators for which technology is not specified.

* During these years, generators above 1 MW were also counted. This changed in 2010 when only generators smaller than 1 MW were counted.
