a Information summarized from Edison Electric Institute (2011) table and footnotes. Note: this information source states that "because some plant closure details and/or plans for
replacement generation have not been finalized, it is not possible to determine the exact number of closures, the mix and quantity of generation replacing the retiring coal units". b Information added form Chicago Tribune, Feb. 29, 2012 article by Hawthorne and Mack.
