  [1] ECAR, MAAC, and MAIN dissolved at the end-of-2005.  Utility membership joined other reliability regional councils.  Also, see Footnote 3.
  [2] Regional name has changed from Mid-Continent Area Power Pool to Midwest Reliability Organization.
  [3] ReliabilityFirst Corporation (RFC) came into existence on January 1, 2006, and submitted a consolidated filing covering the historical NERC regions of ECAR, MAAC, and MAIN.  Many of the former utility members joined RFC.
  NA = Not available. 
  Notes: Projected data are updated annually, so revision superscript is not used. NERC Regional Council names may be found in the Glossary reference. Represents an hour of a day during the associated peak period. The summer peak period begins on June 1 and extends through September 30. The winter peak period begins on December 1 and extends through end-of-February of the following year The MRO, SERC, and SPP regional boundaries were altered as a variety of utilities changed reliability organizations.  The historical data series have not been adjusted. Totals may not equal sum of components because of independent rounding.
