Notes:
• NERC region and reliability assessment area maps are provided on EIA's Electricity Reliability web page: http://www.eia.gov/cneaf/electricity/page/eia411/eia411.html
• Projected data are updated annually.
• Peak load represents an hour of a day during the associated peak period.
• The Summer peak period begins on June1 and extends through September 30.
• The Winter peak period begins October 1 and extends through May 31.
• Historically the MRO, RFC, SERC, and SPP regional boundaries were altered as utilities changed reliability organizations. The historical dataseries for these regions have not been adjusted. Instead, the Balance of Eastern Region category was introduced to to provide a consistenttrend of the Eastern interconnection.
• ECAR, MAAC, and MAIN dissolved at the end-of-2005. Many of the former utility members joined RFC. ReliabilityFirst Corporation (RFC) came into existence on January 1, 2006. RFC submitted a consolidated filing covering the historical NERC regions of ECAR, MAAC, and MAIN.
• E - Estimate;
NA - Not Available
