Transmission Constraints and Congestion in the Western and Eastern Interconnections, 2009-2012 (January 2014)

The "Transmission Constraints and Congestion in the Western and Eastern Interconnections, 2009-2012" document, available below, is a compilation of publicly-available data on transmission constraints and congestion for the period 2009 through 2012. Providing relevant transmission data available to the public in a timely manner will aid the development of worthwhile public and private analyses on a range of electricity topics. The Department intends to release a stand-alone transmission data document annually, rather than combining it with the triennial congestion studies.

Note: this is not the Department's third National Electric Transmission Congestion Study, which will be released separately.
