DOE hosted six regional pre-study workshops in mid-2008 to receive input and suggestions concerning the 2009 National Electric Transmission Congestion Study, including comments on practical metrics for gauging levels and significance of transmission congestion. Each workshop featured a panel of invited speakers to present their views and comments. For details, including agendas, transcripts, and documents submitted for consideration for the 2009 study, please select a workshop, below.

DOE also hosted a technical workshop on March 25-26, 2009 to receive input from subject matter experts on the historical transmission data and studies of future transmission projections in the Western and Eastern Interconnections.
