2006 Congestion Study
Section 216(a) of the Federal Power Act requires the Department of Energy to issue a national transmission congestion study (Congestion Study) for comment by August 2006 and every three years thereafter.
The Congestion Study issued on August 8, 2006 is the Department of Energy's first congestion study. It examines transmission congestion and constraints and identifies constrained transmission paths in many areas of the Nation, based on examination of historical studies of transmission conditions, existing studies of transmission expansion needs, and unprecedented region-wide modeling of both the Eastern and Western Interconnections.
Public comment documents submitted for the National Electric Transmission Congestion Study are available for online browsing or downloading.

The next Congestion Study is due August 8, 2009. A Web site for the 2009 National Electric Tranmission Congestion study is available.
