Section 1221(a) of the Energy Policy Act of 2005, codified at 16 U.S.C. 824p(a), directs the Secretary of Energy to conduct an electric transmission congestion study every three years, and to prepare it in consultation with affected states and regional reliability organizations. In the study, the Department seeks to provide information about transmission congestion by focusing on specific indications of transmission constraints and congestion and their consequences. The study focuses on a specific time frame – e.g., historical trends over the past few years, and looking forward three to five years. The study is based entirely on publicly-available data and transmission-related documents. The Department has published two previous congestion studies, one in 2006 and another in 2009.
In preparing for the current congestion study, the Department published a Federal Register Notice, requesting comments on what publicly-available data and information should be considered, and what types of analysis should be performed to identify and understand the significance and character of transmission congestion. The Department then conducted a series of four regional pre-study workshops to receive input and suggestions concerning the Study, followed later by a series of webinars during which preliminary findings were shared with state officials and other stakeholders and input was requested.
On August 19, 2014, the Department issued a Federal Register Notice announcing the availability of a draft of its National Electric Transmission Congestion Study for public comment. The public comment period will close on October 20, 2014. The draft study is now available for review and downloading.
Written comments may be submitted electronically to Congestionstudy.firstname.lastname@example.org. Written comments may also be delivered by conventional mail to David Meyer, Office of Electricity Delivery and Energy Reliability, U.S. Department of Energy, 1000 Independence Ave., SW, Washington, DC 20585. Commenters are cautioned, however, that all conventional mail to the Department is subject to an automatic security screening process that may take up to three weeks and sometimes renders mailed material illegible. Comments will be posted online.
After reviewing and considering comments on the draft study, the Department will prepare and release a final version of the study.
