Next Steps Notice of Intent to Consider Designation of National Corridors For the two areas identified above as Critical Congestion Areas, the Department believes it may be appropriate to designate one or more National Corridors to facilitate relief of transmission congestion in these areas. The Department will also consider designating National Corridors to relieve constraints or congestion in Congestion Areas of Concern and Conditional Congestion Areas. The Department requests comments from stakeholders on three questions by October 10, 2006: • Would designation of one or more National Corridors in relation to these areas be appropriate and in the public interest • How and where should DOE establish the geographic boundaries for a National Corridor • To the extent a commenter is focusing on a proposed transmission project, how would the costs of the facility be allocated (Although the question of cost allocation for a transmission project is not directly related to the designation of a National Corridor, DOE recognizes the criticality of cost allocation issues and is interested in how they might be resolved.) Chapter 6 provides additional discussion of these questions and information on where comments should be filed. After evaluating the comments received, the Department may proceed to designate some areas as National Corridors, seek additional information, or take other action. Role of regional transmission planning organizations in finding solutions to congestion problems DOE expects that regional transmission planning organizations will continue to show leadership in working with stakeholders and transmission experts to develop solutions to the congestion problems identified above in their respective areas. DOE expects these planning efforts to be inter-regional where appropriate, because many of the problems and likely solutions cross regional boundaries. In particular, the Department believes that these analyses should encompass both the congestion areas and the areas where additional generation and transmission capacity are likely to be developed. The Department will support these planning efforts, including convening meetings of working groups and working with the Federal Energy Regulatory Commission and congestion area stakeholders to facilitate agreements about cost allocation and cost recovery for transmission projects, demand-side solutions, and other subjects. DOE anticipates that regional—and inter-regional, where appropriate—congestion solutions will be based on a thorough review of generation, transmission, distribution and demand-side options, and that such options will be evaluated against a range of scenarios concerning load growth, energy prices, and resource development patterns to ensure the robustness of the proposed solutions. Such analyses should be thorough, use sound analytical methods and publicly accessible data, and be made available to industry members, other stakeholders, and Federal and state agencies. Annual congestion area progress reports Each of the congestion areas identified above involves a somewhat different set of technical and policy concerns for the affected stakeholders. The Department will work with FERC, affected states, regional planning entities, companies, and others to identify specific problems, find appropriate solutions, and remove barriers to achieving those solutions. The Department intends to monitor congestion and its impacts in these areas, and publish annual reports on progress made in finding and implementing solutions. The Department plans to issue its first progress report by approximately August 8, 2007, the second anniversary of the enactment of the Energy Policy Act of 2005. x U.S. Department of Energy / National Electric Transmission Congestion Study / 2006
