FEDERAL POWER ACT 1. Introduction **** Sec. 216. SITING OF INTERSTATE ELECTRIC TRANSMISSION FACILITIES (a) DESIGNATION OF NATIONAL INTEREST ELECTRIC TRANSMISSION CORRIDORS—(1) Not later than 1 year after the date of enactment of this section and every 3 years thereafter, the Secretary of Energy ...,in consultation with affected States, shall conduct a study of electric transmission congestion. (2) After considering alternatives and recommendations from interested parties (including an opportunity for comment from affected States), the Secretary shall issue a report, based on the study, which may designate any geographic area experiencing electric energy transmission capacity constraints or congestion that adversely affects consumers as a national interest electric transmission corridor. **** Section 1221(a) of the Energy Policy Act of 2005 added section 216 to the Federal Power Act (FPA), which directs the Secretary of Energy (the Secretary) to conduct a nationwide study of electric transmission congestion within one year after the date of enactment (i.e., by August 8, 2006) and every three years thereafter. 2 The Secretary is also directed to issue a report based on the congestion study in which he may designate “any geographic area experiencing electric energy transmission capacity constraints or congestion that adversely affects customers as a national interest electric transmission corridor.” As specified in FPA section 216(a)(4), the Secretary, in exercising his authority to designate a national interest electric transmission corridor (“National Corridor,” or “Corridor”), may consider the economic vitality and development of the corridor and markets served, the economic growth of the corridor and its end markets, including supply diversification and expansion, the Nation’s energy independence, national energy policy, and national defense and homeland security. As directed in the law, this study examines congestion and transmission constraints in the U.S. portions of the Eastern and Western Interconnections, but does not address the Electric Reliability Council of Texas, which is a third interconnection. (See Figure 1-1 for a map of the three interconnections, which together comprise the bulk power system in the U.S., much of Canada, and a small portion of Mexico.) Although this analysis does not address congestion and constraints outside the U.S., data on Canadian electricity generation, transmission, demand, cross-border flows, etc. were incorporated into the modeling conducted for the study because 2 See Appendix A for the full text of section 1221(a) and (b).
