2008 Corporate Sustainability Report 51 mission lines. The project is slated to start at AEP’s Amos substation near St. Albans, W.Va., and run to Allegheny’s Bedington substation, near Martinsburg, W.Va. Another 46 miles will consist of 500 kV transmission lines from Bedington to a new station to be built near Kemptown, near Frederick, Md. The Kemptown segment will be owned solely by Allegheny Energy. Siting studies for these projects are expected to begin in 2008. While PATH has received approval from PJM Interconnection LLC, the regional transmission organization responsible for transmission planning for the area, state and local approvals must still be obtained. PJM has identified the corridor as an area in critical need of additional transmission capacity and has requested that the new line be in service by 2012. In addition, the PATH project falls within an area that has been designated by the DOE as a National Interest Electric Transmission Corridor, which recognizes the need to address reliability and congestion concerns in the region. AEP believes that completing PATH will improve energy efficiency and provide greater reliability while reducing high congestion costs for the eastern PJM region. We also received regulatory approvals to form a joint venture with MidAmerican Energy Holdings Co., known as Electric Transmission Texas (ETT). We have begun assigning major transmission projects to ETT and we also advocated a proposal to build 1,000 miles of transmission lines in Texas to support the state’s development of its Competitive Renewable Energy Zones. We also signed an agreement with ITC Transmission to evaluate the feasibility of extending 765 kV lines through Michigan. In response to the growing importance of these opportunities to expand the nation’s EHV system, the transmission organization was reorganized to report directly to AEP’s chairman. GENERATION & PLANT EFFICIENCY AEP’s plans to build two ultra-supercritical coal plants met with only partial success. The John W. Turk Plant was approved in Arkansas and Louisiana and now awaits approval in Texas. This facility will use the latest technology to create electricity more efficiently than traditional coal plants. AEP believes that coal must remain part of the nation’s generation because of its availability, consistent performance and low cost. This technology is an important part 765 kV Line Footprint Energy Security, Reliability & Growth 765 kV transmission maximizes land use, providing the greatest capacity increases and requiring the least amount of land. 345 kV Six Single-Circuit Towers 900 ft.
