DeMoss Petrie (DMP) to Tucson
DeMoss Petrie (DMP) to Tucson April 15, 2009 1 1 Project Overview
Project Overview • TEP is proposing to construct a 138-kV transmission line from the DMP Substation, located east of Interstate 10 (I-10) and north of Grant Road, to the Tucson Substation, located east of 11th Avenue between 4th Street and the Union Pacific Railroad • Planning process: environmental studies and public outreach will be conducted to assist in identification and comparison of alternative transmission line routes and environmental impacts • Project requires review by the Arizona Corporation Commission’s (ACC) Power Plant and Transmission Line Siting Committee, resulting in a recommendation to and a final determination by the ACC prior to construction • Anticipated in-service date: mid-2010 2 2 Purpose and Need
Purpose and Need • Provide 138-kV transmission capability between the DMP and Tucson substations • Improve system reliability for customers in the western portion of the Tucson area • Existing transmission lines could not serve this purpose 3 3 Project Description
Project Description • A 138-kV transmission line from the DMP Substation, located east of Interstate 10 (I-10) and north of Grant Road, to the Tucson Substation, located east of 11th Avenue between 4th Street and the Union Pacific Railroad • Depending upon its final route, the project could be several miles in length • Potential to use existing 46-kV line rights-of-way • In accordance with TEP’s design standards, the transmission line structures would be built to accommodate a second circuit (138- or 46-kV) • A 100-foot-wide right-of-way required when not in road • Upgrades to existing substations will not require additional property 4 4 Proposed Structure Type
