EPRI GTC Tailored Collaboration Project: A Standardized Methodology for Siting Overhead Electric Transmission Lines

摘要

A team sponsored by the Electric Power Research Institute (EPRI) and Georgia TransmissionCorporation (GTC) conducted a two-year study of transmission line siting and produced a newapproach for making siting decisions more quantifiable, consistent and defensible. Using GTC'sexisting transmission line siting process, the study incorporated GIS technology, statistical evalu-ation methods and stakeholder collaboration to produce a new siting methodology. The tools,techniques and procedures developed by the team were demonstrated through practical ap-plication on construction projects. An EPRI-GTC Overhead Electric Transmission Line SitingMethodology report will be published soon that describes how the team: 1.Developed a new GIS siting model and management procedures for producing more objective,quantifiable and consistent siting decisions; 2.Obtained more than 400 stakeholders' critical reviews and achieved consensus on the rankingof geographic, land use, environmental, engineering and other GIS database features, as wellas the weighting of data layers; 3.Ensured the process conforms to environmental laws; and 4.Revised Georgia Transmission's existing overhead transmission line siting practice.The team produced a standardized process that other utilities can use to improve the waytransmission lines are sited.
