Description: The Transmission Lines feature class is a GIS file depicting market significant electric power transmission lines in North America. Included lines generally have a capacity of greater than 69 kilovolts. Features in this feature class often represent multiple circuits. Some features have been created in order to link major features from the Electric Power Generation Plants feature class to the electrical grid through the associated feature from the Substations feature class. The Transmission Lines feature class contains existing and proposed features. Features that are currently operational can be isolated by examining the PROPOSED field for an "In Service" attribute.
