SDG&E Transmission Lines

The purpose of the Geographic Information Systems (GIS) data is for both the electrical corporations and Energy Safety to have a holistic understanding of the electrical corporation infrastructure, annual targets as reported in its WMP, and quarterly planning and progress for each initiative. These data enable Energy Safety to evaluate the electrical corporation's WMP and compliance. All data in the Transmission Line feature class represents the as-built electric data model, the data represents the active and active to be removed Transmission Lines as at the time the data is extracted from PRO_VAQ_ELEC (approximately 1 month prior to submission date). The data does not contain preliminary segments as they do not physically exist as the time of the data extract.
