This feature class/shapefile represents electric power substations primarily associated with electric power transmission. In this layer, substations are considered facilities and equipment that switch, transform, or regulate electric power at voltages equal to, or greater than, 69 kilovolts. Substations with … Continued
This layer represents electric power transmission lines. Transmission Lines are the system of structures, wires, insulators and associated hardware that carry electric energy from one point to another in an electric power system. Lines are operated at relatively high voltages … Continued
This layer displays the locations of the Environmental Protection Agency (EPA) Emissions & Generation Resource Integrated Database (eGRID) sites. The eGRID is a comprehensive source of data on the locations and environmental characteristics of almost all electric power generated in … Continued
