Transmission Voltages under 100kV

This map shows transmission lines across the U.S. with voltages under 100kV. All transmission lines are shown as faint gray lines, with the <100kV lines bolded. State color corresponds to the total length of <100kV transmission within that state. Individual state lengths are plotted in the bar chart below.
