Direct Transmission Line by State

This map shows DC (direct current) transmission lines within the U.S. All transmission lines are shown as faint gray lines, with the DC lines bolded. States without a color do not have DC transmission lines within their border, with the state color corresponding to the total length of DC transmission within that state. Individual state lengths are plotted in the bar chart below.
