Structures and substations
High voltage direct current structures have various configurations, and specific structure types for the Zephyr projects have not yet been identified.
Here are some sample HVDC structures. HVDC structures carry two wires, can be 115 to 135 high, and require a right-of-way width of approximately 250 feet.
At a converter station, electricity is converted from alternating current to direct current, or vice versa
