• No frequency matching issues between systems.
• DC systems appears as an open circuit to AC systems, limiting the spread of faults.
• Less expensive towers and wires.
• No reactive losses.
• No line length limits. Apparently AC has problems with lines longer than half a wavelength (2500 km or 1500 miles).
