Path 27, also called the Intermountain or the Southern Transmission System, is a high-voltage direct current electrical transmission line running from the Intermountain Power Plant near Delta, Utah, t
Path 27 as seen on US 50 in Utah. An AC transmission line has since been built alongside this segment of the HVDC line.
Path 27 may be identified by its uniquely-designed steel lattice pylons and two conductors. The tower's height, insulation, and separation of conductors and their thickness meet the specifics for a 500-kV circuit. Compare to a lower-voltage, conventional three-phase power line on the right.
The Adelanto Converter Station is the end point of the HVDC line.
Path 27 uses stacks of thyristor valves similar to these on the HVDC Inter-Island in New Zealand. Note the person for scale.
An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy along large distances. It consists of one or more conductors suspended by tower

…cities, the largest member being the Los Angeles Department of Water and Power (LADWP), and 29 smaller Utah municipalities. Path 27 consists of an overhead power line 488 miles (785 km) long, and is capable of transferring up to 2,400 megawatts (MW) of power at ±500 kilovolts (kV), higher than the power plant's…
