Power coming from remote power plants requires the use of high-voltage power lines.
Voltage running through power lines in Austin's outer areas can be as high as 345 kilovolts. In suburban areas, voltage running through the power lines is typically 138 kilovolts. These high-voltage transmission lines are supported by transmission towers and travel through substations. The towers that support high voltage transmission lines are attractive to kids, because they look like a ladder. But, the towers are dangerous to climb.
