Similar to how the American highway system connects towns and cities across the United States, the electric transmission system is responsible for transporting high-voltage electricity from power generating facilities to areas where electricity is needed. It is an extensive system of interconnected networks that is vital to the US economy and our everyday lives.
Transmission lines on Westar Energy’s system are defined as lines 69 kV (69,000 volts) and above. The structures that support the transmission lines are commonly steel towers, single large poles and wooden h-frames. You’ve probably noticed the size of these large lines as you are driving down the highway.
Westar Energy operates and maintains 6,300 miles of transmission lines and about 28,100 miles of distribution lines (34,500 volts and below) that provide safe, reliable electricity to nearly 700,000 customers.
