What is a Substation?

Substations are facilities where voltage transformation takes place. Substations are where electricity is typically transferred from high-voltage transmission lines (energized at 100,000 volts), stepped down to 7,000 volts, and then sent back out on main distribution lines that carry it to local towns and neighborhoods.

Union Power currently has 23 substations. Each of these substations have between 4 – 10 circuit breakers that send power out to circuit lines serving the locations on our system. Click on image below to explore a substation.
