In order <strong>to</strong> bring electricity <strong>to</strong> its cus<strong>to</strong>mers, a utility<br />
such as Idaho Power needs <strong>to</strong> transport electrical<br />
power from traditional generating resources like<br />
hydro-electric dams or thermal power plants as well<br />
as other merchant facilities and renewable resources<br />
such as wind and geothermal across long distances.<br />
To do that, high voltage transmission lines are used,<br />
which would be the equivalent of a freeway system that<br />
moves vehicle traffic. Once the electricity arrives at a<br />
community it goes <strong>to</strong> a substation, where the voltage<br />
is stepped down—like an off-ramp from the freeway<br />
and slowing down for street traffic. From there it goes<br />
out on distribution lines—or feeders—<strong>to</strong> serve local<br />
businesses and homes.<br />

The whole process can take electricity from very<br />
high voltages down <strong>to</strong> the 110 or 220 volts that most<br />
residents are familiar with. And it all happens in less<br />
than a second!<br />
