Peaking power plants provide electricity only when our customers' electric needs
reach a "peak." These plants can be started and shut off by remote control in a
matter of minutes.
Jet engines used as peaking units are similar to the engines in jet aircraft. Diesel
engines used for this purpose are much like the engines in railroad locomotives.
Because peaking plants run on more expensive fuels, they are used only during times
of need and are immediately shut off when the need for electricity declines.
The fuel used by the peaking plants burns cleanly, minimizing pollutants in the
environment.
