Fort Knox again will demonstrate its energy independence by going off the grid Wednesday.
Leaders from the Department of the Army and U.S. Department of Energy will witness the test, which begins at 10 a.m. Fort Knox currently is the only U.S. military installation able to power itself indefinitely without external resources.
Fort Knox creates power by converting natural gas, extracted from underneath the installation, into electricity at power-generating sites on the reservation. In conjunction with diesel generators, the post can produce enough energy to power the installation when needed to ensure continuous operations of installation and its global missions.
Besides periods of emergency use, Fort Knox uses the generators to produce its own power when energy demand strains power plants outside the post and premiums are at their highest, resulting in savings of about $7 million annually.
The Fort Knox energy team first proved its energy independence last October with a similar test of its Energy Security Program.
