“Fear that utility companies remain vulnerable to hackers, terrorists and natural disasters has the Pentagon pushing construction of independent power grids at military bases across the U.S., including one nearing completion here at the Marine Corps combat center.
The base at Twentynine Palms, home to about 22,000 people and spread across 1,100 square miles of the Mojave Desert, still buys power from Southern California Edison. But soon it will be able to operate even if there is a blackout, using a system of small power plants, solar panels, batteries and diesel generators. It already is saving $10 million a year in energy costs.”
