Companies Unplug From the Electric Grid, Delivering a Jolt to Utilities


Thanks to Matt for passing this along.

On a hill overlooking the Susquehanna River, two big wind turbines crank out electricity for Kroger Co.'s Turkey Hill Dairy in rural Lancaster County, Pa., allowing it to save 25% on its power bill for the past two years.

Across the country, at a big food-distribution center Kroger also owns in Compton, Calif., a tank system installed this year uses bacteria to convert 150 tons a day of damaged produce, bread and other organic waste into a biogas that is burned on site to produce 20% of the electricity the facility uses.

These two projects, plus the electric output of solar panels at four Kroger grocery stores, and some energy-conservation efforts are saving the Cincinnati-based grocery chain $160 million a year on electricity, said Denis George, its energy manager. That is a lot of money that isn't going into the pockets of utilities.

From big-box retailers to high-tech manufacturers, more companies across the country are producing their own power. Since 2006, the number of electricity-generation units at commercial and industrial sites has more than quadrupled to roughly 40,000 from about 10,000, according to federal statistics.

Experts say the trend is gaining momentum, spurred by falling prices for solar panels and natural gas, as well as a fear that power outages caused by major storms will become more common.
