Smart Grid reduces impact of February 12 snow storm


Chattanooga, TN (February 19, 2014) – The community’s Smart Grid prevented an additional 40,000 homes and businesses from losing power during last week’s snow storm, resulting in a 52% reduction in weather related outages.

During the three day event about 76,000 customers were affected, but the Smart Grid automatically restored 40,000 customers within a few seconds or minutes. About 36,000 homes and businesses experienced outages that needed restoration by EPB crews.

The widespread power outages were caused by up to 10 inches of snow bringing down trees and limbs on EPB power lines. EPB crews worked 16 to 30 hour shifts with help from contractors and numerous other utilities.

  • EPB brought in 178 additional line and tree crews with 685 people.
  • EPB received help from 24 different utilities through the Tennessee Valley Public Power Association mutual aid agreement, and eight independent contractors and crew brokers.
  • EPB booked 372 hotel rooms for out-of-town-crews.
  • EPB kept 60 generators fully operational throughout the storm event for medically registered customers.
  • EPB received about 46,000 customer calls during the three-day storm event.

“It’s good to see the Smart Grid delivering consistent results that benefit our community,” EPB President and CEO Harold DePriest said. “In addition to the Smart Grid, we are thankful for all the assistance from out-of-town crews who helped restore our community’s electric system.”
