PPL Electric Utilities unveils automated power restoration system

A new automated power restoration system is turning the lights back on for PPL Electric Utilities customers in minutes, even before a work crew has made repairs.

The system led to significantly shorter power outages for thousands of homes and businesses in two recent rounds of thunderstorms.

The PPL smart grid uses advanced technology that includes pole-top sensors to detect outages, a central computer that quickly analyzes the problem, and remote-control switches that reroute power and restore many affected customers to service.

“Our goal is to provide exceptional service for our customers, and this new technology is one key way we are doing that,” said David Quier, the utility’s operations director.

During severe thunderstorms the week of July 18, the PPL smart grid restored 9,488 homes and businesses to service in an average of one minute and 56 seconds. The following week, during another round of severe storms, the technology restored 5,308 customers automatically in an average of one minute and 36 seconds.

Automated power restoration is the latest in a series of reliability improvements made by PPL. Other ways the company is improving service for customers include making lines and equipment more stormproof, installing guards to keep squirrels and other animals from causing outages, and expanded tree trimming, because trees are the major cause of outages during storms.

The result has been a 30 percent reduction in the number of power outages since 2007, with another 15 percent fewer outages expected in the next five years. During 2015, PPL Electric Utilities reliability programs prevented an estimated 410,000 power outages for customers.

“In the coming years, we will install another 1,000 smart grid sensors and automated switches around PPL’s service territory,” Quier said. “This will make the PPL smart grid system even more effective, further improving the reliability of our service for customers.”
