Chambersburg’s Electric Utility, Pennsylvania’s largest municipal electric system, received national recognition for achieving exceptional electric reliability in 2024. The recognition comes from the American Public Power Association (APPA), a trade group that represents more than 2,000 not-for-profit, community-owned electric utilities.
APPA helps electric utilities track power outage and restoration data through its subscription-based eReliability Tracker service. Once per year, APPA’s Reliability Team compares this data to national statistics tracked by the U.S. Energy Information Administration for all types of electric utilities.
“Year after year, data consistently demonstrate public power utilities provide highly reliable service.” said APPA Director of Research and Development Paul Zummo. “Utilities like Chambersburg are truly elite when it comes to keeping the lights on. Their communities should be proud of the hard work and dedication of their local power providers as they earn this truly deserved recognition.”
Nationwide, the average public power customer has their lights out for less than half the amount of time that customers of other types of utilities do.

“We are proud to receive this recognition. It is a testament to the hard work of all our staff to ensure that we keep the lights on in Chambersburg homes and businesses,” said Jeffrey Stonehill, Borough Manager, and Director of Utilities.
“There are many ways that Chambersburg stands out compared to every other electric system,” added Council President, Allen Coffman. “Including that Chambersburg has the second lowest retail electric rates in the State.”
“However,” pointed out Electric Utility Director Jeff Heverley, “nothing is more important than saving our residents and businesses thousands of dollars every year and having the power out some of the shortest times in the Country.”

Chambersburg, on average, had interrupted power of only 18-minutes in 2024 and 9-minutes in 2023 per year per customer. Most major Pennsylvania utilities average 82-minutes to 183-minutes per year per customer; according to the most recent 2023 EIA published SAIDI (System Average Interruption Duration Index) statistics.
