Greenville Utilities Recognized as a Reliable Public Power Provider

Greenville Utilities (GUC) has once again earned a Reliable Public Power Provider (RP3)® Diamond Level designation from the American Public Power Association for providing reliable and safe electric service.  The Diamond Level is the highest designation and places GUC in the top 10% of all community-owned power utilities in the nation.

RP3 LogoThe RP3 designation, which lasts for three years, recognizes public power utilities that demonstrate proficiency in four key disciplines: reliability, safety, workforce development, and system improvement. Criteria include sound business practices and a utility-wide commitment to safe and reliable delivery of electricity. GUC is one of 270 public power utilities nationwide that hold the RP3 designation and one of just 127 at the Diamond Level. 

“I think over the last year or so, we’ve seen the vital importance of running a reliable and safe utility,” says Aaron Haderle, Chair of APPA’s RP3 Review Panel and Manager of Transmission and Distribution Operations at ‎Kissimmee Utility Authority, Florida. “The utilities receiving the RP3 designation have proven that they are committed to running a top-notch public power utility by implementing industry best practices.”  

“We couldn’t be prouder to be honored with this designation,” said John Worrell, GUC Director of Electric Systems. “This is a prestigious recognition of a lot of work from a lot of people who really care about powering our community. And this designation is not a final destination. We are committed to continuing to look for ways to improve our operations and service to our customers.” 

General Manager / CEO Tony Cannon said, “This designation shows the ongoing commitment to the Greenville region by our Board and our employees. It also shows the great value that only a community-owned utility provides through local control resulting in very high reliability and safety, as well as the investments we make in our systems and employees.”

Greenville Utilities has been recognized with the RP3 designation continuously since 2007, having earned the Diamond Level distinction in 2018 and again in 2021.


The American Public Power Association has offered the RP3 designation for 15 years. APPA is the voice of not-for-profit, community-owned utilities, including GUC, that power 49 million people in 2,000 towns and cities nationwide. APPA advocates and advises on electricity policy, technology, trends, training, and operations.
