PECO Completes $32 Million Substation in Marcus Hook to Support Increased Demand and Future Growth

​PHILADELPHIA (December 19, 2016) – PECO recently completed construction of a new $32 million electric distribution substation to support increased demand and future growth in Marcus Hook, Delaware County.

The project, which began in August 2015, incorporated the latest innovations in smart substation technology to provide customers with enhanced electric service reliability. This includes the installation of fiber-optic current transformers and diagnostic systems that process real-time analysis of transformers, circuit breakers and battery systems. In addition, thermal imaging is used to identify potential issues before they occur by recording temperature variations within a piece of equipment while in operation.

"This project is another significant investment designed to enhance our electric system to meet the needs of our customers," said Dave Weaver, vice president of Technical Services. "In addition, we will be able to leverage new, innovative solutions and advanced analytics to anticipate maintenance issues to avoid customer outages."

Electric distribution substations convert high voltage electricity from transmission lines into lower voltages for delivery to homes and businesses. Each year, the company invests more than $500 million to enhance its system infrastructure through preventive maintenance and equipment upgrades to ensure safe and reliable service for customers.
