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

PHILADELPHIA–(BUSINESS WIRE)–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.
