Peco has completed construction of a new $32 million electric distribution substation in Marcus Hook to support increased demand and future growth, including new development at the Marcus Hook Industrial Complex.
The project, which began in August 2015, includes installation of fiber-optic current transformers and diagnostic systems that provide a real-time analysis of the substation's transformers, circuit breakers, and battery systems. The "smartgrid" installation includes thermal-imaging technology that can detect potential issues by sensing unusual temperature variations in a piece of equipment.
The substation transforms 220,000-volt power from transmission lines into 13,000-volt power for distribution to larger customers and to neighborhoods. Peco said it was part of the utility's $500 million annual budget for infrastructure improvements and maintenance.
