MORRISTOWN, N.J., Nov. 14, 2016 /PRNewswire/ -- As part of ongoing efforts to modernize its electric system, Jersey Central Power & Light (JCP&L) has installed new state-of-the-art equipment at a substation in East Windsor that will help enhance service reliability for several thousand customers in the Mercer County area. The $500,000 project included installing a massive 5-ton, 15-foot tall circuit breaker, a disconnection switch and other equipment. With lower maintenance costs and enhanced operability in hot and cold weather, the new gas-filled breakers are an upgrade from the previous oil-filled equipment. Circuit breakers in substations are protective devices designed to "break" the flow of electricity from one electrical circuit to another. "The new breakers provide additional protection for the substation and allows circuits to be switched quickly should an interruption occur," said Anthony Hurley, JCP&L vice president of Operations. "The project strengthens the transmission system and supports the distribution and delivery of electricity to Mercer County residents and businesses." This project is part of JCP&L's previously announced $387 million infrastructure investment in 2016 and is one of several included in JCP&L's "Energizing the Future" initiative to expand and enhance its transmission system in northern and central New Jersey to provide better service reliability for customers. JCP&L is a subsidiary of FirstEnergy Corp. (NYSE: FE). JCP&L serves 1.1 million customers in the counties of Burlington, Essex, Hunterdon, Mercer, Middlesex, Monmouth, Morris, Ocean, Passaic, Somerset, Sussex, Union and Warren.
