The long-anticipated Susquehanna-Roseland power line was fully energized this week for the first time.
The 150-mile-long, 500-kilovolt line links PPL Electric Utilities’s switchyard at its Susquehanna nuclear power plant in Salem Township, Luzerne County, Pennsylvania, to Public Service Enterprise Group Inc.’s switching station in Roseland, Essex County, New Jersey.
It cost $1.4 billion and is designed to bolster electricity reliability for the power grid run by Pennsylvania-based PJM Interconnection that serves 61 million people in all or parts of 13 states plus the District of Columbia.
“It’s all about reliability,” PPL Electric Utilities spokesman Paul Wirth said. “It prevents overloads on other power lines and gives electricity another path to travel, especially during period periods when it’s extremely hot or extremely cold.
