Susquehanna-Roseland Power Line, A $1.4 Billion Project, Switched On

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.

When an explosion Wednesday morning caused operators to cut power to one of two nuclear reactors at the Limerick Generating Station, it had an impact on the power supply to the entire mid-Atlantic region.

One of two reactors was shut down at 8:39 after an electrical problem caused by an explosion in a transformer cut power to a turbine cooling system, officials said.

And, while only a portion of Berks County lies within the 10-mile emergency zone around the Montgomery County nuclear plant, losing just one unit affected some businesses throughout Berks and the region, said Ray Dotter, spokesman for the PJM Interconnection, the King of Prussia-based agency that regulates the regional electric supply.

Each Limerick reactor generates enough electricity to power 1 million homes. That power has to be made up somewhere, Dotter said.

Allentown, PA based PPL Electric set a record for morning peak power consumption today between 7 a.m. and 8 a.m.  Record cold temperatures were the reason.  The company released preliminary numbers showing that 7,432 megawatts were delivered.  The previous record was set on February 11, 2008 when 7,163 megawatts were delivered for the same time period between 7 a.m. to 8 a.m.

PPL Electric’s all-time peak record was set for the 6 p.m. to 7 p.m. period on February 5, 2007, when 7,557 megawatts were delivered.

For a point of reference:

A standard household light bulb has a power rating of between 25 and 100 watts. 

A kilowatt is equal to 1,000 watts.  The average electrical energy consumption in the United States is 8,900 kilowatts a year, per household.  Your electric bill reflects your usage in kilowatt hours.

One megawatt of electricity is equal to 1,000,000 watts.

PPL is just one of 11 electricity suppliers in Pennsylvania!
