SEWAREN - New Jersey's largest utility is touting a new power plant being built at a facility severely damaged by Superstorm Sandy.

Gov. Chris Christie and New Jesey Senate President Steve Sweeney were among those taking part in a ceremonial groundbreaking Tuesday at PSE&G's Sewaren complex.

The switching station located on the property was knocked off when the storm hit in October 2012.

“Nothing will ever be perfect, and there will always be times when we’re challenged by Mother Nature, but we learned an extraordinary amount 3 1/2 years ago,” says Christie.

PSE&G has since spent about $125 million to upgrade and reinforce the station. The projects are part of its $1.2 billion infrastructure investment to protect and strengthen its electric and gas systems against severe weather.

The new 540-megawatt plant will replace the 65-year-old power plant and will be known as Sewaren 7.

Sen. Sweeney says that the new, more energy-efficient power plant will help to draw new businesses to the area.

“Businesses aren't going to come to places where you have 75-year-old power plants,” he says.

Gov. Christie declared New Jersey "rebuilt,” with "almost all" Sandy-affected residents back in their homes.
