Constellation Completes $7.9M Energy Efficiency Project Across World Trade Center Campus

LED lighting and lighting controls upgrades expected to help Port Authority of New York and New Jersey reduce carbon emissions by more than 4,500 metric tons annually

NEW YORK (November 11, 2020) —  Constellation, an Exelon company, has finished retrofitting more than 13,000 lighting fixtures to new LED fixtures at the World Trade Center campus through a $7.9 million energy savings contract with the Port Authority of New York and New Jersey.

The improvements are expected to help the Port Authority conserve roughly 6.4 million kilowatt hours of electricity and reduce carbon emissions by more than 4,500 metric tons annually, the equivalent of taking nearly 1,000 passenger vehicles off the road, according to U.S. Environmental Protection Agency estimates. The Port Authority is expected to save more than $700,000 in the first year with continued annual savings over the term of a 10-year contact.    

Constellation upgraded more than 13,000 lighting fixtures to high-efficient LED technology, which reduces energy consumption and increases the life expectancy of the lamps. World Trade Center’s Vehicle Security Center, Central Chiller Plant, WTC PATH Station, and Oculus Transportation Hub and back of house spaces are among the areas where improvements were made.    

Additionally, the “up lighting” in the Oculus, located between columns in the 800,000 square-foot facility, has been replaced with new red-green-blue spot lighting. Constellation installed lighting controls that will make is possible for WTC staff to display any desired color at their discretion. On Tuesday, November 10, the Port Authority announced the Oculus would be lit red, white, and blue in honor of Veteran’s Day, a first for the landmark building.

“The completion of this lighting project with Constellation is an important component of our efforts to increase energy efficiency at our facilities and we were especially excited to debut our new red, white, and blue Oculus lights in honor of America’s veterans," said Rick Cotton, Executive Director of the Port Authority of New York and New Jersey. "Through our partnership with Constellation we are making the World Trade Center campus more sustainable and resilient with the replacement of 13,000 lights to LED lighting fixtures, which will reduce both carbon emissions and the agency’s expenses."

 “This efficiency project will enable the Port Authority to save money and reduce its carbon footprint while also providing new vibrant display lighting in the Oculus,” said Mark Huston, President of Constellation’s National Retail Business. “We’re proud to help the Port Authority achieve its long-term sustainability goals while delivering solutions that improve the occupant experience for the commuters and visitors that frequent the World Trade Center every day.”

The Port Authority’s far-reaching sustainability agenda includes innovative and industry-leading strategies to advance its commitment to achieving a 35-percent reduction in greenhouse gases by 2025 and 80 percent by 2050 as outlined in the agency’s 2018 commitment to the Paris Climate Agreement. 

The project was implemented through the Port Authority’s Guaranteed Energy Savings Program. The program provides agency-wide resources to identify, develop and implement energy efficiency and clean energy opportunities that effectively contribute to Port Authority’s greenhouse gas emissions reduction goals.
