Energy Capital Partners has landed another extension deal at One World Trade Center tower in the Financial District.
The energy transition infrastructure investor has signed to occupy a total of 70,425 square feet at the 104-story building, which is the tallest in the Western Hemisphere. The deal will give Energy Capital full access to the 59th floor.
Newmark represented the tenant on the deal, with Durst Organization getting in-house support.
This marks Energy Capital's third expansion at the building that's owned through a joint venture between The Durst Organization and The Port Authority of New York and New Jersey. Originally, the company signed to take just 6,173 square feet at the site in 2017.
Murray Karp, managing partner and chief operating officer at Energy Capital, said that the expansions at the building come as the company grows and One World Trade's location, strong amenity package and innovation continue to match its needs.
Particularly, the property offers 25,000 square feet of amenity space on the 64th Floor Sky Lobby, which includes prepared meals, as well as event and lounging space.
"The World Trade Center continues to distinguish itself as the premier business address in the region, and Energy Capital Partners' decision to expand their presence here yet again is a clear signal of the value this campus delivers," Jolene Yeats, World Trade Center director at the Port Authority of New York and New Jersey, said in a statement.
"Across our campus, the combination of world-class office space, unrivaled transit connectivity, and the dynamic energy that comes with being an arts, culture and dining destination continues to attract and retain forward-looking organizations year after year."
Another major recent lease at One World Trade was Condé Nast signing for 192,000 square feet, as reported by the Commercial Observer in September 2025.
Some other tenants that operate inside the 3.1 million square feet building include Celonis, Stagwell, Scale AI, Frier Levitt, Nast Publications and Carta, Ameriprise.
