Stuyvesant Town, Manhattan

Stuyvesant Town, Manhattan

Stuyvesant Town, commonly known as StuyTown, is one of the largest residential complexes in the United States. Located in Manhattan, it comprises 89 addresses, as well as playgrounds and parks. StuyTown’s management wanted to reduce energy bills and provide emergency power, a need driven by the experience of Superstorm Sandy in 2012.

As part of a detailed study in 2017, Ecosystem proposed a project designed to reduce the dependence on costly Con Edison steam. A plant will be constructed including two combined heat and power (CHP) units and three high-efficiency boilers.

The new installation will generate electricity for 42 addresses and heating for 12 addresses, reduce operating costs, and provide emergency power. Steam heating system optimization will also improve tenant comfort. GHG emissions will be reduced by 1,018 metric tons of CO2/year, positioning StuyTown as a leading participant in the NYC Mayoral Carbon Challenge. Project cost, annual savings, and incentives were guaranteed to mitigate risk and ensure StuyTown will successfully achieve a significant portion of its future sustainability goals with this project.
