Energy Management


The Department of Citywide Administrative Services (DCAS) Division of Energy Management (DEM) is the hub for energy management in City buildings. As such, we play a critical role in supporting our agency partners' progress towards the City's major emissions reduction and energy objectives. These goals include the following:

  1. 80x50, which focuses on achieving an 80% economy-wide reduction in overall New York City emissions (both City government operations and private sector) by 2050 from an FY2006 baseline.
  2. 35x25, which focuses on achieving a 25% emissions reduction from City buildings by 2025 from a CY2005 baseline.
  3. 100MWx25, which focuses on installing 100 megawatts of solar photovoltaic (PV) on City buildings by 2025.
  4. 100MWhx20, which focuses on installing 100 megawatt hours of energy storage at both private and public facilities by 2020.

Since public and private buildings represented 67% of citywide emissions in 2015, reducing emissions from buildings is critical to reaching 80x50. The City has committed to leading the way in our own buildings.

DEM derives our authority from DCAS's City Charter responsibility to handle utility matters for the City. Today, we focus our work in six major areas, namely, the City's energy supply, clean energy generation, demand response and load management, energy-efficient operations and maintenance, energy efficiency retrofit projects, and energy training and innovation.
