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 is focused on achieving an 80 percent economy-wide reduction in overall New York City emissions (covering both City government operations and private sector) by 2050, using a Fiscal Year 2006 baseline for City government operations.
  2. 40x25 and 50x30, which are focused on achieving a 40 percent emissions reduction for City government operations by 2025 and 50 percent by 2030, using a Fiscal Year 2006 baseline. These new targets, put forth under the 2019 Climate Mobilization Act, are intended to accelerate progress towards 80x50.
  3. 100MWx25, which is focused on installing 100 megawatts of solar photovoltaic systems on City buildings by 2025.
  4. 100MWhx20, which is focused on installing 100 megawatt hours (“MWh”) of energy storage across private and public facilities by 2020.
  5. Executive Order 26 (“EO26”), which committed the City to the principles of the Paris Climate Agreement. As part of the planning associated with EO26, the City pledged to reduce energy usage from City buildings by a further 20 percent by 2025 from a Fiscal Year 2016 baseline.

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.
