Energy Management


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

  1. 80x50, a carbon reduction goal to reduce 80 percent of New York City’s overall emissions, for City government operations and the private sector, by 2050 (using Fiscal Year 2006 as the baseline for City government operations).
  2. 40x25 and 50x30, carbon reduction goals to reduce 40 percent emissions for City government operations by 2025 and 50 percent by 2030, as steps toward 80x50.
  3. 100MWx25, a goal to install 100 megawatts of solar photovoltaic systems on City buildings by 2025.
  4. 100MWhx20, a goal to install 100 megawatt hours (MWh) of energy storage across private and public facilities by 2020.
  5. Executive Order 26, which committed the City to the principles of the Paris Climate Agreement and reducing energy usage from City buildings by 20 percent by 2025 (using Fiscal Year 2016 as the baseline).

Did You Know?

The Solar Energy Industries Association (a U.S. trade association) calculates that on average one megawatt of solar power generates enough electricity to meet the needs of 164 U.S. homes. 100 megawatts of solar power is thus enough, on average, to power 16,400 U.S. homes.

A megawatt can power…

  • Power the average American home for 1.2 months
  • Drive an electric vehicle 3,600 miles
  • Power two 60-watt lightbulbs non-stop for a year
  • Smelt 137 pounds of aluminum
  • Toast 89,000 slices of bread
  • Run an average home pool pump for 5 months
  • Run two modern refrigerators for a year

In 2015 in New York City, public and private buildings represented 67% of citywide emissions. This means that reducing emissions from buildings is critical to reaching 80x50, and the City is committed to leading the way with its own buildings. The City focuses on six major areas for energy management:

  • energy supply
  • clean energy generation
  • demand response and load management
  • energy efficient operations and maintenance
  • energy efficiency retrofit projects
  • energy training and innovation
