To provide a range of City services to residents, businesses, commuters, and visitors, New York City’s government uses large amounts of energy each year. For City buildings and other stationary end uses, the major energy types are electricity, natural gas, steam, and fuel oil. Today, DEM is responsible for developing and administering the $750+ million Heat, Light, and Power Budget, which covers energy expenses for City buildings and other stationary end uses. Within the City buildings portfolio, school buildings consume the largest amount of energy, followed by City government buildings, wastewater treatment plants, hospitals and senior colleges. Cultural institutions, jails, street lighting, agency office space, and libraries account for the rest of energy consumption.
DEM handles meter and account management for all City buildings where the City pays all or part of the utility energy costs. DEM opens and closes accounts with utilities on behalf of agencies.
DEM works with the City’s Office of Management and Budget to develop the City’s Heat, Light, and Power Budget, which covers electricity, natural gas, and steam each year. For Fiscal Year 2021, Heat, Light, and Power expenditures are expected to be $777 million, with the City-funded portion $714.7 million. Electricity represents over three-quarters of the budget in terms of total cost, and almost half of the budget in terms of total energy usage. Natural gas for heating is 16.0% of cost and 47.9% of usage, while steam makes up the balance. The City handles budgeting for fuel oil purchases separately.
DEM works with City agencies to monitor their energy billing and confirm that the utility energy bills received for their buildings are correct and reflect their actual energy usage. We maintain a web-based reporting system that provides agencies with energy billing data in a variety of formats to help them identify opportunities to save energy and reduce emissions. Reports are available at citywide, agency, account, and meter levels.
