Energy and Water Data

The NYC Benchmarking Law requires building owners to report data on annual energy and water usage. Click on the section titles below to review how to obtain both types of data.

Energy Data
Water Data

Energy Data
In order to obtain whole building energy consumption data for benchmarking, building owners will need to obtain residential or non-residential tenant consumption data in addition to their base building data. If your property(ies) is/are not master-metered or you do not have whole building energy consumption data, the way to acquire this information is to request it from utility companies.

Automated Upload of Aggregated Energy Data
A building owner can obtain aggregated energy data (a building's entire electric and gas consumption measured by month) from a private utility. Both Con Edison and National Grid offer automated upload of aggregated consumption data.

IMPORTANT NOTE: If you benchmarked this property in previous years and created meters in Portfolio Manager for data received from Con Edison or National Grid, you should mark all of those meters as Inactive as of the start date of the first meter entry with a “To Date” in 2017. For example, if you have a meter with an entry with a start date of 12/15/2016 and end date of 1/15/2017, you should mark the meter inactive effective 12/15/2016.

Con Edison and National Grid will be automatically creating new meters. By deactivating old meters, you will avoid errors and double-counted data.

Consolidated Edison, Inc. (Con Edison)

  • Beginning in 2018, Con Edison will automatically upload your aggregated energy use
  • You must authorize release of data, associate Con Edison service addresses with Portfolio Manager property IDs, and request data uploads on the Con Edison portal, in addition to connecting with Con Edison and sharing your property in Portfolio Manager.
  • Complete instructions and a link to the portal can be found here.

National Grid

  • The basic procedure for having aggregated data uploaded from National Grid requires you to establish National Grid as a contact, share the property (Full Access and Exchange Data), and then register on their website.
  • Instructions for connecting and collecting data from National Grid can be found here.
  • Please note that when sharing a property with National Grid, the address indicated in the “Basic Info” block under “Details” in Portfolio Manager must match a National Grid service address for that property.

Collecting Aggregated Energy Data for Manual Entry
A building owner can obtain aggregated energy data (a building's entire electric and gas consumption measured by month) from a private utility. For customers who are PSEG customers, PSEG offers aggregated consumption data:

PSEG Long Island (PSEGLI)

  • In order to guarantee that you receive your aggregated consumption data in time to meet the May 1 deadline, PSEG advises you to submit your request no later than Sunday, April 1, 2018.
  • Download the 2018 instructions and authorization form (in PDF), sign, and submit to PSEG Long Island.

Non-Residential Tenant Data Collection Form
Since January 2014, the Mayor's Office of Sustainability no longer requires building owners to issue a data collection request form to non-residential tenants. Building owners are strongly encouraged to request aggregated data directly from the utility companies.

Other Energy Sources
If your property uses energy not provided by National Grid or Con Edison, you must collect the use data from bills or directly from the provider. For example, if your building uses fuel oil, you must collect records of all deliveries from the previous year, create a meter in Portfolio Manager under the Energy tab, and manually enter the date and number of gallons for each delivery. Please note that when creating a meter for fuel oil, be sure that the “Enter as Delivery” button is switched on.

Water Data

Department of Environmental Protection (DEP)

The Department of Environmental Protection (DEP), manages New York City’s water supply and wastewater treatment, and provides all water consumption information to properties eligible and covered under the NYC Benchmarking Law. Only covered properties that have had an Automatic Meter Reader (AMR) installed for at least the entire previous calendar year will be required to benchmark their water consumption.

Building owners that benchmarked their data prior to 2018 by registering in Portfolio Manager® for automatic DEP water consumption data uploading do not need to re-register again this year. Water consumption data for those properties will be automatically uploaded for every year moving forward. Please note that data is uploaded in cubic feet.

If your property has not yet been shared with DEP to collect water data and is in the Covered Buildings List, log into Portfolio Manager® and share your property information with DEP.

  • Please read the instructions (in PDF) for how to get automated water data from DEP.
  • If your property is not eligible for automated water benchmarking, you have the option to benchmark water data manually. Please read the instructions (in PDF) for how to get manual water data from DEP.
  • Common web services errors are listed here.

All inquiries about water benchmarking should be directed to the Department of Environmental Protection at
