EPA Portfolio Manager - Metro NY

National Grid supports the EPA’s Portfolio Manager tool for Metro NY properties as part of a larger effort to promote energy efficiency and identify improvement opportunities for our customers. Portfolio Manager provides benchmarks to help customers assess the energy performance of their building(s), and encourage action to make the building(s) more efficient in a sustainable way. To accomplish this, National Grid must disclose the aggregated energy consumption data for your premises.

Please follow the steps below:

Step 1: In order to start the aggregate data upload process, you must visit the EPA Portfolio Manager site to register your property and complete the SHARE PROPERTY procedure. (If you haven't done so already.)
Step 2: Once you have completed the property share procedure with the EPA portfolio manager, select EPA Portfolio Manager Online Form link to complete the online register process with National Grid.
National Grid has implemented a quarterly aggregate data upload process that will continue to provide customers with their building usage information for up to four (4) years as long as building owner maintains their EPA Portfolio Manager web share link as active.

For more information on the process of uploading whole building aggregate data to Portfolio Manager, see our User Guide (PDF).

If you have any questions about the submission process, email National Grid at or call (855) 563-7448, 8:00 am to 5:00 pm EST Monday through Friday.
