EPA Portfolio Manager - Massachusetts Gas

National Grid supports the EPA’s Portfolio Manager tool for Massachusetts Gas 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 select the property type below that applies to you and follow the steps accordingly.

Step 1: 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: You must print, fill out and submit the Energy Usage Release Form* for each tenant. Email the completed form in a PDF format to NE.EnergyEfficiency@nationalgrid.com.

NOTE: Municipalities or governmental agencies that have multiple properties that they would like data for can submit via email a signed Energy Usage Release Form with an Excel or Word file that lists all the managed buildings with their corresponding National Grid account information.  Only one (1) account number per building is required.

Step 3: 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 quarterly building usage information for up to four (4) years, as long as building owners maintain their EPA Portfolio Manager web share link as active.  Deactivating EPA portfolio manager property share link will disable the upload process.

We have enhanced our system by providing customers the option to obtain two (2) additional years of aggregated whole-building usage data, after the initial data upload is completed.

If you have already completed the initial data load process using the steps and link outlined above, fill out the Additional historical usage data upload online form to receive two(2) additional years of prior aggregate usage information.

This additional data will take up to 7 business days to get uploaded into your portfolio manager account.

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  NE.EnergyEfficiency@nationalgrid.com or call (855) 563-7448, 8:00 am to 5:00 pm EST Monday through Friday.

*The Energy Usage Release Form gives National Grid permission to disclose aggregate energy data to EPA Portfolio Manager.
