In compliance with the terms and conditions, Eversource is providing the hourly load shapes for various customer classes which are used to estimate these supplier loads.

To download the average hourly data for a specific customer class, select the MS Excel file format and save the file to your hard drive. Once the file is saved, it can be imported into most spreadsheet programs.
