Carbon-Free Electric Program

HG&E is excited to offer a new program to help commercial and industrial customers reach 100% carbon-free electricity. While the carbon-free portion of HG&E’s overall power portfolio mix is currently among the highest in the region, there is still a need to purchase electricity from the New England Gridduring certain times throughout the year in order to meet the total customer demand.

For commercial and industrial customers electing to purchase all of their electricity from 100% carbon-free sources, HG&E will procure the supplemental carbon-free electricity required by purchasing and retiring MA Class I or Class II Renewable Energy Certificates (RECs). These costs will be passed along to the customer on-bill through a newly created rate component associated with their electricity usage.


HG&E has set incremental targets to reach net-zero energy by 2050, but we understand some customers would like to take personal action and be carbon-free today. Program participants will receive carbon-free electricity marketing materials including: a carbon-free logo, print indicia, and webpage materials. In addition, HG&E will provide a letter at the end of the program year indicating the organization's carbon-free electric status.
