Switching Massachusetts Energy Suppliers

In Massachusetts, utility companies used to be the only option for energy users — the utility controlled delivery, pricing and maintenance. After passing the Electric Industry Restructuring Act in 1997, Massachusetts residents were introduced to a competitive energy marketplace, letting you choose the best Massachusetts energy supplier for your needs.

What does energy choice mean? 

Energy suppliers in Massachusetts compete for your business, which can result in reduced energy costs, better customer service, more innovative energy solutions, and energy plans to fit your budget. For example, Constellation offers natural gas and electricity plans to Massachusetts residents with:

  • no sign-up fees, 
  • exceptional customer service, 
  • and a variety of fixed-rate electric and natural gas plans.

Understanding Energy Suppliers in Massachusetts vs. Utility Companies

Utility companies deliver natural gas and electricity to your home. In Massachusetts, this means your utility — which many customers refer to as light and power companies — owns the power lines and gas pipelines which deliver energy to you to serve your home or business. Energy suppliers, like Constellation, let you pick and set the rate you pay for energy. As your Massachusetts energy supplier, we provide you with customized plans, competitive natural gas and electricity rates, and exceptional customer service!
