Switching Massachusetts Energy Suppliers
After passing the Electric Industry Restructuring Act in 1997, Massachusetts residents were introduced to a competitive energy marketplace. This made Massachusetts one of the 30 energy choice states in the country.
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 plans to fit your budget. For example, Constellation offers:
no sign-up fees,
exceptional customer service,
and a variety of fixed-rate natural gas and electric plans.
Understanding Energy Suppliers vs. Utilities
Utilities 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, which send energy to you to power your home or business.
What is an energy supplier?
Suppliers set the rate you pay for energy and source where your energy comes from, which may give you more control over your budget and your energy options. Energy suppliers can also offer fixed-rate plans, so you know what rate you pay every month.
Constellation is an energy supplier in Massachusetts; this means that we aren't the utility company that powers your home, but the one who sets your rate and contract term. As your energy supplier, we provide you with customized plans, competitive natural gas and electric rates, and exceptional customer service!
