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 Pennsylvania 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
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 and gas pipelines which deliver energy to you to serve your home or business.
What is an energy supplier?
Energy suppliers let you pick and set the rate you pay for energy. The right to choose among Massachusetts energy suppliers gives you more control over your budget by providing you with more home energy options (for example, choosing a renewable electric plan). Massachusetts energy suppliers can also offer fixed-rate plans, so you know what energy rate you'll be paying every month, ahead of time.
Constellation is a natural gas and electricity supplier in Massachusetts, which means that we aren't the utility company that delivers electricity and natural gas to your home, but the one who sets your rate and contract term. As your Massachusetts energy supplier, we provide you with customized plans, competitive natural gas and electricity rates, and exceptional customer service!
