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 gas 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.

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!
