Constellation is limiting the terms of its natural gas supply contracts in Massachusetts. Based on current market conditions, we expect to exit the natural gas supply business in Massachusetts effective Oct. 31, 2023.

What will change for natural gas customers in Massachusetts?

Constellation will notify you by mail of the date when we will no longer be able to service your natural gas supply and will be returning you to your utility for service.

Will Massachusetts power customers be impacted?

No, there are no changes to power contracts in this market. The change is solely for natural gas contracts.

Are there any exceptions?

We do not anticipate there being any.  Customers whose contracts extend beyond Oct. 31,2023 will be contacted directly.
