Natural gas is the right business choice for a clean, safe, and affordable future. It's not only one of the most efficient, environmentally friendly energy sources available today, it ensures convenient, worry-free, and year-round comfort for your business.  The benefits are numerous.

Gas Purchasing Options

All of our commercial and industrial natural gas customers may choose the company that supplies their natural gas – an option often referred to as customer choice. When a customer chooses to purchase their gas from another supplier, they still receive transportation service from Unitil.  A customer who does not wish to purchase their natural gas service from a supplier, or who cannot find an attractive supply alternative, automatically receives natural gas supply and transportation service from Unitil.
