Description Headquartered in Westborough, Massachusetts, Columbia Gas of Massachusetts delivers clean, affordable and efficient natural gas to more than 310,000 natural gas customers in southeastern Massachusetts, the greater Springfield area and the Merrimack Valley.
Columbia Gas of Massachusetts continues to grow as more businesses and homeowners convert from oil and electricity to natural gas. Today, natural gas satisfies 24 percent of our nation's total energy demand and only 18 percent of New England's energy demand. The region's under-saturated natural gas market means growth opportunities for natural gas companies, which are unparalleled in most other areas of the country.
