Massachusetts Commercial Gas | Eligibility, Costs & Contract Guide

How the Massachusetts gas options differ

The DPU describes competitive suppliers and retail agents while noting that not every supplier serves every customer type and territory. Utility gas supply is compared with the applicable gas adjustment factor.

Verify supplier or retail-agent licensing and commercial service availability. Do not treat a license as proof of a quote for this meter.

Utility and commercial service map

This map covers the utility routes represented by our Massachusetts city guides. It is not an exhaustive statewide utility or supplier roster. A community or county listing does not confirm an individual service address.

Massachusetts competitive gas supply — 4 represented gas companies

Represented companies: Eversource Energy (NSTAR Gas); National Grid (Boston Gas); Eversource Energy (EGMA); Liberty Utilities.

Massachusetts DPU distinguishes competitive gas suppliers and retail agents and notes that service availability varies by company and customer type. The utility’s gas adjustment factor is an important comparison component. National Grid also publishes an authorized supplier route; Eversource and Liberty accounts need their own company’s enrollment requirements.

Cost scope: Applicable seasonal gas adjustment factor versus supplier supply and excluded delivery items. Operating question: Supplier/agent license, company participation and effective meter-read start.

Program Massachusetts; Nationalgrid Ma Choice. MassGIS: natural gas providers by Massachusetts municipality.

Territory and program exceptions to keep visible

MassGIS’s town-level gas record for Boston lists Eversource Energy (NSTAR Gas), National Grid (Boston Gas). This is a municipality record, not confirmation that a main reaches every property. Identify which listed company serves the meter before choosing a tariff or authorized supplier list. Boston source notes.

MassGIS’s town-level gas record for Fall River lists Liberty Utilities. This is a municipality record, not confirmation that a main reaches every property. Fall River source notes.

A practical Massachusetts account decision

Compare the applicable seasonal utility supply alternative with the same contract months. Ask what transportation and distribution items remain outside a fixed supply price.

Record the utility’s legal service company, commercial rate code, billed unit and supply arrangement in one account row. Keep a separate row for each meter even where a supplier offers one master agreement. Normalize gas units before entering rates; compare constant supply prices and fees only after the available service and cost scope are clear.
