Worked commercial gas cost examples in Massachusetts

Massachusetts: Build an auditable result instead of a sales story

Start with EIA: natural gas volume, heat content and energy units. The table below links this decision to the represented gas companies in Massachusetts. It does not establish service or supplier availability for every account.

Define the counterfactual

Retain what the business would otherwise have paid for the same service months and quantities. Identify whether that is an existing contract, an effective utility supply component or another dated written offer. Do not switch baselines after seeing the result.

Bridge model to invoices

Separate quantity changes from comparable price changes, then reconcile fixed charges, retained delivery and timing corrections. Preserve enrollment confirmation and invoices before presenting an actual outcome. A favorable calculator scenario is only a model.

Massachusetts utility application

Eversource Energy (NSTAR Gas): the program detail behind this decision

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. Program Massachusetts; Nationalgrid Ma Choice.

Apply the evidence to an account file

The case file needs comparable evidence for Applicable seasonal gas adjustment factor versus supplier supply and excluded delivery items. First establish Gas company legal entity, commercial class and authorized supplier availability so the proposed baseline is an available alternative for this account.

Worked case: distinguish a model from an observed result

For a hypothetical 10,000-therm account, $0.80 per therm plus $20 monthly models to $8,240. An alternative at $0.76 plus $60 monthly models to $8,320. That is an $80 increase in the defined supply scope, not a saving. This conclusion is still only a scenario until eligibility, accepted enrollment and actual comparable invoices are established. Keep the same quantity and delivery period in both calculations. Do not present these invented inputs as a local client case or publish them as market rates.

Turn the review into a calculation

Compare constant supply rates and fees. Enter documented assumptions in matching energy units. Keep any charge outside both supply offers separate; the result does not establish eligibility or an available quote.
