Maryland: 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 Maryland. 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.
Maryland utility application
| Gas service company | Evidence needed for the baseline | Primary reference |
|---|---|---|
| Baltimore Gas and Electric | Utility commodity alternative versus the supplier’s complete price and recurring charges | Official program / tariff |
| Chesapeake Utilities Maryland | Maryland customer charges, supply/transport and applicable adjustments | Official program / tariff |
| Washington Gas | Utility commodity alternative versus the supplier’s complete price and recurring charges | Official program / tariff |
| Columbia Gas of Maryland | Utility commodity alternative versus the supplier’s complete price and recurring charges | Official program / tariff |
| Easton Utilities | Purchased Gas Charge and the applicable municipal service charges | Official program / tariff |
| Washington Gas / BGE boundary review | Utility commodity alternative versus the supplier’s complete price and recurring charges | Official program / tariff |
Baltimore Gas and Electric: the program detail behind this decision
Maryland’s official gas-choice resource separates utility delivery from licensed supply and requires customer authorization for a switch. Compare a commercial offer with the appropriate utility supply component. An electric provider, a residential rate display or a PSC license alone does not establish enrollment for this gas meter. Program Maryland.
Apply the evidence to an account file
The case file needs comparable evidence for Utility commodity alternative versus the supplier’s complete price and recurring charges. First establish Gas distributor, commercial rate class and utility-registered supplier 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.
Read the Maryland utility guide for the wider service-company distinctions. Convert billed gas units using the bill’s heat-content factor when moving from volume to energy.
