Pennsylvania: 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 Pennsylvania. 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.
Pennsylvania utility application
| Gas service company | Evidence needed for the baseline | Primary reference |
|---|---|---|
| UGI Utilities | Applicable utility Price to Compare versus supply, fees and delivery exclusions | Official program / tariff |
| Peoples Natural Gas | Account-appropriate utility comparison component versus full supplier terms | Official program / tariff |
| PECO Gas | Account-appropriate utility comparison component versus full supplier terms | Official program / tariff |
| National Fuel Gas Distribution | Account-appropriate utility comparison component versus full supplier terms | Official program / tariff |
| Columbia Gas of Pennsylvania | Account-appropriate utility comparison component versus full supplier terms | Official program / tariff |
| Philadelphia Gas Works | Utility supply alternative, supplier charges and retained PGW delivery items | Official program / tariff |
UGI Utilities: the program detail behind this decision
UGI organizes gas municipalities into supply regions and publishes a supplier directory. Its gas coverage differs from its much smaller electric territory. Identify the gas supply region and class, then confirm that a listed supplier accepts that commercial account and offers terms for the desired period. Ugi Supply Regions; Ugi Suppliers.
Apply the evidence to an account file
The case file needs comparable evidence for Applicable utility Price to Compare versus supply, fees and delivery exclusions. First establish UGI gas class, supply region and participating 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 Pennsylvania 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.
