New York: Find which cost can actually change
Start with EIA: natural gas volume, heat content and energy units. The table below links this decision to the represented gas companies in New York. It does not establish service or supplier availability for every account.
Use five separate checks
Check the billed class; reconcile readings and corrections; identify supply versus delivery; count recurring account fees; and update the consumption forecast for operational changes. Keep each proposed action tied to the charge it can affect.
Avoid counting a reduction twice
Model an equipment project at the revised gas volume before comparing supplier offers. A fixed monthly charge remains even when therms fall. Keep equipment investment, supply cost and retained utility costs in separate budget lines.
New York utility application
| Gas service company | Cost component to investigate | Primary reference |
|---|---|---|
| National Grid | Utility supply alternative versus ESCO price definition, fees and retained delivery | Official program / tariff |
| NYSEG | Utility supply alternative versus ESCO price definition, fees and retained delivery | Official program / tariff |
| National Fuel Gas Distribution / Reserve Gas | Utility supply alternative versus ESCO price definition, fees and retained delivery | Official program / tariff |
| Con Edison | Utility supply alternative versus ESCO price definition, fees and retained delivery | Official program / tariff |
| Con Edison / National Grid | Utility supply alternative versus ESCO price definition, fees and retained delivery | Official program / tariff |
| National Fuel Gas Distribution | Utility supply alternative versus ESCO price definition, fees and retained delivery | Official program / tariff |
| Rochester Gas & Electric | Utility supply alternative versus ESCO price definition, fees and retained delivery | Official program / tariff |
| Orange & Rockland | Utility supply alternative versus ESCO price definition, fees and retained delivery | Official program / tariff |
National Grid: the program detail behind this decision
New York DPS explains how to shop for an energy service company while utility delivery continues. The service territory, commodity and customer class must all match. A municipal electric provider or the residential Power to Choose display is not an executable commercial gas bid. Program New York.
Apply the evidence to an account file
For this account, investigate Utility supply alternative versus ESCO price definition, fees and retained delivery. If the proposed action changes only the supply component, retain the other components when calculating the total bill effect.
Worked check: price and volume are different effects
Assume purely hypothetical comparable commodity use falls from 10,000 to 9,000 therms while its price rises from $0.80 to $0.85 per therm. Commodity cost changes from $8,000 to $7,650. At the original price, lower volume explains negative $800; the price change on actual use adds $450. The net difference is negative $350. Fixed charges, delivery, taxes and other costs are excluded. It would be incorrect to report that entire $350 as a supplier-price saving.
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 New York 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.
