New Hampshire: Budget the exposed components rather than one future rate
Start with EIA: supply, demand, weather and storage price drivers. The table below links this decision to the represented gas companies in New Hampshire. It does not establish service or supplier availability for every account.
Create a scenario register
Keep monthly usage, index assumptions, location differential, fixed charges and exposed adjustments in separate columns. Name the source and observation date for market data. A supplier’s written formula determines how an observation reaches the bill.
Use a revision trigger
Set an internal review date and identify operational changes that justify a new budget: closure, added shifts, equipment replacement or a corrected baseline. Keep a downside scenario visible without presenting it as a prediction or creating unsupported urgency.
New Hampshire utility application
| Gas service company | Component requiring a separate forecast | Primary reference |
|---|---|---|
| Liberty Utilities / EnergyNorth | Seasonal utility cost-of-gas alternative versus supplier gas, capacity and balancing | Official program / tariff |
| Unitil / Northern Utilities | Seasonal utility cost-of-gas alternative versus supplier gas, capacity and balancing | Official program / tariff |
| Liberty Utilities Keene service | Actual billed therms, customer charge and applicable cost-of-gas component | Official program / tariff |
Liberty Utilities / EnergyNorth: the program detail behind this decision
Gas transportation in New Hampshire follows the gas company’s tariff. Unitil’s electricity towns are not its gas towns, and Liberty’s service-area page flags very small coverage in Derry. A competitive electricity registration or electricity aggregation offer does not establish gas enrollment. Liberty Nh Current Tariff; Unitil Thirdparty.
Apply the evidence to an account file
Give Seasonal utility cost-of-gas alternative versus supplier gas, capacity and balancing its own documented model assumptions. Validate Northern Utilities or EnergyNorth gas company, class and transport schedule before using a utility comparison component; a forecast for a different class is not this meter’s available alternative.
An assumption register that can be updated without rewriting history
Record each month’s therms, price mechanism, assumed benchmark, location/service adders, recurring fees and retained utility charges. Keep the original budget alongside revisions and actuals. Change one driver at a time to identify sensitivity, then test a combined adverse scenario. For a fixed commodity offer, leave that defined component fixed over its contractual months while varying usage and genuinely exposed items. Do not apply a current spot observation to every future month or label an invented scenario as the forecast available to the customer.
Turn the review into a calculation
Build a monthly weighted budget. 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 Hampshire 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.
