New Hampshire: Measure consumption before attributing savings
Start with DOE FEMP: boiler purchasing, sizing and lifecycle analysis. 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.
Build the operating baseline
Record actual billing periods, estimated readings, operating hours and occupancy or production. Separate space heating from process and hot-water use where the available data permits. Explain changes before comparing periods.
Reconcile engineering and procurement
Have qualified personnel evaluate controls, equipment and service capacity. Update the contracted volume forecast after a project and review tolerance or minimum-volume terms. Verify program eligibility and preapproval before treating an incentive as funded.
New Hampshire utility application
| Gas service company | Contract component to revisit after load reduction | 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
After reducing forecast consumption, revisit Seasonal utility cost-of-gas alternative versus supplier gas, capacity and balancing. Ask whether the revised operating load changes Northern Utilities or EnergyNorth gas company, class and transport schedule or any conditions associated with Utility-active gas supplier, metering and effective service conditions.
Worked check: fixed charges do not fall with every therm
Assume hypothetical use of 10,000 therms at a constant $0.80 supply price and a $30 monthly supply fee. Modeled supply cost is $8,360. If use falls ten percent to 9,000 therms with the same price and fee, the total becomes $7,560: an $800 reduction, or about 9.57 percent of that supply total. This excludes delivery, taxes and project costs and proves no equipment result. The illustration shows why a percentage therm reduction is not automatically the same percentage dollar reduction.
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.
