Connecticut: 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 Connecticut. 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.
Connecticut utility application
| Gas service company | Contract component to revisit after load reduction | Primary reference |
|---|---|---|
| Southern Connecticut Gas | Marketer supply, utility transportation and any metering or data charges | Official program / tariff |
| Yankee Gas / Eversource | Marketer supply, utility transportation and any metering or data charges | Official program / tariff |
| Connecticut Natural Gas | Marketer supply, utility transportation and any metering or data charges | Official program / tariff |
| Norwich Public Utilities | Municipal gas service and supply components | Official program / tariff |
Southern Connecticut Gas: the program detail behind this decision
PURA describes firm transportation for commercial and industrial customers. The state’s approved gas-marketer information and the actual distribution company’s active enrollment requirements answer different questions. The town roster identifies the gas distributor separately from interstate transmission pipelines. Program Connecticut.
Apply the evidence to an account file
After reducing forecast consumption, revisit Marketer supply, utility transportation and any metering or data charges. Ask whether the revised operating load changes Commercial or industrial class and the distribution company’s firm-transportation requirements or any conditions associated with PURA approval, utility-active marketer and accepted start date.
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 Connecticut 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.
