Wyoming: 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 Wyoming. 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.
Wyoming utility application
| Gas service company | Contract component to revisit after load reduction | Primary reference |
|---|---|---|
| Black Hills Wyoming Gas | Program-year supplier option and rollover terms, plus utility distribution costs | Official program / tariff |
| Black Hills Wyoming Gas | Division-specific sales gas cost or qualified transportation costs | Official program / tariff |
| Enbridge Gas Wyoming | Applicable sales gas cost versus transport, retained gas and supplier charges | Official program / tariff |
| Montana-Dakota Utilities | Purchased-gas adjustment under sales versus transportation and retained gas obligations | Official program / tariff |
| Wyoming Gas Company | Company gas-supply and service components | Official program / tariff |
Black Hills Wyoming Gas: the program detail behind this decision
Black Hills’ Wyoming Choice Gas town list separates Casper, Gillette and Torrington divisions and explains that prices or confirmation codes may differ by division. Cheyenne, Cody and other utilities’ towns must not be added merely because they are in Wyoming. Use the account’s selection packet and next applicable window. Wy Choice; Bh Wy Choice Towns.
Apply the evidence to an account file
After reducing forecast consumption, revisit Program-year supplier option and rollover terms, plus utility distribution costs. Ask whether the revised operating load changes Participating town, Choice Gas division and account selection packet or any conditions associated with Correct division confirmation code and account-specific selection deadline.
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 Wyoming 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.
