Wyoming: 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 Wyoming. 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.
Wyoming utility application

|---|---|---|
| Black Hills Wyoming Gas | Program-year supplier option and rollover terms, plus utility distribution 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
Give Program-year supplier option and rollover terms, plus utility distribution costs its own documented model assumptions. Validate Participating town, Choice Gas division and account selection packet 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 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.
