Match seasonal gas usage to contract pricing in Wyoming

EIA identifies weather, storage and demand as gas-price influences. This does not establish that every winter price will exceed every summer price. Match monthly usage with the price mechanism and service obligations that actually apply.

Wyoming: Build a month-by-month exposure map

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.

Use weighted prices

For each month, multiply projected therms by that month’s assumed supply price. Add applicable fixed fees separately. An unweighted average gives a low-volume summer month the same influence as a high-volume heating month.

Separate price exposure from operating exposure

A fixed commodity component does not establish firm transportation or remove a curtailment obligation. Ask operations to review notice and response requirements independently of finance’s price scenario.

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

In the monthly budget, keep Program-year supplier option and rollover terms, plus utility distribution costs visible. Obtain the service response for Correct division confirmation code and account-specific selection deadline before assuming that a winter price arrangement also guarantees the required operating flexibility.

Worked check: an average can hide the heating load

Assume a hypothetical two-month illustration uses 3,000 therms at $1.00 and 1,000 therms at $0.60. The commodity total is $3,600 and the usage-weighted price is $0.90 per therm. The simple average price is $0.80; applying it to 4,000 therms understates the illustration by $400. No fees or delivery charges are included. This is arithmetic, not a claim about which local months or prices will be higher. Use all twelve actual delivery months for the real budget.

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.

Sources and review notes

Reviewed October 16, 2026. Program information can change. Confirm the effective utility tariff, supplier availability and written offer before proceeding. Examples and planning tools are educational; they are not executable quotes or verified customer results.

A practical next step

Put the full contract in view.

Ask about your utility, supply terms or renewal. Keep account numbers and documents out of the initial inquiry.
