Kentucky: 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 Kentucky. 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.
Kentucky utility application
| Gas service company | Seasonal cost and service exposure | Primary reference |
|---|---|---|
| Columbia Gas of Kentucky | Choice enrollment, current supplier participation and return conditions | Official program / tariff |
| Atmos Energy Kentucky | Firm/interruptible obligations, pool operator and accepted transportation agreement | Official program / tariff |
| Duke Energy Kentucky | Current Kentucky tariff, approved arrangement and start date | Official program / tariff |
| Louisville Gas and Electric | Firm capacity, pool responsibility and the applicable service agreement | Official program / tariff |
| Henderson Municipal Gas | HMG confirmation of the requested pricing or transportation arrangement | Official program / tariff |
| City of Murray Natural Gas | Account-specific commercial options and utility acceptance | Official program / tariff |
| Delta Natural Gas | Delta qualification, delivery point and required agreement | Official program / tariff |
Columbia Gas of Kentucky: the program detail behind this decision
Kentucky PSC publishes Columbia Customer Choice information. Columbia’s territory and class requirements matter: the program is not a statewide enrollment path for Atmos, Duke, LG&E, Delta or municipal accounts. Keep the bill’s Mcf units and its heat-content conversion visible when comparing a per-therm offer. Program Kentucky; Columbia Ky Current Tariff.
Apply the evidence to an account file
In the monthly budget, keep Utility gas cost versus supplier supply, with Mcf and therms reconciled visible. Obtain the service response for Choice enrollment, current supplier participation and return conditions 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 Kentucky 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.
