Texas: Make the bid specification match the utility
Start with EIA: natural gas customer choice and eligibility. The table below links this decision to the represented gas companies in Texas. It does not establish service or supplier availability for every account.
Require an inclusion schedule
Ask bidders to mark commodity, capacity, balancing, taxes, utility transportation and account fees as included, excluded or variable. An unanswered field is an unresolved cost, not zero.
Compare risk as well as the modeled total
Read the volume measurement period, assignment process, early-exit calculation and renewal mechanism. Request a written calculation for a material overrun or closure rather than relying on a product name such as fixed or flexible.

Atmos Energy West Texas: the program detail behind this decision
Texas electricity shopping rules do not establish natural-gas supplier choice. Gas service depends on the distributor, rate jurisdiction and tariff. A transportation arrangement must be qualified for the account; compare it with the actual utility commercial sales alternative and account for the remaining delivery obligations. Program Texas; Texas Rrc Tariffs.
Apply the evidence to an account file
Give bidders the same specification for Commercial sales gas-cost component versus supplier gas, transport and retained charges. Ask who is responsible for Transportation agreement, capacity, balancing and the utility’s accepted supplier arrangements. Do not rank an incomplete answer as the cheapest complete offer.
Worked check: fees can reverse the lower rate
Assume hypothetical annual consumption of 10,000 therms. A costs $0.80 per therm plus $20 monthly: $8,240. B costs $0.76 plus $60 monthly: $8,320. B’s commodity price is lower, but its modeled supply total is $80 higher. Equal cost occurs at 12,000 annual therms under these constant-rate assumptions. These are invented inputs, not available offers, local tariffs or program thresholds. Delivery, tax, exit costs and any excluded components still require a separate review.
Turn the review into a calculation
Compare constant supply rates and fees. 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 Texas 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.
