Texas: 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 Texas. 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.

| Corpus Christi Gas | Municipal gas customer, delivery and supply charges | Official program / tariff |
| CenterPoint Energy Houston gas | Commercial sales gas-cost component versus supplier gas, transport and retained charges | Official program / tariff |
| CenterPoint Energy South Texas gas | Commercial sales gas-cost component versus supplier gas, transport and retained charges | Official program / tariff |
| CPS Energy | Utility sales alternative versus transport service and customer-owned gas costs | Official program / tariff |
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
After reducing forecast consumption, revisit Commercial sales gas-cost component versus supplier gas, transport and retained charges. Ask whether the revised operating load changes Gas operating division, incorporated/unincorporated jurisdiction and commercial class or any conditions associated with Transportation agreement, capacity, balancing and the utility’s accepted supplier arrangements.
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 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.
