How natural gas supplier choice works

Separate the molecule purchase from delivery

A gas marketer procures gas and arranges upstream delivery under the applicable program. The local distribution company, often called the LDC, maintains the local pipeline network, reads the meter, and bills delivery service. Utility transportation charges do not disappear because a marketer provides supply. EIA emphasizes that programs vary substantially by service territory and customer category. A commercial facility should verify its own tariff and program rather than infer availability from residential advertising.

Understand nomination and balancing exposure

Gas use varies daily, especially at weather-sensitive buildings. Transportation programs can require scheduled quantities, or nominations, and settlement of differences between scheduled and actual use. A supplier may manage these functions for a bundled fee or pass specified imbalance costs to the customer. Ask who receives utility notices, who changes nominations during cold weather, and what happens under an operational flow order. A low commodity adder is not a complete measure of the account’s risk.

Normalize units before comparing prices

Gas meters commonly measure volume while contracts may price heat energy in therms or MMBtu. One therm equals 100,000 Btu, and ten therms equal one MMBtu. Converting Ccf or Mcf into energy requires the applicable heat-content factor, and sometimes utility volume corrections. Use bill-specific factors instead of assuming every cubic foot contains the same energy. Identify whether pipeline transport, fuel retention, balancing, storage, and distribution are included in each quoted price.

Hypothetical winter purchasing review

A building expects 2,000 MMBtu of winter consumption. Two offers with the same nominal commodity price can differ if one includes daily balancing and the other passes deviations through. Request cost scenarios for colder-than-expected use and an operational restriction before choosing. Do not model a fixed commodity price as protection from every transportation penalty. For an interruptible account, also examine backup-fuel capability and the process for responding safely to an interruption notice.

Practical review checklist

• Confirm choice or transportation eligibility, service firmness, and all utility enrollment requirements.
• Collect monthly and, where available, daily usage plus the contract’s gas pricing units.
• Allocate nomination, imbalance, operational-flow-order, and emergency-notification responsibilities in writing.
• Review commodity, basis, transport, fuel, storage, and LDC delivery without counting a charge twice.
