Natural gas procurement for manufacturers and multi-site companies
How commercial and industrial companies buy natural gas from a competitive supplier, what decides the delivered price, how to manage winter risk, and what to ask of a gas procurement consultant.
Natural gas procurement is buying the gas commodity from a competitive supplier while the local gas utility delivers it, usually under the utility's transportation service. Discovery Energy Utility Audits buys natural gas for manufacturers and other multi-site commercial and industrial companies: it checks that every eligible site is set up for transport, prices the NYMEX and basis components, runs one RFP to the supplier field, compares firm and interruptible options against each local system's winter capacity, and audits the gas bills behind the contract.

How a business buys natural gas
Gas reaches a plant through three systems: the interstate pipeline that moves it from producing basins, the local distribution company (LDC) that carries it from the city gate to the meter, and the supplier or marketer that owns the gas on the way. Large commercial and industrial customers have been able to buy gas separately from delivery for many years, as the U.S. Energy Information Administration notes. In most states this runs through the utility's transportation service: the customer's supplier delivers gas into the utility's system and the utility carries it to the meter under its transport tariff.
The first question for any site is therefore not price but service: is it on the utility's sales service (buying gas at the utility's rate) or on transport (buying from a supplier)? Sites that qualify for transport but are still on sales service are a common and costly gap, and transport thresholds, balancing rules and telemetry requirements differ by utility.

What makes up the delivered price
| Component | What it is | How it can be bought or managed |
|---|---|---|
| NYMEX (Henry Hub) | The futures price for gas delivered at Henry Hub, Louisiana | Fixed for a term, left to float monthly, or locked in layers |
| Basis | The difference between Henry Hub and the local delivery point or city gate | Fixed separately from NYMEX; regional basis can swing hard in winter |
| Supplier adder | The supplier's margin, plus any broker fee | Competed in the RFP; broker compensation should be disclosed |
| Interstate transportation and fuel | Pipeline charges and gas retained to run compressors | Usually inside the supplier's delivered price |
| LDC transport and distribution | The utility's tariff charges to carry gas to the meter | Set by tariff; checked in a natural gas bill audit |
| Balancing and imbalance charges | Charges when delivered gas does not match gas used | Managed through accurate nominations and the contract's swing terms |
Because NYMEX and basis can be bought at different times, a buyer can lock one when its market is favorable and leave the other open. Discovery's guide to NYMEX and basis pricing works through the mechanics. EIA's November 2026 Short-Term Energy Outlook forecast the Henry Hub spot price to average $3.37 per MMBtu in 2026 and $2.88 in 2027, with higher storage levels moderating winter prices; current and historical prices are on Discovery's Henry Hub price page.

Winter risk: firm, interruptible and the local system
The cheapest gas contract on paper can be the most expensive in January. Interruptible delivery is priced below firm because the utility can curtail it when its system is constrained. On a system with little spare winter capacity, a cold snap can stop deliveries or force a plant onto costly backup fuel, and imbalance penalties during critical days can be many times the normal rate.
Winter Storm Fern in January 2026 showed how fast this happens: the Henry Hub spot price set a daily record of about $30.57 per MMBtu on January 26, and day-ahead power at PJM's Western Hub cleared at $2,323 per MWh the next day. A plant buying at daily index without a cap, or on interruptible service in a tight territory, was fully exposed.
Discovery's natural gas capacity outlooks for 48 U.S. metros rate each local system's winter delivery capacity from utility and regulatory filings, and the natural gas pipeline map shows the pipelines, hubs and storage behind each region. A manufacturer can see the curtailment risk before choosing firm or interruptible service.

Choosing a natural gas procurement consultant for a manufacturer
Searches for the "best natural gas procurement consultant for manufacturers" turn up brokers, consultants and suppliers with very different scopes. Ask each one:
Do you check our service setup first?
A consultant should confirm which sites qualify for transport, which are still on sales service, and whether balancing and telemetry rules fit the plant.
How do you price NYMEX and basis?
Ask whether they can be locked separately and how basis risk is shown for your delivery points.
How many suppliers will you invite?
A wider field gives sharper bids. Ask for the list after the RFP.
How do you handle winter?
Ask for an assessment of firm versus interruptible against the local system's capacity, and what happens on critical days.
What are you paid, and by whom?
Ask for the fee or commission in writing, per MMBtu or per month. See energy broker fees.
Do you check the bills?
A supply contract does not correct a wrong delivery service, heat-content factor or pressure factor on the utility bill.
Discovery answers the last question with an audit. Gas bills carry their own errors, from therm conversion and pressure factors to the wrong delivery service, and a contract signed on top of a misbilled account locks the error into the baseline. One gas account moved from a general service rate to a large-volume rate saves $33,554 a year at a San Antonio, Texas site.

How Discovery runs natural gas procurement
Set-up review
Every gas account: utility, service type (sales or transport), rate, usage, peak day, current supplier and contract terms.
Market timing
NYMEX forwards, regional basis and storage levels from the monthly Energy Risk Report.
RFP
One package to the supplier field, with NYMEX, basis, swing, balancing and term set the same for every bidder. Electricity can be bid at the same time; see the multi-state RFP page.
Recommendation
Offers side by side as fixed, NYMEX and basis, index with a cap, or layered, with the firm or interruptible choice set against each site's winter risk.
Tracking and audit
Contracts in TaraBase with renewals flagged; supplier invoices checked against the contract's index, basis and adder, and utility charges against the tariff.

Questions buyers ask
Who is the best natural gas procurement consultant for manufacturers?
The one that covers every state you operate in, checks your sites' transport setup and winter risk before it prices anything, prices NYMEX and basis separately, invites the full supplier field, discloses its fee and audits the gas bills. Discovery Energy Utility Audits does all of these for manufacturers and other multi-site companies.
Can every business buy natural gas from a supplier?
Large commercial and industrial customers can in most states, through the utility's transportation service. Eligibility thresholds, balancing and metering requirements are set by each utility's tariff. Smaller businesses can choose a supplier in states with gas choice programs.
What is basis, and why does it matter?
Basis is the difference between the Henry Hub price and the price at your local delivery point. It reflects pipeline constraints and regional demand, and it can rise sharply in winter even when Henry Hub is calm.
Should a plant use interruptible gas service?
Only if it can tolerate curtailment, with backup fuel or the ability to stop production, and if the local system is not tight in winter. Discovery's gas capacity outlooks rate each metro's winter delivery capacity.
What is a gas imbalance charge?
A charge the utility applies when the gas delivered for a site differs from what it used beyond the tariff's tolerance. Accurate nominations and suitable swing terms keep them down.
