Natural gas is one of the most important fuels in the United States. It heats homes, powers businesses, and supports industries. But the price of natural gas can be confusing. Unlike a single fixed price tag, it changes depending on many factors. These include production costs, transportation, weather, demand, and even global markets. For homeowners, this affects monthly heating bills. For businesses and energy professionals, it impacts planning and budgeting. To make sense of it, we need to look at how natural gas pricing structures work.
Types of Natural Gas Prices
Natural gas prices are not all the same. Some depend on where the gas is sold. Others depend on when it is delivered. Some are tied to market tools and pricing methods. These include wellhead prices, citygate prices, residential prices, spot prices, and futures prices. Understanding these types helps explain how costs move from production to your monthly bill.
Prices Based on Where Gas is Sold
Wellhead Prices
The wellhead price is the wholesale price at the point of production. This is the price producers receive when the gas leaves the ground. The government does not regulate it. Instead, the price is set by the competitive market.
Several things affect wellhead prices. Supply is a key factor. When there is more gas available, prices often fall. Demand is another factor. If people need more gas, such as during cold winters, prices rise. Weather plays a major role. Extremely hot or cold weather increases gas use for heating or cooling. Prices of other fuels, such as coal and oil, also influence wellhead gas prices. Finally, competition between gas companies for supply also has an impact.
Citygate Prices
The citygate price applies when gas moves from large pipelines to local utilities. It includes both the wholesale wellhead price and the cost of transportation. This means the citygate price is usually higher than the wellhead price.
Citygate prices vary a lot between regions. For example, a cold northern state may pay more in winter compared to a warmer southern state. The number of pipelines that serve an area also matters. If a region has only a few pipelines, competition is low and costs can rise. Regional demand, usage patterns, and even short-term weather events can cause major differences in citygate prices.
Residential Prices
The residential price is what households pay on their monthly bills. This price includes the cost of the gas itself plus delivery charges and taxes. The gas commodity makes up about two-thirds of the total bill. The remaining one-third comes from delivery service and government taxes.
By law, utilities cannot mark up the price of the natural gas itself. They sell it at the same cost they paid. Utilities make their profit through delivery and service fees. That is why the bill separates “commodity” and “delivery” charges.

Prices Based on Timing of Delivery
Short-Term Contract Prices
Utilities often buy gas under short-term contracts. These contracts last from one month to one year. A utility may agree on a contract price in the summer for gas to be delivered in the winter.
Short-term contracts help utilities secure gas at fair prices. They also spread the risk by signing contracts with different suppliers and different delivery dates. This way, customers get a reliable supply even during times of high demand.

Spot Market Prices
The spot market is used when utilities need gas quickly. Delivery happens within a few days. The spot market is very flexible. It allows utilities to react to sudden changes in weather or supply. Spot prices move up and down very fast. A cold front or sudden shortage can send prices up in just days. On the other hand, mild weather or strong supply can bring prices down. Because of this, spot prices are the most sensitive to market changes.
Long-Term Contract Prices
Some utilities also use long-term contracts. These contracts last for more than one year. They help provide a steady supply and protect against sudden market spikes.
Most utilities do not rely on just one type of contract. Instead, they use a mix of short-term, long-term, spot, and stored gas. This balance helps protect customers. If one price goes up, it does not immediately affect residential bills.

Other Price Concepts
Storage
Utilities often buy gas in the spring and fall when prices are lower. They store this gas for use in the winter. On average, storage provides about 20% of all gas used in winter. On the coldest days, storage can provide an even larger share. Storage helps smooth out demand and prevents shortages.
Price Indexing
Some contracts use price indexing. This means the gas price changes with market conditions. It may follow spot prices, futures prices, or even the price of other fuels like heating oil. Price indexing works like an adjustable-rate mortgage. The rate changes up or down depending on the market.
Futures Prices
The New York Mercantile Exchange (NYMEX) allows people to buy and sell contracts for future gas delivery. Futures contracts are mostly financial tools. They help buyers and sellers reduce risk. Most futures contracts do not involve actual gas delivery. Instead, traders buy and sell contracts and settle them before delivery. All futures contracts are tied to Henry Hub in Louisiana. Utilities do not usually use futures, but marketers and traders do. Futures add liquidity and stability to the gas market.
Purchased Gas Adjustment
The price shown on your bill is the same the utility paid for gas. Utilities make money from delivery, not from the gas itself.
Since market prices change often, regulators allow a purchased gas adjustment. This lets utilities pass changes in gas costs to customers. Some states adjust bills monthly. Others adjust quarterly or every six months. The more often adjustments are made, the faster customer bills reflect real market changes.
Conclusion
Natural gas pricing is complex prices can change depending on where gas is sold, when it is delivered, and how it is priced. Wellhead, citygate, and residential prices show how costs rise as gas moves from the ground to your home. Spot, short-term, and long-term contracts show how timing matters. Futures, storage, indexing, and purchased gas adjustments are other tools that affect pricing.
For homeowners and businesses, knowing these terms can help explain monthly bills. For energy brokers, understanding these pricing structures is key to planning and making smart choices. While natural gas markets can seem confusing, breaking them down into simple parts makes the system easier to follow.
