What Is a Therm and Why Does It Matter?
Before diving into cost analysis, it’s essential to understand what a therm actually represents. A therm is the standard unit of measurement for natural gas consumption, equal to 100,000 British Thermal Units (BTUs). A BTU measures the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.
When you look at your natural gas bill, you’ll see your consumption measured in therms (or sometimes in CCF, which equals 100 cubic feet). One CCF is approximately equal to 1.037 therms. Understanding this measurement is crucial because it allows you to compare prices across different providers and periods accurately.
Natural Gas Measurement Units Conversion
| Unit | Equivalent | Description |
|---|---|---|
| 1 Therm | 100,000 BTUs | Standard unit for pricing natural gas |
| 1 CCF | 100 cubic feet | Volumetric measurement used by utilities |
| 1 CCF | ≈1.037 therms | Conversion from volume to energy content |
| 1 MCF | 1,000 cubic feet | Larger volumetric measurement |
| 1 MCF | ≈10.37 therms | Conversion from volume to energy content |
Factors Affecting Natural Gas Cost Per Therm
Natural gas prices aren’t static—they fluctuate based on numerous factors. Understanding these variables can help you anticipate price changes and manage your energy expenses more effectively.
Supply and Demand Dynamics
The fundamental economic principle of supply and demand heavily influences natural gas prices. When production increases or storage levels are high, prices tend to decrease. Conversely, when supply is limited or storage levels are low, prices typically rise. The U.S. Energy Information Administration (EIA) provides weekly updates on natural gas storage that can impact market prices.
Seasonal Demand
Natural gas consumption follows a seasonal pattern, with higher demand during winter months for heating and during summer months in regions where natural gas powers electricity generation for air conditioning. This seasonal demand creates price fluctuations throughout the year.
Weather Patterns
Extreme weather events, both hot and cold, can significantly impact natural gas prices. Extended cold snaps increase heating demand, while heatwaves can boost electricity generation needs. Additionally, hurricanes in the Gulf of Mexico can disrupt production and transportation infrastructure, leading to temporary price spikes.
Infrastructure and Transportation Costs
The cost of transporting natural gas from production areas to consumers affects the final price. Regions closer to natural gas sources or major pipelines typically enjoy lower prices than remote areas that require extensive infrastructure.
Regulations and Taxes
Government regulations, environmental policies, and taxes can all influence the final cost of natural gas. State and local taxes vary significantly across the country, contributing to regional price differences.
Regional Variations in Natural Gas Costs
Natural gas prices vary considerably across the United States due to factors like proximity to production areas, infrastructure availability, regional demand, and state regulations. Understanding these regional differences can help you benchmark your costs against national averages.
Average Natural Gas Prices by Region
| Region | Average Price per Therm | Compared to National Average |
|---|---|---|
| Pacific | $1.45 | 45% higher |
| Mountain | $0.85 | 15% lower |
| West North Central | $0.95 | 5% lower |
| East North Central | $0.90 | 10% lower |
| South Atlantic | $1.10 | 10% higher |
| East South Central | $0.80 | 20% lower |
| West South Central | $0.70 | 30% lower |
| Middle Atlantic | $1.20 | 20% higher |
| New England | $1.50 | 50% higher |
The West South Central region, which includes major natural gas-producing states like Texas and Louisiana, typically enjoys the lowest prices due to proximity to production. In contrast, New England and the Pacific states often face higher prices due to limited infrastructure and greater distance from production areas.
Calculating Your Natural Gas Costs
To calculate your natural gas costs, you’ll need to understand the rate structure used by your utility provider. Most utilities use either a flat rate or a tiered rate structure.
Flat Rate Calculation
With a flat rate structure, the calculation is straightforward: Total Cost = (Monthly Service Charge) + (Price per Therm × Number of Therms Used)
Tiered Rate Calculation
Some utilities use tiered pricing, where the price per therm increases as consumption rises: Total Cost = (Monthly Service Charge) + (Price per Therm for Tier 1 × Therms in Tier 1) + (Price per Therm for Tier 2 × Therms in Tier 2) + …
Example Natural Gas Cost Calculation
| Component | Calculation | Amount |
|---|---|---|
| Monthly Service Charge | Fixed fee | $15.00 |
| First 50 therms @ $0.80/therm | 50 × $0.80 | $40.00 |
| Next 50 therms @ $0.90/therm | 50 × $0.90 | $45.00 |
| Additional therms @ $1.00/therm | 20 × $1.00 | $20.00 |
| Taxes and Fees | 5% of energy charges | $5.25 |
| Total Bill | $125.25 |
Natural Gas Cost Per Therm Compared to Other Energy Sources
To put natural gas costs in perspective, it’s helpful to compare them with other common energy sources. This comparison should consider both the cost per unit of energy and the efficiency of the appliances using that energy.
Cost Comparison of Common Energy Sources
| Energy Source | Unit | Cost per Unit | BTUs per Unit | Cost per Million BTUs |
|---|---|---|---|---|
| Natural Gas | Therm | $1.00 | 100,000 | $10.00 |
| Electricity | kWh | $0.15 | 3,412 | $43.96 |
| Heating Oil | Gallon | $3.50 | 138,500 | $25.27 |
| Propane | Gallon | $2.80 | 91,500 | $30.60 |
Note that this comparison doesn’t account for appliance efficiency. For example, while natural gas appears much cheaper than electricity per BTU, electric heat pumps can be 200-400% efficient, whereas natural gas furnaces are typically 90-98% efficient. This efficiency difference narrows the cost gap for heating applications.
