Choosing Between Natural Gas and Propane Generators: Your Complete Guide for Dallas County Homes in 2024

When severe weather strikes Dallas County, reliable backup power becomes essential for protecting your home and family. The 2021 Texas winter storm left over 4.5 million homes and businesses without power, causing at least 210 deaths and leading to a sudden rise in demand for backup generators in our region. As homeowners increasingly recognize the importance of emergency preparedness, the question isn’t whether to install a generator—it’s which fuel source will best serve your specific needs.

Understanding Your Fuel Options

Natural gas generators offer the convenience of a continuous supply, as the fuel is delivered via a pipeline. This setup means there’s no need for manual refueling, making it a hassle-free option for sustained use. Natural gas burns cleaner than many other fossil fuels, producing fewer emissions, and is generally more cost-effective over long term use. However, its use is dependent on the availability of a natural gas line, which can be a limitation in remote areas, and in severe weather or disasters, the natural gas supply can be disrupted, affecting its reliability.

Propane generators present a different set of advantages. Propane generators are known for their energy efficiency and long shelf life. The fuel can be stored indefinitely, making propane a reliable option for emergency power. These generators are efficient, producing more energy per unit of fuel compared to other types. Propane is used as a generator power rating because of its high energy density. In other words, per unit volume, propane packs more energy than natural gas. This leads to efficient fuel consumption, with generators requiring less propane to produce the same amount of electricity compared to natural gas.

Performance and Efficiency Considerations

The energy output difference between these fuel sources is significant for Dallas County homeowners. One cubic foot of propane yields 2,516 BTUs, while the same volume of natural gas provides 1,030 BTUs. In terms of energy density and consumption, propane requires less volume to produce a specified BTU output compared to natural gas. This means a generator’s power output, when fueled by propane, might range between 7kW to 20kW — ample to electrify an average-sized home. In contrast, that same generator, when running on natural gas, might only yield up to 18kW.

For practical applications, a 10-kilowatt generator typically consumes about 2.2 gallons of propane every hour, while an average 10 kW generator running on natural gas is likely to burn approximately 1.5 gallons of gas per hour. While natural gas shows lower consumption by volume, propane’s higher energy density often makes it more efficient for power generation.

Cost Analysis for Dallas County Residents

Natural gas is usually a more affordable option than propane, particularly for homeowners who already have natural gas service to their property. A natural gas generator cost is often lower than a propane generator, making it a more budget-friendly option. The lower natural gas generator cost also makes it a more affordable option. However, propane generators are often more expensive upfront compared to natural gas generators. The cost per unit of energy (BTU) is higher compared to natural gas, making it a less cost-effective option in the long run.

The total cost equation includes installation expenses, ongoing fuel costs, and maintenance requirements. Propane generators are typically less expensive than natural gas generators. Those who have access to a natural gas line typically spring for NG generators since the cost of fuel is less expensive by unit.

Installation Requirements and Dallas County Regulations

Dallas County homeowners must navigate specific regulations when installing generators. Dallas has specific regulations governing generator installations. These include building permits from Dallas Development Services, electrical permits, compliance with Dallas Fire-Rescue Department requirements for fuel storage, and adherence to local noise ordinances. Professional generator installation Dallas County, TX requires expertise in local codes and permitting processes.

Environmental compliance includes adherence to Texas Commission on Environmental Quality (TCEQ) regulations regarding emissions, particularly for larger generators that may require air quality permits. Additionally, generators over certain sizes may require air quality permits from the Texas Commission on Environmental Quality (TCEQ). For generators installed in flood-prone areas of Dallas, additional elevations or protections may be required. Zoning restrictions may also affect where generators can be placed, particularly in mixed-use or historically designated areas.

Reliability and Maintenance Factors

Both fuel types offer distinct reliability profiles. Natural gas provides access to a constant fuel supply which eliminates worries over whether or not you’ll have enough fuel during a long power outage. However, natural gas systems can be vulnerable during severe weather events that damage infrastructure.

Unlike natural gas, propane can be stored indefinitely without degrading. If you’re concerned about a backup for infrequent power outages, propane is a good choice. With liquid propane, you can have your fuel delivered to guarantee a full tank before a big storm. LP can last indefinitely if the propane is stored safely.

Making the Right Choice for Your Dallas County Home

The decision between natural gas and propane generators depends on several key factors specific to your situation. When deciding between propane and natural gas generators, consider: Do you live in an area with reliable natural gas supply, or would a propane tank be more practical? If reducing your carbon footprint is a priority, natural gas is the cleaner option. Propane requires safe storage space for tanks, whereas natural gas needs a stable pipeline connection.

If you already have a reliable source of natural gas and need a stationary generator with low maintenance needs, a natural gas system is an ideal choice. If you want portability, long-term storage, and flexibility, propane generators are usually the better choice.

Professional Installation Matters

Regardless of your fuel choice, professional installation ensures safety, code compliance, and optimal performance.

Professional installation helps determine the right size generator for your home’s electrical needs and handles all the necessary permits and inspections.

Both natural gas and propane generators offer valuable benefits for Dallas County homeowners. Natural gas provides convenience and lower operating costs for homes with existing gas service, while propane offers superior energy density and fuel storage flexibility. The reality is that differences between the major fuel sources are pretty minor in a grand scope. If you could choose either one, we would probably recommend Propane as the first option, because of its higher efficiency, but the best fuel source will continue to be the one that is most available to you. Consider your specific circumstances, including existing utilities, budget, and backup power needs, when making this important decision for your home’s emergency preparedness.
