When your Southlake home loses power during an outage or severe storm, a generator can be a lifesaver, providing the electricity you need to remain safe and comfortable.

But do you know how long your generator will run during an extended blackout—and are you prepared? The answer depends on various factors, including the make and model of the generator, the fuel source, and the load it is powering.

At Generator Authority, we understand the importance of being prepared for power outages, and we are here to help you navigate the complexities of selecting the right generator for your needs. We install, service, and repair portable and standby generators.

Blackouts and Generator Usage

Extended blackouts can and do happen! They can occur from severe weather conditions, power grid failures, natural disasters, and more.

According to the U.S. Energy Information Administration (EIA), the average U.S. electricity customer experienced just over eight hours of power interruptions in 2020. While the length of outages depends on the region and other factors, it highlights the importance of having a reliable backup power source. 

Factors Influencing a Generator’s Run Time

Your generator’s run time will depend on the following:

  • Fuel Type and Capacity: Generators can run on various fuels like gasoline, diesel, propane, or natural gas. Each fuel type has its efficiency and capacity, which influences how long the generator can run.
  • Size and Power Output: The size and power output (measured in watts) of your generator are crucial. A larger, more powerful generator will consume fuel faster but will also be able to power more appliances. It is essential to balance the need for power with fuel efficiency.
  • Load: The number of appliances and devices you power with your generator greatly affects its run time. Running essential appliances only, such as refrigerators and lights, will extend the run time compared to powering an entire house.

    Be sure to consider which and how many appliances you want to use with the help of your generator if the power ever goes out.
  • Maintenance and Condition: Well-maintained generators are more efficient and have longer run times. Regular maintenance will help your generator run optimally when you need it.

Maximizing Your Generator’s Efficiency During Blackouts

To maximize the efficiency of your generator during a blackout:

  • Prioritize Essential Appliances: Limit the use of your generator to essential appliances. This not only conserves fuel but also ensures that you have power for the most critical needs.
  • Regularly Check and Refill Fuel: Keep an eye on your fuel gauge and have extra fuel on hand (stored safely) to refill the tank if needed.
  • Invest in a Fuel-Efficient Model: Consider investing in a generator known for its fuel efficiency. Newer models often have better fuel economy compared to older ones.
