Title Graphic About the Most and Longest Power Outages by U.S. State

With the constant threat of severe storms, losing power is an inconvenience homeowners and businesses alike can expect. Tropical Storm Risk predicts hurricane activity in the North Atlantic this year could be 50% above the last 50-year norm. Understanding which states are most affected by power outages can help residents better prepare when their electricity fails.

At MRO Electric, we wanted to determine which U.S. states are most at risk of power outages. To find out, we analyzed data from the U.S. Energy Information Administration to determine the average frequency and duration of power outages in each state. Specifically, we used outage data from their annual reports for the last five years (2018-2022). Keep reading to see how your state stacks up.

The U.S. States with the Most and Least Power Outages

With the most annual power outages, Maine is surely left in the dark. The Pine Tree State tops the list with an average of 4.35 power outages every year, a stark increase above the national average of 1.62 per year.

Given that severe weather can lead to outages, it is no surprise that Louisiana is ranked third on our list. According to the National Hurricane Center and USAFacts, Louisiana is one of the most hurricane and tornado-prone states, and with about 2.78 power outages a year, it is not hard to see what is causing these blackouts.

Mississippi, with the most annual tornadoes on average, and Florida, the most hurricane-prone state, also suffer from outages with 2.25 and 2.18 outages per year on average, respectively. The South, with its frequent severe storms, was the region with the most power outages on average and these states certainly contributed. Comparatively, the South experiences about 1.97 power outages a year, the Northeast encounters about 1.64, the West has about 1.50 on average, and the Midwest comes in last with about 1.31 power outages in a year.

The District of Columbia suffered the least from power outages, with about 0.47 per year on average. Utah and Wisconsin are close second and third with 0.60 and 0.75 annual outages, respectively.

Another factor that should be considered when determining the severity of a power outage is how long the outage lasts. Now, let’s take a look at which states had the longest and shortest power outage durations.

The U.S. States with the Longest & Shortest Power Outages

As mentioned earlier, Louisiana is a hurricane and tornado-prone state. This may be why Louisiana has the longest average annual power outages of any state, with an annual average of more than a full day without power (24 hours and 54 minutes), which is four times the national average of 6 hours. Following Louisiana, Maine, with the most average annual outages, also had some of the longest outages lasting up to nearly 16 hours.

Once again, D.C. fares well in terms of outages and has the shortest average annual power outage duration at only an hour of no power on average, which is just a fraction of what Louisiana suffers. Delaware (1 hour and 42 minutes) and Utah (1 hour and 54 minutes) follow, with an average power outage duration of less than two hours. To see more averages of power outage duration, see the map above.

Let’s Shed Some More Light on the Matter…

When evaluating frequency and duration patterns of power outages, major event days (MED), are occurrences that are factored in and necessary for understanding the severity of each. Major event days are defined as any day where outage metrics exceed normal averages. While these can sometimes be attributed to hackers, cyber attacks, and other anomalies, they are usually caused by severe weather patterns like hurricanes and blizzards.

To take a closer look at these power outage metrics across the country, hover over each state in the interactive map below. Find out what you can expect for where you call home.

PLCs offer flexibility and versatility, enabling engineers and technicians to modify and adapt control logic easily without the need for extensive rewiring or hardware changes.

At the core of a PLC is its Central Processing Unit (CPU), responsible for executing control programs stored in memory. The CPU reads and interprets the instructions, making decisions based on the programmed logic. It then sends signals to output devices such as motors, valves, and sensors. Input modules gather data from the field through various sensors and switches, converting analog or digital signals into a format that the PLC can comprehend. Conversely, output modules translate the processed information from the CPU into signals that control the physical components of the automated system.

The Four Components

Central Processing Unit (CPU)

At the heart of every PLC is the Central Processing Unit (CPU). This component is the brain of the PLC, responsible for executing control programs and processing inputs and outputs. The CPU reads the program from memory, interprets the instructions, and sends signals to the output devices based on the program’s logic. Modern PLCs come with powerful CPUs capable of handling complex control tasks and communication with other devices on the industrial network.

Input Modules

Input modules are responsible for interfacing the PLC with the external world by collecting data from various sensors and switches. These modules convert analog or digital signals from field devices into a format that the PLC can understand. Digital input modules handle binary signals (on/off). In contrast, analog input modules process continuous signals such as voltage or current. Input modules are crucial for monitoring the state of the controlled system and providing real-time feedback to the PLC’s CPU.

Output Modules

Output modules facilitate communication between the PLC and the external devices such as motors, valves, or actuators. These modules convert signals from the CPU into a form that can control the physical processes in the industrial environment. Just like input modules, there are digital output modules for binary control and analog output modules for continuous control. The accuracy and reliability of output modules are vital for ensuring that the controlled system responds appropriately to the PLC’s commands.

Memory

PLCs have two types of memory: RAM (Random Access Memory) and ROM (Read-Only Memory). RAM is used for storing the control program and data temporarily while the PLC is powered on. ROM contains the firmware and the operating system that are essential for the PLC’s functionality. The memory capacity of a PLC varies, and it is crucial to choose a PLC with sufficient memory to accommodate the complexity of the control program and the amount of data processing required.

Conclusion

Programmable Logic Controllers have revolutionized industrial automation, providing a robust and flexible solution for controlling and monitoring complex processes. Understanding the four main components of a PLC – CPU, Input Modules, Output Modules, and Memory – is fundamental for anyone working in the field of industrial automation. As technology advances, PLCs continue to evolve, incorporating new features and capabilities. Furthermore PLCs enhance their role in modern manufacturing and industrial processes.
