Reliability Outperforms National Averages Year-Over-Year

Members expect consistently reliable power from their electric utility. United Power has maintained a standard of excellence in system performance, delivering results that far exceed the national average year-over-year. The cooperative has continued to meet this standard while it navigated a power supply transition last year and is incorporating new, innovative projects that source and store power locally. 

The cooperative’s exit from its wholesale power contract in May of 2024 meant bringing on new contracts from a mix of traditional and sustainable resources into the distribution system. Aside from celebrating United Power’s energy independence, the switch was successfully executed without any power disruptions, ensuring members can count on the cooperative to maintain its standards for reliability and resiliency across the distribution system.

United Power has collected 18 months of data since the transition, demonstrating consistent system reliability.

Measuring Reliability, By the Numbers

Electric utilities use a variety of key performance indicators to measure how effectively and efficiently their systems are operating. The most common indicator is known as the System Average Interruption Duration Index, or SAIDI. United Power also tracks the System Average Interruption Frequency Index, or SAIFI. These indicators are among the many used by utilities to analyze system performance and calculate outage expectations for an average member. 

SAIDI is the measurement of cumulative outage time (in minutes) an average member would expect to experience over the course of a year. The national average across all electric utilities was 131 minutes in 2024 and nearly 240 minutes for cooperatives, according to the Energy Information Administration (EIA). United Power’s SAIDI score has stayed below 80 minutes each of the past three years and is just above 60 minutes through September of this year.

SAIFI measures the total number of outages an average member would expect to experience over the course of a year (frequency of outages experienced). United Power’s score of 0.90 in 2024 means the average meter experienced fewer than one outage throughout the year, again exceeding the national average across all electric utilities (1.07) and other cooperatives (1.61), per the EIA. Put another way, most United Power members were unlikely to experience more than one outage last year, and many did not experience an outage at all. 

Another performance indicator used by utilities measures the system’s overall availability rate. The co-op’s three-year availability rate was between 98.8% and 99.9%. 

“Our system’s performance is due to the great effort of our engineering and operations teams,” said Mark A. Gabriel, United Power’s President and CEO. “They are responsible for reviewing and interpreting data and developing strategies to improve the system. We are setting the standard for other utilities while meeting our members’ expectations.”

Building a Better System

United Power’s approach to maximizing system performance utilizes a comprehensive combination of design practices, proactive maintenance projects, and extensive integration of automated and smart field devices. 

Outages are an intrinsic reality for electric utilities. United Power can mitigate them, but cannot guarantee they will not happen. Mitigation begins with building the system so that outages are recognized earlier, impact fewer members, and are restored quickly — and more importantly, safely. The cooperative designs the system with these steps in mind. 

One of the ways this is accomplished is known as a “redundancy.” This essentially means that power can be rerouted from an alternate source to restore members during an outage while crews are investigating the cause or working on repairs. Most members are on a redundant system, which is part of why United Power’s average restoration times are also among the best in the country. 

Another design strategy is “sectionalizing.” This means that when a fault results in an outage, depending on where it is located down the line, it may affect fewer members. Devices are installed in sections throughout the distribution system to limit outage impact. 

United Power also deploys automated devices that collect system data. That information can help locate and clear faults to minimize outages and reduce restoration times or identify infrastructure that is not performing optimally and needs to be repaired. This data has been helpful in the cooperative’s maintenance plan, which proactively targets the worst-performing sections of the system to improve reliability and increase resiliency. 

United Power outperforms other electric utilities across the various metrics used to evaluate system performance, but the cooperative regularly reviews emerging strategies and innovative technologies that can further improve reliability. Delivering safe and reliable power is the co-op’s core responsibility to members. You can be sure it is not taken lightly.

These days it is easy for national headlines and political turmoil to distract us from the prime directive of electric cooperatives like United Power, which is to safely keep the lights on in the most cost effective and sustainable way possible.

Every day and night the women and men of United Power are clearly focused on our mission. There is an old saying, loosely adopted by the U.S. Postal Service, from the translation of Herodotus’ Histories that says, “It is said that as many days as there are in the whole journey, so many are the men and horses that stand along the road, each horse and man at the interval of a day’s journey; and these are stayed neither by snow nor rain nor heat nor darkness from accomplishing their appointed course with all speed.” This is more appropriately the mantra of the people at United Power who work 24 hours a day, seven days a week, 365 days a year in some of the most challenging weather conditions to ensure the lights stay on.

We have a tremendous team — from the dispatchers working around the clock to the crews who build the system to the engineers planning the system to the member services representatives answering your questions. Every one of our 200+ employees does their part. They are dedicated to your cooperative with the support of our visionary Board of Directors who spend countless hours guiding the execution of Our Cooperative Roadmap.

Federal funding cancellations affecting projects are indeed disappointing — and confusing as the entire industry faces challenges brought on by significant increases in electric demand. Our actions are focused on physics, not politics, and we will continue to make sure we have a diverse portfolio of hyper-localized resources, coupled with power from a variety of transmission-delivered electricity. 

We recently contracted for the Fortress Project, a 200 megawatt (MW) solar project supported by 150 MW of battery storage. Combined with our existing 119 MW of batteries, United Power leads the way in the West.

Data centers receive a lot of blame for increasing energy costs, but that is only a fraction of the pressure on rates. While there is a narrative that data centers support the artificial intelligence invading our lives, many of us believe requiring these companies to invest in upgrades and support of renewable energy mandates will actually help lower rates. United Power’s LIT (location, investment, and timing) process requires developers of large projects to pay for the costs of infrastructure. This process, once further utilized and refined, is expected to be a model for other utilities.

There are other realities we are facing. The inflationary pressures on equipment are dramatic. We see this in our everyday lives at the grocery store but certainly in the materials we need to purchase to keep the lights on. Over the past several years the cost of things as simple as a basic work truck have gone up more than 30%, steel and aluminum have increased significantly due to tariffs, and health care costs continue to climb beyond the rate of inflation. 

At United Power we have moved ahead on a new asset management system that will allow us to focus on replacing equipment at the right time, manage inventory more efficiently, and understand problems before they spread widely. Additionally, the partnership with all of you, our members, as we move toward becoming a distribution system operator (DSO) means we will be able to aggregate local generation in support of the market when it comes in April 2026.

We do have some additional challenges that must be addressed. The lack of transmission — which is exacerbated by local utilities trying to control the lines for their own benefit — is one of the critical issues we are attacking. Meeting the state’s 2030 emissions requirements is harder because of this situation, but I am confident in the great team at United Power and their ability to find a solution.

As always, please feel free to reach out with any comments or questions. It is my honor to serve as your President and CEO and to lead this team of amazing people.
