NOTICE OF CHANGE IN THE RATE TARIFFS OF UNITED POWER, INC.

DATE OF NOTICE:  Nov. 7, 2025

United Power Inc.’s elected board of directors has approved changes to United Power’s rate tariff schedules for energy usage, including increases to both demand and fixed charges, to become effective on or after Jan. 1, 2026, as described on each applicable rate tariff posted on www.unitedpower.com. Additionally, the on-peak window for residential and commercial time of use rates will change from the current window of 2:00 p.m. to 10:00 p.m. to a shorter window of 5:00 p.m. to 9:00 p.m. These adjustments are necessary for all rate classes due to increased wholesale power and transmission costs, increased costs due to tariffs and continued inflationary pressures on the supply chain, and to keep United Power in compliance with its indenture, note purchase agreements, and financial goals. There will also be a new rate class labeled Municipal Owned Lighting Service (MOL).

The present and proposed tariff provisions are available for examination at the Coal Creek Branch Office, located at 5 Gross Dam Road, Golden, CO; the headquarters office located at 500 Cooperative Way, Brighton, CO; the Carbon Valley Branch Office at 9586 E. I-25 Frontage Road, Longmont, CO; and on the cooperative’s website at www.unitedpower.com.

Anyone who desires to file either an informal complaint or a formal complaint with United Power must do so in writing as required by United Power’s Rules and Regulations, accessible online at www.unitedpower.com/bylaws-rates-tariffs.

MORE INFORMATION: United Power 2026 Rate Change Information

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.

Sending Aid to Power the Navajo Nation

Miles of vacant desert land often separate homesteads in the sparsely populated territory of the Navajo Nation. The summer months are a grueling combination of temperatures exceeding 100 degrees and very little moisture. And many of the Nation’s people still endure the environment without access to electricity. 

The Light Up Navajo initiative was launched as a collaboration between the Navajo Tribal Utilities Authority (NTUA) and the American Public Power Association to bridge this gap in electrification. The initiative’s sixth project since 2019 aimed to power 175 homes in remote parts of the Nation this summer.

Four United Power lineworkers volunteered to participate in the summer project. They were dispatched to New Mexico for a week in July. The crew included Foreman Zach Reynolds, Journey Lineworkers Ted Pierce and Dillon Scroggins, and Apprentice Lineworker Isaiah Segoviano. 

“I did not know what to expect when I volunteered for this project,” said Reynolds. “It was a very humbling and eye-opening experience. It is crazy to think that we have the luxury of power every day, but we get upset and complain when the power goes out. Some of the Navajo people have lived more than 50 years without power.”

Reynolds and his crew would wake up as early as 5 a.m. to drive to the staging station before spending nearly an hour on the road to their work site. They spent the week setting poles and hanging line extensions under the hot sun. 

It was frequently a challenge to set poles because of the loose dirt embedded with small stones and rocks. Using traditional equipment to dig post holes was nearly impossible due to the conditions, and it was common for holes to collapse. 

The week ended with a larger project that included setting 40 poles to power a single residence on an isolated plot of land. Its occupants were the grandchildren of a former World War II code talker, a special unit of Marines who used their native Navajo language to create and transmit coded messages during the war. They were a crucial element in the victory. 

“He was a code talker and a prisoner of war,” said Reynolds. “He waited his whole life to see his home energized, but he sadly passed just before our project powered his home.” 

Reynolds said the NTUA emphasized meeting the families who received power.

“Meeting the families and hearing their testimonies was one of the most memorable experiences,” he said. “Until you see how they live, you don’t have any idea how impactful and life-changing this was for them.” 

United Power crews have volunteered to help with Light Up Navajo on three separate projects since July 2024. The cooperative will continue to support this initiative on future projects. 

Brighton, CO – United Power, Inc. today announced it has entered into an agreement with Aypa Power for the Fortress project, a hybrid renewable energy project that will combine 200 megawatts (MW) of solar with 150 MW / 600 megawatt-hours (MWh) of battery energy storage near the City of Brush in Morgan County.
 
Scheduled to come online in 2027, Fortress will generate and store power for United Power members under a long-term power purchase agreement. The project supports the cooperative’s ongoing efforts to strengthen grid reliability and manage long-term power supply costs through a more diverse and locally sourced energy portfolio.
 
“United Power continues on a path to diversify and localize the power we purchase and deliver to our members,” said Mark A. Gabriel, United Power President and CEO. “We are investing in local projects that create a more robust generation system, which, in turn, will help us stabilize electric costs while investing in area economies. As the country grapples with the rising price of electricity, the cooperative is actively managing costs and seeking additional local generation resources. We believe our vision of a hyperlocalized electric system is the future of power production and it is an investment that will benefit all our members.”
 
Since leaving its former wholesale power provider in May of 2024, United Power has continued to invest in a portfolio of locally produced power sources, including several renewable energy and battery storage projects. Projects like Fortress represent significant investments in the state, helping ensure tax revenue and job creation benefit the communities United Power serves, while supporting a more resilient and member-focused energy network.

“Aypa Power is pleased to partner with United Power to bring the first phase of a 600 MW solar and battery storage complex online in Colorado,” said Dan Santelli, Chief Commercial Operator at Aypa Power. “Fortress will deliver low-cost energy and provide critical reliability, while supporting United Power’s commitment to dependable and locally sourced power.”

Members Invited to Celebrate Cooperative Contribution

United Power is an electric distribution cooperative. That means it is wholly owned by the members it serves and is designed to meet community needs. Co-ops exist across a multitude of markets and industries, including food and agriculture, finance and banking, consumer retail, insurance, healthcare, and more. Distribution co-ops, like United Power, were formed more than 85 years ago when farmers and business owners in rural areas of the country recognized the need and benefit of electricity and found a way to provide it. Today, there are more than 900 such cooperatives providing power to nearly 75% of the country’s landmass and contributing more than 40% of the nation’s electric grid. 

October is National Co-op Month, and members are invited to join in celebrating the contributions of cooperatives in our lives. Co-ops are different from their for-profit counterparts by a commitment to empowering local communities and encouraging a spirit of service. 

United Power serves some of the fastest growing cities not just in Colorado but in the country. The cooperative is an innovative energy partner helping meet the growing needs of these transforming communities. It also helps coordinate economic development, supports local nonprofits aiding residents, and sponsors programs that enhance each community. Many employees live, work, play, and serve locally. Their faces are recognizable on local chamber of commerce and nonprofit boards or at fairs, festivals, and other community events.

United Power puts money back into the community every year through scholarships, youth development, sponsorships, and more. The cooperative awarded more than $35,000 in scholarships to local high school students in the spring and four additional scholarships worth $7,500 to students enrolled in a dedicated lineworker program in December. Six students were selected to represent the co-op on youth leadership trips to Washington, D.C. and Steamboat Springs, where peers elected one of them to return as an ambassador next summer. This summer, United Power was once again the Adams County Fair’s presenting sponsor, in addition to supporting community celebrations and events in Fort Lupton, Frederick, Mead, Keenesburg, Gilpin County, and more. 

While United Power’s first priority is ensuring the safe and reliable distribution of electricity to its residential, commercial, and industrial members, the cooperative is more than just your neighborhood energy provider. It is powered locally by local people, supporting the growth, development, and prosperity of the communities they — and you — call home.
