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.”

There has been a lot of talk recently about “saving” certain forms of electric generation, stopping other types, and investing significant resources in technologies that are not ready for prime time. There have also been announcements about building thousands of miles of new transmission line.

When it comes to choices in generation, “all of the above” really needs to be “ALL of the above” if we are going to support electrification across the West and certainly for United Power. 

We recognize that diversity of resources is key to effectively running the cooperative, and we are taking action to ensure a safe, reliable, and affordable electric supply.

United Power partnered with Kindle Energy to open Mountain Peak Power in July. It is the newest and most efficient natural gas plant in Colorado. The 162 MW facility in Weld County provides critical electric capacity and is conveniently located near one of our substations that also has an 11 MW battery energy storage system. This project is a great example of our hyper-localization strategy and highlights the vision we laid out in Our Cooperative Roadmap. The plant was permitted in 10 months and constructed in 10 months. The same project today would take at least four years to obtain the needed equipment at 50% greater cost. 

We are also in the final stages of negotiations for an additional 200 MW of solar, bolstered by 150 MW of battery storage, to replace other expiring thermal generation contracts. These will come online in 2027. The solar facility will be among the largest in Colorado, increasing the carbon-free generation resources in our portfolio to nearly 64% and representing a continued reduction in greenhouse gas emissions since leaving our former wholesale power supplier in May 2024. 

The cooperative pioneered the use of distributed batteries with 115 MW spread across our system at nine substations, ranging in size up to 33 MW. Our engineering team has developed a unique way to automatically manage how we charge and deploy stored energy. These batteries are not only utilized to store energy but also provide critical contingency reserves that save United Power approximately $300,000 per month. 

Recently, United Power joined forces with three other public power utilities — CORE Electric Cooperative, Platte River Power Authority, and Colorado Springs Utilities — to explore creating a regional transmission project, nicknamed Lariat Loop, that will better serve their member-customers. This collaboration aims to reduce electric transmission congestion, enhance system reliability, and expand access to renewable energy sources, all while supporting the State of Colorado’s ambitions carbon reduction goals. 

Our members are directly involved in the “all of the above” electricity strategy. There are nearly 13,000 solar rooftops in our service territory. We will have a new distributed energy resource management system available in January that will allow additional interaction with our members’ resources such as thermostats and electric vehicles. We are rapidly moving to expand our distribution system operations plan, allowing resources from our larger members, such as oil and gas, to be bid into the Southwest Power Pool market coming in April 2026. 

The bottom line is quite simple. While we support expanding transmission and investing in future technologies, and applaud efforts to bring a wide range of generation to the West, we must be realistic about what can be done today to support our growing member base. United Power lives the “all of the above” mantra every day. We buy wind. We buy solar. We buy natural gas. We buy hydropower. And yes, at times we even buy coal. Our focus remains on providing the most reliable and responsible resources we can in our commitment to you, our members.

As always, please feel free to reach out with your questions, comments, or concerns. I enjoy hearing from you and appreciate your continued support.
