Performance and reliability
Ty: How has the Mountain Peak facility performed since coming online?
Mark A. Gabriel: It has been a game changer. United Power has been growing an average of 22 MW a year since 2005. In July 2025, we hit our system peak of 680 MW, and the plant had just come online weeks earlier. Without it, we would have had to buy very expensive power, at times over $220 per megawatt-hour. Instead, the six LM2500XPRESS units delivered local, reliable power and saved us millions in just the first weeks of operation.
Beyond dollars and cents, it is about resilience. We are working to hyper-localize all our resources. These six units dispatch to two substations at the distribution level, which means we can control and manage power directly for our members rather than depending only on distant sources. This site at our Tesla substation also happens to sit right next to a Colorado Interstate Gas pipeline, so we did not need big investments in gas infrastructure. Combine that with our 69kV transmission line, batteries, and the LM2500XPRESS fleet, and you have a complete energy center. It really is a model for the future across the country.
Paired with 11 MW of batteries on-site, they give us a flexible portfolio to balance solar, wind, hydro, and marketplace purchases.
