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.
