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).
