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.

NOTICE OF MEETING OF THE BOARD OF DIRECTORS TO AMEND THE BYLAWS OF UNITED POWER, INC.

NOTICE OF PROPOSED AMENDMENTS TO THE BYLAWS OF UNITED POWER, INC. 
500 COOPERATIVE WAY, BRIGHTON, COLORADO 80603.

The Board of Directors proposes to amend the Bylaws of United Power, Inc. (United Power) as follows:

• Replace the word “nonprofit” with “not-for-profit” because there is a legal and operational distinction between the two types of organizations and United Power is a not-for-profit. This correction will align the cooperative’s governing documents with its IRS filing status, note purchase agreements, and related indenture agreements.
• Include language that provides a deadline for a challenge to any election of directors. Notice of the deadline will provide guidance to members and staff on how to handle any challenges to an election. Clarity in the rules will improve the cooperative’s operational efficiency. 

A complete redline of the proposed changes is available on the cooperative’s website at www.unitedpower.com, or members may obtain a hardcopy at any United Power office or via mail by calling 303-637-1300 and requesting that a copy be made available to them at the address on file with the cooperative.

Pursuant to Article 11, Section 8 of the Bylaws of United Power Inc., you are hereby notified that the Board of Directors of United Power proposes to adopt the amendment(s) to United Power’s bylaws at a meeting of the Board to be held on August 27, 2025, unless a written petition is filed at United Power’s headquarters before close of business on August 25, 2025, signed by 100 or more members, protesting the proposed amendments.
