MOUNTAINEER GAS COMPANY

Infrastructure Replacement and Expansion Program

Filing for 2027

NOTICE OF FILING AND HEARING

On July 31, 2026, Mountaineer Gas Company (Mountaineer) filed its annual Application for approval of an Infrastructure Replacement and Expansion Program for 2027 (2027 IREP) with revised IREP rates for 2027, pursuant to W.Va. Code § 24-2-1k, which authorizes the Public Service Commission of West Virginia (Commission) to approve cost recovery of projects to replace, upgrade and expand natural gas utility infrastructure that are deemed to be just and reasonable and in the public interest.

In its Application, Mountaineer forecasts capital investment for calendar year 2027 of $83,000,000 as part of its multi-year plan. The 2027 IREP covers several categories of plant asset replacements and improvements, including mains, service lines, measurement and regulator stations, and house regulators. These plant investments are proposed to be made in Mountaineer service territories throughout the State. These investments are identified in the Application, which is on file and available for public inspection at the Commission’s offices at 201 Brooks Street, Charleston, West Virginia and which may be viewed on the Commission’s website, www.psc.state.wv.us.

Mountaineer proposes to increase IREP revenues by approximately $8,611,000 for IREP investments made from 2025 to 2027 through an increased IREP rate component to be effective on January 1, 2027, within the fixed or volumetric base rate component of its rates, depending on the applicable rate schedule under which service is rendered. Mountaineer projects that if the program and IREP rate increase are approved as requested, the average monthly bill for its various classes of customers will be changed on January 1, 2027 as shown below:

The increases shown above are compared to the rates currently in place and are based on averages of all customers in the indicated class. Each class may receive an increase greater or less than stated here. Individual customers may receive an increase that is greater or less than average. Furthermore, the requested rates and charges are only a proposal and are subject to change (increase or decrease) by the Commission in its review of the filing. Any change in rates and charges will not become effective until authorized and approved by the Commission.

The Commission set a procedural schedule, including a hearing date on the Application that will begin at 9:30 a.m. on November 6, 2026, in the Howard M. Cunningham Hearing Room at the Commission’s offices at 201 Brooks Street, Charleston, West Virginia. If no opposition to the Application is received by the Commission prior to the hearing date, the hearing may be waived and the Commission may issue a final order within 150 days of the Application filing date.
