Filing for 2026
NOTICE OF FILING AND HEARING
On July 31, 2025, Mountaineer Gas Company (Mountaineer) filed its annual
Application for approval of an Infrastructure Replacement and Expansion Program for
2026 (2026 IREP) with revised IREP rates for 2026, pursuant to W.Va. Code
§24-2-1k, which authorizes the Public Service Commission of West Virginia 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 2026 of
$77,000,000 as part of its multi-year plan. The 2026 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 $5,239,000 for
IREP investments made from 2023 to 2026 through an increased IREP rate
component to be effective on January 1, 2026, 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, 2026 as shown below:
Mountaineer Gas Company – Proposed
Type of Customer $ % Increase Increase
Residential $ 1.55 1.93%
Commrcial $ 4.12 1.39%
Large Commercial (*) $218.55 0.43%
Large Commercial (*) $276.83 0.17%
Industrial (*) $297.22 0.26%
Wholesale $44.28 0.64%
(*) Percentage increases for Large Commercial and Industrial customers assume
transport customers purchase their natural gas at the same price as the Company’s
Purchased Gas Adjustment rate.
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 14, 2025, in the Howard M.
Cunningham Hearing Room at the Commission’s offices at 201 Brooks Street,
