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%
Commercial $4.12 1.39%
Large Commercial (*) $218.55 0.43%
Large Commercial — I (*) $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, Charleston, West Virginia. If no opposition to the Application is received by
