INFRASTRUCTURE REPLACEMENT AND EXPANSION
PROGRAM (IREP)
On July 31, 2026, Mountaineer Gas Company filed its annual Infrastructure Replacement and Expansion Program (IREP) application for 2027 (Case No. 26-0704-G-390P). Mountaineer requested Commission approval to increase IREP revenues by approximately $8.6 million effective January 1, 2027. As part of its multi-year plan, the Company forecasts $83 million in capital investment for 2027 alone — out of a broader $475 million planned over the 2027–2031 five-year period — directed primarily toward the replacement of aging baresteel mains. Mountaineer also plans to replace some older service lines, measurement and regulator stations, and house regulators.
The IREP rate would increase by $0.423 and $0.243 per Mcf for residential and general service customers, respectively. The average monthly bill for a residential customer would increase $2.40 or 2.79%, and the average monthly bill for a general service customer would increase about $6.56 or 1.96%. IREP rates for wholesale, large general service, and industrial customers will also see increases.
The Public Service Commission of West Virginia (PSC) will review the Company’s request and may adjust the rates. As with all filings, the proposed rates will not become effective until authorized and approved by the PSC.
