INFRASTRUCTURE REPLACEMENT AND EXPANSION PROGRAM (IREP)

Mountaineer filed with the PSC on July 31, 2025, to increase the IREP rates for all customer classes. The company plans to spend $77 million in 2026 on infrastructure improvements, with most of the investment going toward replacing aging bare-steel distribution mains.

This investment ensures Mountaineer continues to provide safe, reliable service to its customers. The proposed increase was $0.258 per Mcf for residential customers and $0.147 per Mcf for general service customers.

Based on average annual usage of 72 Mcf for a residential customer, the annual increase is approximately $18.60, or about $1.55 per month. On December 17, 2025, the PSC issued an order approving the rates effective January 1, 2026.
