The MVP Mainline, a 303-mile interstate natural gas transmission pipeline system that spans from Wetzel County, West Virginia, to Pittsylvania County, Virginia, entered operation in June 2024 and achieved its full operational capacity of 2 billion cubic feet of natural gas per day (Bcf/d) in January 2025. In April 2025, it was recognized in a joint report by the FERC and the North American Electric Reliability Corporation for its critical role in helping to avoid supply curtailments during winter weather events and periods of record demand.
In June and July 2025, Mountain Valley Pipeline, LLC conducted an open season to gauge shipper interest in MVP Boost, which was initially anticipated to increase capacity on the MVP Mainline by 500 thousand dekatherms per day (Mdth/d).
The MVP Boost open season received over 1 Bcf/d of shipper interest from investment grade counterparties, leading Mountain Valley Pipeline, LLC to increase the additional capacity provided through MVP Boost to 600 Mdth/d, as described in the application filing to the FERC.
Upon completion, MVP Boost will leverage the tested and approved capabilities of the MVP Mainline system to safely transport up to 2.6 Bcf/d for domestic use. As a demand-driven project, MVP Boost is fully subscribed by investment-grade utilities in North Carolina and Virginia through binding, long-term contracts that ensure reliable offtake.
