The Mountain Valley Pipeline (MVP) is an under-construction natural gas pipeline in the United States from northwestern West Virginia to southern Virginia. The MVP is 304 miles (489 km), and there is also a proposed Southgate Extension to the pipeline which runs 75 miles from Virginia into North Carolina. The completed pipeline would have a capacity of 2 million dekatherms (Dts) of natural gas per day, with a large quantity of that gas being produced from the Marcellus and Utica shale formations.
