Our Business


Midstream EQT is seizing opportunities created by the Appalachian Basin’s burgeoning production of natural gas and other energy products. In 2012, EQT Midstream Partners, LP was formed by EQT to own, operate, acquire, and develop midstream assets across 21 counties in Pennsylvania and West Virginia. 

This growth-oriented limited partnership provides midstream services to EQT and multiple third parties through two primary assets: the EQM Transmission and Storage System, which serves as a header system transmission pipeline; and the EQM Gathering System, which delivers natural gas from wells and other receipt points to transmission pipelines.
