In 2016, DTE Energy, a BIG utility and midstream company based in Detroit, MI, purchased 100% of M3 Midstream’s Appalachia Gathering System (AGS), located in Pennsylvania and West Virginia, and 40% of M3’s Stonewall Gas Gathering (SGG), located in West Virginia (see DTE Energy Buys Marcellus/Utica Pipelines for $1.3B). The reason? To feed natgas-fired electric plants the utility wants to build (see DTE’s Reason for Buying M-U Pipes: NatGas-Fired Electric Plants). DTE has just cut a deal to buy another 30% of the Stonewall system in WV.
