W.S. Lee combined cycle gas-fired plant - click for larger version
We spotted news from Duke Energy that the company has begun operations at a brand new natural gas-fired electric generating plant in Anderson County, South Carolina. The W.S. Lee Station is a 750-megawatt combined-cycle natural gas plant that began serving customers on April 5. Duke began construction of the $700 million plant in 2015. It sits on the same site as two former coal plants that were shuttered in 2014. A third coal plant at the site was previously converted to burn natgas. Why do we care about a new electric plant launching in SC? Because it's fed by natural gas, and we believe at least some of (perhaps most of) the gas feeding it comes from the Marcellus/Utica region. According to Duke's press release, "The unit receives natural gas through a new dedicated pipeline that branches off the transcontinental mainline." We're pretty sure they're referring to the Williams-owned Tranco (Transcontinental) Pipeline that crosses through Anderson County. Transco is the pipeline feeding the new power plant. Transco is bidirectional and increasingly carries Marcellus molecules south--some molecules all the way to the Gulf Coast (see Is Marcellus/Utica Gas Getting Exported from Cheniere’s Sabine Pass?). It stands to reason that it is Marcellus gas feeding, at least in part, this new plant located in Dixie...
