Mainline/Sunrise/Ohio Valley Connector Transmission System
The Equitrans Mainline/Sunrise/OVC transmission system makes up the majority of its FERC-regulated storage and transmission assets with approximately 750 miles of interstate pipelines and pipeline interconnects with National Fuel, Columbia Transmission, Dominion Transmission, Tennessee Gas Pipeline, Texas Eastern, Rockies Express Pipeline, Peoples Natural Gas Company, and Columbia Gas of PA. The Mainline transmission system has had two major pipeline expansions over the past several years, the Sunrise Pipeline and the Ohio Valley Connector. The Sunrise Pipeline was commissioned in July of 2012 and added 400 MMcf per day of capacity with access to Texas Eastern via the Jefferson Compressor Station. The Sunrise system was further expanded in September of 2014 by 550 MMcf per day through the addition of compression at the Jefferson Compressor Station. The Ohio Valley Connector was placed into service in October of 2016 and added 850 MMcf per day of certificated capacity with access to Rockies Express Pipeline via the Plasma Compressor Station.
Ohio Valley Connector
The Ohio Valley Connector began natural gas transportation service from northern West Virginia to Clarington, Ohio on October 1, 2016. The 37-mile pipeline, an extension of the existing Equitrans system, was certified by the FERC at approximately 850 MMcf per day total capacity and is backed by a 20-year transportation service agreement with EQT Energy, LLC, an affiliate of EQT Corporation, for 650 MMcf per day of firm transmission capacity. The Ohio Valley Connector utilizes two new compressor stations with approximately 38,000 horsepower combined – the Corona Station in Wetzel County, West Virginia and the Plasma Station in Monroe County, Ohio – and connects with the existing Equitrans Mainline and Sunrise Transmission System and the Rockies Express pipeline.
