Moundsville Power LLC on July 3 filed with the West Virginia Public Service Commission a siting certificate application on its 549-MW, gas-fired, combined-cyle project in Marshall County in northern West Virginia.
“The plant’s construction will be initiated in late-2015 and when placed in operation in mid-2018 will have a faceplate capacity of 549 megawatts,” said an economic study that was included with the application. “Resulting power will be sold into the PJM regional electric power grid.”
Total project construction costs (including financing charges and fees) over the construction phase are estimated at $615m (2013 dollars) with 45% of construction costs provided by West Virginia workers and firms.
Moundsville Power said it plans to purchase its natural gas fuel supply needs ofapproximately 67,500 MMBtu per day from an interconnection with a Texas Eastern pipeline. The Texas Eastern pipeline transports significant volumes of West Virginia natural gas. By 2018 the Texas Eastern pipeline will have approximately 2,700,000 MMBtu per day of supply interconnection capacity located in West Virginia (current supply interconnect capacity in West Virginia is 1,600,000 MMBtu per day, and there is currently an additional 1,100,000 MMBtu per day of interconnection supply capacity additions planned within the state).
Moundsville Power plans to purchase its ethane fuel supply needs of approximately 22,500 MMBtu per day from a connection with an ethane pipeline that runs along the path of the Texas Eastern pipeline. This ethane will be blended with the natural gas purchased off the Texas Eastern pipeline. When ethane is not available Moundsville Power will increase its purchases of natural gas off the Texas Eastern pipeline and burn all natural gas. The ethane pipeline runs from Blue Racer Midstream‘s Natrium Gas Processing and Fractionation Plant in Marshall County to William‘s Oak Grove Processing Plant in Marshall County.
The plant will use $105m (2013 dollars) annually of natural gas and ethane fuel supplies sourced through long-term fuel agreements. A third party will construct gas interconnections at an additional cost of $15m (2013 dollars).
Land will be acquired from Honeywell International Inc. and construction undertaken through a turnkey construction agreement with General Electric and an engineering, procurement and construction contractor.
Also attached to the July 3 application is a June 2014 system impact study for this project from PJM Interconnection. The point of interconnection requested is a direct connection to the George Washington 138-kV station via two 138-kV breakers.
