Midwestern Gas to serve new gas-fired plant at TVA’s Paradise site

Midwestern Gas Transmission (MGT) filed an April 7 notice with the Federal Energy Regulatory Commission that it intends to apply for approval of a gas pipeline to serve a planned new gas-fired power plant at the Tennessee Valley Authority’s Paradise coal plant in western Kentucky.

TVA late last year said it planned to shut part (Units 1 and 2) of the Paradise coal plant and build gas-fired capacity in its place. MGT said it has gotten a request from TVA to construct a pipeline lateral from its mainline in Ohio County, Ky., to the Paradise site in Muhlenberg County, Ky.

TVA told the company it plans to replace two coal units at the site with a new combined cycle plant in order to meet federal Mercury and Air Toxics Standards compliance needs. The new combined-cycle plant would be in-service by September 2017.

MGT proposes to meet TVA’s request by constructing and operating an approximate 15-mile, 24-inch-diameter natural gas pipeline lateral system. The pipeline lateral system will be fully automated with measurement facilities to continuously monitor natural gas flow between the pipeline and the TVA Fossil Plant. At this time, TVA also is considering opportunities available for securing mainline capacity on MGT’s pipeline system, MGT noted.

The April 7 filing at FERC is officially a request to initiate a National Environmental Policy Act pre-filing process, with plans to file a formal certificate application with the commission in October of this year, with a pipeline lateral construction start in September 2015.

The pipeline project contact is: Matthew Gillett, Project Manager, ONEOK Partners GP LLC (MGT’s Operator), 100 W. 5th Street Tulsa, OK 74103; (918) 588-7382, matthew.gillett@oneok.com.

TVA in November 2013 released a final environmental assessment on the Paradise options that contains Alternative C, the gas-fired option. Rejected was the alternative that would have seen the installation of pulse jet fabric filters for particulate control on Units 1 and 2, which have a total of 1,408 MW of capacity. The newer, 1,150-MW Paradise 3 coal unit would not be retired. The TVA Board of Directors gave President and CEO Bill Johnson the power to decide exactly when to shut the two coal units.

Alternative C includes construction and operation of a new combustion turbine/combined cycle (CT/CC) plant with a summer capacity of up to about 1,025 MW when operated in combined cycle mode. This alternative also includes associated gas pipeline(s). The CT/CC plant would be located just north of the existing coal pile and to the west of the Green River on an approximately 50-acre site.
