TVA brings in John Sevier gas plant under budget

The Tennessee Valley Authority (TVA) has increased its natural gas footprint with the addition of the 880-MW John Sevier combined-cycle plant near Rogersville, Tenn., which entered commercial operation April 30.

TVA said April 30 that the project was completed a month ahead of schedule and about $30m under budget. The cost was estimated to be $820m by a TVA spokesperson.

The plant will be managed by a TVA staff of about 30 employees. It is located next to the John Sevier coal-fired plant, where two of the four units will be retired and two units idled at the end of this year.

Another TVA spokesperson said the new combined-cycle plant is not technically “replacing” the coal units. The plant is the second combined cycle facility to operate within the state of Tennessee, and the second new generation site constructed by TVA since 2002. It is the fifth combined cycle site for TVA. TVA’s other combined cycle plants are Caledonia, Magnolia and Southaven, all located in Mississippi; and Lagoon Creek near Brownsville, Tenn. During the recent TVA board of directors meeting, it was also noted that the new combined-cycle plants have been running at a relatively high capacity factor in recent months.
