Tractebel Begins Construction of the Largest CFB Plant in the United States

Tractebel Power Inc., has started construction of a 440-MW lignite fired power plant located at the Phillips' Coal lignite reserve in Choctaw County, MS. The plant will use circulating fluidized bed (CFB) combustors, which will receive lignite directly by mine truck from the mining operation. The two atmospheric CFBs, which will make this plant the biggest CFB in the U.S., are each rated at 220 MW. The CFBs will generate steam for a single 400 MW steam turbine, exhausting to a surface condenser and rejecting heat to the atmosphere with mechanical draft cooling towers.

The Red Hills Power Station, which is located in Choctaw County, MS, will generate power for the Tennessee Valley Authority's (TVA) 161-kV transmission system.

Tractebel Power, Inc. (TPI) will operate the power plant, while Phillips and its partner, North American Coal, will operate the lignite mine. The project is scheduled to reach commercial operation in fourth quarter of the year 2000. The plant is expected to have an operational life of 30 years.
