Clean Coal Technology Options for Upgrading Existing Power Plants, The Wabash Experience. Phil Amick, Vice President, Commercial Development Global Energy, Inc.,

Houston, Texas 77002

Several years ago, a previous Secretary of Energy called the Wabash River Coal Gasification Repowering Project in Terre Haute, Indiana the "power plant of the next millennium". The 262 MWe project is a joint venture of Global Energy Inc. and PSI Energy, a part of Cinergy Corp. The facility is a gasification combined cycle repowering of a 1950's vintage unit at a pulverized coal power plant.

The gasification facility utilizes local high sulfur coals (up to 5.9% sulfur ) or petroleum coke and produces syngas for an advanced combustion turbine based combined cycle plant. Wabash River is the cleanest coal fired power plant in the world, of any technology, with SOx emissions less than one tenth of Clean Air Act standards, near zero detectable particulate emissions and no solid wastes. While generating nearly six times the annual power output of the previous unit, thousands of tons per year of SO x, NO x and particulates are being achieved annually.

The Wabash River plant has been operational for nearly six years now, and has gasified over two million tons of coal and petroleum coke. The presentation will discuss current operations and operational challenges as well as briefly recapping the successes in resolving some of the problematic areas from new technology applications.

Advantages of implementing gasification technologies as a strategy for additional capacity while attaining emissions reductions at other existing coal fired power plants will be discussed.

Phil Amick is the Director of Gasification Development for Dynegy's Gasification Business Unit. Dynegy, formerly named NGC Corporation, acquired Destec Energy in 1997 and is now the owner of the Destec Gasification Process Technology. Phil has the responsibility of promoting the gasification process and developing new gasification based projects for Dynegy. He has previously had business management and engineering responsibilities for the Wabash River plant, and was project manager for the syngas facility during its design, construction and start-up.
