The Wabash River Project was selected by the DOE in September 1991 as a CCT Program Round IV demonstration project. Construction was started in July 1993 and commercial operation began in November 1995. The demonstration was completed in January 2000, and continues to run as a base-load unit serving the electrical generation need of Indiana.

The Wabash River Project demonstrated use of the E-GAS coal gasification process to fuel a combustion turbine generator, whose exhaust is integrated with a heat recovery steam generator (HRSG) to drive a steam turbine generator. Sulfur removal exceeds 97%. Elemental sulfur is recovered and sold, as is the slag byproduct of gasification.

The demonstration facility is located at the Wabash River Generating Station
near West Terre Haute, Indiana.

Awards

In its September/October 1996 issue, Power Magazine editors named the Wabash River Project as one of five Powerplant award winners for 1996 - the fourth time since 1991 that a DOE-sponsored CCT project had been cited for this prestigious award. Power described the Wabash Project as demonstrating "a technology to bridge the millennium … being proven under the rigors of commercial service." The Powerplant awards are given annually to recognize the "leadership in the application of fresh ideas and new technology and equipment to minimize environmental impact and maximize efficiency." Power revisited Wabash in March 2000 by naming it to the magazine's "Power Plant Hall of Fame."

The Wabash River plant has also earned the Indiana Governor's Award for Excellence in Recycling.
