The Wabash IGCC plant was originally built by the Wabash River Coal Gasification Project Join Venture, formed in 1990 by Destec Energy and PSI Energy. The project was selected by the Department of Energy in September 1991 as a Clean Coal Technology (CCT) Program Round IV demonstration project. The goal of the CCT Program, which was co-funded by industry and the Federal Government, was to enhance the utilization of coal as a major energy source.
Construction of the Integrated Gasification Combined Cycle (IGCC) plant was started in July 1993 and commercial operation began in November 1995. In 1996, the Wabash IGCC plant was the winner of Power magazine's Powerplant Award. The final report for the project was submitted in 1999, showing that the demonstration project had achieved all its objectives.
After completion of the demonstration period, the Wabash IGCC plant operated commercially until 2016 on baseload dispatch to the power grid for several owners.
1995-1997: Destec Energy
1997-1999: NGC Corporation (renamed to Dynegy Inc.)
1999-2005: Global Energy Inc.
2005-2016: SG Solutions
From 2000-2016 significant optimization was done on the gasification process to reduce syngas generating costs and increase Gasifier uptime. In addition, the Wabash IGCC site continued to support many R&D initiatives for the next generation clean fuel technologies.
The Wabash team has always been a major contributor to the community. It has been a source of pride to have world renowned state-of-the-art industrial technology implemented in Terre Haute, Indiana. It was not uncommon to have visitors from around the world come to the site to see the demonstration of gasification technology. Many of these visitors also included students and professors from our local institutions.
In addition, the plant historically provided some of the highest paying jobs in the area, regularly employing 70 direct and 30 routine contract employees since 1995. Locally, the plant supported the community with over $10 million annually spent with over 100 separate vendors in the Wabash Valley.
