Set for completion in 2012, the facility is expected to be the largest, most advanced commercial IGCC plant in the world. It's expected to generate up to 618 megawatts of electricity, or enough power to 500,000 homes.
IGCC technology converts coal to gas, where pollutants such as mono-nitrogen oxides, sulfur oxides, mercury and particulate are removed.
The tech allows the plant to capture carbon dioxide prior to combustion, cutting down on greenhouse gas emissions compared to a traditional coal plant.
In a statement, GE Power & water gasification general manager Monte Atwell said the technology needs federal support and incentives to compete on the world stage.
"Already, China is emerging as a world leader in the construction of more efficient, less polluting coal plants," Atwell said. "If America doesn't act swiftly, the opportunity to export U.S. IGCC technology to coal-rich nations like China and India may be lost."
IGCC technology is also used in plants in Barstow, Calif. and Polk County, Fla.
