Over 5,600 MW of IGCC Power Generation Being Pursued in Texas

---

Researched by Industrial Info Resources (Sugar Land, Texas). Texas utilities, private energy producers (PEP) and industrial power producers (IPP) are looking at the development of eight coal and/or petroleum coke integrated gasified combined-cycle (IGCC) power plants equaling almost 4,600-megawatts (MW) of generation. In addition, one developer is also planning to convert two 550 MW natural gas combined-cycle power plants to burn gasified coal or petroleum coke to become IGCC plants. A combined-cycle plant consists of one or more combustion turbine/generators that supply heat to one or more heat recovery steam generators plus a steam turbine/generator.

Texas utilities, TXU (NYSE:TXU) (Dallas, Texas) and Austin Energy (Austin, Texas) are both looking at building IGCC plants in Texas. The city of Austin is looking at a 500 MW IGCC plant in Matagorda County. TXU is looking at developing two 600 MW IGCC units, one utilizing Powder River Basin (PRB) coal and the other utilizing lignite coal as feedstock. TXU is considering their recently cancelled ultra supercritical sites in addition to greenfield sites as future locations for IGCC generators.

Texas is proposing two sites for the Department of Energy’s (D.O.E.) 275 MW FutureGen demonstration project. FutureGen is a $1 billion initiative to build the world's first integrated sequestration and hydrogen production research power plant. The demonstration project will utilize gasified solids for IGCC unit that is intended to create the world's first zero-emissions fossil fuel plant. When operational, the prototype will be the cleanest fossil fuel fired power plant in the world. The two sites are near Odessa and Jewett. Site selection is to be announced in October.

IPP’s that have indicated interest in IGCC development are CITGO Petroleum Corporation and Motiva Enterprises. These petroleum refiners are looking at adding IGCC units at two of their Texas refineries. CITGO is proposing a 600 MW project at its Corpus Christi refinery and Motiva is proposing a 200 MW IGCC unit at its Port Arthur refinery.

There are three PEP’s that are proposing four IGCC generation projects in Texas. Two are grassroot plants and the other two are converting combined-cycle units to IGCC projects. The conversion projects are being proposed by Navasota Energy Partners LLC (Houston, Texas) on its 1,100 MW Wharton and Odessa Projects. The largest project is the 1,220 MW petroleum coke Lockwood IGCC project in Fort Bend County. This project is a joint venture between Cogentrix (Charlotte, North Carolina) and Hunton Energy (Houston, Texas). Lastly, there is the 600 MW petroleum coke/coal Nueces IGCC Energy Center being proposed by the Tondu Corporation (Houston, Texas).
