TXU Corporation proposes to build Oak Grove, its largest lignite-burning power plant, in northern Robertson County, a predominantly rural area midway between Houston and Dallas.

Robertson County already has one medium sized coal plant (TNP 1) a few miles north of Calvert; a pollution permit application has been submitted to triple the size of this plant. If the pollution permit for TNP 1 and the Oak Grove permit are approved, our county will increase its coal-burning power plant capacity by more than 8 times (305 Mw to 2,600 Mw), becoming home to two immense coal-burning utilities.

While some pollution controls are planned, TXU's permit application does not include analysis of the best technologies available:

  • They did not consider IGCC - gasification - which would be much cleaner. A plant using IGCC coal gasification technology has emissions almost as low as a natural-gas-fired plant

  • They are not willing to blend fuels, which would be cleaner, and easily accomplished

  • They won't consider fluidized bed technology, which is cleaner.

Dr. Neil Carman, chemist and Clean Air Program Director for the Lone Star (Texas) Sierra Club says that
"In TXU’s initial permit application for the Oak Grove plant, the company seeks to emit nearly 2,200 pounds of mercury per year which is the largest amount of mercury emissions for any power plant in the United States."
