TXU's Plans to Construct 11 Coal-Fired Plants in Texas
In April 2006, TXU announced plans to build 11 new coal-fired plants. (The press release describing the proposal is here.) An 18-page update in June (here) describes TXU's progress on the plants and gives more detail on the plant costs, risks and return, environmental issues, plant pro formas, and TXU's national strategy.
A list of all coal-fired plants in the U.S., including but not limited to the TXU proposals, is here. The site includes a link to a Google map showing locations.

TXU Generation
TXU's table of generation by fuel source and costs of fuel and purchased power, from the 2006 Annual Report, is here.
TXU's total installed generation capacity before the expansion is shown in the table below. Nuclear and coal-fired plants are defined as baseload units, designed to run almost all the time, shutting down only for maintenance and repair. Natural gas units are primarily peaking units, which come on line as demand rises. A baseload plant might produce electricity, measured in megawatt hours, for 90 percent of the hours in the year. In contrast, a peaking unit might be online and generating electricity for only a few hours a day in the hottest months.
