* TXU to Select Mitsubishi US-APWR for New Nuclear Power Generation
Mitsubishi Heavy Industries press release

US-APWR reactor technology developed by Mitsubishi Heavy Industries, Ltd. (MHI) is selected by TXU for its new nuclear-fueled power generation capacity.

TXU plans to file applications for combined construction and operating licenses using US-APWR technology for 2-6 gigawatts at multiple sites including Comanche Peak site which has two units in operation. The filings would facilitate commercial operation of the units starting from 2015 to 2020. Friday, March 9, 2007, TXU formally notified its reactor selection to the US Nuclear Regulatory Commission (NRC) and launched the preparation of Combined License (COL) application per 10 CFR Part 52.

MHI has developed the US-APWR based on technologies for a 1,538 MW APWR planned for use at the Tsuruga Power Station Units 3 and 4 of the Japan Atomic Power Company. A variety of modifications are added in reflection of the demands of U.S. customers for enhanced performance; improvements include the world's highest level of thermal efficiency (39%), a 20% reduction in plant building volume, 24 months fuel cycle length, and greater economy by increasing the power generation capacity to 1,700 MW class which is the world largest class. MHI is planning to construct the US-APWR in cooperation with a major engineering and construction company, Washington Group International Inc. in U.S. MHI is jointly promoting this US-APWR with Mitsubishi Corporation in U.S. market.

MHI has established MHI Nuclear Energy Systems Inc. (MNES), a wholly owned subsidiary, in Washington, D.C., and has started procedures to submit an application to NRC for Design Certification of the US-APWR. MHI makes good progress on formal application for Design Certification that will be conducted through the end of 2007.

TXU's selection is believed to be based on the US-APWR's excellent economy, proven safety and reliability, and MHI's comprehensive capability to undertake engineering, fabrication, construction, detailed maintenance and supply of high reliability fuel. In Japan, MHI has engaged in the construction of 23 Pressurized Water Reactors and is constructing one nuclear power plant. MHI will pursue further deployment of the US-APWR technology and promote US-APWR to the utilities who are under consideration of their new reactor type.

Summary of Plant Status - March 25 through June 23, 2005

Unit 1 operated at essentially 100 percent power for the entire period.

Unit 2 began the period at 95 percent power in a coastdown to Refueling Outage 2RF08. On March 26, Refueling Outage 2FR08 began at 11:46 a.m. when the reactor was manually tripped and the main generator output breakers were opened. The refueling outage ended on April 28, 2005, at 12:59 a.m. when the output breakers were closed. The unit achieved approximately 100 percent power on May 4, 2005, and operated at essentially full power for the remainder of the period.

TXU chief earned $55-million in 2004

John Wilder became President and Chief Executive of TXU Corp. in February 2004. In addition to the $1.1 million salary, he received a signing bonus of $1 million. he also earned a $2.5 million bonus under TXU's annual incentive plan and the market value at grant of 500,000 shares of TXU stock to a so-called rabbi trust, which he can draw after leaving company. Altogether, his bonuses totaled about $16 million. Mr. Wilder also received long-term incentive payouts totaling almost $37 million in 2004, reflecting the vesting of one million performance units.

TXU taps Entergy CFO as new CEO; stock surges

TXU Corp. Chief Executive Erle Nye stepped down and was replaced by C. John Wilder. The appointment is effective immediately. Nye will stay on as chairman through May 2005. Wilder, 45, joined New Orleans-based Entergy in 1998 after 20 years with the Royal Dutch/Shell Group. As executive vice president and chief financial officer at Entergy, Wilder was involved in developing strategies for growth, risk management, and financial disclosure. TXU shares jumped to a 52-week high in early trading, rising as much as $1.87, or 7.5 percent, to $26.70 apiece. TXU shares have yet to fully recover from a slump in late 2002, when the collapse of the company's business in the United Kingdom led to job cuts and a slash in the stock dividend. Leo Denault, who joined Entergy in 1999 as vice president of corporate development, will replace Wilder there as CFO.
