PRINCETON, N.J.--(BUSINESS WIRE)--Sept. 5, 2007--NRG Energy, Inc. (NYSE:NRG) has announced that David Crane, President and Chief Executive Officer and Robert Flexon, Executive Vice President and Chief Financial Officer, and other senior NRG executives, have established trading plans in accordance with Rule 10b5-1 of the Securities Exchange Act. Rule 10b5-1 permits individuals who are not then in possession of material nonpublic information to establish prearranged plans to buy or sell stock. The rule allows individuals to buy or sell shares of stock at a specific price in the future, regardless of any subsequent material nonpublic information.

It is the viewpoint of the Company that enabling prudent financial planning is an essential component of management retention. In order to mitigate potential market concerns about the timing of share transactions, the Company has requested that all of its Section 16 officers, including its CEO and CFO, who elect to buy or sell NRG shares, do so pursuant to Rule 10b5-1 plans. Under their individual plans, Crane and Flexon intend to exercise a portion of their original grants, including vested stock options, and sell the underlying net shares of NRG common stock. After completion of all of the sales contemplated by today's trading plans, both Crane and Flexon will continue to hold ownership interests in NRG well in excess of the Company's current stock ownership guidelines. (Six times and three times base salary in the case of Crane and Flexon, respectively.)
