Mr Sheppard will serve as a class A independent director on the audit and compliance, performance review and corporate governance and nominating committees.

Mr Sheppard is currently an assistant treasurer of Chevron. He previously served on the board from March 2004 to April 2007 as a director designated by Chevron. With the April 2, 2007 closing of the transaction between Dynegy and LS Power, Chevron, which was then a Dynegy stockholder, no longer designated any of Dynegy’s directors as their shares converted to class A shares. Chevron has since sold all of those shares and holds no economic interest in Dynegy.

Dynegy’s board of directors will now include eight class A directors and three class B directors who represent the company’s 40% equity owner, LS Power.

Bruce Williamson, chairman, president and CEO of Dynegy, said: One of Dynegy’s strengths is the leadership, energy experience and diversity of skills of our board of directors. We welcome Howard back to our board in his individual capacity and look forward to benefiting from his years of experience in finance and the energy markets.
