INTERNATIONAL BROTHERHOOD OF ELECTRICAL WORKERS LOCAL 51

SUPPORTS THE DYNEGY AND LS POWER MERGER

SPRINGFIELD, ILLINOIS (March 07, 2007) – International Brotherhood of Electrical Workers (“IBEW”) Local 51 today issued a statement in response to questions received regarding the union’s position on the proposed merger between Dynegy Inc. (NYSE: DYN) and LS Power and the associated shareholder vote.

“IBEW Local 51 strongly supports the merger between Dynegy and LS Power and recommends a vote “FOR” the adoption of the Merger Agreement and approval of the merger,” said Dominic Rivara, Business Manager of IBEW Local 51. “This announcement alone has financially strengthened the company, as evidenced by Dynegy’s stock performance since the date of the announced transaction on September 15, 2006. We expect to benefit from continued improvement upon the approved merger, along with future growth and consolidation opportunities that Dynegy may explore,” Rivara added.

For the merger to be approved, Dynegy requires the favorable vote of at least two-thirds of all outstanding shares of Dynegy’s Class A common stock.
