Dynegy Announces Dissolution of Development Joint Venture

HOUSTON--(BUSINESS WIRE)--Dynegy Inc. (NYSE:DYN) today announced that it has entered into an agreement with LS Power Associates, L.P. to dissolve the two companies’ development joint venture. Under the terms of the dissolution, Dynegy will acquire exclusive rights, ownership and developmental control of all repowering or expansion opportunities related to its existing portfolio of operating assets. LS Power will acquire full ownership and developmental rights associated with various “greenfield” projects under consideration in Arkansas, Georgia, Iowa, Michigan and Nevada, as well as other power generation and transmission development projects not related to Dynegy’s existing operating portfolio of assets. LS Power will receive approximately $19 million in cash during the first quarter 2009 to reflect the relative value of assets exchanged. Additionally, Dynegy will record a loss in 2009 related to the transaction.

“The development landscape has changed significantly since we agreed to enter into the development joint venture with LS Power in the fall of 2006”

“The development landscape has changed significantly since we agreed to enter into the development joint venture with LS Power in the fall of 2006,” said Bruce A. Williamson, Chairman, President and Chief Executive Officer of Dynegy Inc. “Today, the development of new generation is increasingly marked by barriers to entry including external credit and regulatory factors that make development much more uncertain. In light of these market circumstances, Dynegy has elected to focus development activities and investments around our own portfolio where we control the option to develop and can manage the costs being incurred more closely.”

During an investor conference call on December 10, 2008, Dynegy announced that it was re-evaluating greenfield development options, as well as two projects under construction – Plum Point in Arkansas and Sandy Creek in Texas. Today’s announcement has no impact on the projects under construction. The company is continuing to re-evaluate its future participation in the Plum Point and Sandy Creek projects, which are expected to enter into commercial operation in 2010 and 2012, respectively. The company has previously sold portions of its interests in the two projects. Dynegy currently owns approximately 20 percent of the 665-megawatt Plum Point project and approximately 30 percent of the 900-megawatt Sandy Creek project.

Through its subsidiaries, Dynegy Inc. produces and sells electric energy, capacity and ancillary services in key U.S. markets. The power generation portfolio consists of more than 18,000 megawatts of baseload, intermediate and peaking power plants fueled by a mix of natural gas, coal and fuel oil. DYNC
