AES Announces CEO Transition

ARLINGTON, VA, September 6, 2011 – The AES Corporation (NYSE:AES) today announced that President and Chief Executive Officer Paul Hanrahan intends to leave the company November 30, 2011. He will step down from his position effective September 30, 2011, transitioning his management and board responsibilities to the company’s Chief Operating Officer, Andrés Gluski. Mr. Hanrahan, who led AES through a period of extraordinary growth during his nine year tenure as CEO, was the chief architect of AES’ capital structure re-alignment over that same period as well. Over the next 90 days, he will be assisting the company in carrying out an orderly transition.

Mr. Hanrahan, who has been with AES for 24 years said, “I identified Andrés as my successor over three years ago and he has gained valuable experience during that time in his role as AES’ Chief Operating Officer. I am confident that he will be successful in his new role as well; as a long time AES shareholder, I look forward to seeing the company continue to flourish under his guidance.”

Andrés Gluski, 53, has been Executive Vice President and Chief Operating Officer of the Company since 2007 and has spearheaded the turnaround of some of AES’ most significant businesses, as well as its major expansion program in Chile. Andrés is currently Chairman of AES Gener in Chile and Brasiliana in Brazil, is a member of the Board of the Edison Electric Institute and has also held the position of CEO and CFO of some of AES’ largest affiliates since joining the company in the year 2000. Prior to joining AES, Andrés held a number of senior level positions in telecommunications, energy, government and financial services institutions such as Grupo Santander and the International Monetary Fund.

As a longtime member of the AES management team, Mr. Gluski said, “We will fully implement the new strategy of focusing on our core markets and continue to enhance the competitiveness and efficiency of our businesses. I look forward to working with our strong, experienced executive team and building on AES’ unsurpassed strategic footprint in the global power market to help take the company to the next level.”
