Integrys Energy Services Closes Sale of Wholesale Electric Marketing Business

CHICAGO, April 1 /PRNewswire-FirstCall/ -- Integrys Energy Group, Inc. (NYSE: TEG) today announced that its nonregulated subsidiary, Integrys Energy Services, Inc., has sold substantially all of its wholesale electric marketing and trading business to Macquarie Cook Power, Inc. as part of Integrys Energy Services' strategy to reduce the size and scope of its operations.  Macquarie Cook Power, which was rebranded Macquarie Energy LLC in February 2010, is a subsidiary of Macquarie Group Limited (ASX: MQG).  

The transaction included various power transactions, products and trading positions, including physical forwards, financial transmission rights and derivatives. This portfolio of transactions had an annual average total gross volume in excess of 125 million megawatt-hours over the past three years. The transactions did not directly affect the retail electric or natural gas marketing business operated by Integrys Energy Services.

This transaction will ultimately result in reduced collateral support requirements for Integrys Energy Group of approximately $400 million and completes the divestiture of Integrys Energy Service's wholesale businesses.

J.P. Morgan Securities acted as exclusive financial advisor to Integrys Energy Group and Thorndike Landing acted as lead advisor to Integrys Energy Services for this transaction.
